But what do you think? Should we be trying to use agrivoltaics everywhere? Are there any other dual use renewable energy examples that you know about? If you liked this video, be sure to check out 28,000 Year Nuclear Waste Battery? Diamond Batteries Explained ua-cam.com/video/VWwKqSzakYU/v-deo.html
These communities that are pushing not-in-my-backyard issue are lucky they have word in edgewise because in Native communities and in minority communities when they put chemical plants in those communities they do not have the ability to say no.
To Rob the writer, The water use statistic 0:13 for the livestock is a bit disingenuous, for example most of the water that the livestock drink does double duty since it also irrigates the grass grazing land (which IMPORTANTLY is usually low quality land Not suitable for crop production in the first place)
I'm wondering if it would be more cost effective to have a solar-powered-multi-level-vertical-hydroponic-farm-warehouse built on the same land rather than an agrovoltaic? What's the most amount of food that can be grown, harvested, and shipped for the least/most efficient amount of energy in 1 square meter? (Big brain time. Lol.) Cheers!
In India, we do something like this by placing solar panels at the top of canals. Because there are lots of canals in India. The extra benefit is solar panels reduce the loss of water due to evaporation providing extra for agriculture. The shade also prevents the growth of algae in the water. And the presence of water underneath keeps the panels cool.
As a Dutch Greenhouse Manufacturing Engineer I can already tell you that we calculate the steel constructions with the posibility to directly or later install solar panels. This means that when the end customer wants to place solar panels he can do so without any repurcussions from the local governments as the building permit and the construction calculations are already in place for any eventual agrivoltaic farming. But your story has enlightened me in a few more ways so thank you for that!
Thanks for the good news (news for me, not news for the Dutch). Big players on the food market will drive this development. Here in Germany the NIMBY mentality is a big problem and I doubt that forward-looking engineering like this would have any chance for approval by decision makers. The video is incredibly well done. Channel subscribed.
Sunny California with it's water shortages comes to mind for this. Saving 50% water costs, adding income from power generation and maintaining same yield - a win-win.
I’ve seen California crops under plastic tents. We should try replacing some of this with solar panels. California’s desire to promote solar power should be compatible with this.
yes, and there's also the opportunity to tailor the solar panels to light frequencies that plants don't prefer. With semi-transparent panels allowing the light through that plants like the most, we can make up the energy production shortfall caused by currently being forced to space the panels out (like on the raspberry farm).
@@pradeepkharta5953 That, sir, is an important question that the psychopathic corporations, who make trillions from wars, would prefer people to ignore.
To me agrivoltaics seems to be most effective in smaller operations where heavy machinery isn't used. The raspberry farm was a perfect example of that. Basically if it grows in a plastic tunnel and it's harvested by hand, agrivoltaics will probably be perfect.
@@mcsanad That depends on who owns the solar panels. If they are owned externally then it probably wont affect it at all. If the farmer owns them, it possibly could, but then the higher guarantee on yield means less waste, the shade means less water usage and the electricity needed by the farmer would come from the panels and not the inflated grid prices. So it could offset the installation costs.
@@Ben.Royals well from my point of view planting strawberries on fertile land under solar panels might be a great source of power but the money you lose out on by not planting crops is really unequal. If, the panels are owned by the same person that manages and sells the strawberries and they'd like to cover the cost of the panel, it'd either take them multiple lifetimes to get the price back or to sell the strawberries at a super high price. This idea was obviously made by someone who has never done agricultural planning or work. Instead, putting solar panels on your rooftop, perhaps vehicle hangar or even a barn covers around the same area if not more. This way the farmer is independent from the grid and had more land to cultivate with and make bigger profits than he ever could with measly strawberries. Oh and I forgot to mention, this way the price of bread and other products that come from agriculture won't rise so you get to buy your daily bread for an alright price instead of buying strawberries with sky high prices. I say this is the best possible use, not wasting any fertile land and still getting their own power :)
Best of luck... remember you have to compromise (optimize...???) between food and energy production .. depending upon where/what you farm and Solar Generation...If "up north" maybe a fully enclosed AV System could/would provide 12 month growing season in a Greenhouse like environment... and remember as you "grow solar electricity" too you can provide heating too (use heat pumps that have a COP of 4+ ... COP=HeatOut/Heat In)..
Farmers in Georgia are now growing cash crops that in the past would just burn up, but with the mix of daily sun and shade they are growing crops with a higher cash value than just peanuts and onions.
@Angie Mead King I hope someday, I can visit your farm. Nag-aaral ako dito sa Canada para maging mas efficient at responsible farmer sa atin. I love what you're doing there. Ingat! :)
I have a home garden/homestead in the desert and I'm constantly having to use shade cloth to protect my crops. Even sun loving crops like peppers can get burnt to a crisp if it gets particularly hot and bright. I'm legit considering trying to slap together a home setup like this.
That is SO exciting! You posted this 3 months ago. I hope you'll update us on your progress. I'm about to move f/desert, where we've been getting 11"rain/year, to a one acre, unimproved homestead that gets 56"/year. I hope to slowly put in a no-dig, permaculture garden system. Although water will not be a problem, I think the challenges of excess sun and affordable energy are problematic everywhere.
@@HeloisGevit More than one billion people on Earth live in deserts. In addition, many grasslands and even forests are desertifying due to extreme drought and intensifying heat. There are many food producing plants that are heat and drought tolerant, so we can grow food locally in arid climates but we still need to adapt to environmental factors in the way we grow food. I live in the Sonoran Desert. I have a food forest in my backyard. In addition to improving the soil and cleaning the air, it adds moisture to the air and keeps the temperature lower in summer and higher in winter. With ground-level irrigation I use less water to keep everything going than the neighbors who have no plants at all but wash cars, let the kids play with the hose, or have a pool. My water bill is lower and yet I have groceries growing year round. Growing in the desert improves the local environment, provides nutritious local food, and encourages more rainfall.
I wish that instead of the "car broiler" top deck on parking decks in urban areas, the top deck would be covered with solar panel for shading cars & people, as well as generating electricity. This could be beneficial for powering more charging stations in the deck.
I've been thinking about canopies above parking lots for some time - not just the car broiler either. Think about the acres of parking in front of the grocery store - what if it were covered with solar canopies? Grocery stores use a ton of electricity for the HVAC and refrigeration units, even if they never generated enough to sell to the grid, they could radically offset their own load.
@@leifhietala8074 The issue is the support pylons. If the structure isn't self supporting then the poles discourage people (especially with trucks) from shopping there. Those panels and mounting are HEAVY. Notice in this video they optimized for tractors in one direction only. One local grocery with underground parking has a LOT of spaces with concrete pylons where doors open. I would say about half of the parking spaces are comfortable to use for most drivers. (it is a 12 story apartment building on top of that structure) The apartment parking is in the pedestal so far less "support" needed.
@@leifhietala8074 The parking lot at my local community college has solar canopies. And the elementary school has a tall one which adds shade for the kids to play under.
There are also new solar panels that allow the wave lengths that plants need to go mostly through the panel. This would be ideal for greenhouses as they already have the metal frames.
Glad to see a SMART application of solar on land that does not waste the land underneath. The shade the panels produce should be optimized. Parking lots, the building underneath in hot climates
@@Slebonson Been to Disneyland (Paris) a few weeks ago they where doing the same to their parking lot near the main gate (was still in the early stages of construction tho)
This seems important. For me the measure is the production of two hectares of agrovoltaics, compared with 1ha of traditional agriculture and 1ha of normal photovoltaics. I like the idea that panels can produce electricity and at the same time produce useful shade.
I can imagine Agrivoltaics making big strides in the future. I feel like right now it's just in its starting phases like many other green energy production ideas, but maybe once more research has been done and the benefits of using agrivoltaics is better demonstrated and documented, it can really take off.
Although I did not know the concept existed I imagined it and went searching for just this idea. I searched ‘can you grow under solar panels?’ and was VERY PLEASED to find this video on agrivoltaics!!!! Thank you for this beautifully explained video. We are building a home in Jamaica and I was saddened by the builder’s plan to create a solar park which would use up so much of the precious land space (a slope that has to be terraced) that I had plans to create garden spaces. I wish you were closer to Jamaica so I could actually see the agrivoltaics in person. Thanks again for this video!
Helped conduct research at the University of Arizona on agrovoltaics! All of the crops under solar panels produced significantly more, because of the reduced heat stress. The greatest difference was the tomatoes, as the control group in the sun didn't fruit at all so the percentage increase in yield was a problematic way to summarize the results as we were dividing by 0.
@@Matt-dc8lp solar panels maybe replace shade cloth? and I don't think Matt really provided enough details on the design of the experiment for you to dismiss it without asking for more clarification
Yeah reduced heat stress as in direct sunlight, other wise the covering panels gather and radiate heat into the atmosphere adding to the heat island effect. Less CO2 produced maybe but definitely heating the local atmosphere. Doesn't CO2 do that already?
@@UndecidedMF I'm glad to see you're helping promote the Just have a think guy, the more good quality information that gets out there the better off we're all are.😁

More use cases 1. Solar panel over Parking lots 2. Solar panel over Fish tanks, aquaculture 3. Solar panel over agriculture water canals 4. Solar panels over the hydroponic, aquaponic, or aeroponic farm. Use of grow lights may be needed. 5. Solar panel over cattle shelters 6. Solar panel over building structures
In Pakistan, we have a project underway to put floating solar panels over water dams. Makes the surface area usable, reduces water evaporation and helps keep the panels cool and I don't know the technical details but somehow it also helps improve the efficiency of panels too (in terms of generating energy per unit).
Fish pond covered with a PV installation. PV panels shade the water, reduce evaporation and keep the water cool, while the remaining water evaporation cools the PV panels.
Matt, it seems like, with some research, this could be a win-win for both energy and crop production. I saw somewhere that people were installing solar panels over canals. The panels reduced evaporation of the canal water, and kept the underside of the panels cooler, increasing efficiency.
@@nct948 I suppose sailing boats (with masts) wouldn't use the canals, so the panel are mounted maybe 2-3 meters above the banks, to clear the boats. I guess they figure this out before they build them ! Maybe what I saw was actually irrigation channels (rather than navigable channels).
They should do that here in az over the aquaducts. Would be perfect to minimize evaporation and generate power. No boats of any kind are allowed in the aquaduct anyway. Perfect solution.
Veritasium did a video about a California water supply putting plastic balls into their reservoir, I imagine putting solar panels over it instead could actually do quite a bit of work out there. Providing energy for the area, preventing birds from getting near it (he explains why it's an issue in the video) and reducing evaporation would actually save them loads of money in regards to water. Though, I'm sure the repairs and installation likely wouldn't be as cheap as building this same system over land, since they'd need to put supports in the middle of the water.
Sometimes I wonder what the world would have looked like without innovations like this😊, my advice for everyone, both in the agricultural industry and elsewhere, is to evolve with the world in others so as not to to be left behind
You are absolutely right, the innovation of individuals and industries is gradually making the world a better place and if you are not careful and follow the trend you will be left behind, a perfect example is the introduction of crypto- currencies as a globally acceptable means of payment
Sorry for the inconvenience, I just had to add. Cryptocurrency is the future of money and a very good way to invest and make extra profit, I am grateful to Mr. Larry Kent Nick for introducing me and making me earn so much thanks to this new innovation
I thought I was the only one benefiting from the good works of Larry Kent Nick I made over $45,000 investments with him I bless the day I was introduced to him
the fact that you promoted the other video by "Just have a think", a competitor, shows that you really care about getting the word out! Plus, your whole manner of presentation shows that you really value and enjoy the service you are providing. If only more people could find their calling like you have ! Thanks, you are inspiring.
you could be right or wrong depends on your expertise, I once made such loss when i invested thinking i have gathered enough trading skills from youtube videos but now its a different ball game for me because I was lucky to have met "Tamara Diane Hagan", a financial manager and stock expert, I have made more than $165,000 in 6 weeks under her supervisions.
I have same 2018 Model 3 RWD LR...all the same options including FSD. Similar happiness on my end after 5 years(8.1.18 is 5 years). My range declined a little more than you. 100% now = 278 miles, and seems to have stayed there a long time. I went ahead and wrapped my whole car a few months ago to give it new life. It worked. Glossy Cosmic Blue. Love this car!
This is just the video upload that I needed. I have a roof top garden, and I was looking for space to install a solar plant for my house. Your video has given me a totally new perspective. Now my mind has started working.
Several decades ago some articles were written about the potential benefits of putting farming equipment on rails in order to not compact the earth under the wheels. At the time I recall the major advantage as being reducing the energy consumption of the equipment while working the soil. Guiding the equipment through the rows between the solar arrays effectively achieves this goal. Furthermore, the structures could provide attachments for a hot shoe or catenary power takeoff to power electric equipment without the need for large battery packs. I believe fuel is a significant cost for farmers. Reducing the energy cost to the farmer could be further justification.
Agree. APV gets even more interesting when you further utilize the overhead structure to distribute power allowing the farm implements to be electrified. As we move towards decarbonization, fossil fuel use in industries like agriculture will need these solutions!!
@@daubentons1 I think you are well on to it- the original poster had no budget to pay for the rails, cross ties, maintenance- or the connector rails needed to get from one field to another. Same thoughts occur to me for farm equipment powered by direct take of from the overhead PV grids. But good thoughts to start from! FR
Over the long run it probably is better. But there seems to be significant initial cost that would keep anyone from doing that without federal assistance.
As an employee of a company that operates of some of GroenLeven's solar park portfolio, seeing a pilot project of theirs so close to home featured in this video was a very pleasant surprise! For anyone who wants to know, there are currently more Dutch shade-crop farmers installing solar on top of their greenhouses (not as a pilot, but as actual revenue generating projects). Driving through the vast greenhouse landscape north of Amsterdam and The Hague you can see many of these popping up, great development to see :)
This doesn't surprise me to be honest. With the dutch farmers fighting for their land and Russia cutting off oil, they definitely need a little bit more self-sustainability/cost mitigation.
Bi-facial panels mounted vertically on stilts.. Thank you very much for the idea.. We are embarking on a project integrating solar farm with existing aquaculture. We thought the runaway commodity price has torpedoed our dream.. Once again, thank you very very very very much
I have the hobby to recommend sci-youtuber to science-fans. I'm often called random or even robot for that, but whatever. I keep going for those few that say 'Yes thanks'.
The dual use aspect reminds me of trials with floating solar panels, over water reserves and canals with no transportation, to harvest energy and reduce evaporation in hot climates.
When it comes to future technologies this is without a doubt one of the most interesting and accessible channels on UA-cam. Thanks for all your work and research Matt
Hello Matt, now that I'm retired, my plan is to give hydroponic farming a try. I was concerned about the world getting hotter. In NJ the past summer was unbearable. I love the thought of combining these 2 products. It is a win-win for everyone. Last week, I went to a farm. I saw that they used grape vines over a chicken coup. They said that this was a win-win for the past few years. Why buy chicken waste ! I found this fascinating . Keep up the great work !
This is something I've been thinking a lot about recently. Really love the concept. It turns something which is a liability and turns it into an asset.
I saw this a few years back at the Biodome in Arizona as a study, it help ed keep temperatures way lower for the plants in arizona's aggressive heat, and helped growth all around.
I love how you wrapped up your thoughts on PV Farming at the end. Really well put on all the challenges faced. Also, Just Have A Think is such a good channel for Climate issues. This may be my favorite episode from you yet Matt!
good idea (understandably what's shown here is testing and proof of concept) rather than use traditional mass produced panels that would go on the roof of my house, they should create a bespoke/optimize panel for this use case. 6:40 - like the "strawberry panels" shown with more spacing for light transmission, i suspect somebody somewhere is working on what you propose for a 2nd/3rd phase test. the results so far seem promising and could be even more so with some "tweeks". #POTATOPANELS , #TOMATOPANELS
@@nateman10 I've seen a couple of videos about solar greenhouses. This can address a number of problems in certain areas in the U.S. and elsewhere. The desert is pretty miserable when thinking of growing anything. Solar powered greenhouses can do a lot, and that is to provide for the proper lighting via LEDs, recycle water and provide the proper temperature for growth. Winters can get quite cold, near and below freezing. These greenhouses can regulate the temp by letting light in and keeping cold out, and provide a great growing environment for winter crops. I see this use of solar with growing food as a much better alternative to just having solar farms that renders the land useless. This is a very positive step to take.
Solar panels can't pick just the green light which is not used by the plants. If red is absorbed, then green and blue are absorbed, too. (That's because photon energies for green and blue are higher than photon energy for red). This is true for silicon panels. Maybe there are other materials with different absorption properties, but these would be too expensive. As far as I know, currently there is no viable alternative to silicon.
Plants use red and blue light to grow leaves and flowers, respectively (iirc; I could have that reversed). Green light is the bandwidth they don't use, which is in part why so many plants appear green to us; it's the color of light reflected back out to our eyes by the primary type of chlorophyl.
Well done for this video. In France, experiments are being carried out but mentalities and regulatory brakes exist as in your country. Yet the advantages that you describe do exist. Plus one that can make a difference, freeze protection. Our wine production was severely impacted this winter. Except on the test plot in the south-east of France ...
I love this system. We should definitely be doing it wherever and whenever possible. Governments need to give this the support it needs and chop through that red tape.
They should do this at abandoned shopping malls, as well. They have acres of parking lots baking in the sun. You could even put the solar panels on raised frames and park the cars underneath them.
Nice presentation! I can think of many high-value crops that could be grown this way - Strawberries, blueberries, asparagus, blackberries, table grapes (the equipment to harvest wine grapes is BIG, probably wouldn't work well), celery, broccoli, cauliflower. In my area (Upstate NY - Finger lakes area) we use very little irrigation and have many overcast days, so no great savings on irrigation water and probably reduced power generation from solar panels on many days. The break even point on this plan would be to produce enough income from power generation to negate the loss of income from farming activities PLUS the cost of hardware installation PLUS the maintenance costs. I'm sure that with the projected growth of electric cars over the next few years we will need expanded power generation everywhere, and the cost of electricity will increase with demand. I would love to see a pilot project in this area to determine the feasibility of this system. Of course any income generated from solar panels on dedicated farm land would have to be considered as farm income.
Solar should be reserved for areas that have no other use. When the companies come in to build these sites, they’re a lot more destructive to the land than they lead on. They don’t remove underground cables at the end of their lease. They bulldoze when they tell landowners they won’t and they threaten the neighbors to put their land into solar panels too or face a transmission line easement. You try farming land that had all of its topsoil pushed into the neighbor’s ditch to flatten the ground and see how well it goes for you. Solar is being pushed by utilities to keep themselves in control of the power supply. They’ve been lobbying the state governments to not require utilities to pay individuals properly who are net positive in energy usage. If they paid end users properly, we’d see many more individuals investing into putting panels on their roofs and yards. If we were to spread these panels out over buildings and building carports over places like Walmart parking lots (72,000 acres alone), we’d be putting the power where it is needed instead of creating a need for more large power lines sending the power hundreds of miles away. Solar has a big green label on it, but few people are getting out and seeing how it is being executed. Remember, an area of farmland the size of Iowa in the United States has been lost to development in the last 30 years alone. When will the push stop? Where does urban sprawl end?
Yes, unfortunately big solar is just the same as big power, because it is runned by the same people - people with lots of money. They have no interest in the green aspect of it - just the financial one. In Bulgaria for example: Government connected individuals wrote the laws to get preferential deals for themselves, created their big solar farms and then under EU pressure changed the laws back to ''normal' so now anyone who wants to build a farm is heavily punished unlike the already built farms that belong to the government mafia. Never mind trying to be forward thinking and trying out new things like in this video. We try to fight for things like solar on every parking lot, while big money only thinks about how to screw us out of every penny every chance they get. Being USEFUL is counterintuitive and unnatural to them. Because they are parasites.
I think it’s pretty cool that you can farm crops and also energy on same spot.. I’ve seen similar principles but in desert.. it could be solution for greening deserts 🌵
This is a brilliant initiative. If governments subsidise solar panels used for agrivoltaics it could provide incredible benefits as a way to use agriculture and energy production from the same limited space, and farmers can clearly benefit from allowing agrivoltaics if they match specific crops to their solar panel use and local environment. With land for agriculture being so in need, this could really solve two issues at once. Furthermore, with our climate getting hotter, solar panels could be used strategically (placed very high up) to shade and conserve water use by trees or even parts of forests. With wide and sturdy poles, they could also be used to shade these large grazing animals too. There are some great applications here.
I so appreciate this. Thank you. I wish California would consider agrivoltaics. It would save water we don't have enough, have too much of the sun, and the electricity we always run out of. Please keep up the good work.
I used to be a Site Manager for a 200MW solar farm in Mexico and had the goal to use sheep as an ecological way to cut vegetation. Unfortunately, locals and my company weren't too interested in that, but I still think is that this kind of interaction needs to be done.
Aside from having a slightly cooler and a little more shaded work area for farmers. Another big possible win to this is it could eventually lower the cost of produce in the store by lowering the cost of farming. Today’s farmers face high fuel prices that could be saved by switching to battery powered farm equipment. Farm equipment could be charged by the solar panels, possibly eliminating the cost of fuel all together. Another benefit of that is the cost savings on equipment maintenance as EV’s are known for having less maintenance over fossil fueled counterparts. Also there wouldn’t be the air pollution associated with fossil fueled equipment. The the plants are not only providing food, but also filtering the air. So not only would you be providing food and electricity on the same land, you’ll also be providing fresher cleaner air
Do you know how large a battery it would take to power a piece of farm equipment? We are 4-5 decades away from power storage efficient enough for that. The weight of the battery alone is enough to make it totally unreasonable because it would cause massive soil compaction. Not to mention the cost of the equipment, if a Tesla model Y is 100k tell me how much a tractor is going to cost? A million bucks? If a pickup EV isn’t capable of pulling a trailer even 80 miles tell me how a massive tractor is going to pull a massive piece of tillage equipment or a planter all day long? It ain’t happening anytime soon. The wasted time alone would be a huge cost to a farmer.
@@nickschaps4022 battery size depends on the size of equipment you are trying to run. You wouldn’t be operating huge combines in an area like this. It just wouldn’t fit. Ryobi makes tillers that run one 40v batteries that can easily be swapped out. Ryobi and ego both make lawn equipment that run on batteries that can be swapped out with fresh batteries once the batteries they are running on are depleted. Nobody said they had to have a battery big enough to run all day. Smaller equipment would be necessary for these more confined spaces rather than massive farm equipment used in big open fields. Batteries are getting better and better all the time as more demand causes more innovation.
@@nickschaps4022 honestly, I feel like with this type of farming, there will be more man power involved than big equipment. The use of small equipment will probably be much more usefully so battery powered sizable equipment wouldn’t be very far fetched
@@nickschaps4022 I think you can offset the battery weight issue with some dual purposing of the overhead solar canopy. Setup the canopy with electric feedwires like in a city monorail systems to act as the delivery system for the tractor, then the tractor can be more efficient by not carrying the battery weight. Hell, if you design it right you can fully automate an electric tractor to run along these wires under the canopy without a human having to control it.
I work at a CAFO that is less than a 1/4 mile from a electric transmission line. I think it would be a win win to install solar above the pens. It would make some shade for the cattle, and maybe offset our methane production somewhat. The cattle currently suffer during the summer with zero shade. Solar panels above the feedlot pens would give a duel use to the same area of land without any sacrifice.
The companies that build these projects want nothing but the best yielding crop ground. It’s the easiest and fastest way for them to build them. They get the added benefit of putting more panels in one place so the power stays utility owned.
@@kitemanmusic That is true, the cattle that would be potentially shaded by solar panels are still going to be fed a diet of corn though and fart out lots of methane, so they might as well have a little bit better life, at least in the summertime.
SoCal is a perfect location. This year for the first time I'm getting electricity credits while running AC whole day long. Thanks to solar panels installed last fall. The fact that LA didn't experience any power outages this year while temperatures hit all time records is a proof of solar panels benefit to the community in general. I will be super excited to see the synergy examples between agriculture and renewable energy production
I've thought about keeping chickens under panels for years. Panels would need to be taller(?), and the wires etc safe and hardened, but the chickens would have a roof on their run!!
I think the chicken tractors could be used with the solar panels roof. Land is regenerative sequstering carbon. Cattle and other livestock need shade structures, again some Mobile, some permanent. Also regenerative. If we can sequester carbon through this and it provides power win win. But it has to be well designed. I see no reason why some wind turbines be used in conjunction with this to improve grid reliability and lower costs. Either or is not a winner
This sort of farming would be greatly beneficial here in Australia where water can be a little scarce at times. Storms come through (hail) and wipe out large area's of fruit.. Grapes, pumpkin, corn, etc etc. Having this type of set up would help protect the plants whilst having other benefits. Water reduction, power production etc.. Fantastic idea.
I love the model of sheep grazing combined with solar panels; I think it could work extremely well with the rotational grazing model: a strip or block of panels will define the boundaries of each paddock in the rotation. It would be important to seed the right kind of forage on the soil under and between the panels, with plenty of legumes like trefoil in the mix. The panels themselves would provide much-needed shade. Ideally, the would supply power to electric perimeter fencing, to keep predators out.
Some things just make sense, and this guy certainly had an eye for spotting them. And he has the talent to create well constructed well researched, informative videos.
This is absolutely fascinating! I know the focus is on large-scale farming and energy gathering. However, I can't help but wonder if this couldn't be even more beneficial if the scale was minimized to households, city gardens, and the developing world! Better and more efficient land use is always positive and would be fantastic in areas where the urban spread is problematic, there are "food desserts', or extreme impacts on land uses due to infrastructure development and expansion.
100% much more efficient to produce the energy (on the spot where it is needed), like you say minimized to household sizes, gardens etc. Obviously though "farms" aswell would be needed, but in the end of the day. Basically any and every househould should become self sufficient more or less with solar & storage. It should really become mandatory for housing etc to include solar already at design stage for maximum output and clean design integrations. For an example we can already start making our whole housing walls etc in solar tiles. and that is just 1 single tiny part of the story.
For more than a year I have had this idea of combining a track that circles in time with solar movement (similar to circlular sprinklers of industrial farms) with fish/plant hydroponics below them slightly offset. Still requires lots of maths that I am too time crunched to do, and it wouldn't necessarily "make" extra electricity. But my dream is for them to be single kits that can be air dropped into extreme rural areas. Where they make enough electricity to maintain all of the fish and plant needs; along with the energy to move the rotating solar panels. A triple combo solar, vegetation and fish farming operation that doesn't need anything beyond water and maintenance. Go ahead and take the idea, I won't ever get around to designing or patenting it. I only ask that you actually try and make the airdrop thing a thing, too. -Your Friendly Neighborhood Druid
YES!!! Thank you so much for doing this video. I’m studying Agrivoltaics in my Master’s program right now. I’m looking at geographical political economy under agrivoltaic energy transitions. I’ve found thus far the people-component of permitting agrovoltaics is extremely challenging, but do-able!!
This can absolutely be tapped into. A very good opportunity for both developed and developing countries. In addition to the point of solar production, wouldn't dry and arid regions with a higher rate and concentration of sun solve this issue? I understand that there is more space in between the panel sheets; although using mono-crystalline panels might keep that production at normal levels.
Another regenerative farm/energy synergy would be small scale pumped hydro. A lot of farmers already have solar here in germany and quite a few have irrigation ponds. If it werent for regulations it would be super easy to connect two irrigation ponds at different elevation and store some of the excess energy for nighttime use. If its a big farm with enough land a bigger irrigation pond could supply the neigbours with power as well. Basically paying the farmer for storage could create good effects for village sized micro grids.
One thing rarely mentioned is that not only can plants get light saturated, PVs can convert 10x-20x the received light. If the plants are then saturated by chlorophyll-optimized LED grow lamps, the PV density could be raised to the same as a normal solar farm. The reduced water usage also reduces the amount of nitrate fertilizer needed, as less gets washed away by irrigation.
In New Zealand, this technology is being used on five solar farms mainly in the country's North Island that are operated by Lodestone Energy. The company lease land from local farmers who still can use the land for farming. It is a 'win win' for the farmer, as they get income from the farm and from the solar farm lease.
A very smart idea! Another problem I think you missed would be how to connect these farms to the energy grid. It is unfortunately so that you cannot introduce a large amount of energy to a certain area of the grid if no-one will use it, or the grid is not sophisticated enough to handle the amount of electricity. Sadly, the electricity grid out in rural areas are often not well developed and this development introduces a further cost to the agrivoltaic system :(
I don't see that problem in Europe. Population density here is very high here and wind turbines are also popular so there is a way to integrate them into the grid, especially in Germany. In the US I could imagine it being to rural in some places but Texas also somehow found a way to integrate lots of wind turbines.
We should use the right tools for the result we are looking to obtain. In this case study, it was a better crop yield and lower operational cost to the farm on top of generating some energy where it would have generated none before. This model may not fit everything so it doesn't have to be used everywhere. It should be used where it makes sense. That said, I personally, think it's a great use of space to maximize its productivity.
India is building huge solar plants on arid/waste land, even taken on rent from farmers. Indian States are pushing urban roof top solar plants. Indian Govt is enticing farmers to go in for 50% subsidised Solar water pump which after watering fields the solar juice feeds the grid for additional income. Before holier than though talks, I fixed 9kw and 10kw roof top grid connected solar plants - no bills for last year. But always wondered about the land usage beneath solar panels. Agrivoltaics is a superb idea but needs more research in the factory and on the farm. Once economic benefits are Visible to Indian farmers it will trigger the next Green Revolution of India.
The solar panels can also be used to collect condensate water or due that collects on them. This will be fresh water in most cases. The reduction to need for water in the arid regions is a far greater advantage. In inhospitable regions fodder crops can be grown in waste containers under the solar panels.
Excellent video, Matt! I run a few subs on Reddit and have been sharing your vids over there. I also teach people how to install small off grid solar and build sustainable and affordable housing.
Damned good video! I've been advocating and thinking about this since 1968! Our So. TX farm was often too dry to grow Maiz or grain. I advocated stringing solar panels on wire rope or steel cable to suspend the panels above the ground and allow the tractors to get to the ground. Less water evaporation and regulated solar exposure would maximize production. Plus eventually there would be electric tractors. But who is going to listen to a 14 yr old!
Solar photovoltaic technology is really starting to play a role in various industries, and I am glad to see this. It is a very environmentally friendly energy source👍
Solar Panels plus corals? The ability to control sunlight intensity on some nearshore coral reefs may be another application of this technology that is a win-win. Researchers, such as Scott Condie, are currently investigating what amount of shading is beneficial for corals that experience thermal stress. The Undecided video collection is such an excellent video series on current technology!
I think this is so important and impressive that it shouldn't matter if you have to make small sacrifices. It's especially easy if the farmer owns the solar panel or has a fixed interest rate. But even for the raspberry farmer who needed a weather shield anyway it is a benefit. I think a lot of time and thought should be put into the building of these but that they are so efficient for land use its actually crazy. Imagine doing this on city rooftop greenhouses on every building sturdy enough for it.
Great project, I hope that some day most of farms will dual use of land, I have 5 acers of land at my home country (Jordan) and you gave me a great idea, thank you
Very interesting video. I am currently working on those projects. I would like to mention that a very crucial element of those systems are the sun trackers. Installing panels with sun trackers on those systems except from increasing the energy yield will lead to a decreasing of the structural cost. This would be resulted from their ability to change angle when needed so in cases of strong winds, they can be set to move horizontally so they will add less stress to the structure. (elevated panels are expected to face stronger winds so an installation with fixed tilts will need stronger supporting structure)
while trackers are great for increasing yield, they are also mechanical parts and those tend to fail. I've studied many cases where the trackers failed 5-10 years out. Solar panels are getting so cheap and better a capturing at various angles - that the necessity for trackers diminishes. You can just have you field divided into sections with different fixed angles and over panel your inverters - easier and more reliable then trackers.
Been investigating Hydroponics and Areoponics with a similar pull in mind, adding Solar panels near the greenhouse for that with some shade loving plants underneath sounds like a great option to get more green goodness for the money spent
well-made video about a very important subject. In very sunny countries, there is an increasing trend for covering plantations with nets to reduce exposure to direct sunlight to improve fruits quality. However, PV panels installation poses a risk that is overlooked many times. the panel changes the rainfall micro-distribution and on sensitive soils, it may accelerate soil saturation and soil erosion. Considering the increasing intensity of rain events, it might require re-thinking of the design and risks management.
This is an awesome idea, especially as we are struggling to transition into electric motors, I think if these agrivoltaics were turned into electric charging stations farmers would be more encouraged to set them up.
Perhaps agrivoltaics could help cultivate desert regions, with the solar energy powering atmospheric water harvesters. (Or ocean floating farms with powered desalination??)
This. Ocean farms need to be explored more. Depending on the produce, it could work with a reverse osmosis system. And besides solar, there's electrokinetics. Harvesting energy from ocean currents would be a bonus.
How in ocean floating farms, insects can go in and pollinate? Unless you are farming genetically modified seeds? Don't try to make fools of the viewers.
Fascinating. I'm thinking of ground-mount solar for my home. I have a perfectly south-facing hillside in my large backyard. I'd like to expand my bit of terracing and to more gardening on the hillside. Since my electric use is pretty steady throughout the year, it'd be best to optimize the panels for winter production, which means production would be low in the summer, but close to matching winter production, so it's okay... no, that'd be perfect. Because of winter optimization panels will be steeper than 45°. And of course to set the panels so lower rows don't shade the rows further up the hill, they'd need to be spaced apart. Like that berry farm in the video, I too have hail problems. So perhaps something like hardware cloth between the rows of panels could be a real crop saver. The increased expense will be only getting 2 posts from a 20-foot long steel pipe, rather than 4 (panels mounted high). And the extra cost of hardware cloth vs something cheaper like shade cloth (because I need more sun to pass through). I have not terraced my hillside yet. I suspect I could optimize placement of the panels so in the summer they spend part of the day shading the stone walls of the terrace and not the crops. It could work. I'll have to do a bit of engineering.
This system of programmable adjustable pvs is proving interesting for high value crops such as vines in top of the market wine areas of France. Given that in SW France we've already gained 1.4°C temperature, I expect to see more of these apvs installed over the next 5 years.
@dannyblast3392 would it, though? I'd rather be able to get underneath the panels than have them bolted onto a shingled roof, like a residential setting. As long as they're high enough not to conflict with plant growths, I don't see much of an issue.
i just gotta say i love you man, i dig every single one of your videos and its a pleasure to see you grow. Peace Edited after watching video: and i forgot to say one of things i like is the way your present it: straight to the point, fitting a 45min documentary in a 15min format with the added je ne sait quoi and fun included. thanks, ill have some more of that!
This is so great what you can do with the PV. I work as a climate change person for a community. They want to build a PV plant soon. After what I have seen I'd highly adovocate this. Maybe local farmers can be motivated to do engage in PV-agriculture. But in Germany they also want to put PV on bogs. Since they are so rare in our anthropocene I would loathe using bogs for PV.
I remember that when I was a child most of the emphasize on solar energy was about panels used to heat water with sunlight. Of course, since they were using direct sunlight their efficiency in warming water was higher than obtaining electric energy from sun and turning it into heat again. I was wondering that why don’t we use a combination of both solar panels which make electricity and solar panels which heat water on the home roof? The sunlight can primarily be used to make electricity and since only almost 20 percent of the sunlight energy is turned into electricity, the rest which turns into heat can be used to warm water which passes through tubes beneath the electric solar panels and is in direct touch with them to absorb the heat. By this way the temperature of the electric solar panels will also be reduced by the heat absorbing tubes filled with water and this will always keep the efficiency of the electric solar panels high.
As with all great ideas!... It's already been invented. They are still in development/new, but they work just like you describe. A photovoltaic solar cell on top to produce electricity, with conventional solar tubing directly attached underneath to heat water. Only a portion of the roof would need to be covered by this type of combo solar panel, because you can only use so much hot water.
i think this is the real solution to solve the food crisis and environmental issues in the same time. It may not be worth from the perspective of the investor but this will give the people more food, more clean energy with less pollution => very sustainable 😊
This channel usually provides a bit of hope to me which I appreciate. I really hope things like this can become profitable because things still aren't bad enough for people to simply do things because it's the right thing...
That's one of my biggest concerns in general. Until things can be justified cost-wise, it's hard to get everyone on board. Hopefully costs around this continue to drop.
@@UndecidedMF One thing that would be great would be to have a financial analysis of this solution. I’m thinking a spreadsheet breakdown so we know where the math doesn’t work. Financially, if look at farming it has irregular crop yields year over year. I see similar for PV energy production. However, I wonder if on average over a 20 year period the PV’s would be paid for (past BE point) and producing “free” electricity / profits from PV array. Similarly, I’m curious what percentage of the time the crop yields would be lower than traditional farming. I have to imagine having structure over the crops would make the yield slightly more predictable and consistent as its protecting from some of the harsh elements. Lastly, if we combine smoothing out the volatility and PV profitability in later years what would it mean to the farmer’s ability to get better long term interest rates for capital required to run the farm (i.e. it becomes a potentially better investment for the banker). Thoughts?
Hi Greg, wonderful point. We have implemented rain water harvesting along with vegetable production in green house integrated with semi-transparent PV panels with different packing factors and the results are promising. check out this video for now, we will soon come out with final video.
They do have some hydro panels out for commercial sale currently that you can find but I’m not sure they have been efficiently paired with farming yet?
I have seen it done before, the water was harvested and used to support a fish pond. The fish pond produced ammonia from waste then bacteria cycles the ammonia into nitrate and phosphate which is used as nutrients for the farm. (They also sold the fish which I believe to be tilapia….although I have absolutely no doubt that trout would be a better substitute for our markets and just as good at the above)
That would work only in green house or semi-greenhouse with drip irrigation. Horizontal panels decreasing evaporation from soil that is unrelated to plants may be enough
Matt, what I love about all your videos, especially ones that discuss the contentious space, it's your willingness to put forward the pro and con argument, all in the same segment. The contest of ideas and the debate in the discussion, is the only thing that will move us forward as a civilisation and society. Thank you for the videos mate 👍
But what do you think? Should we be trying to use agrivoltaics everywhere? Are there any other dual use renewable energy examples that you know about? If you liked this video, be sure to check out 28,000 Year Nuclear Waste Battery? Diamond Batteries Explained ua-cam.com/video/VWwKqSzakYU/v-deo.html
These communities that are pushing not-in-my-backyard issue are lucky they have word in edgewise because in Native communities and in minority communities when they put chemical plants in those communities they do not have the ability to say no.
I still want to see kinetic energy capture used as borders along farms and in high-wind zones...
To Rob the writer,
The water use statistic 0:13 for the livestock is a bit disingenuous, for example most of the water that the livestock drink does double duty since it also irrigates the grass grazing land (which IMPORTANTLY is usually low quality land Not suitable for crop production in the first place)
I'm wondering if it would be more cost effective to have a solar-powered-multi-level-vertical-hydroponic-farm-warehouse built on the same land rather than an agrovoltaic? What's the most amount of food that can be grown, harvested, and shipped for the least/most efficient amount of energy in 1 square meter? (Big brain time. Lol.) Cheers!
Add electric tractors, farmers could eventually cut the cord to big oil.
In India, we do something like this by placing solar panels at the top of canals. Because there are lots of canals in India. The extra benefit is solar panels reduce the loss of water due to evaporation providing extra for agriculture. The shade also prevents the growth of algae in the water. And the presence of water underneath keeps the panels cool.
500 iq
Awesome. Thats a fantastic play.
Started this already in some parts of Rajasthan n Haryana
Solar canals! Nice. I thought UC Merced was the only group leading the idea of solar canals.
yes,if no flood
As a Dutch Greenhouse Manufacturing Engineer I can already tell you that we calculate the steel constructions with the posibility to directly or later install solar panels. This means that when the end customer wants to place solar panels he can do so without any repurcussions from the local governments as the building permit and the construction calculations are already in place for any eventual agrivoltaic farming. But your story has enlightened me in a few more ways so thank you for that!
amazing can i have some of those design layouts i want to pilot this on our small land
great
Does your company have a website?
Thanks for the good news (news for me, not news for the Dutch). Big players on the food market will drive this development.
Here in Germany the NIMBY mentality is a big problem and I doubt that forward-looking engineering like this would have any chance for approval by decision makers.
The video is incredibly well done. Channel subscribed.
Germany needs to fucking learn from the Dutch. Ampeln...agriculture...bike lanes.
Sunny California with it's water shortages comes to mind for this. Saving 50% water costs, adding income from power generation and maintaining same yield - a win-win.
If Americans will do these things then who will bomb countries and bring peace.
I’ve seen California crops under plastic tents. We should try replacing some of this with solar panels. California’s desire to promote solar power should be compatible with this.
Yeah
yes, and there's also the opportunity to tailor the solar panels to light frequencies that plants don't prefer. With semi-transparent panels allowing the light through that plants like the most, we can make up the energy production shortfall caused by currently being forced to space the panels out (like on the raspberry farm).
@@pradeepkharta5953 That, sir, is an important question that the psychopathic corporations, who make trillions from wars, would prefer people to ignore.
To me agrivoltaics seems to be most effective in smaller operations where heavy machinery isn't used. The raspberry farm was a perfect example of that. Basically if it grows in a plastic tunnel and it's harvested by hand, agrivoltaics will probably be perfect.
clearly you have never seen a commercial Raspberry Farm
wonder how much those strawberries will cost adding the cost of the solar pannels to the price :)
You can just put the solar panels on wheels like they already do with watering equipment probably
@@mcsanad That depends on who owns the solar panels. If they are owned externally then it probably wont affect it at all. If the farmer owns them, it possibly could, but then the higher guarantee on yield means less waste, the shade means less water usage and the electricity needed by the farmer would come from the panels and not the inflated grid prices. So it could offset the installation costs.
@@Ben.Royals well from my point of view planting strawberries on fertile land under solar panels might be a great source of power but the money you lose out on by not planting crops is really unequal. If, the panels are owned by the same person that manages and sells the strawberries and they'd like to cover the cost of the panel, it'd either take them multiple lifetimes to get the price back or to sell the strawberries at a super high price. This idea was obviously made by someone who has never done agricultural planning or work.
Instead, putting solar panels on your rooftop, perhaps vehicle hangar or even a barn covers around the same area if not more. This way the farmer is independent from the grid and had more land to cultivate with and make bigger profits than he ever could with measly strawberries. Oh and I forgot to mention, this way the price of bread and other products that come from agriculture won't rise so you get to buy your daily bread for an alright price instead of buying strawberries with sky high prices.
I say this is the best possible use, not wasting any fertile land and still getting their own power :)
Yes we should, I’m trying to learn as much as I can about it to try it on my farm.
Let us know how it goes! 🤙
@@KLRJUNE As we say to soldiers, Thank you for your service.
Best of luck... remember you have to compromise (optimize...???) between food and energy production .. depending upon where/what you farm and Solar Generation...If "up north" maybe a fully enclosed AV System could/would provide 12 month growing season in a Greenhouse like environment... and remember as you "grow solar electricity" too you can provide heating too (use heat pumps that have a COP of 4+ ... COP=HeatOut/Heat In)..
Farmers in Georgia are now growing cash crops that in the past would just burn up, but with the mix of daily sun and shade they are growing crops with a higher cash value than just peanuts and onions.
@Angie Mead King I hope someday, I can visit your farm. Nag-aaral ako dito sa Canada para maging mas efficient at responsible farmer sa atin. I love what you're doing there. Ingat! :)
I have a home garden/homestead in the desert and I'm constantly having to use shade cloth to protect my crops. Even sun loving crops like peppers can get burnt to a crisp if it gets particularly hot and bright. I'm legit considering trying to slap together a home setup like this.
love you 😘
Why grow a garden in the desert, the fresh water costs are high, a resource we are fast running out of.
That is SO exciting! You posted this 3 months ago. I hope you'll update us on your progress. I'm about to move f/desert, where we've been getting 11"rain/year, to a one acre, unimproved homestead that gets 56"/year. I hope to slowly put in a no-dig, permaculture garden system. Although water will not be a problem, I think the challenges of excess sun and affordable energy are problematic everywhere.
@@HeloisGevit yeah no , just nuke us already
@@HeloisGevit More than one billion people on Earth live in deserts. In addition, many grasslands and even forests are desertifying due to extreme drought and intensifying heat. There are many food producing plants that are heat and drought tolerant, so we can grow food locally in arid climates but we still need to adapt to environmental factors in the way we grow food. I live in the Sonoran Desert. I have a food forest in my backyard. In addition to improving the soil and cleaning the air, it adds moisture to the air and keeps the temperature lower in summer and higher in winter. With ground-level irrigation I use less water to keep everything going than the neighbors who have no plants at all but wash cars, let the kids play with the hose, or have a pool. My water bill is lower and yet I have groceries growing year round. Growing in the desert improves the local environment, provides nutritious local food, and encourages more rainfall.
I wish that instead of the "car broiler" top deck on parking decks in urban areas, the top deck would be covered with solar panel for shading cars & people, as well as generating electricity. This could be beneficial for powering more charging stations in the deck.
That's really a no-brainer... makes total sense
Yep and all supermarket and airport carparks, car hire lots etc
I've been thinking about canopies above parking lots for some time - not just the car broiler either. Think about the acres of parking in front of the grocery store - what if it were covered with solar canopies? Grocery stores use a ton of electricity for the HVAC and refrigeration units, even if they never generated enough to sell to the grid, they could radically offset their own load.
@@leifhietala8074 The issue is the support pylons. If the structure isn't self supporting then the poles discourage people (especially with trucks) from shopping there. Those panels and mounting are HEAVY. Notice in this video they optimized for tractors in one direction only.
One local grocery with underground parking has a LOT of spaces with concrete pylons where doors open. I would say about half of the parking spaces are comfortable to use for most drivers.
(it is a 12 story apartment building on top of that structure) The apartment parking is in the pedestal so far less "support" needed.
@@leifhietala8074 The parking lot at my local community college has solar canopies. And the elementary school has a tall one which adds shade for the kids to play under.
There are also new solar panels that allow the wave lengths that plants need to go mostly through the panel. This would be ideal for greenhouses as they already have the metal frames.
Hey, late question to your comment, but do you know the company that is creating this product?
Glad to see a SMART application of solar on land that does not waste the land underneath. The shade the panels produce should be optimized. Parking lots, the building underneath in hot climates

@@Slebonson Smart
I think it's possible to make strings of solar diodes instead of light blocking panels.
@@Slebonson Been to Disneyland (Paris) a few weeks ago they where doing the same to their parking lot near the main gate (was still in the early stages of construction tho)
This seems important. For me the measure is the production of two hectares of agrovoltaics, compared with 1ha of traditional agriculture and 1ha of normal photovoltaics. I like the idea that panels can produce electricity and at the same time produce useful shade.
I can imagine Agrivoltaics making big strides in the future. I feel like right now it's just in its starting phases like many other green energy production ideas, but maybe once more research has been done and the benefits of using agrivoltaics is better demonstrated and documented, it can really take off.
Although I did not know the concept existed I imagined it and went searching for just this idea. I searched ‘can you grow under solar panels?’ and was VERY PLEASED to find this video on agrivoltaics!!!! Thank you for this beautifully explained video. We are building a home in Jamaica and I was saddened by the builder’s plan to create a solar park which would use up so much of the precious land space (a slope that has to be terraced) that I had plans to create garden spaces. I wish you were closer to Jamaica so I could actually see the agrivoltaics in person. Thanks again for this video!
Helped conduct research at the University of Arizona on agrovoltaics! All of the crops under solar panels produced significantly more, because of the reduced heat stress. The greatest difference was the tomatoes, as the control group in the sun didn't fruit at all so the percentage increase in yield was a problematic way to summarize the results as we were dividing by 0.
Then it was not properly designed experiment. No one in that climate would try to grow tomatoes without shade cloth.
Sheesh
@@Matt-dc8lp solar panels maybe replace shade cloth? and I don't think Matt really provided enough details on the design of the experiment for you to dismiss it without asking for more clarification
Yeah reduced heat stress as in direct sunlight, other wise the covering panels gather and radiate heat into the atmosphere adding to the heat island effect. Less CO2 produced maybe but definitely heating the local atmosphere. Doesn't CO2 do that already?
Why dont they use mirror to reflect sunlight for crops from sides... Dont say they cant lol.. 😂
I've been interested in Agrivoltaics for the past 2 years and I still learned new things from your video. Thank you Matt! Another excellent video!

3. Solar panel over agriculture water canals
4. Solar panels over the hydroponic, aquaponic, or aeroponic farm. Use of grow lights may be needed.
5. Solar panel over cattle shelters
6. Solar panel over building structures
In Pakistan, we have a project underway to put floating solar panels over water dams. Makes the surface area usable, reduces water evaporation and helps keep the panels cool and I don't know the technical details but somehow it also helps improve the efficiency of panels too (in terms of generating energy per unit).
They're producing more because they're double sided (water refletion) and the cooling also helps
@@ARC_CONTROL
Solar panel efficiency is higher at cooler temperatures. That’s just how the silicon works.
As an agrivoltaics developer I very much appreciate this content. Super high quality video. Thanks!
Fish pond covered with a PV installation. PV panels shade the water, reduce evaporation and keep the water cool, while the remaining water evaporation cools the PV panels.
Sounds eFISHient.
@@someotherdude now that's a GOOD ONE!! XD
not only fish ponds, but open water storage resevoirs
Floating solar is more expensive to clean and more prone to bird 💩
It's easier to let sheep graze under the panels
Matt, it seems like, with some research, this could be a win-win for both energy and crop production. I saw somewhere that people were installing solar panels over canals. The panels reduced evaporation of the canal water, and kept the underside of the panels cooler, increasing efficiency.
Heard of that in India.
Do you mean irrigation channels? How could barges use such canals? are the panels very high over the canals to allow boat traffic?
@@nct948 I suppose sailing boats (with masts) wouldn't use the canals, so the panel are mounted maybe 2-3 meters above the banks, to clear the boats. I guess they figure this out before they build them ! Maybe what I saw was actually irrigation channels (rather than navigable channels).
They should do that here in az over the aquaducts. Would be perfect to minimize evaporation and generate power. No boats of any kind are allowed in the aquaduct anyway. Perfect solution.
Veritasium did a video about a California water supply putting plastic balls into their reservoir, I imagine putting solar panels over it instead could actually do quite a bit of work out there. Providing energy for the area, preventing birds from getting near it (he explains why it's an issue in the video) and reducing evaporation would actually save them loads of money in regards to water. Though, I'm sure the repairs and installation likely wouldn't be as cheap as building this same system over land, since they'd need to put supports in the middle of the water.

This is just the video upload that I needed. I have a roof top garden, and I was looking for space to install a solar plant for my house. Your video has given me a totally new perspective. Now my mind has started working.
Several decades ago some articles were written about the potential benefits of putting farming equipment on rails in order to not compact the earth under the wheels. At the time I recall the major advantage as being reducing the energy consumption of the equipment while working the soil. Guiding the equipment through the rows between the solar arrays effectively achieves this goal. Furthermore, the structures could provide attachments for a hot shoe or catenary power takeoff to power electric equipment without the need for large battery packs. I believe fuel is a significant cost for farmers. Reducing the energy cost to the farmer could be further justification.
Yeah, powering the machinery itself would be ideal, and selling off the surplus as a bonus.
@@UncleKennysPlace There is nothing to stop farmers doing this in any field. It's just not cost effective
Agree. APV gets even more interesting when you further utilize the overhead structure to distribute power allowing the farm implements to be electrified. As we move towards decarbonization, fossil fuel use in industries like agriculture will need these solutions!!
@@daubentons1 I think you are well on to it- the original poster had no budget to pay for the rails, cross ties, maintenance- or the connector rails needed to get from one field to another. Same thoughts occur to me for farm equipment powered by direct take of from the overhead PV grids. But good thoughts to start from! FR
Over the long run it probably is better. But there seems to be significant initial cost that would keep anyone from doing that without federal assistance.
As a homestead and hobby farm, this video is great information for us to branch out. Thanks for your dedication on bringing info to the hungry masses.
As an employee of a company that operates of some of GroenLeven's solar park portfolio, seeing a pilot project of theirs so close to home featured in this video was a very pleasant surprise! For anyone who wants to know, there are currently more Dutch shade-crop farmers installing solar on top of their greenhouses (not as a pilot, but as actual revenue generating projects). Driving through the vast greenhouse landscape north of Amsterdam and The Hague you can see many of these popping up, great development to see :)
This doesn't surprise me to be honest. With the dutch farmers fighting for their land and Russia cutting off oil, they definitely need a little bit more self-sustainability/cost mitigation.
Bi-facial panels mounted vertically on stilts.. Thank you very much for the idea.. We are embarking on a project integrating solar farm with existing aquaculture. We thought the runaway commodity price has torpedoed our dream.. Once again, thank you very very very very much
I have the hobby to recommend sci-youtuber to science-fans.
I'm often called random or even robot for that, but whatever. I keep going for those few
that say 'Yes thanks'.
Vertical bi-facial panels are not very wind-resistant... Please, keep that in mind.

The dual use aspect reminds me of trials with floating solar panels, over water reserves and canals with no transportation, to harvest energy and reduce evaporation in hot climates.

When it comes to future technologies this is without a doubt one of the most interesting and accessible channels on UA-cam. Thanks for all your work and research Matt
Hello Matt, now that I'm retired, my plan is to give hydroponic farming a try. I was concerned about the world getting hotter. In NJ the past summer was unbearable.
I love the thought of combining these 2 products. It is a win-win for everyone.
Last week, I went to a farm. I saw that they used grape vines over a chicken coup. They said that this was a win-win for the past few years. Why buy chicken waste !
I found this fascinating .
Keep up the great work !
This is something I've been thinking a lot about recently. Really love the concept. It turns something which is a liability and turns it into an asset.
I saw this a few years back at the Biodome in Arizona as a study, it help ed keep temperatures way lower for the plants in arizona's aggressive heat, and helped growth all around.
I love how you wrapped up your thoughts on PV Farming at the end. Really well put on all the challenges faced. Also, Just Have A Think is such a good channel for Climate issues. This may be my favorite episode from you yet Matt!
So glad to hear that! Just Have A Think is a fantastic channel.
It's not farming idiots it's a scam morons they take your property to fill with Soler shit and there goes are live stock
@@Wildwood56 I disagree. Do you have any evidence to back your claims?
It would be interesting if a solar panel could be made red to let through the light the plants mostly use and absorb the light they don't need.
good idea (understandably what's shown here is testing and proof of concept) rather than use traditional mass produced panels that would go on the roof of my house, they should create a bespoke/optimize panel for this use case. 6:40 - like the "strawberry panels" shown with more spacing for light transmission, i suspect somebody somewhere is working on what you propose for a 2nd/3rd phase test. the results so far seem promising and could be even more so with some "tweeks". #POTATOPANELS , #TOMATOPANELS
@@nateman10 I've seen a couple of videos about solar greenhouses. This can address a number of problems in certain areas in the U.S. and elsewhere. The desert is pretty miserable when thinking of growing anything. Solar powered greenhouses can do a lot, and that is to provide for the proper lighting via LEDs, recycle water and provide the proper temperature for growth. Winters can get quite cold, near and below freezing. These greenhouses can regulate the temp by letting light in and keeping cold out, and provide a great growing environment for winter crops. I see this use of solar with growing food as a much better alternative to just having solar farms that renders the land useless. This is a very positive step to take.
Solar panels can't pick just the green light which is not used by the plants. If red is absorbed, then green and blue are absorbed, too. (That's because photon energies for green and blue are higher than photon energy for red). This is true for silicon panels. Maybe there are other materials with different absorption properties, but these would be too expensive. As far as I know, currently there is no viable alternative to silicon.
Plants use red and blue light to grow leaves and flowers, respectively (iirc; I could have that reversed). Green light is the bandwidth they don't use, which is in part why so many plants appear green to us; it's the color of light reflected back out to our eyes by the primary type of chlorophyl.
That already exists. Search window see-through dolar glass windows.
Well done for this video. In France, experiments are being carried out but mentalities and regulatory brakes exist as in your country. Yet the advantages that you describe do exist. Plus one that can make a difference, freeze protection. Our wine production was severely impacted this winter. Except on the test plot in the south-east of France ...
Some hail protection would occur too - though, of course, the panels themselves should be able to endure it too
I love this system. We should definitely be doing it wherever and whenever possible. Governments need to give this the support it needs and chop through that red tape.
They should do this at abandoned shopping malls, as well. They have acres of parking lots baking in the sun. You could even put the solar panels on raised frames and park the cars underneath them.
Great idea, nobody wants their car to become baking hot in the sun anyway
@@nocensorship8092 this is done on the parking of disneyland paris
You are genius
I expect we’ll see a lot of parking lots covered in solar panels. It makes a ton of sense.
Nice presentation! I can think of many high-value crops that could be grown this way - Strawberries, blueberries, asparagus, blackberries, table grapes (the equipment to harvest wine grapes is BIG, probably wouldn't work well), celery, broccoli, cauliflower. In my area (Upstate NY - Finger lakes area) we use very little irrigation and have many overcast days, so no great savings on irrigation water and probably reduced power generation from solar panels on many days. The break even point on this plan would be to produce enough income from power generation to negate the loss of income from farming activities PLUS the cost of hardware installation PLUS the maintenance costs. I'm sure that with the projected growth of electric cars over the next few years we will need expanded power generation everywhere, and the cost of electricity will increase with demand. I would love to see a pilot project in this area to determine the feasibility of this system. Of course any income generated from solar panels on dedicated farm land would have to be considered as farm income.
Solar should be reserved for areas that have no other use. When the companies come in to build these sites, they’re a lot more destructive to the land than they lead on. They don’t remove underground cables at the end of their lease. They bulldoze when they tell landowners they won’t and they threaten the neighbors to put their land into solar panels too or face a transmission line easement. You try farming land that had all of its topsoil pushed into the neighbor’s ditch to flatten the ground and see how well it goes for you.
Solar is being pushed by utilities to keep themselves in control of the power supply. They’ve been lobbying the state governments to not require utilities to pay individuals properly who are net positive in energy usage. If they paid end users properly, we’d see many more individuals investing into putting panels on their roofs and yards. If we were to spread these panels out over buildings and building carports over places like Walmart parking lots (72,000 acres alone), we’d be putting the power where it is needed instead of creating a need for more large power lines sending the power hundreds of miles away.
Solar has a big green label on it, but few people are getting out and seeing how it is being executed. Remember, an area of farmland the size of Iowa in the United States has been lost to development in the last 30 years alone. When will the push stop? Where does urban sprawl end?
Though provoking points here - perhaps a future Undecided video?
We need a video about everything you mentioned.
Interesting read.
However: Citation needed.
Yes, unfortunately big solar is just the same as big power, because it is runned by the same people - people with lots of money. They have no interest in the green aspect of it - just the financial one. In Bulgaria for example: Government connected individuals wrote the laws to get preferential deals for themselves, created their big solar farms and then under EU pressure changed the laws back to ''normal' so now anyone who wants to build a farm is heavily punished unlike the already built farms that belong to the government mafia. Never mind trying to be forward thinking and trying out new things like in this video.
We try to fight for things like solar on every parking lot, while big money only thinks about how to screw us out of every penny every chance they get. Being USEFUL is counterintuitive and unnatural to them. Because they are parasites.
@@fast-yi9js all personal stories. But I’ll be happy to make a video talking about this.
I think it’s pretty cool that you can farm crops and also energy on same spot.. I’ve seen similar principles but in desert.. it could be solution for greening deserts 🌵
This is a brilliant initiative. If governments subsidise solar panels used for agrivoltaics it could provide incredible benefits as a way to use agriculture and energy production from the same limited space, and farmers can clearly benefit from allowing agrivoltaics if they match specific crops to their solar panel use and local environment. With land for agriculture being so in need, this could really solve two issues at once.
Furthermore, with our climate getting hotter, solar panels could be used strategically (placed very high up) to shade and conserve water use by trees or even parts of forests. With wide and sturdy poles, they could also be used to shade these large grazing animals too. There are some great applications here.
I so appreciate this. Thank you. I wish California would consider agrivoltaics. It would save water we don't have enough, have too much of the sun, and the electricity we always run out of. Please keep up the good work.
I used to be a Site Manager for a 200MW solar farm in Mexico and had the goal to use sheep as an ecological way to cut vegetation. Unfortunately, locals and my company weren't too interested in that, but I still think is that this kind of interaction needs to be done.
Nice sharing from you, may i have a chance to get your experiences in solar farm projects - thanks
Did you give up after just one try? Perhaps, pollinator fields or crops that like some shade during the day could be a solution.
Hello Sir, can I Dm you to learn about Agrivoltaics
I know that plants can help keep the panels cooler so they stay in their optimum operating temperature range.
This should be mandatory, there should be laws to enforce this rather than laws that prohibit agrivoltaics.
@@jagattikhan6965 nothing should be mandatory
Aside from having a slightly cooler and a little more shaded work area for farmers. Another big possible win to this is it could eventually lower the cost of produce in the store by lowering the cost of farming. Today’s farmers face high fuel prices that could be saved by switching to battery powered farm equipment. Farm equipment could be charged by the solar panels, possibly eliminating the cost of fuel all together. Another benefit of that is the cost savings on equipment maintenance as EV’s are known for having less maintenance over fossil fueled counterparts. Also there wouldn’t be the air pollution associated with fossil fueled equipment. The the plants are not only providing food, but also filtering the air. So not only would you be providing food and electricity on the same land, you’ll also be providing fresher cleaner air
Do you know how large a battery it would take to power a piece of farm equipment? We are 4-5 decades away from power storage efficient enough for that. The weight of the battery alone is enough to make it totally unreasonable because it would cause massive soil compaction. Not to mention the cost of the equipment, if a Tesla model Y is 100k tell me how much a tractor is going to cost? A million bucks?
If a pickup EV isn’t capable of pulling a trailer even 80 miles tell me how a massive tractor is going to pull a massive piece of tillage equipment or a planter all day long?
It ain’t happening anytime soon. The wasted time alone would be a huge cost to a farmer.
@@nickschaps4022 battery size depends on the size of equipment you are trying to run. You wouldn’t be operating huge combines in an area like this. It just wouldn’t fit. Ryobi makes tillers that run one 40v batteries that can easily be swapped out. Ryobi and ego both make lawn equipment that run on batteries that can be swapped out with fresh batteries once the batteries they are running on are depleted. Nobody said they had to have a battery big enough to run all day. Smaller equipment would be necessary for these more confined spaces rather than massive farm equipment used in big open fields. Batteries are getting better and better all the time as more demand causes more innovation.
@@nickschaps4022 honestly, I feel like with this type of farming, there will be more man power involved than big equipment. The use of small equipment will probably be much more usefully so battery powered sizable equipment wouldn’t be very far fetched
@@nickschaps4022 I think you can offset the battery weight issue with some dual purposing of the overhead solar canopy. Setup the canopy with electric feedwires like in a city monorail systems to act as the delivery system for the tractor, then the tractor can be more efficient by not carrying the battery weight. Hell, if you design it right you can fully automate an electric tractor to run along these wires under the canopy without a human having to control it.
Thankyou, it makes emminent sense. There are translucent solar panels that let through about 30% of incident light, similar to greenhouse glazing.
I work at a CAFO that is less than a 1/4 mile from a electric transmission line. I think it would be a win win to install solar above the pens. It would make some shade for the cattle, and maybe offset our methane production somewhat. The cattle currently suffer during the summer with zero shade. Solar panels above the feedlot pens would give a duel use to the same area of land without any sacrifice.
Cattle produce more methane because they are fed corn, and do not eat grass, their natural food.
The companies that build these projects want nothing but the best yielding crop ground. It’s the easiest and fastest way for them to build them. They get the added benefit of putting more panels in one place so the power stays utility owned.
@@kitemanmusic That is true, the cattle that would be potentially shaded by solar panels are still going to be fed a diet of corn though and fart out lots of methane, so they might as well have a little bit better life, at least in the summertime.
SoCal is a perfect location. This year for the first time I'm getting electricity credits while running AC whole day long. Thanks to solar panels installed last fall. The fact that LA didn't experience any power outages this year while temperatures hit all time records is a proof of solar panels benefit to the community in general. I will be super excited to see the synergy examples between agriculture and renewable energy production
Well this is my PhD thesis at Purdue University! Thanks for bringing the awareness

Can I read it?
I've thought about keeping chickens under panels for years. Panels would need to be taller(?), and the wires etc safe and hardened, but the chickens would have a roof on their run!!
New technology for electric power generationua-cam.com/video/xc2V2BS_Fng/v-deo.html
I think the chicken tractors could be used with the solar panels roof. Land is regenerative sequstering carbon.
Cattle and other livestock need shade structures, again some Mobile, some permanent. Also regenerative.
If we can sequester carbon through this and it provides power win win.
But it has to be well designed.
I see no reason why some wind turbines be used in conjunction with this to improve grid reliability and lower costs. Either or is not a winner
Chickens driving tractors is a great idea. Gives the human tractor drivers more time to take care of their chickens.
This sort of farming would be greatly beneficial here in Australia where water can be a little scarce at times. Storms come through (hail) and wipe out large area's of fruit.. Grapes, pumpkin, corn, etc etc. Having this type of set up would help protect the plants whilst having other benefits. Water reduction, power production etc.. Fantastic idea.
Indeed 🙏
Every town, county state and council in the world should see this video- agivoltaics are game changers
I love the model of sheep grazing combined with solar panels; I think it could work extremely well with the rotational grazing model: a strip or block of panels will define the boundaries of each paddock in the rotation. It would be important to seed the right kind of forage on the soil under and between the panels, with plenty of legumes like trefoil in the mix. The panels themselves would provide much-needed shade. Ideally, the would supply power to electric perimeter fencing, to keep predators out.
The only problem i see with goats and sheep is that they love to climb and jump. One hop onto a solar panel and bam, destroyed.
@@MsPoliteRants sheep are fine, goats would definitely ruin the panels!
@@MsPoliteRants Panels are hardier than you might think. Goats might be a problem but sheep are not THAT destructive.
Some things just make sense, and this guy certainly had an eye for spotting them. And he has the talent to create well constructed well researched, informative videos.
Don't forget the talent for puns - Badoomts with Matt Ferrell. 😁
This is absolutely fascinating! I know the focus is on large-scale farming and energy gathering. However, I can't help but wonder if this couldn't be even more beneficial if the scale was minimized to households, city gardens, and the developing world! Better and more efficient land use is always positive and would be fantastic in areas where the urban spread is problematic, there are "food desserts', or extreme impacts on land uses due to infrastructure development and expansion.
100% much more efficient to produce the energy (on the spot where it is needed), like you say minimized to household sizes, gardens etc. Obviously though "farms" aswell would be needed, but in the end of the day. Basically any and every househould should become self sufficient more or less with solar & storage. It should really become mandatory for housing etc to include solar already at design stage for maximum output and clean design integrations.
For an example we can already start making our whole housing walls etc in solar tiles. and that is just 1 single tiny part of the story.
For more than a year I have had this idea of combining a track that circles in time with solar movement (similar to circlular sprinklers of industrial farms) with fish/plant hydroponics below them slightly offset. Still requires lots of maths that I am too time crunched to do, and it wouldn't necessarily "make" extra electricity. But my dream is for them to be single kits that can be air dropped into extreme rural areas.
Where they make enough electricity to maintain all of the fish and plant needs; along with the energy to move the rotating solar panels.
A triple combo solar, vegetation and fish farming operation that doesn't need anything beyond water and maintenance.
Go ahead and take the idea, I won't ever get around to designing or patenting it. I only ask that you actually try and make the airdrop thing a thing, too.
-Your Friendly Neighborhood Druid
No idea wtf youre saying but it sounds awesome 🤠🏏
YES!!! Thank you so much for doing this video. I’m studying Agrivoltaics in my Master’s program right now. I’m looking at geographical political economy under agrivoltaic energy transitions. I’ve found thus far the people-component of permitting agrovoltaics is extremely challenging, but do-able!!
This can absolutely be tapped into. A very good opportunity for both developed and developing countries. In addition to the point of solar production, wouldn't dry and arid regions with a higher rate and concentration of sun solve this issue? I understand that there is more space in between the panel sheets; although using mono-crystalline panels might keep that production at normal levels.
Another regenerative farm/energy synergy would be small scale pumped hydro. A lot of farmers already have solar here in germany and quite a few have irrigation ponds. If it werent for regulations it would be super easy to connect two irrigation ponds at different elevation and store some of the excess energy for nighttime use. If its a big farm with enough land a bigger irrigation pond could supply the neigbours with power as well. Basically paying the farmer for storage could create good effects for village sized micro grids.
One thing rarely mentioned is that not only can plants get light saturated, PVs can convert 10x-20x the received light. If the plants are then saturated by chlorophyll-optimized LED grow lamps, the PV density could be raised to the same as a normal solar farm.
The reduced water usage also reduces the amount of nitrate fertilizer needed, as less gets washed away by irrigation.
In New Zealand, this technology is being used on five solar farms mainly in the country's North Island that are operated by Lodestone Energy. The company lease land from local farmers who still can use the land for farming. It is a 'win win' for the farmer, as they get income from the farm and from the solar farm lease.
Whereitsiamindiannoplesae
A very smart idea!
Another problem I think you missed would be how to connect these farms to the energy grid. It is unfortunately so that you cannot introduce a large amount of energy to a certain area of the grid if no-one will use it, or the grid is not sophisticated enough to handle the amount of electricity. Sadly, the electricity grid out in rural areas are often not well developed and this development introduces a further cost to the agrivoltaic system :(
I don't see that problem in Europe. Population density here is very high here and wind turbines are also popular so there is a way to integrate them into the grid, especially in Germany. In the US I could imagine it being to rural in some places but Texas also somehow found a way to integrate lots of wind turbines.
We should use the right tools for the result we are looking to obtain. In this case study, it was a better crop yield and lower operational cost to the farm on top of generating some energy where it would have generated none before. This model may not fit everything so it doesn't have to be used everywhere. It should be used where it makes sense.
That said, I personally, think it's a great use of space to maximize its productivity.
India is building huge solar plants on arid/waste land, even taken on rent from farmers. Indian States are pushing urban roof top solar plants. Indian Govt is enticing farmers to go in for 50% subsidised Solar water pump which after watering fields the solar juice feeds the grid for additional income. Before holier than though talks, I fixed 9kw and 10kw roof top grid connected solar plants - no bills for last year.
But always wondered about the land usage beneath solar panels. Agrivoltaics is a superb idea but needs more research in the factory and on the farm. Once economic benefits are Visible to Indian farmers it will trigger the next Green Revolution of India.
The solar panels can also be used to collect condensate water or due that collects on them. This will be fresh water in most cases. The reduction to need for water in the arid regions is a far greater advantage. In inhospitable regions fodder crops can be grown in waste containers under the solar panels.
Excellent video, Matt! I run a few subs on Reddit and have been sharing your vids over there. I also teach people how to install small off grid solar and build sustainable and affordable housing.

Damned good video! I've been advocating and thinking about this since 1968! Our So. TX farm was often too dry to grow Maiz or grain. I advocated stringing solar panels on wire rope or steel cable to suspend the panels above the ground and allow the tractors to get to the ground. Less water evaporation and regulated solar exposure would maximize production. Plus eventually there would be electric tractors. But who is going to listen to a 14 yr old!
Well you're not 14 anymore.
@@shahbazfawbush LOL! Thanks for telling me! I'm 67 now and who wants to listen to crazy old men?!?
Solar photovoltaic technology is really starting to play a role in various industries, and I am glad to see this. It is a very environmentally friendly energy source👍
Solar Panels plus corals? The ability to control sunlight intensity on some nearshore coral reefs may be another application of this technology that is a win-win. Researchers, such as Scott Condie, are currently investigating what amount of shading is beneficial for corals that experience thermal stress.
The Undecided video collection is such an excellent video series on current technology!
An alternative and reliable income source for farmers plus the potential for increased crop yields?
What is not to like?
I think this is so important and impressive that it shouldn't matter if you have to make small sacrifices. It's especially easy if the farmer owns the solar panel or has a fixed interest rate. But even for the raspberry farmer who needed a weather shield anyway it is a benefit. I think a lot of time and thought should be put into the building of these but that they are so efficient for land use its actually crazy. Imagine doing this on city rooftop greenhouses on every building sturdy enough for it.
It has started to be used even in chicken houses in large farms in Turkey admin . Hello from izmir 🙂
Great project, I hope that some day most of farms will dual use of land, I have 5 acers of land at my home country (Jordan) and you gave me a great idea, thank you
اظن لو استخدمت الطاقة الشمسية باستخراج الماء من الهواء بيفيدك كمان
i think if use solar energy to extract water from air for plants it also helps in dry area like Jordan
Very interesting video. I am currently working on those projects. I would like to mention that a very crucial element of those systems are the sun trackers. Installing panels with sun trackers on those systems except from increasing the energy yield will lead to a decreasing of the structural cost. This would be resulted from their ability to change angle when needed so in cases of strong winds, they can be set to move horizontally so they will add less stress to the structure. (elevated panels are expected to face stronger winds so an installation with fixed tilts will need stronger supporting structure)
while trackers are great for increasing yield, they are also mechanical parts and those tend to fail. I've studied many cases where the trackers failed 5-10 years out. Solar panels are getting so cheap and better a capturing at various angles - that the necessity for trackers diminishes. You can just have you field divided into sections with different fixed angles and over panel your inverters - easier and more reliable then trackers.
As a technologist, every so often I feel a strong urge to become a farmer. Can't be the only one.
Been investigating Hydroponics and Areoponics with a similar pull in mind, adding Solar panels near the greenhouse for that with some shade loving plants underneath sounds like a great option to get more green goodness for the money spent
The joy you get from your harvest is so inspiring
well-made video about a very important subject. In very sunny countries, there is an increasing trend for covering plantations with nets to reduce exposure to direct sunlight to improve fruits quality. However, PV panels installation poses a risk that is overlooked many times. the panel changes the rainfall micro-distribution and on sensitive soils, it may accelerate soil saturation and soil erosion. Considering the increasing intensity of rain events, it might require re-thinking of the design and risks management.
Very enlightening thank you
This is an awesome idea, especially as we are struggling to transition into electric motors, I think if these agrivoltaics were turned into electric charging stations farmers would be more encouraged to set them up.
Perhaps agrivoltaics could help cultivate desert regions, with the solar energy powering atmospheric water harvesters. (Or ocean floating farms with powered desalination??)
This. Ocean farms need to be explored more. Depending on the produce, it could work with a reverse osmosis system. And besides solar, there's electrokinetics. Harvesting energy from ocean currents would be a bonus.
New technology for electric power generationua-cam.com/video/xc2V2BS_Fng/v-deo.html
They are doing this in China turning the desert green with food.
True china is doing agrivoltaics in Kabuki desert
How in ocean floating farms, insects can go in and pollinate? Unless you are farming genetically modified seeds? Don't try to make fools of the viewers.
I admire the hard work you put into your farm and how you document everything for us to learn
Fascinating. I'm thinking of ground-mount solar for my home. I have a perfectly south-facing hillside in my large backyard. I'd like to expand my bit of terracing and to more gardening on the hillside. Since my electric use is pretty steady throughout the year, it'd be best to optimize the panels for winter production, which means production would be low in the summer, but close to matching winter production, so it's okay... no, that'd be perfect.
Because of winter optimization panels will be steeper than 45°. And of course to set the panels so lower rows don't shade the rows further up the hill, they'd need to be spaced apart. Like that berry farm in the video, I too have hail problems. So perhaps something like hardware cloth between the rows of panels could be a real crop saver. The increased expense will be only getting 2 posts from a 20-foot long steel pipe, rather than 4 (panels mounted high). And the extra cost of hardware cloth vs something cheaper like shade cloth (because I need more sun to pass through).
I have not terraced my hillside yet. I suspect I could optimize placement of the panels so in the summer they spend part of the day shading the stone walls of the terrace and not the crops. It could work. I'll have to do a bit of engineering.
Lovely.
This system of programmable adjustable pvs is proving interesting for high value crops such as vines in top of the market wine areas of France. Given that in SW France we've already gained 1.4°C temperature, I expect to see more of these apvs installed over the next 5 years.

Great idea. But I think it’s probably better to focus on getting non-arable land to produce energy at low cost before we try to do two things at once
It's depand the area where you live in this world
Many areas don't have any non arable land that is available for use.
Will try this in my wife's hometown in Thailand could be a gamechanger for the community.
Yay for my buds at UwMF and JhaT !
I especially hate the idea (not agrovoltaic) when I think of all the surface occupied by industrial buildings with huge roofs and no panels.
Maintenance would be hell.

@@bensear exactly
@dannyblast3392 would it, though? I'd rather be able to get underneath the panels than have them bolted onto a shingled roof, like a residential setting. As long as they're high enough not to conflict with plant growths, I don't see much of an issue.
i just gotta say i love you man, i dig every single one of your videos and its a pleasure to see you grow. Peace
Edited after watching video: and i forgot to say one of things i like is the way your present it: straight to the point, fitting a 45min documentary in a 15min format with the added je ne sait quoi and fun included. thanks, ill have some more of that!
This is so great what you can do with the PV. I work as a climate change person for a community. They want to build a PV plant soon.
After what I have seen I'd highly adovocate this. Maybe local farmers can be motivated to do engage in PV-agriculture.
But in Germany they also want to put PV on bogs. Since they are so rare in our anthropocene I would loathe using bogs for PV.
Thank you for this. I am intrigued. I just might have found my calling. I think agrivoltaics is a great compromise!
I remember that when I was a child most of the emphasize on solar energy was about panels used to heat water with sunlight. Of course, since they were using direct sunlight their efficiency in warming water was higher than obtaining electric energy from sun and turning it into heat again. I was wondering that why don’t we use a combination of both solar panels which make electricity and solar panels which heat water on the home roof? The sunlight can primarily be used to make electricity and since only almost 20 percent of the sunlight energy is turned into electricity, the rest which turns into heat can be used to warm water which passes through tubes beneath the electric solar panels and is in direct touch with them to absorb the heat. By this way the temperature of the electric solar panels will also be reduced by the heat absorbing tubes filled with water and this will always keep the efficiency of the electric solar panels high.
As with all great ideas!... It's already been invented. They are still in development/new, but they work just like you describe. A photovoltaic solar cell on top to produce electricity, with conventional solar tubing directly attached underneath to heat water. Only a portion of the roof would need to be covered by this type of combo solar panel, because you can only use so much hot water.
@@stevehazim5823 Thank you for your information.
this is a pretty amazing option that needs to implemented world-wide and quickly!
i think this is the real solution to solve the food crisis and environmental issues in the same time. It may not be worth from the perspective of the investor but this will give the people more food, more clean energy with less pollution => very sustainable 😊
I love your channel music. I never get tired of hearing it. It’s a masterpiece.

This channel usually provides a bit of hope to me which I appreciate. I really hope things like this can become profitable because things still aren't bad enough for people to simply do things because it's the right thing...
That's one of my biggest concerns in general. Until things can be justified cost-wise, it's hard to get everyone on board. Hopefully costs around this continue to drop.
I can't believe how many times I said "things" in this comment. It was ridiculous LOL
@@UndecidedMF One thing that would be great would be to have a financial analysis of this solution. I’m thinking a spreadsheet breakdown so we know where the math doesn’t work. Financially, if look at farming it has irregular crop yields year over year. I see similar for PV energy production. However, I wonder if on average over a 20 year period the PV’s would be paid for (past BE point) and producing “free” electricity / profits from PV array. Similarly, I’m curious what percentage of the time the crop yields would be lower than traditional farming. I have to imagine having structure over the crops would make the yield slightly more predictable and consistent as its protecting from some of the harsh elements. Lastly, if we combine smoothing out the volatility and PV profitability in later years what would it mean to the farmer’s ability to get better long term interest rates for capital required to run the farm (i.e. it becomes a potentially better investment for the banker). Thoughts?
I wonder if they have rain water harvesting on these arrays of panels, would seem like another efficiency boost?
Hi Greg, wonderful point. We have implemented rain water harvesting along with vegetable production in green house integrated with semi-transparent PV panels with different packing factors and the results are promising. check out this video for now, we will soon come out with final video.
They do have some hydro panels out for commercial sale currently that you can find but I’m not sure they have been efficiently paired with farming yet?
I have seen it done before, the water was harvested and used to support a fish pond.
The fish pond produced ammonia from waste then bacteria cycles the ammonia into nitrate and phosphate which is used as nutrients for the farm. (They also sold the fish which I believe to be tilapia….although I have absolutely no doubt that trout would be a better substitute for our markets and just as good at the above)
That would work only in green house or semi-greenhouse with drip irrigation. Horizontal panels decreasing evaporation from soil that is unrelated to plants may be enough
Yes, we have and not only.
Matt, what I love about all your videos, especially ones that discuss the contentious space, it's your willingness to put forward the pro and con argument, all in the same segment.
The contest of ideas and the debate in the discussion, is the only thing that will move us forward as a civilisation and society.
Thank you for the videos mate 👍
