Very interesting! Thank you for conducting these experiments! Always a thumbs up and looking forward to more experiments with solar.
You're welcome! Glad you enjoy the videos. Thank you very much for watching, and thanks for all the great videos you produce!
Project farm I'm a big fan!, Second reply to your comment 😊
Hey whats ur opinion for making a 10kwh project using 100 mirrors on 100w solar panel, with liquid cooling, will it withstand 100times of electricity flow through its wires and reliability and all, pls enlighten me.
I need efficient and economical
@@electronicsNmoreSir, why don't you use flowing or stagnant water or a CPU cooling fan beneath the heat sink I hope that improvement could decrease the temperature by at least 20 - 25°C more.
Anyways you did a great job by at least trying to conduct this experiment as I was longing for this since childhood.
Thank you so much
I hope you conduct future similar improvement experiments.
Great! That's about as much as anyone is going to squeeze out of that mini solar panel w/out an active cooling syst3m. I really appreciate your frequent monitoring. I'm always interested in how things are changing, and it's frustrating when ppl making videos don't monitor those changes frequently. So, thanks!
Larger heat sink submerged in water, please. The panel itself should stay dry.
If enough viewers request it, I'll definitely test using water. Thanks for watching!
@@electronicsNmore mineral oil coat the back or parts needed they run hole computers in the stuff
Константин Дьяченко most solar panels are water resistant
water? the only way is that the container with the water needs to be aluminun too, other way ....it is like, two differents metals plus electrolite (water) and corrosion will start.
@@brandonjohnson6645
I was thinking something similar...
I built a 3 phase rectifying diode array that is rated for 600 amps/6000 volts and placed it inside of a sealed half gallon container full of mineral oil.
Due to the super efficient cooling, I'm able to exceed the theoretical ratings to the extent that I can't get test equipment that will read that high.
The voltage tested has been so high that the mineral oil has been used to suppress arcing between the leads...
So immerse the aluminum heat sink in mineral oil in this solar panel experiment, then repeat it using a peltier device rated for about 5 volts in the same rig.
The end goal is to see which is a more efficient method of passive energy generation.
This could spawn a whole series of videos for an enterprising mind.
Man that’s super interesting I really like this idea I wonder how it scales up
Glad you enjoyed the video! Be sure to rate thumbs up and share. Thank you
I have put some thought into it. I suspect that the biggest hurdles in scaling up would be optimization of lens orientation, light diffusion, and the implementation of adequate cooling. As you scale the size of the solar cell, the lens size and orientation changes. As the lens size increases, the need for cooling increases proportionally. The size and complexity of the cooling system also depends on the size of the panel and whether or not it is stationary or Sun tracking.
Basically the platform has potential, but lacks easy implementation options. Large scale manufacturing would help to lower the difficulty of installation, but the cost would be prohibitive. Making modular systems with commercially-available parts could work, but then there is added cost in labor and materials beyond what a solar installation already requires. There is a tradeoff somewhere and then you get hit with the law of diminishing returns. For every extra dollar, resource, or unit of time/energy you put in, the extra returns are smaller than previous increases. This makes the system unlikely to be popular; at least until some brilliant chap sorts out a commercially-viable solution which bypasses a majority of the complexity and/or cost.
TL;DR: Scaling this up would be a labor of love. Commercial implementations are possible, but not likely to be very practical. The cost and complexity outweigh the added benefit. Custom solutions will be difficult. God speed if you wish to try.
Fun experiment!! Awesome 😁
Thanks for watching Will! Keep up the great videos!
Interesting video. I'd love to see a water cooled solar panel.
I may try that. Thanks for watching! Be sure to share.
I seen that done so that the panel floats so that the panel is in contact with water
I always wondered if there would be an increase in power using a fresnel lens. Thanks for doing the tests 🙂
You're welcome!
I live in Saskatchewan, Canada.
It gets STUPID cold here in the winter, but there's a LOT of sun.
Fresnel lenses during the winter might be a good idea to boost solar panel output, and the increased temperature wouldn't be a huge problem (as long as the lenses got removed before summer).
I agree, using in the winter is the best use for this idea. Thanks for watching! Be sure to share.
Or just buy more panels or larger output panel.. easier and more cost effective
@yeah I'm John Assal Fresnel lenses maybe cheaper than solar panels but the sun moves and therefore so does the focus, so the panels would need to be mounted in a frame and track the sun, and that is definitely not cheap - especially as you would need one for each panel or pair of panels.
I'm afraid that more panels is the appropriate solution to get more power, and/or watercooling them.
@yeah I'm John Assal The subject was Fresnel lenses, they are flat by definition and only work well when rays are near perpendicular.
A parabolic trough partially solves astigmatism in the azimuth axis, but as the incident angle gets further off-axis, the focus moves away from the target. Also, it would still need to track elevation, and the panels would be facing 180° from the sun.
This is not so bad for oil filled pipes, but not for solar panels which need area and need to dump heat. Their capacity to generate also becomes saturated.
All these ideas have been discussed and researched for over 50 years - if there was an easier, cheaper and more efficient way of doing things, then it would already have been done.
Result - adding tracking is still more expensive than adding more panels especially when factoring in maintenance, and they offer no advantage in overcast skies because the light is diffuse and cannot be focused anyway!
@yeah I'm John Assal There is a reason big companies and solar farms don't do this. It isn't practical for an array. I appreciate and applaud the experiment but you would also have to figure size/space and time engineering and aligning cost and it would have to be constantly adjusted for time of day and year as the angles change. Not cheaper by a long shot.
I always wondered when some one would try this. Nice work bringing g this to life
Thanks for watching Vance! Be sure to watch my "Solar" video playlist and share.
Aye I’ve been pondering on doing this experiment my self so please don’t ever allow what people “ may say” to be the determination of which videos you deem worthy or valid to proceed with because this video is so much needed in a time where outages and catastrophic conditions may ensue or we may be victim of currently or in the future. Same methods can be applied if we were only aware of HOW
You're going to need a beam scatter, since the fresnell lens turns incoming light into a focal distance point, and that alone will coock the media of the cells (unfortunately) but with the propper fd and a diffuser employed, you might be able to concentrate the intense light into the shape of the pannel without it (the light) heating up the media, water won't cool the panel fast enough, but that's probably why solar city's tiles aren't that thick, because there's little to do to get more with an "appeal" aspect to solar panels on your roof. If you can work out the fd and the scatter pattern to less that 2" high, you got a good pannel idea for off the grid use. Awesome video! Love your enthusiasm 😊
The focal point I created isn't concentrated, it's spread out over a 3 1/2" - 4" area, so it's not too hot. Thanks for watching!
@@electronicsNmoreUse frosted sheet on the glass too scatter the light evenly and or consider finding a way too slightly rock or move the lens so light doesn't get a chance too create a hot spot
@@electronicsNmore Use a mylar box around pannel so no light can escape and if over hearing store 20 coke cans chop em make a heat sink attach it and if really needed add a 5v PC fan across your homemade sink
am a big fan of your stuff 👍
keep churning out more
A fan from India 🇮🇳
Great video, I believe you are on the right track and did a fabulous job at providing us with those fluctuating numbers "Data" it's very helpful - maybe in the future we can improve them much more with these concepts. Great job again man keep it up. 👍💪

Add a filter to block unnecessary wavelengths, so the panel wouldn't heat up quickly
Cuts power output too much. Thanks for watching!
Great experiment! Fresnel lens was a good idea.
Awesome... once I realized the thermal issues with solar cells and capabilities for optimizing performance... I've wanted to perform an experiment like this. Seems water heating can be incorporated into solar cells more maybe as well as maybe incorporating with convection solar heater systems. Thanks for sharing!
You can use mineral oil. Its non conductive and cools
@@rb-ro2po Good call. Seems like for a heater or geothermal application... a closed loop system would be better maybe factoring in the coefficients of thermal conductivity or something like that. For only cooling the solar cells... seems can pump the heat into the ground... maybe depending on the environment... under a greenhouse, home, shed or garden I guess.
@@jafinch78 that and you could treat the solar cells like how you would try to cool a computer and use a pump to circulate the mineral oil for even heat distribution
@@rb-ro2po Great call! Sure... why not just use the water/fluid CPU cooling computer parts maybe even. Heat pipes would be a bonus also.
@@jafinch78 Heat pipes aren't used in water-blocks, but simply slapping a heatsink tower on the back of the solar cell with non-conductive thermal paste aught to be enough for practically any normal use case. wouldn't even need a fan if it's breezy out.
As for liquid cooling: They even make generic 'stick on' water blocks that would work fine for this. For scavenging some extra work out of the fluid, you could use low-temp Sterling engines, but as they have so little torque, getting voltage out of them isn't too easy. You might be able to replace the flywheel in such a setup with a fan to get some air moving over the heat sink for 'free', but the pump is going to need power from the cells to run. As for how big a radiator would be required? with a .2 amp 12v fan and 120mm rad, it should be able to dissipate 80w-100w of heat from some off the cuff guesswork on my part. As concentrated photovoltaic systems benefit *greatly* from higher-quality cells, you'd want to use them to maximize the 'net' gain from the system.
using liquid cooling allows you to use mirrors as well as lenses to get some pretty mind-boggling output out of the most expensive cells. At a certain point they'll just burn though.
I worked for Mobil Tyco Solar Energy, formally Tyco Labs, in the 80s. We manufactured and sold systems just like this, Fresnal lens concentrators with water cooling. The difference was our systems were linear as opposed to square like yours. We manufacture the solar cells as well using the EFG thin film growth method. Electricity and hot water from the same system. Then oil prices crashed and it was very cheap again so Mobil sold the Tyco Labs and moved on. I think the company is still around and building flat panel arrays.
Great info! Thanks for watching
I would love to see this go into full development again
Should further collect the thermal energy via a peltier chip to the heat sink.
Then you'd need to cool the opposite side of the module.
@@electronicsNmore I think Todd is saying you should put peltier junctions between the solar panel and heatsink to collect more energy.
@@0JThomps0 And drive a fan with the collected power to cool the heatsink.
@@resetcoder it would probably barely be enough power to turn the fan slowly. Peltiers are pathetically low efficiency.
@@jkenny1 i know that is why i said that, to make it completely pointless, but at least more difficult
Hey Doug, If I remember correctly, pardon if I'm wrong. Where I may not always comment, I have been a loyal sub for many years and watch every video in its entirety. A very fine channel with great diy tips and tricks. You should be a UA-cam top money maker. Thank you for all the time and effort, not to mention money to produce your videos. I'm watching in Willamina, Oregon, also known as Timber Town USA. It's on the way to Lincoln City on the Coast, but, I'm just on the inland side of the Coast Range, 25 miles to the Coast. One of my oldest subscriptions. All the best, C.
I remember your YT channel name, thanks for being a long time subscriber!
Hi Doug. Loved the experiment. Has always I Liked,Shared. All my best.
Thanks Bobby!
The argument of this setup is lens + cooling + small solar panel -> cheaper than a large solar panel.
Nice videos, good testing, the most important problem all world have is to have efficient battery technology,
Glad you enjoy them! Please share. Thank you
The fresnel lense is about 8x the area of the solar panel. Since the power developed with lense is 4x the panel alone, the system efficiency is about 50%. 8 solar panels in the same area of the fresnel lense would develop 2x the power at a lower temp at the panel
As I said in the video, it was only an experiment, one that many people requested. Thanks for watching!
But solar panels are current devices? They have a maximum power point if you limit the current draw
I believe that solar panels get their energy from the ultra violet part of the light spectrum if your lens is made from plastic then you might get a better result with less magnification via a glass lens as I’m fairly sure that most plastics block out a lot more ultra violet light than glass. It’s a worth while experiment as it may prove practical in extremely cold climates when power lines are down or when there is a lack of sun light.
Thanks for watching Tim!
Interesting. Cooling might also help with the longevity of the panel as well.
I thought about doing something like this with a large panel, and adding water cooling, I was just curious if it would be effiecent enough to be worth it, with the loss of the pump and added heat, maybe with a 350 watt panel it would, but wouldn't last as long. It would be good for short term camping or emergency power, plus you would get hot water! Great video!!
If you have to take power for a motor, no good. Thanks for watching!
Maybe a slow convection-based water flow, with the downward flow in the shade.
Would that take away enough heat, though?
Thermal siphon feeding cool water from bottom of tank and warm water rising by itself into the top of the container. Look at PC water cooling systems. Electric pump is unnecessary. Add fins to water container to dissipate additional heat.
Whether or not forced cooling would work depends on whether the additional load is smaller than the gain from increased efficiency. If not or it comes break-even, then no. But if it's significant then the answer would be to go for it.
Would be very useful on a larger (house) scale. You could use water for cooling, then use the heated water for something else eg filling a hot water tank / central heating system.
I would say no. While you could theoretically increase the output, the loss in lifespan is so high, that it wouldn't be worth it. You are probably talking months, not years (lifespan.) Even with active cooling, the surface of the panel is going to be ridiculously high.
There is also a lot of danger in Fresnel lenses. Wind could cause the Fresnel lens to move and concentrate its beam on the roof and set i t on fire. I have an 8.5x11 inch Fresnel lens I can set green wood on fire instantly with it.
@@tarstarkusz The light isn't concentrated to a tiny point, it's spread out, so the heat will be nothing like a TKOR "solar scorcher". Thanks for watching!
@@electronicsNmore I wonder if you could avoid some of the heat by using a mirror instead of a Fresnel lens? I realize that it's not concentrating that much, but that's the problem with the Fresnel lens. If you accidentally move the lens in the right way, it creates a death beam.
There are cogeneration panels, but if you want hot water you're going to run the cells too hot. Perhaps heating a lap pool would work.
Knowledge is wisdom👍
Think about it this way, experimenting with a small panel is the way to go because the same logic should apply to a large panel, but the costs are lower if you destroy the panel and also lower costs to get the heat sink to cool the panel.
Great video! Loved it and am now a subscriber! 😎
I think this experiment shows the promise of CSP.
Thanks for watching Ben!
I also thought using convex lens and Fresnel Lens to increase solar panel. However it is a hassle to set up them in the correct position. It is better just to buy more solar panel. The new solar panel product is half cell solar panel.
Excellent video and brilliant thinking. Thank you!
Awesome test project. Great way to test a hypothesis. Thanks
Glad you enjoyed the video! Please share. Thanks
FYI Be sure to wear eye protection. A fresnel lens can focus the light bright enough to damage your eyes. My 4' x 8' panel is hot enough to burn wood.
Like on your videos sir you. Keep on making these videos
Glad you enjoy them, if the views increase, there will be many more.
What about putting the F lens directly on the solar panel(s) and seeing how far away from 90º you can get from the sun, before losing output? Use those concentric rings to gather light from different angles and point it down onto the PV cells, ya know?
What if you put a mirror under the solar panel, flip the panel upside down then focus the sun again through the Fresnel lense. Since heat rises maybe it could rise easier into the heat sink. Maybe also the light coming through the mirror could have less infrared heat?
Heat does NOT rise.
Less dense materials rise.
Most materials show decreasing density as temperature increases.
That isnt the heat rising. Its the material.
Heat simply flows to achieve equilibrium. No direction.
Exact same thing, but add a container of water under the bottomside of the heat sync? Can we get it cooler with "off grid" means?
Cool vid
Instead of a heat sink, try attach a peltier module (TEG) to induce cooling of the panel
They waste too much power.
Ant on the frame at 9:33........"Uh NOPE!"
😂
@@electronicsNmore Anaaaaand at 9:43 he makes a quick dash at the back of the frame right by the fresnel lens into the corner too!!
"Holy CRAP it's HOT right here!!"
Can several the fresnel lens enough to boil water to get distilled water under sunlight in fine weather for a whole day?
Too much work tracking the sun.
So glad you did this... :)
Glad you enjoyed the video! Be sure to watch my other solar videos below, and share links to my videos on social networking sites. Thanks!
ua-cam.com/video/B16hHEaWwpI/v-deo.html
The heat sink will saturate under bright sunlight, definitely needs active cooling.
The test was bright sunlight, and the heat sink I added was a big improvement.
If you are going to cool the panel...
What if the photovoltaic panel is the surface of a thermal solar collector. That way you get electricity and a second harvest of hot air or water.
That's beyond the american mind, Alex...
interesting test. the heat sink would work better if you flipped the panel & heatsink so thr sink was pointing up & used a mirror underneath to aim light from the f, lens at it.
This problem very famous among "DIY LCD Projector" people, LCD matrix from usual LCD monitor, when black screen picture is there, receives all energy of lamp optical system. best solution - layer of water, 1cm is not best idea, but after 30mm of H2O Light will be wery cool
Very good. Thank you.
You're welcome! Glad you enjoyed the video. Be sure to share.
If we use LED panel and magnigying glass may work well
tbanks for the great video, will post to social media
Glad you enjoyed it! Thanks for sharing.
Aluminium square tubes that are 8mm OD 6mm ID or 1mm wall using surgical rubber tubing to join ends so that the flow of water can go from top to bottom with a small circulation pump would cool a larger 200w panel with a Fresnel Lens. From a 200w panel you would normally get about 60% power or 120w without using anything else to get higher efficiency. If you use a Fresnel Lens & water cooling then perhaps you could get about 90% of 200w or 180w less 10w of power for the pump giving 170w which is still 85% of it's rated power.
I wonder if you could submers your heat sink fins,only, in a container of water. This I imagine would disperse the heat much faster. or and absorbent heat gell of sorts. Nice vid. Keep it up. Subbed
Would using a sphere full of water decrease the temperature without the use of a fan while producing a high power output?
That would still generate heat. Thanks for watching!
Great video. I liked and shared.
Thank you!
Would something like this be worth doing to a bigger solar panel to increase power gained?
Awesome experiment! I wonder what the numbers would be on slightly overcast days or in cooler weather.
A bright sunny day with cool/cold temps would keep the output voltage even higher. Thanks for watching!
I just shared and subscribed. I really like your concept of using the lens. Can you please scale it up to a 50w panel or more. This would be great to demonstrate the practical use of adding the lens.
Thank you! I need to look for a big screen TV. :-)
electronicsNmore check online for a larger lens or what if you experiment with them tiled together?
Saw a similar experiment years ago, the issue was addressed by submerging the panel into shallow water
Yes, that's next, but you need to circulate the water, or it will get very hot quickly. Thanks for watching!
Would adding a small fan to the heatsink draw more current than what could be gained by keeping the panel closer to ambient?
You'd be losing. Thanks for watching!
A heat pipe attached to a thermoelectric generator to power a small fan to dissipate the heat might lower the temperature even further.
I'm also sure that with enough people looking into your Fresnel lens solar they could find cheap and good parts to continue this.
Hi Frank. The problem is, the Peltier module needs to be cooled on the opposite side for it to produce a lasting supply of power. Thanks for watching!
Hi, I’m wondering if some sort of heat exchanger could be used to kill two birds with one stone. Cool the solar panel and charge a thermal battery?
Thank you for your effort
It would be nice with added graphs and tables.
I'll take that into consideration for future videos. Thanks for watching!
Thank You !
You're welcome!
Ain't fixing shit.
I know this is older but couldn't you use a fractal lens just to redirect light onto the panel with out magnifying it? I know eye doctors use them to redirect light into the eye for some patients with weak eyes. Maybe it would help with solar panels
Curious if photovoltaic is better than Sterling engine with lens
shows passive cooling works, just need to move on to active cooling, Fan and maybe some form of liquid cooling.
Liquid should do very well. Thanks for watching! Be sure to check out my wide range of videos, and share the links.
There are actually solarpanel projects in oceans and lakes for cooling. So it is not an irrelevant idea at all
If you put peltier module under the solar panel and then a heat sink... Can you generate with this system even more electricity and provide cooling for the solar panel as well?
try in a vacuum!! u could also make a cryo cooler! need 2 be familiar with cryo!! super simple though...
Great suggestion. I have a vacuum chamber.
@@electronicsNmore .their was an engineer, that made a ''reinforced' vacuum box. 4 ''proof of concept''...but, I don't remember. if it was a ''zero vacuum''. or a ''pressurized vacuum'' +ATM or - ATM??? & the box was over/on top of, the solar panel..but seriously! it stopped ''all'' negative effects from the sun!!!
they also make a high-temp epoxy, that is ''perfect'' 4 hot applications!! U can take a butane torch 2 it!!! no UV coatings, just pure photons!! also, if U knew a little about ''optics'' U can produce an ''un-focused'' optical telescope. that will have the ''intensity''. but little heat? that's the ''key''!!
''NO HEAT''..good luck with it !! if I was ''able'', and had the time! I'd give U some more hard luck stories!!
Magnifiers and high lumens leds to charge at night would be a good experiment.
Thats how you can fuse Photovoltaik and Thermal Energy. Why the Industry issnt using fresnelllenses on the big panels with cooling? I am sure its possible to push the temperatures even highter with special panels without loosing voltage and getting steam power :D
Thanks for watching! Be sure to share.
The fins would cool substantially better if they run vertically instead of horizontally.
True, but it wasn't easy finding that particular heat sink.
@@electronicsNmore possibly you could cut the heat sink in half with a hacksaw, and turn the halves 90 degrees?
I've been really curious about this exact experiment, so I want to see it run with optimal execution to see if it can be effective enough to be worth it in a larger scale application.
Next level after this would be heatpipe to a radiator in a water bath. Keep up the great content!
GOOD WORK 💙👍
"you can not work for free" hahaha, you are funny
You work for free? I don't find it funny at all. The problem is, we live in a society where people are always looking for
"hands outs", they think they're entitled to everything, and do nothing for others in return. My entire life I've helped others.
@@electronicsNmore what I thought is funny is that youtube is a platform where most of the people who create content receive no compensation for their work, youtube is basically a slave driver corporation, and you complain that you aren't getting payed in your video, also guilt tripping us isn't going to do anything, people know when they are being manipulated, and for me at least it's going to drive me away.
It might work better if you put it in a A.C cooled box
Did this ever get re-tried with water cooling?
Your approach is backwards. Cooling is helpful but requires NRG which causes pericitic loss. Set the lens away casting only the needed amount of additional light to find a sweet spot for maintaining cooling while producing maximum output.
70°C is pretty hot. Using a CPU heat pipe or a water block would keep temperatures lower.
I can get it lower by making a few changes.
I also believe the heat sink is good without lens. With lens you can add bigger heat sink or water cooling.
Yes, it would help keep the panel output voltage higher. Thanks for watching!
What about spreading the focus of the len with smaller ones so you can reach more of the solar cell?
A fan on the coil solar driven might cool more like a computer cpu
I'm wondering if it could be better with some extra passive-cooling. If you covered the fins of the heat sink on the side farthest from the panel, and add some ductwork to the other two ends. One side going straight down, staying in the shadow. The other one going straight up, or at a slight angle to clear the edge of the fresnel lense, to encourage a strong draft. It's such low temperature that you could get away with prototyping in cardboard as it can take up to about 500 degrees. Looking at the profile of the heat sink, it looks like the cardboard box from Macaroni & cheese might work well. I would think that at least a foot of rise is needed for a decent draft. Two would be better.
I think a water cooler heat sink is best.
@@electronicsNmore Agreed! But you have to move that water, and that lowers your output. It would be worth it if you get more power out than needed to run the pump. Testing is required. Passive cooling is easy and will definitely provide more power.
That is not cooling. It's just prolonging the inevitable. You could make an active air cooling for constant readings. Or water spray cooling, as some other enthusiasts do.
Very awesome video as always, thanks for the experiment!
You're welcome, and thanks for watching!
You should try a panel the same size of the lens vs the lens and the small panel. My guess is the big panel makes more power
That defeats the purpose of the experiment.
I wonder how a TEG chip would do instead of PV.
Are you sure that thing you have plugged in there isn't a remote control for a bulldozer? Everytime you press the buttons I can hear the reversing alarm from plant equipment. I would check over the fence next door, make sure your neighbour still has a house......
🤣 I filmed the video is a "quiet" area, except for a gate the beeps when opening up.
@@electronicsNmore Ahhh ;) Thanks for the reply, interesting stuff.
If you had a huge panel and did something similar, could you generate enough power to run a water cooling device to cool the panel? Sort of sounds like perpetual energy kind of situation.
You always lose, never gain. :-)
Definitely try better cooling. Liquid, perhaps even oil. Peltier would be great, but probably too impractical to set up a test.
If enough people want to see more tests, I'll do them. Thanks for watching!
What if you submerged it in a thin film of water. Could act as a anti dust solution as well to keep it clean for a long time.
Dust really isn't a problem, the heat is, so using water to cool the heat sink would work. Thanks for watching!
awesome video!

ua-cam.com/video/B16hHEaWwpI/v-deo.html
could you try placing the heat sink in liquid nitrogen
Interesting idea. :-)
Hi could you please guide me buying a Fresnel lense so as to produce a solar concentrator.
I am currently dealing with the application of nanofluids for optical filtering so as to increase the efficiency of solar cell.
Do you have a similar video with a spherical lense?
No, maybe in the future. :-)
I recon that water flowing over the panel would cool it down enough to allow for the wattage use of the said motor.
You wouldn't gain anything by adding a motor.
electronicsNmore that would depend power the motor consumed a extra power you got from cooling the solar panel
Try the panel with a water cooling system
I don't understand how the Fresnel lense helps increase the voltage output of the cell. Isn't the PV effect based on frequency and not intensity?
Higher light intensity = higher voltage output to a degree, and higher current output. Thanks for watching!
@@electronicsNmore hmmm, I must be confusing something. The photoelectric effect shows that light intensity doesn't matter, it is the frequency of the light that dislodges electrons.
en.wikipedia.org/wiki/Photoelectric_effect
What about a solar panel the size of the fresnel lens?
Won't work
