I installed a 5kW solar array on my house's roof 7 years ago and haven't paid for power since, and it charges my EV, so I don't pay for gasoline either. Yeah, solar can definitely solve the energy crisis.
What about battery? You should be changing one in 8yrs.
No, solar is for rich kids in warm countries. In many parts of the world the output from solar is minuscule during the time we would have the greatest need of energy; during long cold winter nights.
@@SweBeach2023 solar is for developing countries actually. It's the developing countries who occupy most lands where solar will work the best.
It could solve your energy crises. Lets be honest. I love my solar system, but my 2kw system at 72degress north(72% efficient) I only collect about 6kwh a day, out of the 38kwh a day I use....Not counting my vehicle, or heat.
I am completely off the grid with a 6.5 kwh solar array and 25 kwh lithium battery bank. I power 3 split A/C units and all other appliances.
Solar is definitely worth it and it can help to save the planet
I live off grid on a boat .
I use 39kg of gas per year, and solar fulfills all my electricity requirements a year, plus my propulsion is electric !!
Solar and wind turbine is the answer !
If you can't afford to fill your roof with solar , think out the box and convert 80% of your electric consumption to 24 volt !
A full off grid set up can cost you as little £ 1200 ...
The problem is that you need a fairly sizeable turbine to generate enough power for a house with 4 people.
@@PaulMansfield a friend of mine got his neighbours together and they all pitched in for a turbine ... all 80 of them ! The planning permission was granted and the huge turbine erected on wasteland near their estate ( ex council houses ) . It cost them £23, 000 20 years ago . ( 285 each ) . Their yearly bills have never exceeded £ 100 .
Now I'm sure turbines have improved in the last 20 years and I know for sure they are cheaper !!
That turbine still generates power for at least 80 households today !!
Name checks out
@5:00 The maths are wrong. It costs 3500 pounds and produces 1000 kWh/year. If energy prices are 26p/kWh, it would pay for itself in 13.5 years (3500 / (0.26 * 1000)). If energy prices go up, it pays for itself in less time, and vice versa. The 20 year warranty has nothing to do with the payoff time.
That's assuming you can use all the energy it generates. If you assume half gets exported, you make only 7.5p/kWh.
Solar alone won't cut it. All sustainable energy options must be used.
Solar alone will cut it , the problem is storage but that's all changing !
You're incorrect
Long overdue. More conversations like these!
Is it just me or other people are curious that it's been 3 weeks that no new episode/episodes have been released yet or has click been cancelled?
That is not futuistic it is ugly and obtrusive. There much better ways to use Perovskite
Brilliant episode, as always! In the article on climate impact, it was stated that an example of a product that has little or no value is an electric pepper grinder. At first glance, this might seem reasonable. However, to someone suffering with arthritis (me!), using a manual pepper grinder is often painful and sometimes impossible. Therefore I own an electric pepper grinder and I place a high value on it!
The article on solar was really excellent. Let's hope that the efficiency of this technology can improve as has been the case with standard solar panels.
Please do update the weekly news please 🥺
Please upload new episodes!
Thank you for sharing.
So, LJ is a Trekkie 🖖 😉. Good to see you so healthy, LJ !
Can anyone tell me the name of the exhibition shown at 8 mins 19s of this video please?
Solar is not the total solution; a mix of solar, wind, hydro, nuclear, gas and storage is the answer for now. As more and more renewables and storage come online so we can reduce gas peakers and nuclear fission. You can't overnight replace any one entrenched technology with new tech.
If we ever get nuclear fusion right that will make everything else obsolete; but once again that will need phasing in.
Been discussed for decades
This system is quite expensive, I don't think it'll pay for itself, even if electricity was 50p/kWh
Shades of solar freaking roadways....
NO as a whole. For individuals sure. Not enough batteries or material to make the batteries to hold the power in reserve for every one.
I'm asking if there is a software that a help of eye glass and hearing aids can see and listen sound of Jesus ( Angel's) and Devil's ( Damon's , Evil's ) or a video camera software that both appeared ? I have no credit USA card can you a help me ask or apply Microsoft HoloLens or other software company?

I don't know about you but I close my blinds at NIGHT not during the day. So I'm not sure having flexible solar cells on those blinds will be that useful.
Maybe in warm climate in a hot day they can be used to block solar gains if they are outside of the inner glass panes. at winter time that would be plain foolish. if a window is mostly covered, it should be a wall. anyway (in the video) the argument of "i just don't like them" about conventional panels does not help to sell a lot less effective product
Houses tend to be empty during the day, would make sense to have these blinds operating during those times.
The example given was for Spain where you do shut blinds during the day to keep the heat out of the house and open them at night to let in the cooler air.
do simple copper copper-oxide transparent-metal solar cells, on sheets, copper-2-oxide CuO is the most optimal single junction solar semiconductor, yes, metal-semiconductor junction, not doped semiconductor p-i-n, but m-i-m junctions, easiest to make also
if you use heat cooler circulated salt water as the top electrode, you have both water heat collection and direct electric conversion, 2-in-1 package
combined heat pump with solar electric
copper roof
why only 10%, you had 25% as a standard, what made you lose your efficiency, a lie
if you use aluminium (metal) directly as power source and storage, your price is around 45p/kWh
Solar is the worst of all renewable generation types, including tide and wave, which are not particularly good.
It is useful for off grid applications but not as a source of grid supply. Apart from it's poor availability factor it is technically unsuited for a couple of reasons. It cannot load follow, quite the reverse, no inertia, characteristics required for feeding a grid and keeping it stable.
ummm, no, solar cannot solve the energy crisis (all by itself). Solar, and other renewable energy producing methods are only a step in the process, a cog in the wheel of the energy game. But not only does the source of the energy how to evolve, but also how we as the consumer consume the energy and the products we use/request/demand that are made with the same energy. Bring on hyper-efficiency, add lightness...do more, a lot more with less.
No sound
Sound is good here Umar. Try on browser or other device.
No, Solar can not take over from the grid yet. The combination may be suitable for now, but until solar is perfected, it will not be all. Batteries are in question for several reasons, and before Solar can take over, these questions need to be addressed.
Sun has to be clear of clouds, panels must be 100% clean or their rating goes down, don't work at night for some weird reason. surface area of panel must be unprecedentedly massive and you have to create Global Warming to dig up they battery to store the energy till its needed.. yay for He.
All bogus info !!
Solar does not have to be clean as I have drawn more energy off dust particles than totally clean panels !
Monochrystaline solar panels work on cloudy days too !!
Yes battery manufacturing creates emissions but 3 batteries every 7 years is nothing compared to the average house ...
I live comfortably all year using just 1.2kw of solar !
@@jasonwoods3711 Solar panel are 30% efficient at Perfect Conditions ie if you have todays versions Are at 25 degrees ! pointed at the sun, in the process they at heating up the air THIS is why the latest have water cooling. CLEAN. If you believe DUST makes them work better, cover them in it.
@@jonscot8393 I have 430 watts of solar that power my living all year round jon and the rest goes to my propulsion !! Dust on my panels has extremely very little effect at diminishing that power I still have plenty of power all year round !!!!!
They are laid flat in the summer and angled in the winter.... it works for me very well thank you !
A friend of mine lives in a house . He has 8 panels on his roof . He hasn't had an electric bill for 10 years and received a cheque from the grid every four months averaging 300 pounds !!
What can I say ... win win win for us two !!!
I think your site and referrals are anti-society.
@ljrich wanna go out on a date ?
Solar can't "solve" the energy needs by itself. But I vacationed in Mexico close to the ocean last December, and was quite surprised that I did not see even one solar panel! I heard a lot of air conditioning units running, the city and our resort was well lit at night, including the walking paths and beach. It was full sun 6 out of the 7 days I was there.
What I simply do not understand is why people do not take advantage of the free daily sun, to charge LED lighting for the night or even warm partially the fresh water needed to wash dishes at the restaurants and hot water tanks, that guests use to take a shower or fill a bathtub.
Do you have solar on your roof?
ANWER YES ! We have a third rate government run by maniacs. The UK needs proper leadership on SOLAR if it does not come from the government then it needs to come from a group of wealthy people and companies. Every INDUSTRIAL, COMMERCIAL and MUNICIPAL building needs to be covered with solar panels. I have no objection to using land but we have thousands of large roof properties that are currently naked of power generation. Plus those properties are closer to where the energy is needed than solar farms out in the countryside. It needs to be coupled with both battery storage and battery load balancing. These building would offer total export or battery regulated surplus power at certain times of the year when there are block holidays. Industry tends to take August and the Christmas/New Year period off while schools have many holidays throughout the year. Sports and cultural venues are often quiet with low level activity for days and thus most of their energy can be shared with the local community.
Should move to BBC Three
quick answer yes but not with out current tek its so limited in what it can draw from the sunlight that half if not more of the landmass would have to be covered in panels.
what we need is a change in society not a big one where we whittle spoons in the forest and go back to the stoneages but in regard to how the world is run eg half of the worlds food production is wasted, thrown away.
ΝΟ
I recently looked at getting Solar, but for the panels and battery back up it was about £7k and will likely take 15 odd years to pay for itself. Otherwise would have done as in theory could charge our car and mostly power our home on solar. But 15 years is a long time to see a return.
Same price as a Conservatory that never gets used
Remember that a battery will not only save buying peak rate electricity in the evening, you can charge it off v cheap electricity overnight and avoid buying peak price electricity before dawn.
Back in May 2019, I reckoned my 6kWh (useable) capacity battery would earn it's purchase price in about 9 years when it was installed, that payback is accelerating with energy price rises.
@@PaulMansfield its been sunny today but really cold so ive had an oil radiator running all day . saved a lot of money
The return on investment starts from the day you use it and stop polluting the atmosphere.
Your lungs, health and the environment that keeps you alive has a value too. It's not just about the $$$.
Better still, stop provoking wars with other countries.
Can anyone tell me what happened or the reason why no new episodes are published in this channel?
i think it can make the West energy independent
Hmm... Good intention about the carbon footprint of clothes. I don't think the great majority will buy according to footprint though, it'll be fit and fashion as always. After we have a climate apocalypse, people will probably start to care enough in a meaningful way then. Sadly.
So glad to see DayRize doing this. I've been wanting someone to do this for a while. You get more of what you measure so companies and consumers seeing the environmental score of products finally incentivises them to reduce the impacts of their creation. Everyone needs to use this and Amazon needs to integrate it so you can see the score for anything you are thinking of buying.
Connor!!!!
Thank you for having us @BBC Click! 👏 🤩 ☀️
Those oddly shaped solar panels are going to have a terrible efficiency and be very pricey per kWh. It's simple geometry.
I agree, it's a very expensive system, seems to be designed primarily to look good.
They'd be better off using the film on the windows of the house.
