That's fantastic, that the efficiency of panels is on the rise. The most relevant things for consumer rooftop use, is cost per watt, and cycle life cost per kWh. The graph with the efficiency of many brands by the year is top notch. Where did you get the data to compile that? Excellent research! thanks for sharing.

Vincent Robinette , roof tiles, like Tesla are producing, would be my preference. Do you know the efficiency ?
gregory hatton (5 months ago)
@Vincent Robinette lowest rates in the country ? Ohio has competition, check these rates out … I'm paying a fixed rate of 4.95 cents per kw regardless of how much use. http://energychoice.ohio.gov/ApplesToApplesComparision.aspx?Category=Electric&TerritoryId=2&RateCode=1

you didn't mention the SunPower cells and panels. They have the inter cell connections on the back of the panels so they run cooler. They produce the most power day in day out, are non toxic and last the longest. Some of the high efficiency get too hot and fail. Your summary of cost, life and efficiency is the key.

Actually solar panels contribute to the heat island effect much like asphalt parking lots and shingled roofs that absorb enormous amounts of solar infrared heat energy. This contributes to the warming of the planet because trees were removed to make room for them. Trees cool the planet and the above warm the planet. Other items that contribute to warming are roads, highways, airports landing strips, and buildings/skyscrapers.
Synergy Files (11 days ago)
Its not like that. Part of the energy falling on Solar panels is converted into electricity, some of it is is converted into heat and some of it is reflected. On normal roof tiles, similar phenomenon happens.
Sudheer Aggarwal (12 days ago)
Could you also include the information of mono or poly crystaline in the six panels listed
Jim Stack (13 days ago)
The sunpower panels are best.all coonection on the back. They last longer andcwork best in the heat compared to all others.

More obvious application where space is limited is on EVs. This appears to be starting to become a serious subject with two cars I have seen with them installed, the Lightyear and Sono Sion. Neither in production yet. Both are claiming around 35km max daily range extension, which is pretty impressive. Not sure what type of panels they are using, but it is surely a great idea for any EV.

The average efficiency is 8-13% Maximum. All the given data's are collected from the respective manufacturer's work sheet which are fake and dubious.

In the lab efficiency data is always better than real world.eg.over heating dust on panels shading etc.solar panels have come a long both in price and efficiency.i agree with your point to a certain extent.

The Australian National University has made a new type of silicon that better uses sunlight and promises to cut the cost of solar technology. The new type of silicon created is called r8-Si. Instead of the atoms being square or cubic like in standard silicon, it's more shaped a bit like a diamond on playing cards, only it's in 3-D. The researchers say their world-first invention could help reduce the costs of renewable electricity below that of existing coal power stations, as well as lead to more efficient solar cells. If that is true then coal power plants will be eliminated in 10 years just due to cost. Global warming will be reversed.

The most useless video ever. A list would be enough.
Any mention of internal string optimization? Although it is an available licenced technology for current panel manufacturers, it makes a large year to year overall power production difference in panels with the same efficiencies.
Holywood07 (3 months ago)
Sounds great at first but these are only marketing numbers and I'm missing the real thing here, which is: how much energy do I get from dawn till dusk from a same sized panel. Some less efficient cells start delivering earlier (no direct sunlight) and thus deliver more energy throughout a full day as compared to cells that need direct sunlight and which even drop in delivery when they get too hot (because of too much direct sun).

This topic is pointless as it ignores heliostats. A broader consideration of solar energy is needed beyond the scope of commercial photovoltaics. Efficient use of energy produced from any source lags so far behind efficient production of energy for our needs and desires.

The question is how long do they last and how quick does their efficiency drop over time?
Synergy Files (3 months ago)
The efficiency drops at a rate of 1% of the output every year. So they last very long. The will keep working even after 30 years but will give reduced output
johnmburt1960 (4 months ago)
One more category needs to be added: photovoltaic cells which can be made with cheap, readily-available materials and don't require rare substances which can only be mined / refined at great expense and great pollution. A solar cell which can be made entirely from, say, silicon, iron, oxygen and carbon, would be highly desirable even if it were only ten percent efficient. Something like that is unlikely, but something which just uses less of the rare and difficult to extract substances would be welcome.
Ian Murray (4 months ago)
My 22 REC 325 panels generated 35 kWh of electricity today (in the UK), I am writing this at night using up some of that free electricity stored in a battery, my electricity bill for today is zero and the grid is paying me for selling my spare electricity to them and paying off the capital cost. And that is why solar panels are the future.

I have a Reliable 1000 watt PSW inverter with Soft Start and it has chronic problems running my Compact Fridge which pulls only 175 watts when starting and runs at 45 watts, the 9 watt Led light on the same circuit frequently goes dim plus the inverter idles not at 0.75 amps but at 1.75 amps. Support was more concerned about my Negative review than wether the inverter worked properly, I told them I stand by my findings and suddenly my review vanished.....never again.

Yes. If they are in a very hot environment than cooling is required. There are various solutions for that. One is use phase change material other is using cooling jacket

I remember when semi practical EV came out in the 80's and the big stink was, "They would be viable for the masses if we only had batteries with 10X the power density." Well. Lithium based batteries came out with that capacity and what did they do? Cut the size of the batteries in the vehicles by half or more while at the same time loading up the parasitic secondary power drains in the vehicle until the lithium powered cars were just as useless as the lead acid ones and the inflation adjusted price for one had been more than doubled or tripled for it as well.
Naman Gupta (5 months ago)
Well, you forgot the most important aspect here. Price! Without that parameter, it's impossible to discern what is consumer grade and what is just restricted to labs and such. In future at least give your audience some idea of the cost per watt that we would have to spend to get these.
Naman Gupta (5 months ago)
@Synergy Files Could you share the link? Also, it's a good practice to put a link in description or in the video itself about the previous video that is related to this. I found this video in the suggested video tab and have no reference about the past right now. Although I can search for it in your videos. But, that's not the recommended way for addressing your audience. I hope you will follow this advice in the future.

@WashingtonWebFoot No I'm not. These are important distinctions to make. There's nothing to amend to my original statement and it was perfectly clear what I was talking about.
WashingtonWebFoot (5 months ago)
@John Garrison Jesus fuck. Are you contentious just for the sake of it? There was no guarantee of energy from nuclear reaction for around 2 million years of man's existence either. Where would we be if we used that as a premise for doing nothing? Besides, which part of "I agree with you" are you having hard time accepting from me?
John Garrison (5 months ago)
@WashingtonWebFoot There's no guarantee of that. Simply because it's one of the most diffuse energy sources that we have and one of the most variable. I didn't say it in my original comment because it's heavily implied. By the video, by the media, by politicians, by environmentalists, etc. It's not a solution to Climate Change.
WashingtonWebFoot (5 months ago)
@John Garrison "as a replacement to coal." Why didn't you say that in your first comment? No shit. However, it should be amended to "at this time". Solar is still the most abundant energy source for about 3,000 light years in any direction (that's the closest Black hole). We just need to crack the problem. We will. Eventually.

Its the percentage of light energy that will be converted into electricity. Say for example a panel recieves 1000 Watts of solar irradiation. 27% efficiency panel would convert 270 W of that into electricity.

Frederic Pouyot (5 months ago)
Efficiency of modules alone is not that important. I suggest you do a video on cost efficiency, which compares the efficiency versus the cost over the useful life of modules. Cost per kWh over the life and ROI are best measures of cost effectiveness. People buy houses even when much higher cost than rent if annual cost can save versus rent and provides additional benefits and level of control

it's not as much about the solar panels anymore as about the batteries. also what's the point of the 2% extra "efficiency" if it doubles the price for the same wattage: VBHN330SJ53 206.9pound/330w SPR-X21-345 572.6eur/345w
Anders Bentsen (6 months ago)
This makes no sense at all - like yoppindia say below - only thing we have to look at is cost per watt, and all of these examples is expensive and have close to zero benefits compare to low thin film or solar paint. There is thin film on market today with pretty good effiency who can be made (if they want to sell that cheap) at maybe 15dollar for 50watt day and night and they are transparent so you can add it on your windows or roofpanels without you can see it. Besides we should see perovskite solar paint within 3-5 years so you just paint your walls at house .

Been hearing about these solar cell "breakthroughs" for many years, but none of it ever trickles down to the consumer in the form of being cheap enough to compete with the price of traditional fuels like oil and gas. You want to impress me? Give me solar panels that will produce at less than a dollar per watt.
Ian Murray (4 months ago)
My panels cost just under $200 each, and each can generate up to 325 watts - is that less than 1 dollar per watt? Today each one (I have 22) generated 1.5 kWh - south facing, in the UK, in March. The whole system will take about 10 years to pay for itself because the UK is cloudy, then every watt will cost nothing at all.
