Wait....when it is too hot, solar panels do not work efficiently? But...isn't being in the sun their selling point? The left..get it wrong again....

It got a little hot in Britain......and because it got hot, their solar panels seem to have stopped working as efficiently?

Did anyone know this little factoid about solar power? You know before the smug leftists made fun of you for making fun of solar panels?

Besides having to compensate for the winds dropping away (uh-oh), who knew solar panels go to poop in the heat?

Britain has started burning coal to generate electricity for the first time in a month and a half, after the heatwave made solar panels too hot to work efficiently.
Did you know? I sure didn’t know. And they sure don’t tell you any of THIS in the fancy glossy handouts.

High temperatures over the weekend also reduced the amount of energy generated from solar panels. Output on Sunday was almost a third lower than a week earlier, despite temperatures climbing above 30 degrees celsius across large parts of the country.
Solar panels are tested at a benchmark of 25C. For every degree rise in temperature above this level, the efficiency is reduced by 0.5 percentage points.
The temperature level refers to the solar cell temperature, rather than the air temperature. In direct sunlight, the cells can easily reach 60 or 70 degrees.

Alastair Buckley, professor of organic electronics at the University of Sheffield, said: “Both days were largely sunny in the morning, so a good part of the reduction in output will be due to the efficiency reduction from higher temperatures on Saturday compared to Friday.

That’s the gist of this. And “solar” panels need their OWN cooling systems (!) in the desert. GTFO!

…In hot environments, PV panels tend to be less efficient due to the negative impact of high temperatures on the performance of PV cells. As the temperature rises, the output voltage of a solar panel decreases, leading to reduced power generation. For every degree Celsius above 25°C (77°F), a solar panel’s efficiency typically declines by 0.3% to 0.5%.
This decrease in efficiency can be significant in regions where temperatures rise dramatically during the day, such as deserts or tropical areas. In these environments, it’s best to select PV panels with a low-temperature coefficient. Also, installing cooling systems and ensuring adequate ventilation can help mitigate the effects of heat on solar panel efficiency.

Yep, when solar panels get too hot they all but shutdown. They also have about a 15 year life span. So we will be loading up the landfills with solar panels,, and one thousand pound EV batteries. Interestingly, Windmills also shut down when the wind is too strong. "Green Energy" will be the death knell for America. There is zero doubt about that.
 
On a small scale, like my house, solar works very well. My system is bigger than it needs to be to compensate for high temps. I have a couple panels over thirty years old, still test that they put out what they are rated for.
On a large scale, I do not know.
I will have power when most of you don't, and I haven't paid a power bill in over 25 years.

This has been a known limitation of solar panels since they were invented, but the leftist "environmentalists" and the solar manufacturing corporations covered it up and lied about it to sell more product.

All part of the plan......

Coal backup for solar?
Smartest thing they've done in years.

This claim has already been refuted in an earlier thread. The drop in output is trivial.

Once a panel reaches 25c, they lose 0.34% efficiency for every degree above that 25c.

As the heat came, people started turning on air con, fans etc.. which meant greater electricity demand, so they had to crank up a coal powered station for the grid to cope. The failing of a solar panel is that when it's producing, it can't be cranked up to meet more demand. The Achilles heal of renewables is storage.

Efficiency doesn't start dropping till temperatures get above 25C (77F). So at 32C (90F), efficiency would be down 7 x 0.34% or 2.38%. That is hardly "stopping". Additionally, as temperatures fall BELOW 25C - a far more common situation in the British Isles - panel efficiency RISES. See The Impact of Temperature on Solar Panel Efficiency: How Heat Affects Your Solar Energy System. for some objective discussion of this issue.

The transition from what we live with, and the infrastructure built for decades, and a century at least must be destroyed to start what you want. All housing from other eras is not compatible for what is pushed on us now. And Progs are pushing their glorious green energy agendas on that.
 
Solar dont work, people argue data from as designed, not after they have been used.

Solar cells are no different than micro chips. Some of us that are educated beyond the, Sky is Falling, childrens book know that fans and heat sinks cool computer chips.

the more you use it, the hotter it gets, cool it or destroy it

Solar PV does work and they work in hot environments, just not as well as in cold environments. Keep in mind that solar cells do not contain billons of transistors, diodes, junctions and layers. Far less locations for current-induced overheating and thermal failures. The efficiency loss due to temperature is more than overcome by the increased insolation in tropical latitudes.

Wait. So the coal plants had to be fired up NOT because of a lack of output by solar (which was trivial) but because of the rather large increase in demand?

Oh

To what post are you replying?

I have a good friend who is an executive with one of the US largest power companies. His company put in many of these solar farms. I have mentioned in other posts the reasons why and it has nothing to do with their ability to produce efficient electrify.

He tells me the maintenance on these solar arrays is a nightmare. Nobody is talking about most of them having to be replaced every three or four years and the degrading of the power output. Terrible technology.
