Coal to the UK rescue because solar panels are also underperforming in the summer • Increasing capacity with that?

Those who refuse to learn by reading end up learning by feeling. The UK is discovering that going coal-free is a lot easier said than done.
Summer temperatures in the UK have boosted demand for electricity, and as a result, the country has “started burning coal again for power generation for the first time in a month and a half,” the report said. Power outage news herequote Telegraph, June 13, 2023.
Apparently in summer weather the British solar panels refused to cooperate. Under the heat, their efficiency drops dramatically and so the country’s electricity needs cannot be met without coal power.
Coal to the rescue
“On Monday 12 June, a unit at the Ratcliffe-on-Soar coal-fired power station in Nottinghamshire, owned by German energy company Uniper, resumed in the UK after some time. vacation for several weeks. Another coal-fired power plant is kept on standby in case additional electricity demand arises in the early afternoon,” according to the report. power failure news. “Solar production last weekend was almost a third less than it was last weekend. This is due to high temperatures, exceeding 30 degrees Celsius in many parts of the country,”
Many technical disadvantages of solar energy
This represents another technical disadvantage that solar energy faces. Not only does it perform extremely poorly in the winter, when the energy demand is really high, but also in the summer when the temperature rises to around 30°C. The only time solar panels seem to work is when they’re not really needed.
Only work when you don’t need them
Solar panels are designed to work best when their surface temperature is 25″C. But in summer, their surface can easily reach 60 or even 70°C. As a rule, every temperature above 25°C means a 0.5% reduction in efficiency. That means at 65″C the panel loses 20% of its rated efficiency.
25% less output
“Alastair Buckley, Professor of Organic Electronics at the University of Sheffield, explains that higher temperatures have contributed to a large reduction in solar energy production. Compared to a cool, cloudy day, solar panels can be 25% less efficient,” writes power failure news.
In Germany, where nuclear power has been phased out, the country is dealing with energy troubles in its own great way: importing French nuclear power!
So green energy is working here in Europe!
