While extreme heat can reduce a solar panel’s efficiency, they continue to function effectively, even in high temperatures. In the UK, around 40% of a solar panel system's energy is generated in the summer, showing its strong performance in warmer months.
This gap is usually less extreme if you have a south-facing array, with 36% of your annual solar energy produced from May to July, and 12% generated from November to January. The most common ways to keep solar panels cool in hot weather involves cold air or spraying the panels with water.
Solar panels thrive in sunny conditions, but intense sunlight can lead to higher temperatures, which can diminish their efficiency. However, the level where solar panels stop being effective is around 85°C, which is far above the hottest UK summer temperatures. What happens when a solar panel gets too hot?
This coefficient refers specifically to the panel's temperature, not the surrounding air temperature. So, even if it's 25°C outside, the panel itself will likely be hotter. It's not until the panels reach extremely high temperatures – around 85°C – that solar panels might stop generating electricity altogether.
While it’s correct that solar panels can be less efficient in hot temperatures, this reduction is relatively small. According to Solar Energy UK, solar panel performance falls by 0.34 percentage points for every degree that the temperature rises above 25°C.
Solar panels work very well in a heatwave. They generate much more electricity when it’s hot than on cloudy days, assuming the heatwave comes with relatively clear skies. Solar panels do, unfortunately, lose a small fraction of their efficiency with every degree that their temperature – not the air temperature – creeps over 25°C.
