With parts of the UK facing yet another spell of extreme heat, many solar panel owners will be watching their generation apps closely. Hot, bright weather can look like ideal conditions for home solar, especially if you’re running fans, air conditioning or other appliances during the day.
But while long summer days can help solar panels produce plenty of electricity, heat itself does not make panels work better. In fact, very high temperatures can slightly reduce the efficiency of the solar cells. The good news for most UK households is that this drop is usually modest, and a well-designed system can still perform strongly during a heatwave.
