Can solar panels get too hot?
When solar panels get hot, they become less effective at generating electricity. This is because as temperature increases, electrical resistance increases too. This means that as a solar panel gets hotter, more and more of the electricity it generates is lost as heat. It’s possible to know exactly the effect of heat on your solar panels by checking its specification sheet and looking up the power temperature coefficient. It’s expressed as a percent reduction of efficiency for every one degree Celsius increase in temperature.
