Do Solar Panels Work Less Efficiently at Certain Temperatures?
Another way of looking at this is that solar cells produce power by the electrons moving from one energy state (rest) to a higher one (excited). When a solar panel is hot, the difference between the rest state and the excited energy state is smaller, so less energy is created. The opposite happens when a solar panel is cooler.
