How Does Heat Affect Solar Panel Efficiencies?

For example, the temperature coefficient of a solar panel might be -0.258% per 1° C. So, for every degree above 25°C, the maximum power of the solar panel falls by 0.258%, and for every degree below, it increases by 0.258%. This means that no matter where you are, your panel may be affected by seasonal variations.
