Solar panels perform optimally in moderate temperatures up to 77°F. Generally, a panel's efficiency degrades as temperature increases over 77°F. A solar panel's temperature coefficient indicates how well it performs in less-than-ideal conditions (such as temperatures above 77°F). The lower the temperature coefficient, the better.
Solar panel heat is the rise in temperature that solar panels experience when they absorb sunlight. The temperature increases due to the photovoltaic effect - the conversion of light into electricity - which is not 100% efficient and results in the generation of heat. The effects of this temperature rise on solar panels are multiple:
Solar panels do not necessarily stop working at a specific temperature. However, their efficiency may decrease as temperatures rise significantly above their optimal operating range. Solar panels typically have a temperature coefficient that quantifies their efficiency decline with increasing temperatures.

Temperature has a paradoxical effect on solar panels. You might think more heat equals more energy production, but it's more complex. High temperatures can actually reduce a panel's efficiency due to increased conductivity in semiconductor materials. A pivotal concept here is the temperature coefficient of solar panels.
