In reality, solar panels generate electricity from light, not heat. As temperature rises, the voltage output of the panel decreases. Although the drop is small, it becomes significant during long, hot summer days.

''The optimal operating temperature for a solar panel is below 25 °C.'' When temperatures rise, so does the temperature of the cells, which can reduce their electrical output.
