What Are the Effects of Temperature on Solar Panel Efficiency?

In hot environments, PV panels tend to be less efficient due to the negative impact of high temperatures on the performance of PV cells. As the temperature rises, the output voltage of a solar panel decreases, leading to reduced power generation. For every degree Celsius above 25°C (77°F), a solar panel''s efficiency typically declines by 0.
