Effect of Temperature on Solar Panel Efficiency |Greentumble
That is why all solar panel manufacturers provide a temperature coefficient value (Pmax) along with their product information. In general, most solar panel coefficients range between minus 0.20 to minus 0.50 percent per degree Celsius. The closer this number is to zero, the less affected the solar panel is by the temperature rise.
Understanding STC In Solar Panels: PV Test Conditions Explained
"What should the PV cell temperature be during a solar panel test?" The efficiency of solar panels depends on cell temperature. For example, a very hot 120°F solar panel will usually produce less electricity than at a milder 80°F temperature. Here is a quick solar panel temperature vs. efficiency chart that illustrates this relationship well.
