Contact UsWhat is the Maximum Temperature a Solar Panel Can Withstand?
When the temperature of the solar panel gets too hot, the efficiency of the panel decreases. The reason for this is that when a solar panel gets hot, the electrons in the semiconductor material that make up the solar panel get excited and start moving around more. This increases resistance within the solar panel and causes it to lose efficiency.
