The average temperature coefficient for a solar panel is -0.32%/°C, which means for every degree above 25°C, a solar panel''s output falls by a miniscule 0.32%. However, even if your solar panels were to reach the dizzying heights of 50°C, they would still be operating at roughly 92% of their original capacity - not a very significant loss at all.
