Counterintuitively, if the panels become too hot, they will actually produce less electricity. Overheating reduces solar panel efficiency, impacting the percentage of sunlight the panel can transform into power. Read on to learn more about how temperature affects solar panel efficiency and ways to mitigate the effects.
According to Solar Energy UK, solar panel performance typically falls by about 0.34 percentage points for every degree that the temperature rises above 25C, although that varies between different panels.
So, for every degree above 25°C, the maximum power of the solar panel falls by 0.258%, and for every degree below, it increases by 0.258%. This means that no matter where you are, your panel may be affected by seasonal variations. However, the temperature coefficient also demonstrates that efficiency increases in temperatures lower than 25°C.
Solar panels can get quite hot, especially under direct sunlight. The exact temperature that solar panels can reach depends on various factors, including ambient temperature, sunlight intensity, panel design, and ventilation. On a sunny day, solar panels can heat up to temperatures ranging from 25°C (77°F) to 65°C (149°F) or even higher.
Climate and average temperature are the primary culprits. If you live in a location with a hot or humid climate, like Texas or Florida, you likely deal with high average daily temperatures. As a result, your roof (or anywhere your panels are) is probably far from cool. And that means it might be too hot for solar panels.
Let’s get one thing straight before we go any further: Most solar panels have a negative temperature coefficient. This means that as a solar panel’s temperature rises, its efficiency decreases (they’re negatively correlated). In other words, it’s highly unlikely you’ll have (or buy) a solar panel that works better when it gets too hot.
