Does temperature affect a solar panel's efficiency and output?

One question that frequently comes up is whether temperature affects a panel's efficiency and output. Well, the answer is yes – temperature plays a significant role. To understand why, we need to go back to basics. Solar panels work by converting sunlight into electricity through photovoltaic (PV) cells.

How does temperature affect PV panels?

When the temperature is above or below this range, the panel's output starts to decline by up to .5% on average. During high temperatures, the panel's temperature increases, leading to increased resistance within the PV cells. The resistance increases the amount of heat generated, leading to a further reduction in efficiency.

How do I choose a solar panel for a hot climate?

When considering solar panels for hot climates, pay attention to the temperature coefficient. This tells you how much efficiency the panel loses for every degree above the standard test temperature of 25°C (77°F).
