Solar panels are gradually becoming popular, but many people will have more concerns, for example, will the solar panels overheat as the temperature rises every day as spring turns to summer? Will the solar panels be too cold when autumn and winter come?

If the surface temperature of the solar panel reaches this relatively high, the efficiency of the solar panel will decrease. But also keep in mind that solar panels are made of highly durable materials that can withstand extreme outdoor conditions – from freezing weather in the winter to blistering heat in the summer.

In addition, the exact temperature of your solar panel will depend on factors such as air temperature, geographic location, level of direct sunlight, and roof material. How an experienced solar charging panel manufacturer selects and installs solar panels to minimize any minimal impact of heat on solar panel efficiency.

Understanding the temperature coefficient of solar panels

If you want to understand how much energy a solar panel may produce, depending on the temperature outside, check the temperature coefficient on the data sheet provided by the manufacturer for your solar panel. The temperature coefficient tells you, as a percentage per degree Celsius, how much energy the solar panel will lose when the temperature increases by 1 degree above 25 degrees Celsius (77 degrees Fahrenheit).


As mentioned before, the standard test conditions (STC) for solar panels are AM=1.5, 25°C, 1000W/㎡. This is a standard test for solar PV modules, and the entire efficiency of solar panels is stable and efficient under these conditions.
