How Hot Do Solar Panels Get

However solar panels can get as hot as 65 c 149 f at which point solar cell efficiency will be hindered.

How hot do solar panels get.

While this would be uncomfortable to touch it is unlikely to give you any serious burns. For example the ambient temperature in the desert can reach 113 which this means solar panels in this climate can reach 149. In the summer solar heaters are rarely used as unheated pools can reach into the upper 80 s naturally. In reality the panels can overheat especially in summer.

Generally solar panels don t begin to lose efficiency until their temperature rises to 77 degrees. Home solar panels are tested at 25 c 77 f and thus solar panel temperature will generally range between 15 c and 35 c during which solar cells will produce at maximum efficiency. At that point for every degree increase in temperature above 77 degrees a solar panel loses efficiency by the rate of its temperature coefficient. Panasonic s efficiency rate is 21 6.

Are solar panels hot to the touch. If you have any other thoughts on how hot do solar panels get let us know in the comments below. It can be less or more depending on weather. This tendency can even increase if they are installed in a desert location.

Time to do some math. Install factors like how close the panels are installed to the roof can impact the typical heat of your solar system. Home solar panels are tested at 25 c 77 f and thus solar panel temperature will generally range between 15 c and 35 c during which solar cells will produce at maximum efficiency. However solar panels can get as hot as 65 c 149 f at which point solar cell efficiency will be hindered.

The good news is that the panels are designed to withstand temperatures up to 25 degrees celsius while maintaining an optimal level of performance.
