How Hot Do Solar Panels Get

Generally solar panels don t begin to lose efficiency until their temperature rises to 77 degrees.

How hot do solar panels get.

Generally speaking solar panels are 20 c 36 warmer than the ambient temperature. If you have any other thoughts on how hot do solar panels get let us know in the comments below. While this would be uncomfortable to touch it is unlikely to give you any serious burns. Time to do some math.

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. In the summer solar heaters are rarely used as unheated pools can reach into the upper 80 s naturally. The good news is that the panels are designed to withstand temperatures up to 25 degrees celsius while maintaining an optimal level of performance. In reality the panels can overheat especially in summer.

Panasonic s efficiency rate is 21 6. However solar panels can get as hot as 65 c 149 f at which point solar cell efficiency will be hindered. Install factors like how close the panels are installed to the roof can impact the typical heat of your solar system. However solar panels can get as hot as 65 c 149 f at which point solar cell efficiency will be hindered.

For example the ambient temperature in the desert can reach 113 which this means solar panels in this climate can reach 149. This tendency can even increase if they are installed in a desert location. It can be less or more depending on weather. The short answer you have been waiting for is that solar heated pools with ideal systems usually reach 8 12 degrees above an unheated pool.

At that point for every degree increase in temperature above 77 degrees a solar panel loses efficiency by the rate of its temperature coefficient.
