How hot do solar panels get.

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. It can be less or more depending on weather. This tendency can even increase if they are installed in a desert location. 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. At that point for every degree increase in temperature above 77 degrees a solar panel loses efficiency by the rate of its temperature coefficient. Generally solar panels don t begin to lose efficiency until their temperature rises to 77 degrees.

However solar panels can get as hot as 65 c 149 f at which point solar cell efficiency will be hindered. Solar power is stable and consistent as well as renewable plus sunlight will not run out so if you take good care of your solar panels you don t have to find out how hot do solar panels get. 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.

In reality the panels can overheat especially in summer. Generally speaking solar panels are 20 c 36 warmer than the ambient temperature. Are solar panels hot to the touch. 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.
