Do I need to clean my solar panels?

The answer is definitely yes, especially if you don't get a lot of rain or you live in a desert terrain or area with more dust or particles that can get in the way of the photovoltaic cells. Did you know that the solar energy in DC is converted to home energy AC not through heat but through the actual solar irradiation ie the sunlight exposure? In fact, overheated solar panels that typically happen when you install those ridges to make them have that Tesla Solar panels.

The accumulation of dust on solar panels or mirrors is a real issue, since it can reduce the output of photovoltaic panels by as much as 30 percent in just one month — so make sure that you are always cleaning them atleast once a month, or depending on if you are in a terrain with more dust particles, pollen, etc. 2-4 times a month.
