Solar panels work by converting sun-light that falls onto solar panels into electricity. The more light that hits a panel, the more power it will generate. During the course of time, when dust and other materials deposit on the solar panel surface, it essentially reduces the amount of light hitting the panel and so reduces its output.

Why do solar panels change color?
This reaction happens between the lamination materials (including EVA) and the oxygen in the environment. With prolonged exposure to sunlight, the EVA starts to oxidize and causes the surface to change color. Dirt, dust, bird droppings, and other environmental factors can also cause solar panel discoloration.
