Why should I clean my Solar Panels?
The cells of a solar panel are protected from the elements by a layer of glass, similar to window glass. Because they are usually in a more horizontal orientation than a window, they are naturally subject to collecting and holding onto more dust and debris. Dirt, bird droppings, and leaves can all affect the ability of the sun’s rays to reach the cells. Some studies have estimated the energy loss from dirty solar panels can reach as high as 25%. This can obviously increase the amount of time it takes to recoup your investment.
