If you haven’t had your solar panels cleaned, then dirt, pollution and bird droppings are affecting how much electricity they produce.  According to the National Renewable Energy Laboratory, productivity losses average 25% on dirty solar panels, while individual installers have reported losses as high as 30%.  A simple solar panel cleaning will restore performance to like new.  With our years of solar panel cleaning experience, Gilland Window Cleaning can help!
