Reports show that cleaning your solar array can yield more than a 30 percent increase in power production. According to the National Renewable Energy Laboratory (NREL), cleaning your solar panels can yield more than 30% in power production. Cleaning involves more than spraying your panels with water and scrubbing them down. First, cleaning the face of your panel should be done with proper cleaning solutions and equipment that will not compromise the panel's ability to produce power. For example, a brush can potentially 'etch' the panel glass which could permanently hinder it's ability to absorb the maximum amount of sunlight and produce optimum power.  In addition to the actual cleaning of panels, we perform an intimate physical inspection of the solar panels, attachment mechanisms and the area beneath the array to ensure all wires are secure and there is no sign of critter damage.
