Because of the increasing popularity of installing Solar Panels, Apex Window Cleaning is often being asked to clean therm.  Our expertise includes everything from large expanses of solar panels on commercial buildings with flat or pitched roofs to panels on a steep grade on the ground.  Leaves and/or heavy snow, excessive bird droppings, heavy dust, or locations that are directly next to or downwind from major highways, factories or agricultural fields are just some examples of conditions that may affect the panels’ efficiency up to 20% when left dirty.  We recommend a biannual cleaning frequency for your solar panels to properly maximize their potential.


Due to the fragility of most panels, we utilize deionized water-fed pole systems with special soft bristle brushes in order to prevent any damage.  We also avoid using any detergents or abrasive powders as they may streak or scratch the glass of the panels and cause shadows.  If the sun is beating down on the panels, water can quickly evaporate and likely just smear dirt around, so it helps to clean your solar panels on an overcast day, early in the morning or in the evening.


Often times, solar panels are on pitched roofs, especially if they are residential panels, so safety can definitely become an issue when considering cleaning them.  We ask that you please consider the conditions around you (weather, roof access, slickness, etc.) and avoid getting on your roof to clean panels.  recommend you leave climbing and rappelling to the professionals and give Apex Window Cleaning a call to schedule your Solar Panel Cleaning!
