Why Does My Solar Panel System Need Periodic Maintenance and Cleaning?

  • Why do solar panels need periodic cleaning?
    Over time, dust, debris and sediment build up on the surface of the solar panel. This acts as a barrier between the light, and the solar panel, decreasing the amount of light that gets to the panel. Because less light gets to the panel, it produces less power than it would if it were clean.
  • Doesn't rain clean the panels?
    Unfortunately rain does not clean solar panels for you. In fact, rain often leaves behind its own residue and over time will build up on your panels. In the same way you need to clean your cars windows during the rainy season, you need to clean the surface of your solar panels to ensure all the light gets to the collector.
