Factors influencing the frequency of cleaning solar panels

  • Rainwater: While rainwater itself is relatively clean, it can carry various particles and pollutants from the atmosphere as it falls. These particles include dust, pollen, bird
    droppings, and other airborne contaminants. When rainwater evaporates or dries on  the surface of the solar  panels, it can leave behind a thin film of dirt or residue, particularly if the rainwater was not enough to fully wash away the particles. Over time, this build-up can reduce the efficiency of the panels by blocking sunlight from reaching the photovoltaic cells.
  • Location: Frequency depends on local conditions like dust or bird activity.
  • Efficiency Loss: Clean every few months to a year when efficiency drops.
  • Seasonal Factors: During dry or high pollen seasons an accumulation of Dust and dirt
    can occur.
  • Professional Inspection: Combine with regular maintenance checks.
