Solar Panel Cleaning

How Dirt Reduces Performance


  • Obstructs Light: Particles cover the photovoltaic cells, preventing sunlight from being converted into electricity.
  • Shading Effect: Even a thin layer creates shading, interrupting the electrical flow and cutting production.
  • Localized Hotspots: Thick spots, like bird droppings, can create resistance, leading to localized overheating and potential damage.

Impact on Energy Production


  • Significant Losses: Studies and real-world observations show efficiency drops of 10-25% (or more). Extreme cases have shown losses of over 50%.


When to Clean


  • Every 3-6 Months: A standard recommendation for general maintenance.
