WHY CLEAN? 

  • Dirt and debris reduce the amount of sunlight that is able to penetrate solar cells. 

  • Bird droppings, pollen, and other organic matter can create hotspots.

  • Crud can cause permanent damage to the solar panel.

  • Heavy pollution or frequent rain.

Lifespan Dependency 

  • Environmental conditions

  • Quality of the panels

  • Manufacturer

  • Maintenance

DATA 

  • On average, most solar panels experience a decrease in efficiency of around 0.5 - 1% per year.

  •  This means that after 25 years, a solar panel that started with an efficiency rating of 20% would have an efficiency rating of around 7.5% lower, or approximately 12.5%.
