Keeping panels clean in dusty weather

Rinse panels with plain water every 2–3 weeks in dry months, early morning or evening. Avoid detergent and hard brushes that scratch the glass.

Dust is the most common reason a healthy solar system produces less than it should. The good news is that keeping panels clean is simple and cheap.

Why dust matters

Panels make power from the light that reaches the cells. A layer of dust, bird droppings or leaves blocks some of that light, and output drops with it.

How often to clean

  • Every 2–3 weeks in dry, dusty months
  • Less often in the monsoon, when rain does much of the work
  • After a dust storm, or if you see droppings on the glass

How to clean safely

  • Clean early in the morning or in the evening, when the glass is cool
  • Use plain water and a soft cloth, sponge or soft mop
  • Do not use detergent, hard brushes or a pressure washer
  • Never stand or lean on the panels

When to call for service

If output stays low after cleaning, your inverter shows an error, or you see cracks or burn marks on a panel, do not try to fix it yourself. Leave the wiring alone and book a service visit.
