How Dust Affects Solar Panel Performance

How much efficiency is lost due to dust on solar panels? In Ahmedabad and Gujarat, soiling loss of 20–35% within a few weeks without cleaning is common — especially near industrial belts.

What is soiling loss?

Dust, pollen, pollution and bird droppings form a film that scatters and blocks sunlight. Less light reaches the silicon cells, so fewer electrons flow — and your inverter reports lower daily kWh.

Real cost of dirty panels

A 10 kW home system that should generate ~40 units/day can drop to ~28–32 units when heavily soiled. At ₹8/unit, that is thousands of rupees lost every month — far more than the cost of professional cleaning.

Does cleaning solar panels increase output?

Absolutely. Removing dust restores light transmission. Pair cleaning with demineralized water so you do not leave hard water stains that create a second layer of loss.
