Solar panel cleaning
Dirty solar panels can lose up to 10% of their output. Our professional cleaning restores maximum yield — safely and without scratches.
Why have your solar panels cleaned?
Dust, pollen, moss, bird droppings and air pollution build up on the glass and block sunlight — and every blocked ray is electricity you don't produce. A professional clean can lift output by up to 10%, and with today's digital meters that extra production is power you use yourself instead of buying it back from the grid.
How often should they be cleaned?
Usually once a year, ideally in spring after winter grime. In leafy, rural or industrial areas, twice a year is recommended. Some manufacturer warranties also expect regular, documented maintenance.
