What does solar panel cleaning cost in 2026?

All price guides in one place: per panel, per property type and per subscription: plus the 6 factors that drive the price.

Solar panel cleaning in 2026 costs on average € 4 to € 8 per panel, with a minimum call-out. For an average home with 10 to 16 panels that means € 75 to € 175 per visit. The standard method is osmosis water (demineralised water) with a soft telescopic brush: streak-free and without detergents that attack the coating.

The price depends on six factors: the number of panels, roof pitch and working height (a pitched roof at height requires climbing work or a lift), accessibility, the level of soiling (bird droppings and baked-on grime take more time than dust), the choice between one-off and subscription, and the route: several roofs in one street lower the price per home.

If you'd rather not think about it again, a cleaning subscription is cheaper per visit: € 65 to € 140 on a yearly contract, because the professional adds your roof to a fixed route. If you have pigeons or gulls under the panels, expect € 195 to € 450 for bird proofing including nest removal.

Always request multiple quotes: differences between companies run high for exactly the same job. Set a quote against the price index before you agree to it.
