Solar panel cleaning? Compare professionals near you

On average you pay € 4 to € 8 per panel, with a minimum call-out. For an average home (10-16 panels) that comes to € 75-175 per visit. A pitched roof at height or heavy soiling makes it more expensive; a subscription lowers the price per visit.

The advice is once or twice a year, depending on your surroundings. Near trees, at the coast or with much bird nuisance, twice a year is wise; in an open, clean environment one spring visit is often enough.

Yes. Soiled panels can yield up to 10-25% less, depending on the soiling: a thin layer of dust matters little, bird droppings or a baked-on grime edge much more. A yield check shows how much it matters for you.

No, not really. Rain rinses off loose dust, but static grime, bird droppings, pollen and salt haze stay put: often as an edge along the frame where water lingers. That is why periodic cleaning remains necessary.

Panels at ground level or on a safely walkable flat roof you can do yourself: with osmosis water (demineralised water) and a soft brush, never with a pressure washer or detergent. On a pitched roof or at height it is work for a professional: the fall risk is not worth the price of a visit.

No, provided it is done right: with osmosis water and a soft brush the coating stays intact and the glass dries streak-free. What to avoid: pressure washers, aggressive detergents and scrubbing dry panels: that can scratch or attack the coating.

Yes. Submitting a request costs nothing and commits you to nothing. You receive up to 3 quotes and choose yourself: or no one, that's fine too. Prices and payment are arranged directly with the professional.

Yes. We verify Chamber of Commerce registration and business liability insurance before a company receives requests. Customer reviews factor into matching.

Affiliated companies carry business liability insurance: damage caused during the work falls under it. Always report damage directly to the company, and let us know if you cannot resolve it together.

Cheaper per visit (€ 65-140 instead of € 75-175 separately), automatically scheduled in spring and after summer, priority in the busy season and always the same professional who knows your roof. Mention it in your request.

Pigeons and gulls like nesting in the space under pitched panels. That means noise, droppings on the panels (and thus yield loss) and nesting material that can damage cables. Mesh or strips along the edges close that space without blocking ventilation.
