Dust, pollen and bird mess quietly eat into your generation. Pure rainwater brings the panels back without risking the coatings or the warranty.
Panels sit at an angle facing the weather, so they collect everything the weather throws at them. Left alone, a dirty array can lose a surprising chunk of its output. Cleaning typically recovers a noticeable share of that generation, and on larger arrays the difference shows up on the meter.
The method matters. We use soft brushes and de-ionised pure water only, the same water we put on your windows. No detergents, no abrasives, nothing that could mark the anti-reflective coating or give a manufacturer an excuse to question the warranty.
Most customers book it as a yearly or twice-yearly visit. If you're having the gutters done anyway, bundle the two: the same kit covers both jobs and the price comes down accordingly.
Clean panels generate more. Simple as that.
Soft brushes and pure water. Coatings and seals untouched.
From a 4kW household roof to large commercial installations.
Ground-based poles reach most arrays without roof access.
Same visit, same kit, better price.
Yearly or twice-yearly visits, booked in advance.
If the answer is "never", there's probably free generation sitting under the grime. Ask us for a price.
