Solar Panel Cleaning
Soft brush, pure water cleaning for solar panels - domestic, commercial, industrial and agricultural installations.
Dirty solar panels lose efficiency. Lichen, bird droppings, moss and atmospheric deposit build up on panel surfaces and reduce energy output. ProClean Access cleans photovoltaic panels using purified water and soft brushes - a method that does not damage panel surfaces or void manufacturer warranties. We reach arrays from our own access platforms wherever possible, and never stand on the panels themselves.
- Pure (deionised) water cleaning - streak-free, detergent-free, warranty-safe
- Soft brush heads - no abrasive contact with panel surfaces
- Platform access wherever possible - we never stand on the panels
- Domestic arrays through to large agricultural and commercial installations
- One-off cleans, or recurring annual and bi-annual maintenance contracts
- £10m public liability insurance

Frequently Asked
Heavily soiled panels produce noticeably less power; losses of 5% to 25% are commonly quoted, depending on how dirty they are. Cleaning removes the dirt that is blocking the light, so output recovers once the panels are clean.
Purified water and soft brushes are the cleaning method panel manufacturers generally recommend, so it should not affect a standard warranty. If in doubt, check your panel warranty terms or ask us.
For most domestic installations, once or twice a year is sufficient. Commercial arrays or those near agricultural/industrial areas may benefit from more frequent cleaning.
On pitched roofs we work from our access platforms rather than the roof itself, so the pitch is rarely a limiting factor. We check reach and positioning before the job.
