Pure-water pole cleaning
Deionised water and soft heads on telescopic poles, from the ground or roof, leaving no residue.
Solar panel cleaning
that recovers lost output.
Scheduled or one-off cleaning that removes the soiling that reduces generation, without chemicals or pressure washing. Trained technicians clean with pure water, pole-fed and mechanical systems and safe access, on commercial rooftops, carports, ground-mounts, public estates and homes, whoever installed the system.

01. Who this page is for
Soiling costs generation
Soiling costs generation
and is easy to miss.
This page is for anyone responsible for a solar array: facilities managers, estates teams, landlords, farmers and homeowners. UK rain cleans panels to a degree, but dust, pollen, bird droppings, moss, lichen and industrial or agricultural deposits still build up. This is especially true on low-pitch and flat-roof arrays, near trees, on farms and beside busy roads. Generation drops, and it is easy to miss until the monitoring shows it.
Mechanical cleaning feeds deionised pure water through telescopic poles with soft rotating or brush heads. It lifts soiling without chemicals or scratching, and leaves no residue to attract the next layer of dirt. It avoids the chemicals and pressure washing that can damage panels or put a manufacturer’s warranty at risk.
We plan safe access for every site, from ground-level pole work to roof access with edge protection. Each clean includes a visual inspection, so we can report loose fixings, damaged panels or nesting at the same time.

Cleaning that
Cleaning that
protects your investment.
Mechanical brush systems
Rotating brush heads for larger commercial, carport and ground-mount arrays, where speed and efficiency matter.
Safe access
Risk assessment, edge protection and access equipment planned for every site before we arrive.
Inspection included
A visual check for damaged panels, loose fixings, cable wear and nesting, reported after every clean.
Scheduled programmes
Annual or seasonal cleaning, timed with planned maintenance visits and guided by monitoring data.
Bird & pest protection
Mesh and deterrents fitted where nesting under panels is a recurring problem.

07. Cleaning FAQs
Your cleaning
Still have a question?0330 043 1047 Your cleaning
questions answered.
How often should solar panels be cleaned?
It depends on pitch, location and surroundings. Many commercial and rural arrays benefit from an annual clean and some need more. Monitoring data tells us when output is dropping.
Will cleaning damage the panels?
Not with the right method. We use deionised pure water and soft heads with no chemicals or pressure washing, which avoids scratching the glass or leaving residue.
Is solar panel cleaning worth it?
Soiling reduces the light reaching the cells, so heavily soiled panels generate less. Low-pitch, shaded, rural and roadside arrays are most affected. Monitoring data and an inspection show whether soiling is affecting your output before you commit to a clean.
Doesn’t rain keep panels clean?
To a degree. Rain washes off some dust, but bird droppings, moss, lichen and agricultural or industrial deposits build up regardless, especially on low-pitch and flat-roof arrays where water does not run off quickly.
How do I know my panels need cleaning?
Visible dirt, droppings or moss on the panels, or a fall in generation that monitoring cannot explain by weather or faults. If you are unsure, an inspection visit will tell you.
Can you clean a system another installer fitted?
Yes. We clean, inspect and maintain solar PV systems from any installer.
Do you clean domestic arrays?
Yes, from single homes to housing portfolios, with access planned safely for each roof.
Can cleaning be part of a maintenance contract?
Yes. We schedule cleaning alongside planned maintenance visits, monitoring and fault response in one operations and maintenance plan.
