Commercial Solar Panel Cleaning Services
Pure water fed cleaning for rooftop and ground-mounted commercial solar arrays — RAMS provided, fully insured, no subcontracting.
Commercial Solar Panel Cleaning for Maximum Energy Output
Investing in commercial solar is a smart move — but soiled panels can lose 10–25% of their energy output, directly cutting your return on investment. Dust, bird droppings, lichen and atmospheric pollution all build up over time, and rain alone doesn't clear them.
G.B Cleaning Services provides professional commercial solar panel cleaning across Norfolk, Suffolk, Cambridgeshire and the wider East of England. We work with rooftop arrays on warehouses and factories, ground-mounted commercial installations, agricultural building solar, and carport canopy systems of all sizes.
Why Choose us?
At G.B Cleaning, your solar panels are cleaned using our pure water fed pole system — deionised water that leaves no mineral deposits, no streaking and no chemical residue that could affect panel coatings or manufacturer warranties. We use soft to medium bristle brushes to remove dirt and grime without scratching the glass surface.
For severe or stubborn lichen, an acrylic scraper is used to lift the growth without damaging the glass. A final thorough rinse removes any remaining debris, returning panels to their original condition and restoring full light transmission.

The Importance of Solar Cleaning
Commercial solar arrays are a significant capital investment — and soiling is the single most controllable factor affecting their ongoing output. Dust, bird droppings, pollen, algae and atmospheric pollution all reduce the amount of light reaching the solar cells, cutting generation.
Regular professional cleaning restores full output, protects the panel surface from long-term staining and lichen damage, and ensures your system performs to its rated capacity throughout its operational life. For commercial operators, the cleaning cost is typically offset many times over by restored energy generation.
When to Consider Solar Panel Cleaning?
- Reduced energy output — if your monitoring system shows a drop in generation that can't be explained by weather, soiling is the most common cause. Cleaning typically restores full output within days.
- Bird activity — bird droppings are particularly damaging as they create localised shading that causes hotspots, which can permanently reduce cell efficiency if left.
- Visible soiling — a film of dust, algae or lichen growth across the panel surface is a clear sign cleaning is overdue.
- New installation or post-construction — construction dust is among the most damaging contaminants for solar panels. New or recently extended installations should be cleaned before performance baselines are set.
- Scheduled maintenance — most commercial operators on larger installations clean every 6–12 months as part of a routine maintenance programme.

Commercial Solar Panel Cleaning — Frequently Asked Questions
How much does commercial solar panel cleaning cost?
Pricing is based on the number of panels, the installation type (rooftop, ground-mounted or carport canopy), access requirements, and whether you want a one-off clean or a regular maintenance schedule. We provide free site surveys and fixed-price quotes. Call 01362 685446 to arrange yours.
How much efficiency do dirty solar panels lose?
Studies consistently show that soiling reduces commercial solar output by 10–25%, depending on the location, local environment and time since the last clean. For a 100kW commercial array, that's potentially 10–25kW of generation being lost every hour of peak sunlight. Regular cleaning is one of the most cost-effective performance improvements available to commercial solar operators.
How often should commercial solar panels be cleaned?
Most commercial installations benefit from cleaning every 6–12 months. Arrays near agricultural land, busy roads, or in areas with heavy bird activity may need more frequent attention. We can advise on the right schedule after a site survey.
What method do you use to clean commercial solar panels?
We use a pure water fed pole system with soft to medium bristle brushes. Deionised pure water leaves no mineral deposits, no streaking and no chemical residue that could affect panel coatings or invalidate manufacturer warranties. For stubborn lichen, an acrylic scraper removes the growth without scratching the glass surface.
Will cleaning damage the panels or void the warranty?
No — when done correctly, professional cleaning does not damage panels or affect warranties. Our pure water fed method uses no chemicals and no abrasive materials. We avoid high-pressure water, which can force moisture into panel frames and junction boxes. If your manufacturer specifies a cleaning protocol, let us know and we'll work within it.
Can you clean large-scale or ground-mounted commercial solar arrays?
Yes. We have the equipment and experience to clean commercial arrays of all sizes, including large rooftop installations on warehouses and factories, ground-mounted commercial and agricultural solar farms, and carport canopy systems. We carry out a full site survey before any work begins to assess access and plan the clean safely.
Do you provide RAMS and site surveys?
Yes — method statements and risk assessments (RAMS) are provided as standard with every commercial solar cleaning job. We also carry out detailed site surveys before work begins. We do not subcontract; all work is carried out by our own trained team.
