Solar Panel Cleaning

About Our Solar Panel Cleaning Service

Dirty solar panels can lose up to 25–30% of their energy-generating efficiency. Dust, bird droppings, pollen, tree sap, lichen, and general atmospheric grime create a film over the panels that blocks sunlight and reduces output. Our professional solar panel cleaning service uses pure, deionised water and soft brushes to gently but thoroughly clean your panels without scratching the glass or damaging the anti-reflective coating. Regular cleaning ensures you’re getting the maximum return on your solar investment.

Our Process

1. Assessment: We assess your solar panel array, noting the panel type, angle, accessibility, and level of soiling.
2. Pure water preparation: Our filtration system produces completely deionised pure water — free of minerals and impurities that could leave deposits on your panels.
3. Gentle cleaning: Using soft-bristle brushes on telescopic poles, we gently scrub each panel to remove all dirt, droppings, and organic build-up.
4. Thorough rinse: Each panel is rinsed with pure water, which dries naturally to a spot-free, residue-free finish.
5. Post-clean check: We inspect all panels after cleaning and provide recommendations on cleaning frequency based on your location and surroundings.

Pricing Guidance

Solar panel cleaning is very affordable relative to the energy gains. Typical prices for a domestic installation (8–16 panels) range from £50–£100 per clean. Larger commercial installations are quoted individually based on the number of panels and access requirements. We recommend cleaning at least once or twice per year, with more frequent cleaning if you’re near trees, busy roads, or in an area with high bird activity.

Why Clean Your Solar Panels?

Many solar panel owners don’t realise how much energy they’re losing to dirt and grime. Rain alone is not enough to keep panels clean — it actually creates streaks that dry onto the surface and attract more dirt. Bird droppings in particular create ‘hot spots’ that can permanently damage panel cells if left untreated. Professional cleaning with pure water is the manufacturer-recommended method and won’t void your warranty. At Cleaner Surrey, we understand the technology and treat every panel with care. The cost of a professional clean typically pays for itself within weeks through increased energy generation.
