Solar Panel Cleaning

Name: RSG Clean
Telephone: 07746 911806

Maximise your energy yield with professional pure water cleaning. No detergents, no streaks, no risk to your panels.

Why Clean Your Solar Panels?

Winter leaves its mark on your panels. Dust, soot, pollen, bird droppings and melted-snow residue reduce output by up to 15–20%. When spring arrives and your system should be generating more, dirty panels hold it back.

Rain alone doesn't clean panels effectively — it often makes things worse by leaving mineral deposits that bake on in the sun.

Our pure (deionised) water method cleans without detergents and dries without streaks — maximising your energy yield and protecting your investment.

Our Method

Pure Water Rinse

Deionised water fed through carbon fibre telescopic poles — reaches rooftop panels safely from the ground.

Soft Brush Agitation

Gentle rotating brush loosens baked-on grime without scratching panel surfaces or damaging anti-reflective coatings.

Spot-Free Dry

Pure water evaporates leaving zero mineral deposits, zero streaks — just clean, efficient panels.

Frequently Asked Questions

How much efficiency do dirty panels lose?

Dirty solar panels can lose 15–20% of their output, especially after winter when dust, soot, pollen, and bird droppings accumulate.

Is pure water safe for solar panels?

Absolutely. Deionised (pure) water is the manufacturer-recommended cleaning method. It leaves no residue, no streaks, and won't damage panel coatings.

How often should panels be cleaned?

Once or twice a year is ideal — spring (after winter grime) and autumn. More often if you're near trees or have bird problems.

Will cleaning void my warranty?

No. Pure water cleaning with soft brushes is the safest method and is endorsed by most panel manufacturers.
