Solar Panel Cleaning

About Our Solar Panel Cleaning Service

Dirty solar panels produce less electricity. Bird droppings, algae, dust, pollen, and general atmospheric grime accumulate on panel surfaces and block sunlight from reaching the photovoltaic cells — studies consistently show that heavily soiled panels can lose 20–30% of their energy output compared to clean equivalents. At Oakleys Exterior Cleaning, we provide professional solar panel cleaning across Birmingham and the wider West Midlands, restoring panels to their optimal condition and helping you get the most from your investment. We use appropriate soft-wash methods and deionised water — the same technique recommended by panel manufacturers — to clean surfaces without scratching or damaging the glass or frame. Unlike harsh pressure washing at close range, our approach cleans effectively while protecting the panel's surface and warranty. We also inspect panels during cleaning and flag any visible damage or shading issues for your attention. Solar panel cleaning is recommended at least once a year in the West Midlands, where bird activity near rooftops and wet winters create ideal conditions for build-up. Panels facing south or south-west at a shallow pitch tend to self-clean less effectively in rainfall, making a professional clean particularly worthwhile.
