Solar Panel Cleaning in West Mersea
On Mersea Island the sea is never far away, so salt reaches solar panels right across West Mersea and East Mersea, not just on the waterfront. We clean island panels with pure water, so the glass is left clear and streak-free.
The builder on this page calculates your cost from the number of panels.

Why island panels need more care
Salt dries onto the glass as a thin film. It scatters light and holds dust and pollen, so output drops slowly rather than all at once, and many owners only notice when they compare this year’s figures with last year’s. Gulls and waders are everywhere on the island, and their droppings add dark spots that shade the cells.
Homes near the beach huts and the boats get the most salt. Bungalows and family homes inland are more sheltered, but even they collect a salty film, and in East Mersea, among the farmland, field dust is added to the mix.
How often island panels need cleaning
Most Mersea homes are well served by two cleans a year; homes well inland may manage with one. Homes facing the open water collect salt fastest, so a clean in spring and another after the autumn gales keeps output steady through the year.
Bungalows, family homes and outbuildings
Many island homes are bungalows, where panels sit on low roofs within easy reach and the clean is quick. Panels on taller family homes are cleaned from the ground on poles in the same way. If you have panels on a garage, a workshop or an outbuilding as well, they count towards the same per-panel total, so it’s worth counting them all when you use the quote builder. Mersea’s clear skies mean clean panels generate well, which makes the effort worthwhile. Owners who track their figures often notice output creeping back up after the first clean of the year, once the winter’s salt has been rinsed away.
Why island panels need more care
On the mainland, salt is mostly a problem for homes right by the coast.
For most Mersea homes, twice a year keeps panels in good order.
Panels on homes facing the Blackwater see the most salt, carried in on the wind across open water.
How the clean works
Every panel is cleaned with purified water and nothing else. It carries the dirt off and leaves the surface clear. Stubborn spots are loosened first, so there’s no need to scrape. We’ll mention anything that looks wrong so you can contact your installer.

Lichen and moss on the frames
Where West Mersea panels sit in shade or damp air, moss and lichen can start to grow along the bottom edge of the frame, where water and dirt collect. Left alone, it creeps onto the glass. Regular cleaning keeps the edges clear.
