Solar Panel Cleaning in Dorset to protect your investment.
Solar panels are a long-term investment in your property. Professional cleaning removes the build-up that reduces performance, safely and without harsh chemicals.
Why Clean Solar Panels At All?
Your solar panels rely on sunlight reaching the surface of the glass. Over time, contamination can reduce the amount of light reaching the cells, and independent studies put the output loss from soiled panels at 5–15%, which has a direct impact on your energy costs.
Professional cleaning helps remove dust, dirt, pollen, bird droppings, algae and general environmental debris. Keeping your panels clean also gives you the opportunity to visually inspect them for any obvious signs of damage or excessive build-up.
- Pure water and soft brushes only, the manufacturer-approved method

How Often Should Solar Panels Be Cleaned?
There isn't a single answer for every property, but solar panels do require specialist care. Some installations may benefit from more frequent cleaning than others depending on their location and the surrounding environment.
Our cleaning methods are designed specifically for solar panels and use purified water together with professional equipment to clean safely without leaving residues behind. We never use abrasive cleaning products that could damage the surface of your panels.
Our 4-Step Panel Clean
how it worksArray Check
We assess access, panel condition and anything fragile before a brush goes near the roof.
Pure Water Wash
Soft brush and filtered pure water lift grime without detergents.
Frame Detail
Frames and lower edges, where run-off grime concentrates, are cleaned so they don't re-streak the glass.

Solar Panel Cleaning Questions, Answered
How much does solar panel cleaning cost in Dorset?
Every array is quoted individually based on panel count and access, free and without obligation. Pairing the clean with window or gutter cleaning can often prove most cost effective.
Doesn't rain keep solar panels clean?
No. Rain rinses loose dust but leaves mineral film, pollen, lichen and bird mess where they were, usually concentrated along the bottom edge.
Will cleaning void my panel warranty?
Solar panel cleaning will not void your warranty, but it's critical to use approved methods and follow manufacturer guidelines. We never use pressure washing, harsh chemicals, abrasive cleaners or caustic detergents, which can damage panels.
How much output will I actually get back?
Independent studies put soiling losses at 5–15% for UK domestic arrays, and more where bird mess shades individual cells.
How often should panels be cleaned?
There isn't a specific answer. Some installations benefit from more frequent cleaning than others depending on their location and the surrounding environment.
Is it safe? Do you walk on the roof?
We never walk on panels, and most arrays are cleaned from ladders, scaffold towers or ground-based poles without stepping on the roof at all.
