Solar panel cleaning in Didcot - restore lost efficiency

From £65. Your panels work harder after every clean.
Dirty solar panels are losing you money every day
Solar panels are an investment - but they only pay you back if they're clean. Dust, bird droppings, lichen and general grime build up on the panel surface and act as a barrier between the cells and the sun. Studies show that dirty panels can lose up to 25% of their energy generation capacity. That's money you're not getting back from your system.
In Didcot, Valley Park and Nobel Park, the majority of new-build homes now come with solar panels fitted - often as part of the government scheme that launched in 2023. If you're in one of these developments, now is exactly the right time to get them professionally cleaned before reduced output becomes a longer-term issue.
Should you clean your solar panels regularly?
Regular cleaning not only extends the lifespan of your solar panels but also maximises their energy output. Whether you have a few panels or a full roof installation, our service is designed to keep your solar panels looking great and functioning at peak efficiency.
How we clean solar panels safely
We use the same RO/DI purified water system we use for your windows - zero TDS, no minerals, no chemicals, no detergent. Pure water is applied with a soft brush head designed specifically for solar panel glass. It lifts debris gently without scratching the surface or voiding manufacturer warranties. No ladders needed for most standard installations - we work safely and quickly from the ground where possible.
