Restore your system's output
Solar Panel Cleaning in Sussex
Dirty panels can lose up to 25% of their energy output. We restore your system's efficiency using a pure water fed pole — no chemicals, no roof access needed, and fully warranty safe.
What's included
Every solar panel clean covers the full panel surface, frames, and edges. We use a pure water fed pole system — the same technology we use for window cleaning — which leaves panels spotless without any chemical residue that could affect performance.

The numbers that matter
Solar panels are a significant investment. Keeping them clean is one of the simplest ways to protect that investment and ensure your system generates what it should — year after year.
Sussex's mix of coastal salt air, tree pollen, and bird activity means panels here can get dirty faster than the national average. A regular clean keeps your generation figures where they should be.

Why clean your solar panels?
Rain alone isn't enough. Here's why a professional clean makes a real difference to your system's performance.
Restore lost output
Dirt, bird droppings, and algae can reduce panel efficiency by up to 25%. A professional clean restores output to near-factory levels.
Pure water method
We use a pure water fed pole system — the same technology as our window cleaning. No detergents, no chemicals, no risk to your panel coating or warranty.
Faster payback
Dirty panels mean your system takes longer to pay for itself. Regular cleaning keeps your energy generation — and your savings — on track.
Warranty safe
Our pure water method is non-abrasive and chemical-free, so it won't void manufacturer warranties or damage anti-reflective coatings.
Transparent pricing from £5 per panel
We price by the panel, so you only pay for what you have. Discounts apply for larger arrays. View our full pricing or get a personalised quote — no obligation.
Common questions
How often should solar panels be cleaned?
Once or twice a year is recommended for most Sussex properties. If you have trees nearby or your panels are at a shallow pitch (which doesn't allow rain to self-clean effectively), more frequent cleans will help maintain output.
Can't rain clean my solar panels?
Light rain removes loose dust but leaves behind dried mineral deposits, bird droppings, and sticky algae. These build up over time and significantly reduce efficiency — a proper pure water clean removes everything rain can't.
Will cleaning damage my panels or void the warranty?
No. We use a pure water fed pole system with no chemicals or abrasive materials. This method is widely recommended by panel manufacturers and won't affect your warranty.
Do you need access to the roof?
In most cases, no. Our water fed pole system reaches panels from ground level, which is safer for both our team and your roof. We'll let you know at the quote stage if your installation requires a different approach.
How much efficiency can I expect to recover?
It depends on how soiled the panels are, but studies show dirty panels can lose 15–25% of their output. Most customers see a noticeable improvement in their monitoring data within days of a clean.
Do I need to be home during the clean?
Not necessarily. As long as we have access to the panels and a water supply, we can carry out the work and let you know when we're done.
