Solar panel cleaning for, maximum output.
Professional pure water solar panel cleaning across East Kent — restore your system's efficiency, protect your investment and get the output your panels were designed to deliver.
ABOUT THIS SERVICE
Dirty solar panels cost you money every day.
Solar panels are designed to operate at peak efficiency only when clean. Panels are exposed year-round to bird droppings, lichen, algae, pollen, dust and general grime — all of which block sunlight from reaching the photovoltaic cells and reduce the amount of electricity your system generates.
Rain alone is rarely enough. It can rinse away loose dust, but it cannot remove bird fouling, hardened lichen or organic growth — and these are the contaminants that cause the greatest drop in output. Regular professional cleaning is a great way to keep your panels performing at the level they were designed for.
We use the same pure water fed pole system as our window cleaning service — pure water delivered through water-fed brush heads — to clean panels safely from the ground, ladder, or access equipment without stepping on the roof or risking any damage to the panel surface or seals.
HOW WE CLEAN
Safe,effective clean for panel efficiency.
Water-fed pole systems with pure water
We use the same pure water that has gone through a reverse osmosis and deionisation process as our window cleaning service. Water is delivered through water-fed brush heads on extendable poles, allowing us to clean panels thoroughly from the ground, scaffolding, high-access equipment, or a ladder where possible.
Pure water leaves no mineral residue on the panel surface, meaning after we’ve vigorously scrubbed and washed down the panels, they dry streak-free, and the glass stays cleaner for longer after each visit.
No harsh chemicals or high-pressure
We do not use chemicals, detergents, or high-pressure washing on solar panels. Chemical residues can degrade the anti-reflective coating on some panel glass, and high pressure risks damaging seals, frames and cell connections.
Our water-fed brush head, pure water cleaning method, is fully compliant with solar panel manufacturer guidelines and will not affect your panel warranty. An important consideration that is often overlooked when choosing a cleaning provider.
WHY IT MATTERS
Five reasons to keep your panels professionally clean.
Recover lost output immediately
Seriously soiled or dirty panels can lose between 15% and 25% of their efficiency compared to clean panels, according to multiple independent studies. A single professional clean can recover that lost output in one visit, with results visible in your generation readings straight away.
Bird droppings cause disproportionate damage
Even a small patch of bird fouling can shadow individual cells and cause a drop in output across the entire panel — and in some cases across the entire string. Because of the angle of many roof-mounted panels, droppings accumulate and do not wash away with rain. Regular cleaning removes this consistently.
Protect your warranty
Many solar panel manufacturers and installers specify regular professional cleaning as a condition of their warranty. If your panels develop a fault and you cannot provide evidence of regular maintenance, your warranty claim may be rejected. Professional cleaning with a documented service record protects that cover.
Maximise your return on investment
Solar panels represent a significant investment. If your system is operating at 80% efficiency due to soiling, you are effectively losing 20% of the return your installation was designed to generate. Regular cleaning is low-cost relative to the value of the output you recover.
Cleaning reveals maintenance issues early
A professional clean also provides an opportunity to identify any visible damage, loose connections, cracked glass or signs of physical deterioration — issues that, caught early, can be addressed before they affect performance or safety.
