Why Clean Your Solar Panels Yearly?
Rainwater alone cannot clean solar panels. Over time, air pollutants, lichen, dust and bird deposits build up, blocking solar radiation and costing you money.
Regain 10%–25% Power Output
Even a light layer of dust, traffic film or pollen noticeably degrades photovoltaic efficiency. Clean glass lets sunlight generate maximum electricity.
Prevent Permanent Lichen Etching
White lichen spores latch onto solar glass edges and frames. Their root structures can permanently etch anti-reflective coatings if left untreated.
Safety First — System Isolated
We always require panels to be isolated before commencing work, ensuring safe operations and total compliance with electrical safety standards.
Complete Photo Proof via CompanyCam
You do not need to be in. We take detailed before-and-after photographs so you can clearly inspect the transformation from the comfort of your day.
The Right Method for Every Solar Installation
We never take a one-size-fits-all approach. We start with the gentlest pure-water method and step up only when necessary.
Pure-Water Fed Pole System (1st Point of Call)
We wash your panels with 100% pure laboratory-grade deionised water through telescopic carbon-fibre poles. Dirt, dust and traffic films rinse away cleanly with zero mineral spots and no scratches.
Specialist Solar Cleaning Agent
For stubborn bird lime, chimney soot or baked-on grime that pure water alone won't lift, we apply an approved, non-abrasive solar cleaning agent formulated specifically for delicate photovoltaic glass.
Low-Pressure Steam for Lichen (Last Resort)
When solar panels are heavily overgrown with stubborn lichen spots, we deploy gentle, controlled low-pressure high-temperature steam to dissolve the lichen without mechanical abrasion.
Safe Access & Photo Verification
We reach panels safely from ground poles, tower scaffolding, or our in-house cherry picker. We provide complete before-and-after photo evidence via CompanyCam — and you don't even need to be home.
Tower Scaffolding & In-House Cherry Picker Access
Walking directly on fragile roof tiles or reaching across panels from dangerous positions risks tile breakages, damaged seals, and serious injury.
At Clearstone Solutions, we have our own in-house tower scaffolding and operated Multitel MZ250 cherry picker (MEWP). That means we can position ourselves safely above even the steepest, highest solar arrays without putting weight on your roof structure.
Operated Multitel MZ250 Cherry Picker
Reaches up to 25.1m with 14.35m outreach
Panels Must Be Isolated Before Work Commences
Electrical safety is our number one priority. Before our technicians begin washing panels, the solar system must be safely switched off / isolated at your inverter or main isolation switch. You don't need to be home for the clean itself — we will confirm isolation with you in advance.
What Our Customers Say
Watch what our customers have to say about Clearstone Solutions — real experiences from real homeowners.
The Right Cleaning Method for Every Surface
We choose the cleaning method to suit the surface — not the other way around. Three specialist techniques, each protecting your property while delivering lasting results.
Pressure Washing
High-pressure water cuts through thick grime and organic growth on hard surfaces like driveways and patios. Fast and effective — but it removes growth rather than killing it at the root.
Steam Cleaning
Low pressure, high heat. Steam cleans powerfully while protecting delicate surfaces like roofs — using a fraction of the water and killing growth at over 130°C.
SoftWashing
Low-pressure biocidal treatment that kills algae, lichen and fungi at the spore — keeping render and delicate surfaces cleaner for up to six times longer, with far less water and no surface erosion.
When something unexpected happened, we stayed until it was right.
“I had Shaun and his team clean the rendering on my house and clean my patio. The house clean was fine but there was a problem with the patio sealer reacting to the steam clean. Shaun took full ownership of the problem that was compounded by the remedial chemicals being affected by the excessive heat this summer. Shaun kept us fully informed and when the weather cooled, he returned and fully resolved all the issues leaving us with a fully restored beautiful limestone patio. An excellent company, one you can trust.”
