Why solar panel cleaning is worth doing properly

The right method for solar panel cleaning

We choose the technique to suit the surface — soft washing or chemical-free steam where pressure would do harm, controlled pressure washing where it won't. That's how solar panel cleaning gets a lasting result without damage.

Stops damage before it costs you

Left to spread, moss, algae and lichen trap moisture against your roof, walls and surfaces and shorten their life. Regular cleaning is the cheaper, greener way to stay ahead of remedial building work.

Certified biocide treatments

Fully certified to disinfect and prevent regrowth, applied with minimal impact on occupants, pets and wildlife.

A friendly, local team

Owner-led and fully insured, known across Chichester and West Sussex for careful work and fair pricing — domestic and commercial equally welcome.

Why coastal salt and sand cut your panel output

Solar panels only work as well as the light that reaches the cells — and here on the West Sussex coast there is a lot working against them. Sea salt carried on the wind, fine sand blown off the beaches around West Wittering and Bracklesham, dust, pollen and bird mess all settle on the glass and build into a dull film. That film scatters and blocks the sunlight before it ever reaches the cells beneath.

The difference is that coastal panels soil far faster than inland ones. The salty, sandy air around Selsey, the Witterings and Bognor Regis means a noticeable layer can re-form within months — and rain alone does not clear it. Salt in particular dries into a stubborn haze that needs a proper clean to remove.

The performance and savings angle

Because the drop happens slowly, most people never notice their panels are underperforming — the generation figures just quietly slide. A coated array can lose several percent of its output, and a heavily soiled coastal one considerably more. Over a year, on a system you have invested thousands in, that lost generation adds up to real money.

A residue-free clean restores the glass to full clarity so the panels work as they were designed to. It is one of the most cost-effective things you can do for a solar system: a modest clean to protect the return on a large investment, and to keep your feed-in or export figures where they should be.

Our safe pure-water method

Solar glass, its seals and the anti-reflective coating are easily damaged, so this is no place for high pressure or harsh chemicals — both can scratch or etch the surface and even void the manufacturer warranty. Instead we use a gentle, residue-free pure-water system:

  • Purified, de-ionised water and a soft brush on a reach pole lift the salt, sand and grime without touching the panel with anything abrasive.
  • Because the water is purified, it dries completely spot-free — no chemical residue, no smears, nothing left on the glass to attract more dirt.
  • Reach-and-wash poles let us clean most arrays safely from the ground, with no need to walk on the roof or the panels.

It is the same careful, surface-appropriate thinking we bring to all our work, from roof cleaning to soft washing: the right method for the material, never one tool for everything.

Domestic and commercial arrays

We clean everything from a handful of domestic panels on a Chichester rooftop to larger commercial, agricultural and ground-mounted arrays across West Sussex. For homeowners it keeps the system you paid for performing at its best; for businesses and farms with bigger installations it protects a serious asset, and we have the reach equipment and full insurance to clean them safely. On larger sites we are always happy to come out for a no-obligation look first.

FAQs

Common questions about solar panel cleaning

Do you clean solar panels in Chichester and the coastal villages?
Yes. Solar panel cleaning is one of our specialist services across Chichester (PO19) and the harbour villages — West Wittering, East Wittering, Bracklesham, Birdham, Itchenor and Selsey (PO20) — out to Bognor Regis (PO21/PO22) and Emsworth (PO10). The closer you are to the coast, the more the salt and sand build up, so it is well worth a regular clean.
Why do coastal solar panels near the Witterings get dirty so quickly?
On the exposed coast around West Wittering, Bracklesham and Selsey, panels are constantly coated with wind-blown sand, sea salt and dust. That film sits on the glass, scatters the light before it reaches the cells and quietly cuts how much electricity the array generates — far faster than panels further inland.
Will dirty panels really reduce how much electricity I generate?
Yes. A layer of salt, sand, dust, pollen or bird mess shades the cells and can noticeably lower output — often by several percent, and more on a heavily soiled coastal array. Because the loss creeps up gradually you rarely notice it day to day; a residue-free clean restores the panels to full performance.
Is it safe to pressure wash solar panels?
No — high pressure and harsh chemicals can damage the glass, the seals and the anti-reflective coating, and can void the manufacturer warranty. We use a gentle, residue-free pure-water method: purified water and a soft brush on a reach pole that lifts the dirt and dries spot-free, with no scratching and no chemical residue left behind on the glass.
Do you clean commercial solar arrays as well as domestic roofs in West Sussex?
We do both. From a few domestic panels on a Chichester rooftop to larger commercial and agricultural arrays across West Sussex, we have the reach-and-wash equipment and the insurance to clean them safely. For bigger sites we will happily come out for a no-obligation look first.
