Professional solar cleaning for the Beaches

Dirty panels quietly cost you money

Your solar system was a serious investment — but a thin film of salt, dust and bird mess can rob it of output every single day. On coastal Northern Beaches roofs, dirty panels can run well below their rated capacity, and rain won't fix it: salt residue isn't water-soluble, so it concentrates as rainwater dries.

We restore that lost efficiency with the right gear and a careful hand — same owner-operator every visit, on time, with a tidy job and no surprises.

The right equipment matters

Built to clean panels — not just glass

Solar panels aren't windows. The wrong tools scratch the surface, strip the protective coating or crack the seals — and that can void your warranty. So we treat every panel like the precision piece of kit it is.

  • Solar-safe scrapersFor baked-on grime, lichen and bird mess, we use non-abrasive, panel-rated scrapers that lift the build-up without ever marking the glass.
  • Purified waterUltra-pure, de-ionised water dissolves salt and dirt, then dries spotless — no minerals, no smears, no chemical run-off near your roof or garden.
  • Soft, panel-specific brushesGentle, soft-bristle brushes made for solar — they clear the surface fully while protecting the coating, cells and seals. Never a pressure washer.
  • A health check while we workAs we clean, we check for cracks, hot-spots, loose connections and damaged cells — so small problems get spotted before they get expensive.

Why it matters here

Salt air is brutal on coastal panels

The Northern Beaches is one of Sydney's sunniest spots — perfect for solar — but the same ocean air that brings the sunshine coats your panels in salt. Left alone, it doesn't just cut output; it etches into the glass. Here's what a regular professional clean protects:

Maximum energy & savings

Clean cells absorb more sunlight and make more power. For a typical Beaches system, a professional clean often pays for itself in recovered output within the first billing cycle.

Protect the panels & warranty

Salt left to sit etches the glass permanently. Regular purified-water cleaning lifts it before it bonds — extending your system's life and keeping the maintenance records many warranties require.

Catch problems early

Up on the roof, we inspect as we go — spotting cracks, hot-spots and loose connections that quietly drain performance, so they get fixed before they cost you.

Right on the water we usually suggest a clean every six months; set further back, an annual clean with a mid-year check is plenty. We'll recommend the right rhythm for your roof when we quote.

Good to know

Solar cleaning questions, answered

Doesn't the rain clean my panels?
It's the most common myth in solar. Rain rinses some loose dust, but it leaves mineral deposits behind as it dries — and coastal salt residue isn't water-soluble, so it actually concentrates on the surface. On the Northern Beaches, panels need a proper professional clean regardless of how much it rains.
What's the $59 drone inspection?
Before any cleaning, we fly a drone over your roof and check every panel up close — safely, with no one walking on your tiles. It's $59. If your panels don't need cleaning, you've had a full health check for peace of mind. If they do, we take the whole $59 off the price of your clean, so the inspection effectively costs you nothing.
Will cleaning void my warranty?
No — done correctly, it helps protect it. We use purified water, solar-safe scrapers and soft panel-specific brushes — the gentle, non-abrasive methods manufacturers recommend. Many warranties actually require evidence of regular professional cleaning.
How often should panels be cleaned here?
For homes on or near the water, every six months because of salt build-up. Set further back, once a year with a mid-year inspection is usually enough. We'll assess your roof and suggest the right schedule when we quote.
Do you use chemicals or a pressure washer?
Neither. Just ultra-pure, de-ionised water with soft brushes and panel-rated scrapers. No chemicals near your roof or garden, and never a pressure washer — that can crack the glass or strip the seals.
Can you reach panels on a two-storey roof?
Yes. We're set up to clean panels safely at height, with the right access and safety gear — far less disruptive than the alternatives, and safer for everyone.
How much does solar panel cleaning cost?
It depends on the number of panels, roof access and how much build-up there is. Use our instant online quote tool for a price in under a minute, or send your details and we'll confirm an exact, obligation-free figure.
