Dust, pollen, salt air and bird droppings cut solar output by 15–25% in Perth conditions. We clean using purified deionised water — no chemicals, no abrasives, no pressure washers on glass. Panels cleaner for longer, warranty intact.
Long dry summers mean panels go months without a natural rain rinse. Combine that with Perth's specific soiling sources and you have a significant output problem most owners don't see until they check their inverter data.
Perth's prevailing easterlies carry fine red dust from inland WA. Spring pollen from gums, paperbarks and suburban plantings adds a sticky film that bonds to the dust layer and won't shift in light rain.
Highly acidic and opaque. Even a small number of dropping-covered cells can cause a disproportionate output drop through shading and potential hotspot damage. Perth's Indian myna and pigeon populations make rooftop panels a constant target.
From Cottesloe to Rockingham and up through Joondalup, salt-laden sea air deposits a fine crystalline film on panel glass. It's invisible until you run your finger across the surface — and it cuts light transmission significantly.
Perth averages less than 10mm of rain between November and March. That's five months of accumulation with no natural cleaning. By the time Perth's first winter rains arrive in May, the soiling layer is baked on and rain alone won't shift it.
Homes under or near gum trees, jacarandas or paperbarks deal with sticky sap and bark deposits that ordinary water won't dissolve. These leave permanent-looking stains if left too long.
A sustained drop in generation that doesn't track with cloud cover or shade is almost always soiling-related. If your system is generating 20% less than this time last year, a clean is the first thing to try — and usually the fix.
The ProFlo solar cleaning method is built around one principle: leave the panels in better condition than we found them — not just visually clean, but chemically clean. Tap water contains dissolved minerals that leave white residue when they dry. We use deionised (purified) water that leaves nothing behind.
We dry-brush loose debris and bird droppings before wetting — wetting baked-on droppings first can spread them across the panel surface.
Deionised water fed through our on-truck purification system is applied with soft brushes. Zero TDS means zero mineral residue when it dries.
Panel frames and edges collect debris that washes back across the glass. We clean the full panel including frame channels and mounting points.
We photograph before and after, and flag any visible damage — cracked glass, delamination or discolouration — in the report.
One booking, one access setup, one invoice. Combining services costs less than two separate visits and saves you the coordination.
Full system cleaned with purified water and soft brushes. Before-and-after photos. Visible damage check included.

“Very happy with the outcome of my Solar Panel servicing. Quote was fair and they don't leave you feeling like they won't speak up if something is noticed. Top quality service — will return in future.”
“Was on time and done a fantastic job considering the amount of leaves that were there. Also got 99% of leaves from under the solar panels. Will definitely be getting it done again.”
“Thank you guys, most efficient — showed before and after pics of gutters and video of cleaning solar panels.”
Most residential systems in Perth cost between competitive pricing and $280 to clean, depending on system size, storey height and access. We give a firm price upfront — call 0460 290 926 or request a quote online.
Once or twice a year for most Perth homes. Coastal suburbs dealing with salt air, and homes under trees with heavy pollen or bird activity, benefit from more frequent cleaning. If your inverter output has dropped without a weather explanation, dirty panels are the likely cause.
We use purified (deionised) water and soft brushes — no harsh chemicals, no abrasive materials, no pressure washers on panel surfaces. Deionised water leaves no mineral residue when it dries, so panels stay cleaner longer. This method is in line with manufacturer guidelines and won't void your warranty.
No — provided it's done correctly. Most warranties actually require periodic cleaning to remain valid. Our method (purified water, soft brushes) meets manufacturer cleaning guidelines. Abrasive materials or pressure washers directly on glass would be the risk, and we don't use either.
Yes, and most clients find this the most efficient approach — one booking, one access setup, both jobs done. Ask about our combined gutter clean and solar panel clean package when you call.
Research consistently shows losses of 15–25% in typical Australian conditions after 12 months without cleaning. Panels with heavy bird dropping coverage can lose significantly more in the affected cells. A clean typically recovers most of that loss immediately — which often means the clean pays for itself in recovered generation within a few billing cycles.
Safety, environment and quality — independently audited to ISO standards. You're covered.
Pricing depends on system size, storey height and access. Combining a solar clean with a gutter clean in the same visit reduces the overall cost compared to two separate bookings. We provide a firm price upfront — call 0460 290 926 or request a quote online.
Research consistently shows losses of 15–25% in typical Australian conditions after 12 months without cleaning. Perth's long dry summers — where panels can go from November to April without significant rain — mean soiling accumulates without any natural rinse. Panels near the coast (Cottesloe, Fremantle, Rockingham) also deal with salt film. In a typical 6.6kW Perth system, a 20% output loss represents roughly 2.5–3kWh per day — at current feed-in and usage rates, a clean often pays for itself within a single billing cycle.
Once or twice a year for most Perth homes. Coastal suburbs (Cottesloe, Fremantle, Scarborough, Rockingham) dealing with salt air benefit from twice yearly. Homes under heavy tree canopy — particularly gums, jacarandas and paperbarks common across Applecross, Kalamunda and the Swan Valley corridor — may need more frequent cleaning. If your inverter output has dropped without a weather explanation, dirty panels are the likely cause.
We use purified (deionised) water — water that has had all dissolved minerals removed — applied with soft bristle brushes. No chemicals, no detergents, no pressure washers on panel glass. Deionised water leaves no mineral residue when it dries, which means panels stay cleaner longer than after a tap water clean. Our method aligns with manufacturer cleaning guidelines and will not void panel warranties.
No — provided it is done correctly. Most panel warranties actually require periodic cleaning to remain valid. Our method (purified water, soft brushes, no abrasives, no chemicals) meets manufacturer cleaning guidelines. Using a pressure washer directly on panel glass or abrasive materials are the risks to warranties — and we use neither.
Yes, and we recommend it. One booking, one access setup, one visit — both jobs completed and one invoice issued. It's the most cost-efficient approach and the most popular option for our Perth clients. Ask about combined pricing when you call.
Homes built before 1990 may contain asbestos-containing materials (ACM) — including asbestos cement gutters, fibro sheeting adjacent to gutters, or asbestos roof sheeting. ProFlo WA does not carry out any work on or near confirmed or suspected asbestos materials. Asbestos work requires a licensed asbestos removalist and is outside the scope of our services.
What this means for your booking: If your property was built before 1990, please let us know at the time of enquiry. Our crew will carry out a visual assessment on arrival. If asbestos-containing materials are identified or reasonably suspected — including cement gutters with a fibrous appearance, fibro fascia boards, or corrugated asbestos roof sheeting — we will not proceed with the job and no charge will apply.
Hard no: Confirmed loose-fill or friable asbestos on any part of the property is an automatic job decline. We will not work on these properties under any circumstances.
If you're unsure whether your property contains asbestos, the WA Department of Mines, Industry Regulation and Safety (DMIRS) has guidance on identification and licensed removalists in your area.
Most Perth jobs booked within the week. Combine with a gutter clean and save on access costs.
