Vista Fox cleans residential and commercial solar panels across Adelaide with deionised water and soft brushes, without walking on the panels. Typical prices are $150–$220 for a small 3–5 kW array, $180–$280 for a 6–7 kW array and $280–$450 for 10 kW+ systems or double-storey roofs. Book online and we'll confirm your price.
If your solar generation has dropped noticeably compared with the same time last year and the inverter isn’t showing a fault, dirty panels are a likely cause. Adelaide’s dry, dusty summers, plus pollen, birds and bushfire-season smoke and ash, all leave a film on panels over time. Vista Fox cleans residential and commercial solar arrays with pure deionised water and soft-bristle telescopic gear — no abrasive scrub, no detergent residue, no rooftop work for you.

Prices sit lower in the band when solar is booked with window cleaning or gutters on the same visit, and higher for a first clean on an array that hasn’t been touched for years. Send your system size through the online booking form and we confirm the price before you commit.
Why dirty panels cost you money
A grimy solar panel can’t convert as much sunlight as a clean one. How much output is lost depends on the panel tilt, local dust, bird activity, and how long it’s been since the last clean — low-tilt arrays in dusty areas and under trees tend to suffer most.
Lost generation means less power for your home and less to export. For a worked example of the payback maths, see our guide to solar panel cleaning ROI in Adelaide.
When solar panel cleaning makes sense
- You can see visible bird, dust, or pollen build-up from the ground or via the inverter app’s panel-level view
- System output is trending down — many inverter apps show year-on-year comparisons; a noticeable drop with no fault is a common sign of soiling
- Pre-summer service — a clean before the long summer days lets the panels make the most of peak generation
- After smoke or ash — ash and smoke residue are best removed sooner rather than later
- Coastal homes — Glenelg, Henley, Brighton, Seacliff: salt spray builds up on panel glass and is harder to remove the longer it sits
- Large commercial arrays — warehouse and industrial rooftops
- You haven’t cleaned the panels since they were installed — many arrays go years between cleans
Our solar panel cleaning method
Solar panels are not house windows. They have a tempered, often anti-reflective coated glass surface, and aggressive cleaning can scratch or damage that coating. We use a gentle method in line with common manufacturer guidance — check your panel manufacturer’s cleaning instructions if you’re unsure.
- Pure deionised water only — no detergents, no abrasives, no high-pressure jet-wash. Detergent can leave a residue that attracts dirt; high pressure can damage seals and frames.
- Soft-bristle, telescopic carbon-fibre pole — same kit as our window crew, scaled for panel work. Most residential arrays are cleaned from the gutter line; we don’t walk on panels.
- Early morning or late afternoon — not on a hot panel. Cold water on very hot glass risks thermal shock.
- Inverter check before and after — a pre-clean and post-clean reading noted for you. Weather affects the numbers, so your own data over the following week is the best comparison.
- No standing on panels. We work from gutter line or ladder, not on the array.
Process
- Book online or get a site quote. Residential — send your details through the book-online form and we’ll come back with a price and a date. Commercial — a site walk and a contract quote.
- Schedule for cool conditions. We work pre-9am or post-4pm in summer; we don’t clean panels in midday peak heat.
- Clean. Deionised water-fed pole and soft brush. A typical residential array doesn’t take long; larger systems take longer.
- Output check. Inverter pre/post reading and photos of the panels.
- Pay and re-book. Many residential customers add solar to a recurring window-cleaning visit — annual is a sensible baseline; twice-yearly for dusty or coastal homes.
Solar panel cleaning cost in Adelaide
Pricing depends on system size, roof access, and tilt:
- Residential — small array (3-5kW, single-storey, easy access): $150-$220
- Residential — standard array (6-7kW, single-storey, standard access): $180-$280
- Residential — large array (10kW+, double-storey or steep pitch): $280-$450
- Commercial array (rooftop systems above 30kW): site-quoted; typically $1.50-$4 per panel depending on access and frequency
What pushes price within the range:
- Roof pitch and access — steep pitches and limited gutter-line standoff add ladder time
- Bundled with window or gutter cleaning — a combined price applies when the truck’s already on site (for example, solar with gutter cleaning)
- Recurring schedule — ask about recurring pricing
- First clean of a long-neglected array — heavy bird-staining or years of build-up needs a longer first pass; subsequent maintenance cleans drop in price
We don’t do “from $99” pricing — that’s a callout fee, not a clean.
Solar panel cleaning in the Adelaide Hills and outer suburbs
A lot of searches for solar panel cleaning near me come from the Hills and the outer fringe, where the panels work hardest and get dirtiest. We service Stirling, Aldgate, Crafers, Bridgewater, Mount Barker and Hahndorf on our regular routes, along with Gawler, the northern growth suburbs and the southern coast.
Hills arrays have their own problems. Eucalypt oil and leaf litter leave a sticky film that rain doesn’t shift, pollen loads are heavy in spring, and smoke or ash from the fire season settles on the glass. Many Hills roofs are also steeper and higher than a metro single-storey, so we plan access from the gutter line with the telescopic pole and never by walking the array. If gutters are full of leaves at the same time — common under gum trees — a gutter clean on the same visit stops the debris washing back over the bottom row of panels.
Getting the most out of the clean
A few simple habits make each clean last longer and help you see the result:
- Check your inverter app before and after. Compare a sunny day before the clean with a similar sunny day after. We record a reading on the day, but your own data over a week is the best measure.
- Time it before summer. A clean in October or November sets the panels up for the long, high-generation days when soiling costs you the most.
- Watch the bottom edge. Dirt collects where water beads along the lower frame. If you can see a brown line forming there from the ground, the panels are due.
- Keep birds off. If pigeons are nesting under the array, bird-proofing mesh is worth considering — droppings are the hardest soiling to remove and cause hot spots.

FAQs
Q: Do you clean solar panels in Stirling and the Adelaide Hills? A: Yes. Stirling, Aldgate, Crafers, Bridgewater, Mount Barker and Hahndorf are on our regular routes. Hills arrays often need cleaning more often because of eucalypt oil, pollen and fire-season ash, and we clean them from the gutter line without walking on the panels.
Q: How much does it cost to clean solar panels in Adelaide? A: Residential systems run $150-$450 depending on array size and roof access. A standard 6.6kW single-storey home is normally $180-$280. Commercial arrays are priced per panel ($1.50-$4 typically) on a site quote. Bundle with window cleaning or gutter cleaning and the combined price drops.
Q: How often should solar panels be cleaned in Adelaide? A: Once a year is the maintenance baseline for most metro homes. Coastal and dusty areas benefit from twice-yearly. Bushfire-affected seasons may add a one-off — ash isn’t something to leave on panel glass.
Q: Will cleaning the panels actually improve generation? A: On visibly dirty panels, usually yes — how much depends on how dirty they were, the tilt and the weather. We take a pre and post inverter reading on every job, and your own app data over the following week is the best measure.
Q: Won’t rain wash my panels for me? A: Rain rinses the loose dust off the upper portion of panels. It doesn’t shift bird droppings, pollen residue, salt spray, or the bonded grime that sits on the lower edge of every panel where water beads and dries. Rain is a partial solution; a proper clean is the complete one.
Q: Do you walk on the panels? A: No. Walking on panels can cause micro-cracks and may affect the manufacturer’s warranty. We work from gutter line and ladder using a telescopic water-fed pole.
Q: Why deionised water and not detergent? A: Detergent can leave a film that attracts dirt again quickly. Pure deionised water leaves no mineral residue and dries clear. Check your panel manufacturer’s cleaning guidance — many recommend water and a soft brush.
Q: Is it safe to clean panels in summer? A: Yes — but only in cool morning or late afternoon windows when the panel surface temperature is moderate. Cold water on very hot panel glass risks thermal shock. We schedule summer jobs around that.
