Dirty panels cost you money. We restore your system's output using a deionised water fed pole system — no chemicals, no residue, cleaner for longer.
Get Your QuoteGrime on your panels is silently costing you money every day.
Dust, pollen, bird droppings and leaf debris build up on panels and block sunlight from reaching the cells. Research shows soiled panels can lose 15–25% of their output. That's electricity your system is failing to capture — and money you're not getting back.
Solar systems are a significant investment. Bird droppings in particular are acidic and can permanently etch the glass surface if left too long. Regular cleaning prevents this degradation and keeps your panels performing closer to their rated capacity for longer.
We use a deionised water fed pole system — pure water with no dissolved minerals. Unlike tap water, it leaves no residue or spots when it dries. This also means rain water doesn't pick up mineral deposits from the glass surface, so your panels stay cleaner between cleans.
Whether you're feeding back to the grid or running your home on solar, maximum output means maximum return. A professional clean is one of the cheapest ways to improve the financial performance of your solar system and make sure it's actually earning its keep.
A professional clean that restores output and keeps panels cleaner for longer.
Every panel individually scrubbed with a soft brush and rinsed thoroughly. Bird droppings, lichen, dust and pollen removed without scratching the glass or risking your panel warranty.
Our water filtration system removes all dissolved minerals before the water touches your panels. The result is a spot-free, streak-free finish — and because there's no mineral residue on the glass, rain water doesn't dirty the panels as quickly afterwards.
No harsh chemicals, no abrasive tools. Our pure water cleaning method is safe and effective across all panel types and brands — monocrystalline, polycrystalline and thin-film — and won't void your manufacturer warranty.
Already up on the roof? We can also clean your gutters and skylights while we're there.
We recommend getting your solar panels cleaned at least once a year, but every 6 months is ideal for the best energy return on your investment. In Melbourne's eastern suburbs, panels accumulate dust, pollen, bird droppings and leaf debris throughout the year — particularly in leafy suburbs like Kew, Balwyn, Templestowe and Doncaster where tree coverage is heavy. Dirty panels can lose 15–25% of their output, so a twice-yearly clean in autumn and spring keeps your system running at close to its rated capacity all year round. If you have a monitoring system, compare your output before and after a clean — the difference is often significant.
Solar panel cleaning costs vary depending on how many panels you have, how dirty they are, and how accessible your roof is. A small 6-panel system on a single-storey home is priced differently to a large 20-panel system on a steep double-storey roof with limited ladder access. We don't charge a flat rate because every property is different — instead we assess your system and provide a tailored quote.
