Dirty panels can lose 15–25% of their output. We clean them using a professional deionised water system — no streaks, no residue, no scratches. Fully insured, satisfaction guaranteed.
What dirty panels are costing you
Dust, pollen, bird droppings and grime build up quietly — and cost you money every day they're left on the glass.
A layer of grime can reduce solar output by 15–25%. A professional clean restores that lost generation and helps your system perform as designed — particularly important during Melbourne's high-sun months.
We use a professional DI water system. Unlike tap water, deionised water contains no minerals, so it leaves zero residue or streaking on the glass when it dries. The result is genuinely spotless panels.
We use soft brushes and low pressure — never abrasive tools or harsh chemicals. This protects the anti-reflective coating and the panel surface, keeping your manufacturer warranty intact.
Getting on a roof safely requires the right equipment and training. We handle it professionally so you don't have to — fully insured to $10M, with no risk to you or your property.
Before & after — Melbourne solar panels
These are real panels cleaned by Brophy's. The difference in surface clarity is immediate — and so is the difference in output.
Bird droppings, dust and organic buildup like this are common across Melbourne — especially in leafy suburbs and areas near parks. Our DI water system removes all of it without leaving a trace.
How we clean solar panels
Solar panels require a specific approach. The wrong method — too much pressure, abrasive brushes, or tap water with high mineral content — can cause permanent damage. Here's what we do instead.
We assess the roof pitch, panel layout and soiling type before starting — bird droppings, dust, lichen and general grime all require slightly different handling.
We use our deionised water system to rinse loose debris from the panels at low pressure before any brushing. This avoids grinding particles across the glass surface.
Using soft, panel-safe brushes fed by our DI water system, we work across the full surface of each panel — removing stubborn deposits without scratching or marking the glass.
A final DI water rinse removes any remaining residue. Because DI water contains no minerals, it dries spotlessly clean — no streaks, no water marks, no film.
Why deionised water makes the difference
Tap water contains dissolved minerals — calcium, magnesium, and others — that leave a visible film on glass as the water evaporates. This is the white residue you see on windows after rain. On solar panels, that residue blocks light and reduces output. Deionised water has had those minerals removed, so when it evaporates, it leaves absolutely nothing behind. It's the professional standard for any surface where optical clarity matters.
Panel types & soiling conditions
We clean all common residential and commercial solar panel systems across Melbourne, handling a full range of soiling types.

"Glad I found Eoin who did a brilliant job with pressure washing my algae covered outdoor tiles! The before and after photos speak for itself. Friendly, punctual and reliable."
"From the moment he arrived, he was professional, efficient, and clearly knew his stuff. He even pointed out a couple of small issues we wouldn't have noticed ourselves and took care of them on the spot. Reliable, friendly, and genuinely takes pride in his work."
