How Much Does Solar Panel Cleaning Cost in Melbourne? (2026 Guide)

What it costs

Residential solar panel cleaning with Clearline starts at $300 for a standard single-storey system.

Most Melbourne homes running a typical 6.6kW array on an accessible single-storey roof land at or near that figure. Double-storey properties, steep pitches, larger arrays, and first-time cleans on panels that haven't been touched in years all move it up.

We publish a starting price rather than a range, because a range tells you very little — the bottom of it is a job almost nobody actually has, and the top is padding. What you get from us instead is a floor, and then a fixed price once we've looked at your system. No hourly rates, and no variation on the day.

Commercial and strata solar is quoted per site. Array sizes and access arrangements vary too much for a starting figure to be useful, so we look at the property first.

What moves the number

• Panel count and system size — The single biggest factor. A 5kW array and a 13kW array are not the same job.
• Storeys and roof pitch — Single-storey and walkable is straightforward. Double-storey or steep changes the access equipment and the time.
• How long since the last clean — Routine maintenance is quicker than lifting two years of baked-on soiling and bird fouling.
• Roof access — Side gates, level changes, and whether equipment can get to the right elevation at all.
• Array layout — Panels split across multiple roof faces take longer than one clean run.

The cost that actually matters more

Dust, pollen and bird fouling build up on panels gradually, and the efficiency loss is easy to miss because it happens slowly enough that your bill just creeps up rather than jumping. Melbourne's dusty summer stretch and high-pollen spring are the two periods that tend to do the most damage to output over a full billing cycle.

Put simply: a system running below its real output for months costs more in lost generation than a single professional clean does. That's the trade-off worth thinking about, not just the cleaning invoice on its own.

What's included in a proper clean

• Soft-wash using purified deionised water — no detergents, no chemical residue
• Removal of bird fouling, pollen and general dust buildup
• A visual check of panel framing and mounting hardware
• A physical damage check for cracking or delamination
• A wiring access point condition check
• Before-and-after photos as part of your Property Care Record

How often to clean

Most Melbourne homes do well on a 6–12 month cycle, depending on location and soiling rate — properties near main roads, under trees, or in higher bird-traffic areas tend to need the shorter end of that range. If you can't remember the last time your panels were cleaned, that's usually the clearest sign it's due.
