Ways to save
- Bundle the clean with a gutter clean, booking them together typically saves $50–$100 versus two separate call-outs, and on a small system that's the difference between the clean paying for itself and not.
- Insist on deionised or purified water and a soft brush, done early morning or late afternoon. Never let anyone use a high-pressure washer or clean in midday heat, thermal shock and seal damage can void the panel warranty.
How we estimate this
Cleaning a residential solar array in 2026 typically costs $150–$400, with the sweet spot around $180–$260 for a standard 6.6 kW system. Per panel, that's roughly $8–$12 at the budget end and $15–$20 in most metro areas (more in Sydney). The minimum call-out is about $200 for a single-storey roof and $300 for a two-storey one.

Understanding solar panel cleaning costs in Australia
Cleaning a residential solar array in 2026 typically costs $150–$400, with the sweet spot around $180–$260 for a standard 6.6 kW system. Per panel, that's roughly $8–$12 at the budget end and $15–$20 in most metro areas (more in Sydney). The minimum call-out is about $200 for a single-storey roof and $300 for a two-storey one.
The two-storey premium isn't about extra panels, it's height-safety compliance. A legitimate operator on a two-storey roof has to use harnessing and anchor points, so a suspiciously cheap two-storey quote usually means someone is cutting safety corners. Soiling type also matters: bird droppings, lichen, salt film, pollen and bushfire ash are all harder to shift than ordinary dust, and regional or rural jobs carry a 20–40% travel premium.
The economics are real but modest. Dirty panels lose somewhere around 5–20% of their output, so on a small system a clean can take a year or more to pay for itself, which is exactly why bundling it with a gutter clean makes the call-out worthwhile. The best return comes in dusty inland and agricultural areas, near the coast where salt builds up, under trees, and after a smoky bushfire stretch.
Frequently asked questions
How much does solar panel cleaning cost?
Typically $150–$400 in 2026, about $180–$260 for a standard 6.6 kW array, or roughly $8–$20 per panel. Minimum call-outs are around $200 single-storey and $300 two-storey.
Why is a two-storey clean more expensive?
It's the height-safety gear, not the panel count. A proper operator must use a harness and anchor points on a two-storey roof, so a very cheap two-storey quote usually means corners are being cut on safety.
How often should solar panels be cleaned?
Annually is enough for most homes, but more often near trees, dust, agricultural land or the coast, and after bushfire-ash periods. Always use purified water and a soft brush, never high pressure or midday heat.
