How Much Does Solar Panel Cleaning Cost in Queensland?
Pricing for solar panel cleaning across South-East Queensland is fairly consistent if you know what to look for. Here's what an honest quote actually looks like.
Solar panel cleaning isn't priced like a haircut — but it's not as variable as some quotes suggest, either. Here's the real breakdown for residential and commercial systems across Brisbane, Logan and the Gold Coast.
Residential pricing (most homes)
- 6.6kW system (typically 16–20 panels): $100–$180
- 10kW system (24–30 panels): $180–$280
- 13kW system (30–36 panels): $250–$350
- Two-storey home or steep tile roof: add 15–25%
- Heavy bird-dropping or salt build-up: add a one-off detail fee
Commercial pricing
Commercial cleans are quoted per panel because system sizes vary so much. Expect $4–$8 per panel depending on access, frequency and how dirty the array is. Recurring contracts (every 6 or 12 months) usually unlock the lower end of that range.
What affects the price
- Panel count — bigger arrays = more time, but better per-panel rate
- Roof access — single-storey colorbond is cheapest; steep two-storey tile is the most expensive
- Travel — within Brisbane/Logan/Gold Coast there's no callout fee from us
- Condition — moderate dust is included; heavy bird droppings are a small one-off detail charge
- Frequency — annual customers get a returning-client rate
Beware of the lowball quote
Quotes under $80 for any rooftop solar clean usually mean one of three things: no insurance, hose-from-the-ground (which doesn't actually clean), or a hidden upsell on the day. A proper deionised water clean takes 60–90 minutes for a typical home and uses purpose-built equipment — that has a real cost.
How fast does it pay back?
On a 6.6kW system that's lost 20% of its output to grime, recovering that output usually means an extra $80–$150 in saved or exported electricity per quarter. Most cleans pay for themselves on the next quarterly bill.
