Your Melbourne panels are leaking kWh. We get them back.

No — it's the opposite risk you need to watch. Manufacturers like Trina, Jinko, REC and LG generally require no soap, no abrasive brushes and no high-pressure water on the glass. We use pure water and a soft carbon-fibre brush specifically because it meets those warranty conditions. Ask your provider what they use before you book.

Only if there's no other safe option, and never on the panels themselves. We use water-fed poles from the ground or gutter line for most jobs, which avoids foot traffic on the glass entirely. Walking on panels is one of the leading causes of microcracks — no visible damage, but real drops in output over the following year.

Typically a 10 to 25% output recovery depending on how dirty the panels were and how long it's been. Bird droppings cause the biggest single-panel losses because they create shaded hot spots. We'll check your inverter or monitoring app before and after so you can see the difference.

Once a year for most homes. Twice a year if you're near the coast, under trees, near a busy road or flight path, or on a low-pitch roof that doesn't get a good self-rinse from rain. Commercial and rural systems usually need a 6-monthly schedule.

A visual check of the glass for cracks, the frames and racking for corrosion or looseness, junction boxes for water ingress, and a look at your monitoring app or inverter display for any string that's underperforming. Included with every clean at no extra charge.

Yes — we carry full public liability insurance for any job requiring roof access. Happy to send a certificate of currency before the job if you'd like to see it.

No. We use deionised, pure water only, run through an on-truck filtration system. It dries without spots or streaks and won't leave a residue that attracts more dust — and it keeps your panel warranty intact.
