Pre-inspection
We inspect for cracked panels, loose clamps and damaged wiring visible from the roof. Anything of concern is photographed and flagged so you can raise it with your installer.
Outside
Clean panels, back to full output.
Dust, pollen, bird droppings and Melbourne pollen build-up can knock 10–25% off your solar system's output. We clean panels with pure water and soft-touch tools that keep coatings intact and warranties valid.
Overview
This isn't a job for a garden hose. Detergent residue and mineral spotting from tap water reduce output further and can damage panel coatings. We use the same pure-water system we use on high-end glass.

FAQs
What people ask before booking.
Something not covered? Send us a message and we'll answer honestly — even if the honest answer is "we're not the right fit."
Ask a questionAnnually for most Melbourne systems. Coastal properties, homes under trees, or systems with a low tilt (which don't self-rinse well) benefit from twice-yearly cleans.
No — pure-water soft-brush cleaning is the method recommended by most panel manufacturers. Pressure washing or abrasive cleaning is what voids warranties.
Typically 10–25% depending on how dirty the array was. Bird-dropping-heavy systems can see even more, as those spots create localised hotspots that damage cells over time.
No. Most of our clients leave a key or provide access instructions. We'll send an ETA the morning of your booking and photo confirmation once complete.
