Don't Let Dirty Panels Cost You Money
Most solar panel warranties require regular maintenance to stay valid — and most homeowners don’t realise their panels are underperforming until they check their power bill. A clean every 6–12 months keeps your system generating at full capacity and your warranty intact.
Chemical-Free, Warranty-Safe Cleaning
We never use detergents or pressure washers on solar panels. Our purified water fed brush system is the industry-standard method recommended by most panel manufacturers — gentle enough to protect your investment, effective enough to lift stubborn buildup.
Our Solar Panel Cleaning Process
1. Assessment
We inspect your panels for buildup, damage, and access requirements before starting.
2. Dry debris removal
Loose dust, leaves, and debris are removed first to avoid scratching during the wash.
3. Pure water scrub
Panels are cleaned with a soft brush and purified water, lifting grime without chemicals or high pressure.
4. Rinse & spot check
A final rinse removes all residue. We check each panel before packing up.
5. Optional roof inspection
While we're up there, we can flag any visible roof issues at no extra charge.
Reliable, Safe, and Efficiency-Restoring.
Solar panels are a significant investment — they deserve to be treated that way. At Mr Clean Exterior Washing, we use the correct method for the job, show up on time, and leave your site tidy. No shortcuts, no risk to your panels or warranty.
Protect Your Solar Investment
Solar panels are built to last 25+ years, but their output depends on how well they’re maintained. Regular cleaning is the single easiest way to protect your ROI and keep your system generating what it was designed to. Most Hamilton homeowners see a noticeable improvement in output after their first professional clean.
