Dirty panels are losing you money.
Right now.
Professional soft-wash panel cleaning restores up to 10% of lost annual output. Takes half a day. Pays for itself fast. Works on all panel types — including Aiko.
A dirty panel isn’t just unsightly. It’s a bill you’re paying every month.
Up to 10%
Annual output restored after a professional clean — enough to make the clean pay for itself within months
Half a day
Typical completion time for a residential clean — most jobs are done before lunch with no disruption to you
All types
Our soft-wash process works on all panel types, including n-type TOPCon Aiko panels — no aggressive chemicals, ever
Four things building up on your panels right now.
Bird droppings
The most damaging soiling type. Even a small patch blocks cells and can cause hotspots, reducing output from an entire string — not just the soiled panels.
Moss and lichen
Moss grows in the lower corners of panels and spreads upward over time. It holds moisture and can cause microcracks in panel cells if left untreated.
Dust and pollution
Urban and roadside properties accumulate a fine film of dust and airborne particulates. It’s invisible at a glance but creates consistent output loss across every panel.
Pollen and organic debris
Spring and summer pollen deposits build up on panel surfaces and trap moisture. In rural areas near trees and crops, this can be a significant seasonal output reducer.
Done right. Every time.
Soft-wash only — never high pressure. Deionised water only — no detergents, no residue, no risk to panel warranties.
Initial inspection
We check panel condition, identify any physical damage, note heavy soiling areas and take a before reading from your inverter app.
Soft wash
Panels are cleaned using purified deionised water and soft brushes — the same method recommended by Aiko, Solax and all major manufacturers.
Rinse and dry
Deionised water leaves no mineral deposits or streaks on drying. No detergents means no residue to attract future soiling faster than before.
Before/after comparison
We take an after reading from your inverter and provide a written before/after output comparison so you can see exactly what was restored.
More than a wash. A proper visit.
Deionised water clean
Pure water soft wash — no detergents, no streaks, no residue, no warranty risk.
Roof inspection
Visual check of the roof area visible during the clean — we flag anything that warrants attention.
Bird guard check
We check your bird protection mesh or spikes for damage or gaps while we’re up there at no extra charge.
Before/after output reading
Inverter output logged before and after the clean so you have a documented record of performance improvement.
Written report
A brief written summary of what we found, what we cleaned and any recommendations — sent same day.
Surge protection check
We verify your surge protection device is present and intact — a quick check that takes seconds and matters.
Add-on quote if issues found
If we find anything that needs attention — bird damage, loose mounting — we quote for it separately with no obligation.
Discount for plan members
MiniGrid MegaCare maintenance plan members receive a discount on every panel clean. Ask us about plans.
We’re already on your roof. Make the most of it.
Add-on services can be booked alongside your panel clean — saving you a separate visit and often a call-out fee.
Bird Guard install
Mesh skirting around your panels to stop birds nesting underneath — the most common cause of wiring damage.
Surge protection
If your system was installed without surge protection, we can fit it during your clean visit.
Solar MOT
A full system health check and certificate. Pairs perfectly with a clean — see output before and after with a full picture of system health.
Battery survey
If you’re thinking about adding battery storage, our engineers can assess your system compatibility during the clean visit.
The output speaks for itself.
These are indicative comparisons based on typical residential systems. Actual output restoration depends on soiling level, panel type and weather conditions at time of clean. All figures from MiniGrid clean records.
Lightly soiled system
Moderately soiled
Heavily soiled (bird activity)
If you have solar panels, the answer is probably you.
Anyone who hasn’t had one
If you’ve never had a professional clean, there’s almost certainly output to recover. Even newer systems benefit from a baseline clean.
Rural properties
More birds, more trees, more pollen. Rural roofs typically accumulate soiling faster than urban ones — annual cleaning is recommended.
Older systems (3+ years)
Systems over three years old have typically had at least one season of heavy soiling. The older the system, the more likely cleaning restores measurable output.
Visible soiling
If you can see droppings, green patches or discolouration from the ground, the impact on output is almost certainly significant.

Dirty panels are costing you.
A clean is cheaper than the loss.
Most panel cleans pay for themselves within a few months in restored output alone. There’s no good reason to wait.
