Solar Panel Cleaning in
What's included
What's included in a Dunzo solar panel cleaning?
No pressure washers, no abrasive pads. Here's what actually happens on your roof.
Soft-wash, deionized rinse
Low-pressure washing with deionized water so panels dry spot-free: no mineral streaking, no abrasive pads.
Panel-safe tools only
Soft brushes and squeegees rated for solar glass: nothing that can scratch the coating or void your warranty.
Visual inspection included
Every panel checked for cracks, loose mounts, or debris while we're already up there.
Photo report
A written, photographed condition report so you know exactly what shape your system is in.
Losing output to dust?
How do you know your solar panels need cleaning?
Any one of these is worth a free inspection, especially heading into Sacramento's sunniest months.
- Visible dust, pollen, or bird droppings on the panels
- It's been over a year since your last cleaning
- Months of dry weather with no rain to rinse the panels
- Panels sit under or near trees with sap or leaf debris
- Your energy production seems lower than past summers
- Streaking or spotting left behind after a light rain
Real technicians, real work
Why don't we pressure wash solar panels?
Solar glass scratches easier than you'd think, and high pressure can crack seals around the frame. We work each panel by hand with tools built for solar, so the coating stays intact and the warranty stays valid.
- Deionized water for a spot-free, streak-free finish
- Soft brushes only: nothing that can scratch the glass
- Same crew handles the clean and the photo report
Why it matters
Does dust really cut into solar panel output?
Up to 25%
energy output can be lost from heavy dust and grime buildup on uncleaned panels.

Sacramento's dry season, by the numbers
From May through September, Sacramento sees almost no rainfall, meaning panels go months without a natural rinse while dust and pollen keep building up.

Solar panel cleaning questions.
The things Sacramento homeowners ask us most, answered plainly.
Rather talk?
(916) 571-664401How much does solar panel cleaning cost in Sacramento?
A professional cleaning for a residential system typically runs $150–$350, depending on the number of panels and how they're mounted. We give you a firm price after a free inspection, before any work starts.
02How often should solar panels be cleaned?
Most Sacramento-area homes do well with one to two cleanings a year. Homes near trees, in high-pollen areas, or with heavy bird activity often need more frequent cleaning to keep panels performing at their best.
03Does cleaning actually improve energy output?
Yes. Dust, pollen, and grime block sunlight from reaching the cells, and that buildup only gets worse the longer it sits, especially through Sacramento's long dry season when there's no rain to rinse panels naturally.
04Will cleaning void my solar panel warranty?
Not with the right method. We use a soft-wash approach with deionized water and panel-safe tools: no pressure washers, no abrasive pads, and nothing that would void a manufacturer's warranty.
05Do you use pressure washers?
No. High pressure can crack seals and damage the anti-reflective coating on solar glass. We soft-wash with deionized water and soft brushes designed specifically for solar panels.
06Do I need to be home during cleaning?
No. As long as we can access the roof and any gated areas, you don't need to be present. We'll send your photo report by email when the job's done.
