Solar Panel Cleaning in Rancho Cordova, CA

Yes. Dust, pollen and bird mess form a film on the glass that blocks sunlight before it reaches the photovoltaic cells. Studies and our own customers' experience show a measurable output increase after cleaning — especially for panels that have not been cleaned in over a year.

The output gain depends on how dirty the panels were. Heavily soiled panels can see a significant improvement; lightly soiled panels see less. But the cost of cleaning is low relative to the energy it recovers.

Household detergents leave a film on panel glass that actually attracts more dust. Hard water from a garden hose leaves mineral spots that etch into the glass over time. We use deionised water, which has no minerals and leaves no residue, so the panels stay clean longer.

We also use a soft brush designed for solar glass — never abrasive pads or scrapers, which would permanently scratch the coating.

We clean both roof-mounted and ground-mounted arrays. Roof-mounted panels are usually accessed with extension poles and a harness system, and are often combined with a roof wash or gutter clean in the same visit.

Ground-mounted arrays are easier to access and can be cleaned quickly. If you have a large ground array, request a quote and Christian will price it.

Because roof-mounted solar panels require the same access setup as a roof wash, we usually clean them in the same visit. Combining the two keeps the cost down — you are paying for one site visit, not two.

If your roof needs cleaning too, book them together. If the panels just need a rinse and the roof is fine, we can do panels only.
