This one is priced after we see the job — tell us what you need and we will come back with a number.
Starting at $150.
Antelope's homes, built mostly since the 1980s, sit across a range of eras relative to California's 2020 solar mandate — newer sections built after 2020 are more likely to carry panels installed with the original build, while older 1980s-and-90s construction would only have them as a retrofit.
Hard water is the enemy of a solar panel wash, more than dirt is. Minerals left behind by hard water film over the glass and can hold onto grime just as much as they clean it off — so the water gets softened before it touches the panels, and the wash itself is brushes and water, not pressure or chemicals that could damage the coating.
Pricing starts at $150 for a visit — that's the minimum even if there are only a few panels on the roof. Past that, it's $10 per panel. A steep roof pitch or a hard-to-reach second story raises the minimum to $200, regardless of panel count — the complexity of the roof is part of what sets the price, not just the number of panels.
One thing we won't do: put a number on what a wash is worth to your electric bill. We don't measure output before and after a visit, so we don't know the actual gain for your roof — and neither does anyone quoting you a percentage from a marketing page. What we can tell you is what the wash removes: dust, pollen, and the mineral film that builds up between washes. What that's worth in kilowatts depends on your system, your roof, and your utility rate — none of which we can honestly guess.
One thing we always check while we're up there: the roof underneath and around the panels. Moss tends to build up specifically in that spot, because the panels block direct sun and the area stays damp longer — so the roof under panels is often in worse shape than the exposed parts of the same roof. We wash whatever we can reach, but not every spot under a panel is reachable, and we won't claim to reach the center of every one. Cleaning the roof itself, where it needs it, is its own job — priced by roof cleaning, not the panel wash, and the price depends on the roof's condition.
Antelope's mixed construction era means some panels are original to the build and some are retrofits, depending on when the specific home was built.
