Starting at $150.
Davis's newer neighborhoods like Mace Ranch and North Davis Farms are more likely to fall under California's post-2020 solar requirement for new homes than the older housing near the Downtown Core and University Avenue, where panels would only be a retrofit if present at all.
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.
