Solar panels are newer to some Sacramento neighborhoods than others. Natomas's newer construction is more likely to have panels installed under California's building code requiring solar on new homes since 2020, while Land Park and East Sacramento's older bungalows would have them added later, if at all, often at a different roof angle than a home built with panels in mind from the start. The valley's dry summers, June through September, are when dust and pollen build up fastest on any panel in the city.
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.
Panels on Sacramento's newer construction were typically installed to code from the build; older-home installations are retrofits and vary more in angle and mounting.
