Or Call Us NowWashPro SFV provides professional solar panel cleaning for homes across Los Angeles County and Ventura County. You paid serious money to put power production on your roof. Dirty glass quietly takes a cut of it every single day, and Southern California weather never washes that film away on its own. Our job is simple: get every panel back to producing what it was engineered to produce, without touching the glass with anything that could harm it.
Every solar cleaning visit covers the whole array, not just a quick rinse:
We clean rooftop arrays, ground mounts and carport systems, and we offer bird proofing mesh as an add-on for arrays that pigeons have claimed as home. Many homeowners pair the visit with window cleaning, since the purified water system is already on site.
Southern California is one of the best places in America to own solar and one of the worst places to keep it clean. The reason is the same in both cases: it almost never rains. Dust, pollen and smog settle on your panels through a dry season that runs most of the year. The marine layer dampens the glass overnight, the grime sticks, and the afternoon sun bakes it into a haze. Layer by layer, your array dims.
Industry soiling studies commonly put production losses at 15 to 25 percent in dusty, low-rain climates like ours. That is not a worst case. That is the everyday tax on an array that has gone a year or two without a proper wash. On a system sized to cover your electric bill, losing that slice of output means buying back power from the grid at full price. We walk through the evidence in our guide on whether cleaning solar panels increases output, and the short version is yes, measurably.
Bird droppings are the worst offender of all. Dust dims a panel evenly, but a dropping blacks out cells completely. The shaded cell resists current instead of producing it, heats up, and becomes a hot spot that can permanently degrade that section of the panel. A handful of droppings can drag down a whole string. If pigeons have moved in under your array, the problem compounds weekly, which is exactly why we offer bird proofing along with the cleaning.
Solar glass is not ordinary glass. Most panels carry an anti-reflective coating engineered to pull more light into the cells, and that coating is the first casualty of careless cleaning. So our rule is strict: deionized water and soft brushes only. No detergents, no abrasives, no pressure washing, ever. That discipline protects the coating, and it keeps you on the right side of your panel manufacturer's warranty, which expects gentle, chemical-free care.
Deionized water is the heart of the method. Stripped of its minerals, it pulls dirt off the glass aggressively and dries without a single spot, no squeegee and no soap required. Tap water would do the opposite. SFV, LA and Ventura tap water is hard, and letting it dry on solar glass trades a dust film for a mineral one. Soft brush heads do the agitation, floating grime loose so the rinse can carry it off the low edge of the array.
Timing matters as much as tools. We clean panels cool, in the early morning, before the sun turns the glass into a griddle. Cold water on hot tempered glass stresses it, and water flashing off a hot panel leaves residue behind no matter how clean your technique is. An early slot means a safer wash and a spot-free dry, and your array is back at full strength for the best production hours of the day.
Bird droppings get their own protocol. We soak each spot with deionized water until it releases, then lift it with the soft brush. Dry scraping grinds grit across the coating, so we never do it. Where birds keep coming back, we can install bird proofing mesh around the perimeter of the array, closing off the warm, sheltered gap underneath that pigeons love. And because our crews work on tile and shingle every day, your roof gets the same careful footwork we bring to roof cleaning, with walk paths planned before anyone steps up there.
Most residential solar cleanings in LA and Ventura County land somewhere between $150 and $350 per visit, with the price per panel dropping as the array gets bigger. Bundling with another service or setting a recurring schedule brings it down further. Your exact quote is free and usually same day.
Every array is quoted individually, because these are the factors that actually move the number:
| Factor | Why It Moves The Price |
|---|---|
| Panel count | Setup happens once, so larger arrays cost less per panel than small ones |
| Roof height and pitch | A steep two-story roof takes more rigging and slower footwork than a ground mount |
| Soiling level | A yearly maintenance wash moves fast; years of baked-on grime takes extra passes |
| Bird activity | Heavy droppings and nesting debris under the array add soak and removal time |
| Bird proofing add-on | Mesh installation is priced by the array perimeter and quoted up front |
| Bundled services | Adding windows, gutters or a house wash to the visit skips a second trip charge |
Here is the honest math. If soiling is costing a typical SoCal array 15 to 25 percent of its output, a cleaning usually pays for itself well before the next one is due. Tell us your panel count and roof type and we will give you an exact number, free, with zero pressure. Call or text 747-202-3622 or request a fast quote.
One thing we will not do is guess at electrical work. Panels, wiring and inverters belong to your solar installer. We keep the glass producing and tell you honestly when something needs a different trade.
The track record is public: reputation for consistent, careful work, licensed and insured, family owned and operated out of the San Fernando Valley. You get the same crew every visit, so the technician on your roof next year already knows your array, your roof and your gate code. Hear it from your neighbors on our reviews page, and if you are deciding on a cadence, our guide on how often solar panels should be cleaned in California lays out the schedule that fits your area.
From the coast to the foothills, one crew covers it all. We clean solar arrays throughout Los Angeles County and Ventura County.
The crew is already on your roof with purified water on board. Most solar customers knock out the rest of the exterior in the same morning.
