Fast, Reliable Solar Panel Cleaning Across West Hills
Solar panel cleaning in West Hills runs $150-$300 for a typical residential array, and most of our West Hills appointments are completed within a week of your call. Gus’s Solar has been cleaning panels in the 91307 and 91308 ZIP codes long enough to know exactly what the Santa Ana winds, sycamore debris, and local pigeon activity do to a system’s production over the course of a year. The answer never changes: dirty panels lose real kWh, and on most West Hills homes we see that loss reach 15-25% before homeowners notice it. Call (877) 550-6892 for an honest assessment and a fixed price. Gus Petrakis answers his own phone, and he’ll tell you straight whether your panels need cleaning now or in six months.
Why Gus’s Solar Is West Hills’s Preferred Solar Panel Cleaning Company
We’re not a national franchise with a call center three states away. Gus’s Solar is Gus Petrakis, his crew, and a published address on the truck. West Hills homeowners have been calling us since 2011 because we show up when we say we will, we do the work ourselves, and we don’t send a different subcontractor every visit. That matters when someone is on your roof, walking around a $30,000 solar system.
West Hills reviews consistently mention the same things: a live person answered the phone, the tech explained what was being cleaned and why, and the crew left no mess behind. Our response time to West Hills is typically same-week, and for post-storm cleaning requests we do our best to be there within 24 to 48 hours. The crew knows the streets out here. We’ve worked homes off Platt Avenue, Vanowen Street, and Valley Circle Boulevard. We know how the marine air that filters through Bell Canyon affects panel frames, and we know what a Santa Ana wind event leaves on a rooftop near the Santa Susana foothills.
Gus started this company after watching too many homeowners get quoted one price on the phone and another at the door. He runs Solar Panel Cleaning the same way he runs every other part of the business: upfront pricing, no signature wanted tonight, and a 90-Day Done Right Promise on every job. If the cleaning isn’t done right, he comes back and makes it right. That’s not marketing language. That’s how we’ve operated in West Hills for years.
Our Solar Panel Cleaning Services in West Hills
Residential Panel Cleaning
Residential panel cleaning in West Hills typically runs $150-$300 depending on the array size, roof pitch, and how long it’s been since the last cleaning. We use deionized water and soft-bristle brushes, never abrasive scrubbers, and never pressure washers that can crack glass or force water into junction boxes. Most single-story ranch homes on the flat interior of West Hills take us under two hours from ladder to ladder. Two-story hillside homes with steeper pitches take longer and cost more, because we’re working with harnesses and roof anchors.

Commercial Array Cleaning
For commercial rooftops in West Hills, including small office parks and retail buildings near Fallbrook Center and the West Hills Medical Center area, we schedule cleanings on a recurring basis so production loss never becomes a line-item problem on your P&L. Commercial arrays in West Hills run $0.10-$0.25 per panel per cleaning, depending on the total array size and access. We’ll document before-and-after production readings so you can see the delta clean panels make.

Bird & Critter Guard Installation
Pigeons are the single biggest wildlife problem for West Hills solar owners. They nest under the eaves of 1960s and 1970s ranch homes and under the panels themselves, and their droppings etch anti-reflective coatings and clog drainage channels. Installing galvanized or PVC-coated wire mesh along panel edges runs $500-$1,200 for most West Hills residential arrays. We install the mesh so water still flows off the roof, and we trim it flush so it doesn’t look like a DIY job. If you’re already seeing droppings on your panels, the guard install should happen sooner, not later.

Debris & Soiling Removal
After a Santa Ana wind event, panels across West Hills pick up a fine layer of grit from the Simi Hills, plus sycamore leaves, eucalyptus bark, and whatever else the wind carried. We do post-storm debris removal as a same-day or next-day service when it’s needed. The debris collects along the lower edges of arrays, especially on hillside homes around Bell Canyon Road and the northern sections of West Hills. If left for a few weeks, those patches become localized hotspots that stress the cells underneath. We see it regularly. We clean it every time.

Trusted Brands We Service in West Hills
West Hills is loaded with older solar installs and newer high-efficiency systems, and we service all of them. The bulk of what we clean in this area is Tesla panels, largely because the Tesla install wave hit West Hills hard in the late 2010s and those arrays are now hitting the age where soiling loss really shows up. We also see a lot of Panasonic and SunPower systems, particularly on the larger custom homes in the hillside sections. Our cleaning protocol is the same across brands: deionized water, soft brushes, and no chemicals that could leave a film. We also carry the common mounting hardware and critter guard components for these systems, so when we find a loose clamp or a gap where birds are getting in, we typically fix it on the same visit.
Common Solar Panel Cleaning Problems We See in West Hills Homes
- Pigeon droppings concentrated under eaves. The ranch-style homes that dominate flat West Hills have wide eaves, and pigeons love them. The droppings etch panel glass, clog water channels, and create shaded spots that burn out cells faster than the normal 0.5% annual degradation. We install critter guard mesh on nearly half the West Hills arrays we clean.
- Santa Ana wind debris and fine grit. High wind events peel leaves and bark from sycamores and eucalyptus across the Simi Hills and drop them directly onto panel arrays. The grit that follows embeds along lower panel edges and causes hotspots that slowly degrade output.
- Marine-air oxidation on panel frames. West Hills sits at the western mouth of the San Fernando Valley, and the marine-influenced air that pushes through means panel frames and mounting hardware oxidize faster than homeowners expect. Loose clamp torque from corrosion can cause microcracks in glass, especially during high wind gusts when the panels flex.
- Hard water spotting from sprinkler overspray. Panels on homes with landscaped yards near Vanowen Street and Platt Avenue get hit by sprinkler overspray that bakes into an opaque film. That film doesn’t just reduce production, it bakes onto the panel surface over time and gets progressively harder to remove.

FAQs - Solar Panel Cleaning in West Hills
West Hills falls entirely within LADWP service territory, and interconnection approvals here routinely add three to six months after city permitting. That means your array may sit idle, unapproved, and exposed to dust and bird activity for a full season before it ever produces a credit. We recommend scheduling a cleaning during that window, ideally in the two weeks before your LADWP sign-off inspection. That way, the system is running at full production from the first day it’s approved, and the inspector sees a properly maintained array. Call (877) 550-6892 and we’ll coordinate the timing with your permit schedule. You should not be guessing on this.
Yes, and the West Hills math makes the cost visible quickly. LADWP’s Net Billing Tariff credits you at a rate that is already less generous than older net metering structures. One heavily soiled or bird-dropped panel can cut that array’s production by 10-25%. Over a West Hills summer, with 5.7-5.8 peak sun hours a day, that’s real money. A $200 cleaning that restores the array’s output pays for itself in one billing cycle for most customers. If you’re seeing droppings, call (877) 550-6892 and we’ll tell you honestly whether the loss is significant or if it can wait.
Most West Hills homeowners need a cleaning once a year, but the fall and early winter Santa Ana season is the real trigger. If a big wind event comes through, the panels are going to be coated in dust and debris. Homes in the hillside sections near the Santa Susana foothills see more grit than the flat interior. Homes with eucalyptus or sycamore trees nearby need it more often. Marine air itself doesn’t require more cleaning, but it does make whatever lands on the panels stick harder, so waiting two years between cleanings leaves a baked-on film that takes longer to remove.
If you see pigeons anywhere near your roof, the answer is almost always yes. Pigeon activity in West Hills is heavier near the ranch home eaves and the commercial rooftops around Fallbrook Center, but the birds don’t respect property lines. Droppings acid-etch panel glass, clog drainage channels, and attract more birds. Our bird and critter guard installation runs $500-$1,200 for most West Hills residential arrays and includes trimming the mesh so it doesn’t look like a bare-wire fence on your roof. Call (877) 550-6892 and we’ll give you a straight answer after seeing your roof.
Cleaning your panels won’t change what your inverter’s monitoring software estimates for a perfectly clean array. What it does is bring your real-world output back in line with that estimate. When we clean a West Hills array, we often see production rebound by 15-20% within the first full day of operation. Over the life of a solar system, regular cleaning is the difference between hitting the year-25 output number or falling short of it. Gus Petrakis quotes the year-25 output, not the day-one brochure number. Same principle applies to cleaning.
