Most cleanings take 60-90 minutes on-site, and we can usually be at your door within 24-48 hours of your call.

We’re not a pop-up crew. Gus Petrakis founded Gus’s Solar in 2011, and his name is on every truck that rolls into Sherman Oaks. We know the valley dust, the Santa Ana ash, and the way pollen settles into the shallow gable valleys on those 1950s ranch roofs north of Ventura Blvd. This isn’t a generic spray-and-wipe job. It’s about protecting the kWh your system produces for LADWP’s net metering true-up, and doing it right the first time.
Why Gus’s Solar Is Sherman Oaks’s Preferred Solar Panel Cleaning Company
Sherman Oaks homeowners tell us the same story again and again: they had a national outfit install the panels, got one quote on the phone and a different number at the door, and then never saw the company again. That’s not how we work. Gus answers his own phone. The crew that shows up is background-checked, uniformed, and employed by Gus’s Solar, not handed off to a subcontractor.
We’re local in the way that matters. We know that LADWP’s interconnection queue runs 8-14 weeks behind schedule, and we know that a skipped cleaning on a dusty Sherman Oaks roof doesn’t just look bad, it costs you money on your annual true-up statement. Customers near Kester Ave, Van Nuys Blvd, and the hillside streets south of Ventura Blvd call us because we show up when we say we will and charge what we quoted. Every job carries the 90-Day Done Right Promise. If it’s not right, Gus makes it right, and one call brings him back.
Our Solar Panel Cleaning Services in Sherman Oaks
Residential Panel Cleaning
A typical Sherman Oaks home with 20-28 panels costs $150-$280 to clean. We use deionized water and soft-bristle brushes, never tap water with minerals that leave spots, and never high-pressure spray that can crack a cell. On the low-pitched ranch roofs north of Ventura Blvd, we pay special attention to the shallow gable valleys where valley dust and pollen collect and cut generation faster than on steeper modern builds.
Debris & Soiling Removal
Between the San Fernando Valley’s trapped heat and the Santa Ana winds, panels in Sherman Oaks collect a film of dust, ash, and pollen that can cut output by 8-14% within a few dry weeks. We remove it all. After a deep deionized wash on a 24-panel REC array near Kester Ave, the homeowner’s Enphase microinverters showed daily kWh offset snap back to within 4% of original design performance. That’s the difference a real cleaning makes.
Bird & Critter Guard Installation
Pigeons love the space under solar panels, especially on single-story ranch homes where the array is close to mature trees. Nests block airflow, droppings corrode wiring, and the mess attracts more birds. We install powder-coated mesh guard along the racking channels, sized to keep birds out while leaving the panel-to-roof gap open for ventilation. This matters more in Sherman Oaks than coastal LA, because rooftop ambient temps above 90°F in summer make blocked airflow a real performance killer.
Commercial Array Cleaning
For apartment buildings, retail rooftops, and office parks along Ventura Blvd, we clean larger commercial arrays at $0.08-$0.15 per watt depending on access and tilt. We schedule around your business hours and provide before-and-after production data so you can see exactly what the cleaning recovered. Commercial owners in Sherman Oaks deal with the same LADWP true-up math as homeowners, just with bigger numbers on the line.

Trusted Brands We Service in Sherman Oaks
We clean and maintain systems built on Qcells, REC, SunPower, and Panasonic panels, plus Enphase and SolarEdge inverters. Because we install and service these same brands, we don’t have to guess at torque specs, grounding points, or warranty requirements. If a cleaning reveals a loose connector or a microinverter flag, we’re qualified to fix it on the spot, not just note it and leave you to find someone else.
Common Solar Panel Cleaning Problems We See in Sherman Oaks Homes
- Valley dust collecting in shallow gable valleys. Those 1950s and 1960s ranch roofs north of Ventura Blvd were built with low-pitch gables. Dust and pollen settle into the shallow valleys and don’t wash away with rain, cutting generation more than on steeper modern rooflines.
- Santa Ana ash after wind events. Every October and November, the winds push fine ash across the Valley. It bakes onto panel glass in the heat and requires a deionized wash to remove without scratching or spotting.
- Bird activity under panel arrays. Once pigeons establish a nest under your array, they stay. The droppings corrode wiring over time, and the nesting material blocks the ventilation gap that keeps your Enphase microinverters from thermal derating on hot afternoons.
- Inverter dust buildup and thermal shutdown. Sherman Oaks summer rooftop temps routinely pass 90°F. A dust-caked inverter or a blocked panel-to-roof gap can trigger rapid shutdown or derating during peak billing hours, which is exactly when LADWP rates are highest.

A standard residential panel cleaning in Sherman Oaks runs $150-$280 for most single-story homes.

FAQs - Solar Panel Cleaning in Sherman Oaks
LADWP’s net metering program settles your bill once a year based on the actual kWh your system produced and offset against your usage. If dirt and soiling cut your production by 8-10% for even a few months before that true-up snapshot, those lost kWh translate directly into a higher annual bill. Cleaning your panels before LADWP’s billing snapshot locks in the full offset you designed the system for. For exact timing on your billing cycle, call (877) 550-6892 and we’ll check what makes sense for your setup.
Generally yes, twice a year is right for most ranch homes on the valley floor, compared to once a year for steeper hillside arrays. The low-pitch gable roofs on post-WWII ranches hold dust and pollen in the valleys where water doesn’t sheet off as efficiently. Add the San Fernando Valley’s trapped heat, and the soiling bakes on faster. A spring cleaning after pollen season and a fall cleaning after Santa Ana winds keeps most systems running near design output.
Yes. Nesting material and droppings block the airflow gap between panel and roof, and blocked airflow raises microinverter operating temperatures. When rooftop ambient temps are already above 90°F in Sherman Oaks summer, that extra heat can push Enphase microinverters into thermal derating or shutdown. Installing bird guard along the racking channels keeps the gap clear and the inverters cooler. We do this as part of our cleaning service when we see evidence of birds.
No, not when it’s done properly. Qcells, REC, SunPower, and Panasonic all require periodic cleaning to maintain their production warranty terms. Using deionized water and soft brushes meets the manufacturers’ care guidelines. Using tap water with high mineral content or a pressure washer can leave spots or micro-cracks, which is why we don’t do either. If you’re concerned about warranty language, call us, and we’ll walk through what applies to your specific panel brand.
Cleaning doesn’t change your panels’ underlying degradation rate, but it restores output to the level your system was designed for. A panel operating at 92% of nameplate because of soiling is performing like a much older panel. After our deionized-water wash on a dusty Sherman Oaks array, we typically see daily kWh production return to within 4-6% of the original design estimate. That’s the margin that shows up on your LADWP true-up statement as a credit instead of a charge. For a free production check, call (877) 550-6892.
If your panels haven’t been cleaned in over a year, or you’re seeing a dip in your Enphase or SolarEdge daily production numbers, call us at (877) 550-6892. We’ll give you a straight answer, a firm price, and a time we’ll be there. Gus Petrakis’s name is on the work, and it’s been that way since 2011.
