Why Gus’s Solar Is San Rafael’s Preferred Solar Panel Cleaning Company
We’ve been cleaning panels in San Rafael long enough to know which neighborhoods fight pollen and which ones fight road grime off Highway 101. Customers in Sun Valley and the Dominican area call us about ridge shading and tree sap, while Terra Linda homeowners see mineral etching from sprinkler overspray on ground-mounted arrays. That local pattern recognition means we show up with a plan, not a generic checklist.
Gus Petrakis founded this company in 2011 and still answers his own phone. Every cleaning job is backed by our 90-Day Done Right Promise: if the panels aren’t clean, we come back. No argument, no re-invoice. Our technicians are background-checked and uniformed, and they’re Gus’s own crew, not subs. When you schedule a cleaning in San Rafael, the person who confirms the time can tell you which side of 94901 you live in before you finish spelling the street name.

Our Solar Panel Cleaning Services in San Rafael
Residential Panel Cleaning
A standard residential cleaning in San Rafael covers the full array, edge-to-edge, using deionized water and soft brushes that won’t scratch the glass or void your panel warranty. We handle everything from compact 12-panel systems on Craftsman-era homes in Gerstle Park to full 30-panel arrays on Terra Linda ranches. Most residential jobs take under two hours, and we work around your schedule, including early mornings before the roof gets hot.
Bird & Critter Guard Installation
San Rafael’s mature oaks and eucalyptus trees mean pigeons and squirrels are a real threat to your array. Bird droppings baked onto panels by our summer sun can reduce output on affected cells by 10 to 15 percent, and pigeon nests under panels trap heat and moisture against the wiring. We install galvanized critter guard around the entire perimeter of the array, and we can do it in the same visit as a cleaning. For hillside properties near Dominican, we also check for evidence of roof rats, which are active in that area.
Debris & Soiling Removal
This is the deep clean service for San Rafael arrays that haven’t been touched in a year or more. We remove caked-on dust from the Highway 101 corridor, pollen residue, sap from overhanging trees, and the fine gray film that accumulates in 94901 during dry months. The difference is visible through the Enphase app before we’re off the roof.
Scheduled Cleaning Plans
We offer quarterly and semi-annual cleaning plans for San Rafael homeowners who want the array producing at its year-25 numbers, not just the day-one brochure figure. Scheduling is based on this city’s actual soiling patterns: a spring cleaning after the oak and eucalyptus pollen peak, and a fall cleaning after wildfire smoke and dry-summer dust. Bring us a bill, Gus will bring you the math on what each lost percentage point costs you in true-up dollars.

Trusted Brands We Service in San Rafael
We clean and inspect arrays built on Panasonic, Canadian Solar, and FranklinWH equipment, and our crew is trained on microinverter and string systems alike. When we service a San Rafael array, we check the inverter cabinet and panel mounting hardware at the same time, because salt-laced bay haze drifts inland enough to accelerate corrosion on exposed components. If a connector is wearing or a mount looks loose, we’ll tell you before it becomes an outage. We don’t sell you a cleaning and ignore what we see.
Common Solar Panel Cleaning Problems We See in San Rafael Homes
- Bay-area marine haze films: San Rafael sits inside the bay’s haze path but far enough inland to get serious sun, so the film that forms on glass is a dust-haze combination that bakes on hard. A 1-millimeter film across a south-facing array in 94901 can quietly trim 4-5% of daily production.
- Eucalyptus and oak pollen buildup: Hillside neighborhoods in San Rafael, including the slopes above downtown and around Dominican, produce heavy spring pollen that clogs panel edges and traps heat. That edge buildup reduces airflow under the panel and lifts cell temperature enough to matter in June.
- Sprinkler overspray mineral etching: Ground-mounted arrays near Terra Linda lawns get hit by hard-water overspray from irrigation. The calcium and magnesium deposits left behind don’t just block light; over repeated seasons they can etch the glass surface permanently, which no cleaning will fix.
- Bird droppings from pigeon roosts: San Rafael’s older roofs and large trees provide roosting spots for pigeons, especially in the 1920s-40s housing around Gerstle Park and downtown. Droppings on panels act like shade, but they can also contain grit that microscratches the glass during rain or wind.

FAQs - Solar Panel Cleaning in San Rafael
Twice a year is the right rhythm for most San Rafael homes: once in late spring after the oak and eucalyptus pollen peak, and once in early fall after the dry summer dust and any wildfire smoke has settled. For ongoing Solar Panel Maintenance & Monitoring - San Rafael between cleanings, we track your system’s performance year-round. If you live near Highway 101 or in a neighborhood with active construction, a third cleaning in mid-summer often pays for itself. Call (877) 550-6892 and Gus can look at your production data to tell you if your array is due.
Yes, but not in the way most people think. San Rafael gets the bay’s haze and some salt-laced air, which combines with valley dust from the 101 corridor to form a fine gray film that bakes on under the city’s strong inland sun. Coastal Marin towns get fog and less sun; drier inland cities get dust but less haze. San Rafael gets enough of both to make a measurable production difference. A thin film on a 94901 array can trim 4-5% of output without looking visibly dirty.
Yes, if left through a summer. Droppings baked on by San Rafael’s summer heat can etch the antireflective coating on panel glass, which no cleaning will restore. In Terra Linda specifically, pigeon activity is common around the flat ranch roof lines, and droppings on a south-facing array in that neighborhood can reduce output on the affected cells by 10-15%. If you’re seeing droppings, call us sooner rather than later, and we can quote the cleaning and a critter guard in the same visit. We also handle San Rafael Solar Panel Repair if the damage has already occurred.
Compare your Enphase or SolarEdge daily production before and after the cleaning, or look at month-over-month output in your monitoring app. After our Terra Linda ranch cleaning last spring, we confirmed a 6% production lift on a 24-panel REC system via the homeowner’s Enphase app before we left the driveway. We apply the same rigor to every job, including Commercial Solar Installation - San Rafael projects we maintain. That’s the standard we hold ourselves to: a verifiable change in output, not just cleaner glass. Call (877) 550-6892 and we’ll do the same check on your system.
Yes, within two to three weeks after the smoke clears. Wildfire ash is fine, alkaline, and sticky, and San Rafael sits in the drift pattern for fires to the north and east. Even light ash accumulation can cut production by 5-8%, and if dew or fog mixes with the ash, it forms a film that’s harder to remove than the dry dust of normal San Rafael conditions. Post-storm and post-smoke cleanings are something we do regularly for 94901, 94903, and 94912 homeowners.
