Why Gus’s Solar Is San Martin’s Preferred Solar Panel Cleaning Company
Gus Petrakis put his own name on this business back in 2011, and he’s the one you’ll talk to when you call. That matters in a place like San Martin, where a handshake still counts and a disappearing contractor gets remembered longer than a good one.

The work is consistent: honest numbers, no pressure, and a live person answering the phone 24/7.
Our Solar Panel Cleaning team handles everything from a quick rinse on a 20-panel roof system to a full production recovery on a 48-panel ground mount. We show up with soft brushes, deionized water, and enough experience with San Martin’s particular grime that we don’t need to guess.

Our Solar Panel Cleaning Services in San Martin
Residential Panel Cleaning
A typical rooftop array in San Martin runs $180-$340 to clean, depending on panel count and roof pitch. Most of the homes here are single-story ranches from the 1950s through 1980s, which means access is straightforward and the job moves fast. We clean the glass, check the racking bolts while we’re up there, and confirm your production numbers look right afterward. Call (877) 550-6892 for a quote specific to your system.
Commercial Array Cleaning
Barn roofs, equipment sheds, and small farm offices in San Martin often carry 40-100 panels that haven’t been cleaned since the day they went up. Commercial cleaning runs $350-$900 depending on array size and access. A dirty 60-panel barn system can easily lose 10-15% of its output to baked-on dust from the Diablo Range foothills. We schedule around your operation’s rhythm so we’re not in the way during feeding or shipping hours.
Bird & Critter Guard Installation
If you’ve got panels on a barn or ground mount in San Martin, you’ve probably got pigeons, starlings, or ground squirrels making themselves at home under the rails. Critter guard installation runs $2.50-$4.50 per linear foot, installed. We use a galvanized mesh that holds up to the valley’s afternoon thermal winds. One ranch out near the corner of San Martin Avenue and Foothill Avenue had ground squirrels chewing wire jackets on the lower rails; the guard stopped that in an afternoon.
Debris & Soiling Removal
San Martin doesn’t get much rain during the dry season, so whatever lands on your panels stays there. Equestrian properties kick up fine arena dust and hay chaff that settles on low ground-mount arrays. For $150-$300, we’ll clear the debris, wash the glass, and show you the before-and-after production numbers from your monitoring portal. It’s the fastest way to know if your system is dirty, degraded, or both.

Trusted Brands We Service in San Martin
We clean and maintain arrays from Tesla, Enphase, SolarEdge, and FranklinWH, among others. Most of what we see in San Martin is Enphase microinverter systems on older roof mounts plus a growing number of SolarEdge string systems on barn and ground-mount installs. If a post-storm cleaning reveals your system hasn’t been reporting data, we’ll tell you. We don’t sell you a replacement unless the numbers say you need one.
Common Solar Panel Cleaning Problems We See in San Martin Homes
- Baked-on dust film from the Diablo Range foothills. San Martin sits south of the marine-layer fog belt, so panels here can go weeks without any rain to wash them. Fine dust settles, the sun bakes it on, and production drops 5-15% before anyone notices.
- Irrigation overspray and hard-water spotting. Many properties run well pumps and irrigation controllers near ground mounts. Overspray leaves mineral deposits that a garden hose can’t remove and actually makes the panel retain more dust afterward.
- Critter damage under ground-mount rails. Ground squirrels and roof rats like the sheltered space under low arrays. They chew wire jackets, build nests, and leave debris that traps heat and blocks airflow. The fix is guard mesh, not more cleaning.
- Silent production failures on older ranch systems. A lot of San Martin’s 1950s-1980s ranch homes have original panels paired with inverters that stopped reporting months ago. A cleaning call sometimes turns up a system that’s been dead on the monitoring side for half a year. We’ll tell you what we find.

FAQs - Solar Panel Cleaning in San Martin
You can realistically lose 5-15% of your array’s output by the end of a dry San Martin summer. Hot inland air, no fog, and fine dust from the Diablo Range foothills combine into a baked-on film that ordinary rain wouldn’t remove even if it came. The real cost shows up in a lower kWh offset on your annual true-up statement, not in a single dramatic number. Call (877) 550-6892 and we’ll give you an estimate based on your actual system size and how dirty the glass looks when we see it.
Cleaning fixes soiling, but it won’t fix degraded panels, failed microinverters, or a monitoring system that stopped reporting months ago. San Martin has a lot of 1950s-1980s ranch homes whose original solar installs lack rapid shutdown labeling or modern inverter communication. We’ll clean the array, then check the production numbers against what a healthy system your size should produce. If the shortfall persists, we’ll tell you the truth about what’s causing it and whether it’s worth fixing.
No. Routine panel cleaning doesn’t require a permit from Santa Clara County’s Department of Planning and Development. That said, San Martin is an unincorporated area, so any actual repair work or electrical changes involving your system route through the county rather than a city building department. We coordinate with the county when a cleaning turns up something that needs a repair. That’s just how it works in San Martin, and we’re used to the timeline.
Yes, and they often do. Ground squirrels and roof rats chew wire jackets, strip insulation, and build nests under ground-mount rails that trap heat and block airflow. A clean panel can’t produce well if its conductors are chewed through or its underside is packed with debris. If you’ve got critter activity, we’ll recommend guard mesh along the lower rails at the time of the cleaning. It’s cheaper than replacing wiring after the damage is done.
In many cases, yes. A lot of San Martin barn arrays are silently underperforming because they’re dirty, not because the panels are shot. We clean them, check the production data, and compare the numbers against what a 15-year-old system of that size should produce. If the panels recover to within a few points of the design output, you’ve saved yourself a replacement. If they don’t, you’ll know exactly how far gone they are before you spend real money. Call (877) 550-6892 and we’ll give you the straight answer either way.
Local Conditions That Make Cleaning in San Martin Different
San Martin sits far enough south of the marine-layer fog belt that panels here can stay dry for weeks at a stretch. That’s great for daily production, but it means whatever lands on the glass stays there. Fine dust off the Diablo Range foothills bakes into a film that a garden hose cannot remove, and the longer it sits, the tighter it bonds. Equestrian properties make it worse: arena dust and hay chaff linger in the air and settle on low ground-mount arrays, where they get mistaken for panel degradation until a proper cleaning restores the expected output. And because San Martin is unincorporated, any electrical or repair work tied to your array goes through Santa Clara County, not a city hall. Our team is familiar with that process and plans around it.
A Real Call We Ran in San Martin
Out on a ranch near the corner of San Martin Avenue and Foothill Avenue, our techs found a 48-panel ground-mount array coated in a mix of irrigation overspray and wind-blown soil from the horse arenas. The microinverters were reporting a 22% production shortfall versus the original production estimate, and the panels had an obvious film that a garden hose couldn’t touch. We ran our deionized-water system with soft brushes, then added bird-and-critter guard along the lower rails where ground squirrels had been chewing wire jackets. The homeowner’s next true-up statement showed their kWh offset back within a few points of the design number. That’s the kind of result cleaning is supposed to deliver, and it’s why we don’t guess when we quote a job.
