Why Gus’s Solar Is Windsor’s Preferred Solar Panel Cleaning Company
Gus Petrakis puts his name on every job, and that matters in a town like Windsor. You’ll see the same face at Foothill Regional Park or grabbing coffee on McClelland Drive that you saw on your roof. Founded in 2011, we’re not a pop-up crew or an out-of-state outfit running ads during fire season. We’re local, we’re reachable, and a real person answers the phone 24/7, no voicemail maze, no ticket queue.
Windsor homeowners call us because we understand the specific pressures here: HOA architectural review boards in planned subdivisions, PSPS outage anxiety, and the fine print on Sonoma Clean Power true-up statements. Our Solar Panel Cleaning team does the work itself. We don’t hand it off to a sub. And every job carries the 90-Day Done Right Promise: if it’s not done right, Gus makes it right, in writing.
We also answer our own reviews. Windsor customers have left us strong feedback over the years for showing up on time, respecting HOA work-hour rules, and quoting a price that matched the invoice. The number we give you is the number you pay. No signature wanted tonight. Take two weeks. Think about it. The price will be the same.
Our Solar Panel Cleaning Services in Windsor
Residential Panel Cleaning
A standard single-story Windsor home with a 20-28 panel array takes our crew about two hours from setup to rinse. We use filtered water systems calibrated for Windsor’s hard well water, which prevents the mineral spotting that cheap deionized rigs leave behind on anti-reflective coatings. Two-story stucco homes in the Lakewood and Windsor Oaks tracts are no problem; we bring the right ladder and safety gear for every roof pitch.
Debris & Soiling Removal
Windsor’s dry summer months from May through October bring fine dust, pollen, and sometimes wildfire ash that cakes onto panels and quietly trims production. A light dusting is normal. A visible film that turns rainwater brown means you’re losing measurable output. We remove caked-on debris without scratching the glass, then check your production readout against your system’s baseline to confirm the cleaning actually restored your numbers.
Post-Storm Panel Cleaning
After a windy spring storm or a fire-season ash event, panels in Windsor collect a gritty layer that rain alone won’t remove. We send a crew to inspect, wash, and document the condition of your array, and we’ll flag any microcracks or mounting issues we see while we’re up there. If you’re on Sonoma Clean Power’s net metering, a post-storm cleaning often pays for itself within the same billing cycle.
Bird & Critter Guard Installation
Pigeons and roof rats are a real issue in Windsor’s subdivisions, especially where mature oaks overhang roofs. Droppings under panels create hot spots and can corrode wiring over time. We install critter guard around the array perimeter and clean out existing nesting material. This isn’t a side service for us; it’s part of keeping your system running at the output we quoted you.

Trusted Brands We Service in Windsor
We clean and maintain residential arrays built on Panasonic, Qcells, REC, and Canadian Solar modules, plus Tesla systems and Enphase or SolarEdge inverters and microinverters. Our crew is trained on the mounting hardware and torque specs for each brand, so a cleaning never turns into a repair. If we spot a failing microinverter or a loose rail while we’re up there, we’ll tell you. We keep common replacement parts and cleaning supplies stocked for Windsor jobs, which means faster turnaround when your array needs more than a rinse.
Common Solar Panel Cleaning Problems We See in Windsor Homes
- HOA work-hour rule violations. Several Windsor subdivisions, including Windsor Oaks, restrict roof work to specific hours and require approved vendors. We check before we schedule, so you don’t get an ARB notice in your mailbox after a routine cleaning.
- Mineral spotting from hard well water. Windsor’s water has high dissolved mineral content. Rigs that don’t filter properly leave calcium spots that bake onto the glass in summer sun, reducing output on panels with anti-reflective coatings. We use the right filtration for this specific water profile.
- Ash and dust cementation after fire season. Fine ash from regional fires mixes with morning dew and hardens into a film that a standard garden hose won’t budge. It needs a proper wash with the right water pressure and a soft brush, not a pressure washer.
- Bird activity under arrays. Mature landscaping around Lakewood and older Windsor streets creates nesting sites. Droppings don’t just look bad; they cause uneven heat and can accelerate wiring degradation. We offer critter guard installation as a long-term fix.
Pricing for Solar Panel Cleaning in Windsor, CA
A typical residential panel cleaning in Windsor runs $150-$225 for a single-story array up to 24 panels. Two-story homes or arrays with significant soiling run $200-$325. Bird and critter guard installation starts around $400 and goes up with linear footage. Post-storm ash removal is usually $180-$280 depending on panel count and access.
What moves the price: roof pitch, panel count, how much debris has accumulated, and whether HOA scheduling rules split the job across multiple visits. We give you one number up front and it doesn’t change at the door. Senior and veteran customers save 10% every time, no expiration. Call (877) 550-6892 and bring me a bill, I’ll bring you the math.

FAQs - Solar Panel Cleaning in Windsor
If you’re on Sonoma Clean Power’s net metering in Windsor, clean your panels twice a year, once in late spring after pollen season and once in late fall after fire season. SCP’s export credit structure is different from PG&E generation rates in Santa Rosa or Healdsburg, so the dollar value of each lost kilowatt-hour isn’t identical. Your cleaning frequency should follow your actual production data, not a generic recommendation. Call (877) 550-6892 and we’ll pull your readout and tell you honestly whether a cleaning will pay for itself.
Yes, some Windsor HOAs do. Subdivisions like Windsor Oaks and Lakewood have architectural review boards with approved vendor lists and work-hour restrictions. We check your HOA’s rules before scheduling and keep a record of compliance, so a simple cleaning never turns into a violation letter. We’ve worked inside these HOA frameworks for years and know the paperwork.
Yes, bird droppings under your Qcells or REC panels in Windsor’s dry summer heat can cause hot spots and accelerate corrosion of wiring and connectors. Windsor’s mature oaks and warm, dry climate create ideal nesting conditions for pigeons. We remove the droppings, clean the affected area, and install critter guard to keep birds from returning. Call (877) 550-6892 for a quote.
No, a standard garden hose rinse is usually not enough after Windsor’s fall ash events. Ash mixes with dew and hardens into a cement-like film that blocks light and resists normal water pressure. Tesla panels tolerate a proper soft-brush wash with filtered water, but a pressure washer can void your warranty. We use the right water pressure and filtration for Windsor’s water hardness and leave your panels clean without scratching the glass.
Sometimes, but not always. A drop in your inverter’s production readout in Windsor can come from soiling, but it can also signal a failing Enphase microinverter, a shaded array, or a communication issue. We cleaned a 2018-installed SunPower array in Lakewood after pollen and dust buildup dropped the system’s production estimate by 11%, and the cleaning restored it fully. But if cleaning doesn’t fix the readout, we diagnose the inverter rather than guessing. Call (877) 550-6892 and we’ll investigate.
