AfterFast, Reliable Solar Panel Cleaning Across Winters
Dirty panels in Winters don’t just look bad. They quietly eat your production, and on a PG&E agricultural rate with demand charges, that lost output shows up on the bill fast. We clean residential and farm arrays throughout 95694, usually within a few days of your call. Gus Petrakis owns Gus’s Solar, answers his own phone, and sends his own background-checked crew to Winters. Call (877) 550-6892 for a free estimate. No pressure, no overnight decisions. Just a straight answer about what your panels need.
Why Gus’s Solar Is Winters’s Preferred Solar Panel Cleaning Company
We’ve been cleaning panels in Winters long enough to know the rhythm of this town. The fog season, the harvest calendar, the way dust settles differently on a downtown Victorian roof versus a pole-mount array off Russell Boulevard. Local knowledge like that isn’t something you get from a pop-up crew running a Facebook ad.
Winters homeowners tell us the same thing: they want a name they can verify and a face they’ll see again at the hardware store. That’s Gus. Founded in 2011, locally owned since day one, with a 90-Day Done Right Promise in writing on every job. If it’s not right, Gus comes back and makes it right. One call does it.
Our crews know the access constraints in Winters’s older neighborhoods. Tight driveways off Main Street. Steep metal roofs on ag buildings east of town. Ground-mount arrays tucked behind walnut orchards. We plan for that. We don’t send someone out who’s seeing it for the first time.
Our Solar Panel Cleaning Services in Winters
Residential Panel Cleaning
A typical residential array in Winters runs $150 to $300 per cleaning, depending on panel count, roof pitch, and how much agricultural dust has baked on. We hand-wash with deionized water and soft brushes. No high-pressure spray, ever. That matters here, where hot summers bake residue onto glass and make it feel like concrete if you wait too long. Our Solar Panel Cleaning team leaves panels spotless without stressing the glass, the seals, or the microinverters underneath.
Commercial Array Cleaning
For Winters’s farm operations, packing sheds, wineries, and small commercial roofs, we quote by panel count and site access. Commercial arrays in the 100 to 500 panel range typically run $800 to $2,500 per cleaning in Winters, with scheduled plans bringing the per-cleaning cost down. We work around harvest schedules and irrigation cycles. If you’re on a PG&E AG rate, the math on clean panels changes quickly. Demand charges don’t care if your panels are dirty, but your production does.
Bird & Critter Guard Installation
Pigeons love the shade under a ground-mount array. We see it constantly out along Railroad Avenue and the ag parcels west of town. We install critter guard after cleaning, and we install it right the first time. The guard runs $12 to $18 per linear foot installed, depending on the rail system and access. It’s the cheapest insurance you can buy against nesting damage and droppings that bake onto glass in July.
Debris & Soiling Removal
Almond harvest dust, olive pollen, grass clippings, leaf litter from downtown’s old trees. All of it lands on panels. We remove it carefully, without scraping glass or forcing debris into the gaps between panels. For Winters homes with tall trees or fields nearby, a scheduled cleaning plan makes more sense than waiting for production to drop. We’ll talk through what we’re seeing on your array and what it actually needs.

Trusted Brands We Service in Winters
We clean and maintain panels from every major manufacturer. In Winters, we see a lot of Panasonic and Canadian Solar on residential roofs, plus JinkoSolar on larger ag installations. We also service systems paired with FranklinWH batteries. Our crew knows the mounting systems, the rail profiles, and the places where dust and debris accumulate on each. We stock common parts and guards locally, so a Winters service call doesn’t drag out waiting on a shipment from somewhere else.
Common Solar Panel Cleaning Problems We See in Winters Homes
- Tule fog mineral film. From December through February, dense tule fog settles over the valley floor here. It leaves a fine mineral film on panels that cuts winter production by up to 25%. Washing during fog season with the wrong water leaves streaks that harden once the fog lifts. We use deionized water specifically to avoid that.
- Almond and olive harvest dust. Harvest season in Yolo County throws a lot of particulate into the air. Panels near orchards get coated within days. If you clean too early, you’re dirty again by the end of harvest. Timing matters, and we schedule around the local harvest calendar.
- Pigeon nesting under ground-mount arrays. Ground-mount systems on rural parcels in 95694 attract pigeons. Nesting material blocks airflow, droppings etch glass over time, and the wiring under the rails becomes a fire risk. We address the birds after cleaning, not before, so we’re not sealing filth under the array.
- Water intrusion on older roofs. Winters’s downtown Victorians and Craftsman homes have older flashing and eaves. High-pressure spray near those rooflines can force water under flashing and into the 100-amp service panels below. We hand-wash everything, no pressure washing, ever. It’s slower but it’s correct.

FAQs - Solar Panel Cleaning in Winters
How often should solar panels be cleaned in Winters with tule fog and harvest dust?
Twice a year is the right starting point for most Winters homes: once after fog season ends (usually March) and once after the main harvest dust settles (usually late fall). If your array sits next to an almond orchard or a gravel road, you may need a third cleaning. We’ll look at your production data and tell you honestly whether a quarterly plan is worth it. Call (877) 550-6892 and we’ll review your system’s output history with you.
Can cleaning solar panels damage the microinverters or rapid shutdown devices on my Winters roof?
Not if it’s done correctly. We hand-wash with soft brushes and deionized water, and we never pressure-wash or soak the electrical connections. Microinverters and rapid shutdown devices are sealed units, but forcing water at high pressure can breach seals over time. Hand-washing eliminates that risk. Our crew is trained specifically to work around these components without compromising them.
Do I need bird and critter guard installed before or after cleaning my panels in Winters?
After. Always after. If you install guard first, you’re sealing nests, droppings, and debris under the array where they’ll keep causing problems. We clean first, then install guard once the area is dry and clear. That sequence matters more than most people realize, especially on ground-mount systems where pigeons have been roosting for months.
Will cleaning my panels improve my PG&E net metering credits on a Winters agricultural rate?
Yes, and on AG schedules it can be dramatic. Dirty panels suppress production, which means less surplus generation to offset your demand charges. On a farm account with a large ground-mount array, we’ve seen cleaning restore output to within 3% of the pre-soiling baseline. That’s real money on the true-up statement. If you’re on an agricultural rate in 95694, cleaning should be a line item in your annual operating budget, not an afterthought.
Can you clean panels on a metal-roofed ag building or pole-mount array outside Winters city limits?
Yes. We clean metal-roofed ag buildings, pole-mount arrays, and ground-mount systems throughout the rural parcels around Winters, including the areas east toward Russell Boulevard and west toward the orchards. We bring our own water, no connection to your well or irrigation system needed. For larger farm arrays, we’ll quote by panel count and schedule around your harvest and irrigation calendar.
Call Gus’s Solar for Solar Panel Cleaning in Winters
We cleaned a 28-panel ground-mount array off Railroad Avenue for an almond grower whose SolarEdge monitoring showed a 19% production drop after harvest dust settled. Our crew hand-washed each panel with deionized water and soft brushes, then installed critter guard under the rails where pigeons had nested. The next true-up statement showed the farm’s kWh offset back within 3% of the pre-soiling baseline. That’s what we do in Winters. No high-pressure sales, no signature tonight, no vanishing after the paperwork. Gus Petrakis puts his name on the work and answers his own phone, 24/7. Call (877) 550-6892 for a free estimate.
