Solar Services in Windsor, CA
Windsor sits in one of PG&E’s most frequently shutoff PSPS zones in Sonoma County, and the 2019 Kincade Fire evacuation is still fresh for a lot of families here. That experience changed what “solar” means in this town. It’s not about utility savings first anymore. It’s about whether your fridge, your well pump, and your CPAP machine keep running when the grid goes dark for the third time in a season. Gus Petrakis has been quoting solar in Windsor long enough to know that a panels-only proposal gets a polite “we’ll think about it,” while a solar-plus-battery plan that actually islands your home during a shutoff gets a signature. This page covers every solar service we offer in Windsor, what things cost here, and why backup power is the conversation most Windsor homeowners actually want to have. Call (877) 550-6892 and a live person answers, day or night.

Why Windsor Homeowners Choose Gus’s Solar
Gus Petrakis founded Gus’s Solar in 2011 and has kept his own name on the truck ever since. That matters in Windsor, where homeowners in neighborhoods like Lakewood and the Windsor Oaks area have watched out-of-state crews roll in, knock doors, promise the moon, and vanish after the permit closes. We’re not that company. Gus answers his own phone when he can, quotes real year-25 output off your actual utility bill instead of a brochure number, and tells every person we meet: take two weeks. Think about it. The price will be the same. If a salesman needs an answer tonight, the answer is no. That’s how we’ve earned a strong local reputation in Windsor, and why so many of our calls here start with “I got burned by another company, can you take a look?” We’re licensed, insured, and we send background-checked, uniformed technicians to every job. Dispatch and scheduling are coordinated from our San Francisco Bay Area office, but the crew that shows up to your Windsor home works for Gus, not a subcontractor.
Every solar job we do in Windsor carries the 90-Day Done Right Promise in writing. If it’s not right, Gus makes it right, and one call brings him back. We also offer a Free Second Opinion on Any Written Estimate, a Senior and Veteran 10% discount that never expires, and $40 Off Any Repair Over $200. No trip charge inside our own county, either. If you’ve got a quote from another installer for solar in Windsor, bring it to us. Bring me a bill, I’ll bring you the math.
Solar Services We Offer in Windsor
Solar Panel Installation
We size systems off your actual Sonoma Clean Power bill and Windsor’s real peak sun hours, not a one-size-fits-all template. Most Windsor homes in the 1992-and-newer subdivisions have roofs young enough to support a system without replacement first.

Solar Battery Storage & Backup
This is the service Windsor homeowners ask about most. With PSPS shutoffs a recurring reality, pairing panels with a battery like Tesla Powerwall, Enphase IQ Battery, or FranklinWH aGate means your house keeps running when the neighborhood goes dark.

Solar Panel Cleaning
Windsor’s dry summers mean dust and pollen settle on panels and cut output. We clean systems by hand with deionized water, inspect for damage while we’re up there, and tell you if we see anything that needs attention.

EV Charger Installation
Windsor has seen steady growth in EV ownership, and most homeowners want a Level 2 charger in the garage. We handle the circuit, the panel work, and the charger install so you wake up to a full charge every morning.

Solar Panel Maintenance & Monitoring
We don’t just install and disappear. Gus monitors system performance, and he’s the one who calls you when something drops off. If a panel underperforms, we’ll catch it before you do and schedule a fix.

Solar Panel Repair
Storms, critters, aging inverters, and failed optimizers happen. We repair systems we installed and systems installed by other companies, including plenty of orphaned systems in Windsor from installers who left California.

Commercial Solar Installation
Warehouses, wineries, and commercial buildings in Windsor can offset a serious portion of their load with a properly sized array. We quote commercial jobs off real interval data, not guesses.

Why Windsor’s Climate & Housing Affect Solar
Windsor sits on the Santa Rosa Plain far enough inland to shake off the heavy marine fog that suppresses solar output in Petaluma and Sebastopol. By midmorning, the fog is usually gone, giving Windsor meaningfully higher peak sun hours than the western Sonoma County towns despite sharing the same regional climate label. That means systems here generate more, faster, and the May through October window is consistently strong. On the housing side, Windsor’s residential base was built almost entirely after the town incorporated in 1992, so we’re mostly working with 1990s to 2010s stucco homes on composition shingle roofs. Roofs are typically young enough to avoid replacement before installation, which keeps costs predictable. The bigger consideration is HOA CC&Rs in Windsor’s many planned subdivisions, like Lakewood and the Windsor Oaks area, which can add panel-placement restrictions that slow permitting. We’ve navigated those enough to know what’s coming before it comes.
There’s another piece that most national installers miss when they quote Windsor: Sonoma Clean Power. Windsor falls under SCP as the Community Choice Aggregator rather than standard PG&E generation rates, and that changes how solar export credits are structured and calculated. An installer who quotes NEM payback using default PG&E generation rates without accounting for SCP’s export pricing will hand you ROI numbers that don’t hold up. We build your quote off your actual SCP bill and your actual export rate, because that’s the only honest way to do math for a Windsor homeowner.
Pricing for Solar in Windsor
Solar pricing in Windsor depends on roof size, system capacity, and whether you’re adding storage. Here’s what we typically see:
| Job | Windsor Price Range |
|---|---|
| Panel system only (no battery) | $12,000 - $22,000 |
| Panels plus one battery | $20,000 - $32,000 |
| EV charger install (Level 2) | $900 - $1,800 |
| Panel cleaning (full array) | $200 - $450 |
| Inverter or optimizer replacement | $700 - $2,500 |
These are honest ranges, not lures. We do free estimates, upfront pricing with no signature wanted tonight, and if you’ve got a written quote from another installer, bring it and we’ll give you a Free Second Opinion. Call (877) 550-6892 and we’ll build the math off your actual bill.

FAQs About Solar in Windsor
A panels-plus-battery system in Windsor typically runs $20,000 to $32,000 before tax credits, depending on system size and the battery brand you choose. The battery adds $8,000 to $12,000 on average. Call (877) 550-6892 for an exact quote, and we’ll show you the year-25 output math, not just the day-one brochure number.
Only if you have battery storage with islanding capability. Panels alone shut down during an outage for safety reasons. A properly configured battery like Tesla Powerwall, Enphase IQ Battery, or FranklinWH aGate keeps your essential circuits live when the grid goes down. That’s why backup power is the standard install here, not an add-on.
Windsor falls under Sonoma Clean Power as the Community Choice Aggregator, so your solar export credits follow SCP’s rate structure, not default PG&E generation rates. Any installer quoting payback timelines should be using your actual SCP bill, not a generic PG&E assumption. We build every quote off your real utility statement.
Possibly. Many of Windsor’s planned subdivisions, including Lakewood and the Windsor Oaks area, have HOA CC&Rs that govern panel placement and visibility. California law limits what HOAs can restrict, but the paperwork still takes time. We handle the documentation and know which neighborhoods move fast and which ones don’t.
Usually, yes. Same-day or next-day service is normal for us in Windsor, and a live person answers the phone 24/7 to schedule it. Call (877) 550-6892 and we’ll get you on the board.

What Windsor Customers Say
"Production dropped one spring and I did not even notice. Gus rang me, because he watches the monitoring, and had it sorted the same week."
- Sunita Balakrishnan"My previous solar company went out of business and left me with an array nobody would touch. Gus took the system over, replaced two dead microinverters, and it has run properly since."
- Ferdinand Kaltenbrunner"Four different companies knocked on my door in one summer and every one of them wanted a signature that evening. Gus has a shop with his name on it, gave me the numbers on paper, and told me to take a fortnight and think about it."
- Winifred Castellano
