If you live on the Tiburon Peninsula and you’re weighing solar, you probably already know the math isn’t as simple as the door-knockers make it sound. A good Tiburon solar estimate starts with your actual PG&E bill, your roof’s orientation toward the Bay, and a straight answer about the marine layer. That’s the kind of estimate Gus Petrakis gives. Call (877) 550-6892 and a live person answers, 24/7, not a voicemail tree.

Why Tiburon Homeowners Choose Gus’s Solar
Homeowners in Tiburon have heard the pitch before. The glossy brochure, the number that changes at the door, the crew that never calls back. Gus’s Solar runs differently. Gus Petrakis founded this company in 2011, puts his own name on the truck, and is the one who picks up when something goes wrong years after the install. We quote the year-25 output, not the day-one brochure number. We tell you to take two weeks before you sign anything. If a salesman needs an answer tonight, the answer is no.
You’ll see our trucks around Paradise Cay, where we’ve cleaned and serviced panels on homes with standing-seam metal roofs that need special mounting hardware, and up in the hills around the Belvedere-Tiburon corridor where Design Review adds a layer of patience to every job. We don’t hand work off to subcontractors. Background-checked, uniformed technicians, and Gus’s own crew does the install.
Solar Services We Offer in Tiburon
Solar Panel Installation
New installations in Tiburon often need split east/west arrays to keep panels off the Bay-facing elevation. We design around the view, not against it. Panels from Qcells, REC, and SunPower, sized to your actual bill, not a square-foot formula.
Learn more about our Solar Panel Installation in Tiburon.
Solar Battery Storage & Backup
Tiburon’s narrow roads and hillside homes mean outages can linger when PG&E crews can’t get a truck up a switchback. A Tiburon Solar Battery Storage & Backup system with FranklinWH or Enphase means your refrigerator and medical equipment keep running, quietly, without a generator rattling the neighborhood.
Learn more about our Solar Battery Storage & Backup in Tiburon.
Solar Panel Cleaning
Marine layer fog leaves a fine film on panels that compounds over the dry season. Tiburon Solar Panel Cleaning every 12 to 18 months can recover production you didn’t know you’d lost. We schedule cleanings around the morning fog so the work happens when the roof is dry.

EV Charger Installation
Teslas and Rivians are common in Tiburon driveways, and a Level 2 charger paired with solar changes the true cost of driving. Our EV Charger Installation - Tiburon service wires chargers to take advantage of your array’s mid-day production, not just the grid.
Solar Panel Maintenance & Monitoring
We monitor system output and call you when a panel underperforms, instead of waiting for you to notice a higher bill. For Tiburon homes with older 2010s-era inverters, we can retrofit monitoring that keeps you informed in real time.
Solar Panel Repair
Microinverter failures, squirrel-chewed wiring, cracked glass from wind-thrown debris off the Bay. We diagnose and repair without pushing a replacement unless the numbers genuinely justify it. $40 off any repair over $200.
Commercial Solar Installation
From the Tiburon ferry plaza area to mixed-use buildings near Main Street, we handle commercial arrays with the same no-hassle pricing and written guarantees we give homeowners.

Why Tiburon’s Climate & Housing Affect Solar
Tiburon’s hillside homes are overwhelmingly oriented toward San Francisco Bay and Angel Island, which means the most valuable roof faces point west or northwest, not south. That single fact changes everything about how a solar array should be designed here. Homeowners often want panels hidden off the Bay-view elevation, but the performing side and the pretty side are rarely the same. We frequently design east/west split arrays, or run a ground-mount feasibility study when the yard allows it, to keep the view clean and the system producing.
Then there’s the fog. Tiburon’s bay-surrounded position means persistent summer marine layer that typically burns off late morning, cutting peak solar hours compared to inland Marin towns like Novato. If a contractor quotes you Novato production numbers for a Tiburon roof, walk away. The housing stock compounds matters: 1960s through 1980s contemporaries and ranch homes terraced into steep hillsides, with multi-pitch rooflines, clay tile, and standing-seam metal that require flashing methods a flat-tract crew won’t know. Before panels, many Tiburon roofs need a reroof, and we coordinate that as one package, so you’re not paying for scaffolding twice.

FAQs About Solar in Tiburon
Tiburon’s Design Review Board can push a permit 4 to 6 weeks longer than a standard Marin County approval. The Board requires panel setbacks from ridge lines and street-facing elevations in many cases. We handle the drawings and the submittal. California’s Solar Rights Act limits outright denial, but it does not remove the review timeline. Call (877) 550-6892 and we’ll tell you what your specific street triggers.
You can, but we usually advise against it. A west or northwest array will produce, just 15 to 25 percent less than a south-facing array over the year. The better play on many Tiburon homes is a split array: panels on the uphill side, clean lines on the view side. Bring us a bill, and we’ll show you the actual production difference in dollars.
Yes, it does. Tiburon’s summer marine layer typically burns off between 10 and 11 a.m., which trims the most productive morning hours. We build fog into our production estimates, and we still design systems that make financial sense here. A generic calculator that assumes full sun from 7 a.m. will overpromise and underdeliver.
Often, yes. Many Tiburon homes from the 1960s to 1980s are at or near the end of their roof life. We can package reroof and solar as one project, which saves money on logistics and means one crew with one warranty. If your roof has 15 years left, install now and plan a remove-and-reinstall down the road. We’ll be honest about which path fits.
Most Tiburon installations land between $18,000 and $45,000 before the federal tax credit. The spread comes down to roof pitch, tile type, and whether you add battery storage. We quote off your actual utility bill, not a square-foot estimate. Take two weeks, think about it, and the price will be the same when you call back.

What Tiburon Customers Say
"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"Honest quoting and good workmanship. He is not the cheapest quote I got, by some way, and he told me that himself and explained what the difference bought. I chose him anyway and I am glad."
- Alistair Fennimore"The install itself was excellent and the system performs as modelled. Permitting and the utility interconnection took about four months, most of it out of his hands, though the waiting was still frustrating."
- Marguerite Ostrowski
