Solar in Berkeley should not start with a sales pitch. It should start with your actual PG&E bill, the pitch of your roof, and an honest answer about whether your house is even a good candidate. That is the conversation Gus Petrakis has been having with Berkeley homeowners since he started this company. He will not ask you to sign anything tonight, and he will not quote you a number until he has looked at your roof and your usage. If you want straight answers about solar in Berkeley, call (877) 550-6892 and you will get Gus or one of his crew, not a call center. Our scheduling for Berkeley runs out of our San Francisco Bay Area office, and we know the neighborhoods here well enough to predict what a site survey will find before we park the truck.

Why Berkeley Homeowners Choose Gus’s Solar
Berkeley is not a city where a generic solar pitch works. The homes in the Elmwood and Northbrae neighborhoods are old, the rooflines are complicated, and the homeowners here have been pitched by every door-knocker between the Marina and the hills. What Gus brings is different: a published business address, a license number you can look up, and an owner whose name is on the truck. When a homeowner on Spruce Street calls us, they are calling a locally owned company that has been around since 2011. That matters in a city where plenty of solar companies sell the job, take the deposit, and then outsource the whole thing to a sub they have never met. Gus’s own crew does the install. His own crew flashes every roof penetration. And if something is not right within 90 days, the 90-Day Done Right Promise means Gus comes back and fixes it, in writing.
We hear it all the time from Berkeley customers: they already got burned once by an out-of-state outfit that quoted one price on the phone and a different one at the kitchen table. Our answer is simple. Bring me a bill, I’ll bring you the math. The number we quote off your real PG&E usage is the number you pay. No “good today only” pressure. If a salesman needs an answer tonight, the answer is no. Take two weeks and think about it. The price will be the same.
We work with equipment brands Berkeley homeowners ask for by name, including Panasonic, Canadian Solar, and FranklinWH batteries. And we answer the phone 24/7 with a live person, which is not something you can say about very many solar contractors.
Solar Services We Offer in Berkeley
Solar Panel Installation
Most Berkeley roofs need a little extra thought before panels go up. We model your actual sun exposure, account for marine-layer mornings in the flats, and bid a system that produces what we say it will produce. Learn more about our solar panel installation in Berkeley.
Solar Battery Storage & Backup
Public Safety Power Shutoffs and the general reality of PG&E outages make battery backup a real question for Berkeley homeowners, especially in the hills. We size batteries to your actual critical loads, not a sales chart. Learn more about solar battery storage & backup in Berkeley.
Solar Panel Cleaning
Berkeley’s dry summer dust and eucalyptus debris from the hills settle on panels and quietly shave output. We clean panels without scratching them and check connections while we’re up there. Learn more about solar panel cleaning in Berkeley.
EV Charger Installation
More Berkeley driveways have EVs every year, and a lot of those homes still have the original 100A panel. We can install your charger properly and tell you honestly if a panel upgrade has to happen first.
Solar Panel Maintenance & Monitoring
Gus monitors systems so if a string goes down or a microinverter stops reporting, you hear from us, not the other way around. We keep an eye on your year-25 output, not just the day-one number.
Solar Panel Repair
If you bought solar from a company that is no longer answering the phone, we fix it. We repair undersized, damaged, or badly installed systems on houses all over Berkeley, and we will not tell you to replace a perfectly good array unless it actually makes sense.
Commercial Solar Installation
West Berkeley’s warehouses and light-industrial buildings from 94710 have flat roofs and real usage profiles that support solid commercial arrays. We quote these off actual demand data, and we explain the interconnection process without glossing over how long PG&E actually takes.
Neighborhoods We Serve in Berkeley
Our crews are in Berkeley every week, and we know the difference between a flatlands bungalow and a hillside brown-shingle. That matters for how we plan a site visit and what we expect to find. We typically respond to calls in Berkeley within one business day.

Why Berkeley’s Climate & Housing Affect Solar
Berkeley is a city of two solar climates. The flat western neighborhoods along San Pablo Avenue and down toward the Marina sit under a persistent afternoon marine layer that rolls in off the bay most days between April and August. That cloud band meaningfully reduces annual solar hours compared to a roof just two miles uphill. The same system spec that works on a home near Live Oak Park will produce noticeably different annual output than one near Codornices Park. Any honest Berkeley solar quote has to model that difference. This is why we build every estimate from your address and your usage history, never from a generic regional average.
Then there is the housing stock. Much of Berkeley was built before WWII, and the hillside neighborhoods are densely packed with brown-shingle homes that have steep, multi-pitch rooflines and aging roof decks. The Hayward Fault runs directly through the Berkeley Hills, and the city’s building department routinely requires structural engineering sign-off on a solar permit for homes near the fault trace. That step adds time and paperwork. It is also non-negotiable. We handle it properly and tell you about it before you are surprised by it.
Berkeley also has a municipal tree ordinance that protects many mature oaks, bay laurels, and eucalyptus in the hill neighborhoods. If a beautiful shade tree on your neighbor’s property or yours is blocking the best south-facing slope, you may not be allowed to prune it enough to restore solar exposure. We run a shade analysis early, because we would rather tell you a site does not work than install an underperforming array.
Pricing for Solar in Berkeley
Solar pricing in Berkeley runs higher than the national average for one simple reason: the work is harder. Older homes, steep hillside roofs, seismic engineering requirements, and 100A panel upgrades all push costs up. A modest ground or roof array on a flatlands bungalow might run $12,000 to $18,000 before incentives. A larger system on a hillside brown-shingle with a panel upgrade and structural sign-off often lands between $22,000 and $35,000. Battery storage adds further cost depending on the brand and capacity; FranklinWH and similar whole-home batteries typically add thousands, not hundreds. We quote year-25 production, not a day-one brochure number, and the quote we give is the price you pay. No trip charge inside our own county. Call (877) 550-6892 for a free estimate.

FAQs About Solar in Berkeley
Most Berkeley solar installs fall between $12,000 and $35,000 before incentives, depending on roof complexity, system size, and whether you need a panel upgrade or seismic sign-off. Battery storage adds more. For a precise number built off your actual PG&E bill, call (877) 550-6892 for a free estimate.
Yes. Homes in the Berkeley Hills near the Hayward Fault trace often need structural engineering review before a solar permit is issued. Older homes may also need a main panel upgrade from 100A to 200A before interconnection. We handle the paperwork and tell you what applies to your specific address.
Berkeley ran the first property-assessed clean energy program in the United States, Berkeley FIRST, starting in 2008. That means many Berkeley homeowners are already familiar with PACE financing models and sometimes expect them to be available. We will explain your financing options honestly, including what actually makes sense for your property.
Yes. Gus’s crew works on complex, steep, multi-pitch rooflines regularly. We use proper fall protection and we do not cut corners on flashing or roof penetrations. If your roof needs repair before panels go on, we will tell you rather than install over a failing deck.
Usually not. The afternoon marine layer reduces annual production compared to the hills, but a properly modeled system still saves real money for most West Berkeley homes. We will model your specific address and show you the honest year-25 production estimate before you commit.

What Berkeley 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
