A house built before 1980 has electrical bones from a different era of energy use — a panel sized for a window air conditioner and a handful of lamps, not a solar array, a battery, and an EV charger. That’s the East Bay’s housing stock in a sentence, and it’s exactly the kind of project Sun First Solar has been designing around since 1984. We install residential solar and battery storage throughout Alameda County and the East Bay, from Oakland to Livermore, working out of the Bay Area for over four decades. If you’re ready to talk through what a system looks like on your roof and your panel, call 415-458-5870.
Solar and battery storage for East Bay homes
Sun First Solar sells solar panels and battery storage as one project, not two separate sales conversations. When we design a system for an Oakland or Berkeley home, the battery — usually a Tesla Powerwall — gets sized alongside the panels from day one, because that’s how the numbers and the daily use actually work together. Most of our residential clients see a 5 to 7 year payback on the full system, backed by a 25-year manufacturer warranty on the panels themselves.
That combination matters more here than it does in a lot of the Bay Area, and not for abstract reasons. The East Bay’s grid has specific stress points — aging infrastructure in older neighborhoods and a hillside fire risk that occasionally shuts the power off on purpose. A solar-plus-battery system built correctly doesn’t just lower your bill; it keeps your lights, fridge, and medical equipment running when the grid can’t. We’ll cover exactly why below.

Why East Bay homeowners choose Sun First Solar
Sun First Solar has been family-owned and locally operated since 1984, which puts us among the longest-running solar installers serving Northern California. That matters most in the fine print: every installation is performed by our own employees, never subcontracted out to a crew we didn’t train and don’t manage. It’s a slower way to grow a solar company, and it’s why we carry an A+ rating with the Better Business Bureau.
Our approach is consultative rather than transactional — we design each system around your roof, your electrical panel, and your actual usage rather than pushing a standard package. That includes making sure you understand every incentive you qualify for, including the 30% federal tax credit currently available on a full solar and battery installation. Questions about how any of this applies to your home are easiest to answer over the phone — call 415-458-5870.
Built for East Bay conditions
Oakland’s housing stock is old by California standards: roughly three out of every four housing units in the city were built before 1980, according to Census Bureau data. Homes from that era were wired for a much lighter electrical load than a modern solar-and-battery system asks for, which is why our process starts with a full panel and electrical review rather than assuming your existing service can take the new equipment. It’s a step some lower-cost installers skip, and it’s the difference between a system that works cleanly for 25 years and one that trips a breaker the first time you run the dryer and charge a car at once.
The financial case has gotten sharper, too. PG&E’s average bundled residential rate sits around 39.25 cents per kWh as of early 2026, among the highest in the country, which is what makes a well-sized solar system pay for itself as quickly as it does here.
Then there’s the reason a battery isn’t optional in this county the way it might be elsewhere: large parts of the East Bay hills carry a Very High Fire Hazard Severity Zone designation under Cal Fire’s current maps, and homes in those zones see Public Safety Power Shutoffs during dry, windy conditions. A battery paired with solar keeps your home running through those shutoffs instead of leaving you in the dark until PG&E gives the all-clear. Alameda County residents also get their electricity through Ava Community Energy, the county’s community choice provider — worth knowing as you plan a system that works alongside your existing utility setup.
