Best Solar Installers

East Bay

Fidelity Roof delivers solid work with unusually strong follow-up. We found 14 reviews praising their post-installation support, including one homeowner who's called them back multiple times over three years for free gutter checks and minor roof inspections, always getting same-day or next-day servi

Source Energy is a safe bet if you want a hands-on broker who'll stick around after the sale. We analyzed dozens of reviews and found one name popping up in nearly every story: Andres, the broker who apparently answers calls months after installation and explains your system performance without corp

Bene Electric is a solid, straightforward choice for homeowners who want an electrician they can trust. We analyzed customer feedback and found Cole Bene stands out for two reasons: his diagnostic skill and his willingness to solve your problem over the phone if he can. One homeowner described a fiv

Williams Electric solves the problems other electricians can't. We analyzed hundreds of reviews and found the same pattern over and over: customers tried one or two contractors first, got nowhere, then called Geoff Williams and had power restored within hours. In one case, two warranty-approved elec

GRID Alternatives isn't your typical solar installer. They're a nonprofit that trains volunteers and job seekers to install panels on low-income homes at no cost to the homeowner. We analyzed hundreds of reviews and found the model delivers real results. One homeowner in San Diego paid zero out of p

Sky Power Solar is a safe bet if you want a local installer who'll still be answering your emails in five years. We analyzed nearly a hundred reviews and found two recurring patterns: crews who complete installations on schedule without drama, and a monitoring system that catches panel failures befo

Suntrek Solar has been around long enough to build a loyal base, especially for pool heating. One homeowner came back to them after 13 years because the first install never leaked; another said their pool finally became usable after three summers of sitting empty. We noticed 196 reviewers praised th

American Array delivers dependable solar installations at competitive prices. We analyzed their portfolio and found consistent execution on the fundamentals: installations that meet city and utility approvals on the first try, systems producing at or above estimates years later, and warranty repairs

Sierra Roofing and Solar is a reliable pick for combined roof and solar work. We analyzed hundreds of reviews and found the company excels at managing complicated dual projects, the kind where a crew tears off your old roof, installs new shingles, and then puts your solar array back on without damag

All On Electric runs into trouble when something goes wrong. We found a homeowner whose inverter failed in February 2022 but wasn't replaced until June, costing her $849 in extra utility charges because the company never explained she could monitor the system herself. When she asked for reimbursemen

HCI Solar has a serious telemarketing problem. Two reviewers allege the company uses shell names like Solar America and ZeroDownSolar to repeatedly call people on the federal Do Not Call list, even after being asked to stop. One reviewer dug into the company's business filings and found inconsistenc

Solar Sesame can deliver a working solar system, but the path from contract to power-on is littered with avoidable problems. In one Hayward install, panels went up fast, then the battery hookup dragged six months because the crew installed gear in the wrong spot (failed inspection), scheduled inspec

Lamorinda Solar divides customers into two camps. We found 13 reviewers praising Mark's installation workmanship, citing crisp coordination with roofers and systems still running strong after 10 or even 18 years. One homeowner had a leak fixed within 48 hours of calling, another watched their pool j

This company has left multiple customers with broken systems and unfulfilled promises. One homeowner paid a deposit for Tesla batteries, waited two years, received defective units from a defunct manufacturer instead, endured six months of troubleshooting, then watched those batteries fail entirely.

Diablo Solar has a long track record in the Bay Area, but our analysis found a troubling split. We reviewed hundreds of customer accounts and discovered a stark pattern: long-time customers who paid for annual maintenance calls praised the company, while those who needed ad-hoc service or callback o

Alcor Solar Specialists has kept some Bay Area pools warm for decades, but recent service has gone sideways. We found 15 longtime customers who praised owner Al and his team for responsive repairs and honest advice over 20-plus years, often returning for second installs. But we also saw a pattern of

Skytech Solar looked like a solid pick for years, but recent reviews reveal a company struggling to stay afloat. One homeowner watched 30 percent of their system go offline two years after installation; Skytech argued about warranty coverage for weeks before finally sending a tech who fixed it in mi

Bay Valley delivers solid roofing work but struggles with consistency. We found 127 reviewers praising their workmanship, yet the follow-through can be frustratingly uneven. One homeowner waited through 8 phone calls for a leak quote that never arrived, only to get callbacks immediately when he dial

Sun Light & Power has loyal repeat customers, but we found enough breakdowns to warrant caution. One homeowner described how the company ghosted them after installation, forcing them to call Sun Light & Power for rescue when their original installer vanished, and a technician named Devon not only fi

Simply Solar has a split personality that should give you pause. We analyzed reviews spanning nearly a decade and found a company that delivers clean installs and attentive communication when things go right, but stumbles badly when problems arise. 187 reviewers praised the workmanship itself, insta

SESCO handles complex electrical work well, but scheduling problems crop up often enough to make us wary. In one review, a homeowner took time off work for a 9 a.m. panel inspection, only to receive an email at 5 p.m. the night before saying the electrician couldn't make it and suggesting she call c

Semper Solaris leaves too many customers stranded when systems fail. We found over 200 reviews describing the same pattern: months-long delays for basic repairs, project managers who vanish mid-job, and warranties that turn out to be meaningless when you actually need help. One homeowner paid $55,00

Yorkshire Roofing is not worth the risk. One apartment manager watched crews blindly shoot thousands of screws into a flat roof, shorting electrical for 22 units, then got stuck with a 50% cost overrun when the owner refused accountability and threatened to abandon the half-finished job. Another hom

SolarXperts will leave you paying two bills at once. We analyzed over a hundred reviews and found a pattern: smooth sales process, fast installation, then silence. One homeowner waited 10 weeks with panels installed but not turned on, paying both PG&E and the solar loan every month while the company

West Coast Solar's customer service has collapsed since their earlier years. Reviews from 2017-2020 describe prompt installations, responsive reps, and attentive follow-up. But newer reviews tell a different story: one homeowner waited three months just to get a response about underperforming panels
