Golden Bear Solar reviews

The Verdict
Golden Bear Solar handles expansions and battery add-ons well, but stumbles on follow-through. We analyzed reviews spanning five years and found a small team led by Mike Thompson that knows Enphase gear inside and out. One Palo Alto homeowner praised Mike for navigating the city's famously complicated permitting process without breaking stride, while another hired him to fix mistakes left by a previous installer and watched him diagnose the problem in minutes. Reviews show 19 mentions of solid workmanship and 22 mentions of smooth project execution, most tied to system expansions where the crew matched existing panels and cleaned up sloppy wiring from earlier contractors. But three reviews detail the flip side. One customer paid an extra $8,000 to fix problems created by a Golden Bear referral and got no help when they asked the company to intervene. Another called repeatedly for required maintenance and was ignored. The company earns high marks when Mike or Jack is on-site, but responsiveness falls off a cliff once the install wraps.
If you need a battery retrofit or a panel expansion on an existing system, Golden Bear's technical chops make them a solid pick. Just don't expect much support after the crew packs up.
3 Stories That Stood Out
Karthik chose Golden Bear Solar and Mike Thompson to install a 10 kW solar PV system with a 20 kWh Enphase battery on his Palo Alto home. From first contact through final installation, Mike kept the process straightforward and moved things along efficiently. He and Jack showed up as confident, knowledgeable, and easy to deal with, handling system design, deployment and the city approval process — a notable feat given Palo Alto’s tricky permitting rules. The project felt like a rescue: Karthik had already worked abortively with three other vendors (one of which went bankrupt after taking his deposit), and Golden Bear finished what the others couldn’t. The outcome: a fully installed, city-approved 10 kW PV array paired with a 20 kWh Enphase battery — and the clear sense that the team could navigate tough local rules when others failed.
Rick L. ended up with a poorly performing solar system and non-working batteries after another company’s install, spending months wrestling with persistent problems. Local installers pointed him to Rob at Golden Bear, who showed up quickly to perform an audit, discovered a range of installation errors, and began fixing them right away. Rob not only repaired the system and restored the batteries to working order but also produced a professional, itemized report documenting the original installers’ mistakes. He ended up doing far more work than the initial quote implied yet honored that original price, saving Rick both time and future electrical costs. The detail that sticks: Rob’s rapid, thorough audit plus a formal error report — and no surprise charges — turned months of frustration into a resolved system.
Clay H. pursued Golden Bear Solar for a solar project and accepted the company’s referral to install a replacement heating/AC unit — a decision that turned costly and dangerous. He discovered after the HVAC job finished that the outside condenser had been mounted so close to the house it would slash its expected life from about 20 years to roughly six, the attic unit installed was the wrong model (heating only, no air conditioning), and a makeshift control panel and wiring run through the attic and interior walls created a clear safety and code violation. By the time those problems showed up, he had already paid the installer in full. He turned to Mike and Rod at Golden Bear Solar to help resolve the mess with their referral; they refused, pointing out there was no contract with them, and then stopped returning calls and emails. Clay — whose wife works frequently with subcontractors and thought the company ought to at least help undo a bad referral — had to hire another contractor and pay about $8,000 to correct the errors and install the proper unit. The detail that stuck hardest: the unsafe, out-of-code wiring and a surprise $8,000 repair bill after taking a recommendation from a

What You Can Expect
Neha B. hired the crew to install Enphase batteries and the related equipment at her house. Dee coordinated the project from the office while Mike and Jack handled the on-site work, texting to nail down scheduling and working through the install efficiently and professionally. They treated aesthetics as part of the job, choosing code-compliant mounting locations that also looked tidy and symmetrical. After the install, Mike returned to walk her through each component and the monitoring app, explaining everything clearly so she felt confident using the system. The blend of technical competence, steady communication, and attention to how the hardware looked left her impressed — she would call them back, particularly for that neat, code-compliant installation and the thorough app walkthrough.
Subroto started hunting for a battery to pair with his home solar array and first ran into a friend who warned, "solar is a scam," a caution that felt true after two disappointing conversations with other contractors. Finding Golden Bear — a local installer in Los Gatos — changed the tone. Mike stepped in with clear competence and technical knowledge, while Jack and Dee backed that up with authenticity and steady follow-through. The team put him at the center of the process: they listened to his needs, configured a tailored battery solution, met the scheduled milestones, and then walked him through the completed system so he understood how everything worked. What lingered for him was the combination of neighborhood proximity, predictable scheduling, and a final, thorough explanation — the elements that turned a skeptical search into confidence in the installation.
Sabina needed a solar system on a house with a Spanish tile roof — a tricky inset installation — and ended up working with Mike, Jack, Pedro and Dee. They guided her through design, installation and the paperwork maze, handling city and PGE approvals and securing permission to operate. The crew fitted 22 PV panels and an Enphase setup, including four of the new 5 kW batteries, and the system has been performing beautifully. The detail that stands out: they successfully executed the complicated tile inset and took care of all the permitting, leaving her with a fully commissioned, battery-backed Enphase system.
When Jesse Jones needed his solar array taken down and put back up so roofers could redo his roof, he hit a wall: the original installer declined the work and other companies gave shockingly high estimates for what was essentially a small removal-and-reinstall. He found Golden Bear willing to step in. They provided a clear, reasonable quote, worked their schedule around the roofing crew, and carried out the job with a clean, professional crew. What stood out was their flexibility and transparent pricing on a job that other firms treated as inconvenient — that practical, hassle-free approach is what he walked away remembering.
Karthik chose Golden Bear Solar and Mike Thompson to install a 10 kW solar PV system with a 20 kWh Enphase battery on his Palo Alto home. From first contact through final installation, Mike kept the process straightforward and moved things along efficiently. He and Jack showed up as confident, knowledgeable, and easy to deal with, handling system design, deployment and the city approval process — a notable feat given Palo Alto’s tricky permitting rules. The project felt like a rescue: Karthik had already worked abortively with three other vendors (one of which went bankrupt after taking his deposit), and Golden Bear finished what the others couldn’t. The outcome: a fully installed, city-approved 10 kW PV array paired with a 20 kWh Enphase battery — and the clear sense that the team could navigate tough local rules when others failed.
Mike hired the company for a residential installation of Enphase panels, batteries and switchgear and experienced smooth service before, during and after the work. He found the installation team consistently responsive at every step, answering questions and staying engaged through completion. The crew’s attention and follow-up produced results that went beyond his expectations. The memorable takeaway: a fully installed Enphase system backed by a team that stayed on top of the job from the first call through final checks.
Marina L. turned to Golden Bear Solar after a colleague’s strong recommendation and worked directly with Mike Thompson to design a system for her home in Saratoga. She chose REC panels paired with an Enphase battery and accepted a very competitive bid; Golden Bear also handled the PG&E paperwork so she qualified under NEM2. The crew completed the installation in three days, making the process feel seamless with professional, knowledgeable, and helpful technicians on site. At the final Saratoga building inspection, the inspector complimented the quality of the work — a detail that stayed with her and underscored the care the team put into the project.
Allen arranged for Golden Bear to reinstall his solar batteries after the replacement units arrived. They detoured from another job and showed up in about 30 minutes, installed the new batteries, and tracked down and fixed several serious problems left by the original installer. The crew walked him through each step as they worked, removed the old batteries, and left him with a system that actually functions — the quick arrival and the team’s thorough repairs were the standout parts of the visit.
Steve D. hired the company for a rooftop solar install and discovered the crew had actually mounted the panels backwards. He found their initial cost and savings estimates were far off, and after a year his utility bills hadn’t improved — he felt he would be better off without the system given the follow-up service. The founder left the company about a year in, which left him wishing he’d gone with a well-known, name-brand installer instead. When he raised problems, the team offered excuses rather than fixes; he judged Mike and his crew inexperienced and suspected the company’s five-star ratings were propped up by friends. The detail that sticks: a botched physical installation combined with inflated promises left him paying more and chasing answers.
