Green Power Installers delivers clean installations at competitive prices, and the owner personally fixes problems when they happen. We found 17 mentions of workmanship quality, with reviewers singling out clean roof penetrations and reliable system performance. One homeowner hired them twice over four years, the second time doubling system capacity to 9.7kW, and reported a three-day turnkey install with EnPhase microinverters running smoothly from day one. Reviews show Barukh responds to equipment failures quickly (one customer got same-day panel repair) and personally handles configuration questions, making it easy to choose inverters and monitoring setups. In one case, an employee dropped the ball on follow-up communication, the owner found out, and he sent a handwritten apology plus corrective action. If you're willing to do some homework upfront on solar basics, you'll get straightforward pricing and an installer who shows up when things go wrong.
If you want an installer who'll send a crew the next day when a panel stops working, and an owner who writes apology letters when an employee messes up, Green Power Installers is a solid bet. Just arrive with basic solar knowledge, because they focus on execution over beginner education.
Hari A. picked GPI for a rooftop solar install on his Bay Area home after the team walked him through multiple panel, inverter and mounting options so he could choose what suited him best. He compared bids from other installers and found GPI’s pricing among the most reasonable in the area. When one panel stopped producing, Barukh dispatched a crew the next day to diagnose and repair it. Hari wanted panel-level monitoring, and Barukh arranged an Envoy unit to provide that visibility. A year after installation, changing the Wi‑Fi on the Envoy required a different app — Barukh personally stopped by and reconfigured everything himself. The memorable detail that still stands out: the owner’s hands-on follow-up, including an in-person visit a year later, made the service feel ongoing rather than finished at handoff.
When Yaron moved into a new home four years after his first install, he called Green Power Installers again — and they lived up to his expectations. He found their pricing to be the fairest in the area, encountered professional staff and crews, and watched owner Baruch deliver on his promises. This time they doubled the system capacity to 9.7KWH and placed EnPhase microinverters under each panel. The crew completed the turnkey install in three days, the monitoring immediately began reporting daily generation, and the household started saving on its monthly bills. He also referred friends who ended up very satisfied, and he’s happy to be contacted as a referral himself. What stuck with him most was the three-day, turnkey turnaround that produced visible daily generation right away.
Antonio X. encountered a communication breakdown after his solar install and discovered the problem traced back to one of the company’s employees. He had been handling the back-and-forth exclusively with that staffer, even though during the actual installation he had enjoyed steady direct contact with Barukh. When Barukh learned what happened, he reached out personally, expressed genuine surprise, and apologized—handing over a handwritten letter and taking additional corrective steps behind the scenes. Antonio offered blunt, constructive criticism about how the situation unfolded; Barukh listened, accepted the feedback, and committed to adjusting internal procedures so the same mistake won’t repeat. What mattered most to Antonio was that GPI’s owner didn’t shrug it off: he owned the issue and remedied it, leaving Antonio satisfied enough that he’ll contact Barukh directly in the future and remains happy with GPI.

Chris experienced a problem with his home's solar panels and backup batteries, and Swell Energy sent technician Barukh to resolve it. Barukh quickly diagnosed and corrected the issue, then patiently answered every question Chris had. What stood out was Barukh's blend of technical know-how and friendly, clear communication—Chris rewarded that combination with his highest recommendation for both Barukh and Swell Energy.
G W. chose GPI about a year ago for a roughly 6 kW system with 22 panels and discovered the array is still performing reliably. During the shopping phase they didn’t get as much beginner education or detailed shading and production analysis as other vendors offered, but they ended up with the best-value proposal — good-quality equipment and a scheduling window that fit their timeline. GPI moved quickly through the whole process, so they needed to stay on top of decisions and provide timely, specific instructions. A few minor installation issues popped up, but GPI corrected them promptly. After the first year the system met expectations. The clearest takeaway: learn the solar basics before your meeting and be prepared to keep pace with GPI’s fast timeline to get the most from their value and responsiveness.
Ramamurthy hired Greensolar to install solar at his Cupertino home and discovered the team delivered professional, high-quality work much faster than he expected. After trying other installers who dragged their feet just to get the project started, he ended up with Greensolar finishing the job in record time without cutting corners. He walked away impressed that speed and workmanship came together — the quick, tidy completion is what he remembers most.
Donald hired Green Power Installers to add a Tesla Powerwall battery to his home’s existing solar system. He found their work fantastic, ended up with the battery incorporated into his setup without issue, and walks away impressed — he highly recommends them for Powerwall add-ons to an existing array.
Miguel S. chose Green Power Installers to fit an 8.9 kW rooftop solar array on his home, along with a new main panel and a 240V EV charging line. From the first phone call through the site consultation, installation and post-install follow-up, the company treated the project with a steady focus on customer service. Barukh stood out: Barukh patiently answered technical questions, laid out options clearly, and led a crew that worked efficiently and courteously on the roof. An engineer by trade and very particular, he pressed for detail and found the team's communication and technical expertise matched the high Yelp praise he'd read. He received cheaper bids, but chose to pay a bit more because Barukh’s patience and engineering knowledge removed uncertainty. When the work finished, he ended up with a cleanly installed 8.9 kW system, an upgraded main panel, a functioning 240V EV line and clear post-install support. What stuck with him most was that Barukh walked him through the engineering details until he felt comfortable — the deciding factor against lower-priced offers.
Viktor chose Green Power Installers to put a roof-mounted 5.12 kW PV system on his home, and the crew wrapped up the installation today. He followed a referral to installer Barukh from a friend who had a system installed just a couple of weeks earlier, and that recommendation proved decisive. The install went smoothly: the team worked efficiently, stayed professional, and was easy to coordinate with. Viktor ended up with a finished rooftop system that he describes as excellent workmanship delivered at a very reasonable price — the quick referral and solid execution are what stood out most.
Keith M. chose Green Power Installers for a rooftop solar setup on his home and walked away impressed by Barukh and the crew’s mix of friendliness and efficiency. He found them responsive to questions and willing to offer practical input during the process. When an inverter initially failed to register in the Enphase monitoring system, the team corrected it the same day and it showed up in the portal that evening. They also paid attention to appearance — color‑matching all exterior conduits and routing them where he wanted to keep them out of view from the street — and cleaned up thoroughly after the job. He ended up comfortable enough to use them again and to recommend them to friends and family; what stuck with him most was how neatly the conduits blended with his house.
