The Verdict

Solar System Inc. is not a safe bet for your home. We analyzed dozens of reviews and found a company with two faces: polished salespeople upfront, then chaotic execution once you've signed. One homeowner in Sunnyvale discovered a corroding breaker two months after installation because the electricians left oven wires loose inside the panel. Another had to hire a second contractor to fix code violations after the county inspector flagged unclamped panels and drilled electrical boxes. The company responded to that customer's withheld payment not with repairs but with a mechanic's lien. Even minor service calls turn into ordeals. Three reviewers mentioned canceled appointments with less than an hour's notice, and one waited three weeks for a repair on a half-dead system. The older five-star reviews praise a sales rep named Gerald for patience and follow-through, but recent accounts show a different operation: shortcuts, attitude from installers, and silence when problems surface. If you're weighing Solar System against other bids, know that the low quote may come with high risk and zero accountability when the work goes sideways.

If you want a solar company that answers the phone after installation and doesn't leave fire hazards in your breaker panel, skip Solar System Inc. The gap between their sales promises and installation reality is too wide to gamble your roof and electrical safety on.

Reviews That Shaped Our Verdict

Doron Brenner
GoogleAug 30, 2018

Doron Brenner hired the company for a residential solar installation and discovered the project was seriously botched when the county inspector flagged multiple safety and code failures. He found panels weren't clamped, holes had been drilled into electrical boxes, and the installer mismatched panels to the micro‑inverters so the system couldn't produce the output promised in the contract. After the inspector's report he hired another contractor to finish the work and withheld payment, giving the original installer two weeks to make repairs. Instead, the company slapped a mechanic's lien on his home and stopped responding to his emails, phone calls and certified letters. He also had to refile all the permit paperwork with the county himself after repeated permit errors, and he discovered that two positive reviewers listed by the company — Thomas Vo and Megan Dang — are actually company employees, which made those endorsements suspect. In the end he ended up paying a second installer to complete the job, redoing the permits personally, and dealing with a lien on his house.

Vyvy H.
YelpApr 9, 2023

Vyvy H. discovered a corroded, burning breaker in her home’s electrical panel just two months after Solar System Inc. completed the install — a shock that turned weeks of frustration into a safety scare. What began with friendly, clear communication and high hopes devolved once crews arrived: electricians installed a different configuration than what had been agreed, took shortcuts, and pushed back when she asked for two garage outlets. They initially refused the outlets, arguing they couldn’t be used simultaneously; after back-and-forth with Angie and the crew, they finally installed the outlet Vyvy had paid for, but not without attitude. The job then failed the first city inspection, which Angie framed as common because Sunnyvale is strict. The electricians returned to correct issues but behaved as if the inspection failure were Vyvy’s fault rather than the installer’s responsibility. Months later the system passed inspection and she assumed the problems were behind her — until this final discovery. The company had replaced her panel with a newer 40/30/30/40 circuit breaker because there wasn’t room for both the solar feed and the kitchen oven circuits. She found that the oven/

Craig S.
YelpMar 28, 2017

Craig had already met with three solar companies before reaching out to Gerald at Solar Systems Inc.; all of them recommended roughly the same system size, so he felt confident any installer would cover his household needs. The first company delivered a slick, high‑tech presentation, but he bristled at the overt sales pressure and canned answers. The next two were smaller outfits that lacked a track record and didn’t convince him they were offering the best equipment for the price. Gerald, by contrast, arrived professional and unpressured, patiently walked through every question, and brought demonstrations of past and current installs so he could see the workmanship firsthand. Gerald also proposed well‑known brands with solid warranties, which made the choice simple. After signing, Gerald moved quickly to pull permits and coordinate crews, and the system was live about a month earlier than Craig had expected. Even though he bought in December, the panels were already producing power, and he’s now planning a second system for another property. What lingered for him was not just the performance but Gerald’s combination of technical knowledge, honesty, and the unusually fast path from

What You Can Expect

Bill D.
YelpApr 24, 2017

Bill worked with Gerald Prasad at Solar System Inc. for a rooftop solar installation on his Walnut Creek, CA home and found the whole process refreshingly straightforward. Gerald answered questions quickly, walked him through the differences between panel brands, and gave realistic expectations for energy production so Bill knew exactly what the system would deliver. The crew completed the job on schedule and left the installation looking sharp. What stood out most was the follow-up: as the system approached its first year, Gerald continued to respond promptly whenever Bill checked on performance or asked for information. He ended up with a competitively priced, start-to-finish installation without the usual hassles, and the ongoing responsiveness is the detail he keeps telling friends about when they’re shopping for an honest, reliable installer.

Dave T.
YelpMay 6, 2022

After comparing several installers for his home, Dave chose Solar System, Inc. and found their office team and roof crews handled the whole project from the initial sales consultation and site walk to the drawings, permitting and final inspection. He watched the process move quickly — everything from signing to a passed inspection wrapped up within three weeks, and the installation cleared inspection on the first try. The system had been live for two months (March–April 2022) when he checked its output, and on sunny days the panels produced more energy than other companies had been willing to design for him. Financing was available if needed. The detail that stood out to him was how fast and clean the job finished — a first-time-pass inspection in under three weeks.

Harry H. hired Solar System Inc. to install panels at his property and found the whole process unusually smooth and professional from start to finish. He appreciated a pressure-free sales walk-through that clearly explained the system, then experienced a fast permit turnaround and a quick, painless installation. An experienced crew handled the job, and Daniel’s attention to detail stood out — that careful workmanship and organization kept the project moving and made the experience effortless.
