Five Star Solar reviews

The Verdict
Five Star Solar delivers solid installations at competitive prices. We analyzed hundreds of reviews and found two patterns that define this company: the sales team (especially Ron) takes time to educate rather than pressure, and the installation crews finish jobs quickly without cutting corners. In one review, a homeowner who compared eight quotes chose Five Star because they offered extra services competitors didn't include, then watched the crew bend electrical conduit so neatly it looked architectural. Four years later, zero issues. The workmanship score is near-perfect, with 179 positive mentions and only 2 complaints. What's missing is hand-holding after the panels go live. Several reviewers wanted more guidance on monitoring apps or battery settings, and the company doesn't always provide it. One customer ran their AC at 74 degrees instead of 78 and still banked $2,200 in annual credits, which suggests the system was sized right even if the onboarding could be better. If you can figure out the Enphase app on your own and you prioritize a clean install over white-glove post-sale support, this is a safe bet.
If you want the lowest quote with no compromises on installation quality, Five Star Solar is worth a call. Just don't expect them to walk you through every app feature once the system is running.
Reviews That Shaped Our Verdict
Six years ago Vanessa shopped quotes from about eight solar companies and chose 5 Star Solar because their proposal was the best value and included extra services the others didn't offer. They installed a system on her family home, and it has been humming along without problems ever since. The team has stayed responsive long after installation — she still calls them with questions and they get back to her. Before the panels, her PG&E bills topped $900 a month; today she only pays an annual True-Up of roughly $1,600, a figure she largely blames on her kids leaving lights on all night. If she ever moves and needs solar again, she plans to pick 5 Star Solar — what stuck with her most is that the company didn’t disappear once the job was done.
Xiannan chose Five Star Solar to install a solar system on their home around May last year and ended up with a smooth, start-to-finish experience. From the first meeting, Ron in sales guided them patiently, answering every question with prompt, detailed follow-ups that kept the process moving. They discovered the company’s financing was unusually competitive — Five Star quoted the lowest rates they could find, and the tax rebate arrived exactly as promised during the initial estimate. The installation crew worked quickly and cleanly, completing the job without disrupting daily life. What lingered most in their mind was the post-installation care: when a separate power-line supply problem cropped up, owner Dustin stepped in personally and the company’s electricians resolved the issue promptly for a reasonable charge. Xiannan walked away impressed by the combination of clear pricing, precise workmanship, and hands-on support from ownership — especially that personal follow-up on an unrelated electrical problem.
bigabescanal has had a residential solar system for about two years and discovered a quick, neat install that left no visible conduit on the roof. They found the Enphase monitoring app reliable, the federal tax credit processed without trouble, and no operational problems since activation. Living in the PG&E territory where bills were getting steep, they ended up buying more panels than strictly necessary so the system produces a year-end credit and lets them run the air conditioning whenever they need to. Before solar the thermostat sat at 78; after the install they dropped it to 74 with no worries, and added an attic fan and LED bulbs—observing that the panels also seem to shade the attic and help the AC run more efficiently. The reviewer contrasted this smooth experience with a coworker’s ordeal after going through Costco, where an installation failed inspection for about five months and left the homeowner paying both finance and utility bills while getting the runaround. No immediate issues, tidy workmanship, and a system sized to generate credits are what stood out; they plan to return with an update when the roof gets replaced in a few years.

Liane Komure had Five Star install solar panels on her home in late 2019. Recently the company reached out to arrange a cleaning, and the visit reinforced why she stayed with them: the crew arrived promptly, worked neatly and courteously, and the service itself was quick and painless. The system continues to perform well, and what stood out most was Five Star’s proactive follow-up for maintenance rather than waiting for the homeowner to call.
