California Solar Group reviews
• last updated FEB 26, 2026Loading map...
The Verdict
California Solar Group delivers solid installations and competitive pricing, but their reliability has slipped. We analyzed dozens of reviews and found a clear split: earlier customers rave about fast installs and attentive service, while recent reviews describe ignored warranty claims and unfinished electrical work. One homeowner waited two months for a city-required panel correction that was never completed, racking up utility bills while the system sat offline. Another reported a malfunctioning panel under warranty with no response from the company. The bright spot is workmanship during installation—11 reviewers praised clean, efficient crews who completed systems in one to two days, and several noted the company handled permitting and utility coordination without friction. Post-install support is the weak link. If you're weighing this installer, know that you may get excellent value and a smooth install, but warranty service is inconsistent. (One customer had to troubleshoot a storage issue on a Sunday and got same-day help. Another has been waiting months. Good luck predicting which experience you'll have.)
If you want a low-cost system installed quickly and don't plan to lean heavily on warranty support, California Solar Group offers competitive value. But if long-term responsiveness matters more than upfront savings, the recent track record suggests you'll want a backup plan.
Reviews That Shaped Our Verdict
Samuel G. remembered the company as dependable when co-founder Danny Thompson ran things, but after Tudor B. returned he found a very different experience. He discovered sloppy record-keeping and a pattern of promises that were later reversed. A panel failed and should be covered by his warranty, yet his requests for a replacement went unanswered. The concrete takeaway: the warranty exists on paper, but months later the faulty panel remains unreplaced and his claim sits unresolved.
Kristineh Y. moved forward with a residential solar installation and then ran into a permit snag: on August 7 the city electrical inspector flagged a correction needed on her electrical panel. She later learned the installer never completed the fix — when she spoke with the inspector a few days ago, he made clear the correction was still undone or had been done incorrectly and suspected the crew didn’t know how to finish the work or coordinate with him. Her calls went unanswered, questions kept getting passed off to other parties on the project, and the job stalled. Two months after the install the system still hasn’t been turned on, leaving her to absorb higher electricity bills while waiting for the company to take responsibility — the most striking detail is that a single unresolved panel correction has kept the whole system offline for months.
Vahan waited a couple of months after CA Solar Group put a residential solar system on his home in November 2021 to be sure everything was working before sharing his experience. He discovered an owner, Armen, who stayed engaged from the start, taking time on the phone to walk him through how the system would perform and why the investment made sense — enough that his initial skepticism evaporated. He found the company's customer service consistently responsive, answering calls and emails quickly and showing deep product knowledge while genuinely focusing on keeping him satisfied. The install impressed him as well: a crew of seven or eight arrived and completed the job in one to two days, professional and efficient throughout. He walked away confident in the system’s performance and plans to refer family and friends to CA Solar Group — a decision anchored by Armen’s hands-on approach and the rapid, clean installation.

Josh W. had solar put on his home 3–4 months ago and ended up with Enphase’s newest I8 system, which he finds excellent. When a utility-side problem arose, the company helped troubleshoot the issue on a Sunday, a level of responsiveness that stood out to him. He found the team highly customer-focused and personable, and their pricing came in very competitive. The financing options also impressed him — aggressive plans with very low rates — and the company recommended a system that matched his needs rather than overselling. What stuck with him most was the combination of practical integrity and after-hours support that made the whole package feel reliable.
David shopped three other bids — including a Sunrun offer with a Costco discount — and discovered CA Solar Group beat them all on price. He hired them and received a fast, tidy installation with financing that felt reasonable. The crew handled the whole job from permitting to the setup of a mobile app that monitors system performance, and they even upgraded his electrical panel. He ended up with a true turnkey outcome: the lowest quote he found paired with clean work and real-time monitoring that he can check anytime.
