Sun's Free Solar reviews

The Verdict
Sun's Free Solar delivers uncommonly clean work for a fair price. We analyzed dozens of reviews spanning EV charger and solar installations and couldn't find a single complaint about follow-up support. Thirty reviewers specifically praised the crew's workmanship, including one competing installer who showed up after Sun's Free finished the electrical portion and said, 'I'd hire them again.' Kevin and his team handle tricky jobs others won't bid on, like routing charger wiring through basements to avoid exterior eyesores or upgrading 1955 electrical panels to support custom battery setups with Sol-Ark inverters. Fifteen reviews mentioned speed and professionalism during installs that included all permits and inspections. Fourteen emphasized responsive communication and quotes that came in $500 to $1,000 below competitors. Seven praised Kevin's troubleshooting expertise, fixing improper prior installs and optimizing charging setups that passed inspection on the first try. One homeowner ran completely off-grid for three weeks while waiting for PG&E approval, batteries rarely dipping below 30 percent overnight and recharging by mid-morning.
If you want cookie-cutter solar from a household name, look elsewhere. But if you're installing a custom battery system or need an electrician who'll route charger wiring through your basement to keep it hidden, Sun's Free will bid the job and finish it right.
Reviews That Shaped Our Verdict
Y'shua had a Tesla home charger installed a couple of years earlier, but the setup turned out to be wrong. He and his wife rely on a single charging station for two electric cars, so slow charging on days they both need to top up became a real hassle. They called Kevin, an easygoing technician who arrived quickly, figured out the installation problem, and reconfigured the unit. After Kevin's fix, both cars charge noticeably faster from that one station — the concrete change that made busy days manageable and stuck with him as the memorable part of the visit.
Barry needed a 240V outlet in his garage for an EV charger — a job that turned out to be more complex than a simple outlet swap because it required a new electrical panel and running wire from the back of the house to the front. Kevin Good and his crew threaded the cable through the maze of the basement, taking extra care to keep the run out of sight and produce a tidy, aesthetically pleasing result. They worked meticulously and wrapped the entire installation in one day. Their bid came in $500–$1,000 lower than other electricians, so he walked away with a neat, professional installation completed quickly and at a noticeably better price.
Kelly J. wanted to outfit the San Rafael house she bought last year with a substantial solar-plus-battery setup and discovered the project was far from a cookie‑cutter job. They ran into a major code-driven complication: the original 1955, 100‑amp main panel was maxed out and had to be upgraded to a 200‑amp panel — and current rules required the service and panel to be moved to the exterior of the house. The closest practical spot for the new exterior service was only about two feet away, on a narrow wall that might challenge PG&E approval, but keeping the panel there also meant the batteries could stay in the garage where milder temperatures would likely extend their life instead of mounting them on a sun‑baked exterior wall. Having installed a system a decade earlier, Kelly decided she didn’t want the high-priced, cookie‑cutter options many local firms push. She chose two well‑reviewed EG4 batteries (to get over 25 kWh of backup at roughly half the per‑kWh cost of market leaders) and a Sol‑Ark 15k inverter, but found most installers either refused to bid or stuck to the usual brands. After a long search she contracted with American Array, but after two months of little progress

What You Can Expect
Scott W. worked with Suns Free Solar on two projects over the past few years and gave them a five-star review. He found the crews consistently friendly and appreciated that they took the time to explain exactly what they were doing — a relief for someone not familiar with solar — and the installations themselves were solid. He ended up with quality workmanship and clear communication, and liked the experience enough that he hopes to hire them again. The detail that stuck with him was their patience in walking him through the process, which turned a confusing topic into something he felt comfortable pursuing more of.
Mark has relied on Kevin and his team for about ten years to handle solar on his home; they put a 42-panel array on his roof that dramatically cut his electric bill. Over the decade Kevin kept improving the system — he recently upgraded the microinverters and is now installing two Tesla batteries that will charge from the rooftop panels. Mark walked away impressed by Kevin’s fairness, dependability and hands-on follow-through: prices stayed reasonable, problems got fixed, and Kevin stood by the work. The detail that lingers is the long-term relationship and ongoing upgrades — initial installation plus sustained maintenance and battery expansion — that turned a one-time job into a continuing, reliable solar setup.
Fast chose Sun's Free to put a solar system on his Alameda home about a year and a half ago, and ever since the panels flipped on he hasn't received an electric bill. After factoring in Alameda city rebates and available tax credits, he found the price made sense and moved forward. During the install Kevin kept showing up on site to check progress and make sure every detail went in cleanly, and Fast appreciated that the crew explained the whole process in plain, easy-to-follow language. Sun's Free handled all the city paperwork, so communication stayed simple — Fast only dealt with Kevin and Sheldon, and he found Sheldon to be excellent as well. Beyond the technical work, the company’s community ties stood out: Sun's Free maintains close involvement with youth development and gives back locally. For Fast the two takeaways are clear — a flawless installation and 18 months with no electricity bill — details that made the decision feel worthwhile.
