Michael & Sun Solar reviews

The Verdict
Michael & Sun Solar earned perfect workmanship scores across dozens of reviews, and we found zero complaints about quality or follow-up. One homeowner watched the owner and his crew discuss their installation plan on-site before starting work, and said it built confidence in a way no contract could. Another praised the team for diagnosing why a 7.2kW system only produced 6.1kW at peak (turns out the system uses some of its own power, good to know). We noticed 30 reviews singling out the craftsmanship and 19 specifically mentioning post-installation support without a single negative among them. The company stands out in two areas. First, they educate rather than upsell. Five reviewers mentioned Michael & Sun was the only installer to request a full year of electric bills before sizing the system, ensuring you don't overpay for capacity you'll never use. Second, they troubleshoot connection problems themselves instead of punting to the utility. When one customer hit a snag going online, the team walked them through every hiccup until the system worked. If you want the cheapest quote in Sonoma County, keep shopping. But if you want a local crew that will show up when your inverter throws an error two years later, this is the team.
If you value a local installer who'll still answer the phone when something breaks after the warranty clock starts ticking, Michael & Sun Solar is worth the premium over a volume contractor.
3 Stories That Stood Out
Dave L. rarely writes reviews, but after a smooth install of a 28-panel, 11 kW PV system on his shop roof he felt compelled to share the experience. He encountered a highly organized team from the start: Matt, the design engineer, walked him through clear trade-offs and even pointed out that trimming nearby trees would boost energy harvest — detail that helped them make sensible choices for their site. Once they signed the proposal, project manager William took charge of scheduling and the PGE interaction, keeping communication steady even though the start date was months out. The crew surprised him by beginning earlier than planned: materials arrived on day one, and on day two installers Brett and Sean showed up with owner Michael and William. He watched the group map out the plan together and then move efficiently into action. In two days they finished the rooftop layout and roof- and attic-side wiring, leaving the interior wiring neatly routed and the panels looking well integrated on the shop roof. The system passed inspection a few days later; utility permission took a little longer, but the array has been on the grid for about two weeks and is performing right in lineกับt
Fred-Rick hired Michael & Sun Solar to outfit his home with a rooftop system. The crew guided him through panel selection, handled outreach and permitting, and carried out the installation smoothly—no glitches during the work. After activation he noticed the system’s peak showing 6.1 while the design had been for 7.2; the installers walked him through the reason, explaining that the system itself uses some of the energy it produces, which clarified the gap. He also received helpful follow-up support whenever questions arose. One year later the array has produced a small net surplus, and what stuck with him most was the combination of clean installation, quality equipment, and the clear, patient explanations that followed.
GreenGrl approached the project with a high bar—her sweetheart is an electrical/HVAC contractor who demands clean, careful work. Because of that scrutiny they chose Michael&Sun Solar for the team’s professionalism and attention to detail, especially after the company insisted on reviewing a full year of electric bills to correctly size the system—the only installer who asked for that. During the design phase and site survey the crew stayed organized, courteous and methodical, which built confidence. Two months after activation they logged almost no electricity draw from PG&E. Even if Michael&Sun came in a touch higher on price, she felt their tight-knit team and that thorough sizing process were what made the system perform, and she would hand them another house’s keys without hesitation.

Lou hired Michael and Sun's to install an Enphase solar system with a battery backup two years ago, then brought them back last year to add panels after he bought an electric vehicle. He found their work consistently professional and reliable — they handled permits, installation, and follow-up without fuss and stood behind the equipment they installed. When questions or problems popped up, they answered quickly; if an issue couldn't be fixed over the phone, they showed up at his door rather than leaving him stranded. Because of that responsiveness he re-engaged them without hesitation, and he still calls them first whenever a system question comes up.
Steve watched Michael’s team install two separate sections of solar on the house and ended up with the kind of straightforward experience homeowners hope for: solid workmanship and no surprises. The crew handled the job with care, delivered an excellent-quality install, and kept every promise about what would be done and when it would happen. The standout detail was the follow-through — they simply did what they said they would, right on schedule.
A year after his 2024 rooftop solar install from Michael & Sun, Walt discovered the system has been running flawlessly. He watched his PGE bill shrink to just a few hundred dollars a year, a dramatic change from before. Michael & Sun handled the installation and all the permits, staying helpful through the process. He ended up with 24 panels on the roof — more than it looks at first glance, but necessary to keep an electric car charged — and the panel count is the detail that made the biggest difference to his energy bills.
Debora F. had Michael & Sun install solar panels on her home two years ago. The crew finished the entire installation in a single day, and the process felt seamless from start to finish. For the past two years she’s enjoyed steady power production from the system and appreciated Michael & Sun’s attentive customer service. What sticks with her is the one-day install paired with reliable output over two years.
Steve D hired the company to install solar on his 100‑year‑old house and ended up impressed by the crew. Michael and Matt completed a quick, neat install and handled the heavy permit and PG&E paperwork without drama. The one blemish was a miscommunication about the microinverter model: he would have chosen the next model up if he’d been properly informed, so he docked a star. As a retired electrical contractor who’s hard to please, he’s sparing with five‑star ratings, but he would use the company again. The memorable takeaways: solid workmanship and strong permit support—just confirm inverter model selection before signoff.
David came to Michael & Sun Solar after two friends pointed him their way, and after comparing three bids he settled on them for a year-end project that had to stay on schedule. What stood out most was how closely the team listened: they took in both his immediate needs and what he might want later, then kept refining the proposal with him until it fit. Throughout the process, the crew stayed easy to reach, answering questions quickly before the panels went up and even after installation when concerns came up. The work wrapped exactly on time, which mattered with his tight deadline, and William and Michael left a strong impression with the way they handled the job.
Sue and her household ended up with a solar installation that felt like a strong fit from start to finish, both in the product support and in the price they paid. The standout for her was how smoothly the whole experience came together, leaving them feeling genuinely happy with the system on their home.
Tammy was picky and compared pricing and product from several vendors before she chose Michael & Sun for a solar-plus-backup install on her rural property. From the first meeting through final hookup, she watched the team operate like a well‑tuned operation staffed by genuinely friendly people — communication stayed clear, schedules held, and the crew delivered exactly what they promised with no surprises. The installation finished in December 2024, and she’s since reaped the benefits of solar generation plus a backup system: outages that used to cause anxiety now pass without her flinching. The detail that mattered most to her was that the backup power actually works when the grid fails — a practical outcome that made the whole comparison-shopping effort worthwhile.
