Michael & Sun Solar reviews
• last updated FEB 26, 2026Loading map...
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.
Reviews That Shaped Our Verdict
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.
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

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 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.
