    I cannot recommend SonoMarin Solar & Electric after experiencing very unsatisfactory service requiring multiple follow ups. The company installed a generator for me. Subsequently, the carbon monoxide alarm went off inside my house whenever the generator ran for any length of time. A SonoMarin technician said he could see no reason for this. It was later determined by another company that the generator exhaust was being trapped under the front door steps and seeping through vents into the house. I also learned that SonoMarin had never closed out the county permit on their work. When alerted to

    SonoMarin Solar went above and beyond in their installation of solar panels and battery back-up storage. We had gotten royally played by Tesla. When forced to look for alternatives, the two biggest national solar companies tried to strong arm us into letting them become our utility provider. Sounds great up front; but within a few years, we would have been paying them more than PG&E. SonoMarin coordinated seamlessly with our roofing contractor (Equinox Roofing), installed everything as promised and could not have more accommodating and professional. On top of that, they were able to resurrect

    Overall very happy with the team at SonoMarin Solar. Nick was both our salesperson and installer (with a team of course) for a roof stop solar installation in the town of Sonoma. We had an issue on install with a single panel that ended up being dead on arrival, and while it took a bit to get it replaced (supply chain is a mess right now and solar is in huge demand), Nick made multiple trips back to test, replace inverter, and eventually replace the panel. Long story short, you can trust this companies warranty on parts and labor... which matters a lot - especially since the issue I had wasn't

    Top shelf from beginning to end. Sonomarin was the lowest price of 4 bids I received. Local shop that seems very efficient and professional. Nick did a great job explaining how to monitor the system and they color matched the exposed conduit to blend into the house. The system operated perfectly from day one but it’s nice to know that if I ever need to troubleshoot I’ll be able to call Sonomarin and talk to a local honest person to help.

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

  • Established

    “Daabul has been in the solar industry since 2005 and brings with him more than 20…”

  • Years in business

    “of service to our customers. We bring more than 30 years of combined experience to provide you…”

  • Licensed

    “A C-10 (electrical) and C46 (solar) licensed contractor, Avner started his…”

Its website also mentions warranty and licence number, but not in a sentence we can quote cleanly.

Elsewhere

  • It is also reviewed on HomeAdvisor. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.
  • It posts on Facebook and Instagram. A page that stopped posting years ago tells you something a listing will not.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

What we don't know

  • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
  • Google publishes no street address for this company, so we cannot say which town it is based in. Novato is the area its listing was returned for, not an address we hold.
  • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
  • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
