    All I state is the the truth. All Bay Solar won't admit and fix issues. Instead, blaming on customer. I trusted he said he was able to do various of work. It looks like each job has problem. Since Carlos doesn't take responsibilty to fix the issues, I had to hire others to fix his work. It ends up cost more. He installed generator, electric panels at my home, electric meters for apartment and laundry have problems. Only electric charger was good job. The laundry installation cost over $11k and took 8-9 months to finish it with lots of obstacles. Both I and electric inspector asked Carlos to so

    I chose All Bay for my solar installation (solar system, house battery, EV car charging circuit installation) among a handful of competitors. They were great to work with, discussed with me whether I was a good candidate for solar, what a right-sized system looked like, managed all the communication with PG&E including minimizing complications associated with relocation of equipment. They inspected my roof, did high quality work, and even went above and beyond on a couple efforts I asked about. I would choose them again and may consider them for non-solar work. Minus half a star as they were s

    We hired All Bay Solar to redo our roof — including new skylights and gutters and tiles — and install a complete solar panel and battery system, along with a full re-fit of our home's power distribution and electrical panels. The owner, …

    The folks at All Bay Solar (Especially the owner Carlos and the project leader Edgar) did both my roof and my solar installation. After the solar was installed, it was underproducing and I contacted them and explained my concern. They came on site several times, tweaking the strings and making sure the system was working as efficiently as expected. I know I can trust that All Bay will take good care of my roof and solar installation for years to come and that to me was worth the money. You can get cheaper quotes online through energysage or whatever but for the 5% you might save you'll get stu

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.

  • Free estimate

    “conducting a detailed, accurate and free inspection of your property and evaluating your…”

  • Years in business

    “engineers and technicians have more than 25 years of experience combined in the solar…”

  • Licensed

    “for your solar project? All Bay is a licensed General Contractor and electrician…”

Its website also mentions insured, but not in a sentence we can quote cleanly.

Elsewhere

  • It is also reviewed on Yelp. 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, LinkedIn and X. A page that stopped posting years ago tells you something a listing will not.

As Google published them when we last read the listing, not a live check. Ring before you drive anywhere.

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.
  • 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.
