    Left the country and didnt finish our solar project. Check the news from 2021. We had to pay the sub contractors $6,000 to avoid a lien on our property. We lost less than other customers, beware.

    No longer in business. I had solar installed in 2020, and last month my inverter went out which caused my system to stop working. Their website and Twitter say they "are committed to making sure your system performs as promised" and "customers are being taken care of" as recently as 2/24/24, but my form submissions and 3x followups have gone unanswered since 3/1/24. UPDATE 11/27/24: Still no contact from Sullivan, since 3/1/24. They are actively tweeting that they're still in business - but have comments turned off and are not responding to calls or website form submissions. I'm writing this r

    KICK ROCKS PUNK ! BUNCH OF CROOKS! First these clowns got a lean put on my house because they don't pay their vendors , now my system failed and they are out of business because the owner is a stalker and got convicted and can't have a license to operate. I hope you drop the soap MF ! KICK ROCKS PUNK. Also the address listed on the website is a TACO SHOP! WHAT A LOSER!

    We had then install our solar in 2019 and they were wonderful. We went from having a $300 during the summer to not more than $40. So happy!

    Couldn’t be happier with the service! They were honest, efficient and friendly. And I love the savings, of course.

    Sullivan Solar Power was the 3rd company that I requested a quote from to put solar panels on my condo. From my initial phone call to the post installation orientation , each member of their time was professional, honest, and willing to answer any question. Tyler Boden, the sales representative supported our project every step of the way. James McKnight, the project manager, was also amazing to work with. Their installation crew was respectful and clearly very experienced at what they do. I would most highly recommend Sullivan Solar Panel to anyone wishing to add solar panels to their home

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.

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.

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

Who Google shows alongside them

Google’s own “people also viewed” set, in Google’s order. It is Google’s comparison, not ours.

The ones without a link have no page here, either because Google does not categorise them as solar businesses or because we could not match the name to a listing with confidence.

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 found nothing on a website for this company that states a warranty, a licence or how long it has traded.
  • 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.
