Its one and two star share is 15 points above the typical installer in the Portland area. Across Maine, 6 of the 43 installers whose breakdown Google has published carry a higher share than this one.

The percentages are Google’s own arithmetic over every review it holds, not a sample we assembled. Separately we hold 6 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

Each mark is one company we hold in the Portland area whose Google breakdown has been read, placed by its share of one and two star reviews. Greenworx Energy is the red one. The amber line is the middle of that set, which includes suppliers and maintenance businesses as well as installers.

    Greenworx installed an extensive system at our home. The installation went fine and after some tweaking the system worked well. Unfortunately, Greenworx post installation service is atrocious. They have missed scheduled appointments with no calls, and are now completely unresponsive. We are left with no choice but to call a different company to fix Greenworx’s issue. Beware that you are rolling the dice with this company.

    I had a partial installation of my solar panel project. After trying to get the installer to finish the project for well over a year, I gave up and started looking for a new installer. When Quinn heard about my predicament he went out of his way to come to my house much sooner than was scheduled. Being the owner, he was able to sit down and write up a new contract on the spot. I asked him to make some changes that very day and he did. He gave me time to look over the contract carefully and to take my time deciding. After looking over the contract I asked for more changes to make the contract c

    Greenworx Energy delivered an A+ solar panel solution for our home. From the start Mike gave us a straight forward plan, Quinn provided great engineering detail and Mark/crew executed the installation precisely as the design called for in a single day. Very professional from start to finish, ensured complete functionality and got us up/running with RI Energy quickly. Multiple follow ups since completion. The provided Mobile App provides energy production details every 15 minutes, comparisons to previous day/week/months. Highly recommend.

    Anyone who is interested in a high quality job with no hassle and an owner who is attentive and precise needs to call Quinn Allen @ Greenworx Energy, he takes the time to answer all questions. The Installers that Greenworx have, pay attention to detail and go beyond your expectations to ensure you are happy. I recommend this company they will not let you down.

Reviewer names are not published here. Negative reviews are shown first because they are the ones a listing hides, not because they are more representative.

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 and the Better Business Bureau. 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.
