Its one and two star share is 6 points above the typical installer in the Lowell area. Across Massachusetts, 60 of the 198 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 5 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

    Do not go with this solar company. They charge you an outrageous fee for everything. The final straw was when they charged me $1500 when I sold my property. They said that is what it cost to transfer the ownership of the solar panels from me to the buyers of my property. Absolutely ridiculous.

    During the whole process from the initial assessment and quote to the completion of the installation of our solar system Ace Solar and their teams provided an excellent service, they have been extremely professional, very thorough and very pleasant to work with. Their installation was very clean, smooth and on time. I was very impressed with how their teams work together in harmony, their schedules very well synchronized and everything was completed on a timely basis as promised. Upon the final inspection the inspectors were impressed and commended their clean and thorough work. My project con

    The entire team at ACE Solar has been a pleasure to work with. My salesperson Sam Willis contacted me via EnergySage when I was shopping around for a solar installer. Sam was responsive, knowledgeable and never pushed me towards anything I didn't want. Sam worked with me to update the proposal to include more panels and switch to a microinverter solution. I signed the contract at the end of January 2023, had my site visit about four weeks later, and the panels were installed mid-April 2023. The install crew finished the entire job in less than a day and was absolutely phenomenal - they were pr

    Very satisfied with the installation and performance of the system. System output actually exceeds my expectations. Ace Solar has followed through with all all contracted requirements. I would use again without hesitation.

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.

  • Licensed

    “your bottom line. Construction Our licensed electrical teams leverage modern…”

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

Elsewhere

  • It is also reviewed on 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.
  • It posts on Facebook, LinkedIn, YouTube, Instagram and X. 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.
  • 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.
