    Signed up in September to have solar installed before net metering deadline. They did not respond after the month of November, had to be contacted several times before getting a response. Promised to have installation done but then ghosted. Don't make promises you cannot keep. If you knew September was "too late" then this should've been communicated then and there, instead of wasting people's time and not communicating or providing any timeline either before or after permit approval.

    UPDATE 2: GG is covering our SREC fees as an apology for failing to file our paperwork. Much appreciated. The only satisfactory portion of the process with GreenGrids was the salesman, Michael. Since then it has been an absolute nightmare. Once the sale was done and they got my name on the contract, it has been one failure after the other. Failure 1: They did not get the required documents from the HOA. Once we prompted them multiple times, they finally were able to get what was needed with only a few days to spare before our install date Failure 2: The install. The workers left junk (wires, e

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.

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.

  • Family owned

    “At GreenGrids, we are a trusted, family-owned solar company committed to serving…”

Elsewhere

  • It is also reviewed on Angi 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.
  • It posts on Instagram and Facebook. 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.

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 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.
