    UPDATE TO A PREVIOUS REVIEW: So it's been a year and the owner Corbin hasn't not made good on any promises that he made. He assured me that he would be adding the extra panels to my system at no cost but a few months after that promise asked me to "share the cost". I told him I have already paid enough for the system and reminded him of the promise (I have texts) he made. He agreed and told me it would "be just a few months" but here we are and he's not made good on his promise. I believe it's obvious that he just wanted me to change my review and I naively did because I wanted to believe he w

    Crooks. I was stuck with them as a subcontractor, and they lied repeatedly about problems I have had with bad/wrong equipment. They are unprofessional. They are incompetent and will not reply to your service issues. The final problem was merely over a wrongly installed IQ7 controller that was spec'd to be a $2000 IQ8 controller (out of an $88k system integrated -allegedly- with my home generator). They couldn't even get that done. They took my money and ran, and now appear to be out of business under this name, after a two year back and forth to fix my partially operable system. My attorneys c

    7th update After 2 month later owner Corbin had not responded to set up a date to do upgrade. Solar system is down since 6-21-2024 to 10-4-2024. Gemini solar said it will be finished by November 2024 but no appointment is set up. I would like a communication to be better so I know that I am not falling thru the cracks. 6th update: Tuesday 8-6-2024 Owner Corbin contact me back & explained again that the SolarEdge Invertor is broken & SolarEdge Is "NOT GOING TO HONOR THE MANUFACTURE WARRANTY". SolarEdge requires "Gemini Solar" to replace the broken Invertor to at "Gemini Solar's" Cost. After Tex

    Stellar service, would highly recommend to anyone! Didn't promise me anything they haven't been able to deliver.

    Corbin underpromised and over delivered. I had a lot of consults where people told me solar would eliminate my bill completely. Corbin showed me how everything worked and did not sugar coat anything. I highly recommend this company.

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 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.

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.
