The percentages are Google’s own arithmetic over every review it holds, not a sample we assembled. Separately we hold 500 review texts for this company, quoted below. Google publishes review ages rather than dates, so every date here is approximate.

    I am writing this review to serve as a direct warning to anyone currently considering Harvest Power for their solar installation. Check my history, I never review anything. Ever. I have been a client of Harvest Power for eight years, hiring them for my initial solar panel installation. I selected them under the assumption that a company with their reputation would maintain at least a baseline level of post-installation support for long-term clients. I was sorely mistaken. Apparently, once Harvest Power collects your initial installation fee, your status as a customer effectively expires. Recen

    Read defined print. This company was great at the start. The salesman sounded great. Turns out, he sold me a system that's too small for my house. Now I have a part that's broken. I was on the assumption that everything is covered for 25 years. But it's not. The labor is not included. So I called a manufacturer and got the part sent to me. That was in november. I'm still trying to get a call back from this company to see what panel is actually out on my roof. The receptionist is amazing. Great people to talk to. Seems to want to help. Past her its a mess. The drawings I have are different from

    Sign contract since November 2025 up to now nothing has been done been reaching out to the company. No one responded back when they finally respond back back in March 25 of 26. He told us he was gonna keep us in the loop for me. this is May 19. Nothing has happened when you calling them. Are they telling you he’s on the phone? He’ll call you back. This company is not a good company. This company is not what you want to be. God forbid something happened to your solar panel no one recurrence calls or reach out to you.

    Mark Lieberman Guided me through the whole process with ease and answered all my questions regardless of how silly they were.After the installation which was done in two days! We saw we could put more panels and he got right on it. Had an answer from mark the following day. Very punctual and organized. His installation team was also very professional. Once again Mark Lieberman thank you for all your assistance and made the whole process seamless.

    We had a great experience with Harvest Power from start to finish. The installers were professional, detail-oriented, and clearly took pride in doing the job right. They were thorough, respectful, and made sure everything was completed properly. We also felt we received a very good price for the system. Our salesperson, Mark Rossini, was especially helpful—he was knowledgeable, well-informed, responsive, and communicative throughout the entire process. He answered our questions, explained everything clearly, and kept us informed every step of the way. Overall, we’re very happy with our experie

    Jason Diblasi was very helpful and informative throughout the process. There was some delay due to inclement weather. As for the service itself, I don't know yet.

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

  • Google also lists this company under electrical.
  • 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 X and Facebook. 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 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.
