    I had an excellent experience with Leviathan Solar from start to finish. The entire process was handled professionally, and the team made everything easy to understand. A special thank you to Matt, who guided us through every step of the project. He was knowledgeable, responsive, patient, and always available to answer our questions. The installation was completed smoothly, communication was great throughout, and the final result exceeded our expectations. It’s clear that Leviathan Solar takes pride in providing outstanding customer service and quality workmanship. I highly recommend Leviathan

    Amazing service by Matt and the installation crew. Matt made the whole process as easy as can be and designed a system that I am already getting compliments on. The install crew made everything seamless and look very professional. The savings from the system is the icing on top. No more $500+ electric bills and I get to have added home value! Cant recommend anything higher.

    I’ve been with Leviathan Solar since 2022, and the experience has been consistently excellent from day one. What really stands out is how they stay connected even after installation. For example, when I switched internet providers and my system temporarily went offline for monitoring, they reached out right away to help get everything back up and running. That level of follow-through matters. They’ve installed systems not just on my home, but also for my parents and friends, and every single experience has been just as positive. That kind of consistency says a lot about how they operate. Prici

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.

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.
