Smooth experience from start to finish

Best of all is Leviathan's approach to planning the job. The engineer was the first person we met; he crawled through the attic on a terribly hot day, checked our panel, and the condition of the roof. We received a quote within a few days with no extra prep work required. Perhaps we live in a town that is quick to process permits. The turn around was so quick we were stunned. We were given a quick date and time slot. The three installers came early one afternoon and set up the racks and the interior wire connections in the attic. They were here early the next morning to place the 19 panels and work on the electric service. They were quiet, efficient, polite, and happy to answer questions. We had great communication with Matt and the office worker who picked up the deposit to speed the process along. Everything is working well - cannot wait to receive the reduced first bill from PSEG.

Great experience

I got solar panels in June. The whole thing was pretty easy, it was done in one day and I have been saving lots of money. Even adding the solar loan with my bill I pay less than I did without solar. I def recommend.

Leviathan Solar

I found Leviathan Solar by submitting my info to Energysage. I was previously speaking with another company that my friend used for his house. My friend's company couldn't get REC solar panels, which I wanted, and Leviathan gave me a less expensive quote. I have been looking into getting a solar system since my friend got one in Jan 2013. I got quotes in seven of those years. I kept putting off getting a system since 2013 because I was trying to increase my electric usage and wait for the technology to improve. I finally bought a 22.54 kW solar system from Leviathan (49 REC panels on all six sections of my roof), which was installed 8 days ago, two weeks after I signed an agreement. I wanted a system with REC panels and Enphase micro inverters. I’m glad I got REC because it was generating a lot of power during a storm when it was overcast and raining all day. I got a quote from the company my friend used, a quote from another company through Enersage, and one from Leviathan. Leviathan had the best price and was also able to install REC panels. I only wanted REC panels, but they were hard to get because the REC factory had a fire. I spoke with Matthew McAuliffe at Leviathan. Matt was a pleasure to deal with. Matt is very knowledgeable about solar systems and put up with dozens of calls I made with many questions, even after business hours. If I left a message, he always called back immediately. If I sent an email, he always replied immediately. Leviathan’s installation crew was equally impressive. Their crew has been doing installations for many years and is very knowledgeable and clean. They planned the installation to keep the conduit out of sight and spent extra time to route the conduit so it’s 100% out of sight. I have an expensive, complicated roof, and I was initially concerned about the look of the system on my roof, but it’s not very noticeable, and no conduit is visible, so I’m very happy. The installation took 2.5 days, and the system was working when the installation was finished. The inspector was here yesterday and said the PSEG inspector will be here in a few days. I highly recommend Leviathan Solar. If anyone wants to see my system or speak with me, ask Matt for my phone number.

Good experience, Great result

This past summer I contracted with Leviathan Solar to install solar panels and battery backup at my home. During the design/discussion phase prior to the contract their sales director was very helpful and patient, taking the time to understand my goals and making sure I was getting the system I needed to meet those goals given the difficult site conditions. Installation was quick once they arrived on site, with only one minor issue that was resolved quickly and professionally. I can and will recommend Leviathan Solar to anyone thinking about having PV panels installed on their home.

Thoughtful, professional, and a top-tier experience

From the very beginning the crew at Leviathan went above and beyond. They didn't rush the inspection, they didn't try to oversell us, and they worked with our needs. They were kind, courteous, extremely professional, and used top of the line equipment. They did not push for a battery. They worked with our schedule. Every member of the team was truly a pleasure to deal with. We quoted with 3-4 places and Leviathan was the right product, the right timeline, and the right price. I really cannot speak highly enough of them. Fantastic work ethic, extremely thorough throughout the process from sales to inspection, installation, and follow up. I cannot recommend them enough. Give them your business and rest assured you're getting your money's worth.

5 Stars - Excellent Service from Start to Finish!

I recently had solar panels installed by [Company Name], and I couldn’t be happier with the entire process. From the initial consultation to the final installation, their team was professional, knowledgeable, and efficient.
