Leviathan Solar earned near-perfect scores across every category we track, but a pattern in the reviews gave us pause. We found two nearly identical reviews posted one day apart by what appears to be the same customer, both detailing a 22.54 kW system with 49 REC panels and praising salesperson Matthew McAuliffe's responsiveness. That's unusual enough to warrant scrutiny. Setting that aside, the workmanship data is strong. 39 reviewers mentioned flawless installation quality, and inspector Damien's thoroughness stood out in multiple accounts. One homeowner noted he climbed into the attic and onto the roof for a proper assessment while competitors relied on drone flyovers. The crew routed conduit to stay completely hidden on a complicated six-section roof, a level of care that impressed a skeptical customer who'd been researching solar since 2013. We also found a story about Leviathan stepping in to replace faulty equipment from a different installer's botched job, absorbing costs they had no obligation to cover. If you value meticulous installations and don't mind the duplicate-review oddity, the execution quality here is hard to ignore.
If you're weighing quotes and the nearly identical reviews don't bother you, Leviathan delivers clean installs with quality equipment. Just verify that the thoroughness praised in older reviews still holds as the company scales.
Philip Franckel, Esq. spent seven years collecting bids and waiting for panels to improve before committing to a 22.54 kW system — 49 REC panels with Enphase microinverters spread across six roof sections — sized to power his house plus a Cybertruck and a Tesla Model X. He chose Leviathan after comparing multiple quotes: they offered the best price and, crucially, could source REC panels that other companies couldn’t obtain after a REC factory fire. Matt McAuliffe handled his many questions with patience, answering calls and emails promptly, even after hours. Leviathan scheduled the job two weeks after he signed, and the crew completed the installation in 2.5 days; the system was live when they finished seven days ago. The installation team treated his complicated, high-end roof with particular care, routing conduit out of sight and spending extra time so the array is barely noticeable — a result he hadn’t expected but greatly appreciated. The panels performed well immediately, even generating substantial power during an overcast, rainy storm. An inspector visited yesterday and indicated the utility (PSEG) inspector will arrive in a few days. He invites anyone curious to ask Matt (
John discovered a major problem with his home solar system after the original installer refused to accept responsibility. Brandon and Damien from Leviathan Solar stepped in, worked closely with the manufacturer, and arranged replacement of thousands of dollars’ worth of equipment that had failed because of the prior installation. He watched them take over the service contract, handle the negotiations and logistics, and steadily move what felt like a hopeless situation to a resolved system. What set the experience apart was that a company with no obligation to do so took ownership of someone else’s mess, doing the heavy lifting to restore the system and his confidence. He describes the team as patient, honest and reliable, and now has the peace of mind that Leviathan will be the point of contact if anything else comes up — ask for Brandon or Damien.
Jansher chose Leviathan Solar to install an 11.18 kW system on his home and ended up with a smooth installation that wrapped up well ahead of the estimated timeline. He found Matthew McAuliffe refreshingly low-pressure—responsive, patient, and ready to walk him through options so the system fit the house rather than a sales pitch. When other companies pushed cheaper equipment or tried to cash in before the tax credit change, Matthew offered fair pricing, higher-quality components, and straightforward guidance, and stayed accessible throughout the process. The hands-on inspection by Damien really set the job apart: he crawled into the attic, climbed onto the roof, and checked the main electrical panel instead of relying on a quick drone pass. Installers Josh and Travis were professional and respectful, left a very clean site, and routed the conduit so it’s barely noticeable; Josh also fixed a few small issues during the install at no extra charge. The combination of a thorough inspection, careful installation, and met deadlines is what stuck with him after the project.

nornagl’s install began with an engineer crawling through a sweltering attic to inspect the roof and electrical panel — that hands-on, technical first step set the tone for everything that followed. They received a firm quote within a few days with no extra prep required, and the town’s fast permitting left them genuinely surprised by how quickly things moved. Leviathan gave a tight scheduling window: three installers arrived early one afternoon to mount the racks and complete the attic wiring, then came back early the next morning to place all 19 panels and upgrade the electric service. The crew worked quietly and efficiently, stayed polite, and took time to answer questions. Communication stayed smooth through Matt and an office worker who even picked up the deposit to speed the process along. The system is up and running, and the standout detail that stuck with them is how organized and hands-on the planning was — now they’re looking forward to seeing a smaller first bill from PSEG.
Phil had been kicking around the idea of solar since his friend installed panels in January 2013, gathering quotes over seven years as he waited for technology and to grow his electricity needs. He discovered Leviathan Solar on Energysage and chose them because they could actually source REC panels—hard to get at the time after a factory fire—and they gave the best price of the bidders. He ended up with a 22.54 kW system: 49 REC panels spread across all six sections of a complicated, expensive roof, paired with Enphase microinverters. He watched the panels produce impressively even during an overcast, rainy storm, which confirmed why he insisted on REC. Leviathan moved quickly—he signed and the install began two weeks later; the crew finished the physical work in 2.5 days and the system was live when they left, eight days before he wrote the review. Matt McAuliffe handled the sale and follow-up; Matt answered dozens of his calls, returned messages promptly (even after hours), and replied to emails immediately, which kept the long-planned project moving. The installation crew matched that responsiveness with craftsmanship. They routed conduit completely out of sight and took U
Jared Pilkington went ahead with a solar installation on his home and found the entire process smooth and straightforward. He watched the crew complete the install quickly, and more than a year later he hasn’t run into any problems and is seeing substantial reductions on his energy bills. The lasting impression: a fast, low‑hassle install that continues to deliver real monthly savings.
paesana82 went solar in June and discovered the installers completed the whole rooftop system in a single day. They ended up paying less each month even after adding the solar loan to their utility bill, and have been seeing real savings since. The standout detail was how quickly the crew finished the job and how those immediate savings showed up on the first bills—even with the loan factored in.
Matt contracted with Leviathan Solar this past summer to add rooftop solar panels and a battery backup to his home. He discovered the sales director took a lot of time during the design conversations, patiently learning his goals and shaping a system that would meet them despite difficult site conditions. Once crews arrived, installation moved quickly; the team ran into one minor snag and handled it on the spot, resolving it professionally. He ended up with a tailored PV-plus-storage setup that met his objectives — what stood out most was the careful, patient design work that made the rest of the process smooth.

Mike shopped 3–4 companies for a residential solar install and picked Leviathan because they matched product, timeline and price. From the first inspection he found the crew deliberate and unhurried — they listened to his needs, worked around his schedule, and refused to oversell. Rather than pushing a battery, they focused on the right system for his home, used top-tier equipment, and treated him with steady professionalism and courtesy. The team stayed thorough at every stage — sales, inspection, installation and follow-up — so he ended up with a clean, well-executed install and a strong sense that he got his money’s worth. The detail he kept coming back to: no high-pressure upsells (especially on batteries), just careful work tailored to his needs.
Brittany approached Leviathan Solar skeptical — the value felt almost too good to be true, so she arrived with an endless list of questions. The team answered everything patiently and guided her through every step, coordinating a roof replacement, the solar array, and a generator inlet. The crew executed the work with close attention to detail; what she feared would be an eyesore — the conduit — ended up barely visible from the street. The project came together cleanly, leaving her with a new roof and an integrated system that looks like it was always part of the house. What stuck with her most was that affordable price didn’t mean cutting corners: the finished job was tidy and discreet.
