New England Clean Energy is a solar installer headquartered in Hudson, MA with a Bedford, NH office, founded by Mark Durrenberger and installing solar systems since 2006 (the company added heat pumps to its offerings in 2017, per its own site). A regional business-journal item describes the company's expansion into southern New Hampshire under Durrenberger. Reviewers across several years describe a consistent process: a full in-person home evaluation before any quote, clear explanation of options, and clean, efficient installations. One 2023 reviewer said other companies they'd considered skipped the in-home evaluation the company did as standard practice; another described a one-day install where the crew redesigned the panel layout to cover more of the roof than originally planned. Multiple reviewers, including one on the Better Business Bureau's own page, describe larger battery-backed systems — a 20kWh dual-array setup with REC panels, Enphase inverters, and a FranklinWH home battery — completed to their satisfaction. The company also gets praised for standing behind work beyond the original install: one reviewer whose system was installed by someone else specifically hired New England Clean Energy just to manage and service it, calling the price fair and the team a pleasure to work with. Another BBB reviewer described working with the company since 2007 across multiple solar projects and a battery back-up installation — a long relationship that speaks to more than a single good experience. Nothing in the reviews here raises a concern; every account on file, spanning 2022 through 2025, is positive. For a solar installation or battery back-up project in southern New Hampshire, the reviews describe a company that takes the time to evaluate a home properly before quoting and follows through with careful, clean installation work.
“Hudson-based New England Clean Energy, which designs and installs solar energy products for homes and businesses, has expanded into southern New Hampshire, its president Mark Durrenberger, announced Thursday.”
NECE installed a large dual array system using REC panels, Enphase inverters and a FranklinWH home backup. The entire process was amazing. Highly recommended integrator.
Very professional, responsive, kind and a pleasure to work with. Very fairly priced. You did not install my solar, but I'm so happy I found you to manage my system.
Our experience with New England Clean Energy was excellent from start to finish. Their 5 step process was very helpful in defining what to expect from them and what is expected from us. Our first contact was with one of their Sales Consultants and he did a great job helping us understand the size of the system, the equipment that would be installed, what we could expect in the way of system performance, and, of course, the cost and benefits. The engineering step is focused on system layout, locations of panels and the materials that will be needed. The operations step covered permitting with local authorities, material ordering and the creation of the project installation schedule. The installation step involved the on-site construction of the system, the inspection by local authorities leading up to this issuance of the Certificate of Completion. In the final step, the utility company installed a new meter and we were given permission to operate the system. This entire process took about 3 months. The group that we had the most exposure to was the installation team. The lead person was extremely personable, knowledgeable, and accommodating. The other crew members were also very respectful of our property and left the site clean and tidy. All in all, the crew was hard-working. I don't think they ever took a break the whole time they were here. I have no hesitation in recommending New England Clean Energy to people thinking about going solar.
They installed our solar array in one day, neatly, cleanly and efficiently. Pricing was reasonable and they managed to cover almost our entire roof with panels. They even redesigned the layout--there were originally going to be two vertical rows and three horizontal; now they're all horizontal--when they re-measured the roof. Our roof isn't visible to a lot of neighbors, but this aesthetic improvement was much appreciated. They have also kept us updated as the process went on. Now we're just waiting for Eversource to hook us up! NECE is great--Eversource is frustrating.
Going solar had been on our mind for a long time and so we did quite a bid of legwork ahead of time. We considered a few local companies, but finally settled with NE Clean Energy and never regretted it. Their service has been outstanding in every way. All of our questions were always answered quickly and thoroughly. They took care of everything and got our system up and running in record time. All the people we got to interact with were super nice and caring. Even with a lot of grey and rainy days since the beginning of the spring, we have seen our electric bills drop drastically! And with the tax break, we expect to recover our initial investment even faster than anticipated. Great job NE Clean Energy and thank you.
