Installer profile

Nexamp

N/A
Not graded. Nexamp develops, builds, and operates community solar farms and sells subscriptions to their output. It does not install rooftop systems on homes, and its Massachusetts home improvement registration lapsed in 2012. An installer grade would describe a product it does not sell.

Nexamp is not a rooftop solar installer, so this page assigns no grade. It is a community solar developer and operator headquartered at 101 Summer St in Boston, with a second headquarters in Chicago. The product it sells to households is a subscription to a share of a solar farm built somewhere else, credited against the subscriber's utility bill. Its about page pitches an "average of $275 annual electricity savings" for subscribers and describes itself as "One party for financing, construction, and customer management." Nowhere on that page, or on its solar development page, does it offer to put panels on your roof. If you searched for a Boston installer and found Nexamp, you found a different product category.

Judged as what it is, Nexamp is big. Solar Power World's 2026 list ranks it 35th nationally on 245,711.53 kilowatts installed in 2025 and classifies it as a Developer whose primary market is community solar. On the Massachusetts list it ranks 11th on 4,147.00 kilowatts. The company says two U.S. Army veterans founded it in 2007, and BBB shows incorporation on November 16, 2007, 18 years in business, 180 employees, and the alternate names Nexamp, Inc. and Nexamp Solar, LLC. Zaid Ashai is Chairman and CEO; Will Thompson is Co-Founder and SVP of asset management.

The state registry settles the installer question. Nexamp, Inc. held Massachusetts HIC registration 166723, effective June 28, 2010 and expired June 27, 2012, listed to responsible person Dwight Thompson at a North Andover address. It has not been renewed. A company that had the consumer home improvement lane and let it lapse more than a decade ago is telling you it does not contract with homeowners for work on their houses. That is consistent with the business model, not a discipline finding. Nothing in ePLACE surfaced an electrician license under the Nexamp name, though that lookup was mid migration. An aggregator lists a license number 16175 for Nexamp; it was not verified against any state registry and we do not repeat it as fact.

The complaint picture is what a homeowner considering a subscription should actually weigh. BBB rates Nexamp A+ and has accredited it since February 13, 2019, but the profile shows 133 complaints in the last three years and 34 closed in the last 12 months. There are 106 BBB customer reviews, and the one star reviews reference the community solar program and solar credits, meaning billing and credit timing, not installation workmanship. The Google rating of 3.9 across 240 votes likely reflects the same subscription experience. No government enforcement action, attorney general case, or consumer protection matter against Nexamp was found. The one federal case in the research, Nexamp, Inc. v. Consolidated Edison, Inc. et al in the Southern District of New York, had Nexamp as plaintiff against two utilities; the court dismissed Nexamp's claims with prejudice on March 25, 2025. It is a commercial dispute, not a mark against the company's conduct toward customers.

The evidence

LongevityVerified

Nexamp says it was founded in 2007 by two U.S. Army veterans. BBB shows the business started January 9, 2008 and incorporated November 16, 2007 as a corporation, 18 years in business, with 180 employees. The company and third party dates agree within months, which is rare enough to note.

Complaints and enforcementVerified

BBB shows 133 complaints in the last three years and 34 closed in the last 12 months against an A+ rating and accreditation since February 13, 2019. One star reviews reference the community solar program and solar credits. No government enforcement, attorney general action, or consumer protection case against Nexamp was found in searches run September 25, 2026. The only litigation found was a commercial suit Nexamp brought against Consolidated Edison and Orange and Rockland Utilities, dismissed with prejudice on March 25, 2025.

Verifiable volumeVerified

Solar Power World's 2026 national list ranks Nexamp 35th on 245,711.53 kW installed in 2025, headquartered in Massachusetts, primary service Developer, primary market community solar. The 2026 Massachusetts list ranks it 11th on 4,147.00 kW in the state. This is utility and community scale development volume, not a count of residential rooftops.

License statusAdverse record

Massachusetts HIC registration 166723 for NEXAMP, INC. is Expired: effective June 28, 2010, expired June 27, 2012, responsible person Dwight Thompson, 21 High St Suite 209, North Andover. It has not been renewed, so Nexamp holds no active Massachusetts consumer home improvement registration. No Construction Supervisor qualifying individual is published for residential work, and the ePLACE electrician lookup returned no results during the eLIPSE migration window. An aggregator license number 16175 is unverified. The lapse fits a company that does not contract with homeowners, but it is an adverse fact for anyone treating Nexamp as a rooftop contractor.

Warranty termsPending verification

No rooftop workmanship warranty is published because Nexamp offers no rooftop installation product. Its about page describes subscription savings and a single party for financing, construction, and customer management. A subscriber's protections live in the subscription agreement, not in a construction warranty, and that agreement was not part of this research.

How to read this

No grade is a description, not a verdict. Our rubric measures whether a contractor will build a system on your roof and stand behind it, and Nexamp does not do that. If you want panels on your house, cross this name off and keep looking. If you are weighing a community solar subscription, the useful evidence on this page is the complaint volume and what the complaints are about: credits and billing. Read the subscription agreement for how credits are calculated, when they post, and how you cancel, then compare that to the 133 complaints before you sign. Our full rubric, including how our own installation business gets graded on the same scale, is on the methodology page. We are a solar installer and we partner with other solar companies. Grading is structurally separated from revenue; see disclosures.
