Invaleon Technologies Corporation

Invaleon Technologies Corporation, trading as Invaleon Solar, is a Haverhill, Massachusetts solar engineering-procurement-construction firm founded, by its own account, in 2011 by Tom Wu, and it holds a Massachusetts Home Improvement Contractor registration, number 182825, that the state registry confirms is active in the company's own name. It designs, installs and maintains photovoltaic systems for homes, businesses and institutions, and its permit record runs to 192 permitted projects. The install experience is where its reviewers are warmest. A 2021 reviewer who interviewed three companies in 2018 credited a salesman who walked them through the loan process, the state incentive program and the expected kWh performance of a 34-panel system without pushing; a 2022 reviewer praised a crew that was "in and out in no time" and an electrical team that concealed conduit on an EV-charger run; a 2023 reviewer chose Invaleon over two rivals on a competitive quote and the fastest start. Its public work is real and documented - the Boston Globe reported in 2022 that Montserrat College of Art hired Haverhill-based Invaleon to install its campus array. Then there is the other half of the record, and it is impossible to miss. Between 2023 and 2025 the company drew a run of detailed one-star reviews with one theme: what happens after the system is energised. A 2025 reviewer whose 23-panel 2018 system failed said a 2022 repair took nine weeks and a later failure went five months with essentially no response; a 2023 reviewer said a battery backup stopped working and repeated notifications produced no call back; another 2023 reviewer said a first-year production guarantee was called a "clerical error" rather than honoured; a February 2024 reviewer said an inverter replacement left production misreporting to the state SREC program and was still unresolved after months. Two structural changes show up inside those accounts, both worth asking about directly. An October 2024 reviewer said Invaleon routed his service call to a third-party company that wanted a new contract with a $300 minimum call-out fee, and a June 2026 reviewer wrote that he believes the company no longer does residential work and is focusing on commercial customers - though in his case they did take the call and organise the fix. There are also public disputes on record: a First Circuit Bankruptcy Appellate Panel case in which the bankruptcy court sustained Invaleon's own objection to a claim, an April 2026 report of an electrical contractor suing New Balance, Green Leaf Construction and Invaleon over $255,000 in unpaid work at a Skowhegan factory, and a public safety-records aggregator listing OSHA inspections with five violations and $39,906 in penalties. The most recent signal is better than the middle years: all three reviews in the last six months are positive, including August 2026 praise for service pursued through a slow warranty vendor and April 2026 praise from a ten-year owner whose large system still outperforms its original estimates. If you are considering Invaleon for a home installation, get in writing who services the system after commissioning, whether that service is in-house or subcontracted and at what call-out fee, and exactly how any production guarantee is measured and paid.
