## The honest read

Invaleon Technologies Corporation, doing business as Invaleon Solar, is a Haverhill, MA solar installer led by Tom Wu, in business since 2011 (the company's own materials elsewhere print a 2010 founding date). It holds an active Massachusetts Home Improvement Contractor license (#182825), verified with the state licensing registry. Google reviewers give the company an aggregate 3.9 stars from 51 ratings, and early customers — installs dating from 2018 through 2023 — often described a smooth, professional sales and installation process with responsive salespeople and on-schedule work.

However, a long and consistent run of one-star reviews from 2023 through 2025 describes a company that becomes very difficult to reach once a system needs warranty service or repair: customers report system failures going unaddressed for months, unanswered calls and emails, and unmet first-year production guarantees. One customer updating an earlier complaint in early 2026 said a system that had been down since November 2025 was not restored until February 2026. A federal OSHA safety record lists five violations and $39,906 in penalties against the company. Court records also show the company named as a defendant in a 2026 construction-related lawsuit, and in an August 2025 Massachusetts bankruptcy court matter the court sustained the company's objection to a claim brought by former customers (the Berkowitzes), based on a prior settlement agreement between the parties.

An earlier Massachusetts HIC license the company once held (#170813) is reported by a directory as having been cancelled at some point — unconfirmed here against the state registry directly. Prospective customers considering a residential installation should also note that at least one recent reviewer said they believed the company had shifted its focus mostly to commercial customers, so it is worth confirming residential service directly before signing on.

**Strengths:**
- Professional early-stage experience — smooth sales and on-schedule installs described in older reviews
- State-verified active HIC license — #182825 confirmed with the Massachusetts registry

**Concerns:**
- Chronic post-install unresponsiveness — recurring 2023-2025 reports of unanswered repair and warranty requests
- OSHA safety record — five violations totaling $39,906 in penalties
- Litigation and bankruptcy court history — a 2026 lawsuit and a 2025 bankruptcy court dispute with former customers

**Where sources disagree:**
- Reported employee count varies widely across sources, from 1 (BBB) to roughly 9-30 (other directories)
- The company's founding year is given as both 2010 and 2011 across its own materials
