Installer profile

All Energy Solar

Provisional grade. Four of five criteria are verified, including a published 25-year workmanship warranty, which is the longest in our Massachusetts set. The electrician license gap keeps it from an A.

All Energy Solar is a Saint Paul, Minnesota installer founded in 2009 by brothers Michael and Brian Allen, with a Massachusetts operation based in Montgomery. It is BBB A+ rated and accredited with 5 complaints in three years, holds MA HIC registration 175144 per BBB, publishes a 25-year workmanship warranty on all solar installations, and ranked #20 on the 2026 Solar Power World Massachusetts list with 1,864.32 kW installed in 2025. No Massachusetts electrician license number is published anywhere we could find, which matters because solar interconnection work requires one.

Complaints and enforcementVerified

BBB rating A+, accredited since June 2017, 5 complaints in three years with 2 closed in the last 12 months. No lawsuits, regulatory actions, or distress signals surfaced. For a 230-employee company operating residential solar in six states, 5 complaints is a genuinely low number.

Verifiable volumeVerified

Ranked #20 on the 2026 Solar Power World Top Massachusetts Solar Contractors list with 1,864.32 kW installed in MA during 2025, and #130 nationally. Trade press reports 113,000 kW since founding. Its MA volume is modest compared to its national footprint, so ask how many local crews it actually runs here versus subcontracts.

License statusPending verification

MA HIC registration 175144 is listed on the company's BBB profile, issued by the Office of Consumer Affairs and Business Regulations. No Massachusetts electrician license number appears on any page we reviewed, and the HIC alone does not cover electrical work. Ask who holds the electrical license that will be on your permit.

Warranty termsVerified

A 25-year workmanship warranty on all solar installations, published in a dated company announcement. That is the longest published labor coverage in our Massachusetts set and it converts a marketing claim into something you can hold them to. Confirm the 25-year term appears in your actual contract, not just the press release.

How to read this

The 25-year workmanship warranty is the headline here, and unlike most long warranties in this industry it is published, dated, and unconditional on its face rather than buried in a plan tier. The open question is narrow but real: we can find the home improvement registration, not the electrician license, and in Massachusetts the second one is what puts panels on your roof legally. 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.
