iSP Solar (Ion Solar Pros)
Get one thing straight before reading anything else about this company. Ion Solar Pros LLC of Middlebury, Connecticut is not ION Solar, LLC of Orem, Utah. The Utah company has 320 BBB complaints in the last 3 years and its own set of federal lawsuits. The Connecticut company has 1 complaint in 3 years, zero closed in the last 12 months, and an A+ BBB rating with accreditation since May 2021. Review sites and complaint aggregators mix these two up constantly. Check the entity before you trust anything you read.
On the license side, Connecticut runs contractor credentials through its eLicense system, and the pattern here is a company-level Home Improvement Contractor registration paired with an individual electrical license. iSP holds HIC.0660303, active through March 31, 2027, and its qualifying electrical credential is John Mancini Jr, ELC.0203061-E1, an active Electrical Unlimited Contractor license that permits all electrical work under section 20-330 of the general statutes. The state search row for that license carries the DBA ION SOLAR PROS LLC, so the tie is on the state record, not just the company website. No PV-1 or PV-2 limited solar contractor license and no company-level E-2 appeared in any search, which is worth knowing but is not unusual; an E-1 covers more than the PV licenses do. The company also holds an active registration as an apprenticeship sponsor for an Electrician E-2 program, which suggests it actually trains electrical labor rather than just renting it.
Two things keep this at a B. First, volume. Neither the 2026 Solar Power World national table nor the 22-row Connecticut table contains an iSP entry, so the claim of in-house W-2 crews covering all 169 Connecticut towns rests entirely on the company's own pages. Second, the warranty. There is no published in-house workmanship term at all. What iSP publishes is a 30 year Solar Insure warranty on qualifying cash and loan systems, third-party backed, covering parts, labor, diagnostics, battery replacement, and installer failure protection by its own description. Qualifying is the word to interrogate. One more oddity: the company's own pages date its founding to 2012 in one place and 2017 in another, while BBB records the business start and incorporation as December 11, 2014. None of that is disqualifying. It just means the paperwork should do the talking when you get a quote.
The evidence
BBB dates the business start and incorporation to December 11, 2014, which makes the company roughly 11 years old, but iSP's own pages conflict with that and with each other: the about page title says since 2012, the page body says founded by Bill Barrieau in 2017, and the Connecticut page badge says since 2017. The BBB date is the anchor; the site dates are marketing.

BBB rates the company A+, accredited since May 10, 2021, with 1 complaint in the last 3 years and 0 closed in the last 12 months, and states no government actions. Searches for enforcement surfaced Connecticut AG actions against other solar companies and federal suits naming ION Solar, LLC of Utah, a different company; nothing found names Ion Solar Pros.

Neither the populated 2026 Solar Power World national list of 388 contractors nor the 22-row Connecticut list contains an iSP or Ion Solar Pros entry, so no independently published megawatt or project figure exists. The claim that in-house W-2 crews cover all 169 Connecticut towns is first-party only.

No in-house workmanship warranty duration appears on the fetched home, about, or Connecticut pages. The published warranty is third-party backed: a 30 year Solar Insure warranty on select PowerHouse systems, described on the Connecticut page as available on qualifying cash and loan systems and covering parts, labor, diagnostics, battery replacement, and installer failure protection. Confirm in writing that your system qualifies.

How to read this
This grade leans on state records and a quiet complaint file, not on the 4.9 star listing rating. It cannot verify how many systems iSP actually installs, because no third-party volume figure exists, and it cannot tell you whether your specific system qualifies for the Solar Insure coverage. So ask for both: recent comparable installs in your town, and the warranty qualification in the contract itself. And if you research this company yourself, keep the Utah ION Solar's record out of your notes, because it belongs to someone else. 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.
