Finding a Solar Company You Can Actually Trust in Connecticut

Connecticut Has Great Solar Companies — and Some Terrible Ones

With over 106,830 solar installations completed and roughly 10.7% of Connecticut homes already running on solar, the Constitution State has a mature solar market. That maturity brings real benefits — experienced local installers who know Eversource and United Illuminating interconnection processes inside and out. But it has also attracted bad actors who see Connecticut's high electricity rates (4th highest in the nation at 27-32 cents/kWh) as an opportunity to make aggressive promises to homeowners desperate for relief.

The Connecticut Department of Consumer Protection (DCP) has taken enforcement action against multiple solar companies in recent years. Vision Solar received a $5 million judgment for fraud. Solar Wolf was hit with a court order blocking them from doing business in Connecticut entirely. And SunRun — one of the largest national solar companies — was sued by the Connecticut Attorney General for deceptive sales practices. These are not isolated incidents. They are the ones that made the news. Your best defense is knowing how to verify any company before signing.

How to Verify a Solar Company in Connecticut

Connecticut requires two licenses for any company installing solar on residential homes: a PV-1 license (specifically for photovoltaic installations) and a Home Improvement Contractor (HIC) license — both issued by the Connecticut Department of Consumer Protection (DCP). This is not optional. You can verify any contractor's licenses at the official CT DCP license lookup tool online. Check that both licenses are active, note the license numbers, and confirm the business name matches who you are dealing with. If a company cannot produce both license numbers on the spot, walk away.

Beyond licensing, look for NABCEP-certified installers — this certification is required for eligibility under Connecticut's RRES rebate program. Ask how long the company has been installing solar specifically in Connecticut and whether they have experience with both Eversource and United Illuminating territories. The interconnection process is different for each utility, and an installer unfamiliar with your utility's requirements can add weeks to your timeline. A company that has navigated permits in Stamford's coastal zone is not necessarily prepared for Hartford's historic district requirements, and vice versa.

Red Flags That Should Send You Running

Connecticut's enforcement record reads like a cautionary tale. Vision Solar racked up a $5 million judgment for fraud — they were making promises they could not keep and leaving homeowners stuck with underperforming systems. Solar Wolf was blocked from operating in Connecticut entirely by court order. SunRun, one of the biggest names in national solar, was sued by the Connecticut Attorney General for deceptive sales practices targeting Connecticut homeowners. If major companies can cut corners, smaller ones certainly can too.

Watch out for any company that pressures you to sign today with a "limited-time offer" — the RRES program and CT Green Bank Smart-E Loan are not disappearing overnight. Be wary of salespeople who promise to eliminate your Eversource or United Illuminating bill without seeing it first. Scrutinize any contract with rate escalators buried in the fine print, and never sign a 20-year lease without fully understanding the terms. If something feels off, verify licenses through the CT Department of Consumer Protection or file a complaint with the Connecticut Attorney General's office.
