How we rank solar installers in New Haven

Each business is scored on signals we can verify from public data: a live, secure (HTTPS) website, mobile-friendliness, a published phone number and website, and fit with the solar installers category. We do not collect or display customer reviews, and we do not accept payment for placement. Businesses can claim their listing to correct contact details, but the rank is fixed by the data. Owners can claim a listing for a Verified badge and a direct link; sponsors appear only in labeled blocks outside the numbered list. Neither changes rank.

Common questions

Solar Installers in New Haven: quick answers

How are the solar installers in New Haven ranked?

Each listing is scored on public signals we can check ourselves: whether the website is live and secure (HTTPS), whether it works on a phone, whether a phone number and website are published, and how closely the business matches the solar installers category. We do not collect customer reviews, so no star ratings or review counts appear here, and no business pays for placement.

How do I pick the best solar installer in New Haven?

Use this list to shortlist two or three solar installers, then read their Google reviews yourself, confirm license and insurance, and get written estimates before committing. The score here is a filter, not a verdict.

How do I verify a solar installer's license in Connecticut?

Licensing in Connecticut runs through the Connecticut Department of Consumer Protection. Before hiring anyone in New Haven, ask for their Home Improvement Contractor (HIC) registration number and verify it in the DCP eLicense lookup before signing; electricians, plumbers and HVAC technicians hold separate DCP trade licenses. Also confirm current liability insurance, and get the license number in writing on the estimate.

What to look for when hiring a solar installer in New Haven

  • Ask for the PV-1 solar or E-1 electrical contractor license. In Connecticut, solar installers need it from the Connecticut Department of Consumer Protection. Verify it at the official Connecticut license lookup before signing. PV-1 solar licensees cannot connect to your existing electrical panel, so confirm an E-1 licensed electrician will make the panel and grid connection.
  • Written estimates. Any solar installer who won't put the scope in writing is a red flag.
  • Review quality, not just volume. Read the 3-star reviews, they're usually the most honest.
  • Local references. A solar installer who's done work in New Haven will understand local housing stock better than a regional chain.
