Typical permits for a solar panel installation in Connecticut: solar/pv permit; electrical permit; structural review (often required). Permit fees in Connecticut typically run 1-3% of project cost. Permits also lock in your inspections — without them, you'll fail any future resale inspection and may face retro-permitting fines.

For a solar panel installation: NABCEP-certified installer; Licensed electrician; Utility interconnection agreement. These specialty licenses (electrician, plumber, HVAC tech) are typically issued at the state level — so even in no-statewide-GC states like Texas or New York, the electrician on your job still needs a state license. DIY risk for this project type: Very high — multi-trade + plan review; almost always pro work.

Visit the official Connecticut license-lookup at https://www.elicense.ct.gov/Lookup/LicenseLookup.aspx and search by name or license number. Verify: (1) license is active, (2) license class matches your project scope, (3) no disciplinary actions or recent complaints, (4) bond + insurance are current. If any of these fail, walk away.
