Home solar in Connecticut

Net metering Replaced by a lower credit

Classic net metering closed at the end of 2021. Since January 2022 home solar uses the Residential Renewable Energy Solutions (RRES) program with two choices: 'Buy-All' (the utility buys all output at a fixed rate) or 'Netting' (your output offsets your use, with a per-kWh charge on solar output plus an incentive payment). PURA sets new rates each year for that year's enrollees. Public Act 26-127 extends the programs through 2035; new tariffs under the extension start January 1, 2028. Source

• 2022-01: RRES replaces net metering
• 2026-10-28: PURA approves 2027 netting charges (3.25 cents/kWh Eversource, 6.57 cents/kWh UI; 4.02 cents/kWh for both in 2026)
• 2028-01-01: successor tariffs under Public Act 26-127 begin; spending caps for solar-only systems
• 2035-12-31: extended programs end

Solar credits (SRECs) Limited

There is no open SREC market for homes. Under RRES, the utility takes your renewable credits in exchange for the tariff payment. Source

Taxes

Property tax: exempt - residential Class I renewable systems such as solar are exempt from local property tax (C.G.S. 12-81(57))
Sales tax: exempt - solar electric systems are exempt from sales tax (C.G.S. 12-412(117)) Source

Solar laws

• Public Act 26-127 (HB 5340) - renewable energy affordability and access (2026). Extends residential, commercial and community solar programs through 2035, with cost caps from 2028 (solar plus battery systems exempt if PURA finds net benefit), automated solar permitting, and rules for small plug-in solar.

• Public Act 22-25 (SB 4, Connecticut Clean Air Act) - HOA solar (2022). Common interest communities may not stop an owner from putting solar on their own roof if it is not shared with another unit; associations may set size and installation rules. Source

Community solar

Available but small: the Shared Clean Energy Facility (SCEF) program offers subscriptions mainly for low- and moderate-income customers, and is extended through 2035.

Federal tax credits

The 30% federal tax credit for homeowners who buy solar (Section 25D) ended for systems placed in service after December 31, 2025, so buying no longer earns a federal credit. If you lease or sign a power purchase agreement (PPA), the panels belong to a company that may still claim a business credit under federal deadlines that tighten through 2027. Ask your installer whether that savings is in your price.
