Why is solar still worth it in Connecticut without the federal credit?

Connecticut's electricity is among the most expensive in the U.S. (about 27 to 29 cents per kWh). High rates plus sales- and property-tax exemptions keep payback attractive even though the federal credit is gone.

Solar Panels in Connecticut (2026 Guide)

Q: How much do solar panels cost in Connecticut in 2026?

Roughly $2.70 to $2.90 per watt before incentives — about $13,000 to $14,500 for a 5 kW system and $26,000 to $29,000 for 10 kW.

Q: Does Connecticut have a solar tax credit?

There is no state income-tax credit, but Connecticut offers a 100% sales-tax exemption and a permanent property-tax exemption on solar. The 30% federal credit expired December 31, 2025 and is not available in 2026.

Q: Does Connecticut still have net metering?

Traditional net metering is closed to new customers. New systems use the RRES program — choose the Netting Tariff for net-metering-style retail credits, or Buy-All to sell all production at a fixed rate.

Q: Are there battery incentives in Connecticut?

Yes — the Energy Storage Solutions program pays incentives for home batteries, with extra value for low-income and outage-prone customers. Program terms changed in 2026, so confirm current amounts.

Connecticut has some of the highest electricity rates in the country — which is exactly why solar still pays off here, even though the federal tax credit is gone. The state replaced its old solar rebate with a new tariff program (RRES), and it keeps full sales-tax and property-tax exemptions on solar. This guide covers what's actually available in 2026, what each program is worth, and the one decision that most affects your payback.

How Much Do Solar Panels Cost in Connecticut?

Connecticut installs average roughly $2.70–$2.90 per watt before incentives. For a typical home system:

5 kW system: ~$13,000–$14,500
10 kW system: ~$26,000–$29,000

Your real price depends on your roof, panel choice, and installer. The average Connecticut system runs on the larger side because homes here use a lot of expensive grid power to offset. See our 2026 solar cost breakdown.

Connecticut Solar Incentives in 2026

No federal tax credit in 2026

First, the honest part: the 30% federal residential solar tax credit expired December 31, 2025 and is not available for systems installed in 2026. A lot of older sites still advertise it — ignore that. See our 2026 tax credit guide.

The RRES tariff (Connecticut's main solar program)

Connecticut retired its old rebate and traditional net metering. New systems enroll in the Residential Renewable Energy Solutions (RRES) program, run by Eversource and United Illuminating under state regulators (PURA). You pick one of two options, locked in for 20 years:

Netting Tariff — the closest thing to old-school net metering. Your panels power your home first, and extra energy you export earns bill credits at the retail rate, rolling over month to month. Best for most homeowners who want to offset their own usage.
Buy-All Tariff — you sell all your production to the grid at a fixed rate and buy back everything your home uses at retail. This suits some households but separates your production from your consumption.

Which one you choose is the single biggest factor in your payback, so model both with your installer.

Sales & property tax exemptions

Solar equipment and installation are fully exempt from Connecticut's 6.35% sales tax (roughly $1,500–$2,000 on an average system), and the added home value is permanently exempt from property tax — so you get the resale bump without a higher tax bill.

Battery storage — Energy Storage Solutions (ESS)

Connecticut's Energy Storage Solutions program pays incentives for home batteries, with combined upfront-plus-performance value that can reach the mid-five figures for qualifying installations, and larger payments for low-income and outage-prone households. The program's structure changed in 2026, so confirm current values with your installer. More in our solar + battery guide.

Net Metering / Export Credits in Connecticut

Traditional net metering is closed to new customers — it's been replaced by the RRES tariff above. If you choose the Netting Tariff, you get something that behaves much like net metering: you offset your own use first, then bank excess exports as credits. One 2026 note: new enrollees pay a small per-kWh charge on their solar production (a "Solar Energy Adjustment"), which slightly trims savings versus earlier customers. Your installer can show how it affects your numbers.

Major Connecticut Utilities

Two utilities serve nearly all of Connecticut, and both administer RRES:

Eversource — the largest, covering most of the state.
United Illuminating (UI) — serving the greater New Haven and Bridgeport areas.

Connecticut's all-in residential rates run around 27–29¢ per kWh — roughly 50% above the national average. Even with some interim rate reductions in 2026, power here stays expensive, which is the core reason solar economics work.

Is Solar Worth It in Connecticut in 2026?

For most homeowners with decent roof sun, yes. The math is no longer powered by a federal credit — it's powered by very high electricity rates plus full sales- and property-tax exemptions and the retail-rate Netting tariff. Payback periods are longer than in the federal-credit era, but Connecticut's expensive power means every kWh you offset is worth a lot. The make-or-break variables are your tariff choice (Netting vs Buy-All) and whether you add storage. A custom quote for your utility is the only way to see your real payback.
