Connecticut’s solar value in 2026 comes from very high electricity rates plus the 20-year RRES tariff you lock in, not from a state cash rebate: there is no state solar income-tax credit and the 30% federal credit ended after December 31, 2025. According to MySolarFY’s analysis (as of July 2026), a typical 7.6 kW Connecticut rooftop produces about 9,500 kWh a year (NREL PVWatts, Hartford), which offsets roughly $2,700 to $3,000 a year at the state’s 30.47 cents per kWh residential rate and pays back a cash system in about 9 to 12 years now that the federal credit has ended. Your result depends on your roof, usage, RRES tariff choice, and system price.
- Connecticut residential power runs about 30.47 cents per kWh, among the highest nationally, so solar offsets an expensive bill (EIA, as of March 2026).
- RRES replaced net metering: you choose a Netting tariff (credits your exports at the retail rate) or a Buy-All tariff (sells all your production at a fixed $0.3289/kWh for 20 years, REC value included) through Eversource or United Illuminating. Note that 2026 Netting enrollees pay a $0.0402/kWh Solar Energy Adjustment (SEA) on total production; Buy-All does not (Eversource RRES; CT PURA).
- Solar equipment is exempt from the 6.35% state sales tax and the added home value is exempt from property tax (DSIRE).
- Financing: the CT Green Bank Smart-E loan offers low-interest loans for solar and home energy upgrades (CT Green Bank).
- Two catches: 2026 RRES enrollees pay a higher production charge than earlier customers, and Connecticut’s Solar for All award was targeted for federal termination in 2025 and is unresolved (CT DEEP).
- The 30% federal homeowner credit (Section 25D) ended for expenditures made after December 31, 2025 (IRS).
Connecticut solar pays off in 2026 for one main reason: homeowners here pay about 30.47 cents per kWh for electricity (EIA retail sales, residential CT, as of March 2026), among the highest rates in the country, so every kilowatt-hour your roof makes offsets an expensive bill. Connecticut also pays for solar differently than it used to, through the Residential Renewable Energy Solutions (RRES) program rather than classic net metering. This page explains what Connecticut solar costs and saves, how RRES pays you, the rest of the 2026 incentives, and how to find your town or utility.
Why solar pays in Connecticut
Connecticut has some of the highest power prices in the country. At about 30.47 cents per kWh, a Connecticut home with a $150 to $300 monthly bill offsets expensive grid power with every kilowatt-hour the roof makes, and that high rate is the main reason solar pencils out here, even without an upfront state rebate. Your production drives both your bill savings and your RRES payments, so estimate your roof’s likely output with NREL’s free PVWatts calculator; actual output depends on your roof’s pitch, orientation, and shading. The thing to understand in Connecticut is the RRES choice, which the next section walks through.
| Typical system size | 7.6 kW rooftop |
| Estimated yearly production | About 9,500 kWh (NREL PVWatts, Hartford; varies with roof and shading) |
| Residential electricity rate | 30.47 cents per kWh (EIA, as of March 2026) |
| Gross yearly bill offset | About $2,700 to $3,000 |
| 2026 Netting adjustment | Minus $0.0402/kWh SEA on total production (about $380 a year) for 2026 Netting enrollees |
| Assumed cash install price | About $3.00 to $3.50 per watt, so roughly $22,800 to $26,600 before any financing |
| Federal 25D credit | $0 (ended for expenditures after December 31, 2025) |
| Estimated cash payback | About 9 to 12 years, after the 2026 SEA and with the federal 25D credit ended for expenditures after December 31, 2025 |
This is a MySolarFY estimate built from the real EIA rate and a live NREL PVWatts run, not a quote. Your own payback depends on your roof, usage, RRES tariff choice, and installer price. Financed and lease/PPA paths change the math.

Connecticut solar incentives at a glance
Connecticut’s stack is solid, but the 2026 details have shifted. Here is what each one pays and the catch worth knowing.
| Incentive | What it does | 2026 status | Who receives it | Source |
|---|---|---|---|---|
| RRES tariff (Netting or Buy-All) | Pays you for the power your system makes | Active; Buy-All $0.3289/kWh fixed 20 years (REC included), Netting credits exports at retail minus a $0.0402/kWh Solar Energy Adjustment for 2026 enrollees | The system owner of record | CT PURA |
| Sales-tax exemption | Waives state sales tax on equipment | 100% of the 6.35% rate (CGS 12-412(117)) | The buyer | DSIRE |
| Property-tax exemption | Excludes solar’s added value from assessment | 100% for qualifying residential systems (CGS 12-81(57)) | The owner | DSIRE |
| CT Green Bank Smart-E loan | Low-interest financing for solar | Active in 2026; confirm current rate | The owner-occupant borrower | CT Green Bank |
| Solar for All | Federal low-income solar help | Targeted for federal termination in 2025; unresolved, not a reliable 2026 program | Unresolved | CT DEEP |
| Federal residential (Section 25D) | A 30% homeowner credit | Ended for expenditures made after December 31, 2025 | No 2026 homeowner-buyer | IRS |
The headline is the RRES choice plus high rates. Connecticut replaced classic net metering with the Residential Renewable Energy Solutions program on January 1, 2022, so new systems enroll in an RRES tariff through Eversource or United Illuminating rather than spinning the meter backward (CT PURA). One honest note for 2026: Netting systems enrolling on or after January 1, 2026 pay a $0.0402/kWh Solar Energy Adjustment on total production, so the economics are a little tighter than for earlier enrollees, though Connecticut’s high rates still make solar attractive (Eversource RRES). Pre-2022 net-metered customers are generally grandfathered on their old terms.
Heads up, two catches: first, the 2026 RRES terms carry a higher production charge than earlier years, so ask your installer to model your specific payback under both tariffs with current numbers. Second, Connecticut’s federal Solar for All award (Project SunBridge) was targeted for termination in August 2025 and its status is unresolved, so do not count on it; income-eligible households should look at the RRES low-income adders and CT Green Bank financing instead. Ask a tax professional about your situation. MySolarFY does not provide tax advice.

The RRES choice: Netting or Buy-All
First, this runs through your utility. Connecticut has two investor-owned electric utilities, Eversource, which serves most of the state, and United Illuminating (UI), which serves the New Haven and Bridgeport area on the coast. The Residential Renewable Energy Solutions tariff is administered through whichever one serves you, under rules set by the Public Utilities Regulatory Authority (PURA), so the Netting and Buy-All terms are the same statewide whether your bill comes from Eversource or UI (CT PURA).
This is the decision that defines a Connecticut solar quote. You enroll in one of two tariffs for a 20-year term, so it pays to understand both.
| Netting tariff | Buy-All tariff | |
|---|---|---|
| How it works | You use your solar on-site and export the excess | The utility buys all your production and you buy back what you use |
| What you are paid | Exports credited at the retail rate, minus a $0.0402/kWh Solar Energy Adjustment (SEA) on total production for 2026 enrollees | A fixed rate, about $0.3289/kWh, for everything you generate |
| Best when | You use a lot of your own power during the day | Your usage and production are mismatched, or you want a fixed price |
| Term | 20 years | 20 years |
| Source | CT PURA | CT PURA |
How to think about it. Netting rewards using your own solar power as you make it, since exports are credited at the retail rate but 2026 enrollees pay a $0.0402/kWh Solar Energy Adjustment (SEA) on total production (Eversource RRES). Buy-All hands the utility all your production at a fixed price and bills you for what you use, which can suit a home whose usage does not line up with its solar output. Because the 2026 production charge changed the math, the right answer depends on your usage pattern, so ask your installer to run both. For a side-by-side of the 2026 numbers on each option, see the real Netting versus Buy-All math for Connecticut. For how export credits work in general, see how net metering credits your solar exports, and to weigh payback, see the financial case for whether solar panels are worth it.
Low-income and economically distressed-municipality customers can earn adders on either tariff, and to see how the credit lowers your monthly cost, read how solar lowers your electricity bill.
How you pay changes which incentives you keep
The way you finance solar decides who is the system owner of record, and that decides who holds the RRES tariff.
| How you pay | Up-front cost | Who owns the system | RRES tariff | Tax exemptions |
|---|---|---|---|---|
| Cash | Full system price | You | Yours, in your name | Yours |
| Solar loan (e.g. Smart-E) | Little or none, financed over time | You | Yours, in your name | Yours |
| Lease or PPA | $0-up-front where you qualify | A third-party company | The company holds the tariff | Follow ownership |
If you own the system (cash or a Smart-E loan), the RRES tariff is in your name and you keep the sales-tax and property-tax exemptions. If you lease or sign a PPA, the company that owns the panels holds the tariff, and your benefit is a lower or fixed power price with no up-front cost. Neither path gives a 2026 Connecticut homeowner the federal residential credit, since that credit ended after December 31, 2025. For the federal timeline, see what the federal solar tax credit change means in 2026.
What changed federally, and what it means for Connecticut
The federal homeowner credit is gone, but Connecticut’s high rates and tax exemptions are not. The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a Connecticut homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS OBBB FAQ; SEIA). The RRES tariffs, the sales-tax and property-tax exemptions, and CT Green Bank financing were not affected, and at Connecticut’s high rates the bill offset alone is substantial. For the full timeline, see what the federal solar tax credit change means in 2026.
One federal exception exists, and it is not yours to claim. A separate commercial credit, Section 48E, is claimed by the business that owns a leased or PPA system, not by the homeowner, and it runs for projects placed in service through 2027, with a begin-construction safe harbor by July 4, 2026 (IRS Clean Electricity Investment Credit; SEIA tax policy). For a leased system in Connecticut you do not file for a federal credit yourself; the company that owns the panels does. The 25D homeowner credit, by contrast, ended after December 31, 2025.
How to choose a solar installer in Connecticut
Connecticut has a deep market of licensed installers. Rather than chasing a “best” list, screen any installer against objective criteria:
- NABCEP certification, the industry’s professional standard for PV installers.
- Proper Connecticut licensing and any required local electrical and building permits.
- A clear workmanship and equipment warranty in writing.
- Real Connecticut experience and verifiable reviews, plus help choosing your RRES tariff and enrolling through Eversource or United Illuminating.
- A written production estimate and a transparent quote that models both RRES tariffs. For a checklist, see the right questions to ask a solar installer.
MySolarFY matches you with licensed installers that serve your area so you can compare real local quotes side by side, with no obligation.

Frequently asked questions
What solar incentives does Connecticut offer in 2026?
Connecticut’s main support is the Residential Renewable Energy Solutions program, where you choose a Netting or a Buy-All tariff through Eversource or United Illuminating, with the Buy-All rate around $0.3289/kWh fixed for 20 years (CT PURA). On top of that, solar is exempt from the 6.35% state sales tax and from property tax, and the CT Green Bank Smart-E loan offers low-interest financing. Connecticut does not offer a state solar income-tax credit, and at its high electricity rates the bill savings are the biggest driver.
What happened to the federal solar tax credit?
The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act. A Connecticut homeowner who buys solar in 2026 with cash or a loan cannot claim it. A separate commercial credit (Section 48E) can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner. Connecticut’s RRES tariffs and tax exemptions were not affected. See our guide on what the federal solar tax credit change means in 2026.
How does the RRES program work, and should I pick Netting or Buy-All?
RRES is Connecticut’s successor to net metering. The Netting tariff lets you use your own solar and credits your exports at the retail rate, minus a production charge, which suits homes that use a lot of power during the day. The Buy-All tariff sells all of your production to the utility at a fixed rate, about $0.3289/kWh for 20 years, and you buy back what you use at retail (CT PURA). Because the 2026 production charge changed the math, the better option depends on your usage, so ask your installer to model both before you choose.
Does Connecticut tax solar?
Barely. Connecticut exempts qualifying residential solar equipment from its 6.35% state sales tax and exempts the added home value from property tax, so a system does not raise your assessment (DSIRE). A 2025 to 2026 capacity tax change applies to large, utility-scale solar, not residential rooftops, so it does not affect a typical home system. Connecticut has no state solar income-tax credit, so the tax benefit is the two exemptions rather than a credit on your return.
What is the status of Connecticut’s Solar for All program?
It is unresolved. Connecticut received a federal Solar for All award known as Project SunBridge in 2024, but the EPA targeted the national program for termination in August 2025, the same action that hit Maine and Pennsylvania (CT DEEP). As of 2026 there is no reliable, active enrollment for households through it. Income-eligible homeowners should instead look at the low-income adders built into the RRES tariffs and at CT Green Bank financing, which are available now.
Do I qualify for CT solar incentives if I lease or sign a PPA?
The RRES tariff goes to the system owner of record, so if you lease or sign a PPA, the third-party company holds the tariff, and your benefit is a lower or fixed power price with no up-front cost. The sales-tax and property-tax exemptions follow ownership of the equipment and the property. The CT Green Bank Smart-E loan is for owner-occupants who finance a system they own. If you want the RRES tariff and the exemptions in your own name, owning the system through cash or a loan is the path that captures them.
