Solar Panels for Home in Connecticut: Overview
Connecticut has some of the highest residential electricity rates in the country, averaging $0.25 to $0.30/kWh. That's roughly double the national average. This one fact does more for solar economics than any incentive program could. Even without the federal 30% ITC (which ended in December 2025), Connecticut homeowners installing solar are offsetting very expensive grid electricity, which produces some of the fastest payback periods in the country.
The state's policy framework reinforces it. Full retail-rate net metering through Eversource and United Illuminating, a 15-year property tax exemption, a sales tax exemption on solar equipment, and the ConnectedSolutions battery program all combine into a strong overall picture.
Connecticut's old Residential Solar Investment Program ran from 2012 to about 2022 and helped install tens of thousands of residential systems. The direct rebates from RSIP are gone, but the market infrastructure it built (trained installers, streamlined permitting, predictable utility interconnection processes) is still in place. Going solar in Connecticut is genuinely smoother than in states without that history.

How Much Do Solar Panels Cost in Connecticut?
Connecticut averages 4.0 to 4.5 peak sun hours per day, which is moderate by national standards, similar to New York and less than Virginia or North Carolina. But the solar resource is only half the equation. The other half is the cost of the electricity you're replacing, and that's where Connecticut runs away from the rest of the country for solar economics.
The state has over 55,000 residential solar installations. Despite being geographically small, Connecticut consistently ranks in the top 10 states for solar per capita. The market is mature and competitive, with national companies like SunPower, Tesla Solar, and Sunrun working alongside experienced regional installers like Trinity Solar, Momentum Solar, and the Solarize CT participants.
Installation costs in Connecticut run $2.90 to $3.30 per watt, slightly above the national average. The higher labor and permitting costs in the Northeast are partially offset by the competitive installer market.
Eversource serves roughly 75% of Connecticut electricity customers. United Illuminating covers the Bridgeport-New Haven corridor. Both utilities have well-established solar interconnection processes.
Is Solar Worth It in Connecticut? Installation Cost & Savings
Connecticut is one of the best states in the country for solar ROI, despite moderate sunshine. The math is driven by those extremely high electricity rates.
A typical 7 kW system costs $20,300 to $23,100 here. The sales tax exemption saves about $1,300, dropping the effective cost to roughly $19,000 to $21,800. Annual electricity savings come in at $1,800 to $2,500 at Connecticut's $0.27/kWh average rate. Payback periods land at 8 to 11 years, up from 6 to 8 when the federal credit was still available. The property tax exemption prevents $400 to $800 per year in additional property taxes for 15 years. Twenty-five year savings often run $35,000 to $50,000+.
Add a battery and ConnectedSolutions to the picture: another $10,000 to $15,000 for the battery, with $1,000 to $1,500 per year in ConnectedSolutions revenue offsetting it. Combined solar plus battery payback comes in at 10 to 13 years, with exceptional long-term returns afterward.
Where solar pencils out best in Connecticut: monthly bills above $200 (common across CT), Eversource customers with retail-rate net metering, homeowners interested in ConnectedSolutions battery revenue, and south-facing roofs paired with a 10+ year stay.
Even homes with moderate bills see solar pay off faster in Connecticut than in most other states. The high rates do most of the work.
Net Metering in Connecticut
Connecticut's net metering policy is one of the strongest in the country. Residential systems up to 25 kW qualify. Both Eversource and UI credit excess generation at the full retail rate. Credits roll over month to month throughout the year. An annual true-up happens once per year, at which point any remaining excess credits may be paid out at a wholesale rate or forfeited (the specifics vary by utility). The program isn't capped for individual residential customers.
Virtual net metering is also available, which enables community solar projects. That matters for renters, condo owners, and homeowners whose roofs aren't suitable for panels. Subscribing to a community solar project lets you capture solar credits on your bill without owning hardware.
Connecticut's Public Utilities Regulatory Authority (PURA) oversees net metering policy. PURA has been generally supportive of distributed solar, but as adoption grows, future adjustments to the compensation structure are possible. For now, the full retail rate makes the math straightforward.
Solar Tax Exemptions in Connecticut
Connecticut's tax exemptions are substantial and meaningfully change the overall economics.
Property tax exemption: solar energy systems are exempt from property tax for 15 years following installation. After 15 years, the remaining value (if any) may be assessed. This prevents a property tax increase from solar for the bulk of the system's productive life, which is a real ongoing benefit.
Sales tax exemption: solar equipment is exempt from Connecticut's 6.35% state sales tax. On a $21,000 system, that saves about $1,300 up front.
What Connecticut doesn't offer: a state solar tax credit or rebate (RSIP rebates ended), or a state battery storage purchase incentive (though ConnectedSolutions provides ongoing revenue, see the energy storage section below).
The federal 30% ITC expired in December 2025 for new installations. Without it, the property and sales tax exemptions become the primary upfront incentives alongside net metering savings.
Battery Storage Incentives in Connecticut
Connecticut has been ahead of most states on residential battery storage policy. The ConnectedSolutions program, run through Eversource and UI, pays residential battery owners for allowing their storage systems to discharge during peak grid demand events. Those events typically hit on summer afternoons and winter evenings.
Here's how it works in practice. Homeowners enroll their battery (Tesla Powerwall, Enphase, or similar) in the program. During called events, the battery discharges to support the grid. Participants receive annual payments of roughly $225 to $300 per enrolled kW of battery capacity. A typical 13 kWh battery can earn $1,000 to $1,500 per year through the program. ConnectedSolutions runs year-round with seasonal adjustments.
That ongoing revenue stream meaningfully improves battery economics in a way you don't see in most states. A battery that earns $1,000 or more per year through ConnectedSolutions can pay for itself in 8 to 12 years on program payments alone, before counting any self-consumption or backup value.
Battery storage also provides backup power during the nor'easters and tropical storm remnants that occasionally cause multi-day outages in Connecticut.
Frequently Asked Questions About Solar in Connecticut
Does Connecticut offer solar rebates in 2026?
The original RSIP rebate program has ended. Connecticut now supports solar through a 15-year property tax exemption, a 6.35% sales tax exemption on equipment, and full retail-rate net metering. The ConnectedSolutions program provides annual revenue for battery storage owners. The federal 30% ITC expired in December 2025.
Are Connecticut electricity rates high enough to justify solar?
Yes, by a wide margin. Connecticut has among the highest residential electricity rates in the country at $0.25 to $0.30/kWh, roughly double the national average. Each kWh you generate from solar replaces very expensive grid power. Payback periods of 8 to 11 years are typical, with 25-year savings often running $35,000 to $50,000+.
What is ConnectedSolutions in Connecticut?
ConnectedSolutions is a demand response program through Eversource and UI that pays battery storage owners for discharging during peak grid demand events. Participants earn roughly $1,000 to $1,500 per year for a typical home battery. The revenue stream meaningfully improves the economics of adding battery storage to a solar system.
How much do solar panels cost in Connecticut?
Residential solar in Connecticut runs $2.90 to $3.30 per watt, slightly above the national average due to Northeast labor costs. A 7 kW system costs roughly $20,300 to $23,100. The sales tax exemption saves about $1,300, and net metering at CT's high retail rates produces substantial annual savings.
Is solar worth it in Connecticut without the federal tax credit?
Yes. Connecticut's extremely high electricity rates ($0.25 to $0.30/kWh) mean solar produces exceptional savings regardless of the federal credit expiration. Payback periods of 8 to 11 years are among the fastest in the country. The property tax and sales tax exemptions further improve the economics.
