Solar Panels for Home in Connecticut: Overview
Connecticut has some of the highest residential electricity rates in the country — averaging $0.25–$0.30/kWh, roughly double the national average. This single fact makes solar panels more financially attractive here than in states with twice the sunshine but half the electricity cost. Even without the federal 30% ITC (which expired December 2025), Connecticut homeowners who install solar offset very expensive grid electricity, resulting in some of the fastest payback periods in the nation.
The state's policy framework backs this up. Full retail-rate net metering through Eversource and United Illuminating (UI), a 15-year property tax exemption, a sales tax exemption on solar equipment, and progressive battery storage programs through ConnectedSolutions all contribute to a strong overall picture.
Connecticut's landmark Residential Solar Investment Program (RSIP) 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, utility interconnection procedures — remains in place and makes going solar in Connecticut relatively smooth compared to states without that history.

How Much Do Solar Panels Cost in Connecticut?
Connecticut averages 4.0–4.5 peak sun hours per day — moderate by national standards, about the same as 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 excels 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 — both national companies (SunPower, Tesla Solar, Sunrun) and experienced regional installers (Solarize CT participants, Trinity Solar, Momentum Solar) serve the state.
Average installation costs in Connecticut run $2.90–$3.30/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 return on investment, despite moderate sunshine. The math is driven by those extremely high electricity rates.
Typical economics (2026, no federal credit): • Average 7 kW system cost: $20,300–$23,100 • Sales tax savings (6.35% exemption): ~$1,300 • Effective system cost: ~$19,000–$21,800 • Annual electricity savings: $1,800–$2,500 (at $0.27/kWh average) • Estimated payback period: 8–11 years (up from 6–8 when the federal credit was available) • Property tax exemption: prevents $400–$800/year in additional property taxes for 15 years • 25-year savings: $35,000–$50,000+
With battery storage and ConnectedSolutions: • Add $10,000–$15,000 for battery • ConnectedSolutions revenue: $1,000–$1,500/year • Combined solar+battery payback: 10–13 years, with exceptional long-term returns
Strong "yes" scenarios: • High electricity bills ($200+/month — common in CT) • Eversource customers with retail-rate net metering • Homeowners interested in ConnectedSolutions battery revenue • South-facing roof, plan to stay 10+ years
Even for homes with moderate bills, Connecticut's high rates mean solar starts saving money faster than in most other states.
Net Metering in Connecticut
Connecticut's net metering policy is one of the strongest in the country:
• Available for residential systems up to 25 kW • Both Eversource and UI credit excess generation at the full retail rate • Credits roll over month-to-month throughout the year • Annual true-up occurs once per year — at settlement, remaining excess credits may be paid out at a wholesale rate or forfeited (varies by utility) • The program is not capped for individual residential customers
Virtual net metering is also available, enabling community solar projects. This is valuable for renters, condo owners, and homeowners whose roofs aren't suitable for panels — they can subscribe to a community solar project and receive credits on their bill.
Connecticut's Public Utilities Regulatory Authority (PURA) oversees net metering policy. PURA has been generally supportive of distributed solar, but as solar penetration grows, future adjustments to net metering compensation are possible. For now, the full retail rate makes the economics straightforward.
Solar Tax Exemptions in Connecticut
Connecticut's tax exemptions are substantial and make a real difference in 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 your solar investment for the bulk of the system's productive life
Sales tax exemption: • Solar equipment is exempt from Connecticut's 6.35% state sales tax • On a $21,000 system, this saves approximately $1,300 — a meaningful upfront reduction
What Connecticut does NOT offer: • A state solar tax credit or rebate (RSIP rebates have ended) • State battery storage purchase incentive (though ConnectedSolutions provides ongoing revenue — see energy storage section)
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, administered through Eversource and UI, pays residential battery owners for allowing their storage systems to discharge during peak grid demand events (typically summer afternoons and winter evenings).
ConnectedSolutions details: • Homeowners enroll their battery (Tesla Powerwall, Enphase, etc.) in the program • During called events (peak demand periods), the battery discharges to support the grid • Participants receive annual payments of roughly $225–$300 per enrolled kW of battery capacity • A typical 13 kWh battery can earn $1,000–$1,500/year through the program • The program runs year-round with seasonal adjustments
This ongoing revenue stream meaningfully improves battery storage economics and sets Connecticut apart from most states. A battery that earns $1,000+/year through ConnectedSolutions can pay for itself in 8–12 years just from program payments, separate from any self-consumption or backup value.
Battery storage also provides backup power during the severe weather events (nor'easters, 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?
Connecticut's original RSIP rebate program has ended. The state 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 December 2025.
Are Connecticut electricity rates high enough to justify solar?
Absolutely. Connecticut has among the highest residential electricity rates in the US at $0.25–$0.30/kWh — about double the national average. Each kWh you generate from solar replaces very expensive grid power. Payback periods of 8–11 years are typical, with 25-year savings of $35,000–$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–$1,500/year for a typical home battery. This revenue stream significantly improves the economics of adding battery storage to your solar system.
How much do solar panels cost in Connecticut?
Average residential solar costs in Connecticut range from $2.90 to $3.30 per watt — slightly above the national average due to Northeast labor costs. A 7 kW system costs approximately $20,300–$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–$0.30/kWh) mean solar provides exceptional savings regardless of the federal credit expiration. Payback periods are 8–11 years — among the fastest in the nation. Property tax and sales tax exemptions further improve the economics.
