Answers to common questions about solar installers in Connecticut.
The best solar installers in Connecticut are NABCEP-certified, locally based, and transparent about 2026 pricing. NuWatt Energy handles Smart-E loan applications, RRES enrollment, and Eversource/UI interconnection as part of every CT installation. Look for installers who disclose that the Section 25D federal tax credit expired December 31, 2025.
Solar installation in Connecticut costs $2.95-$3.20 per watt in 2026. A typical 10 kW system costs $29,500-$32,000. The federal 25D residential tax credit expired December 31, 2025, so there is no federal credit. CT offers sales tax exemption, property tax exemption, net metering, RRES, and Smart-E 0.99% APR financing through CT Green Bank.
No. The Section 25D residential solar tax credit expired December 31, 2025. Cash or loan purchases in 2026 receive $0 federal credit. The only way to access federal incentives is through a solar lease or PPA where a third-party owner claims the Section 48 commercial ITC.
Connecticut offers: Smart-E 0.99% APR loans through CT Green Bank (up to $50K), RRES program incentives, 1:1 net metering, full sales tax exemption on solar equipment, property tax exemption on added home value, and ConnectedSolutions battery program through Eversource/UI.
Most Connecticut solar installations take 8-12 weeks from signed contract to PTO. Design (1-2 weeks), permitting (2-4 weeks), installation (1-2 days), and Eversource/UI interconnection (2-4 weeks).
NuWatt Energy serves all of Connecticut including Greater Hartford, New Haven, Fairfield County, Shoreline, Central CT, and Litchfield Hills. We install in both Eversource and United Illuminating territories.
Smart-E is a CT Green Bank financing program covering up to $50,000 for solar, heat pumps, batteries, and other home-energy projects. Solar loans are financed at the standard Smart-E APR — 6.99% for 5-10 year terms, 7.49% for 12 years, 7.99% for 15 years. The 0.99% APR special that often gets promoted applies to qualifying heat pump installs only (extended through 6/30/2026); it does NOT apply to solar. NuWatt handles the Smart-E application as part of your installation.
