Connecticut residents across 96 towns and cities are served by 8 electric utilities, with residential rates ranging from 13.0¢ to 33.0¢ per kWh. Even the lowest rate is well above the national average of 16.8¢/kWh, making solar an especially strong financial investment in higher-rate utility territories.On the lowest rate ($13.0¢/kWh), a typical 8 kW system saves at least $$1,248/year — your savings scale up with your utility's rate.
The federal residential solar tax credit (Section 25D) expired at the end of 2025. This means homeowners who buy solar with cash or a loan no longer receive a federal tax credit. State and utility-level rebates are now the primary way to reduce your solar investment. Third-party owned systems (leases and PPAs) still qualify for 30% under Section 48/48E.
100% of Connecticut utilities offer net metering, allowing solar homeowners to earn bill credits for excess energy. The state has 6 municipal utilities, many offering their own rebate programs independent of statewide programs.Browse the towns below to see exact rates, incentives, and savings estimates for your specific location.
