ConnecticutSolar Incentives 2026: Tax Credits, Rebates & Net Metering
Connecticut homeowners can reduce solar installation costs by up to 30% through state and federal incentives. With average monthly bills of $215 and 4.3 peak sun hours per day, the average CT homeowner saves $46,700 over 25 years.
State Solar Tax Credit
Connecticut does not offer a state income tax credit specifically for residential solar. Most homeowners rely on the 30% federal Residential Clean Energy Credit as the primary up-front incentive.
Even without a state income credit, Connecticut's property tax exemption and sales tax exemption on solar equipment significantly reduce effective lifetime cost.
Net Metering in Connecticut
Connecticut requires investor-owned utilities to offer net metering on residential solar systems. The credit rate is a modified rate (typically retail rate minus a small grid utilization fee).
In practice, this means a properly sized Connecticut system can drive net annual electricity costs to within tens of dollars of zero. Top utilities operating under CT net metering rules include Eversource, UI.
Utility Rebate Programs
2 major utilities operate in Connecticut: Eversource, UI. Specific rebate availability varies year to year and is typically distributed first-come, first-served until annual budget caps are reached.
Before scheduling any installation, verify current rebate status directly with your utility — programs open and close throughout the year. Most Connecticut installers will pull up-to-date rebate data during a site assessment.
Property & Sales Tax Exemptions
Connecticut excludes the added value of a residential solar system from property tax assessments. A homeowner whose property gains $15,000 in assessed value from a solar install pays no additional property tax on that increase, saving roughly $250 to $400 annually depending on local mill rates.
Connecticut also exempts solar equipment from state sales tax, removing roughly 4% to 7% from the up-front cost of panels, inverters, and racking depending on local rate.
CT SREC Market
Connecticut has an active Solar Renewable Energy Certificate (SREC) market. Homeowners earn one SREC for every megawatt-hour produced and sell them on the CT compliance market.
At current clearing prices, the average CT homeowner earns approximately $8,500 in SREC income over the first five years of operation. SREC values are volatile and depend on the state's Renewable Portfolio Standard compliance demand each year.
