Solar incentives in Connecticut
The federal solar investment tax credit (ITC) is the best way to save money when going solar in Connecticut. If you install a residential solar panel system by the end of 2032, you can deduct 30% of the system's total cost from your federal taxes. This includes equipment, labor and permit costs.
The ITC drops to 26% in 2033 and 22% in 2034.
For example, for a $14,700 system, you can get a $4,410 credit when you file your taxes.
To get your tax credit, you must claim it on your federal taxes for the same year that your solar panel system was installed on Form 5695.

Statewide residential solar incentives in Connecticut
Connecticut doesn’t have many solar incentives for homeowners. There are a few, including tax breaks and low-interest, fixed-rate loan programs.
Connecticut residents can get a 100% exemption on the value a solar energy system adds for the purpose of property tax assessments. There’s also a 100% sales tax exemption on solar systems and appliances, such as solar water heaters. This can save homeowners a large chunk of money.
Connecticut has several solar loans to help you finance your new system. The Smart E-loan program, for example, offers loans that vary between five and 12 years with a fixed interest rate between 4.49% and 6.99% at the time of publishing. This loan is available to all residents, including low-income homes.
Another option is the Energy Conservation Loan financing program. It allows you to get a fixed-rate loan with a cap of up to $25,000 for up to 12 years. You can qualify for zero interest if your family is below 50% of the median income. Others qualify for loans with an interest rate of up to 7%.
What to know about net metering in Connecticut
Net metering is a system that lets you use excess energy produced by your solar system that isn’t stored in a battery. The extra is passed on to the electric grid. Then your local electricity company pays for the energy in bill credits.
In Connecticut, net metering was replaced by the Residential Renewable Energy Solutions Program in 2022. To qualify, your solar system must be up to 20 kilowatts (kW) in size. You can get a flat rate for your power with the option of a cash-out each year or monthly credits on your electric bill, much like with net metering.
