Connecticut solar energy buyers guide
Connecticut residents pay around 12% less than the national average to install solar panels, which makes solar power an attractive option. While the federal solar investment tax credit provides the biggest financial incentive for going solar, the state also has several programs to help reduce the cost or find financing to purchase solar panels.
How much does it cost to install solar panels in Connecticut?
It costs an average of $14,700 to install solar panels in Connecticut after receiving the full federal solar investment tax credit (ITC).
The total cost of your system varies based on multiple factors, including the amount of power you need to generate, the types of panels you choose, whether you include optional equipment like batteries and what local incentives are available. The best solar energy companies in Connecticut perform a site inspection to collect all necessary information before providing a detailed estimate.
You receive the most savings from going solar if you purchase your system upfront, but the significant initial investment leads many people to finance their equipment through a solar loan.
If you want to minimize your initial cost, you can typically lease your equipment or enter a power purchase agreement. However, you won’t be eligible for the federal solar ITC if you lease or enter a PPA because you won’t own the equipment.
What solar incentives are available in Connecticut?
Taking advantage of the federal solar investment tax credit is the best way to reduce the cost of installing solar panels in Connecticut. The ITC gives you a federal income tax credit that equals 30% of the total cost of your solar equipment and installation and is available for solar power systems installed by the end of 2032.
Connecticut has several state programs and incentives as well. You’ll receive a 100% sales tax exemption on solar systems and appliances, and you also receive a property tax exemption for the value your solar panels add to your home.
If you plan to finance your equipment, the state also has several loan programs that offer assistance. The programs include the Smart E-loan program, which is available for all residents, and the Energy Conservation Loan financing program.
Net metering in Connecticut
Net metering is the process of sending excess energy your system produces back to the grid for compensation. Connecticut replaced net metering with the Residential Renewable Energy Solutions Program in 2022. The program provides a flat rate for power you send back to the grid with the option of an annual cash-out or monthly credits on your electric bill.
If you don’t participate in net metering, consider purchasing a battery to store power for times when your panels aren’t producing as much electricity.
FAQ
Is going solar worth it in Connecticut?
We think installing solar panels is a good investment for most Connecticut residents. While the state doesn’t have as many local incentives as some others, the cost of going solar is about 12% less than the national average. Connecticuters who pay upfront for solar energy systems average a net savings of $42,705 over 25 years.
Can I get free solar panels in Connecticut?
There are no programs that offer free solar panels in Connecticut, but you can lease or enter a power purchase agreement for a small or no upfront cost.
Do I need a solar battery?
Solar batteries let you store energy for later use, but they’re not required for a residential solar energy system. If you choose to not purchase a battery, however, you should consider participating in net metering to earn money or credits for energy you produce but don’t use.
