Connecticut has the second highest electricity rates in the US, following Hawaii. That’s a result of location and energy market laws in the state. While Connecticut may not receive as much sunlight as states like Arizona, solar energy is still a great way for you to save money and use a renewable energy source if you live there.
Residential solar prices have decreased by over 50% in the last decade, according to the Solar Energy Industries Association. Meanwhile electricity rates in Connecticut increased by 11.8% from November 2021 to 2022. Connecticut residents pay an average monthly bill of $170.55, the third highest in the country, according to SaveOnEnergy, which is owned by CNET’s parent company. Installing solar panels at home may reduce your energy costs while also helping the environment.

Connecticut solar panel incentives and rebates
You can buy solar panels in Connecticut with an upfront cash payment or finance them over time with a solar loan. While paying for a system with cash or a loan will save you the most over time and give you access to tax rebates and incentives, solar leases and power purchase agreements are also available in Connecticut and offer lower upfront costs.
Federal and state incentives and rebates help make solar panels more affordable. The residential clean energy credit is a federal solar tax credit offering 30% towards the purchase of a solar system as a credit on your federal tax return. This could be a savings of nearly $11,400 for the average system size in Connecticut. Additional incentives could lower the price more.

Installation factors to consider
When determining if installing a solar system is right for you, keep in mind the following five things to consider.
Neighborhood and home owners associations: Connecticut doesn’t have laws prohibiting home owners associations from banning solar panels. Before installation, review your HOA or other neighborhood association rules regarding solar panel systems and their placement.
Access to sunlight: Solar panels will generate less energy if your roof is shaded by trees or other elements most of the day. Solar panels start to make financial sense when get direct sunlight for at least 4 hours a day.
Home insurance: Communicate with your homeowner’s insurance agency to ensure solar panels are included in your policy.
Do you rent?: Renters have less decision-making power than homeowners when making property changes. Community solar programs are a great option for renters as a subscription-style service from companies like Arcadia.
Roof condition: A certified installer should inspect your roof before finalizing your system placement and installation. The installer will recommend any needed maintenance and repairs before your system is installed.
