Solar Thermal Incentive Program

February 11, 2015


Note: This program is not currently accepting applications. Check the program web site for information regarding future financing programs. 

To participate in the residential solar hot water rebate, homeowners must first complete an energy assessment. Then, they must work with CEFIA approved solar hot water installers. Only customers of United Illuminating or Connecticut Light & Power are eligible. Applicants are required to seek pre-approval and secure a reservation number prior to commencing work. After receiving approval, project owners have six months to complete the installation. The rebate actually goes to the solar hot water installer and the savings are passed on to the residential customer. The rebate amount is based on the Solar Rating and Certification Corporation (SRCC) ratings and the hot water needs of those living in the home.
The Connecticut Clean Energy Fund - now the Clean Energy Finance and Investment Authority (CEFIA) - started this program in 2009 using $4 million dollars from the American Recovery and Reinvestment Act State Energy Program funding to support solar hot water heating in the State. In March 2012, the CEFIA board approved interim funding to continue the residential and commercial programs while a new financing program is developed.
