The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

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.
