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!

In March 2012, the Clean Energy Finance and Investment Authority (CEFIA) unveiled its new solar photovoltaics residential investment program. The ultimate goal of the program is to support 30 megawatts of residential solar photovoltaics (PV). There is $40 million allocated to the program.  This residential program is limited to owner-occupied homes. Only customers of Connecticut Light & Power and United Illuminating are eligible.

There are two incentive types available, depending on the ownership of the PV system.  For consumers who purchase a solar PV system for their residence directly, systems up to 10 kilowatts (kW) receive a maximum $0.80/W. Systems greater than 10 kW and up to 20 kW receive a $0.40/W rebate. Systems greater than 20 kW are allowed, but the incentive is only paid on the first 20 kW. Systems with a calculated “design factor” greater than or equal to 87% will receive the full incentive amount. Systems with a calculated “design factor” less than 87% will receive a rebate discounted according to calculated design factor. 

For consumers who do not purchase a solar PV system directly but enter into a contract with a company that owns/operates the system, there is a performance-based incentive (PBI) available to that third party owner.  Currently, for systems up to 10kW the program offers incentive of $0.125/kWh for six years and is paid on actual performance of the PV system. Systems sized between 10kW-20kW are offered $0.060/kWh.  In both cases, there is a 5%  bonus for using components manufactured in Connecticut. All systems must be installed with a CEFIA Performance Data Provider approved monitoring system (the cost of this system has been taken into account in designing the incentive levels). 

Systems installed in a Solarize Connecticut community will receive different incentives. See program website for more information.

Interested customers are required to have a home energy audit first then select a contractor from a CEFIA approved list.  The contractor is responsible for completing all the paperwork and application materials, which are all completed online. Additional details are available on the web site.
