The goal of the States Advancing Solar project is to strengthen the ability of the states and other non-federal entities to further develop the market for solar photovoltaic (PV) and solar thermal systems.

CESA members are committed to expanding the use of solar technologies and driving down solar costs. The challenge is to develop the most effective state and community programs to create real markets for solar use for decades to come. To reach this goal, CESA staff continues to survey and identify solar program best practices from around the country, to develop collaborative initiatives between the states, DOE, and national solar industry members, and to provide information and analysis to CESA members on solar program design. CESA tracks, evaluates, publicizes, and facilitates state adoption of effective financial, policy, and technology activities and best practices that accelerate solar technologies.

CESA is managing a project under the U.S. Department of Energy’s SunShot Initiative Rooftop Solar Challenge II program to reduce the costs of solar deployment across five New England states. The project, called the New England Solar Cost-Reduction Partnership, will help build the regional solar market by targeting non-hardware “soft” costs for photovoltaic (PV) electricity systems and increasing coordination across Connecticut, Massachusetts, New Hampshire, Rhode Island, and Vermont. Under this award, CESA and these five New England states will tackle a range of barriers to PV deployment, including permitting and interconnection standardization challenges; the need for new financing tools; and planning and zoning rule variations. CESA will communicate lessons learned and best practices to CESA members beyond New England.
