  • Massachusetts Solar Loan Program

    In December 2015, DOER, in partnership with the Mass Clean Energy Center (MassCEC), launched the $30 million residential Solar Loan Program.  The program provides funding to Massachusetts banks and credit unions to incentivize lenders to make solar lending a part of their portfolios and to make solar loans available to borrowers with lower incomes or credit scores. For more information, visit the Mass Solar Loan Website.  

  • Solar Energy: Facts [U.S. Dept. of Energy]

    This U.S. Department of Energy (DOE) database of frequently asked questions focuses on technologies for photovoltaics, solar heating, and concentrating solar power (CSP).
  • Solar Carve-Out / SREC I

    Beginning in January 2010, the Department of Energy Resources (DOER) carved-out a portion of the RPS Class I Renewable Energy requirement to support distributed solar photovoltaic (PV) energy facilities, as provided by the Green Communities Act of 2008. Statement of Qualification Applications from facilities seeking qualification under the program were accepted through April 25, 2014.
  • Rooftop Solar Challenge

    Thanks to a U.S. Department of Energy SunShot Initiative Rooftop Solar Challenge grant, Massachusetts will pilot programs to identify and implement best practices that streamline permitting, interconnection, financing and zoning of solar PV projects in five selected pilot communities. The programs will develop models to replicate throughout Massachusetts.

  • Distributed Generation (DG) and Interconnection

    If you install behind-the-meter distributed energy resources, such as solar panels, CHP, storage, or wind turbines to provide electricity on your site, the Massachusetts Interconnection and Distributed Generation Website has resources to help you understand the process to connect to your electric company. Information at the website includes Standards for Interconnection (Tariffs), Monthly DG Workshops, Utility Interconnection Time Frame Performance, the quarterly MA Technical Standards Review Group, and utility circuit data to aid low cost, high value site selection.
