  • About Solar Energy: Passive Solar, Solar Thermal, and Photovoltaic

  • 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.
  • Commonwealth Solar II

    Administered by the Massachusetts Clean Energy Center, this program provides rebates for the installation of small residential and commercial solar photovoltaic systems.
  • Solarize Massachusetts

    Ten communities are participating in 2013 Solarize Massachusetts, which builds on the success of the last two years' programs. This joint DOER / MassCEC program works with cities and towns to drive down the installation cost and increase adoption of small-scale solar PV installations.

  • Residential Solar Loan Program

    DOER is currently developing a residential solar loan program. The goal of the program is to reduce barriers for Massachusetts residents to directly own solar projects by facilitating access to loans by local banks.

  • 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 new technology or a system, such as solar panels, a wind turbine or CHP, to generate electricity on your site, there are resources to help you understand the process and connect to your energy provider.
