Commonwealth Solar II Rebate Program

Commonwealth Solar II

Block 9 of the Commonwealth Solar II Rebate Program is now open.  As of 1:25PM on January 27, 2012, 142 applications have been received that are either in process or approved, and $1.22 million in funding is still available.
Commonwealth Solar II provides rebates for homeowners and businesses in Massachusetts who install solar photovoltaics (PV).  Rebates are granted through a non-competitive application process for the installation of photovoltaic (PV) projects by professional, licensed contractors at residential, commercial, industrial, institutional and public facilities.  In addition to the base incentive, further incentives (“adders”) are available for installations using components manufactured in Massachusetts, for individuals with moderate income or home values, and for those who are rebuilding in the wake of a natural disaster.  For all systems, rebates are calculated by multiplying the per watt incentive (base incentive plus adders) times the nameplate capacity of the system, up to 5 kilowatts (kW); projects are eligible for rebates only if their total capacity is under 15kW.  Rebates must be approved before the installation process begins.
