Commonwealth Solar II

The Commonwealth Solar II Rebate Program has closed, as of January 2015. Please see our About Solar Electricity page for information on the basics of going solar and to learn about available incentives. 

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.  Further eligibility requirements apply, and potential rebate recipients should read the full program documentation
