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.
Recipients of the Commonwealth Solar II rebate will also be eligible to earn Solar Renewable Energy Certificates (“SRECs”) through participation in the newly launched RPS Solar Carve-Out. The RPS Solar Carve-Out is a market-based incentive program to support residential, commercial, public, and non-profit entities in developing solar photovoltaic (PV) projects across the Commonwealth. The Department of Energy Resrouces, which manages the RPS, has developed a price support mechanism for SRECs, the Solar Credit Clearinghouse Auction, to facilitate solar project development and financing in the SREC market. As with RPS Class I RECs, SRECs are traded on the New England Generation Information System.
