About this incentive

Commerce Rhode Island provides financial grants for small scale solar photovoltaic systems and domestic solar water heating systems to help reduce energy costs and increase renewable energy adoption. The program is funded by the Rhode Island Renewable Energy Fund (REF) and alternative compliance payments (ACPs) from the state’s renewable portfolios standard (RPS). The application for grants are solicited on a "Block" basis with specific application deadlines. Eligibility All residential, business, affordable housing, non-profits, state facilities, and municipalities located in Rhode Island are eligible to apply for the grant. Systems that are directly owned are eligible. Customers participating in RE Growth Program offered by National Grid are not eligible to participate in the program. Grants are available for solar photovoltaic systems up to 7.69 kilowatts (kW) (anything above will receive the max) in capacity and domestic solar water-heating systems. There is also a flat adder available for programs with energy storage projects. Project owners must have conducted an energy audit prior to application submission.
