Rhode Island solar and battery programs.
What's available, in plain language, with a link to the official source for each one. Checked October 31, 2026.
Renewable Energy Fund (REF) Small-Scale Program
A state grant that lowers the upfront cost of a solar system you own, for homeowners and micro businesses. The project must be net metered, and your installer applies. It cannot be combined with the Renewable Energy Growth program. Applications come in funding rounds. The last round Rhode Island Commerce listed closed October 16, 2026, and no 2027 round was posted when we checked.
$1.65 per watt up to 8.8 kW, with a maximum of $14,500 per project. A project with qualifying energy storage can get a $5,000 adder.

Net metering
Home solar earns a net metering credit for production up to what you use in a billing period. Production above that earns a smaller credit, which Rhode Island Energy says is based on the wholesale price for usage on and after May 12, 2026.
