Rhode Island solar notes
Rhode Island's Renewable Energy Growth program pays a fixed performance tariff as an alternative to net metering, and very high retail rates make solar compelling.
Heads up: the 30% federal tax credit for purchased home solar ended Dec 31, 2025. Leased/PPA systems may still qualify through 2027, and Rhode Island may offer its own incentives — check locally.
