Why solar in Rhode Island

Rhode Island still has one of the better incentive stacks left in the country, and it asks you to make a choice most states do not. There are two routes for a residential system and you may take one or the other, not both. Under the first you stay on net metering, receiving bill credits for generation up to 125 percent of your on-site consumption in a billing period, and apply for a Renewable Energy Fund grant, reported at $0.65 per watt capped at $5,000 with a $2,000 storage adder, available to net-metered systems only. Under the second you enter the Renewable Energy Growth programme, selling your entire output to Rhode Island Energy at a fixed rate for a long contract term. The programme year opens on April 1 and runs first come, first served until fully subscribed. On top of either, solar is exempt from the 7 percent sales tax and, under RIGL 44-3-21, from local property tax for 20 years from installation with no separate application. Rhode Island residential electricity runs around 31 cents per kWh, among the highest in the country.

Incentives & rebates

Net metering: Net metering to 125% of consumption, or the REG tariff instead

Rhode Island offers two mutually exclusive routes for a residential solar system, and choosing between them is the most consequential decision in the project. The first is net metering: the customer receives bill credits for all power generated up to 125 percent of on-site consumption during a billing period, and remains eligible for a Renewable Energy Fund grant, which has been reported at $0.65 per watt capped at $5,000 with a $2,000 adder for storage. The 125 percent figure functions as a sizing ceiling expressed against your own usage rather than as a fixed kilowatt limit, so a household that reduces its consumption after installing solar can find its system sitting above the useful range. The second route is the Renewable Energy Growth programme, administered by Rhode Island Energy, under which the customer sells the entire output of the system at a fixed tariff rate for a long contract term rather than offsetting their own consumption. That trades the upside of rising retail rates for a known, contracted income, and it excludes the Renewable Energy Fund grant, which is available to net-metered systems only. The programme year opens on April 1 and enrolment runs first come, first served until fully subscribed, so timing matters in a way it does not for net metering. Ask any installer to model both routes on the same system, over the same term, with the grant included on the net metering side, and to state the assumptions behind each.

Frequently asked questions

How much do solar panels cost in Rhode Island?
Rhode Island solar averages roughly $3.05 per watt installed, and the 7 percent state sales tax does not apply to the equipment. The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025, so a cash or loan purchase no longer receives it.
What incentives are available in Rhode Island?
Either net metering with a Renewable Energy Fund grant, reported at $0.65 per watt up to $5,000 plus a $2,000 storage adder, or the Renewable Energy Growth programme selling your entire output at a fixed rate under a long contract. You may take one route or the other, not both. On top of either, the 7 percent sales tax exemption and a 20-year property tax exemption under RIGL 44-3-21 apply.
Is solar worth it in Rhode Island?
For most homes with a usable roof, yes, and Rhode Island remains one of the better markets in the country. Residential electricity runs around 31 cents per kWh, among the highest anywhere, and the state-level support is unusually intact for 2026. The decision that matters most is which of the two routes you take.
