Why solar in Woonsocket

Most states lost their solar economics when the federal residential credit expired at the end of 2025. Rhode Island largely did not, because its support was never mostly federal. A Woonsocket homeowner in 2026 still has a choice between two substantial state programmes, two tax exemptions that need no application, and some of the most expensive electricity in the country to displace. That is a better position than almost anywhere else.

What ended, in context

The 30 percent federal Residential Clean Energy Credit under Section 25D expired for property placed in service after December 31, 2025. A cash or loan purchase now receives no federal tax credit, and that is a real loss.

Section 48E, the commercial credit, survives at 30 percent for third-party owners under leases and power purchase agreements. The provider claims it, and whether any of the value reaches you depends on the rate offered.

In states such as New Hampshire, Tennessee and Utah, that expiry left essentially nothing behind. Rhode Island is different because its programmes are state and utility level rather than federal.

So the honest framing here is that the stack got thinner rather than that it collapsed, and the diligence question shifts from finding incentives to choosing between them correctly.

What Rhode Island still has

A choice between net metering with a Renewable Energy Fund grant, reported at $0.65 per watt capped at $5,000 with a $2,000 storage adder, and the Renewable Energy Growth programme selling your entire output at a contracted fixed rate.

Exemption from the 7 percent state sales tax on the equipment, which is automatic and appears as an absence from the price.

A 20-year property tax exemption under RIGL 44-3-21 requiring no separate application, which is rarer than it sounds: Maine requires a filing by April 1 and New Hampshire leaves it to each town to adopt.

And residential electricity around 31 cents per kWh, among the highest in the country, which is what makes displaced consumption so valuable here.

The lease question in a state with real programmes

Because Section 48E survives for third-party owners, leases and power purchase agreements are being promoted harder in 2026 as the remaining route to a 30 percent federal credit.

In Rhode Island that trade needs examining more carefully than in a state with no programmes of its own. Ask whether a third-party owned system would still be eligible for the Renewable Energy Fund grant, and who would receive it.

Ask the same about the Renewable Energy Growth programme: who holds the contract, who receives the tariff payments, and what reaches you.

Then ask for the side-by-side against a cash purchase with the state programmes included on your side of the ledger. In a state with genuine state-level support, giving that up to capture an indirect share of a federal credit is a trade you should see in numbers.

Costing it out across the two routes

Strike the federal residential credit from any quote showing it, since Section 25D expired for property placed in service after December 31, 2025.

Rebuild from whichever route you choose: net metering to 125 percent of on-site consumption plus the Renewable Energy Fund grant, or the Renewable Energy Growth contracted tariff.

Add the 7 percent sales tax exemption and the 20-year property tax exemption under RIGL 44-3-21, both automatic and both applying on either route.

Then add the electricity you stop buying at roughly 31 cents per kWh. Ask for both routes in writing, and confirm the grant with Rhode Island Commerce and the tariff with Rhode Island Energy.

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.

Why solar + battery in Woonsocket

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.

Frequently asked questions

Did Rhode Island solar economics survive the federal credit ending?

Largely, because Rhode Island support was never mostly federal. The stack got thinner rather than collapsing: two substantial state and utility programmes remain, along with two tax exemptions that need no application.

What is actually left in 2026?

A choice between 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 contracted tariff, plus the 7 percent sales tax exemption and a 20-year property tax exemption.

Should I lease to capture the remaining federal credit?

Examine it carefully here. Ask whether a third-party owned system would still be eligible for the Renewable Energy Fund grant and who would receive it, and the same for the REG contract, then ask for the side-by-side against a cash purchase.

Why is Rhode Island still a good solar market?

Because the state-level programmes are intact and residential electricity runs around 31 cents per kWh, among the highest in the country, so displaced consumption is worth a great deal per kilowatt hour.
