Rhode Island program mechanics, exemptions, and federal credit status reviewed August 2026.
Rhode Island genuinely pays for residential solar, and it makes you choose how: the Renewable Energy Growth program, a fixed performance payment for every kilowatt-hour your system produces, locked for 20 years at enrollment, for systems up to 25 kW, or net metering, which credits your exports against your bill. A system enrolls in one or the other, not both. Around that election sit a competitive grant from the Renewable Energy Fund and statewide sales and property tax exemptions that apply quietly no matter which path you pick.
Most Rhode Island regret we see traces to the election being made by default, by whoever wrote the quote. Make it on purpose.
Sort your Rhode Island election before the quote does
The Election, Side by Side
Question | Renewable Energy Growth | Net metering |
|---|---|---|
What you receive | A fixed payment per kilowatt-hour for 20 years, set at enrollment, for systems up to 25 kW | Exports up to 100% of your annual consumption credit at close to the full retail rate, 1-to-1; production between 100% and 125% credits at avoided cost, and nothing above 125% is paid |
How long the terms hold | Fixed for the full 20-year term set at enrollment | Recent credit reductions apply only to remote ground-mounted projects; rooftop systems keep full credit |
Who it tends to fit | Households that want contracted, predictable payments | Households with high usage that offsets most production on the bill |
How you get in | Annual program enrollment through Rhode Island Energy, with capacity allocations | Standard interconnection and tariff election |
Which path wins for a given house is a modeling question, run properly in whether solar is worth it in Rhode Island against the entry prices in what solar costs in Rhode Island.
The full 2026 inventory, with the status of each piece:
Program | What it pays | 2026 status |
|---|---|---|
Renewable Energy Growth (REG) | Fixed per-kWh payment for 20 years, set at enrollment | Open via annual enrollment, systems up to 25 kW |
Net metering | Close to full retail 1-to-1 up to 100% of annual use; avoided cost from 100% to 125% | Open; one path or the other, never both |
Renewable Energy Fund grant | Competitive grant toward small-scale solar | Round-based; confirm the current round before counting it |
Sales tax exemption | 7% off qualifying equipment | Active |
Property tax exemption | No added assessment for residential systems | Active |
Federal 25D credit | $0 | Ended for systems you own completed after December 31, 2025; 48E remains for third-party owners only |
The Grant Behind the Quote
The Renewable Energy Fund, administered through Rhode Island Commerce, awards grants toward small-scale solar in funded rounds. Two cautions:
- It is competitive and round-based. Funding exists until it does not; your contract should state what happens to the price if an expected grant is not awarded.
- It is usually applied for through your installer, which means its value should be visible in your quote as a named line you can see and audit in the price.
The Quiet Exemptions
Two statewide breaks apply regardless of the election. Solar equipment is exempt from Rhode Island sales tax at purchase, and residential renewable systems are exempt from property taxation, so the system should not raise your assessment. Neither shows up as a check, and both belong in any full accounting of what the state contributes.
You Will Likely Miss the Money If
- A third party owns the system. In lease and power purchase structures, performance payments and grants flow to whoever owns the system. Who collects is the whole question in what free solar really means in Rhode Island.
- The election was never discussed. If your proposal does not say which path it assumes and why, the modeling behind it is decorative.
- Your quote banks an unawarded grant. Priced-in money you have not received is risk wearing a discount’s clothes.
- You expect the federal credit. It is $0 for systems you own whose installation is completed after December 31, 2025. Only third-party owners in lease and PPA deals can still claim a federal credit, and it goes to them.

Frequently Asked Questions
Rhode Island’s solar incentives in 2026 are the Renewable Energy Growth performance payment program, net metering as its alternative, competitive Renewable Energy Fund grants, and statewide sales and property tax exemptions. The federal residential credit ended for systems you own whose installation is completed after December 31, 2025; only third-party owners in lease and PPA deals can still claim a federal credit.
No state income tax credit, and the federal credit is now $0 for purchased systems. Rhode Island’s support arrives as performance payments, grants, and tax exemptions instead.
A tariff program through Rhode Island Energy paying a fixed rate per kilowatt-hour your system produces for 20 years, set at enrollment for systems up to 25 kW, enrolled in annual capacity allocations. It replaces net metering for enrolled systems, which is why choosing between them deliberately matters.
No. A system takes one path or the other. The right choice depends on your usage shape and appetite for contracted payments versus bill offsets, and it should be modeled both ways before anything is signed.
Rhode Island Commerce awards grants in funded rounds, typically applied for through your installer. Treat it as conditional money: named in the quote, contingent in the contract, never assumed until awarded.
Residential renewable energy systems are exempt from property taxation in Rhode Island, and solar equipment is exempt from sales tax at purchase. Both apply regardless of which compensation path you elect.
