- Rhode Island residential power runs about 29.91 cents per kWh, well above the national average, so solar offsets an expensive bill (EIA, as of March 2026).
- The Renewable Energy Fund (REF) grant pays $0.65 per watt, up to $5,000 for residential solar, plus a $2,000 battery adder, but it cannot be combined with the REG tariff (RI Commerce; RI Energy Office).
- The Renewable Energy Growth (REG) program instead pays a fixed rate for all your production over 15 or 20 years, recently around 32 to 34 cents per kWh; the 2026 residential rate is pending state approval (RI Energy Office).
- You choose REG or net metering for a system, not both. New net-metered systems are credited at about 80% of the retail rate (RI Energy Office).
- Solar is exempt from the 7% state sales tax and from local property tax statewide under RIGL 44-3-3(a)(48) (DSIRE).
- The 30% federal homeowner credit (Section 25D) ended for expenditures made after December 31, 2025 (IRS).
Rhode Island homeowners pay about 29.91 cents per kWh for electricity (EIA retail sales, residential RI, as of March 2026), well above the U.S. average, so cutting that bill is worth real money. Rhode Island’s twist is that you choose between two state paths: an upfront grant with net metering, or a long-term production tariff. This page explains both, the rest of the 2026 incentives, and how to tell which one fits your home.
Why solar pays in Rhode Island
High rates plus a real upfront grant is the reason. At about 29.91 cents per kWh, a Rhode Island home with a $150 to $300 monthly bill offsets expensive grid power with every kilowatt-hour the roof makes. Rhode Island is one of the few states still offering a direct cash grant toward a home system through the Renewable Energy Fund. Your production drives both your savings and your REG payments, so estimate your roof’s likely output with NREL’s free PVWatts calculator; actual output depends on your roof’s pitch, orientation, and shading. For the numbers behind this, see our Rhode Island solar data and statistics page, which gathers the current rate, per-city production, cost, and payback with every figure dated and sourced.
Rhode Island solar incentives at a glance
Rhode Island’s programs come with a fork in the road and some fine print. Here is what each one pays in 2026 and the catch worth knowing.
| Incentive | What it pays | 2026 value and status | Who receives it | Source |
|---|---|---|---|---|
| REF grant | Upfront cash toward your system | $0.65/W up to $5,000, plus a $2,000 battery adder; budget-capped rounds | The system owner (not lease or PPA homeowners) | RI Commerce |
| REG tariff | A fixed price for all your production | Recently about 32 to 34 cents/kWh for 15 to 20 years; 2026 rate pending approval | The contract holder | RI Energy Office |
| Net metering | A bill credit for power you export | About 80% of retail for new systems; choose this or REG, not both | The account holder | RI Energy Office |
| Sales-tax exemption | Waives state sales tax on equipment | 100% of the 7% rate | The buyer | DSIRE |
| Property-tax exemption | Excludes solar’s added value from assessment | 100%, statewide under RIGL 44-3-3(a)(48) | The owner | DSIRE |
| Federal residential (Section 25D) | A 30% homeowner credit | Ended for expenditures made after December 31, 2025 | No 2026 homeowner-buyer | IRS |
The grant is the headline, but it is owner-only and capped. The Renewable Energy Fund, run by Rhode Island Commerce, pays $0.65 per watt up to $5,000 for a residential system, with an extra $2,000 if you add a battery at the same time (RI Commerce). It is awarded in scheduled application rounds on a first-come basis until each round’s budget runs out, so timing matters, and it goes to whoever owns the system. The grant cannot be combined with the REG tariff, which is the choice the next section walks through.

The Rhode Island choice: REF plus net metering, or REG
This is the decision that defines a Rhode Island solar quote. You enroll a system in one path or the other, and you cannot mix them.
| Path A: REF grant plus net metering | Path B: REG tariff | |
|---|---|---|
| Upfront cash | REF grant of $0.65/W up to $5,000 | None |
| Ongoing payment | Net-metering credits, about 80% of retail for new systems | A fixed rate for all production, recently 32 to 34 cents/kWh |
| Term | Net metering is ongoing | 15 or 20 year contract |
| Best when | You want money down now and self-consume most of your power | You want a long, predictable production payment |
| Source | RI Commerce | RI Energy Office |
How to think about it. Path A puts cash in your pocket now through the REF grant and credits your exports through net metering, which suits a household that uses much of its own solar. Path B skips the grant and instead pays a fixed rate for every kilowatt-hour the system makes for 15 or 20 years, which can suit a larger system that exports a lot. Because the 2026 REG rate was still pending approval, get current numbers for both before you choose. For the mechanics of export credits, see how net metering credits your solar exports, and to weigh payback, see the financial case for whether solar panels are worth it. For a side-by-side of what each path pays with the verified 2026 numbers, see our Rhode Island solar incentives guide for 2026.
Net metering in Rhode Island
The value depends on when you connect. Systems interconnected before April 15, 2023 were grandfathered at close to the full retail rate. For systems applied for after that date, Rhode Island Energy credits exported power at about 80% of the retail rate, and any annual surplus above your usage is paid at a lower avoided-cost rate (RI Energy Office). Residential systems can be sized up to about 125% of your recent usage. The 80% tier sits under a statewide cap, and the state is due to review the policy by late 2026, so confirm the current terms with your installer. To see how the credit lowers your monthly cost, read how solar lowers your electricity bill.
How you pay changes which incentives you keep
The way you finance solar decides who owns the system, and ownership decides who collects the REF grant or signs the REG contract.
| How you pay | Up-front cost | Who owns the system | REF grant or REG | Net metering |
|---|---|---|---|---|
| Cash | Full system price | You | Yours to claim | Yours |
| Solar loan | Little or none, financed over time | You | Yours to claim | Yours |
| Lease or PPA | $0-up-front where you qualify | A third-party company | The company keeps the grant or tariff | Yours, follows the account |
If you own the system (cash or loan), you take the REF grant or sign the REG contract yourself, plus net metering and the tax exemptions. If you lease or sign a PPA, the company that owns the panels keeps the grant or the REG payments, and your benefit is a lower or fixed power price with no up-front cost. Neither path gives a 2026 Rhode Island homeowner the federal residential credit, since that credit ended after December 31, 2025. For the full federal timeline, see what the federal solar tax credit change means in 2026.
What changed federally, and what it means for Rhode Island
The federal homeowner credit is gone, but Rhode Island’s programs are not. The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a Rhode Island homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS OBBB FAQ; SEIA). The REF grant, the REG tariff, net metering, and the tax exemptions were not affected, and the REF grant in particular replaces some of the lost upfront value. For the full timeline, see what the federal solar tax credit change means in 2026.
One federal exception exists, and it is not yours to claim. A separate commercial credit, Section 48E, is claimed by the business that owns a leased or PPA system, not by the homeowner, and it runs for projects placed in service through 2027, with a begin-construction safe harbor by July 4, 2026 (IRS Clean Electricity Investment Credit; SEIA tax policy). For a leased system in Rhode Island you do not file for a federal credit yourself; the company that owns the panels does. The 25D homeowner credit, by contrast, ended after December 31, 2025.
How to choose a solar installer in Rhode Island
Rhode Island has a solid market of licensed installers. Rather than chasing a “best” list, screen any installer against objective criteria:
- NABCEP certification, the industry’s professional standard for PV installers.
- Proper Rhode Island licensing and any required local electrical and building permits.
- A clear workmanship and equipment warranty in writing.
- Real Rhode Island experience and verifiable reviews, plus help with your REF grant application or REG enrollment and net-metering interconnection.
- A written production estimate and a transparent quote you can compare. For a checklist, see the right questions to ask a solar installer.
MySolarFY matches you with licensed installers that serve your area so you can compare real local quotes side by side, with no obligation.

Frequently asked questions
What solar incentives does Rhode Island offer in 2026?
Rhode Island gives you a choice between two paths. Path A is the Renewable Energy Fund grant of $0.65 per watt up to $5,000 (plus a $2,000 battery adder) combined with net metering. Path B is the Renewable Energy Growth tariff, which pays a fixed rate, recently about 32 to 34 cents per kWh, for all your production over 15 or 20 years (RI Commerce; RI Energy Office). On top of either path, solar is exempt from the 7% state sales tax and from local property tax statewide. There is no separate state income-tax credit.
What happened to the federal solar tax credit?
The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act. A Rhode Island homeowner who buys solar in 2026 with cash or a loan cannot claim it. A separate commercial credit (Section 48E) can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner. Rhode Island’s REF grant, REG tariff, net metering, and tax exemptions were not affected. See our guide on what the federal solar tax credit change means in 2026.
Should I choose the REF grant or the REG program?
You have to pick one, because the REF grant cannot be paired with the Renewable Energy Growth program (RI Commerce). The REF path gives you upfront cash plus net-metering credits, which fits a home that uses most of its own power. The REG path skips the grant and pays a fixed rate for every kilowatt-hour you produce for 15 or 20 years, which can fit a larger, export-heavy system. Because the 2026 REG rate was still pending approval, ask your installer to model both with current numbers before you decide.
How does net metering work in Rhode Island?
Rhode Island Energy credits the power you export, but the rate depends on when you connect. Systems interconnected before April 15, 2023 were grandfathered near the full retail rate, while newer systems are credited at about 80% of retail, with any annual surplus paid at a lower avoided-cost rate (RI Energy Office). Residential systems can be sized up to about 125% of your recent usage. Remember that net metering and the REG tariff are mutually exclusive, so a net-metered system is on Path A with the REF grant.
How much is the Rhode Island REF solar grant?
The Renewable Energy Fund residential grant, run by Rhode Island Commerce, pays $0.65 per watt of installed solar, capped at $5,000 per project, with an additional $2,000 if you add a battery at the same time (RI Commerce). It is awarded in scheduled rounds on a first-come basis until each round’s budget runs out, so it can close mid-year. The grant goes to the system owner, so a lease or PPA customer does not receive it directly, and it cannot be combined with the REG tariff.
Do I qualify for RI solar incentives if I lease or sign a PPA?
It depends on the incentive. The REF grant and the REG contract go to whoever owns the system, so on a lease or PPA the third-party company keeps them, not you. What you get instead is a lower or fixed power price with no up-front cost. Net-metering credits follow the utility account, so they still reduce your bill. If you want the grant or the tariff in your own name, owning the system through cash or a loan is the path that captures it.

MySolarFY is a free service that matches homeowners with licensed solar installers. We are not an installer, financing company, or government program. “No up-front cost” refers to qualifying lease or PPA financing, where eligible homeowners may have no out-of-pocket cost at installation. Lease and PPA terms typically run 20 to 25 years, may include an annual price escalator, and total payments may exceed the cost of a cash purchase; on a lease or PPA the REF grant and the REG tariff go to the company that owns the system, not the homeowner. Homeowners do not get the federal residential credit that ended after December 31, 2025. Solar panels are not free and monthly payments apply.
