What solar incentives are available in Rhode Island in 2026? Rhode Island homeowners pick one of two state paths: the Renewable Energy Fund cash grant paired with net metering credited at about 80% of the retail rate, or the Renewable Energy Growth tariff, which pays a fixed rate up to 31.55 cents per kWh for 15 years. Solar equipment is also exempt from the 7% state sales tax and from local property tax.
- 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 is upfront cash toward a residential system, and it cannot be combined with the REG tariff. The RI Office of Energy Resources lists $0.65 per watt, up to $5,000, plus a $2,000 battery adder (RI Energy Office, as of August 2026); some 2026 sources report RI Commerce raised the residential grant, so confirm the current round’s per-watt rate and cap with RI Commerce before you budget.
- The Renewable Energy Growth (REG) program instead pays a fixed rate for all your production. For Program Year 2026 to 2027 (effective April 1, 2026), the residential ceiling is $0.3155 per kWh for Small-Scale Solar I systems of 1 to 15 kW over a 15-year term, and $0.2865 per kWh for 15 to 25 kW systems over 20 years (RI Energy Office, RIPUC-approved tariff; as of August 2026).
- 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. According to MySolarFY’s analysis (August 2026), a 7 kW rooftop system in Providence produces about 9,246 kWh in its first year (NREL PVWatts, ZIP 02909), worth roughly $2,770 a year against Rhode Island’s 29.91 cents per kWh residential rate, before you add the REF grant or a REG contract. 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. For what a system costs and when it pays back in Rhode Island, see our Rhode Island solar cost and payback guide.
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 | RI OER lists $0.65/W up to $5,000, plus a $2,000 battery adder; budget-capped rounds. Some 2026 sources report a higher grant, so verify the current round with RI Commerce | The system owner (not lease or PPA homeowners) | RI Commerce |
| REG tariff | A fixed price for all your production | $0.3155/kWh (1 to 15 kW, 15 yr) or $0.2865/kWh (15 to 25 kW, 20 yr) for Program Year 2026 to 2027, effective April 1, 2026 | 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, capped, and cycle-dependent. The Renewable Energy Fund, run by Rhode Island Commerce, pays a per-watt cash grant toward a residential system. The RI Office of Energy Resources lists $0.65 per watt up to $5,000, with an extra $2,000 if you add a battery at the same time (RI Energy Office, as of August 2026). Some 2026 installer sources report RI Commerce increased the residential grant this year, and the state summary and RI Commerce’s round documents can disagree, so confirm the current round’s per-watt rate and project cap directly with RI Commerce before you budget. The grant 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. It 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, $0.3155/kWh for 1 to 15 kW (Program Year 2026 to 2027) |
| 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. For the current REG ceiling prices and an original REG-versus-net-metering comparison for a Providence home, see our Rhode Island Renewable Energy Growth (REG) program guide. The Program Year 2026 to 2027 REG ceiling took effect April 1, 2026, but ceiling prices reset each year, so 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. For the full breakdown of the 80% credit rule, the April 15, 2023 grandfathering line, the avoided-cost true-up, and a worked Providence example, see our Rhode Island net metering guide for 2026. To see how the credit lowers your monthly cost, read how solar lowers your electricity bill. Renters or anyone not ready to install can still trim the supply half of the bill by comparing competitive suppliers with Empower RI.
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, and for state-specific credentials read how to choose a solar installer in Rhode Island.
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, which the RI Office of Energy Resources lists at $0.65 per watt up to $5,000 (plus a $2,000 battery adder), combined with net metering; some 2026 sources report a higher grant, so verify the current round with RI Commerce. Path B is the Renewable Energy Growth tariff, which pays a fixed rate for all your production over a 15 or 20 year contract. For Program Year 2026 to 2027 (effective April 1, 2026), the residential ceiling is $0.3155 per kWh for 1 to 15 kW systems and $0.2865 per kWh for 15 to 25 kW systems (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, recently a $0.3155 per kWh ceiling for 1 to 15 kW residential systems in Program Year 2026 to 2027, which can fit a larger, export-heavy system. Because REG ceiling prices reset each year, 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, is a per-watt cash grant capped per project. The RI Office of Energy Resources lists $0.65 per watt up to $5,000, with an additional $2,000 for adding a battery at the same time (RI Energy Office, as of August 2026). Some 2026 sources report RI Commerce raised the residential grant this year, so confirm the current round’s per-watt rate and cap directly with 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.
