Rhode Island Solar Incentives 2026: What Homeowners Need to Know

If you are thinking about going solar, understanding Rhode Island solar incentives in 2026 is an important place to start.

The incentive landscape has shifted, and timing, program selection, and system design all play a role in overall value. Rhode Island continues to offer strong state-level programs that can reduce upfront costs and improve long-term returns.

At Newport Solar, we work with homeowners across Rhode Island to navigate these programs and design systems that align with both performance goals and available incentives.

The Federal Tax Credit Is Gone. Here’s What That Means for You

One of the most common questions we are hearing right now is whether the federal solar tax credit is still available.

The federal investment tax credit (ITC) previously allowed homeowners to deduct 30% of their solar installation costs from their federal taxes. For many Rhode Island homeowners, this played a meaningful role in the overall economics of going solar.

As of 2026, that incentive is no longer available for residential solar installations completed after December 31, 2025.

Rhode Island homeowners are now relying more heavily on state-level programs, such as the REF grant, net metering, and battery incentives, to offset system cost and drive long-term value.

Rhode Island remains one of the stronger solar markets due to its local incentives and high electricity rates.

What Solar Incentives Are Available in Rhode Island in 2026

Rhode Island offers several solar incentives in 2026 that can reduce system cost, improve long-term returns, and increase overall value for homeowners.

There are two primary solar incentive paths in Rhode Island:

• Net Metering paired with the Renewable Energy Fund (REF) grant

• The Renewable Energy Growth (REG) program

Homeowners must choose between these two options, as they cannot be combined.

Each approach works differently and impacts how your system generates value over time.

In addition to these core programs, Rhode Island also offers battery incentives, tax benefits, and other programs that can further improve the economics of going solar.

1. Rhode Island REF Grant Solar Program

The Rhode Island Renewable Energy Fund (REF) Grant is one of the most impactful solar incentives available to homeowners in Rhode Island in 2026.

This program provides an upfront cash grant based on system size:

• $1.65 per watt installed

• Up to $14,500 per project

• Additional $5,000 available when paired with battery storage

In many cases, this represents one of the largest upfront solar incentives available at the state level.

To qualify, the system must meet minimum solar exposure requirements, and approval must be secured before installation begins. The grant is paid after the system is installed and interconnected.

At Newport Solar, we guide homeowners through the REF application process and ensure timing and eligibility are aligned before moving forward.

2. Rhode Island Net Metering

Rhode Island's net metering policy allows homeowners to earn bill credits when their solar system produces more electricity than the home uses.

That excess energy is sent back to the grid and applied as a credit to your utility bill.

All non-REG projects are automatically enrolled in net metering, and the REF grant can be paired with net metering to reduce upfront cost while still capturing ongoing bill savings.

3. Renewable Energy Growth Program (REG)

The Renewable Energy Growth (REG) program is a long-term incentive that pays homeowners for the electricity their solar system produces.

The program is administered by Rhode Island Energy and offers:

• A fixed rate per kilowatt-hour (kWh)

• 15 or 20-year contract terms

• Predictable, long-term income based on system production

Current rates are approximately:

• $0.3155/kWh for 15-year terms

• $0.2865/kWh for 20-year terms

Unlike the REF grant, which reduces upfront cost, the REG program provides ongoing payments over time.

The REG program cannot be combined with the REF grant, so homeowners must choose between the two approaches. In many residential scenarios, we find the REF grant paired with net metering offers more flexibility, but the right option depends on your goals, system design, and how you plan to use your energy.

4. Connected Solutions Battery Incentive

If you install a home battery with your system, Rhode Island Energy’s Connected Solutions program provides additional value.

Through this program, your battery is used during periods of peak demand, helping support the grid when electricity usage is highest.

• Earn approximately $225 per kW each summer

• Compensation is based on how your battery performs during these peak demand events

For homeowners considering battery storage, this program can add meaningful value over time.

5. Agricultural Energy Grant Program

The Rhode Island Office of Energy Resources (OER) offers the Agricultural Energy Grant Program, which provides grants of up to $20,000 for eligible energy efficiency and renewable energy projects on farms throughout Rhode Island.

Is Solar Worth It in Rhode Island in 2026?

Yes, solar continues to be a strong investment for homeowners in Rhode Island in 2026.

Electricity rates in Rhode Island remain among the highest in the country, typically around $0.28 to $0.29 per kWh. That means every kilowatt-hour your solar system produces carries more value compared to other regions.

While the incentive landscape has shifted, programs like the REF grant, net metering, and Connected Solutions continue to support strong system economics.

The key is designing the right system and selecting the right incentive path based on how your home uses energy.

How Much Can I Save Going Solar in Rhode Island?

Savings will vary based on system size, energy usage, and the incentive program selected.

Below is an example of a 8.8 kW solar system (20 panels) that qualifies for the REF Grant:

• System cost: $31,500

• Annual solar production: 11,500 kWh per year

• REF grant: $14,500 upfront reduction

• Net system cost: approximately $17,000

Based on current electricity rates and system performance:

• Annual bill savings: $3,000 to $3,300

• Additional REC income: approximately $300 per year

This results in an estimated payback period of approximately 4 to 6 years.

Actual results will vary depending on system design, usage patterns, and program selection.

Why Your Installer Matters More Than Ever in 2026

Understanding Rhode Island’s solar incentive programs is important, but how your system is designed and executed matters just as much.

Programs like the REF grant require approval before installation begins, and timelines, documentation, and system design all need to align correctly. The REG program involves coordination with Rhode Island Energy and long-term production planning.

At Newport Solar, our in-house licensed team handles system design, permitting, installation, and interconnection. We do not subcontract our work.

We take a thoughtful approach to each project, designing systems around how the home uses energy, how incentives apply, and what will perform reliably over time.

Frequently Asked Questions

Can I still get a federal tax credit for solar in Rhode Island in 2026?

No, the federal tax credit for residential solar systems expired on December 31, 2025. Rhode Island homeowners can still take advantage of state-level incentives, including the REF grant, net metering, and programs like Connected Solutions for battery storage.

For homeowners exploring ways to structure a project without the federal tax credit, you can learn more about available options on our financing page.

What is the Rhode Island REG program? How do I qualify?

The REG program is a long-term payment initiative that pays homeowners a fixed rate per kilowatt-hour for solar production over 15 or 20 years. To qualify, your system must be connected through Rhode Island Energy, be sized appropriately for your home’s energy use, and meet criteria.

How does net metering work in Rhode Island in 2026?

Rhode Island’s net metering policy allows you to earn bill credits when your solar system produces more electricity than your home uses. Excess energy is sent back to the grid, and those credits are applied to your utility bill.

How long does it take to go solar in Rhode Island in 2026?

The timeline depends on system size, permitting, and utility coordination. Most residential projects move from initial consultation to installation and activation over the course of several months.
