Going solar in Rhode Island
The smallest state in the nation fosters some of the biggest solar savings for its residents. Rhode Island’s solid incentives, coupled with the sky-high electricity prices, make solar panels a good investment for pretty much anyone in the Ocean State.
Factor in the federal solar tax credit and Rhode Islanders can cut the cost of solar by thousands of dollars, speeding up their payback periods and increasing the value of their investments.
Here's what you need to know about going solar in Rhode Island.
Cost
How much do solar panels cost in Rhode Island?
Solar panels cost a lot to install, but they can save tons of money over time by shrinking or eliminating your electricity bills. The average Rhode Island homeowner needs a 10.2 kW solar panel system to cover their electricity needs, which comes out to $32,558 before incentives. Prices range from $27,674 to $37,442 before incentives. After the federal tax credit, that drops by 30%, and Rhode Island has some local incentives as well.
As a Rhode Islander, you can participate in either the Renewable Energy Growth (REG) Program or a Renewable Energy Fund (REF) Small Scale Solar Grant (but not both). These are both first-come, first-serve incentives where you can earn $0.27 per kWh or $0.65 per watt (up to $5,000), respectively.
Solar pays off in Rhode Island.That's why over 14,000 Rhode Island homeowners have used EnergySage to receive and compare quotes for solar installations. You can expect to earn back your initial solar investment through electricity savings in about 6.81 years, while most systems last at least 25 years. You'll often see this number referenced as your solar payback period.
Solar panel systems are expensive, but there are ways to finance your investment and reduce upfront costs.
Cash purchase: You pay for your system outright, which typically provides the best long-term savings.
Solar loan: You pay for your system in monthly installments like a lease but maintain ownership like a cash purchase. Generally, the best solar loans are subsidized clean energy loans through local incentive programs. If you don’t have access to that, a home equity loan or a personal loan are often your next best options. Private solar loans typically come with higher interest rates or upfront fees.
Solar lease or power purchase agreement (PPA): You make monthly payments on your system like a loan, but a third-party company owns your system. You’ll either sign a solar lease or purchase the electricity the panels generate through a PPA. Third-party ownership models typically deliver the lowest savings and have earned some bad press. If you choose this financing option, read the fine print: You can get trapped in them for longer than you'd like.

Is net metering available in Rhode Island?
In some states, you'll earn bill credits from your utility company when your solar panel system generates excess electricity and sends it to the grid. This incentive is known as net metering—basically a solar buyback program—and makes it so you will owe very little, or even nothing, on your electric bills with solar panels.
Under Rhode Island’s net metering program, you’ll earn credits at the retail rate of electricity for each kWh of electricity your system produces, up to 100% of your monthly utility electricity demand. If you send more electricity to the grid than you demand, you’ll be credited based on the avoided cost rate for your excess generation. Net excess generation credits are limited to 125% of your utility usage.
All major utilities in Rhode Island offer their own net metering program, so make sure to cash in on it while it's still available. Learn more about net metering in Rhode Island or get program details below:
Equipment
Equipment quality
Solar panels continue to get more efficient, meaning they produce more power per square foot. In 2025, the most popular solar panels can produce about 450 watts of electricity in full sunlight—you’ll want panels with at least that much power output to get the most out of your installation.
It’s also important to choose a solar inverter setup that works for your roof’s layout.
And if you plan to install a solar battery, pick one that can easily integrate with that inverter.
While premium equipment can result in sticker shock, it typically saves you more money in the in the long run: The highest-quality panels degrade at a slower rate and maintain more of their power output for longer, and the best warranty terms often guarantee up to 40 years of coverage in case you need repairs or replacements.
