Rhode Island has some of the highest electricity rates in the country — and they keep climbing.
In 2021, Rhode Island residents paid 22.3 cents per kWh. By 2024, that rose to 28.1 cents — nearly double the national average of 16.5 cents. That gap keeps growing.
Solar can help. By generating your own electricity, you pull less power from the grid — so your bill shrinks even as utility rates continue to rise.
With Palmetto’s LightReach program, there’s no upfront cost. You pay a fixed monthly rate, Palmetto owns and maintains the system, and a 90% Production Guarantee means your panels are always working for you.
Price of Energy: Rhode Island vs National Average
Rhode Island Area Utility Providers
Rhode Island has one primary electric utility: Narragansett Electric. Based on 2023 data — the most recent available — Narragansett customers paid about 27.2¢ per kWh, nearly double the national average of 16.0¢.
Rhode Island’s high rates reflect its aging grid, heavy reliance on natural gas, and limited in-state energy generation. As a small state, it has fewer options to diversify its energy supply, keeping costs stubbornly high.
When utility rates are this high, every kilowatt-hour your solar panels produce is worth more. That’s why Rhode Island homeowners considering solar installation often see strong long-term value compared to states with lower electricity costs.

Rhode Island Solar Incentives
Rhode Island homeowners can explore available solar incentives in Rhode Island at the utility level to help offset the cost of going solar.
Rhode Island does not currently offer a dedicated state solar rebate program. However, homeowners may still benefit from utility-level net metering policies and property or sales tax treatment — check with your local utility for current availability.
The federal 30% residential solar tax credit was eliminated by the 2025 Big Beautiful Bill. With a LightReach lease, Palmetto handles the commercial tax credit and passes savings through lower monthly payments.

Solar panel production varies throughout the year based on daylight hours, weather patterns, and sun intensity. Rhode Island’s mix of coastal weather and four distinct seasons shapes solar output year-round. Despite cloudy winters, the Ocean State gets enough sunshine to make solar a smart, worthwhile investment.

Go Solar with LightReach — No Upfront Cost
In Rhode Island, Palmetto’s LightReach program is available through Rhode Island Energy (formerly National Grid) via a Power Purchase Agreement (PPA). With a PPA, you pay a set price per kilowatt-hour (kWh) for the electricity your panels produce — rather than a fixed monthly amount. That means your solar bill may be a bit higher in sunny summer months and lower in winter, but you’re always paying less than standard utility rates.
Compared to buying a system outright, a PPA through LightReach removes the biggest barriers to going solar. There’s no upfront cost, no loan to manage, and no maintenance responsibilities. Since Palmetto Finance owns the system, we handle everything — from detailed solar mapping and design to permitting, installation, and ongoing service — all at no cost to you. You simply pay for the clean energy your panels produce.
LightReach also includes a 90% Production Guarantee: if your panels fall short, we’ll credit you the difference. Every plan comes with a comprehensive protection program for added peace of mind. To learn more about how leasing compares to buying, visit our solar buy or lease guide. For Rhode Island homeowners, a LightReach PPA is a straightforward, low-risk path to solar savings.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!

Rhode Island does have some form of net metering or net billing available, though specific program details can vary by utility and may change over time. Net metering generally allows solar homeowners to send excess electricity back to the grid in exchange for credits that offset future utility bills — a valuable benefit given Rhode Island’s high electricity rates.
Since policies and credit rates can be updated, we recommend contacting your local utility provider — such as Narragansett Electric — directly to confirm the current net metering terms available for your home.
Yes — but only if you own your solar panel system outright. Research from Zillow shows that homes with solar panels sell for approximately 4.1% more than comparable homes without them. For a typical Rhode Island home, that can represent a meaningful boost in resale value.
However, this benefit applies to purchased systems only. If your panels are leased — such as through a PPA arrangement — the system is owned by the solar company, not you. A prospective buyer would need to assume the lease agreement, which can complicate the sale rather than enhance your home’s value.
For Rhode Island homeowners, the most accessible way to go solar is through Palmetto’s LightReach program — a lease with no upfront cost and a low fixed monthly payment starting around $117/month. Palmetto owns and maintains the system, includes a 90% Production Guarantee, and passes tax credit savings directly to you through lower payments.
If you prefer a cash purchase, a typical 7.38 kW system in Rhode Island costs around $23,888. Note that following the 2025 federal law change, the 30% residential solar tax credit is no longer available for cash purchases. Use the calculator above for personalized pricing.
With Palmetto’s LightReach program, you pay one simple monthly fee that covers everything: the solar panel system, installation, monitoring, maintenance, and a 90% Production Guarantee. There is no upfront cost. For a typical 7.38 kW system in Rhode Island, the estimated monthly lease payment is approximately $117/month — often less than what you’re currently paying for electricity.
Because Palmetto owns the system, we claim the commercial Investment Tax Credit (ITC) and pass those savings directly to you through lower monthly payments. Many Rhode Island homeowners start saving from day one.
For Rhode Island homeowners, solar can make strong financial sense — especially given the state’s electricity rates, which are nearly double the national average at 28.1¢/kWh. With Palmetto’s LightReach lease, there’s no upfront cost. Your fixed monthly payment is typically less than your current electric bill, meaning you can start saving from day one.
Since Palmetto owns and maintains the system, you have no maintenance responsibilities. The plan includes a 90% Production Guarantee and a comprehensive protection program — making it a low-risk, accessible path to solar savings for Rhode Island homeowners.
Yes. Rhode Island averages 4.7 peak sun hours per day, which is enough to make solar a worthwhile investment. Modern panels also produce energy on cloudy days — just at reduced output. Rhode Island’s four distinct seasons do affect production, with longer summer days generating significantly more electricity than shorter winter days.
Seasonal variation is completely normal. A well-designed system accounts for Rhode Island’s coastal weather patterns year-round. Despite snowy winters and overcast stretches, the Ocean State gets enough annual sunlight to deliver meaningful energy savings for homeowners.
Yes, solar makes strong financial sense in Rhode Island. The state has some of the highest electricity rates in the country — 28.1¢/kWh, nearly double the national average — and rates have climbed 28% since 2020.
