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 local incentives 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 will save you a lot of money over time, but the upfront costs aren't cheap. The average Rhode Island homeowner needs a 10.67 kW solar panel system to cover their electricity needs, which comes out to $32,419 before incentives. Prices range from $27,556 to $37,282, but Rhode Island also has some great local incentives. 

While this may sound high, it will pay off in Rhode Island. That's why over 15,000 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 9.17 years, while most systems last at least 25 years. You'll often see this number referenced as your solar payback period.

There are a few ways to finance your solar panel system so you don't have to provide all that money upfront. 

  • Cash purchase: You'll own the system and pay for it up front. This provides the best long-term savings. 

  • Solar lease or power purchase agreement (PPA): A third-party company owns your system and either leases you the solar panels (solar lease) or allows you to purchase the electricity they generate (PPA). These typically deliver immediate savings and can make a lot of sense if you’re looking to keep your capital flexible. Just make sure to choose an offering with low annual escalators to ensure it will continue to provide long-term savings. 

  • Solar loan: This allows you to retain ownership of your system while owing little to no money upfront. Solar loans aren't all created equal. If you have access to subsidized clean energy loans through local incentive programs, that's usually your best bet. 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.

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.
