    Sunrun’s installation process starts with an analysis of your past electricity bills to estimate your energy needs. Next, representatives assess your roof’s unique conditions — such as shading, pitch and sun exposure — to create the optimal system design for your home.

    We also like that Sunrun’s solar lease program lets you go solar without a huge upfront investment. With leases, Sunrun owns the system, and you pay a fixed monthly fee to use it. 

    What to consider: Some customers have reported dissatisfaction with contract terms. So, we think it’s important to review agreements closely before signing anything.

    Simplify your search

    Switch to solar with a system built for you.

      If you've been thinking about going solar in Rhode Island but aren’t sure where to start, you’re not alone. This guide will help you compare your options and get the best deal.

      Key insights

      In Rhode Island, a typical residential solar panel system costs $10,396 to $29,994, depending on the size of your system and what financial incentives you qualify for.

      Jump to insight

      The federal solar tax credit expires soon. You have until Dec. 31, 2025, to install a system and get the 30% solar tax credit.

      Jump to insight

      Solar panels are a long-term investment. That means choosing the right installer is just as important as choosing the right equipment.

      How to choose a solar company in Rhode Island

      In our experience, the best solar energy companies have a few things in common: great reviews, transparent contracts, reliable equipment and comprehensive warranties.

      1. Research companies

      Rhode Island has an easy-to-navigate database where you can verify contractors by seeing who’s currently licensed. The site also details any enforcement actions that have been taken against those registered as solar panel contractors.

      Solar panels typically last 25 to 30 years.

      Local experience matters, too. Companies with a history in Rhode Island understand state-specific incentive programs, utility rules, permitting requirements and how to design systems that perform well in every season.

      2. Read reviews

      Look at reviews on platforms like ConsumerAffairs, Better Business Bureau and solar-specific forums to see real customer experiences. Watch out for these red flags:

      • Equipment failures that aren’t resolved quickly
      • Misleading sales tactics about costs or savings
      • Billing and contract issues

      3. Check credentials

      Contractors need a couple of certifications before they can install solar panel systems in Rhode Island: They must be a licensed general contractor and have a Renewable Energy Professional Certificate from the Department of Labor and Training. Confirm your installer also has:

      • Insurance coverage to protect your home during installation
      • NABCEP certification (the North American Board of Certified Energy Practitioners is a respected national credential for solar installers)

      4. Compare quotes

      Get at least three solar quotes to compare prices, equipment, warranties and services. Be cautious of unusually low bids — they may signal poor-quality panels, hidden fees or weak warranty coverage.

      Consider whether you want a solar storage battery, electric vehicle (EV) charger or a monitoring system to ensure optimal output. It’s also smart to ask about critter guards in most parts of Rhode Island.

      5. Read the fine print

      The contract should be easy to understand. If anything about payment schedules, warranties, monitoring services or system maintenance doesn’t make sense — ask for clarification.

      How much does it cost to go solar in Rhode Island?

      Average solar panel costs in Rhode Island typically range between $10,396 and $29,994.

      The size of your system and whether you want a storage battery are the biggest cost factors. Adding a solar storage battery costs an extra $7,000 to $18,000.

      Most installers set the price according to the system's wattage, with a typical cost between $2.50 and $5 per watt. In Rhode Island, the average cost per watt is $3.00.

      Solar incentives in Rhode Island

      With the federal solar investment tax credit (ITC) expiring soon, it makes sense to take advantage of as many local incentives as possible.

      Residents may qualify for several solar incentives in Rhode Island, including:

      • Sales and property tax exemptions: Solar equipment is exempt from state sales tax, and the added value of a solar system won’t increase your property taxes.
      • Renewable Energy Growth (REG) Program: This program provides performance-based payments to homeowners for the electricity their solar panels generate.
      • Solar grants: Some homeowners may be eligible for state or utility grants that lower upfront installation costs.

      Are solar panels worth it in Rhode Island?

      With energy costs continuing to rise, more Rhode Island homeowners find solar power is financially worth it in the long run. The Ocean State has relatively high residential electricity rates. So, your savings go further compared with the national average.

      Homeowners with solar panels typically save $20,000 to $90,000 over 25 years.

      Like many residents, Elliott in Providence “was trying to lower my electric bill and help out the environment at the same time.”

      Everything has run smoothly since Elliott’s installation was completed. Similarly, Nancy in Jamestown said her utility bill “has been cut a lot.” 

      But it doesn’t work out for everyone. We’ve also heard about problems with leaks and roof damage. As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar.

      Still, as long as your house is a good candidate for it, solar is worth considering in Rhode Island. On average, Rhode Islanders with solar panels can avoid $106,356 in total utility costs over 25 years.

      FAQ

      How can I pay for solar panel installation?

      Getting solar panels is like buying a car. You could pay cash, but many finance instead. A solar loan works like most other types of loans. There is an application process, and you pay it back over time with interest.

      Leasing solar equipment is an attractive option for people who don’t want to get a loan or be responsible for maintaining a system.

      In general, monthly lease payments can seem cheaper at first but add up over the long run, sometimes costing more than buying the system outright.

      Do I have to get solar panels in Rhode Island?

      No. In April 2023, a state lawmaker proposed a bill that would have required rooftop solar on all new single-family homes, multi-family residential buildings and parking lots. It did not pass, but it has been sent for further study by legislators.

      How do I know if my house is a good candidate for solar?

      Plenty of unshaded roof space that faces south or west is best for optimal sun exposure. Rhode Island averages three to four peak sun hours each day. However, if you have a lot of shading around your house, they might not get enough sun to power your home. It’s also smart to upgrade any old, inefficient appliances first.

      Can I get free solar panels in Rhode Island?

      We are not aware of any legitimate programs for free solar panels in Rhode Island. However, you can lease a solar energy system with little to no upfront costs. Just look out for scams that promise free solar panels — they can cost you quite a bit of money.
