Key Takeaways
- Rhode Island has the 5th highest electricity rates in the nation, and Cranston homeowners pay roughly 70% more per kWh than the national average — making solar worth a serious look.
- Cranston homeowners can save an estimated $97,000 over 25 years with solar, with a typical payback period of under 8 years on a cash purchase.
- Rhode Island offers strong solar incentives — including a $5,000 state grant, net metering credits, and full sales and property tax exemptions — that meaningfully reduce the cost of going solar.
Cranston Electricity Prices
Cranston homeowners are paying some of the highest electricity rates in the country — and costs have been climbing steadily.
Rhode Island’s electricity rates rank 5th highest in the nation. From 2021 to 2024, rates rose from 22.3¢ to 28.1¢ per kWh — an increase of roughly 26%. That’s a significant jump in just three years.
Solar panels can help offset these rising costs. By generating your own electricity, you rely less on the grid. For many Cranston homeowners, that means more predictability in what they pay each month.
Over time, that predictability adds up. Solar systems typically last 25 years or more. As grid electricity costs continue to rise, the value of generating your own power in Cranston tends to grow alongside them.
Price of Energy: Rhode Island vs National Average
Cranston Area Utility Providers
In Cranston, RI, National Grid is the primary electricity provider. Based on 2023 data, National Grid’s rate is 27.2¢ per kWh — slightly above Rhode Island’s state average of 27.00¢ and significantly above the national average of 16.0¢.
As the chart shows, Cranston residents pay roughly 70% more per kWh than the national average. Rhode Island’s rates reflect higher regional grid costs, older infrastructure, and increased demand — factors largely outside a homeowner’s control.
When electricity costs this much, generating your own power at home becomes worth understanding. Solar can offset a meaningful portion of what you’d otherwise pay National Grid each month — a straightforward tradeoff many Cranston homeowners are exploring.

Rhode Island Solar Incentives
Cranston homeowners have access to several solar incentives in Rhode Island — including state grants, net metering credits, tax exemptions, and battery storage rebates — that can meaningfully reduce the cost of going solar.
Rhode Island offers a mix of financial incentives: a per-watt installation grant, an 80% retail-rate net metering credit guaranteed through 2039, a full sales tax exemption on solar equipment, a property tax exemption, and a battery storage demand response rebate.
Note that the federal residential tax credit is no longer available for new installations in 2026. State and local incentives still apply. Homeowners who lease through Palmetto’s LightReach program have the commercial ITC factored in via lower monthly payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| Renewable Energy Fund (REF) Small Scale Solar Grant | Rebate | A state grant of $0.65 per watt (up to $5,000) for residential solar installations, with an additional $2,000 adder for battery storage systems installed at the same time. | Learn More |
| Rhode Island Net Metering Program | Net Metering | Rhode Island’s net metering policy allows solar customers to earn bill credits at 80% of the retail electricity rate for excess energy exported to the grid, with protections guaranteed through 2039. | Learn More |
| Rhode Island Solar Sales Tax Exemption | Sales Tax Exemption | Rhode Island exempts all solar PV equipment and installation labor from the state’s 7% sales tax, applied automatically at the point of sale. | Learn More |
| Rhode Island Solar Property Tax Exemption | Property Tax Exemption | Rhode Island homeowners who install solar panels are exempt from any increase in property taxes resulting from the added value of their solar energy system. | Learn More |
| ConnectedSolutions Battery Demand Response Program | Rebate | Rhode Island Energy’s ConnectedSolutions program pays battery storage owners $225 per average kW performed each summer in exchange for allowing the utility to dispatch their battery during peak demand events. | Learn More |
| Affordable Solar Access Pathways (ASAP) Program | Rebate | A low-income solar lease program providing qualifying Rhode Island households in environmental justice areas access to affordable rooftop solar — currently paused and not accepting new applications. | Learn More |
Rhode Island’s Renewable Energy Fund (REF) Small Scale Solar Grant, administered by the RI Commerce Corporation, provides homeowners with a cash grant of $0.65 per watt, capped at $5,000, to help offset the upfront cost of a new solar installation. If you also install a battery storage system at the same time as your solar panels, you can receive an additional $2,000 Energy Storage Adder — regardless of how many batteries are added. Grant rounds are offered in spring, summer, and fall each year on a first-come, first-served basis, and you must apply before installation begins.
To be eligible, you must own the property in Rhode Island where the system is being installed, and the site must meet a minimum Total Solar Resource Fraction (TSRF) of 80%, verified through a shade analysis conducted by your installer. Your installer will apply for the grant on your behalf. After installation is complete and final documentation (inspection certificate, interconnection agreement, and invoices) is submitted, payment is typically processed within 6–8 weeks, with a total timeline of 6–12 months from application to check.
Important: The REF grant is only available for net-metered systems and cannot be combined with the Renewable Energy Growth (REG) Program. However, it can be stacked with the state sales tax exemption, property tax exemption, and net metering credits. Homeowners in Cranston must choose between REF + Net Metering or the REG Program — not both.
Rhode Island’s Net Metering Program allows homeowners with solar panels connected to the grid to earn bill credits for excess electricity they send to the utility. For systems installed after April 15, 2023, Rhode Island Energy (which serves approximately 95% of RI customers, including Cranston) credits exported energy at 80% of the retail rate — currently approximately $0.232/kWh. Net excess generation credits are capped at 125% of your annual utility usage. Rhode Island law protects net metering terms through 2039, giving homeowners at least 13 years of guaranteed program access for a system installed in 2026.
Net metering can be combined with the REF Small Scale Solar Grant and state tax exemptions, but it operates under a separate framework from the REG Program. Homeowners who enroll in the REG Program are not eligible for standard net metering credits on the same system. Virtual Net Metering (VNM) is also available for eligible entities such as municipalities, public schools, non-profits, and hospitals that cannot install on-site solar.
Rhode Island’s Solar Sales Tax Exemption waives the state’s 7% sales tax on all solar photovoltaic equipment and installation labor. Qualifying equipment includes solar panels, inverters, racking, wiring, solar batteries, and even electric vehicle (EV) chargers installed as part of a solar project. This exemption is applied automatically at the point of sale — no application or paperwork is required from the homeowner.
The financial savings can be significant. On a typical residential solar system, the exemption can save homeowners over $1,900, and over $2,900 if a battery storage system is also included. Because the exemption applies to labor as well as equipment, the full installed cost of the system benefits from the tax relief.
This exemption is available to all Rhode Island homeowners installing solar and/or battery storage systems, including residents of Cranston, and can be stacked with other state incentives such as the REF grant, the REG program, net metering credits, and the property tax exemption. There are no income limits or application deadlines — the benefit applies to every qualifying solar installation in the state.
Rhode Island’s Solar Property Tax Exemption ensures that homeowners who install solar panels will not see their property tax bill increase as a result of the added value that solar brings to their home. Even though solar installations typically increase a home’s market value, the assessed value used for property tax purposes excludes the value of the solar energy system entirely. This exemption applies to both primary and secondary residences across Rhode Island.
Over the lifetime of a solar system, this exemption can represent substantial savings. On average, Rhode Island homeowners save over $7,200 in property taxes thanks to this exemption. The benefit is ongoing for as long as the solar system remains on the property, making it one of the most valuable long-term incentives available to Cranston solar owners.
No special application is required to claim this exemption — it is applied automatically when your property is assessed. This incentive can be freely combined with the REF grant, REG program, net metering credits, and the sales tax exemption, making it a seamless addition to any solar incentive strategy.
The ConnectedSolutions Battery Demand Response Program, administered by Rhode Island Energy, compensates homeowners with battery storage systems for allowing the utility to draw on their stored energy during periods of peak grid demand. Participants earn $225 per average kW performed each summer. Events occur between June and September, from 3:00 PM to 8:00 PM, with a maximum of 60 events per summer and no single event lasting longer than 3 hours. The program has received regulatory approval for the 2024–2026 period.
Popular batteries such as the Tesla Powerwall and Enphase IQ 10 are eligible for the program. Homeowners can lock in their incentive rate for the first five summers of enrollment, providing predictable earnings. Importantly, customers can participate in both the ConnectedSolutions Battery Program and the ConnectedSolutions Solar Program simultaneously, and doing so will not reduce the incentives earned in either program.
Low-income customers on the A-60 rate are also eligible for a 0% interest financing loan for the cost of a battery system, with no down payment required and a $25,000 lifetime cap per account. This program can be combined with the REF Energy Storage Adder ($2,000) for homeowners in Cranston installing solar and battery together, maximizing the financial return on a battery investment.
The Affordable Solar Access Pathways (ASAP) Program, administered by the Rhode Island Office of Energy Resources (OER) and the Renewable Energy Fund, was designed to provide qualifying low-income households in environmental justice communities with access to affordable rooftop solar through an innovative solar lease. The program targets households with incomes at or below 80% of the Rhode Island median income — for example, up to $35,674 for a single person or $68,605 for a family of four. Cranston is among the eligible geographic areas for this program.
Important Notice: The ASAP program is currently paused and not accepting new applications. The OER and the Renewable Energy Fund are reviewing next steps, including whether to identify a new program vendor to continue administering the program. Interested homeowners should monitor the official program page for updates on when the program may reopen.
When active, the program also offered eligible participants access to a zero-interest HEAT loan of up to $25,000 for the installation of a battery storage system. Rhode Island remains committed to expanding solar access for low-income residents, and updates will be posted to the official program page as they become available.

Leasing Solar Panels
If you’re not ready to purchase solar panels outright, Palmetto offers an alternative through its LightReach program. In Rhode Island, Cranston homeowners served by Rhode Island Energy (formerly National Grid) are eligible for a Power Purchase Agreement (PPA) — one of the most straightforward ways to go solar with no upfront cost.
With a PPA, you pay only for the electricity your panels produce — at a set rate per kilowatt-hour (kWh) — rather than a fixed monthly amount. That means your solar bill may be a bit higher in summer when production peaks, and lower in winter. Over the course of a year, the total cost typically aligns with what a lease payment would be. You can learn more about how PPAs compare to leases here.
Compared to a cash purchase, a PPA removes the need for a large upfront investment and eliminates maintenance responsibilities — Palmetto owns the system and handles all upkeep. There’s no equipment to manage, no repair bills, and no system monitoring on your end. For many Cranston homeowners, that simplicity — combined with immediate bill savings — makes a PPA a practical path to solar.
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!

For most Cranston homeowners, solar makes strong financial sense. Rhode Island has the 5th highest electricity rates in the nation at 28.1¢/kWh — roughly 70% above the national average — and rates have risen 26% since 2021. Cranston also receives about 4.7 peak sun hours daily, supporting solid year-round production.
State incentives like a $5,000 REF grant, net metering, and full sales and property tax exemptions reduce costs further. If upfront cost is a concern, Palmetto’s LightReach lease removes that barrier entirely — no money down, with savings starting from day one.
Yes, Cranston homeowners served by Rhode Island Energy (formerly National Grid) have access to net metering. Under the standard program, excess solar energy sent to the grid is credited at 1:1 on a monthly basis, with any remaining credits rolling over month-to-month at nearly the retail rate. As of February 2024, customers can also request a cash payout or transfer credits to another account.
Rhode Island also offers a Feed-In Tariff (FIT) program, where all energy produced is credited at a fixed rate of 31¢/kWh, with payments issued monthly. Cranston homeowners should evaluate both options to determine which best fits their energy usage and financial goals.
Yes, solar panels can increase your home’s value in Cranston. Research from Zillow found that homes with solar panels sell for about 4.1% more than comparable homes without them. For a typical Cranston home, that could represent a meaningful boost in resale value.
Rhode Island’s Solar Property Tax Exemption also ensures that added home value from solar won’t raise your property tax bill — making it a win on both ends. Note that leased systems may affect this differently, as the panels are owned by the leasing company.
With Palmetto’s LightReach lease, Cranston homeowners can go solar for as little as $87–$175/month — with no upfront cost. Palmetto owns and maintains the system, so there’s nothing to manage on your end.
For those who prefer to own outright, a cash purchase typically runs $18,500–$34,500 depending on home size, with an estimated payback period of under 8 years. Note that the federal 30% tax credit is no longer available for residential cash purchases following the Big Beautiful Bill. Use the calculator above for a personalized estimate.
For Cranston homeowners, solar can be financially worthwhile — especially with a lease option. With Palmetto’s LightReach program, there’s no upfront cost. Your monthly lease payment is typically less than your current electricity bill, so savings start on day one.
Rhode Island’s electricity rates are among the highest in the nation at 28.1¢/kWh — about 70% above the national average. That gap makes solar particularly valuable here. Cash buyers can expect an estimated $97,000 in savings over 25 years with a payback period under 8 years.
