Cranston solar in a nutshell, updated for 2026
Yes, solar is worth it for most Cranston homes: at Rhode Island’s 29.91 cents per kWh, a typical 6 kW roof offsets about $2,340 a year and pays back in roughly 8 to 9 years.
Cranston sits in Rhode Island Energy territory, and the state gives you one real fork in the road: you enroll a home system in net metering or in the Renewable Energy Growth (REG) program, not both. According to MySolarFY’s analysis (July 2026), a typical 6 kW rooftop system in Cranston makes about 7,831 kWh a year (PVWatts, ZIP 02920), which offsets roughly $2,340 a year at Rhode Island’s 29.91 cents per kWh residential rate, so a cash system at today’s installed prices pays for itself in about 8 to 9 years before any state grant. The 30 percent federal homeowner credit ended after December 31, 2025.
The numbers behind Cranston solar (2026)
- Rhode Island’s residential electricity averages 29.91 cents per kWh, as of March 2026 (EIA), well above the national average, which is the main reason a Cranston roof pays.
- A 6 kW Cranston system makes about 7,831 kWh a year in ZIP 02920 (NREL PVWatts, 2026), a real modeled run rather than a national guess.
- That offsets roughly $2,340 a year at the state rate (MySolarFY estimate, July 2026), the value your net-metering credits are built on.
- Estimated simple payback is about 8 to 9 years for a cash system before any Renewable Energy Fund grant (MySolarFY estimate, July 2026).
- Your utility is Rhode Island Energy, the former National Grid Rhode Island, which administers both net metering and the REG program in Cranston (RI OER, 2026).
Why Cranston electric rates make solar worth it
Solar pays in Cranston because the power it replaces is expensive. Rhode Island residential electricity averages about 29.91 cents per kWh (EIA, as of March 2026), one of the higher rates in the country, so every kilowatt-hour your roof makes is one you do not buy from the grid at that price. A Cranston home spending $150 or more a month on electricity is a strong candidate. Rhode Island splits your bill into a supply charge and a delivery charge, and you can shop the supply portion, but that choice does not change how solar or net metering works, because Rhode Island Energy still owns the wires and runs the credit.
Your production is what turns that high rate into savings. A well-placed Cranston roof gets a solar resource typical of southern New England, about 4.74 peak sun hours a day, and a 6 kW system models to roughly 7,831 kWh a year for ZIP 02920 (NREL PVWatts, 2026). Output depends on your roof’s pitch, shading, and orientation, so estimate your own roof with NREL’s free PVWatts calculator rather than a generic figure. The table below scales that modeled run to a few common system sizes so you can see the range.
Estimated Cranston production and bill offset by system size
This is our own estimate for Cranston, computed from the real PVWatts run for ZIP 02920 (about 1,305 kWh per kW per year) times the EIA Rhode Island residential rate of 29.91 cents per kWh. It assumes the net-metering path, a flat rate, and no incentives, so treat it as a planning estimate, not a quote. Real savings are usually higher because electricity rates tend to rise over time.
| System size | Est. annual production | Est. annual bill offset | Est. 25-year bill offset |
|---|---|---|---|
| 5 kW | about 6,526 kWh | about $1,950 | about $48,800 |
| 6 kW | about 7,831 kWh | about $2,340 | about $58,600 |
| 8 kW | about 10,441 kWh | about $3,120 | about $78,100 |
| 10 kW | about 13,052 kWh | about $3,900 | about $97,600 |
Inputs: PVWatts v8 modeled 6 kW = 7,831 kWh/year for ZIP 02920 (NREL, 2026), scaled linearly; 29.91 cents per kWh (EIA, March 2026). Estimate only; your roof, usage, and the current rate will differ.

Your Cranston utility is Rhode Island Energy, not National Grid
A lot of Cranston homeowners still call the electric company National Grid, but the name changed. Rhode Island Energy is the electric utility for Cranston and for almost all of Rhode Island. It is the former National Grid Rhode Island electric business, legally the Narragansett Electric Company, which PPL Corporation acquired and rebranded as Rhode Island Energy in 2022 (U.S. DOE Alternative Fuels Data Center; Rhode Island Energy, as of 2026). National Grid no longer serves Rhode Island electric customers, so if you read an older solar guide that says “National Grid,” it means the same wires you are on today.
Why it matters for solar: Rhode Island Energy runs your net metering and your REG contract. Whichever compensation path you choose, Rhode Island Energy is the utility that interconnects your system, meters your exports, and pays or credits you. For the statewide mechanics behind that, see our Rhode Island Energy net metering and interconnection guide and the broader Rhode Island solar guide.
Net metering or REG: the Rhode Island decision you have to make
Here is the fork that makes Rhode Island different from most states: you pick one program, not both. Rhode Island’s Office of Energy Resources spells out two solar compensation paths, and a home system enrolls in one of them, not both at once (RI OER, as of 2026).
- Net metering credits your Rhode Island Energy bill for the power your panels send to the grid, so a system sized close to your yearly usage can wipe out most of your electric bill (RI OER net metering, as of 2026).
- The Renewable Energy Growth (REG) program is a fixed-price contract instead: you sell your system’s output to Rhode Island Energy at a set per-kWh ceiling price for a residential term of 15 or 20 years, and you keep buying your own power at the retail rate. The ceiling price is reset every program year by the state’s Distributed Generation Contracts Board, so confirm the current figure before you decide (RI OER REG program, as of 2026).
Note: Do not let an installer pick this for you on autopilot. Net metering tends to suit a homeowner who wants to zero out their own bill, while REG is a production contract that pays on every kWh you generate. The right answer depends on your usage, your roof size, and the current REG ceiling price, which changes yearly. Ask any installer to model both paths for your home with today’s numbers.
| Feature | Net metering | Renewable Energy Growth (REG) |
|---|---|---|
| How you benefit | Bill credits for exported power, offsetting your own usage | A fixed per-kWh payment on everything your system produces |
| Term | Ongoing while you own the system | A set contract, residential term of 15 or 20 years |
| Price certainty | Moves with the retail rate | Locked ceiling price at enrollment, reset yearly for new projects |
| Best when | You want to erase most of your electric bill | You want a predictable production payment |
| Can you combine them | No, you choose one path per system | No, you choose one path per system |
Source: RI Office of Energy Resources, as of 2026. Structure verified; the current REG ceiling price resets each program year, so confirm it before enrolling.
Rhode Island solar incentives a Cranston homeowner can stack
Beyond your net-metering or REG choice, Rhode Island layers a few more benefits, and unlike the compensation programs, most of these can stack. We keep the full statewide detail on our Rhode Island solar incentives guide; here is what applies to a Cranston account.
| Incentive | What it does | Source |
|---|---|---|
| Renewable Energy Fund (REF) grant | An upfront grant from RI Commerce that lowers your install cost, offered in limited funding rounds | RI Commerce |
| Sales-tax exemption | Rhode Island’s 7 percent sales tax does not apply to qualifying renewable-energy equipment | RIGL 44-18-30 |
| Property-tax exemption | A residential solar system does not increase your home’s assessed value for property tax | RI OER |
The Renewable Energy Fund is worth a closer look, and a phone call. The REF, run by Rhode Island Commerce, is a grant that lowers the upfront cost of a home system, paid as a per-watt amount with a cap per project (RI Commerce, as of 2026). It is not always open: funding comes in scheduled rounds, and a round closes once its budget is used, so the per-watt amount, the cap, and availability all move over time. Check the current round on the RI Commerce Renewable Energy Fund page before you count on it. The sales-tax and property-tax exemptions, by contrast, are steady statewide protections, and both are linked from the state’s own solar page.
One honest caveat: Rhode Island does not have everything other states have. There is no state personal income-tax credit for home solar, and Rhode Island does not run an SREC market the way Massachusetts once did. Instead, the REG program is the state’s production-based incentive, which is exactly why the net-metering-versus-REG choice above matters so much here.
What the ended federal tax credit means for Cranston
The federal homeowner credit is gone, but Rhode Island’s programs are not. The 30 percent federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act, so a Cranston homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS; SEIA, as of 2026). Search results and older installer pages still ask whether the 30 percent credit is going away; the accurate answer for 2026 is that the homeowner version already ended. Net metering, REG, the Renewable Energy Fund, and the state tax exemptions were not affected, and at Rhode Island’s high rates the bill offset alone is substantial. For the full picture, see what the federal solar tax credit change means in 2026.
One federal exception exists, and it is not yours to claim. A separate commercial credit, Section 48E, can apply to a leased or PPA system, but the company that owns the panels claims it, not the homeowner (IRS, as of 2026). On a lease or PPA you do not file for a federal credit yourself; the system’s owner does. The 25D homeowner credit, by contrast, ended for systems placed in service after December 31, 2025.
What a Cranston solar project actually costs and when it pays back
Cranston’s suburban housing stock is friendly to solar. Much of the city is single-family homes on standard lots in Providence County, so the typical Cranston roof is simpler to work with than a dense Providence triple-decker or a tight coastal Warwick lot. That usually means a cleaner install and fewer surprises, though an older home may still need an electrical service upgrade to carry a modern system plus a battery or EV charger. The payback below uses the same real inputs as the production table, so you can see how the price you pay per watt moves the timeline.
Estimated payback for a 6 kW Cranston system by installed price
Our estimate, for a cash purchase before any Renewable Energy Fund grant. It divides an installed cost at a few common price points by the roughly $2,340 a year that a 6 kW system offsets at Rhode Island’s rate. A REF grant, where a round is open, would shorten every figure below.
| Installed price | Gross system cost (6 kW) | Est. simple payback |
|---|---|---|
| $3.00 per watt | about $18,000 | about 7.7 years |
| $3.25 per watt | about $19,500 | about 8.3 years |
| $3.50 per watt | about $21,000 | about 9.0 years |
Inputs: 6 kW system; annual offset about $2,340 (7,831 kWh at 29.91 cents per kWh, EIA March 2026); cash purchase, flat rate, before incentives. Estimate only. Actual pricing, usage, and the current rate vary; a REF grant would shorten payback.
Cranston is also becoming a bigger name in Rhode Island solar beyond rooftops: local reporting notes the city could host one of the state’s largest solar farms, a sign of how much the grid around you is shifting toward solar (The Public’s Radio, as of 2026).
Permits and paperwork: Rhode Island’s one statewide solar form
Rhode Island makes permitting unusually uniform, which is good news for a Cranston install. Since January 1, 2018, every Rhode Island municipality has been required to use the same statewide solar permit application for all solar PV projects, rooftop or ground, regardless of size (RI OER statewide solar permit, as of 2026). So your installer files the same standardized form in Cranston that they would in Providence or Warwick, which cuts the guesswork out of local review. In Cranston, permit applications are submitted online through the city’s ViewPointCloud portal, and your installer normally handles the building and electrical permits, the Rhode Island Energy interconnection application, and the final Permission to Operate for you.
How to choose a solar installer in Cranston
Cranston homeowners can choose from local Rhode Island companies and regional installers, which means real competition on price and service. Rather than chasing a “best installer” list, screen any company against objective criteria:
- A valid Rhode Island contractor registration and the proper electrical licensing for the work.
- NABCEP certification, the industry’s professional standard for PV installers.
- A clear workmanship and equipment warranty in writing.
- Real experience with Rhode Island Energy interconnection and the statewide solar permit, so your paperwork and Permission to Operate move smoothly.
- A written production estimate, plus a side-by-side model of net metering versus REG using today’s numbers, not last year’s. To understand the credit side of that comparison, see how net metering credits your solar exports.
MySolarFY matches you with licensed installers that serve your area so you can compare real local quotes side by side, with no obligation. To see how we research and where these figures come from, read our data and methodology and how MySolarFY works.

How to pay for solar in Cranston: cash, loan, lease, or PPA
There is no single right way to pay for solar. The best fit depends on whether you want to own the system and keep the incentives yourself, or avoid an up-front cost. A lease or PPA can mean no up-front cost for eligible homeowners, but it is a long-term agreement with monthly payments, not free solar, and the system owner, not you, collects the REF grant, the REG or net-metering value, and any federal commercial credit.
| Path | Up-front cost | Who keeps the incentives | Best when |
|---|---|---|---|
| Cash purchase | Full system cost | You, the owner | You want the fastest payback and the most lifetime savings |
| Solar loan | Little to none, financed | You, the owner | You want ownership without paying cash up front |
| Lease or PPA | $0-up-front where eligible | The third-party owner | You prefer no up-front cost and a simpler, fixed monthly bill |
Frequently asked questions
Is solar worth it in Cranston, Rhode Island in 2026?
For most owner-occupied Cranston homes with decent sun, yes. Rhode Island residential electricity averages about 29.91 cents per kWh (EIA, as of March 2026), among the higher rates in the country, so every kilowatt-hour your roof makes offsets an expensive grid one. A 6 kW system models to about 7,831 kWh a year in Cranston, worth roughly $2,340 at that rate (MySolarFY estimate, July 2026), for an estimated cash payback near 8 to 9 years before any state grant. Savings depend on your roof, usage, and whether you choose net metering or REG, but the high local rate is what makes Cranston a strong solar market.
Who is my electric utility for solar in Cranston?
Rhode Island Energy. It is the former National Grid Rhode Island electric business, which PPL Corporation acquired and rebranded in 2022, so National Grid no longer serves Rhode Island electric customers (U.S. DOE AFDC, as of 2026). Rhode Island Energy interconnects your system, meters your exports, and administers both net metering and the Renewable Energy Growth program in Cranston. If an older guide says National Grid, it is the same utility under its former name.
Should I choose net metering or the REG program in Rhode Island?
You have to pick one, not both, for a given system (RI OER, as of 2026). Net metering credits your bill for exported power, which suits a homeowner who wants to erase most of their own electric bill. The Renewable Energy Growth program instead pays a fixed per-kWh price on everything your system produces for a 15 or 20 year term, with a ceiling price reset each program year. The better choice depends on your usage, your roof size, and the current REG price, so ask your installer to model both with today’s numbers before you sign.
Is there still a 30 percent solar tax credit in 2026?
Not for homeowners. The 30 percent federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act, so a Cranston homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS, as of 2026). A separate commercial credit, Section 48E, can apply to a leased or PPA system, but the company that owns the panels claims it, not the homeowner. Rhode Island’s net metering, REG, Renewable Energy Fund, and tax exemptions were not affected, so the local case still holds.
What Rhode Island incentives can I still get in Cranston?
Several. Rhode Island’s Renewable Energy Fund, run by RI Commerce, offers an upfront grant that lowers your install cost, though it comes in limited funding rounds, so check the current round (RI Commerce, as of 2026). The state also exempts qualifying solar equipment from its 7 percent sales tax (RIGL 44-18-30), and a residential solar system does not increase your home’s assessed value for property tax (RI OER). Rhode Island does not offer a state income-tax credit for home solar, and it has no SREC market; the REG program is its production incentive instead.
Do I need a special permit for solar in Cranston?
Yes, but Rhode Island keeps it simple. Since January 1, 2018, every Rhode Island city and town uses the same statewide solar permit application for all solar PV projects, so Cranston reviews the same standardized form used across the state (RI OER, as of 2026). Applications are filed online through Cranston’s ViewPointCloud portal, and your installer normally handles the building and electrical permits, the Rhode Island Energy interconnection request, and the final Permission to Operate. That uniform process is one reason a Rhode Island install tends to have less local red tape than in states where every town has its own form.
Can I get solar with no up-front cost in Cranston?
Some homeowners can, through a lease or power purchase agreement (PPA) where eligible, which can mean no out-of-pocket cost at installation in exchange for monthly payments. This is not free solar; it is a long-term agreement, typically 20 to 25 years, and total payments may exceed the cost of a cash purchase. On a lease or PPA the third-party owner, not you, collects the Renewable Energy Fund grant and the REG or net-metering value, while your benefit is a lower or fixed power price. If you want to own the system and keep those incentives, a cash purchase or solar loan is the path that captures them. Check what you qualify for before deciding.
