We wanted one honest number that most solar sites will not give you: how long a normal rooftop system actually takes to pay for itself, state by state, now that the 30% federal tax credit is gone. So we built the solar payback period by state for all nine Northeast states from our own data, running a real NREL production estimate against each state’s verified electricity rate. The short story is that solar still pays here, it just takes a couple of years longer than it did in 2025. Below is the full index, the exact math behind it, and what still shortens the timeline in your state.
Across the Northeast, MySolarFY estimates a typical 6 kW rooftop system now pays back in roughly 7.6 to 10.7 years in 2026, before any state incentive, now that the federal residential tax credit has ended. Payback is fastest in Massachusetts (about 7.6 years) and slowest in Pennsylvania (about 10.7 years), driven mostly by each state’s electricity rate. The expired federal credit added roughly 2 to 3 years to these timelines. State programs like New Jersey’s SuSI, Massachusetts SMART, New York’s 25% state credit, and Rhode Island’s REG or REF can pull real payback back down toward 5 to 7 years.
Key numbers behind the index (2026)
- The Northeast’s residential electricity rates run from about 20.92 cents per kWh in Pennsylvania to 30.47 cents per kWh in Connecticut, as of March 2026 (EIA).
- A standard 6 kW system produces about 7,285 to 8,065 kWh a year across these states, from a representative-city model run, as of July 2026 (NREL PVWatts v8).
- MySolarFY’s estimated 2026 payback ranges from about 7.6 years (Massachusetts) to 10.7 years (Pennsylvania), computed July 2026 at a modeled $3.00 per watt install cost with the federal credit gone.
- The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, as of January 1, 2026 (IRS), which is why 2026 payback runs longer than it did last year.
How we calculated the payback period by state
We used the same simple, transparent method for every state, so the numbers are comparable. According to MySolarFY’s analysis (July 2026), a typical 6 kW rooftop system across the nine Northeast states pays back in about 7.6 to 10.7 years in 2026, and here is exactly how we got there. We are not hiding the math, because the whole point of this index is that you can check it.
- System size: a standard 6 kW rooftop system, the same size NREL PVWatts models by default.
- Production: the real annual kWh a 6 kW system makes in a representative city in each state, from NREL PVWatts v8 (NSRDB typical-year data), as of July 2026 (NREL PVWatts).
- Electricity rate: each state’s residential average in cents per kWh, from the EIA, period March 2026 (April 2026 for Vermont) (EIA).
- Annual bill offset: production multiplied by the rate. This assumes your solar offsets power at close to the retail rate, which holds under the near-full-retail net metering that Pennsylvania, New Jersey, New York, Massachusetts, Maine, and Rhode Island still use. Connecticut, New Hampshire, and Vermont now use successor tariffs, so we flag those rows.
- Install cost: a modeled $3.00 per watt, or $18,000 for a 6 kW system, before incentives. Northeast quotes often run $3.00 to $3.50 per watt, so treat this as a mid-range estimate; a higher price stretches payback proportionally.
- Federal credit: none. The 30% federal residential credit (Section 25D) ended for systems placed in service after December 31, 2025 (IRS, as of 2026), so a 2026 cash or loan buyer cannot claim it.
- Payback: the $18,000 gross cost divided by the annual bill offset.
The 2026 Northeast solar payback index, state by state
Here is the full index, sorted from fastest payback to slowest. The pattern is clear: the states with the highest electricity rates pay back fastest, because every kilowatt-hour your roof makes offsets a more expensive one from the grid. This is our own computed estimate for a standard 6 kW system at $3.00 per watt, before any state incentive, as of July 2026.
| Rank | State | Representative city | 6 kW annual production (PVWatts) | Residential rate (EIA) | Annual bill offset | Est. 2026 payback |
|---|---|---|---|---|---|---|
| 1 | Massachusetts | Boston | 7,811 kWh | 30.21 cents/kWh | about $2,360 | about 7.6 years |
| 2 | Rhode Island | Providence | 7,762 kWh | 29.91 cents/kWh | about $2,322 | about 7.8 years |
| 3 | Connecticut* | Hartford | 7,509 kWh | 30.47 cents/kWh | about $2,288 | about 7.9 years |
| 4 | Maine | Portland | 7,911 kWh | 28.32 cents/kWh | about $2,240 | about 8.0 years |
| 5 | New York | Albany | 7,285 kWh | 28.55 cents/kWh | about $2,080 | about 8.7 years |
| 6 | New Hampshire* | Manchester | 7,551 kWh | 26.92 cents/kWh | about $2,033 | about 8.9 years |
| 7 | New Jersey | Newark | 7,833 kWh | 23.49 cents/kWh | about $1,840 | about 9.8 years |
| 8 | Vermont* | Burlington | 7,329 kWh | 24.56 cents/kWh | about $1,800 | about 10.0 years |
| 9 | Pennsylvania | Philadelphia | 8,065 kWh | 20.92 cents/kWh | about $1,687 | about 10.7 years |
Rates are EIA residential state averages for March 2026, except Vermont (April 2026) (EIA). Production is NREL PVWatts v8 for one representative-city ZIP per state: Philadelphia 19107, Newark 07102, Albany 12203, Boston 02108, Hartford 06103, Portland 04101, Manchester 03101, Burlington 05401, and Providence 02903 (NREL PVWatts). Because production varies within a state (roughly 10 to 15 percent between a sunnier and a shadier part of the same state, for example Buffalo versus Albany or Pittsburgh versus Philadelphia), treat each row as a state benchmark and estimate your own roof with the free PVWatts calculator. Payback is MySolarFY’s own estimate and excludes state incentives. Rows marked with an asterisk (Connecticut, New Hampshire, Vermont) use a successor tariff rather than 1:1 net metering, so real value can differ from a straight retail offset (see below).

Why solar payback got longer in 2026
The single biggest change to solar payback this year was not the panels, it was the tax code. The 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act (IRS; SEIA, as of 2026). In 2025, that credit knocked $5,400 off an $18,000 system, cutting the net cost to $12,600. In 2026 a homeowner who buys with cash or a loan pays the full $18,000 and cannot claim that federal credit. The bill offset that pays the system back did not change, so the payback period simply got longer.
Across the Northeast, that works out to roughly two to three added years. The table below puts the 2025 payback (with the 30% credit) next to the 2026 payback (without it), using the same 6 kW system and the same annual offset for each state. It is the clearest way to see what the federal change actually cost a homeowner.
| State | 2025 payback (with the 30% credit, net $12,600) | 2026 payback (credit ended, $18,000) | Added years in 2026 |
|---|---|---|---|
| Massachusetts | about 5.3 years | about 7.6 years | about +2.3 |
| Rhode Island | about 5.4 years | about 7.8 years | about +2.4 |
| Connecticut | about 5.5 years | about 7.9 years | about +2.4 |
| Maine | about 5.6 years | about 8.0 years | about +2.4 |
| New York | about 6.1 years | about 8.7 years | about +2.6 |
| New Hampshire | about 6.2 years | about 8.9 years | about +2.7 |
| New Jersey | about 6.8 years | about 9.8 years | about +3.0 |
| Vermont | about 7.0 years | about 10.0 years | about +3.0 |
| Pennsylvania | about 7.5 years | about 10.7 years | about +3.2 |
One nuance worth stating plainly: a separate federal credit still exists, but it is not yours to claim. Section 48E is a commercial clean-electricity credit, claimed by the business that owns a leased or power-purchase-agreement (PPA) system, never by the homeowner (IRS Clean Electricity Investment Credit, as of 2026). A homeowner who buys their own system with cash or a loan in 2026 gets no federal credit at all, because the residential Section 25D credit ended for systems placed in service after December 31, 2025. For the full picture, see what the federal solar tax credit change means in 2026 and how to think about solar without the federal tax credit.
What still shortens payback in your state
The headline index is deliberately conservative, because state programs are where the Northeast still shines. Below is what each state actually offers a homeowner in 2026, with the primary source and, for the strongest programs, our own worked estimate of what it does to payback. These programs go to the system owner, so on a lease or PPA the company that owns the panels keeps them.
| State | Net metering in 2026 | Headline state incentive (2026) | Source |
|---|---|---|---|
| Massachusetts | Near full retail; residential up to 25 kW is cap-exempt | SMART 3.0 pays about $0.03/kWh to the owner (about $0.06 low-income), plus a 15% state income-tax credit capped at $1,000 | Mass.gov SMART |
| New York | Full retail 1:1 for residential up to 25 kW, locked 20 years | A 25% New York State solar tax credit, capped at $5,000 (Form IT-255), plus NY-Sun where blocks remain open | NYSERDA; NY Tax IT-255 |
| New Jersey | Full retail 1:1 under NJ BPU rules | SuSI (SREC-II) production payment of about $90 per 1,000 kWh for roughly 15 years | NJ BPU |
| Rhode Island | Standard net metering retained (about retail value) | Renewable Energy Growth (REG) tariff with a small-solar ceiling near 30 to 34 cents/kWh in the 2024 to 2025 program year (the ceiling resets annually; confirm the current one), for a 15 to 20 year term, or a Renewable Energy Fund (REF) grant of $1.65/W (the two are mutually exclusive) | RI Office of Energy Resources |
| Connecticut | Successor tariff (RRES): choose Netting or Buy-All, administered by PURA | Buy-All pays a fixed rate for a 20-year term, set annually by PURA (recently near retail, about 32 cents/kWh for 2024 projects; confirm the current rate); Netting keeps a retail export credit with a per-kWh charge | CT PURA RRES |
| Maine | Net Energy Billing; residential rooftop still gets full retail kWh credits | No state cash rebate or income-tax credit; the value is the favorable retail NEB credit itself | Maine PUC |
| New Hampshire | Successor net metering: full credit on supply, reduced credit on distribution | A state rebate of $0.20/W, capped at the lesser of $1,000 or 30% of cost (no state income tax on wages) | NH Dept. of Energy |
| Vermont | Net metering under PUC Rule 5.100, with REC and siting adjustors | A net-metering adder of roughly $0.01 to $0.03/kWh (confirm the current PUC value); no state income-tax credit | VT PUC |
| Pennsylvania | Full retail 1:1 net metering; no successor tariff | A merchant SREC market only, with a market-set price (no state-fixed value); confirm the current spot price | PA PUC; DSIRE |
A few worked examples show how much these programs move the needle. In New Jersey, SuSI pays about $90 for every 1,000 kWh, so our modeled 7,833 kWh Newark system earns roughly $705 a year for about 15 years; stacked on the bill offset, that pulls estimated payback from about 9.8 years down to around 7 years (MySolarFY estimate, July 2026). In New York, the 25% state tax credit trims roughly $4,500 off a modeled $18,000 system, cutting estimated payback from about 8.7 years to about 6.5 years, the biggest incentive cushion of any state in the index. In Rhode Island, a REF grant near the $5,000 cap can drop estimated payback to under 6 years. In Massachusetts, SMART adds about $234 a year on our Boston model, moving payback from about 7.6 years toward roughly 7 years. These are estimates, not quotes, and the program values reset on regulatory cycles, so confirm the current figure before you budget. For the deeper state rules, start with your state hub below.

How to read this index for your own home
Treat the index as a starting line, not a quote. Three things move your real payback off the table number, and all three are worth checking before you decide.
- Your rate is not the state average. The EIA figure is a statewide residential average; your own utility, rate class, and time-of-use plan can sit above or below it, and rates reset on utility cycles. Read the supply and delivery lines on your actual bill.
- Your roof is not the model roof. Pitch, orientation, and shading can swing production well above or below a 6 kW representative-city estimate. Estimate your specific roof with NREL’s free PVWatts calculator before you size a system.
- Your net-metering rules may be a successor tariff. In Connecticut, New Hampshire, and Vermont, exports are not credited at a flat retail rate, so the value of a kilowatt-hour you send back differs from the bill offset in our index. Ask any installer to model your state’s current tariff.
Because it is a living data asset, we re-run this index when the underlying rates and programs change; the rates here are dated to their EIA period and the programs to July 2026. For how these savings compound over the life of a system, see how much you can save with solar and whether solar panels are worth it as a financial decision.

Paying for solar in 2026 without the federal credit
Buying solar in 2026 changes the math, not the menu of ways to pay. You can still buy with cash for the fastest payback and the most lifetime savings, finance with a solar loan to own the system without paying up front, or use a lease or PPA for no up-front cost where you qualify. A lease or PPA is a long-term agreement with monthly payments, not free solar, and on those the company that owns the panels keeps the state incentives while you get a lower or fixed power price. The table below lays out the trade-offs at a high level.
| Path | Up-front cost | Who keeps state 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 |
To see which programs and financing you actually qualify for, the fastest path is to check your address and compare real quotes from licensed installers who serve your area. For the full inputs behind this index, see our data and methodology.
Frequently asked questions
What is the solar payback period by state in the Northeast in 2026?
MySolarFY estimates a typical 6 kW rooftop system pays back in about 7.6 to 10.7 years across the nine Northeast states in 2026, before any state incentive, computed July 2026 from EIA residential rates and NREL PVWatts production at a modeled $3.00 per watt. Massachusetts is fastest at about 7.6 years and Pennsylvania is slowest at about 10.7 years, mostly because Massachusetts electricity costs more per kWh. State programs such as New Jersey SuSI, Massachusetts SMART, New York’s 25% state credit, and Rhode Island’s REG or REF can shorten real payback toward 5 to 7 years. These are estimates and vary with your roof, rate, and price.
Which Northeast state has the fastest solar payback and the best incentives?
On the pure rate-driven index, Massachusetts, Rhode Island, and Connecticut have the fastest payback because they have the highest electricity rates, as of March 2026 (EIA). On incentives, the strongest homeowner programs in 2026 are New York’s 25% state tax credit capped at $5,000, New Jersey’s SuSI production payments near $90 per 1,000 kWh, Massachusetts SMART plus its state credit, and Rhode Island’s REG tariff or REF grant. There is no single winner: the best state for you depends on whether your value comes from a high electricity rate, a state tax credit, or a production incentive.
Why did solar payback get longer in 2026?
Because the 30% federal Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025 (IRS, as of 2026). That credit used to cut an $18,000 system to $12,600, so removing it raised the net cost a homeowner has to earn back. The annual savings did not change, so payback stretched by roughly two to three years across the Northeast in our model. State net metering and incentives were not affected, which is why solar still pays here, just on a longer timeline than in 2025.
Is the 30% federal solar tax credit gone?
Yes, for homeowners who buy their own system. The federal Residential Clean Energy Credit (Section 25D) ended for expenditures on systems placed in service after December 31, 2025, so a homeowner installing solar in 2026 with cash or a loan cannot claim that 30% federal credit (IRS, as of 2026). A separate commercial credit, Section 48E, can apply to leased and PPA systems, but the business that owns the system claims it, not the homeowner. State incentives, net metering, and lease or PPA financing may still be available. MySolarFY does not provide tax advice; confirm your situation with a tax professional.
What is a reasonable payback period for solar?
For the Northeast in 2026, a reasonable payback is roughly 7 to 11 years before state incentives, and often 5 to 7 years once a state program applies, based on MySolarFY’s July 2026 index. A shorter payback comes from a higher electricity rate, a strong state incentive, good sun and roof orientation, and a competitive install price. Because a quality system typically carries a 25-year performance warranty, a payback in the single digits to low teens still leaves many years of largely free electricity after the system has paid for itself. Savings are estimates and are not guaranteed.
How do I calculate my own solar payback period?
Divide your net system cost by your annual electricity savings. Net cost is the installed price minus any incentives you personally receive; in 2026 that no longer includes the federal residential credit, which ended December 31, 2025 (IRS, as of 2026). Annual savings is your yearly production in kWh times your electricity rate, plus any per-kWh state incentive you receive. Estimate your production with NREL’s free PVWatts calculator and use your actual bill for the rate. The fastest way to get real numbers is to check your address and compare quotes from licensed installers.
Do solar panels actually pay for themselves in the Northeast?
For most owner-occupied Northeast homes with decent sun, yes, they just take longer than in 2025. Our 2026 index shows a typical 6 kW system paying back in about 7.6 to 10.7 years before incentives, and often faster once a state program applies. High electricity rates are what make the region work: even the slowest state, Pennsylvania at about 10.7 years, still leaves well over a decade of largely free power under a 25-year warranty. Payback is not guaranteed and depends on your rate, roof, usage, and how you pay, so run your own numbers before deciding.
