New Jersey solar incentives 2026: SuSI, taxes & net metering

New Jersey’s 2026 solar incentive stack centers on the SuSI/ADI production payment — currently $85/MWh, dropping to $77/MWh (estimate; verify current rate) for systems registering on or after roughly July 27, 2026 — plus a 100% sales tax exemption, a 100% property tax exemption on added home value, and retail-rate net metering through the state’s investor-owned utilities. The federal residential tax credit expired December 31, 2025, so it contributes $0 to any system purchased in 2026. What makes New Jersey unusual is that the SuSI/ADI payment does real, ongoing work in the payback math — it isn’t a one-time break, it’s 15 years of quarterly checks tied to how much your system actually produces.

The SuSI/ADI incentive: New Jersey’s biggest solar payment

New Jersey retired its old SREC market and replaced it with the Successor Solar Incentive (SuSI) program. Residential net-metered systems fall under the Administratively Determined Incentive (ADI) track, which pays a fixed rate per megawatt-hour of production — not a market-traded credit whose price fluctuates, but a locked-in rate set by the Board of Public Utilities (BPU).

As of mid-2026, the residential ADI rate is $85/MWh (estimate; verify current rate before registering). Under the BPU’s 2026 Three-Year Review order, that rate is scheduled to step down to $77/MWh for systems that register on or after approximately July 27, 2026. Payments run for 15 years, disbursed quarterly, and don’t escalate with inflation — the rate you lock in at registration is the rate you keep for the full term.

A few mechanics matter here:

• It’s first-come, first-served. Each year the BPU sets an MW capacity block for the ADI program. Once that block fills, new registrations either wait for the next block or register at whatever rate applies then. If your installation timeline allows it, registering before the July 2026 step-down locks in the higher $85/MWh rate for all 15 years.
• It’s based on production, not export. Unlike net metering credits, which only value electricity you send back to the grid, ADI payments are calculated from your system’s total metered production — every kWh your panels generate counts toward the payment, whether you use it in the home or export it.
• It’s separate from net metering. You collect ADI payments and net metering credits simultaneously; they’re not mutually exclusive.

Check the exact rate and capacity-block status with your installer or directly through the NJ Clean Energy Program before you sign a contract — these figures shift as BPU orders take effect.

Two automatic tax breaks that reduce your net cost

Sales tax exemption on solar equipment

New Jersey exempts solar energy equipment from its 6.625% state sales tax. Panels, inverters, racking, and directly related equipment qualify; installers claim the exemption on your behalf using Form ST-4 (Exempt Use Certificate), so there’s no separate application for you to file.

On a system priced around $23,600 (estimate — see the worked example below), that exemption saves roughly $1,564 up front, reducing your net cost before you’ve generated a single kWh.

Property tax exemption on added home value

Solar panels typically raise a home’s assessed value, which in most states means a higher property tax bill. New Jersey blocks that outcome: under N.J.S.A. 54:4-3.113a, the market value your solar system adds to your home is 100% exempt from local property tax assessment, with no expiration date. You claim it by filing Form CRES with your municipal tax assessor.

If your system adds an estimated $15,000–$20,000 in home value, none of that increase shows up on your tax bill — a permanent, automatic benefit that doesn’t depend on your income or how you financed the system.

New Jersey has no state income tax credit for residential solar. These two exemptions, alongside the SuSI/ADI payments above, are the incentive stack in place of one.

What happened to the federal solar tax credit

The federal residential solar tax credit — IRC §25D — expired on December 31, 2025, eliminated under the One Big Beautiful Bill Act. For any system purchased and owned in 2026, the federal credit contributes $0. There is no carryforward provision for new 2026 purchases; only homeowners who completed installation before the expiration date can still use previously earned credit.

That’s a real shift from 2024 and 2025, when a 30% federal credit cut payback time significantly. If an installer’s proposal still shows a 30% federal credit line item for a 2026 purchase, that’s outdated — ask them to point to current law, and verify independently. Our federal solar tax credit guide walks through exactly what changed and why.

Leases and power purchase agreements (PPAs) work differently: the system stays owned by a third-party company, which may access a separate commercial credit under §48E. That can lower your monthly lease payment, but the credit never appears on your own tax return — it’s baked into the financing structure instead. If you’re weighing ownership against a lease, compare total lifetime cost carefully.

Community Solar (CSEP): the option for renters and unsuitable roofs

Not every New Jersey household can put panels on their own roof — renters, condo owners, and homes with heavy shading or structural issues need another route. That’s what the Community Solar Energy Program (CSEP) is for. Instead of owning a system, you subscribe to a share of a solar project built elsewhere in your utility territory and receive a bill credit for your share of its output.

CSEP runs on a separate incentive track from residential ADI. The developer-side incentive dropped from $80/MWh to $60/MWh for projects registering on or after March 6, 2026, alongside a 3,000 MW program expansion. What matters to you as a subscriber isn’t the developer rate directly — it’s the guaranteed minimum discount: at least 25% off the value of your credited electricity if you qualify as a low- or moderate-income subscriber, and at least 20% for everyone else. There’s no equipment to buy, no roof work, and no ADI registration on your part.

New Jersey net metering: how it works month to month

PSE&G, JCP&L, Atlantic City Electric (ACE), and Rockland Electric (RECO) — New Jersey’s four investor-owned utilities — all credit solar exports at the full retail rate. When your system produces more than you’re using at a given moment, the surplus flows to the grid and shows up as a credit on your bill. Unused credits roll forward month to month, so a strong-production month in May can offset a lower-production month in December.

The annual true-up: read this before you size your system

Once each year, on an anniversary billing date you choose when you enroll, your utility runs an annual true-up. If you’ve drawn more from the grid than you’ve sent back over the prior 12 months, you settle the difference at retail rates as usual. But if you’ve built up a surplus credit balance by that date, the utility pays out the remainder at its avoided-cost or wholesale rate — a rate that’s consistently lower than the retail price you were being credited at all year.

New Jersey doesn’t publish one uniform avoided-cost figure across all four utilities, so don’t take a specific cents-per-kWh number from a sales proposal at face value; ask the installer to show you the utility’s current tariff. What you can control is system size: designing your array close to your actual annual usage, rather than substantially oversizing it, keeps more of your production valued at the full retail rate instead of stranding it in that lower true-up bucket. The solar savings calculator lets you model different system sizes against your own usage before you commit to a proposal.

A worked example: 8 kW system in Trenton

Install an 8 kW system in Trenton, where peak sun averages an estimated 4.3 hours per day.

Gross annual production: 8 kW × 4.3 hours × 365 days = 12,556 kWh. That’s before real-world losses. Apply a standard 0.80 system performance ratio — accounting for heat, wiring, inverter conversion, and shading losses — and you get roughly 10,045 kWh/year, or about 837 kWh/month. Always ask an installer whether their production quote already reflects a performance ratio; a raw gross number overstates what you’ll actually see by 15–20%.

Installed cost (estimate): New Jersey installed pricing currently ranges from roughly $2.77 to $3.66 per watt depending on installer, equipment, and site conditions (see solar panel cost in New Jersey for current regional data). For this example, we’ll use $2.95/W — near the lower-middle of that range — putting an 8 kW system at approximately $23,600 before any exemptions (estimate).

Automatic savings applied at purchase:

• Sales tax exemption (6.625%): ~$1,564 saved
• Adjusted net cost: ~$22,036 (estimate)

Annual electricity bill savings at $0.2353/kWh (EIA, April 2026): 10,045 kWh × $0.2353 ≈ $2,364/year (estimate).

SuSI/ADI payment, assuming registration at the current $85/MWh rate: 10.045 MWh × $85 ≈ $854/year (estimate) for 15 years.

Combined first-year value: roughly $3,218/year (estimate). Simple payback: $22,036 ÷ $3,218 ≈ 6.9 years (estimate). After the 15-year ADI term ends, ongoing savings continue from bill offsets alone — around $2,364/year at today’s rate, likely higher as electricity prices rise. These figures are illustrative only; your actual cost, production, and rate will differ, and this isn’t financial or tax advice — confirm your numbers with a licensed installer and a tax professional before signing anything.

The four numbers that shift fastest — check them first

New Jersey’s incentive rules move on their own clock: BPU orders reset ADI rates, capacity blocks fill without much warning, and utility tariffs get revised outside the news cycle.

• DSIRE (dsireusa.org) carries the current, regularly updated status of every New Jersey program referenced here.
• The NJ Clean Energy Program, or your installer, can confirm the live ADI rate and remaining capacity block before you register — the July 2026 step-down date and rate come from a BPU order and can move.
• Your utility — PSE&G, JCP&L, ACE, or RECO — can confirm its current net metering tariff and avoided-cost rate; pick your true-up anniversary month deliberately rather than by default.
• A tax professional can confirm your specific situation. None of this is financial or tax advice — the federal credit’s expiration is current law as of mid-2026, but state program and local assessment details vary by municipality.

New Jersey’s stack — no federal credit, but a real 15-year production payment plus two permanent tax exemptions — runs on different math than a state leaning on the federal credit alone. Confirm the current ADI rate and your utility’s tariff before you sign, and treat every dollar figure above as an estimate until your own proposal confirms it.
