Average Cost of Solar Panels in New Jersey

The average cost of solar panels in New Jersey is about $3.05 per watt before incentives in 2026 — slightly above the national average, but New Jersey is one of the few states where the incentives more than make up for it. A standard 8 kW residential system runs roughly $24,400 installed. The 30% federal Investment Tax Credit (Section 25D) expired on December 31, 2025 under the One Big Beautiful Bill, so a 2026 cash or loan buyer no longer subtracts it. Yet New Jersey solar still pays back faster than almost anywhere else in the country — because the state stacks high electricity rates, 1:1 net metering, two tax exemptions, and a 15-year cash incentive on top of every panel you install.

The reason comes down to two numbers no other state pairs quite this way: New Jersey homeowners pay some of the highest power rates in the nation (around $0.23–$0.26 per kWh), and the state's SuSI / SREC-II program pays system owners about $85 for every megawatt-hour their panels generate for 15 years. This guide breaks down 2026 prices by system size, explains exactly how the SREC-II income works, walks through New Jersey's incentives and net metering, compares the major utility territories, and shows realistic payback so you can decide whether solar pencils out for your home.

New Jersey solar cost by system size (2026)

The right system size depends on your annual electricity use. The average New Jersey home uses roughly 9,000–10,000 kWh per year, so most households land on an 8–10 kW system. The table below shows typical 2026 installed prices statewide at $3.05 per watt. Because the 30% federal tax credit expired after 2025, the 2026 column is what most cash and loan buyers now pay; the final column shows what the same system cost net through 2025, when the credit still applied, so you can see the difference. New Jersey's sales-tax exemption already applies to every figure below, so there is no 6.625% sales tax stacked on top.

Figures are New Jersey averages at $3.05/watt. Real quotes vary ±15% with roof type, shading, panel brand, and installer. Adding a home battery typically adds $9,000–$15,000. The "was, with 2025 federal credit" column is shown for reference only — the 30% credit is no longer available for 2026 installations.

Methodology: New Jersey per-watt and system-cost figures (and the city-level cost/payback table below) are 2026 market averages compiled from installer quote platforms and published solar pricing reports (e.g. EnergySage and industry cost surveys) across the PSE&G, JCP&L, and Atlantic City Electric territories; peak-sun-hour and output figures use typical published regional data (e.g. NREL). SREC-II income reflects the published Successor Solar Incentive (SuSI) ADI rate (~$85/MWh for 15 years) administered by the New Jersey Board of Public Utilities, and the sales-and-use and renewable-energy property-tax exemptions reflect published New Jersey statute; the federal Section 25D credit is treated as expired for systems placed in service after 12/31/2025 per IRS/Treasury guidance under the One Big Beautiful Bill. These are planning estimates, not binding quotes — actual prices and incentive rates vary, so confirm the current ADI block with your installer and get three local quotes. Last updated June 2026.

The SuSI / SREC-II incentive — New Jersey's secret weapon

The single biggest reason solar still makes excellent financial sense in New Jersey is the state's Successor Solar Incentive (SuSI) program. For a home system, you enroll in the Administratively Determined Incentive (ADI) track, which pays a fixed $85 for every megawatt-hour (1,000 kWh) your panels generate — a payment commonly called an SREC-II — for a full 15 years. Crucially, you earn it on every kilowatt-hour your system produces, whether you use that power at home or export it to the grid.

Run the numbers on a typical 8 kW system: it generates about 9.6 MWh per year in New Jersey, so it earns roughly $816 a year in SREC-II payments — about $12,000 over the 15-year term, entirely separate from the money you save on your electric bill. A 10 kW system earns closer to $1,020 a year. This cash stream is what fills the gap left by the expired federal tax credit, and it's why New Jersey payback periods are years shorter than in states that rely on bill savings alone.

New Jersey solar cost & payback by city (2026)

New Jersey is compact and gets fairly uniform sun (about 4.0–4.2 peak sun hours per day statewide), so the main difference city to city is your utility's retail rate, which sets how much each kilowatt-hour you self-consume or export is worth. Here's how the major New Jersey markets stack up for a typical 8 kW system, with SREC-II income included in the payback math.

Payback estimates assume a solar-only system at the full 2026 installed cost (the 30% federal credit expired after December 31, 2025), current retail net metering, and 15 years of SREC-II income. Adding a battery lengthens payback slightly; pairing with an EV or anticipated rate increases shortens it.

New Jersey solar incentives in 2026

New Jersey is one of the most incentive-rich solar states in the country. With the federal credit gone, the state-level stack below is what drives the economics — and it's unusually deep.

SuSI / SREC-II production incentive

As covered above, the SuSI program's ADI track pays residential systems about $85 per MWh for 15 years — roughly $816 a year on an 8 kW system. It's the headline incentive in New Jersey and the main replacement for the lost federal credit.

Sales-and-use tax exemption

New Jersey fully exempts solar energy systems from the 6.625% state sales tax. On a $24,400 system that's roughly $1,600 you simply never pay — the exemption is applied at purchase, so the prices in this guide already reflect it.

Renewable energy property tax exemption

Solar typically raises a home's value, and in most states that means a higher property tax bill. New Jersey's renewable energy property tax exemption shields the added value of a certified solar system from local property tax assessment increases — so you capture the home-value bump without the tax increase.

Federal tax credit — expired after 2025

Through December 31, 2025, the federal Residential Clean Energy Credit (Section 25D) let homeowners deduct 30% of a system's cost — worth about $7,300 on a $24,400 system. The One Big Beautiful Bill, signed July 4, 2025, ended that credit for systems placed in service after 2025. A New Jersey system installed in 2026 with cash or a loan gets no federal credit. The reason payback here barely moved is that New Jersey's SREC-II income, high rates, and tax exemptions absorb most of the difference. (Solar leases and PPAs may still benefit from a separate business clean-energy credit through 2027, which can lower monthly payments.)

Net metering

New Jersey offers true 1:1 net metering for residential systems up to 5 MW, crediting the excess power your panels export at the full retail rate so summer overproduction offsets winter use. PSE&G, JCP&L, and Atlantic City Electric all offered it to new customers in 2026. Because New Jersey's retail rates are among the nation's highest, each exported kilowatt-hour is worth more here than almost anywhere else.

Factors that affect your New Jersey solar price

Two New Jersey homes can get very different quotes for the same nominal system size. The biggest drivers here are:

• Roof complexity: The dense, older housing stock in North Jersey often means steeper pitches, multiple roof planes, and chimneys that raise labor and may require more microinverters than a simple South Jersey ranch roof.
• Utility territory and rate: PSE&G, JCP&L, and Atlantic City Electric each set the retail rate your net-metering credits are valued at, which changes how fast a system pays back.
• Shading and tree cover: Leafy suburban lots common across New Jersey can force shade-tolerant equipment or a larger array to hit your target output.
• Battery storage: Adding a battery for nor'easter and summer-storm outage protection is usually the single largest line-item swing in a New Jersey quote.
• Panel and inverter tier: Premium high-efficiency panels cost more per watt but produce more on smaller or partly shaded roofs — and more production means more SREC-II income.
• Installer competition: New Jersey has a deep, competitive installer market, so getting three quotes routinely saves $2,000–$5,000 on the same system.

Is solar worth it in New Jersey?

For most New Jersey homeowners, yes — and more clearly so than in most of the country. The loss of the 30% federal credit after 2025 raised the upfront price, but New Jersey is uniquely insulated from that change. Its electricity rates are among the highest in the nation, so every kilowatt-hour your panels offset is worth more here; its 1:1 net metering credits exports at that same high rate; its sales- and property-tax exemptions trim both the purchase price and your future tax bill; and the SuSI/SREC-II program hands you roughly $816 a year for 15 years on a typical system. Stack those together and payback lands in the 6–9 year range — among the fastest in the US — on panels that keep producing for 25–30 years. For a homeowner planning to stay put for even a few years, New Jersey solar remains one of the strongest residential energy investments available, federal credit or not.
