Solar panel cost in New Jersey 2026: $2.95/W + SuSI income

Most states measure solar return in one currency: the electricity bill you stop paying. New Jersey adds a second one. On top of full retail net metering and an above-average 23.78¢/kWh rate (12-month EIA average through July 2026), the state’s SuSI program pays residential solar owners cash for every megawatt-hour their system produces, for 15 years — an income stream layered on top of, not instead of, the usual bill savings. Installed cost runs about $2.95 per watt, or roughly $23,600 for an 8 kW system before incentives, and that SuSI payment is a big part of why New Jersey’s solar economics rank among the strongest in the Northeast even with the federal credit gone.

SuSI (SREC-II): the piece that makes New Jersey different

SuSI stands for Successor Solar Incentive — the program that replaced New Jersey’s legacy SREC market and its transitional TREC program. Its residential piece, the Administratively Determined Incentive (ADI), issues one SREC-II certificate per megawatt-hour your system produces and pays a fixed value for 15 years, set by the New Jersey Board of Public Utilities. As of October 2026, residential net-metered systems registered on or after July 27, 2026 earn $77 per MWh; the BPU cut the value from $85 in a May 2026 order, and systems registered before that date keep $85. Energy Year 2027 registrations are open first-come, first-served until the residential capacity block fills or June 1, 2027. This isn’t a one-time rebate or a tax credit you claim once — it’s a recurring payment tied to actual production, which means a bigger system or a sunnier roof earns more every year, not just a bigger check at closing.

Get your installer to confirm your registration date and per-MWh value in writing before you sign anything, since the BPU can change the value for future registrations and you want the number locked to your contract, not a marketing brochure. Layered on top of retail-rate net metering and the state’s tax exemptions below, SuSI is the reason New Jersey solar math looks less like “save on your electric bill” and more like owning a small production asset with a bill-savings bonus attached.

What a system costs by size

The statewide installed average is $2.95 per watt in 2026 — panels, inverter, racking, electrical work, permits, and installer margin, no incentives applied yet. Most New Jersey homes land between 6 kW and 12 kW depending on usage and roof area.

Production estimated at 4.3 peak sun hours/day with an 80% system efficiency factor (inverter, heat, and wiring losses); savings at 23.78¢/kWh. All figures are estimates — get itemized quotes before making any financial decisions.

Sizing should target your 12-month kWh consumption, not your full roof area — a good installer sizes to usage, and there’s a specific financial reason to avoid overshooting it that shows up later in this guide. Model your own numbers with the solar savings calculator above.

The rate, the sun, and the price — New Jersey’s baseline case

23.78¢/kWh is meaningfully above the 18.01¢ national average, and under full retail net metering, every kilowatt-hour you produce and every kilowatt-hour you export both get valued at that same rate — which compresses payback directly. 4.3 peak sun hours a day isn’t Arizona-level, but it’s far from the bottom of the national range; a well-oriented roof in Trenton, Cherry Hill, or Parsippany produces reliably across the year, with a strong summer peak balanced against moderate winters. And the $2.95/watt installed cost benefits from a dense, competitive installer market and a relatively streamlined interconnection process, keeping prices in line with the national average rather than inflated by scarcity.

What pushes your specific quote to $2.60 or to $3.40

Equipment tier. Standard 400-watt panels cost less per watt than premium 430–450-watt high-efficiency modules. Premium panels produce more per square foot — useful on a cramped or shaded roof — at a higher upfront cost. Microinverters and power optimizers add per-panel monitoring and shade tolerance over a string inverter, at a price.

Roof complexity. A clean, south-facing single-story roof installs cheapest. Steep pitches, multiple planes, valleys, skylights, and vents mean more complicated racking and more labor hours — and New Jersey’s stock of colonial and cape cod homes means plenty of quotes carry that complexity premium.

Installer overhead and margin. The same panels from a high-volume regional company versus a smaller local shop can differ by $0.20–$0.40 per watt. Compare bids by line item — panel model and count, inverter make and model, racking, permit fees, and interconnection costs listed separately — since a single per-watt figure doesn’t tell you what you’re actually buying.

Incentives that stack with SuSI

Sales-tax exemption. New Jersey exempts solar energy equipment from its 6.625% sales tax; the purchaser documents it with an exempt-use certificate (Form ST-4), which installers typically handle. The exemption covers the equipment rather than every dollar of an installed job, and it’s generally already reflected in the installed prices in this guide — so don’t subtract it a second time from a quote.

Property-tax exemption. Solar adds measurable resale value to a home. New Jersey exempts that added value from property tax — your assessed value rises, your tax bill doesn’t — but you have to claim it: the system is certified by your local construction official, and you file Form CRES with your municipal tax assessor. Once granted, it continues for as long as the system is used for that purpose.

Federal tax credit: $0 in 2026. IRC §25D expired December 31, 2025. Don’t sign a proposal that assumes it. One partial exception: lease or PPA customers deal with a third-party owner who may still claim the commercial investment tax credit (§48E), sometimes reflected in a lower monthly payment — though that credit goes to the company, not to you.

Stack the sales-tax savings, the property-tax exemption, and 15 years of SuSI payments on top of retail-rate net metering, and New Jersey’s incentive picture holds up well against states that lost more when the federal credit expired. Full detail at solar incentives by state.

Full retail net metering — and the true-up rule that determines whether oversizing pays

New Jersey runs full retail net metering, among the most homeowner-favorable structures in the country. Surplus production flows to the grid and your utility credits it at the same 23.78¢/kWh you’d otherwise pay, with credits rolling forward month to month — a big April/May credit bank typically draws down through July and January, netting close to zero across a full year aside from the fixed monthly customer charge your utility still requires.

Several states have moved to avoided-cost crediting instead, paying only a few cents per kWh for exports, which stretches effective payback considerably. New Jersey has held the line on full retail, and that’s a major reason the numbers work here.

There’s a wrinkle, though, and it’s specific to how New Jersey structures the year. Net metering runs on a 12-month annualized period; within it, credits roll forward at full retail value, but at the end of the period — the annual true-up — any leftover surplus gets cashed out at your utility’s avoided-cost of wholesale power rate, typically just a few cents per kilowatt-hour depending on the utility and wholesale conditions at the time.

That creates two practical rules. Oversizing past your annual consumption is a losing trade, since anything stranded at the true-up gets paid wholesale pennies instead of retail 23.78¢ — size to roughly 100% of annual usage or slightly under. And New Jersey lets you choose your annualized period’s start month: starting it in early spring means the big April–June credit bank gets absorbed by summer AC load before the true-up hits, rather than being cashed out cheap. Confirm both the current avoided-cost payout and your period election with your utility — PSE&G, JCP&L, ACE, or RECO — before interconnection.

A Montclair example, worked through both incentive layers

A Montclair homeowner using 11,000 kWh a year — about $218 a month at the 23.78¢ average rate — could cover roughly 90% of that with an 8 kW system at $2.95/watt, which produces about 10,000 kWh a year at 4.3 peak sun hours and an 80% efficiency factor.

Installed cost: ~$23,600, with the sales-tax exemption already reflected in the price. Federal credit (2026): $0.

Layer one — utility savings. Net metering at 23.78¢/kWh on ~10,000 kWh produces an estimated ~$2,380 in annual savings.

Layer two — SuSI income. About 10 SREC-IIs a year at $77 per MWh (the residential value for registrations since July 27, 2026) adds roughly $770 a year for 15 years, stacked on top of layer one. SREC-II payments may count as taxable income, so ask a tax professional how they affect your return.

Utility savings alone put payback at about 10 years on these numbers; adding SuSI income brings the simple payback to roughly 7.5 years ($23,600 ÷ ~$3,150), and the property-tax exemption adds value if the home sells before the system pays for itself. Run your specific numbers through the solar savings calculator above.

Solar cost by New Jersey metro: Cherry Hill, Newark, the Shore

New Jersey is unusually uniform for solar shopping. Installed price sits near $2.95/watt statewide, and the two biggest levers — mandated full-retail net metering and 15 years of SuSI payments — apply identically everywhere in the state. What changes town to town is which utility handles your interconnection and your annual true-up.

Cherry Hill and South Jersey. A common mix-up: Cherry Hill, in Camden County, is PSE&G territory, not Atlantic City Electric — PSE&G’s footprint reaches across North, Central, and parts of South Jersey. Atlantic City Electric (ACE) serves the shore and the southernmost counties: Atlantic, Cape May, Cumberland. Check your bill to confirm, since your utility sets the avoided-cost rate on any leftover credits at your annual true-up.

North and Central Jersey. The dense Newark–Jersey City–Trenton corridor is mostly PSE&G, with JCP&L covering much of Monmouth, Ocean, and the northwest, and RECO a small pocket in the far northeast. All four utilities operate under the same state net-metering mandate, so exports are valued identically at retail during the year — the differences show up in interconnection timelines and the wholesale true-up rate, not in the core economics.

Because pricing and the core incentives barely move by location, the comparison worth making in New Jersey is between installers, not towns. Get three itemized quotes, confirm your SuSI enrollment rate in writing, and go from there. Full program detail is at New Jersey solar incentives.

Choosing an installer

Get at least three itemized quotes — panel costs, inverter costs, racking, labor, permit fees, and interconnection charges broken out separately, not folded into one bottom-line number that makes comparison guesswork.

Ask each installer to specify the exact SuSI rate you’d enroll at and to show you the enrollment process in writing — this is the piece most unique to New Jersey and the one worth the most scrutiny. Ask whether the company self-installs or subcontracts, request references from jobs completed in your county in the past 12 months, and ask about interconnection timeline, since your system can’t turn on until your utility — PSE&G, JCP&L, or another local provider — approves it.

Every price and rate figure in this article reflects 2026 market data; verify the current SuSI/SREC-II rate and program availability directly with your installer and the New Jersey Board of Public Utilities before signing anything.
