Why this number

Solar panels in New Jersey cost about $2.68 per watt — $21,440 for a typical 8 kW system — and pay back in roughly 9.2 years at the state’s 25.2¢/kWh average rate, with the 2026 federal credit at $0. Full-retail net metering is assumed; confirm with your utility.

Everything below uses New Jersey’s real average residential electricity rate (25.2¢/kWh, EIA) and a production band of about 1,260 kWh per kW per year. Both are stated openly because they are the two inputs that decide the answer. These are estimates for sanity-checking a quote, not a quote.

Why New Jersey’s payback lands where it does

New Jersey’s average held nearly flat this year at 25.2 cents per kilowatt-hour, down less than one percent from 25.32 cents in July 2025, but that stability comes at the ninth-highest rate level in the country. A solid yield of 1,260 kilowatt-hours per installed kilowatt combines with that high, steady rate to produce one of the faster paybacks in the model, at 9.2 years. Public Service Electric & Gas, the state’s largest utility with over 2 million residential customers, actually bills below the statewide average at 19.8 cents, meaning PSE&G customers are likely looking at a payback somewhat longer than 9.2 years, while Atlantic City Electric customers, paying 22.6 cents, come closer to the state figure. Full retail net metering credits exported generation at whichever rate applies locally, so in New Jersey the utility a home is on matters almost as much as the state’s headline number.

The state average hides real spreads between utilities. The largest residential utilities EIA-861 lists for New Jersey, with each one’s own average bundled residential price (2024 — revenue ÷ sales, the audited annual figure, not this month’s tariff):

Your utility decides New Jersey’s real number — the ZIP lookup finds it in three clicks; the 2024 annual utility averages above sit apart from the June-2026 monthly 25.2¢ state figure.

An 8 kW system in New Jersey, priced out

The $2.68/W used above comes from EnergySage marketplace quotes (August 2026). Those are quotes in a competitive online market, not signed contract prices.

Read that table with one caveat: $2.68/W is New Jersey’s market average, and it is the input most likely to differ for you. A quote $0.50 per watt above or below the $2.68 used here moves the payback by roughly a year and a half in either direction.

How much sun New Jersey actually gets

A kilowatt of panels in New Jersey produces about 1,260 kWh a year on an unshaded, south-facing roof at a 20-degree pitch. Sites that swap New Jersey’s 1,260 kWh for a single national average are how Arizona and Washington end up with identical paybacks despite a 1.6x real difference in output.

That figure is a five-point cluster around New Jersey’s largest metro area, which keeps it representative of where most people actually live rather than of the state’s best site.

Two adjustments matter before you apply this to your own roof:

• Shading and orientation. The 1,260 kWh figure assumes an unobstructed south-facing array. A real New Jersey roof — its own azimuth and pitch, a tree or a chimney — typically produces 10-25% less; this page models 90% of the ideal, so the 9,072 kWh/year above is already derated from 10,080. A genuinely unshaded south roof can adjust upward in the calculator.
• Year-to-year weather moves output by roughly ±5% either way.

How New Jersey compares with the other 49

New Jersey ranks 9th of 50 on electricity price and 8th on annual output value per kW installed — close enough that its rate is a fair proxy for its solar case, which is not true everywhere. Its immediate neighbors on price are New Hampshire (26.6¢) just above and Connecticut (24.2¢) just below.

Vermont is New Jersey’s closest comparable-rate analogue — 23.8¢/kWh, roughly 1,125 kWh per kW, and a payback about 6.2 years apart (15.4 vs 9.2 years). Use it as a directional marker rather than a proxy — the gap is real.

The export question worth asking your New Jersey utility

New Jersey credits exported power at the retail rate — full net metering — under N.J.A.C. 14:8-4, so a kilowatt-hour you send to the grid is worth the same as one you buy. That is the best case for solar economics, and it is why the payback above is what it is.

It is also the assumption most likely to change. Twenty-two states have already moved to net billing. If New Jersey did the same on typical terms, this system would take about 16.2 years to pay back instead of 9.2 — 7.0 years’ difference from a policy change, with no change to the hardware. The households best placed for that day are the ones already storing their surplus, which is why what a home battery actually costs is worth knowing even while full retail holds.

⚠️ Treat this one as unconfirmed. Secondary sources only; the rule text was not verified. We could not verify it against a primary source, so check directly with your utility before relying on the figure above.

One limit worth knowing: this reflects investor-owned, state-regulated utilities; New Jersey’s municipal utilities and co-ops are exempt in most cases and set their own terms.

SRECs and what else New Jersey still offers

The 30% federal credit ended for systems completed after December 31, 2025, so it is $0 here as everywhere. What remains is state, utility and local — and it varies far more than the federal rule ever did.

SuSI / Administratively Determined Incentive — $77 per SREC-II ($77/MWh) for 15 years. The BPU order of 21 May 2026 cut this from $85 for registrations after roughly the end of July 2026 — most comparison sites still show $85. Program: NJ Clean Energy solar programs . This is paid on the electricity your system generates, separately from bill savings, so treat it as a range rather than a fixed line.

Tax exemptions

Sales tax is exempt (6.625% state rate), which keeps roughly $1,420 off the upfront cost of the system modeled here.

Property tax is fully exempt on the added value, so the system does not raise your assessment.

If that list looks thin, it is — the solar incentives hub shows which states still put real money on the table, and where New Jersey sits among them.

Is solar worth it in New Jersey at 25.2¢/kWh?

New Jersey pays because power is expensive, not because it is sunny. A 1,260 kWh/kW year is ordinary; a 25.2¢ rate is not. Every kilowatt-hour you stop buying is simply worth a lot here.

A payback under ten years also changes the timing question: once the numbers clear this comfortably, waiting has a cost of its own, and when to buy solar prices that out.

Two numbers put that in context. At New Jersey’s rate, the electricity an 8 kW system would produce is worth about $2,285 a year, so the system costs roughly 9.4 years of that output to buy outright — a simple division, before costs. The headline 9.2-year figure above is the full model: it additionally counts 2.5%/yr rate inflation, $150/yr of running costs and one inverter replacement, which is why the two differ slightly. And doing nothing is not free: 25 years of that same electricity, with rates rising at 2.5% a year, comes to about $78,050.

For a 15-year payback in New Jersey — given its sunshine rather than a national average — the electricity rate would need to be about 16.2¢/kWh. New Jersey is at 25.2¢, which is comfortably above that line.

Frequently asked questions

How we calculated this

Worked for New Jersey: 8 kW × 1,000 × $2.68/W = $21,440 gross (federal credit $0, so net before state incentives); 9,072 kWh a year × the blended kWh value at 25.2¢ retail ≈ $2,285 year-1 saving; payback ≈ $21,440 ÷ $2,285 = 9.2 years with 2.5%/yr rate growth, 0.5%/yr degradation and one inverter replacement in the 25-year model.
