In New Jersey, an 8 kW home solar system typically costs about $20,800 to $24,800 before incentives, roughly $2.60 to $3.10 per watt. MySolarFY’s model puts the payback near 7 to 9 years, because New Jersey stacks full-retail net metering on 23.49 cents per kWh power with 15 years of SREC-II income. The 30% federal homeowner credit ended after December 31, 2025, so 2026 buyers cannot claim it.
New Jersey homeowners pay about 23.49 cents per kWh for electricity (EIA retail sales, residential NJ, as of March 2026), among the highest rates in the country. That high rate, plus 15 years of state SREC-II income, is what makes the payback math in New Jersey stronger than the national average. This page shows what an 8 kW system actually costs here, walks through our dated New Jersey payback model, and shows the inputs so you can check the numbers against your own bill. For how much solar costs nationally, see how much solar panels cost across the country; this page is the New Jersey-specific version of that math.
How much do solar panels cost in New Jersey?
Budget about $2.60 to $3.10 per watt installed for residential solar in New Jersey in 2026. For a common 8 kW system, that works out to roughly $20,800 to $24,800 before incentives, with a representative price near $22,800 at about $2.85 per watt. Your exact number depends on the equipment, roof complexity, and installer, which is why comparing more than one written quote matters (marketplace averages via SolarReviews and EnergySage New Jersey). New Jersey also waives its 6.625% sales tax on solar equipment, so that price is not padded with state sales tax (N.J.S.A. 54:32B-8.33).
According to MySolarFY’s model (August 2026), a cash-bought 8 kW New Jersey system producing about 10,400 kWh a year returns roughly $3,250 in combined bill offset and SREC-II income in year one, which puts a typical cash payback near 7 years and most homes in a 7 to 9 year range. The inputs and math are shown below so you can rerun them with your own numbers.
The New Jersey payback math, step by step
New Jersey is unusual because two things pay you at once: net-metering bill credits and SREC-II production income. Our model combines both. Here are the exact inputs we used.
| Input | Value we used | Source |
|---|---|---|
| System size | 8 kW (a typical NJ home system) | MySolarFY model assumption |
| Gross cost | About $22,800 (at ~$2.85/W; range $20,800 to $24,800) | SolarReviews, EnergySage NJ market averages |
| Annual production | About 10,400 kWh/year (10,444 kWh modeled) | NREL PVWatts v8, 8 kW, Newark 07102, TMY |
| Electricity rate | 23.49 cents/kWh (full-retail net metering) | EIA, residential NJ, March 2026 |
| SREC-II value | $77 per SREC-II (per MWh), 15 years, owner only | NJ Clean Energy Program, SolarReviews |
| Federal 25D credit | $0 (ended December 31, 2025) | IRS, SEIA |
Year-one value, the two streams added together:
- Bill offset from net metering: 10,400 kWh offset at 23.49 cents = about $2,450 a year. New Jersey still credits exports 1:1 at the full retail rate, so as long as your home uses at least what the roof makes, nearly every kilowatt-hour offsets grid power at retail price (PSE&G net metering).
- SREC-II income: 10,400 kWh is about 10.4 megawatt-hours, so the system earns roughly 10 SREC-IIs a year at $77 each, about $800 a year, paid for 15 years and only to the system owner (NJCEP).
Combined, that is about $3,250 in year one. Divide the roughly $22,800 gross cost by that yearly value and you get a simple payback near 7 years. Push the price to $24,800 or use a shadier, lower-production roof and the payback drifts toward 8 or 9 years, which is why we quote a 7 to 9 year range rather than a single number. Savings are not guaranteed; your roof, usage, utility, and financing all move the result, so get a written production estimate before you decide.
About the SREC-II figure: New Jersey’s Board of Public Utilities set the residential SREC-II incentive at $85 per MWh, then ordered a step-down to $77 per MWh for systems registered on or after July 27, 2026, again locked for 15 years (NJCEP; SolarReviews). Because a system you buy today registers after that date, our model uses the current $77 value. Systems already registered before July 27, 2026 keep the older $85 rate. Confirm the current amount with the NJ Clean Energy Program before you sign, and ask a tax professional about your situation. MySolarFY does not provide tax advice.

How you pay changes the payback, and who keeps the SREC-II income
The payback above assumes you own the system with cash. How you finance it changes both the up-front cost and who collects the SREC-II payments, which is the most misunderstood line in a New Jersey solar quote.
| How you pay | Up-front cost | Who keeps SREC-II income | Effect on payback |
|---|---|---|---|
| Cash | Full price (about $22,800) | You | Fastest payback, about 7 to 9 years |
| Solar loan | Little or none, financed over time | You | Interest extends it, but you keep both income streams |
| Lease or PPA | $0-up-front where you qualify | The third-party owner keeps it | No payback to calculate; you pay a lower or fixed power price instead |
If you own the system through cash or a loan, you keep the SREC-II income and the tax exemptions, and the payback math on this page applies. If you lease or sign a PPA, the company that owns the panels keeps the SREC-II payments, and your benefit is a lower or fixed power price with no up-front cost rather than a payback you calculate. Neither path gives a 2026 New Jersey homeowner the federal residential credit, since that credit ended after December 31, 2025. To weigh a $0 down option against buying, see no upfront cost solar in New Jersey, and for how the state incentives fit together, read the New Jersey solar incentives guide.
Why the payback is faster in New Jersey than most states
Two levers do it: a high electricity rate and 15 years of SREC-II income. At 23.49 cents per kWh, every kilowatt-hour your roof offsets is worth more here than in a cheap-power state, and the SREC-II program pays you again for the same generation. That combination is why a New Jersey payback lands years ahead of a low-rate, no-SREC state. Full-retail net metering is the third lever, since it credits exports at that same high retail rate rather than a low wholesale rate. For how the credit and SREC mechanics work in detail, read how New Jersey net metering and SRECs work and how net metering credits your solar exports. For a national payback comparison across states, see the state solar payback index for 2026.
What could change your New Jersey number
Four things move your New Jersey cost and payback the most: your roof, your utility, your usage, and the current SREC-II rate.
- Your roof. Pitch, orientation, and shade move production up or down, and production drives both your bill offset and your SREC-II count. Estimate yours with NREL’s free PVWatts calculator.
- Your utility. The retail credit that sets your net-metering value ranges roughly 21 to 30 cents per kWh across PSE&G, JCP&L, Atlantic City Electric, and Rockland Electric, so the offset half of the math shifts by utility.
- Your usage. If your home uses less than the roof makes, surplus at the annual true-up is paid at a lower wholesale rate, not retail, which trims the offset.
- The SREC-II rate. The NJ Board of Public Utilities reviews the incentive about every three years and stepped it to $77 per MWh for registrations on or after July 27, 2026, so confirm the current value before you sign.

Frequently asked questions
How much do solar panels cost in New Jersey in 2026?
Residential solar in New Jersey runs about $2.60 to $3.10 per watt installed in 2026, so a typical 8 kW system costs roughly $20,800 to $24,800 before incentives, with a representative price near $22,800 (market averages via SolarReviews and EnergySage). New Jersey waives its 6.625% sales tax on solar equipment, so state sales tax is not added on top. Your exact price depends on equipment, roof complexity, and installer, so compare more than one written quote.
What is the solar payback period in New Jersey?
MySolarFY’s model puts the cash payback near 7 years for a typical 8 kW system, with most homes in a 7 to 9 year range. The math combines about $2,450 a year in net-metering bill offset at 23.49 cents per kWh with about $800 a year in SREC-II income, roughly $3,250 in year one, against a gross cost near $22,800. A higher price or a lower-production roof pushes payback toward the top of that range. Savings are not guaranteed.
Is the federal solar tax credit part of the New Jersey payback?
No. The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a New Jersey homeowner who buys solar in 2026 with cash or a loan cannot claim it. Our payback model uses $0 for the federal credit. New Jersey’s own incentives, SREC-II income and full-retail net metering, were not affected and carry the payback on their own.
How much is New Jersey’s SREC-II worth?
The residential SREC-II incentive under the SuSI program’s Administratively Determined Incentive was $85 per megawatt-hour, and the NJ Board of Public Utilities ordered a step-down to $77 per MWh for systems registered on or after July 27, 2026, locked for 15 years. One SREC-II is earned per 1,000 kWh generated, so a typical 8 kW system earning about 10 SREC-IIs a year collects roughly $800 a year at the $77 rate, and only the system owner receives it. Confirm the current rate with the NJ Clean Energy Program before you sign.
Does leasing change the payback in New Jersey?
Yes. A lease or PPA has no up-front cost and no payback for you to calculate, because a third-party company owns the system and keeps the SREC-II income and tax exemptions; your benefit is a lower or fixed power price instead. If keeping the SREC-II income and the fastest payback matters to you, owning the system through cash or a loan is the path that captures it. See our guide to no upfront cost solar in New Jersey to weigh the options.
