Solar Panel Cost in New Jersey (2026 Estimate)

Data last updated September 10, 2026 · ranks #24 of 50 states for modeled payback

New Jersey averages about 4.3 peak sun hours a day (below the national average) with an approximate residential electricity rate near 18¢/kWh, in the mid-range nationally. In the model used here, an 8 kW system in New Jersey produces roughly 10,040 kWh a year and trims about $1,800 off annual electricity costs, paying back its net cost in about 10.4 years. That is a middle-of-the-pack payback, so whether solar is worth it in New Jersey often comes down to your specific rate, roof, and any state or utility incentives.

Estimated system cost and payback in New Jersey

Costs assume roughly $3.35/watt installed for New Jersey; the net column applies a 30% federal credit for comparison with quotes that include it. Savings and payback use the state's sun hours and rate above.

The 30% federal Residential Clean Energy Credit ended for systems paid for after December 31, 2025 under the 2025 federal budget law. Net-after-credit figures apply only if you still qualify (for example a 2025 expenditure, or a leased system where the installer passes a credit through). Confirm with a tax professional.

What moves the numbers in New Jersey

Two inputs drive most of the difference between states: how much sun a system sees and what each offset kilowatt-hour is worth. New Jersey's 4.3 sun hours set production, and its roughly 18¢/kWh rate sets what that production saves. The bigger unknowns are your roof, shading, and how your utility compensates exported power, since a lower export rate can pull real savings below the retail-rate figure above.

Net metering and export credits in New Jersey

New Jersey offers full retail net metering: exported kilowatt-hours offset imported ones at the same rate, and any monthly surplus rolls forward as a credit. At the close of a 12-month annualized period, which the customer may choose, remaining credits are paid out at the utility avoided-cost or wholesale rate, a figure much lower than retail. Sizing a system to roughly annual consumption keeps the year-end payout small and the retail-rate offset large.

Every investor-owned utility follows the same Board of Public Utilities rules, and there is no statewide capacity cap that has restricted residential enrollment. Municipal utilities in Vineland, Butler and a handful of other towns run separate programs.

New Jersey solar incentives beyond the federal credit

The Successor Solar Incentive (SuSI) program pays residential net-metered owners through its Administratively Determined Incentive track, issuing one SREC-II for each megawatt-hour produced at a fixed price for 15 years. The residential rate was set at $85 per SREC-II when the program launched in 2021; verify the current figure with the NJ Clean Energy Program, since the Board has adjusted other SuSI tiers over time. Your registration must be approved before the system is energized, so a licensed installer should handle it.

Solar equipment and installation are exempt from the state sales tax, and a residential system is exempt from property tax. Income-qualified households can pursue community solar subscriptions and the state's federally funded low-income solar initiatives, and the utilities offer on-bill or third-party financing in some territories.

Utilities and rate plans in New Jersey

PSE&G serves the densely populated corridor from Bergen County through Newark to Trenton, Jersey Central Power & Light covers the northwest and much of the Shore, Atlantic City Electric supplies the south, and Rockland Electric serves a small area near the New York line. Residential rates rose sharply in 2025 as regional capacity costs flowed through, pushing typical all-in prices above 20 cents per kilowatt-hour, which improves the solar payback. Supply can be purchased from a third-party retailer, but net metering credits are applied through the utility, and the default flat residential rate means exports are worth the same as imports at any hour.
