Is solar worth it in New Jersey?

New Jersey gets moderate sunshine — about 4.2 peak sun hours a day — and residential electricity runs around $0.18/kWh. For a typical $150-a-month power bill, that points to roughly a 8.2-kW system costing about $24,462 — with no federal tax credit, which ended for installations completed after December 31, 2025 — paying for itself in about 13.6 years and netting on the order of $36,903 over 25 years. Your own numbers will differ — the calculator above uses your real bill.

New Jersey is a top solar state thanks to its SREC-II program, which pays you per megawatt-hour generated for years. With above-average rates, payback stays among the fastest in the Northeast even without the federal credit.

What changes the math in New Jersey

• Your electricity rate — the more you pay per kWh, the more each solar kWh saves you. New Jersey sits at about $0.18.
• Sun hours — more sun means a smaller, cheaper system covers the same usage. New Jersey averages ~4.2 hours.
• Net metering / buyback — how your utility credits power you export swings the payback; check your specific utility's current terms.
• Install cost — quotes vary by installer and roof; the calculator defaults to a typical $/watt you can override.

New Jersey: the rules that actually decide your payback

Who your utility is, and why it matters

Four investor-owned utilities cover the state: PSE&G across the densest corridor, Jersey Central Power & Light in the north and centre, Atlantic City Electric in the south, and Rockland Electric in a small northern pocket. All are regulated by the New Jersey Board of Public Utilities, so unlike Texas or Florida there is little variation in the rules depending on who serves you.

What your exported power is worth

New Jersey retains full retail net metering, which after California's and Arizona's transitions makes it one of the more favourable remaining regimes in the country. A kWh you export is credited at the price you would have paid for it, so the timing of your generation matters far less to the economics here than it does in a net-billing state.

The New Jersey incentive layer

The certificate market is the main event, and its history confuses people. The original SREC programme closed to new entrants, was bridged by the Transition Incentive, and has been succeeded by the Successor Solar Incentive (SuSI). Under SuSI a residential system earns SREC-IIs at a fixed price per megawatt-hour generated for a fixed term of years — a predictable income stream rather than the volatile traded market the old programme became. Solar equipment is also fully exempt from New Jersey sales tax, and the added value is exempt from property tax.

Battery and self-consumption

With full retail net metering the grid already functions as an efficient store of value, so a battery is not usually the way to improve payback in New Jersey. Buy one for outage resilience if that matters to you, and price it on that basis rather than on a savings claim that retail net metering has largely already delivered.

What to check on a New Jersey quote

• Confirm the system will be registered in the SuSI programme, and ask who will own the certificates — you or the installer.
• Ask for the SREC-II price per megawatt-hour and the term in years, and check that the projected income uses that fixed figure rather than historical traded SREC prices.
• Confirm the sales-tax exemption has been applied to the quote rather than charged and later reclaimed.
• Confirm net-metering enrolment with your utility and the interconnection timeline.
• If storage is being proposed, ask what it adds in savings under full retail net metering — the honest answer is usually 'little; it is for resilience'.
