Is solar worth it in New Jersey?
Short answer for a typical New Jersey home: a reasonable payback if you'll stay put — roughly 9.5 years to break even after the 30% credit. Run your own bill through the calculator below.
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 $17,123 after the 30% federal tax credit, paying for itself in about 9.5 years and netting on the order of $44,241 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 — stacked on the federal credit and above-average rates, payback is among the fastest in the Northeast.
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.
