How Much Do Solar Panels Cost in New Jersey in 2026?
As of mid-2026, the average solar panel cost in New Jersey is $2.80 – $3.20 per watt installed. A typical 8–9 kW residential system costs roughly $22,400 – $28,800. The 30% federal ITC expired December 31, 2025 — but New Jersey answers with one of the best remaining stacks in the country: full-retail net metering, SREC-II (SuSI) certificate income paid per MWh for 15 years, and a sales tax exemption.
New Jersey homeowners pay an average residential electricity rate near $0.18/kWh and see 4.0 – 4.7 peak sun hours per day. With SREC-II income included, simple payback typically runs 8–12 years — among the best post-credit states.

National vs New Jersey Pricing Comparison
| Metric | National Average (2026) | New Jersey Average (2026) | Notes |
|---|---|---|---|
| Cost Per Watt | $2.50 – $3.10 | $2.80 – $3.20 | Market-dependent |
| Typical System Cost | $21,000 – $28,000 | $22,400 – $28,800 | Before incentives |
| Avg. Electricity Rate | ~$0.18/kWh | ~$0.18/kWh | Near national average |
| Avg. Sun Hours/Day | 4.5 hours | 4.0 – 4.7 hours | Decent for the latitude |
| Payback Period | 10–14 years | 8–12 years | SREC-II income shortens it |
Cost Per Watt Analysis
Quotes in northern NJ metros typically fall within $2.80 – $3.20; South Jersey markets trend slightly cheaper. Dense installer competition in the NY-metro orbit keeps pricing honest.
Total System Cost for Typical Homes
| System Size | Gross Cost (2026) | Best For |
|---|---|---|
| 6 kW | $16,800 – $19,200 | Small home |
| 8 kW | $22,400 – $25,600 | Average home |
| 10 kW | $28,000 – $32,000 | Family home / EV |
| 12 kW | $33,600 – $38,400 | Large home + pool |

New Jersey Solar Incentives and Financial Benefits
- SREC-II / SuSI program: qualifying residential systems earn Solar Renewable Energy Certificates sold to the state at a set price per MWh generated, typically for 15 years — a second income stream on top of bill savings. Confirm current eligibility and enrollment windows with your installer.
- Full-retail net metering: New Jersey law credits exports at the retail rate with annual true-up — among the strongest protections in the nation.
- Sales tax exemption: solar equipment is exempt from the 6.625% state sales tax.
- Property tax: renewable systems are not assessed toward property tax increases.
With the federal credit gone, SREC-II income is what keeps New Jersey solar economics strong — treat it as the deciding factor in your quote comparison.
Payback Period and Long-Term Savings
An 8.5 kW system generating ~11,500 kWh/year at $0.18/kWh avoids roughly $2,070/year in electricity. Add SREC-II income (per-MWh payments over 15 years) and effective simple payback lands around 8–12 years for 2026 purchases. Over 25 years, cumulative savings plus certificate income can exceed $60,000 before rate escalation.
Is Solar Worth It in New Jersey in 2026?
For most homeowners with a sound roof, yes — New Jersey is one of the strongest states post-credit. Full-retail net metering plus SREC-II income replaces most of the lost federal subsidy. The key homework: confirm SREC-II availability and pricing at quote time, since program capacity is administered in tranches and terms evolve.
