New Jersey's solar story in 2026 is a strong one. The state has 4.5 peak sun hours per day, electricity rates averaging $0.204/kWh, a robust TREC (Transitional Renewable Energy Certificate) program, full retail net metering, and both sales tax and property tax exemptions. There's no state income tax credit for solar — but the TREC program and high electricity rates more than compensate, pushing payback into the 8–11 year range.

Key Takeaways
- A typical 8 kW New Jersey system costs ~$22,400 at $2.80/watt (LBNL 2024) — no federal 25D credit applies in 2026
- New Jersey TREC program pays ~$90/TREC for 15 years — significantly boosting ROI for residential systems
- At $0.204/kWh (EIA 2025), New Jersey rates are among the highest in the mid-Atlantic — each solar kWh saves considerably
- Estimated payback: 8–11 years, with both sales and property tax exemptions stacking on top of TREC revenue
New Jersey Solar Costs in 2026
At $2.80/watt, New Jersey is near the national median for installation costs. An 8 kW system — right-sized for a typical New Jersey single-family home — costs approximately $22,400 before any incentives. With 4.5 peak sun hours per day, that system produces roughly 13,200 kWh annually.
At $0.204/kWh, New Jersey's electricity rate is well above the national average of $0.161/kWh. Every kWh of solar production saves $0.204 — substantially more than Midwest or Southeast states. That high rate is the foundation of New Jersey's strong solar economics.
| System Size | Cost at $2.80/W | Annual Production (4.5 hrs) | Annual Savings at $0.204/kWh |
|---|---|---|---|
| 6 kW | $16,800 | ~9,900 kWh | ~$2,020 |
| 8 kW | $22,400 | ~13,200 kWh | ~$2,693 |
| 10 kW | $28,000 | ~16,500 kWh | ~$3,366 |
New Jersey's TREC Program
New Jersey's Transitional Renewable Energy Certificate (TREC) program replaced the previous SREC program and offers a fixed incentive for 15 years per TREC (1 TREC = 1 MWh of solar production). Current TREC values for residential systems have been approximately $90 per TREC — among the highest in the mid-Atlantic region.
For an 8 kW system producing 13.2 TRECs annually:
- Annual TREC revenue: 13.2 × $90 = $1,188/year
- Over 15 years: approximately $17,820 total
Combined annual benefit in the first 15 years: electricity savings ($2,693/year) + TREC revenue ($1,188/year) = approximately $3,881/year.
At $22,400 system cost, that represents an effective payback of approximately 5.8 years during the TREC period — and after the TREC contract expires, still $2,693/year in net metering savings for the remaining panel life.
According to Lawrence Berkeley National Laboratory's Tracking the Sun 2024 report, New Jersey's TREC program combined with high electricity rates gives it payback periods that rank among the best in the Northeast for a state without a direct income tax credit.
New Jersey Tax Exemptions
New Jersey offers two permanent tax exemptions for residential solar:
Sales tax exemption: New Jersey law (N.J.S.A. 54:32B-8.39) exempts solar equipment from the state's 6.625% sales tax. On a $22,400 system, that saves approximately $1,484 on equipment costs.
Property tax exemption: New Jersey law (N.J.S.A. 54:4-3.113a) provides a 100% exemption on the added home value attributable to solar — permanently. If your solar system adds $18,000–$22,000 to your home's market value, none of that is subject to property tax assessment. New Jersey's effective property tax rate is among the highest in the nation (~2.2%), making this exemption worth approximately $400–$484/year — significant savings.
| Incentive | Authority | Estimated Value (8 kW system) |
|---|---|---|
| TREC program (15 years) | NJBPU / NJ Clean Energy Program | ~$17,820 total over 15 years |
| Sales tax exemption | N.J.S.A. 54:32B-8.39 | ~$1,484 |
| Property tax exemption | N.J.S.A. 54:4-3.113a | ~$400–$484/year ongoing |
| Full retail net metering | NJBPU net metering rules | Included in annual savings above |
Net Metering in New Jersey
New Jersey's Board of Public Utilities (NJBPU) requires PSE&G, JCP&L, Atlantic City Electric, and Rockland Electric to offer net metering for residential solar systems. Current rules provide full retail net metering — each exported kWh earns a credit at $0.204/kWh. Annual true-up applies, allowing summer surplus to offset winter bills.
New Jersey net metering reform has been discussed but full retail net metering was still in place as of 2026. Homeowners who install under current rules are expected to receive grandfathered treatment for at least 10 years from installation if policy changes.
What to Do Next
Confirm your utility and current TREC block availability.
TREC values are set periodically by NJBPU and can change with new program blocks. Your installer should confirm the current TREC rate for residential systems in your utility territory before quoting your system. The $90/TREC figure should be verified against current program terms.
Run your ROI estimate including 15 years of TREC revenue.
Any solar estimate for New Jersey that doesn’t include TREC payments will significantly understate your ROI. Confirm that any calculator or installer quote includes the full 15-year TREC payment stream in the payback calculation.
Confirm the property tax exemption is being applied.
New Jersey’s solar property tax exemption is automatic under state law — your local tax assessor should not increase your assessment due to the solar installation. If you receive a revised assessment that includes the solar added value, contact your assessor and cite N.J.S.A. 54:4-3.113a.
Get at least three competing installer quotes.
New Jersey has one of the most competitive solar installer markets in the Northeast. Multi-quote buyers save an average of 15–20% on system cost. Use EnergySage or SolarReviews to collect competing quotes without repeated sales conversations.

Bottom Line
New Jersey solar in 2026 is among the strongest mid-Atlantic cases. High electricity rates ($0.204/kWh), a robust TREC program (~$90/TREC for 15 years), full retail net metering, and both tax exemptions create a financial package that competes with states offering direct income tax credits. Payback in the 8–11 year range over a 25-year panel lifespan gives strong long-term returns.
The main risk is TREC program policy changes over the 15-year contract period. But TREC is a contracted commitment — if you're locked in at signing, you're protected.
