New Jersey has some of the best solar economics in the country right now, and that's not hyperbole. At $0.173/kWh average for electricity and a state-run certificate program that pays homeowners $1,200–$2,000 per year on top of bill savings, the math in New Jersey is genuinely stronger than most sunnier states.

Key Takeaways
- A typical 8 kW NJ system costs ~$23,200 gross in 2026 at $2.90/watt (LBNL) — no federal Section 25D credit applies
- NJ's TREC program pays $152–$198 per certificate; an 8 kW system earns 8–10 TRECs/year ($1,200–$2,000/year extra income)
- 1:1 retail net metering (NEM 2.0) is still active in NJ — every exported kWh earns a full retail credit
- No sales tax on solar equipment and no property tax increase for 15 years — two major built-in cost reductions
- With TRECs, most NJ homeowners reach payback in 7–10 years; without TRECs, 9–13 years
What Does Solar Cost in New Jersey in 2026?
New Jersey's installed solar cost sits at approximately $2.90/watt, which is below the national median and reflects a competitive, dense installer market. According to Lawrence Berkeley National Laboratory's Tracking the Sun 2024 report, NJ's per-watt pricing has remained stable as panel prices fell and labor costs held steady. That's good news for homeowners getting quotes right now.

| System Size | Gross Cost at $2.90/W | Annual Production (est.) | Typical Household Fit |
|---|---|---|---|
| 6 kW | $17,400 | ~6,600 kWh/year | Smaller home, 500–700 sq ft, low usage |
| 8 kW | $23,200 | ~8,800 kWh/year | Average NJ single-family home |
| 10 kW | $29,000 | ~11,000 kWh/year | Larger home or EV charging included |
| 12 kW | $34,800 | ~13,200 kWh/year | High-usage home, pool, or multiple EVs |
Production estimates assume 4.2–4.8 peak sun hours per day, per NREL PVWatts data for central New Jersey. The northern Shore and Highlands run toward the lower end; southern NJ near Cape May averages closer to 4.7–4.8 hours.
Note that Section 25D — the federal 30% homeowner solar tax credit — expired December 31, 2025 and cannot be claimed on 2026 installations. The numbers above are what you actually pay without it.
How Does New Jersey's TREC Program Work?
The Transition Renewable Energy Certificate (TREC) program is the centerpiece of New Jersey solar economics in 2026, and it's worth understanding in detail before you size a system or sign a contract.
[PERSONAL EXPERIENCE]: Homeowners often overlook TRECs when getting quotes because installers sometimes don't mention them upfront — but TREC income can reduce effective payback by two to three years on a typical 8 kW system.
What Is a TREC?
A TREC is a tradable certificate that proves your solar system generated 1,000 kWh of clean electricity. The NJ Board of Public Utilities administers the SuSI (Successor Solar Incentive) program, which sets TREC prices based on market segment. Residential rooftop systems currently earn $152–$198 per TREC depending on system size and whether you're in an oversupplied segment.
This is a separate income stream from net metering. Your utility credits you for exported power through net metering at the retail rate. Then, independently, each 1,000 kWh your system produces also earns one TREC — which you sell quarterly through an NJ-certified aggregator.
How Many TRECs Does an 8 kW System Generate?
An 8 kW system in New Jersey produces roughly 8,800 kWh per year. At 1,000 kWh per TREC, that's 8–10 TRECs annually (accounting for slight production variation year to year). At the current rate of $152–$198 per TREC:
- Low end: 8 TRECs × $152 = $1,216/year
- High end: 10 TRECs × $198 = $1,980/year
- Midpoint estimate: ~$1,600/year in TREC income
That income continues for 15 years under the current SuSI program structure. Over the program life, a typical 8 kW system earns $18,000–$30,000 in TREC income alone — often exceeding the system's net purchase price after bill savings are factored in.
How Do I Actually Get Paid?
You don't sell TRECs directly. Your system must be registered with the NJ BPU, and you'll work with a TREC aggregator (many installers handle this for you or refer you to a partner). Aggregators bundle and sell certificates on your behalf and remit payment quarterly. Confirm with your installer that TREC registration is included in their service — some charge a small fee, others bundle it.
[UNIQUE INSIGHT]: The TREC market replaced New Jersey's older SREC-II (Solar Renewable Energy Certificate) market after 2021. Unlike the old SREC market, which had volatile spot pricing, TREC rates are administratively set by the BPU — which means more predictable income for homeowners over the 15-year program window.
New Jersey Solar Incentives at a Glance
Even without the federal credit, New Jersey stacks multiple programs that meaningfully reduce net cost.
[INTERNAL-LINK: Is Solar Worth It in 2026? → /guides/is-solar-worth-it-2026]
| Incentive | Type | Value | Duration |
|---|---|---|---|
| SuSI / TREC Program | Ongoing certificate income | $1,200–$2,000/year (8 kW system) | 15 years from activation |
| Net Metering 2.0 (NEM 2.0) | Bill credit at full retail rate | $0.173/kWh per exported kWh | Ongoing (policy subject to future review) |
| NJ Sales Tax Exemption | Upfront cost reduction | Saves 6.625% on equipment | Permanent (NJ statute) |
| Property Tax Exemption (Added Qualified Property) | Ongoing tax savings | Solar added value excluded from assessment | 15 years from installation |
The sales tax exemption under NJ Division of Taxation rules saves approximately $1,150 on a $17,400 system (6 kW) and $1,540 on a $23,200 system (8 kW) — real money that's often invisible to homeowners reviewing quotes.
The property tax exemption is also significant. Solar adds an average of 3–4% to home value, per NREL's home value research. On a $500,000 New Jersey home, that's a $15,000–$20,000 value increase that doesn't raise your property tax bill for 15 years under the Added Qualified Property exemption.
What Does Net Metering Look Like in New Jersey?
New Jersey currently operates under NEM 2.0 — full retail 1:1 net metering for residential systems under 2 MW. This is meaningfully better than California's NEM 3.0, which slashed export rates to avoided cost (~$0.05–$0.08/kWh). In New Jersey, every kWh you send to the grid earns a credit equal to the retail rate you'd pay to buy it back.
At $0.173/kWh average (EIA Electric Power Monthly), that's a valuable credit. An 8 kW system exporting 3,000 kWh per year earns roughly $519 in net metering credits — on top of the direct consumption savings.
Which Utility Serves Your Address?
New Jersey has three major investor-owned utilities, and your utility determines some program details:
| Utility | Service Territory | NEM Rate | Notes |
|---|---|---|---|
| PSE&G (Public Service Electric & Gas) | North/Central NJ — Newark, Trenton, Camden | Full retail (NEM 2.0) | Largest NJ utility; solar processing generally smooth |
| JCP&L (Jersey Central Power & Light) | Central/North NJ — Monmouth, Ocean, Morris | Full retail (NEM 2.0) | FirstEnergy subsidiary; interconnection timelines vary |
| Atlantic City Electric (ACE) | South NJ — Atlantic, Cape May, Cumberland | Full retail (NEM 2.0) | Pepco Holdings subsidiary; southern NJ has good sun hours |
Interconnection timelines vary by utility. PSE&G generally processes residential interconnection in 4–8 weeks. JCP&L and ACE can take 6–12 weeks in some markets. Your installer should manage this process — confirm they have experience with your specific utility.
Does New Jersey Solar Pay Back Without the Federal Credit?
Yes, and it pays back faster than most homeowners expect once TRECs are included. Here's the math on an 8 kW system at $23,200 gross.
Annual financial benefit (8 kW system, NJ average):
| Benefit Source | Calculation | Annual Value |
|---|---|---|
| Direct consumption savings (70% self-use) | 6,160 kWh × $0.173/kWh | $1,066/year |
| Net metering credits (30% exported) | 2,640 kWh × $0.173/kWh | $457/year |
| TREC income (9 TRECs at $175 avg) | 9 × $175 | $1,575/year |
| Total annual benefit | ~$3,098/year |
At $23,200 gross and $3,098/year in combined savings, the simple payback is approximately 7.5 years. Strip TRECs out and that extends to 10–11 years — still workable but notably longer.
The NJ sales tax exemption effectively cuts the gross cost by $1,540, reducing the real out-of-pocket to ~$21,660 before any other credits. That brings the with-TREC payback closer to 7 years.

How Do Peak Sun Hours Affect New Jersey Payback?
New Jersey's 4.2–4.8 peak sun hours per day are lower than Arizona (6.5) or Texas (5.5), but the state's high electricity rates and TREC program compensate for what the sky doesn't provide. That's the structural advantage of NJ: the financial architecture is designed to make solar work at mid-Atlantic sun levels.
[ORIGINAL DATA]: Comparing NJ's effective solar yield against states with higher sun hours, the TREC program adds approximately $0.18/kWh of effective value on top of bill savings — bringing NJ's effective rate per solar kWh produced to roughly $0.35+/kWh. That's competitive with California's per-kWh economics even under NEM 3.0.
| Region | Peak Sun Hours/Day | 8 kW Annual Production | Estimated Payback (with TRECs) |
|---|---|---|---|
| North NJ (Bergen, Passaic, Morris) | 4.2–4.4 | ~8,300–8,700 kWh | 7.5–9 years |
| Central NJ (Middlesex, Monmouth, Mercer) | 4.4–4.6 | ~8,700–9,100 kWh | 7–8.5 years |
| Shore & South NJ (Ocean, Atlantic, Cape May) | 4.6–4.8 | ~9,100–9,500 kWh | 6.5–8 years |
Southern New Jersey benefits most from sun exposure. Cape May County homeowners with unshaded south-facing roofs can hit payback in under 7 years with TRECs factored in.
How to Get the Best Solar Quote in New Jersey
New Jersey's competitive installer market — densely populated, high solar adoption rates, plenty of contractors — generally produces tighter quotes than rural markets. Still, quote spread of 20–30% between the highest and lowest bid for the same system is common.
Three steps that consistently produce better pricing:
- Compare at least three quotes. New Jersey solar contractors must be registered with the NJ Board of Public Utilities. Verify registration before signing anything.
- Ask each installer to include TREC registration. Some include it; some charge $200–$400. It's worth paying for if not included — TREC income justifies any reasonable registration fee.
- Ask whether the installer handles interconnection. Permit and utility interconnection delays are the most common source of installation cost overruns. An installer who manages this end-to-end protects you from surprise fees.

Should You Add Battery Storage in New Jersey?
New Jersey doesn't have a TOU (time-of-use) rate structure that's as punishing as California's, so the battery economics are less dramatic here. NEM 2.0's full retail export credit means exported solar is still valuable — you don't lose much by sending it to the grid.
That said, there are two reasons NJ homeowners increasingly consider batteries. First, the Shore and coastal areas face severe weather risk, and backup power during outages has real value. Second, the NJ Clean Energy Program has occasionally offered battery incentives that stack with solar installations.
A 13.5 kWh Powerwall 3 adds approximately $10,000–$13,000 installed in New Jersey. Without a strong financial incentive (no SGIP equivalent in NJ), the payback on storage is primarily around resilience value, not bill savings. If power reliability matters to you, it's worth modeling — if pure ROI drives the decision, solar alone typically beats solar-plus-storage on payback time in NJ's current rate environment.

Bottom Line
New Jersey is one of the few states where solar economics improved meaningfully after the federal credit expired, because the state's own programs — TRECs, full retail net metering, sales tax exemption, property tax exemption — carry real weight. A typical 8 kW system costing $23,200 gross can reach payback in 7–10 years with the TREC program factored in.
The TREC program is the key variable. Make sure your installer registers your system with the NJ BPU and connects you with a TREC aggregator. If they can't explain this process clearly, that's a red flag.
