Quick answer
In mid-2026, an installed residential system in New Jersey runs $2.80 – $3.20 per watt — so a typical 8–9 kW system costs $22,400 – $28,800 before any incentive. The 30% federal tax credit expired December 31, 2025 (P.L. 119-21), so 2026 buyers pay the full gross price and should treat that as the working number. What keeps New Jersey on the short list anyway is the state’s own stack: full-retail net metering, SREC-II (SuSI) certificate income paid per MWh for 15 years, a sales tax exemption, and a property tax carve-out.
New Jersey’s residential electricity rates are well above the national average — the EIA measured 24.95¢/kWh for June 2026 versus 18.34¢ nationally (source below). With SREC-II income included, simple payback typically lands around 8–12 years for 2026 purchases. Without certificate income, the same system lands in the 10–13-year range — still workable at these rates, but a very different sales pitch.
Key takeaways
- Installed cost: $2.80 – $3.20/W, or $22,400 – $28,800 for a typical 8–9 kW system. DIY installation runs ~40–60% less than installer pricing, but equipment alone still runs roughly $1.00 – $1.50/W and permitting/shaping costs are on you.
- No federal credit in 2026. The 30% ITC expired December 31, 2025. Do the math on gross cost plus state incentives — see what ended and what still helps.
- The rate is the story. EIA’s June 2026 residential average for New Jersey was 24.95¢/kWh, about 36% above the 18.34¢ U.S. average. In the worked example below, that rate alone produces ~$2,370 of electric bill savings a year on a 9 kW system.
- Export compensation is full retail — the strongest deal available in U.S. solar, per our net metering by state tracking.
- SREC-II income is the difference between 9–12-year and 12–14-year payback — and the piece you must verify at quote time (see caveats below).
- New Jersey is still one of the stronger post-credit states — you just need honest numbers, not 2025-era marketing math.
What the money looks like: per-watt and total system cost
Installers in New Jersey typically quote $2.80 – $3.20 per watt for a straightforward roof-mounted system. Northern metro areas (the NY-orbit counties) run toward the top of the band; South Jersey and competitive suburban markets tend to the bottom. As everywhere, the final number rides on roof complexity, panel tier, whether a battery is included, and how many installers you actually get in a bidding war.
That range sits inside the national installed band of $2.50 – $3.50/W — see the full cost-per-watt breakdown and the whole-system cost guide rather than the thin national-vs-state table this page used to carry; the duplication didn’t help anyone.
New Jersey system price table (gross, before incentives)
| System Size | Typical Gross Cost (2026) | Typical Annual Output at 4.0–4.7 sun-hrs/day | Best For |
|---|---|---|---|
| 6 kW | $16,800 – $19,200 | 8,100 – 9,700 kWh | Small home / apartment |
| 8 kW | $22,400 – $25,600 | 10,800 – 12,900 kWh | Average 2,000–2,500 sq-ft home |
| 9 kW | $25,200 – $28,800 | 12,200 – 14,500 kWh | Average home + EV / heat pump |
| 10 kW | $28,000 – $32,000 | 13,500 – 16,100 kWh | Family home / full gas-to-electric swap |
| 12 kW | $33,600 – $38,400 | 16,200 – 19,300 kWh | Large home + pool + EV |
Ranges calculated from the $2.80 – $3.20/W state spread and rounded to the nearest $100. Annual output figures assume 4.0–4.7 peak sun hours per day.
New Jersey’s residential electricity rate: the number that drives the math
This page previously said “about $0.18/kWh” — that was the national average, not New Jersey’s. The state-benchmarked number is materially different. The U.S. Energy Information Administration’s most recent monthly state table (data for June 2026, released August 26, 2026) puts New Jersey’s average residential price at 24.95¢/kWh, against an 18.34¢ national residential average. Source: EIA, Electric Power Monthly, Table 5.6.A — Average Price of Electricity to Ultimate Customers by End-Use Sector, by State, June 2026 (retrieved 2026-09-05). Note this is a state average — your actual rate depends on your utility (JCP&L, PSE&G, Atlantic City Electric, Rockland Electric, or a municipal/co-op) and your rate class plan.
Two honest caveats on using the average in payback math:
- It’s an average of many rate plans. Some homes are on fixed standard-offer rates, some on TOU; the EIA figure is what the sector paid, which is the right base for a state-level estimate and an imprecise tool for your specific bill.
- Rate escalation helps you or hurts you depending on direction. Power prices can and do move down as well as up — so treat no-escalation as the conservative baseline and escalators as upside, not the other way around.
The payback example, worked at the actual New Jersey rate
Let’s run a real 2026 example with the verified rate. No federal credit, no wishful export prices.
Setup: a 9 kW system at the midpoint of the New Jersey range, $3.00/W → $27,000 gross. New Jersey averages roughly 4.0–4.7 peak sun hours per day; take 4.3 and a realistic 0.80 system derate (inverter, wiring, shading, temperature, soiling):
- 9 kW × 4.3 h/day × 0.80 × 365 ≈ 11,300 kWh/year of usable output, ≈ 940 kWh/month.
Bill savings at the 2026 rate:
- 11,300 kWh/year × $0.2495/kWh (net metering at full retail) ≈ $2,820/year of offset retail electricity.
- Note: net metering means you’re offsetting purchases at retail — this is a savings figure, not a check. And it slightly overstates the first-year picture if some months’ generation is exported and credited at retail; under New Jersey’s full-retail regime with annual true-up, retail-rate offset is the standard model.
Add SREC-II (SuSI) income: qualifying New Jersey systems earn certificates per MWh for 15 years at a state-set price. At a commonly cited certificate value of roughly $50–$90 per MWh ($0.05–0.09/kWh):
- 11.3 MWh/year × $50–$90 ≈ $565 – $1,015/year more, before any tax treatment on the income.
Simple payback:
- With SREC-II: $27,000 ÷ ($2,820 + ~$790 midpoint) ≈ $27,000 ÷ $3,610 ≈ 7.5 years, before considering that certificate income is taxable and that rate plans vary — say 8–10 years realistically.
- Without SREC-II: $27,000 ÷ $2,820 ≈ 9.6 years; with a conservative lower rate or sub-4-hour sun nearer 11–13 years.
That lands a shade inside — not under — the 10–13-year frame society pages were using pre-2026, and the reason is exactly the rate: every cent per kWh is worth about $113/year on this system (11,300 kWh × $0.01). Twenty-five-year cumulative savings on this example, at $0.2495/kWh with no escalation, reach roughly $70,000 in bill offsets, plus $8,500 – $15,300 of certificate income over 15 years (11.3 MWh/yr × $50 – $90/MWh × 15). Those are arithmetic outputs, not predictions — escalation, degradation (~0.5%/yr is typical for modern panels), and O&M all shift the totals.
| Scenario | Annual offset value | Simple payback |
|---|---|---|
| Bill savings only, $0.2495/kWh | ~$2,820/yr | ~9.6 yrs |
| + SREC-II at $50/MWh | ~$3,385/yr | ~8 yrs |
| + SREC-II at $90/MWh | ~$3,835/yr | ~7 yrs |
| Solar + battery (10 kWh, ~$1,000–1,400/kWh installed) | adds 3–6 yrs to payback | verify with your utility’s TOU/export rates |
Three things to verify with your utility and installer before signing: your actual kWh price and rate plan, the current SREC-II certificate price and your eligibility window (program details evolve and tranches fill), and whether your utility applies any fixed charges that net-metering households see.
What’s different in New Jersey
Skip the national lists — New Jersey’s actual incentive and program landscape in 2026, per the page’s existing research and current state sources:
- SREC-II / SuSI (Successor Solar Incentive Program): qualifying residential systems earn Solar Renewable Energy Certificates sold through the state-administered program at a set price per MWh, typically for 15 years — a genuine second income stream on top of bill savings. This is the biggest single differentiator versus most states. Confirm current eligibility, enrollment windows, and certificate pricing with your installer at quote time.
- Full-retail net metering with annual true-up: our net-metering tracker (August 2026) lists New Jersey among the roughly two dozen full-retail states — one of the strongest export-compensation deals in the country. Verify the tariff text with your utility, since caps and fees vary by utility.
- Garden State Energy Storage Program: the NJBPU is actively rolling out battery incentives — the BPU’s own homepage (retrieved 2026-09-05) details the advanced Garden State Energy Storage Program proposal, with residential battery incentives structured around whole-home backup for low- to moderate-income customers. If you’re considering storage, this is the program to track; check the NJBPU home page for current tranches.
- Sales tax exemption: solar equipment is exempt from New Jersey’s 6.625% state sales tax.
- Property tax carve-out: renewable energy systems are not assessed toward property tax increases — the added value doesn’t hike your assessed bill.
The honest read: with the federal check gone, SREC-II income plus retail-rate exports is what separates New Jersey from merely-average states — and both need verification at quote time because program tranches and utility tariffs evolve.
Is solar worth it in New Jersey in 2026?
Yes, for most sound-roof homeowners — with verified numbers. The math above says a typical 9 kW system at the verified June 2026 rate pays back in roughly 8–10 years with SREC-II income, 10–13 years without it, before rate escalation. That’s strong for a no-federal-credit world, and the drivers — 24.95¢/kWh residential electricity, full-retail net metering, and per-MWh certificate income — are all checked against current sources rather than 2025 assumptions. If your roof is shaded, old, or needs structural work, or if you’re planning a battery, run the specifics with your installer and utility before committing.
