The federal residential tax credit expired. Solar skeptics say it's over. They're wrong. NJ solar economics in 2026 are stronger than Texas or Florida ever were — even when those states had the full 30% ITC. Here's the math.
Quick Answer
NJ solar ROI in 2026 is better than most states that still had the federal ITC because NJ electricity rates are 60% above the national average, ADI income provides $5,000-$12,000 over 15 years, property tax exemption saves $500-$1,200 per year, and sales tax exemption saves $1,600-$2,300 upfront. Typical NJ solar payback is 5-7 years.
The Section 25D residential solar tax credit expired December 31, 2025. Many homeowners assume solar is no longer worth it. The reality is the opposite: NJ solar ROI in 2026 is better than solar ROI in Texas, Florida, or Arizona when those states had the full 30% ITC. Why? Because NJ's electricity costs 60% more than the national average, NJ's ADI program pays you $5,000-$12,000 over 15 years for producing solar energy, NJ exempts solar from property tax (saving $500-$1,200/year in the nation's highest-tax state), and NJ exempts solar from sales tax (saving $1,600-$2,300 upfront). The ITC was nice, but NJ's state-level benefits are collectively worth more.
NJ solar does not rely on any single incentive. It's the stacking of six independent value streams that makes NJ one of the best solar markets in the country — federal tax credit or not.
NJ rates are 60% above national average. Every kWh your panels produce is worth $0.18-$0.26 in NJ vs $0.12-$0.16 nationally. This is the single biggest driver of NJ solar ROI.
NJ pays $40-$80/MWh for 15 years through the ADI (Administratively Determined Incentive) program. This production-based income does not exist in most states. Total 15-year ADI income: $5,000-$12,000.
NJ has the highest property taxes in the US (average $9,500/yr). Solar adds $15,000-$25,000 in home value but this increase is 100% exempt from property tax in NJ. In states without this exemption, solar increases your tax bill.
NJ exempts solar equipment from the 6.625% state sales tax. On a $25,000-$35,000 system, that is $1,600-$2,300 in immediate savings. This reduces your effective system cost on day one.
NJ provides full retail net metering — every kWh you export to the grid offsets a kWh at your full retail rate ($0.18-$0.26/kWh). Many states have reduced net metering to wholesale rates ($0.03-$0.05/kWh), dramatically reducing solar value.
NJ electricity rates have risen faster than the national average. Solar locks in your effective rate at $0/kWh for energy produced. By year 10, when NJ rates could reach $0.30-$0.40/kWh, your annual savings multiply substantially.
This comparison shows NJ in 2026 without any federal ITC versus Texas and Florida when they had the full 30% residential ITC. NJ still wins on total ROI.

* TX and FL system costs shown after 30% ITC reduction (when the credit was active pre-2026). NJ system cost is the full cost with no federal ITC. Despite paying the full price, NJ delivers better 25-year returns and faster payback.
NJ wins on 8 out of 11 metrics — including the only ones that truly matter: 25-year total savings and payback period. The ITC is a one-time event; electricity rates, ADI income, and tax exemptions compound year after year. NJ's recurring benefits outweigh a one-time 30% discount within 5-7 years.
Beyond the obvious savings, NJ solar has three compounding advantages that most ROI calculators undercount or ignore entirely.
NJ's average property tax is $9,500/year — the highest in the nation. Solar adds $15,000-$25,000 in appraised home value. Without the exemption, that would increase your taxes by $500-$1,200/year. Instead, you get the home value increase with zero tax penalty.
Most ROI calculators use today's electricity rate for all 25 years. That dramatically underestimates your savings. NJ rates have risen 4-6% annually for a decade. At 5% annual escalation, your year-15 savings are roughly double your year-1 savings — and year-25 savings are triple.
NJ is one of the few states where you get paid twice for the same kWh. When your panels produce 1 kWh, you save $0.22 on your electric bill through net metering AND earn $0.04-$0.08 in ADI income. That same kWh is worth $0.26-$0.30 total — more than double what most states pay per kWh of solar production.
Cumulative savings for a typical 8-10 kW NJ solar system purchased in 2026. Includes electricity savings, ADI income, property tax exemption, and sales tax exemption. Assumes 5% annual rate escalation and $0.22/kWh starting rate.
| Milestone | Cumulative Savings | Notes |
|---|---|---|
| Year 1 | $4,500-$5,800 | Electricity savings + ADI income + sales tax exemption + property tax exemption |
| Year 5 | $24,000-$30,000 | Rate escalation increasing annual value by 4-6%/year |
| Year 10 | $55,000-$68,000 | System fully paid off (if financed). Pure profit from here. |
| Year 15 | $90,000-$110,000 | ADI contract ends. Still saving on electricity + property taxes. |
| Year 20 | $120,000-$148,000 | NJ rates potentially $0.40-$0.55/kWh. Massive annual savings. |
| Year 25 | $155,000-$192,000 | Total lifetime value. Panels still producing at 87-93% capacity. |
Solar skeptics have been saying the same things for years. Here are the most common anti-solar talking points and why they do not hold up in NJ.
More kWh offset = more savings at NJ's high rates
Highest rates in NJ ($0.22-$0.26/kWh) = fastest payback
Long enough to capture full ADI contract and rate escalation
Bigger system = more production = more ADI income
Property tax exemption saves more at higher assessed values
Smaller system, less savings — but still positive ROI by year 8-10
Lower production reduces both savings and ADI income — consider tree trimming
May not recoup full cost, but home value increase offsets most of the investment
System size limitations reduce total savings — premium equipment helps
Lower rates ($0.17-$0.20/kWh) mean slightly slower payback than PSE&G/JCP&L
Every year you delay solar in NJ, you lose money. Here is what one year of waiting actually costs.
This is money you permanently lose — it cannot be recovered by installing later. And the cost compounds: year 2 of waiting costs even more because rates have increased further.
Yes. The 25D residential solar tax credit expired December 31, 2025, but NJ solar economics are driven primarily by high electricity rates ($0.18-$0.26/kWh), ADI production income ($5,000-$12,000 over 15 years), property tax exemption ($500-$1,200/year), and sales tax exemption ($1,600-$2,300 upfront). These NJ-specific benefits create a 6-8 year payback period and $72,000-$92,000 in 25-year savings — better than most states even when they had the 30% ITC.
A typical 8-10 kW NJ solar system saves $72,000-$92,000 over 25 years. This includes electricity bill savings (growing annually with rate escalation), ADI production income for the first 15 years, property tax exemption savings every year, and the upfront sales tax exemption. With NJ electricity rates rising 4-6% annually, the savings accelerate dramatically in later years.
NJ solar systems typically pay back in 6-8 years in 2026 — even without the federal ITC. This is faster than the national average of 8-12 years. NJ's high electricity rates, ADI income, and tax exemptions combine to create one of the fastest payback periods in the country. If you finance with a solar loan, your monthly loan payment is often lower than your previous electric bill from month one.
NJ solar beats Texas and Florida on ROI despite getting less sunshine. NJ's electricity costs 60-70% more per kWh, providing larger dollar savings per kWh produced. NJ's ADI program pays $5,000-$12,000 over 15 years (TX and FL have no equivalent). NJ's property and sales tax exemptions add $1,600-$2,300 upfront and $500-$1,200/year. Even with no ITC, NJ achieves a 6-8 year payback vs 9-12 years in TX.
ADI (Administratively Determined Incentive) is NJ's solar production incentive — the successor to the SREC/SREC-II programs. ADI pays solar owners $40-$80 per MWh (megawatt-hour) based on actual, metered production for 15 years. A typical 8 kW NJ system earning $80/MWh generates $770-$860/year in ADI income. Over 15 years, total ADI income is $5,000-$12,000 depending on system size and production.
Yes. National studies (Lawrence Berkeley National Lab) show solar panels increase home value by $3-$4 per watt. An 8 kW system adds approximately $24,000-$32,000 in home value. In NJ, this increase is 100% exempt from property tax under N.J.S.A. 54:4-3.113a. With NJ having the highest average property taxes in the US ($9,500/year), this exemption saves $500-$1,200 annually that you would otherwise owe on the increased assessment.
No. Solar panel hardware prices have stabilized after an 80% decline from 2010-2020. Meanwhile, NJ electricity rates rise 4-6% annually and ADI rates may decline over time as the market matures. Every year you wait, you lose $2,000-$3,000 in electricity savings and one year of ADI income. The cost of waiting exceeds any realistic future price reduction.
The three most-overlooked NJ solar ROI boosters are: (1) Property tax exemption — your home value increases $24,000-$32,000 but your property taxes do not rise, saving $500-$1,200/year in a state with the nation's highest property taxes. (2) Rate escalation amplification — at 5% annual rate increases, your savings in year 15 are roughly double your year-1 savings. (3) ADI income stacking — ADI income is separate from electricity savings, effectively paying you twice for the same kWh produced.
