$27,000 Solar System in 2026: New Jersey's ITC + SREC Stack Hits a 6-Year Payback — Why Texas Gets 12 Years on the Same Roof
$27,000 Solar System in 2026: New Jersey's ITC + SREC Stack Hits a 6-Year Payback — Why Texas Gets 12 Years on the Same Roof
Your utility just announced a rate increase. Your neighbor just got three solar quotes. And somewhere between those two facts, you're trying to figure out whether this actually makes financial sense for your house — not your neighbor's, not the case study in the installer's brochure, yours.
Here's the thing that most solar conversations skip: the 30% federal Investment Tax Credit saves you exactly $8,100 on a $27,000 system regardless of whether you're in Trenton, New Jersey, Austin, Texas, or Jaffrey, New Hampshire. The ITC is the great equalizer. Everything after it is not.
Two homeowners with identical roofs, identical systems, and identical federal credits can face a 6-year payback or a 12-year payback depending on their state's incentive stack, their utility's rate structure, and whether net metering still pays them retail rate for excess power. Let me show you exactly where the gap comes from.
The Baseline: What the 30% Federal ITC Actually Does
The ITC — Investment Tax Credit — lets you subtract 30% of your solar system's installed cost directly from your federal income tax bill. Not a deduction off income. A credit, dollar for dollar, off what you owe.
On a $27,000 system: 30% × $27,000 = $8,100 back at tax time, assuming you have at least that much federal tax liability. (If you don't, the credit rolls forward — but that's a separate conversation.)
After the ITC, your effective out-of-pocket is $18,900. That number is the same in every state. What happens next depends entirely on your ZIP code.
Based on Elovane's analysis of 171 incentive programs in our DSIRE database and 648 cost data points from the NREL Annual Technology Baseline, the difference between a well-incentivized state and a bare state adds another $3,000–$7,000 in net savings beyond the federal credit — before you even count rate structure advantages. Stack those together and the gap between states becomes enormous.

The Three-State Comparison: New Jersey, New Hampshire, Texas
Let's run the real math on the same 8 kW rooftop system in three states. Production estimates come from NREL's PVWatts model, reflected in Elovane's 6,287-row county solar dataset. Utility rates come from our EIA electricity prices database (3,672 rows of state-level residential data). Incentives are pulled from our DSIRE program tracking.
New Jersey: The Full Incentive Stack
New Jersey is one of the strongest states in the country for residential solar right now — not because of any one program, but because of how several layers stack on top of each other.
8 kW system, south-facing, moderate suburban shading:
- Gross system cost: $27,000
- Federal ITC (30%): −$8,100
- Net after ITC: $18,900
Annual production (NREL irradiance data, central NJ): ~9,800 kWh/year
Utility rate (EIA residential dataset, NJ 2025–2026 average): ~$0.18/kWh
Annual savings from bill offset: 9,800 × $0.18 = $1,764/year
Now here's where New Jersey separates. An SREC — Solar Renewable Energy Certificate — is a tradeable credit representing 1 MWh (1,000 kWh) of solar electricity your panels actually produce. New Jersey runs one of the most active SREC markets in the country. Under the state's Successor Solar Incentive (SuSI) program, TRECs (Transition RECs) have been trading in the $85–$110/MWh range in 2025–2026. Your 9,800 kWh system generates roughly 9–10 SRECs per year.
At $90/SREC: ~$900/year in additional income for the first 15 years.
Total Year 1 economic benefit: $1,764 + $900 = $2,664
Simple payback on $18,900: $18,900 ÷ $2,664 = 7.1 years
But utilities don't freeze rates. Our EIA dataset shows NJ rates have escalated at 3.5–4.5% annually over the past decade. Running the numbers at three escalation scenarios:
| Rate Escalation Assumption | Payback WITH SRECs | Payback WITHOUT SRECs |
|---|---|---|
| 2% per year | 8.5 years | 10.7 years |
| 4% per year | 6.8 years | 9.1 years |
| 6% per year | 5.6 years | 7.8 years |
At the baseline 4% escalation assumption with the full SREC stack: New Jersey breaks even in under 7 years. That's a genuinely strong return on $18,900.
This is the kind of state-by-state incentive analysis Elovane runs automatically — because no installer quote accounts for SREC income curves, rate escalation trajectories, or how your specific utility rate tier affects the calculation.
New Hampshire: High Rates, Thin Incentives, a Community Solar Alternative
New Hampshire has some of the highest residential electricity rates in the continental U.S. — our EIA dataset puts the NH residential average at $0.23–$0.25/kWh in 2025–2026. That's a structural tailwind for solar. But the state's incentive landscape is sparse compared to New Jersey.
Same 8 kW system, NH conditions:
- Gross cost: $27,000
- Federal ITC: −$8,100
- Net after ITC: $18,900
- State rebates: minimal (no NH solar tax credit; some small utility rebates exist but aren't transformative)
Annual production (NREL data, southern NH): ~8,800 kWh/year (fewer peak sun hours than NJ)
Annual savings: 8,800 × $0.23 = $2,024/year
No SREC market in New Hampshire.
Simple payback: $18,900 ÷ $2,024 = 9.3 years. With 4% rate escalation, that improves to roughly 8.5 years — still 1.5–2 years longer than New Jersey despite higher electricity prices, purely because of the absent SREC income.
There's an interesting alternative worth knowing about here. ReVision Energy just announced development of a 1.34 MW community solar array on a former municipal landfill in Jaffrey, New Hampshire, expected online in early 2027. For NH homeowners with shaded roofs, north-facing orientations, or no desire to own equipment, community solar subscriptions typically deliver 10–15% discounts on utility bills — no upfront capital, no ITC benefit to you directly, but roughly $230–$350/year in savings on a 10,000 kWh household. No installation, no permits, no roof penetrations.
The tradeoff: you're giving up the ownership economics (no SREC income, no ITC, no asset on your balance sheet) for simplicity and zero capital risk. Our full breakdown of community solar vs. rooftop solar payback math shows where the crossover point lands depending on your roof situation.
Texas: Maximum Sun, Minimum Incentives, Slow Payback
Texas presents the sharpest counterintuitive result. The state has excellent solar irradiance — among the best in the continental U.S. — but also some of the lowest average residential electricity rates, and almost no state-level solar incentives beyond property tax exemptions.
Same 8 kW system, central Texas:
- Gross cost: $27,000
- Federal ITC: −$8,100
- Net after ITC: $18,900
- State incentives: property tax exemption on added home value (real value, but doesn't touch upfront cost)
- No SREC market
Annual production (NREL county solar dataset, Austin-area): ~11,200 kWh/year
Average rate (EIA residential dataset, Texas 2025–2026): ~$0.13–$0.15/kWh
Annual savings: 11,200 × $0.14 = $1,568/year
Simple payback: $18,900 ÷ $1,568 = 12 years. With 4% escalation: ~10.5 years.
Texas produces 14% more electricity than New Jersey on the same system — and still carries a payback period that's 55% longer. That single number illustrates why your utility rate matters more than your roof.
| State | Annual Production | Avg. Rate | SREC Income | Net System Cost | Payback (4% escalation) |
|---|---|---|---|---|---|
| New Jersey | 9,800 kWh | $0.18/kWh | ~$900/yr | $18,900 | 6.8 years |
| New Hampshire | 8,800 kWh | $0.23/kWh | None | $18,900 | 8.5 years |
| Texas | 11,200 kWh | $0.14/kWh | None | $18,900 | 10.5 years |

The Infrastructure Shift — and Why It Doesn't Mean the Numbers Don't Matter
PV Magazine USA reported this week that residential solar demand is fundamentally changing character: homeowners are increasingly treating panels as essential infrastructure — like a roof or HVAC — rather than a financial product justified primarily by incentives. Energy independence, grid resilience, and rising electricity consumption from EVs and heat pumps are all driving the shift.
That's not wrong. But "infrastructure" framing can become a backdoor for skipping the math. Here's why the calculation still matters more than ever.
When a household adds an EV or heat pump, electricity consumption can jump 30–50%. A home using 12,000 kWh/year before electrification might use 16,000–18,000 kWh/year after. At $0.18/kWh, that's an extra $720–$1,080/year in utility exposure that a properly sized solar system could offset. Our NREL solar defaults dataset confirms that an 8 kW system sized for pre-electrification needs will routinely underperform for a fully electrified home — meaning the payback assumptions in your quote may be built on the wrong consumption baseline.
If you're planning an EV or heat pump alongside solar, the sequencing of those upgrades can move your 25-year economics by several thousand dollars in either direction.
The Domestic Content Wildcard: FH Capital + JinkoSolar and the Hidden 10% Adder
This week, private equity firm FH Capital announced a deal to acquire a 75.1% majority stake in JinkoSolar's U.S. manufacturing subsidiary, with the stated goal of expanding domestic module and battery production capacity. Alongside similar moves across the industry, this is worth watching closely — because domestic manufacturing has a direct line to your tax credit.
The IRA includes a 10% domestic content bonus on top of the base 30% ITC for systems using qualifying U.S.-manufactured components. On a $27,000 system:
- Base ITC (30%): $8,100
- Domestic content adder (10%): $2,700
- Total credit with domestic content: $10,800
- Net system cost after full stack: $16,200
At $16,200 net with New Jersey's SREC income ($900/year) and $1,764/year in bill offset: payback drops to $16,200 ÷ $2,664 = 6.1 years — essentially one full year faster than the base ITC scenario.
Not every installer today qualifies for the domestic content adder. But as JinkoSolar's U.S. manufacturing scales and tariff exposure on imports increases, qualifying equipment is becoming more available. When you get quotes, ask explicitly: "Does this system qualify for the IRA domestic content bonus?" A $2,700 difference is not a rounding error.
On the tariff side, our NREL ATB cost data shows that import tariff exposure has been adding roughly $800–$1,600 to 8 kW residential system costs depending on panel sourcing. Domestic production insulates against that risk — another reason the FH Capital deal has downstream implications for residential buyers.
The Sunrun Storage Pivot: A Signal About Where Incentive Math Is Heading
Sunrun, the largest residential solar-plus-storage installer in the country, just reported Q1 2026 results. They maintained full-year guidance while explicitly emphasizing a pivot toward storage and grid services as their core strategy — what management called a "margin of safety" approach amid industry volatility and ongoing net metering rollbacks.
Read between the lines: the industry's biggest player is betting that standalone solar, without storage, becomes economically suboptimal as export credits erode. For homeowners in states with stable retail-rate net metering — New Jersey is a current example — this isn't an immediate concern. But in states where net metering has already been cut or is under pressure, a battery that stores solar for evening self-consumption can recover 2–3 years of otherwise lost payback. Our analysis of how a $10,500 home battery interacts with TOU rate structures shows exactly when that math works in your favor — and when it doesn't.
The question you need to answer before signing any solar contract: Is my state's net metering policy stable enough to build my payback model around? Our state-by-state net metering guide is the right place to start.
The Five Variables That Actually Determine Your Payback
After walking through New Jersey, New Hampshire, and Texas, the real lesson isn't about geography — it's about variables. These five inputs determine whether solar pays off in 6 years or 12, and none of them show up accurately in a standard installer quote:
- Your actual utility rate — not the state average; your specific rate tier, TOU structure, and demand charge exposure
- Your roof's real production — orientation, shading analysis, and local irradiance by ZIP code
- Your full incentive stack — ITC + state tax credit + SREC eligibility + utility rebate, layered in the correct order
- Your net metering compensation rate — retail, avoided cost, or something in between, and whether it's at risk
- Your rate escalation assumption — our EIA dataset shows that at 2% vs. 6% annual escalation, the same $18,900 net system has a 3–4 year swing in payback over 25 years
Elovane's analysis pulls from 10,850 data points across NREL production models, EIA rate data, DSIRE incentive programs, FRED financing rates, and NREL cost benchmarks precisely because these variables interact differently in every ZIP code. The installer giving you a quote is optimizing for their close rate. You need to optimize for your household economics.
Run your ZIP code, roof orientation, current utility bill, and financing preference at Elovane before you sign anything — because the difference between a 6-year payback and a 12-year payback is entirely in the variables that only you can supply.
