Solar Loan vs Lease in NJ:
The Math Completely Flipped in 2026
The 30% federal tax credit for homeowners is gone. Here’s exactly how that changes the loan vs lease decision for New Jersey homeowners — with real numbers.
⚠️ Critical 2026 Update: The Federal Tax Credit Is Gone for Direct Purchases
The One Big Beautiful Bill Act, signed July 4, 2025, eliminated the residential Section 25D solar tax credit effective January 1, 2026. Homeowners who buy solar with cash or a loan receive zero federal tax benefit. This fundamentally changes the loan vs lease comparison. Every piece of solar advice written before 2026 that says “buy to get the 30% credit” is now outdated. See the full 2026 NJ incentives guide.
For a decade the conventional wisdom was clear: buy your solar system so you can claim the 30% federal tax credit. Leasing was for people who couldn’t qualify for financing. That rule is now obsolete. Here’s the new math — and what NJ homeowners actually need to consider in 2026.
📋 What’s in this guide
What Changed in 2026 — And Why It Matters
For years, the standard solar sales advice was: “Never lease. Always buy so you can claim the 30% federal Investment Tax Credit.” That advice was correct — until midnight on December 31, 2025.
The One Big Beautiful Bill Act eliminated the residential solar tax credit (Section 25D) for any system installed on or after January 1, 2026. There is no phase-down, no grandfathering, no exceptions for systems already contracted. If you install solar with a cash purchase or a loan in 2026, your federal tax benefit is exactly $0.
However — and this is the part most people miss — the commercial solar tax credit (Section 48E) was not eliminated. It remains available through 2027 for businesses and third-party solar owners. This is where leases and PPAs come in.
💡 The Section 48E Pathway — How Leases Still Access Federal Benefits
When you sign a solar lease or PPA, the solar company (not you) owns the panels on your roof. Because they’re a business, they can claim the Section 48E commercial investment tax credit — worth 30% of the system cost. To win your business, they factor that credit into your lease rate, effectively passing the savings to you as a lower monthly payment. In 2026, a lease or PPA is the only way a residential homeowner can access any federal solar tax benefit.
How a Solar Lease Works in NJ
In a solar lease or PPA (Power Purchase Agreement), a solar company installs panels on your roof and owns them for the life of the agreement — typically 20-25 years. You pay a fixed monthly rate for the electricity they produce, which is set below your current utility rate from day one.
The key mechanics for NJ homeowners:
- $0 upfront. No down payment, no installation fee. The solar company funds everything.
- Fixed monthly rate — lower than your current PSE&G, ACE, or JCP&L bill from day one.
- Company claims Section 48E — and passes the benefit through as a lower rate.
- Net metering credits apply. Surplus electricity sent to the grid credits your account at retail rate.
- Maintenance covered. The system owner handles repairs and performance guarantees.
- You don’t own the system — which has implications for home sales and long-term incentives.
📌 NJ-specific note: On a lease, the solar company typically retains the NJ SuSI TREC payments — not you. This is worth $12,000+ over 15 years on a typical 8kW system. It should be factored into your rate comparison. Always ask: “Who keeps the TREC payments?” before signing. More on this below.
How a Solar Loan Works in NJ
A solar loan lets you own your system outright while spreading the cost over time — typically 10-25 years. You apply for financing through your installer or a third-party lender, and the loan payment replaces your utility bill.
In 2026, the loan math looks meaningfully different than it did before the ITC expired:
- $0 upfront — the loan covers 100% of installation cost.
- No federal tax credit — the 30% ITC that made loans compelling is gone for 2026 purchases.
- You own the system — and keep all NJ SuSI TREC payments ($12,000+ over 15 years).
- Monthly payment may exceed your old utility bill — without the ITC to reduce principal, loan payments are higher.
- Full system ownership — no lease transfer complications when selling your home.
- 25-year warranty — after which the system is yours free and clear.
The 2026 Math Breakdown: Real NJ Numbers
Let’s run the actual numbers for a typical NJ homeowner — 8kW system, $200/month current utility bill, PSE&G territory at $0.26/kWh.

$0-Down Solar Lease
Solar Loan (Cash Purchase)
The takeaway from these numbers: In 2026, a lease delivers immediate monthly savings with no upfront risk. A loan gives you system ownership and TREC income but the monthly payment often exceeds your current utility bill — at least until the loan is paid off. The right choice depends entirely on your priorities and time horizon.
Full Comparison: Solar Lease vs Loan in NJ 2026
| Factor | $0-Down Lease / PPA | Solar Loan / Purchase |
|---|---|---|
| Upfront Cost | $0 | $0 (loan-financed) |
| Federal Tax Credit | 48E via installer — reflected in lower rate | None — ITC expired Jan 1, 2026 |
| Monthly Payment vs Old Bill | Lower from day 1 (20–35%) | Often higher initially without ITC |
| NJ SuSI TREC Payments | Installer keeps them (~$12K+ over 15 yrs) | You keep them (~$815/yr for 15 yrs) |
| Net Metering Credits | You keep them | You keep them |
| Maintenance & Repairs | Installer responsible for 25 years | Your responsibility after warranty |
| Own the System | No — installer owns panels | Yes — yours after loan paid off |
| Home Sale Complexity | Lease must transfer to buyer | Clean ownership transfer |
| 25-Year Savings Potential | Lower — TREC value given up | Higher — own system + TREC income |
| Best For | Immediate savings, no risk, low commitment | Maximum long-term value, system ownership |
The TREC Question Nobody Asks — But Should
This is the single most important thing to understand before signing any NJ solar agreement in 2026 — and the thing most solar companies hope you don’t ask about.
New Jersey’s SuSI program pays $85.90 per megawatt-hour of solar energy produced for 15 years. For a typical 8kW system producing ~9,500 kWh per year, that’s approximately $815 per year — $12,225 over the full term.
On a solar loan or cash purchase, those TREC payments go to you. On most leases and PPAs, they go to the installer — who uses them to offset the system cost and offer you a lower rate. This isn’t a scam, but it’s a significant financial consideration that changes the true comparison.
⚠️ Always Ask This Before Signing
Before you sign any NJ solar agreement — lease or loan — ask directly: “Who keeps the SuSI TREC payments under this contract?” If they’re vague, change the subject, or say you’ll get them when the contract clearly says otherwise — walk away. This one question can save you $12,000+.
When a Solar Lease Makes More Sense in 2026
✓ Choose a Lease When:
- You want immediate monthly savings from day one
- You don’t want maintenance responsibility
- Your tax liability is low — ITC wouldn’t help you anyway
- You plan to stay in the home long-term
- Cash flow matters more than long-term total value
- You want the 48E credit benefit without the paperwork
→ Consider a Loan When:
- You want to own your system and keep TREC payments
- You’re planning to sell your home — cleaner transfer
- Your monthly budget can handle a slightly higher payment initially
- You want maximum 25-year total savings
- You’re an investor thinking about the asset value
The Long-Term Case for Ownership — Still Real
Despite the ITC expiration, the case for ownership isn’t dead — it’s just longer-term. The math works like this:
A homeowner who purchases an 8kW system in 2026 will pay higher monthly payments than a lease customer for the first 10-12 years of the loan term. But after the loan is paid off, they have a fully owned system producing free electricity — plus 15 years of TREC income totaling $12,000+. Over a 25-year horizon, ownership typically delivers $15,000-25,000 more in total value than a lease, depending on your utility rate and system performance.
The question is whether the short-term cash flow difference is worth the long-term gain to you specifically. For some homeowners it absolutely is. For others — particularly those with tighter monthly budgets — the immediate savings of a lease are the right call.

This is the second biggest concern after monthly costs — and both structures have nuances worth understanding.
If you have a lease: The lease must either transfer to the buyer or be bought out before closing. Most buyers are comfortable assuming a lease if the payment is lower than the local utility rate — which it typically is. See our full guide to selling a home with solar in NJ.
If you have a loan: You can either pay off the loan before sale (using sale proceeds) or transfer it to the buyer as an assumption. Owned solar systems are generally easier to deal with in a sale — the value is captured in the appraisal and there’s no ongoing lease agreement to negotiate.
In both cases, NJ’s property tax exemption applies — solar panels increase your home’s appraised value without increasing your tax assessment.
