Solar After July 4, 2026: The Post-48E Market Reality

The single biggest assumption behind every solar calculator on this site — the 30% federal tax credit — is now gone for new residential purchases. On July 4, 2026, the Section 48E construction-start deadline closed. If you buy and own a system for your primary residence today, there is no federal credit to claim. Here's what that changes, and what still works.

1. What Changed on July 4, 2026

The One Big Beautiful Bill Act (OBBBA, signed July 4, 2025) ended theSection 25D Residential Clean Energy Credit for property placed in service after December 31, 2025. It left theSection 48E Clean Electricity Investment Creditintact, but only for third-party-owned and commercial projects — and only for those that began construction before July 4, 2026.

Why July 6 and not July 4? The statutory construction-start deadline was July 4, 2026 — a Saturday. UnderIRC 7503, when a federal deadline falls on a weekend or legal holiday, it rolls to the next business day. That made the effective cutoff Monday, July 6, 2026. As of today, that deadline has passed, so new projects can no longer start construction in time to qualify.

2. Impact on Solar ROI

Without the 30% credit, payback math shifts dramatically for purchased systems. A typical 8 kW system at $25,000 used to net out at $17,500 after the credit; today a cash or loan buyer pays the full amount. That pushes payback from roughly 6–8 years out to 9–13 years in most states, and longer where sunlight or local rates are less favorable.

The economics are not impossible; they are honest now. High-electricity-rate states (California, the Northeast) can still clear payback inside a panel's 25-year warranty. Low-rate states often cannot, without strong state or local incentives. Run your own numbers in theSolar ROI Calculator, which now defaults to 0% federal ITC for residential purchases.

3. Impact on Battery Economics

Batteries are the exception most pages get wrong. The July 4, 2026 construction-start cutoff terminates wind and solar only —26 USC 48E(e)(4)(C) exempts energy storage. Standalone and paired storage claimed by an eligible owner (commercial, rental, or third-party-owned) follows the standard 48E phase-down instead: 30% for construction starts through 2033, 75% in 2034, 50% in 2035, zero after. Storage is also outside the 48E(i) lease denial, which cites only solar and wind property. What did NOT change: an owned battery on a primary residence gets $0 federal credit (25D expired; 48E is a business credit). Where batteries pencil out is states with generous storage rebates, leased/TPO storage whose lessor still captures the 48E storage credit, or TOU arbitrage at high rate spreads. See theBattery Payback Calculatorfor the post-25D math.

4. Lease vs Buy After the Deadline

This is where the market got complicated. One widely repeated claim — that a lessor "claims the same 30% you lost" and bakes it into your lease price — is not what the statute says.Section 48E(i) denies the 48E credit for solar property leased to a dwelling unit, so a lessor of residential systems generally has no 30% credit to pass through on new contracts.

Third-party ownership can still cost less per month, but for commercial reasons rather than a tax-credit passthrough: lessors depreciate the equipment, buy at commercial scale with cheaper capital, and spread your cost over many systems. Whether aPPA structured as a power sale rather than an equipment lease avoids 48E(i) is an open question that matters here — until it is settled or reviewed by tax counsel, treat any "we still get the 30%" pitch from a residential lease salesperson with skepticism and ask which code section and ownership structure supports it.

5. Installer Fraud Warning

Some installers still quote 30% ITC on new owned residential systems. If construction began after July 4, 2026, that credit does not exist for you — subtracting it from the price is using an expired incentive, and may amount tofraud or a misrepresentation of the deal. Red flags:

• A cash/loan quote that subtracts a "30% federal tax credit."
• The salesperson cannot say whether it is Section 25D or 48E.
• No documentation of a construction-start date before July 4, 2026.
• Pressure to "lock in" a credit that, for a new purchase, no longer applies.

Verify any installer claim with theITC Status Check or theEligibility Checker.

6. State-Level Considerations

With the federal floor removed, state and local incentives now carry most of the weight. The value of going solar in 2026 varies more by ZIP code than ever before:

• States with strong net metering, SREC markets, or rebates can still make ownership attractive.
• States with low retail rates and no incentives may favor leasing.
• Property-tax exemptions on the added home value still apply in many states, softening the ownership cost.

7. What You Can Still Do

The federal residential credit is gone, but solar is not dead — the incentive structure shifted. Here is what still works:

• State income tax credits and cash rebates
• Net metering or net billing where your utility still offers it
• Solar Renewable Energy Credits (SRECs) in active markets
• Property tax exemptions on the added home value
• Utility and state battery-storage rebates
• Section 48E storage credit — exempt from the July 4, 2026 cutoff (48E(e)(4)(C)); phases down after 2033 instead
• Section 48E for commercial projects that began construction before July 4, 2026

The homeowners who win in the post-48E era are the ones who price both paths, own vs lease, before signing, and who stop assuming a 30% federal discount that, for a new purchase, no longer exists.
