Solar After July 6, 2026: The Post-48E Market Reality
Updated July 9, 2026 · 8 min read
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 6, 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 actually changes, and what still works.
⚠ The bottom line
A $25,000 system that cost $17,500 after the old 30% credit now costs the full $25,000 for a cash or loan buyer. Payback periods stretch roughly 3–5 years. Leases and PPAs can still capture a 30% credit indirectly, because the installer claims it under Section 48E.
1. What Changed on July 6, 2026
The One Big Beautiful Bill Act (OBBBA, signed July 4, 2025) ended the Section 25D Residential Clean Energy Credit for property placed in service after December 31, 2025. It left the Section 48E Clean Electricity Investment Credit intact, but only for third-party-owned and commercial projects — and only for those that began construction before July 6, 2026.
Why July 6 and not July 4? The statutory construction-start deadline was July 4, 2026 — a Saturday. Under IRC 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 simply 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 the Solar ROI Calculator, which now defaults to 0% federal ITC for residential purchases.
3. Impact on Battery Economics
Batteries are hit even harder than panels. A $12,000 battery that effectively cost $8,400 after the credit now costs the full $12,000 for an owner. Time-of-use arbitrage and backup-power value rarely clear that gap on economics alone — battery ROI drops 30% or more without the credit. Where batteries still pencil out is leased storage (the installer claims 48E) or states with generous storage rebates. See the Battery Payback Calculator for the post-credit math.
4. Lease vs Buy After the Deadline
This is where the market actually moved. Because Section 48E remains available to the system owner, a lessor or PPA provider can still claim 30% and pass part of the value to you through lower monthly payments. The result is a financing inversion: for the first time, leasing can be cheaper than buying on a monthly basis, because the lease price bakes in a credit the buyer can no longer claim.
The catch is passthrough. Installers have no obligation to pass the full credit through, and many keep a large share as margin. Compare both paths side by side in the Financing Comparison tool, and read our 48E Passthrough Guide for the one question that reveals how much credit value you're actually getting.

5. Installer Fraud Warning
Some installers still quote 30% ITC on new owned residential systems. If construction began after July 6, 2026, that credit does not exist for you — subtracting it from the price is using an expired incentive, and may amount to fraud 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 6, 2026.
- Pressure to "lock in" a credit that, for a new purchase, no longer applies.
Verify any installer claim with the ITC Status Check or the Eligibility 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 simply 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 for leases, PPAs, commercial, and rental property
The homeowners who win in the post-48E era are the ones who price both paths — own vs lease — honestly before signing, and who stop assuming a 30% federal discount that, for a new purchase, no longer exists.
