How to Get the 30% Solar & Battery Discount After 25D Expired: Section 48E Leases, PPAs & the $7B EPA Solar for All Ruling (2026–2027 Guide)

1. Why Direct Homeowner Solar Credits (§25D) Ended—While Commercial Credits (§48E) Survived

Across the United States in late 2026, millions of households facing surging utility rates—driven by AI data-center load growth, PJM’s record $269.92/MW-day capacity auction clearing price, and winter heating demand—are discovering a critical divide in the federal tax code:

• Direct Cash or Loan Purchase (§ 25D — Expired): Under the statutory sunset enacted in 2025, the 30% Residential Clean Energy Credit expired for systems placed in service after December 31, 2025. The IRS and utility standard requires official Permission to Operate (PTO) by that deadline; a homeowner buying a $28,000 solar-plus-battery system with cash or a bank loan in 2026 receives $0 in direct federal Section 25D tax credits.
• Third-Party Ownership via Solar Lease or PPA (§ 48E — Active): Because a solar leasing company or Power Purchase Agreement (PPA) provider is a commercial entity that retains legal ownership of the energy property, the installation qualifies as commercial clean electricity property under Internal Revenue Code Section 48E.

Use this 100% client-side calculator to compare three real-world 2026–2027 choices for your home or facility: (1) buying a solar + battery system outright without Section 25D, (2) signing a $0-down Section 48E Lease/PPA where the provider passes through a portion of the 30%–40% commercial ITC, or (3) subscribing to a 20% discount Community Solar / Solar for All allocation.

3. Inside the September 2026 Federal Court Rulings Saving the $7 Billion “Solar for All” Program

Created under the Greenhouse Gas Reduction Fund (GGRF), the EPA’s $7 billion Solar for All program awarded 60 grants to states, territories, tribes, and regional coalitions to deliver residential rooftop solar, battery storage, and community solar to more than 900,000 low-income and disadvantaged households.

After the EPA attempted to terminate those signed grant agreements following the enactment of the One Big Beautiful Bill Act, coalition grantees challenged the clawback in federal court. In September 2026, both the U.S. District Court for the District of Rhode Island and the U.S. District Court for the District of Columbia ruled that the EPA’s termination of the $7 billion program was unlawful, holding that the agency could not retroactively cancel funds that had already been legally obligated through executed grant agreements.

• What It Means for Renters & Homeowners: As state energy offices and coalition grantees resume deployment (while advocacy groups such as the Environmental Protection Network urge the EPA to drop remaining appeals), eligible households can subscribe to community solar allocations or apply for state-administered low-income rooftop solar grants that guarantee at least a 20% to 25% reduction on monthly utility bills.
• How It Pairs with State HEEHRA Rebates: Households upgrading heating equipment ahead of the November 2026 Polar Vortex Disruption can combine community solar or a Section 48E solar lease with state-administered HOMES and HEEHRA point-of-sale heat pump rebates (up to $8,000).

4. 5 Contract Checks Before Signing a 2026 Section 48E Solar + Battery Lease or PPA

1. Demand a 0% Escalator (or Compare Against Utility Inflation): Many third-party PPA proposals default to a 2.9% annual price escalator. Ask the installer to quote both a 0% fixed-rate PPA and an escalated PPA so you can compare the 15-year Net Present Value (NPV).
2. Verify How Much of the 30%–40% Section 48E ITC Is Passed Through: Ask whether the financier is claiming the +10% Domestic Content adder (using US-manufactured solar modules, racking, or LFP batteries) and confirm that the monthly payment reflects the lower net capital cost.
3. Check the Year-6 Fair Market Value (FMV) Buyout Option: Because IRS Section 48E recapture rules sunset after 5 years of commercial operation, reputable third-party leases include an early buyout window beginning in Year 6.
4. Require Whole-Home or Critical-Load LFP Battery Backup: In time-of-use (TOU) utility territories such as California (NEM 3.0 / NBT) and the Northeast, a solar-only lease exports daytime power for pennies; pairing a 10–13.5 kWh LFP battery under the same Section 48E lease shifts stored solar into the 4–9 PM peak window. Model your storage payback in our Battery Storage ROI Calculator.
5. Confirm Production Guarantees & Inverter/Battery Replacement Coverage: One major advantage of a Section 48E lease/PPA over a cash purchase is that the third-party owner is contractually responsible for inverter and battery warranty replacements throughout the 20-to-25-year term.
