FEOC Rules & Solar Tax Credits 2026: Section 25D Repeal Guide

Last updated: February 1, 2026

FEOC rules explained for solar buyers — what the Section 25D residential ITC repeal in early 2026 means, and which products still qualify for commercial Section 48/48E credit.

You've decided to go solar — now comes the hard part: choosing the right equipment from hundreds of options. The good news? Most modern solar products are reliable, and the differences that matter can be narrowed down to a few key specs. This guide helps you make decisions based on data, not marketing claims.

The Inflation Reduction Act (IRA) previously provided a 30% federal Investment Tax Credit (Section 25D ITC) for residential solar installations through 2032, but the residential portion was REPEALED in early 2026. Commercial Section 48/48E continues at 30% through 2032 (with a 10% domestic content bonus for US-manufactured components). Foreign Entity of Concern (FEOC) restrictions under IRA Sections 30D and 45X continue to limit tax credit eligibility for battery components sourced from China, Russia, North Korea, and Iran. With 110 solar panels, 72 inverters, and 74 batteries in our database, this guide covers what changed and what still qualifies.

Key Takeaways

• The federal residential ITC (Section 25D) was repealed in early 2026 — no longer applies to residential installations regardless of manufacturer origin
• FEOC restrictions primarily affect battery storage tax credits, not solar panels
• From 2025+, batteries with FEOC-sourced critical minerals lose ITC eligibility for the battery portion
• LFP cells manufactured in China may disqualify batteries from certain ITC bonus credits
• The 10% domestic content bonus requires US-manufactured panels, inverters, or racking
• Tesla Powerwall 3 (US-assembled), Enphase IQ Battery (US-assembled), and Generac PWRcell qualify as domestic
• Always verify current FEOC compliance with your installer — rules are evolving rapidly

Frequently Asked Questions

What is a Foreign Entity of Concern (FEOC)?

Under the IRA, a Foreign Entity of Concern is a company owned by, controlled by, or subject to the jurisdiction of China, Russia, North Korea, or Iran. This includes subsidiaries and entities where these governments hold 25%+ ownership or board control. The FEOC designation affects eligibility for certain clean energy tax credits, particularly for battery components and critical minerals used in energy storage systems.

Do FEOC rules affect the federal solar panel tax credit?

The federal residential ITC (Section 25D) was repealed in early 2026, so the 30% residential credit no longer exists regardless of FEOC status. Commercial solar projects continue to receive the 30% ITC under Section 48/48E, where FEOC restrictions primarily target battery storage credits and the separate 10% domestic content bonus adder. Chinese-made panels (LONGi, JinkoSolar, Trina, JA Solar) remain eligible for commercial ITC but no longer have residential federal credit.

Which batteries qualify for the ITC under FEOC rules?

Batteries assembled in the US with non-FEOC critical minerals have the clearest path to full ITC eligibility. Tesla Powerwall (assembled in California/Nevada), Enphase IQ Battery (assembled in the US), and Generac PWRcell are generally considered compliant. Batteries with Chinese LFP cells (including many budget options) may face restrictions on bonus credit eligibility. The base 30% ITC for residential battery storage currently applies regardless, but consult your tax advisor for the latest guidance.

What is the domestic content bonus and how do I get it?

The IRA offers a 10% bonus ITC for commercial solar projects (not residential Section 25D) that meet domestic content requirements: steel/iron must be US-produced, and 40%+ of manufactured component costs must be US-sourced (increasing to 55% by 2027). For residential homeowners, this bonus does not apply directly, but choosing US-manufactured equipment supports the domestic solar supply chain and may improve long-term warranty support.

Are Chinese solar panels going to lose their tax credit eligibility?

As of 2026, there is no legislation removing the 30% residential ITC for Chinese-manufactured solar panels. The FEOC rules under the IRA target battery components and critical minerals, not solar panels. However, separate trade policies (tariffs, anti-dumping duties) affect panel pricing. Chinese panels face 14.25–254% anti-dumping tariffs depending on the manufacturer, though many are manufactured in Southeast Asia to avoid these duties.

How do tariffs differ from FEOC restrictions?

Tariffs are import duties that raise the purchase price of foreign goods. FEOC restrictions determine tax credit eligibility. A Chinese-made panel may face tariffs (making it more expensive) but still qualifies for the 30% ITC. A battery with FEOC-sourced minerals may be cheap to buy but could lose bonus tax credit eligibility. These are two separate policy mechanisms that both affect the total cost of solar ownership.

What should I do to maximize my solar tax credits in 2026?

For maximum tax savings: (1) All solar panel brands qualify for the 30% ITC — choose based on performance and price. (2) For battery storage, prefer US-assembled batteries (Tesla Powerwall 3, Enphase IQ, Generac) to ensure full credit eligibility. (3) File IRS Form 5695 with your tax return. (4) The credit is nonrefundable — you need sufficient tax liability to claim it. (5) Consult a tax professional, as FEOC guidance continues to evolve through IRS rulemaking.
