The 2026 Battery Tax Credit: Why Storage Still Qualifies — And Solar Doesn't

Here's a sentence you'll read on a lot of solar websites this year: "Battery storage still qualifies for the 30% federal tax credit."

It's half true, and the half that's missing is the half that matters to you. If you're a homeowner who buys a battery with cash or a loan, you cannot claim it. You never could — the credit those articles are describing was never written for you.

But the underlying fact is real, and it's more interesting than the simplified version: Congress carved energy storage out of the credit termination that killed solar, and it did so explicitly in the statute. Understanding which credit applies to whom — and to which technology — is the difference between a contract that passes real value to you and one that doesn't.

Let's walk through it with the actual sources.

Two credits, two completely different audiences

Almost all confusion in this area comes from treating "the solar tax credit" as one thing. It was always two:

Sources: IRC §25D, §48E; IRS, "Clean Electricity Investment Credit."^[1][2]

If you buy a system, you were always in the 25D column. That column is now empty. If a company owns the system on your roof, it's in the 48E column — and that column still has value in it.

What actually happened to 25D

The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025 as Public Law 119-21, ended the residential credit almost a decade ahead of its original schedule.^[3]

The mechanics matter:

• The cutoff is placed in service after December 31, 2025 — not "ordered by," not "installed by." A system that was contracted in 2025 but energized in 2026 does not qualify.
• There is no phase-down. The credit went from 30% to 0% in a single step.
• It applies to homeowner-owned solar, batteries, and other qualifying property.

So for a 2026 cash or loan purchase: the federal credit is $0, for solar and for batteries alike.^[2][4] That is the part of this story that is unambiguous.

What Section 48E actually is

Section 48E replaced the older investment tax credit framework with a technology-neutral version. It's worth understanding its shape, because the numbers are bigger than most homeowners realize.

Per the IRS:

"The base amount of the Clean Electricity Investment Credit is 6 percent of the qualified investment. Credit is increased by up to: 5 times or up to 30% for facilities meeting prevailing wage and registered apprenticeship requirements; 10-percentage points for facilities meeting certain domestic content requirements...; 10-percentage points if located in an energy community."^[1]

In plain terms: the base is 6%, and meeting the prevailing-wage and apprenticeship standard multiplies it fivefold to 30%. Projects can stack adders for domestic content and energy-community location, reaching higher totals. The credit is also eligible for direct payment or transfer — meaning the owner can monetize it even without tax liability.^[1]

Critically, the IRS states the credit is available for "a qualified facility and energy storage technology placed in service after Dec. 31, 2024."^[1] Storage is named in the statute as its own category.

The split: Congress killed solar's clock and left storage's running

This is the part that most 2026 coverage glosses over, and it's the most useful thing in this article.

OBBBA added new subsections — §45Y(d)(4) and §48E(e)(4) — that terminate the production and investment credits for wind and solar. The IRS's guidance (Internal Revenue Bulletin 2025-36) describes the rule and, in the same sentence, carves out an exception:

"For purposes of this notice, the term 'applicable wind facility' means an applicable facility as provided in §§ 45Y(d)(4)(B)(i) and 48E(e)(4)(B)(i) (except as provided in § 48E(e)(4)(C) relating to energy storage technology) and 'applicable solar facility' means an applicable facility as provided in §§ 45Y(d)(4)(B)(ii) and 48E(e)(4)(B)(ii) (except as provided in § 48E(e)(4)(C))."^[5]

That parenthetical is the whole ballgame. Energy storage technology is excluded from the definition of the facilities being terminated. Batteries were not swept up with solar.

The deadlines that result are genuinely different:

Note the asymmetry in dates: solar's beginning-of-construction gate closed on July 4, 2026 — already in the past. Storage's runs to the end of 2033.

There's a second, quieter detail: standalone storage qualifies under 48E, and there is no requirement that it be paired with solar or wind.^[7] You do not need to pair a battery with solar for the credit to apply to the storage itself.

What this means if you're a homeowner

Now connect the dots to your own situation. There are exactly two paths, and they diverge sharply.

Path 1: You buy the system (cash or loan)

You are the owner, so 48E doesn't reach you — it's a business credit claimed on Form 3468, and a primary residence isn't a trade or business. Your path was 25D, and 25D is expired.

Result: $0 federal credit on solar, and $0 on a battery, in 2026.^[2][4] Your quote should not contain a 30% federal incentive line. If it does, ask what it's based on.

What you can still use: state tax credits, state and utility rebates, property- and sales-tax exemptions, SREC or performance payments where available, and net metering. Those were untouched by OBBBA and vary enormously by state.

Path 2: Someone else owns the system (lease, PPA, prepaid ESA)

Here the company holds title to the equipment. It is a business. It can claim 48E on its own return — and because storage was exempted from the termination, that claim remains available for storage far longer than for solar.

Result: the federal credit still exists in this structure — but it belongs to the system owner, not to you. Your benefit is indirect: it should show up as a lower monthly payment, a $0-down offer, or better contract terms.^[4][8]

And this is where the storage carve-out becomes commercially relevant. A lease or PPA signed in late 2026 has two components with different federal treatment:

• The solar portion — the owner's 48E claim depends on whether construction began by July 4, 2026. For projects that missed that gate, the solar credit is gone, and pricing should reflect that.
• The storage portion — the owner's 48E claim is intact, because storage was exempted. A battery added to the deal still carries credit value to the owner through 2033 construction starts.

Which means: the storage half of a 2026 lease or PPA is, perversely, the half with the stronger federal support. That is the opposite of the pre-2026 world, where batteries were usually the add-on with the weaker economics.

Five questions to ask before you sign

Because the credit belongs to the owner, whether any of it reaches you is a contract question, not a tax question. Get written answers to these:

If you're buying, what still works

The loss of 25D doesn't mean there's nothing left. It means the federal piece is gone and the local pieces matter more:

• State tax credits — several states still run their own percentage-based credit for residential solar and storage.
• Utility rebates — some utilities pay a per-watt or per-kWh incentive, often tied to a specific battery capacity or demand-response enrollment.
• Property tax exemptions — many states exempt the added home value from assessment.
• Sales tax exemptions — some states waive sales tax on equipment.
• SRECs and performance payments — available in specific markets, and they pay for generation rather than installation.
• Net metering — still the single largest variable in a system's payback. See our state-by-state net metering guide.

Because these are state- and utility-specific, the honest next step is to check what applies at your address rather than assume a national figure. Our savings calculator lets you adjust the electricity rate and incentive inputs to match your own situation.

Frequently asked questions

Can I claim the 30% credit on a battery I buy in 2026?

No. If you own the battery and it serves your primary residence, your path was Section 25D, which expired for property placed in service after December 31, 2025.^[2][3] Section 48E does cover energy storage technology, but it's claimed by the owner of a qualifying facility on Form 3468 — not on a homeowner's personal return.

So does the battery credit exist or not?

It exists, but not for you to claim directly. Section 48E still covers energy storage, and OBBBA explicitly exempted storage from the wind-and-solar termination in §48E(e)(4)(C).^[5] That means a company that owns a battery installed on your home can still claim it — and in a lease or PPA, that value is supposed to reach you through pricing. Whether it does is a contract question.

Why is storage treated better than solar?

Congress chose to terminate 48E for wind and solar facilities placed in service after December 31, 2027, with a beginning-of-construction gate of July 4, 2026. Energy storage technology was carved out of that termination by name. Storage instead keeps the original schedule: full credit value for construction starts before January 1, 2034, then a phase-down through 2035.^[5][6][7]

Can a lease or PPA still get federal credit value for the solar panels in 2026?

It depends on the project's construction start. Solar's beginning-of-construction deadline was July 4, 2026, and solar must generally be placed in service by December 31, 2027. A project that began construction before the gate can still carry the credit; one that started later cannot, and its pricing should reflect the absence of federal credit rather than assuming it. Ask for documentation — this is question 3 in the checklist above.

Will the residential credit come back?

There is no law currently restoring it. The credit was ended by statute in OBBBA, ahead of its original 2034 phase-out schedule, and planning around "it might return" is not a strategy.^[3] The reliable approach in 2026 is to work with what exists: state and utility incentives, net metering rules, and — if third-party ownership fits your situation — the storage portion of the 48E credit.

The bottom line

Three sentences, in order of importance:

1. If you buy solar or a battery in 2026, there is no federal credit. That's final under current law.
2. Section 48E still exists, still covers energy storage, and storage was explicitly exempted from the termination that closed solar's door — so a third-party owner can still claim it, through construction starts in 2033.
3. Because that credit belongs to the owner, the only way it reaches you is through contract terms. Ask the five questions above before signing anything.

And if you're weighing whether to buy at all — with no federal credit and rising retail rates — the comparison that matters is a one-time 30% discount against a compounding electricity bill. We work through that arithmetic in our guide to why your electric bill keeps rising.
