The Federal Battery Tax Credit Is Gone, Here's What Still Helps

For nearly a decade, a homeowner buying a battery could count on the federal government covering 30 percent of the cost through a tax credit. As of January 1, 2026, that specific credit is gone for anyone paying cash or financing a system with a loan, and the payback math on a home battery has shifted as a result.

You cannot escape this reality

My name is Porter Stansberry.

I'm the founder of one of the largest independent financial research firms in the world. Over the last 30 years we've helped hundreds of thousands of Americans navigate almost every major economic cycle.

We've been on the forefront of every big financial story – from the collapse of Fannie Mae and Freddie Mac to the rise of Bitcoin, the COVID inflation surge, and the artificial intelligence revolution.

But today, I need to expose a story the likes of which we haven't seen in half a century.

In fact, the last – and only – time this happened was 1974. A secret deal struck in a Saudi desert that quietly determined the financial fate of an entire generation of Americans.

It created extraordinary wealth for some, while casting millions more into relative poverty.

Now, 52 years later, it's happening again.

And as you'll see, the aftershock of this event could reset not just your personal wealth, but the entire foundation of the U.S. dollar.

How you save, how you invest, how you protect everything you've built… it's all being reshaped by what Fortune calls "the biggest change to the world's relationship with the dollar" in a generation.

Yet almost nobody is prepared for it.

So if you've been watching the chaos of the past year unfold, struggling to make sense of it all – you're about to get the answers you've been searching for.

Everything from the government taking direct equity stakes in tiny mining companies… to Trump's obsession with Greenland… his strange deals with Elon Musk, Jeff Bezos, Sam Altman and Mark Zuckerberg… the re-opening of shuttered nuclear plants… and a $12 billion stockpile of obscure metals most Americans have never heard of…

It's all deeply and inexorably connected to an inescapable fact no-one has prepared you for:

Trump is replacing the dollar.

His shocking money reset has bypassed all conventional channels – enacted instead through a series of executive orders, bi-lateral deals and a landmark treaty signed by 13 nations in December 2025 (barely reported in the press) called Pax Silica.

You need to know that the financial decisions you make in the face of Trump's New Dollar could dictate whether you're enriched, or quietly impoverished by the seismic shift already underway.

The stocks to buy. The assets to avoid. And the critical moves our research indicates you should make to ensure you and your family end up on the right side of this once-in-a-generation wealth divide…

It's all laid out here for you in my important new briefing.

Good investing,

What Actually Changed

The Residential Clean Energy Credit, known formally as Section 25D, offered a 30 percent federal tax credit on solar and battery storage systems purchased outright. Legislation signed in July 2025 terminated that credit nearly a decade ahead of its originally planned 2034 expiration, ending it for any system purchased starting in 2026. Anyone who managed to fully purchase, install, and commission a qualifying battery before the December 31, 2025 deadline can still claim the credit on this year's tax filing, but new purchases in 2026 no longer qualify.

This doesn't mean every incentive disappeared. A separate credit, Section 48E, still applies to systems owned by a third party, meaning homeowners who go the solar lease or power purchase agreement route can still access a version of that federal benefit indirectly through the company that owns the system, and that pathway remains available through 2032. State-level incentives, utility rebates, and virtual power plant enrollment payments are also unaffected by this specific change and remain active in the states that offer them.

The practical effect is that the upfront cost of owning a battery outright just went up by roughly the amount that credit used to cover, while a lease or PPA arrangement became comparatively more attractive for homeowners specifically motivated by minimizing upfront cost. Anyone who was already planning a battery purchase this year has a real financial reason to move up that timeline where possible, and anyone starting the process fresh should factor the credit's absence directly into their cost comparison between owning and leasing.

The Hardware Stack:

Tesla Powerwall: A residential battery commonly purchased outright, now without the federal 30 percent credit that previously applied to that purchase path.

Sunrun: A solar and battery installer offering lease and power purchase agreement options that can still indirectly access the Section 48E federal credit.

Generac PWRcell: A home battery system available through both direct purchase and third-party ownership arrangements, now weighed differently under the new tax rules.

Vulnerability Score

Outdated cost assumptions: A homeowner budgeting for a battery based on older articles or quotes may not realize the 30 percent federal credit no longer applies to a 2026 purchase.

No comparison between ownership models: Skipping a direct comparison between buying outright and a lease or PPA now means missing a real cost difference that didn't exist as starkly before this year.

Missed state and utility incentives: State rebates and virtual power plant payments are unaffected by the federal change, but many homeowners don't check whether their state has its own program to help offset the gap.

What This Means for Anyone Planning a Purchase

None of this makes a home battery a bad investment, backup power and other advantages haven't changed. But the federal financial picture has genuinely shifted, and pretending otherwise means starting a cost comparison with outdated numbers.

Anyone in the middle of planning a purchase should get an updated quote reflecting current 2026 incentive rules specifically, rather than relying on cost estimates from even a year ago, and should ask directly about lease and PPA options if minimizing
