It’s 2025, and solar energy has never been more appealing—or more urgent. With electricity prices fluctuating, climate concerns growing, and clean energy solutions becoming more affordable, many homeowners are looking to the sun to power their homes. And right now, there’s a powerful financial incentive that makes this shift even more attractive: the federal solar tax credit. But how does it work? How much can you save? And what’s changing in 2025?
In this guide, we’ll walk you through everything you need to know about the solar tax credit in 2025, from who qualifies and how to claim it to tips for maximizing your savings. Whether you’re just starting to explore solar or you’re ready to install panels on your roof, understanding this credit could save you thousands.
What Is the 2025 Federal Solar Tax Credit?
At its core, the federal solar tax credit—officially known as the Residential Clean Energy Credit—is a way for the government to reward homeowners who invest in renewable energy. In 2025, this credit covers 30% of the total cost of your solar energy system, including installation. This isn’t a rebate or cash refund. Instead, it’s a dollar-for-dollar reduction in the amount of federal income tax you owe.
Let’s say your solar system costs $20,000. A 30% tax credit would reduce your federal tax bill by $6,000. That’s serious savings—just for going solar.
But this benefit may not last. While the 30% credit was originally extended through 2032, Congress is currently proposing to cut it short at the end of 2025. If that happens, systems installed in 2026 or later could miss out on this key incentive.
Who Qualifies for the Solar Tax Credit in 2025?
The good news is that the credit is widely available, but not everyone qualifies. To claim it, you must meet certain criteria.
Eligibility Requirements
First, you must own your solar energy system. If you’re leasing panels or using a power purchase agreement (PPA), you’re not eligible—the company that owns the system would get the credit instead.
You also need to have the system installed and operational by December 31, 2025, to qualify. That means the sooner you start the process, the better, especially if installation schedules fill up as the deadline nears.
What Systems Are Covered?
The credit applies to more than just solar panels. It includes:
-
Solar photovoltaic (PV) systems
-
Battery storage systems (even standalone batteries, as of 2023)
-
Inverters, racks, and wiring
-
Labor and permitting costs
-
Sales tax on eligible items
This comprehensive approach makes it easier for homeowners to invest in not just panels but also the infrastructure that supports long-term solar energy use.
How Much Can You Save with the Solar Tax Credit?
There’s no cap on how much you can claim, which is part of what makes this credit so powerful.
If your system costs $15,000, your credit would be $4,500. A larger $40,000 system would net a $12,000 credit. The more you spend on qualifying solar equipment and installation, the more you save.
However, your actual savings depend on your tax liability. The credit can only offset the taxes you owe. If your credit is larger than your tax bill, the unused amount rolls forward to future years, allowing you to continue reducing your taxes as long as the credit remains in effect (currently through 2034).
How to Claim the Solar Tax Credit
Claiming your solar tax credit isn’t difficult, but it does require some attention to detail. You’ll need to complete IRS Form 5695 when you file your federal income taxes for the year your system is installed. After calculating your credit on the form, the amount is entered on your regular tax return.
To make this easier, hold on to all your invoices, receipts, and contracts related to your solar project. You’ll want detailed documentation of the system cost, including equipment, labor, and any soft costs like permitting or inspections.
While many homeowners handle the filing themselves, it’s a good idea to consult a tax professional, especially if you’re combining the solar credit with other incentives or if your tax situation is complex.
Financing Options and the Tax Credit Impact
Going solar often involves a significant upfront investment, but you don’t necessarily have to pay cash. Many homeowners finance their systems with solar loans, and the good news is, these loans still allow you to claim the tax credit.
Combo Loans vs. Re-Amortizing Loans
A combo loan splits your financing into two parts: a main loan and a smaller “bridge loan” equal to your expected tax credit. This bridge loan typically comes due in about 12 to 18 months, just enough time for you to claim the credit and pay it off. If you don’t pay it in time, the balance rolls into your main loan, increasing your monthly payments.
Alternatively, a re-amortizing loan covers the full system cost but allows you to make a lump-sum payment after receiving your tax credit. Your lender then recalculates your monthly payment based on the reduced balance. This option is great for homeowners who may need a couple of years to use their full tax credit due to limited tax liability in one year.
Both types of loans help you reduce your monthly payments and see a quicker return on your solar investment.
What Costs Are Covered by the Tax Credit?
Understanding what qualifies is crucial for maximizing your credit.
Eligible Expenses
The 30% federal tax credit applies to:
-
Solar PV panels and related hardware
-
Battery storage systems
-
Labor and installation
-
Sales tax
-
Permitting and inspection fees
This makes the credit especially useful for full-system installations with modern battery backup, allowing for energy independence during outages or peak pricing periods.
What’s Not Covered?
Some expenses, like roof replacements, don’t qualify—unless the roof itself is solar (such as solar shingles). Similarly, electrical panel or wiring upgrades needed to support your system aren’t covered by this credit, though other incentives might help offset those costs.
Can You Combine the Federal Credit with Other Incentives?
Absolutely—and you should. Stacking incentives from state or local governments can significantly lower your out-of-pocket expenses before you apply the 30% federal credit.
For example, if your state offers a $500 rebate on a $20,000 system, you’ll calculate the federal credit based on the remaining $19,500. That gives you a $5,850 federal credit, on top of your state rebate.
Just be sure to apply local incentives first, as the federal credit is calculated on the net system cost after those are deducted.
Why Now Is the Time to Act
One of the most urgent reasons to go solar in 2025 is the uncertainty surrounding the future of the tax credit. While it was initially extended through 2032, a proposal in Congress—dubbed the “Big Beautiful Bill”—could end the 30% incentive after December 31, 2025.
If that happens, homeowners who delay their installation could miss out entirely. This makes 2025 a critical window for locking in maximum savings.
Beyond the tax break, installing solar now can also lower your monthly utility bills, increase your home’s resale value, and help reduce your carbon footprint. It’s a financial and environmental win-win.
Frequently Asked Questions
Is the ITC transferable or sellable?
No. According to the IRS, the federal solar tax credit cannot be transferred or sold to another party. It must be claimed by the homeowner who paid for and owns the solar system.
Can I carry forward unused credit?
Yes. If your tax credit is more than your federal tax liability, you can roll over the remaining balance into future tax years, as long as the credit is still active.
What if I don’t owe taxes this year?
Since this is a non-refundable credit, it only applies if you owe taxes. If your current tax liability is zero, you won’t receive any immediate benefit. However, the unused credit can still roll forward to future years when you do owe taxes.
If you’re retired or don’t expect to have significant taxable income in the future, it’s smart to consult a tax advisor to explore your options.
Final Thoughts: Make the Most of Solar Savings in 2025
The federal solar tax credit is one of the most generous and effective tools available for making clean energy more affordable. By offering a 30% credit on the cost of installing a solar energy system—including batteries—it significantly reduces the upfront cost and speeds up your return on investment.
