Solar Tax Credit 2026: What Remains After Section 25D Ends

The solar tax credit 2026 changes the economics of buying solar and batteries in the United States. With Section 25D no longer available for new 2026 residential installations, homeowners need to evaluate solar and batteries without assuming the former 30% federal credit.

Other opportunities remain, however, including state incentives, utility rebates, export credits, and battery programs. Eligible commercial and third-party projects may also have Section 48E opportunities, subject to project-specific eligibility, timing, and other applicable restrictions.

Quick Answer: Is There a Solar Tax Credit in 2026?

For homeowners, the Section 25D Residential Clean Energy Credit is no longer available for expenditures made after December 31, 2025. Paying in 2025 does not preserve the credit when original installation is completed after the deadline. However, not every solar incentive disappeared.

Eligible commercial or third-party projects may qualify under Section 48E, while homeowners may still find state tax benefits, utility rebates, net-billing credits, battery incentives, and VPP payments. Because each program has different rules, verify the program, equipment, ownership, and deadline before including any incentive in a solar quote.

What Happened to the Federal Solar Tax Credit in 2026?

Section 25D previously provided a 30% Residential Clean Energy Credit for qualifying residential solar and battery expenditures through 2025. The credit now terminates for expenditures made after December 31, 2025. For projects near the cutoff, installation timing—not simply the payment date—is critical.

The installation date matters more than the payment date

The IRS states that an expenditure is generally treated as made when the item's original installation is completed. Therefore, signing a contract or paying in December 2025 does not preserve Section 25D if installation is completed in 2026. An eligible installation completed in 2025, however, may still support a 2025 credit claimed on a return filed in 2026.

Use project records to establish your timeline

If your project crossed the 2025–2026 boundary, keep the signed contract, itemized invoices, installation completion records, inspection documents, interconnection records, and Permission to Operate. PTO may help document the timeline but is not automatically the federal tax test. Eligible prior-year residential credits are generally claimed using IRS Form 5695.

Section 25D vs. Section 48E: Know Which Rule Applies

The end of Section 25D does not mean every federal clean-energy incentive ended. Section 48E remains relevant to certain qualifying clean-electricity investments, but it has different taxpayer and project requirements, as well as additional timing and eligibility restrictions under current law. Homeowners should not treat it as a replacement residential credit.

Section 25D ended for new residential expenditures

For a new homeowner installation in 2026, do not subtract an assumed Section 25D credit from the purchase price.

Section 48E follows separate commercial rules

Section 48E covers qualifying clean-electricity facilities and energy storage technology. The Section 48E credit generally has a 6% base rate and may increase to 30% when applicable prevailing-wage and apprenticeship requirements are met or when a qualifying exception applies, with additional bonuses potentially available for certain projects.

Buying vs. Leasing Solar in 2026: Who Gets the Incentive?

Ownership is especially important when evaluating solar incentives in 2026 because the system owner differs depending on whether you buy, lease, or enter into a PPA. Instead of choosing based on who can advertise a federal incentive, compare who owns the system and what you will actually pay.

A solar loan does not change ownership

A conventional solar loan finances a homeowner-owned system, so it does not restore Section 25D for a new 2026 installation. When comparing financing, request both the cash and financed price, then check the APR, financing or dealer fees, term, and total repayment—not just the advertised monthly payment.

Leases and PPAs require a contract comparison

With a lease, you pay to use third-party-owned equipment; with a PPA, you generally buy the electricity it produces. A third-party owner may qualify for applicable commercial incentives if the taxpayer and project meet all relevant requirements. Before signing, compare the starting payment or rate, annual escalator, total contract term, buyout price, maintenance responsibility, and home-sale transfer requirements.

What Solar and Battery Incentives Can Homeowners Use in 2026?

Without Section 25D for new residential expenditures, homeowners should build their savings estimate from programs actually available at their address. State incentives, utility programs, export compensation, and VPP payments work differently, so calculate each separately rather than using a generic “government incentives” figure.

Check state tax credits and exemptions

State incentives may include an income-tax credit, sales-tax exemption, or property-tax exemption, each affecting costs differently. Check your state revenue department and energy agency and record the exact program name, eligible technology, benefit, maximum amount, expiration date, and application process. Confirm separately whether batteries qualify.

Check utility rebates before installation

Utility rebates may depend on your address, equipment, installer, income, or application date, and some programs have limited funding. Before buying, verify:

• whether your service address qualifies;
• whether the proposed equipment is approved;
• whether preapproval is required;
• the current rebate amount; and
• whether funding remains available.

California's Self-Generation Incentive Program (SGIP) is one example of a program offering incentives for qualifying distributed energy resources, including battery storage. It is not a nationwide benefit, and California customers should verify their specific eligibility category and current program availability before treating SGIP as a purchase discount.

Calculate net-billing value from your actual tariff

Net metering or net billing compensates exported solar electricity through utility bill credits rather than a tax credit. Check your utility's current import rate, export rate, time-of-use periods, and fixed charges. These figures show whether using solar directly—or storing it for later—may be more valuable than exporting excess production.

Verify VPP payments before counting them

Virtual Power Plant programs may compensate eligible battery customers for making stored energy available during selected grid events. Before adding VPP revenue to your ROI calculation, confirm battery compatibility, utility territory, dispatch frequency, minimum backup reserve, opt-out rules, and payment formula. If eligibility is uncertain, use $0 VPP income in your base-case calculation.

Does a Home Battery Still Make Sense Without Section 25D?

Without the former 30% residential credit, a battery should be evaluated according to what it actually provides. For many households, potential value may come from outage protection and shifting electricity use, with verified utility or VPP payments treated as an additional benefit rather than guaranteed savings.

Start with the loads you need during an outage

List the appliances you want powered during an outage—such as refrigeration, lights, Wi-Fi, office equipment, pumps, or HVAC—before choosing capacity. When comparing a home battery backup, match those loads against usable capacity, continuous and surge output, 120V/240V support, transfer behavior, solar input, and expansion capability.

Calculate whether storing solar beats exporting it

For example, if your utility pays $0.08/kWh for midday exports but charges $0.35/kWh during evening hours, storing excess solar may be more valuable than exporting it. Calculate the difference using your actual tariff, then account for battery round-trip efficiency, usable capacity, degradation, and how often your household can realistically cycle the battery.

Match backup capacity to your home's needs

For homeowners who need to keep high-demand essentials running during an outage, the Anker SOLIX E10 Whole-Home Backup supports 120/240V split-phase loads and can start a 5-ton central A/C. Its 7.68kW continuous output can support multiple household loads, while a single E10 system can scale to 30kWh for longer outages. Homes with greater backup needs can expand a Power Dock system to 90kWh, while ≤20ms switchover provides automatic backup when grid power fails.

How to Verify a Solar or Battery Quote Before You Sign

A credible 2026 proposal should work without unsupported tax credits or rebates. Rebuild the seller's estimate using the actual cash price, financing costs, verified incentives, your utility tariff, expected production, and contract obligations rather than relying solely on the advertised monthly savings.

1. Build an incentive verification sheet

Record every incentive separately instead of accepting a combined “government savings” figure.

If the seller cannot identify the official program or explain why your project qualifies, mark the incentive unverified and remove it from your base calculation.

2. Calculate the project without uncertain incentives

For an owned system, start with the applicable cash or financed price and account separately for any additional financing costs, then subtract only verified incentives. Estimate solar savings from actual utility rates. For storage, keep electricity savings, backup value, and verified program payments separate rather than combining them into one optimistic “lifetime savings” figure.

3. Run a conservative scenario

Recalculate the quote with lower production, no unverified incentives, the actual loan or contract escalator, and conservative electricity-price assumptions. For leases and PPAs, also calculate the cost if you sell the home before the contract ends. If the project only works under optimistic assumptions, reconsider the price or structure.

Conclusion: Navigate Solar Incentives in 2026 After Section 25D

The end of Section 25D changes how homeowners should evaluate solar and storage in 2026, but it does not eliminate every source of value. Start with the actual installed cost and add only incentives verified for your address, equipment, and ownership structure.

Base the final calculation on verified local incentives and your actual utility rates. If the economics still work under conservative assumptions, you have a much stronger basis for deciding whether to buy.

Frequently Asked Questions About the Solar Tax Credit 2026

Is there a federal solar tax credit for homeowners in 2026?

Section 25D cannot be claimed for residential clean energy expenditures made after December 31, 2025. IRS guidance also states that advance payment does not preserve the credit when original installation is completed after the deadline. Homeowners with projects near the cutoff should verify the installation timeline and retain supporting documentation.

Can a solar lease or PPA receive a federal incentive in 2026?

Potentially. An eligible third-party owner may qualify for Section 48E when the taxpayer and project satisfy applicable requirements, including current timing and other eligibility restrictions, but the homeowner normally does not claim that credit. Ask the provider which incentive it expects to receive and whether its value is reflected in your lease payment or PPA rate.

Are battery incentives still available in 2026?

Yes, depending on location and ownership. Homeowners may find state rebates, utility storage incentives, or VPP payments, while qualifying storage projects may be eligible for Section 48E when the taxpayer, project, and equipment satisfy applicable requirements. Verify the exact battery model, customer eligibility, available funding, application deadline, and preapproval requirements before including an incentive in your budget.

Is solar still worth it without the 30% federal tax credit?

It can be, but use project-specific numbers. Compare installed cost, financing, expected production, import and export electricity rates, and verified local incentives. Run the calculation again with uncertain incentives removed. If the project still produces acceptable savings under conservative assumptions, the financial case is much more credible.
