Residential Clean Energy Credit 2026: What Homeowners Need to Know
Residential Clean Energy Credit 2026: What Homeowners Need to Know
The residential clean energy credit 2026 is no longer available for new qualifying residential clean energy property. The federal Residential Clean Energy Credit under Section 25D ended on December 31, 2025, so eligible property installed after that date does not receive the former 30% federal tax credit.
Prior-year unused credits may still be carried forward, and state, utility, local, or manufacturer incentives may still reduce project costs.
Is the Residential Clean Energy Credit Available in 2026?
No. The residential clean energy credit 2026 does not apply to new qualifying residential clean energy property installed after December 31, 2025.
For homeowners, the main points are:
-
New 2026 installations: The former 30% Section 25D credit is no longer available.
-
Unused prior-year credits: Eligible amounts from 2025 or earlier may still be carried forward under applicable tax rules.
The IRS also states that the Residential Clean Energy Credit is nonrefundable and that eligible unused amounts can be carried forward to reduce tax owed in future years.
What Was the Section 25D Tax Credit?
The Section 25D tax credit, formally known as the Residential Clean Energy Credit, provided a 30% credit for qualifying residential clean energy expenditures during the 2022–2025 period, subject to applicable eligibility requirements.
The credit directly reduced federal income tax liability but was nonrefundable. Historically, qualifying property included solar electric systems, battery storage, geothermal heat pumps, small wind systems, and qualified fuel cells.
For 2026 purchase decisions, homeowners do not need to analyze Section 25D technology rules in detail unless they are reviewing a prior-year claim. The more important questions are when the system was installed, who owns it, and what other incentives remain available.
How Does the Residential Clean Energy Credit Expiration Affect 2026 Projects?
A simple rule for budgeting is: do not subtract the former 30% federal tax credit from the price of a system installed in 2026.
Solar and Battery Storage
A homeowner-owned solar system installed in 2026 does not qualify for the former Section 25D credit. The same applies to battery storage: a qualifying battery installation completed in 2026 does not qualify for the former 30% Section 25D federal tax credit.
Battery storage can still provide value independent of a federal tax incentive. A home battery backup may provide outage protection, support energy management, or help shift electricity use away from higher-rate periods where applicable.
For homeowners prioritizing outage resilience, the Anker SOLIX E10 Whole-Home Backup combines battery storage, solar integration, and optional generator support in a scalable system. Capacity can expand from 6 kWh to 90 kWh, while configurations deliver 10–30 kW of turbo output and support 9–27 kW of solar input. With the Power Dock, automatic backup switching occurs in 20 ms or less, making E10 especially suitable for larger homes, central air conditioning, extended outages, and households seeking flexible whole-home backup.
Other Clean Energy Technologies
The same 2026 treatment applies to geothermal heat pumps, small wind systems, and qualified fuel cell property previously covered by Section 25D.
Why Does the Installation Date Matter?
Paying a deposit, signing a contract, purchasing equipment, and completing installation can occur on different dates.
For Section 25D, this distinction is particularly important for projects spanning 2025 and 2026. IRS guidance explains that an expenditure is generally treated as made when the original installation is completed. Paying for equipment before December 31, 2025, does not preserve the credit if installation is completed afterward.
For a project near the deadline, keep:
-
Final invoices
-
Proof of payment
-
Installation records
-
Inspection documents
-
Utility approval or permission-to-operate records
If a homeowner paid for solar in 2025 but installation was not completed until 2026, the 2025 payment alone does not establish eligibility for the expired credit.
What Happens to Unused Credits From 2025 or Earlier?
The expiration of Section 25D does not automatically erase an eligible credit that was generated in a prior year but could not be fully used.
The IRS states that unused Residential Clean Energy Credit amounts may be carried forward to reduce tax owed in future years.
Homeowners reviewing a possible carryforward should check:
-
The tax return for the year the original credit was generated.
-
Form 5695 and related tax records.
-
The amount of credit already used.
-
Any remaining eligible carryforward.
-
Current IRS filing instructions for the year in which the carryforward will be used.
Keep prior returns, Form 5695, contracts, invoices, payment records, and installation documentation. Because carryforward treatment depends on individual tax circumstances, homeowners should consult current IRS instructions or a qualified tax professional before filing.
Direct Purchase vs. Solar Lease vs. PPA in 2026
Ownership affects both costs and tax treatment.
|
Arrangement
|
Equipment Owner
|
What the Homeowner Should Evaluate
|
|
Direct purchase
|
Homeowner
|
Full purchase and financing cost without assuming the former 30% Section 25D credit
|
|
Solar lease
|
Leasing company
|
Monthly payment, escalators, maintenance, buyout and transfer terms
|
|
PPA
|
Energy provider
|
Electricity rate, annual increases, contract length and home-sale provisions
|
With a lease or PPA, the third-party owner may have separate tax or incentive considerations depending on the project structure and applicable law. Those benefits should not be confused with a personal homeowner Section 25D credit.
How to Assess Other Clean Energy Incentives in 2026
The end of Section 25D makes other incentives more important, but not all programs work the same way. Before comparing project quotes, identify both what the incentive is worth and how you actually receive it.
1. Search Multiple Sources
Check programs offered by:
-
State energy agencies
-
City or county governments
-
Electric utilities
-
Municipal utilities and electric cooperatives
-
Solar or battery programs
-
Equipment manufacturers
Do not rely only on an installer's advertised “net price,” because that figure may assume incentives for which a particular household does not qualify.
2. Identify the Incentive Type
Different incentives affect project economics differently.
|
Incentive
|
What to Check
|
|
Rebate
|
Whether payment comes before or after installation
|
|
State tax credit
|
Tax liability limits and carryforward rules
|
|
Utility incentive
|
Eligible equipment, installer and service territory
|
|
Performance/VPP program
|
Required battery access, participation period and compensation
|
|
Financing program
|
Interest rate, fees, term and total repayment
|
|
Manufacturer promotion
|
Eligible models, purchase dates and claim deadlines
|
3. Check Eligibility Before Counting the Savings
For each program, verify:
-
Eligible ZIP code or utility territory
-
Required equipment specifications
-
Approved installer requirements
-
Income or property restrictions
-
Application deadlines
-
Whether approval is required before purchase or installation
-
Whether the incentive applies to solar, batteries, or both
-
Whether leased systems qualify
-
Whether funds are still available
Some rebate programs have limited budgets and may close when allocated funding is exhausted.
4. Check Whether Incentives Can Be Combined
Do not assume two incentives can automatically be stacked.
Ask each program administrator whether another state, utility, local, or manufacturer incentive reduces the eligible project cost or affects the amount available. Also verify how a rebate or other incentive may affect federal or state tax treatment.
5. Compare the Net Cost Only After Verification
A more useful comparison is:
Project price + applicable financing costs – confirmed incentives = estimated total project cost
Separate confirmed incentives from estimated or conditional savings when comparing quotes.
What Should Homeowners Check Before Buying in 2026?
Before signing a clean energy contract, use this short checklist:
-
Ownership: Who legally owns the solar or battery equipment?
-
Installation date: When will installation actually be completed?
-
Total cost: What are the equipment, labor, financing, maintenance, and replacement costs?
-
Confirmed incentives: Which rebates or credits have been verified with the administering program?
-
Utility value: Can the system participate in time-of-use, demand-response, or virtual power plant programs?
-
Contract terms: Are there escalators, transfer requirements, buyout fees, or long-term obligations?
-
Tax treatment: Does any claimed tax benefit apply to the homeowner or to a third-party owner?
Request important incentive claims in writing, particularly when an advertised project price depends on a tax benefit or rebate.
Residential Clean Energy Credit 2026: Key Takeaways
The Residential Clean Energy Credit is no longer available for qualifying residential clean energy property installed after December 31, 2025. Homeowners considering solar, battery storage, geothermal, wind, or fuel-cell systems should therefore evaluate 2026 projects without automatically deducting the former 30% Section 25D credit.
However, eligible prior-year credits may still be carried forward, and state, local, utility, or manufacturer incentives may remain available. Because incentive programs and tax rules can change, verify current requirements directly with the IRS, the relevant program administrator, utility, or a qualified tax professional before making a purchase or filing a return.
Frequently Asked Questions About the Residential Clean Energy Credit in 2026
Is the Residential Clean Energy Credit available in 2026?
No. The federal Residential Clean Energy Credit under Section 25D ended on December 31, 2025. Qualifying residential clean energy property installed after that date does not qualify for the former 30% federal tax credit. Other state, local, utility, or manufacturer incentives may still be available.
When did the Section 25D tax credit expire?
The Section 25D Residential Clean Energy Credit expired on December 31, 2025. IRS guidance states that expenditures treated as made after that date do not qualify for the credit. For installation projects spanning 2025 and 2026, homeowners should verify when the original installation was actually completed.
What if I paid for solar in 2025 but the system was installed in 2026?
Paying for the system in 2025 does not by itself preserve the Section 25D credit. IRS guidance generally treats the expenditure as occurring when the original installation is completed. If installation was completed after December 31, 2025, the prior payment date does not make the project eligible.
Can unused Residential Clean Energy Credits from 2025 be carried forward?
Yes, eligible unused Residential Clean Energy Credit amounts from a prior year may generally be carried forward to reduce tax owed in future years. Homeowners should review their prior Form 5695, tax returns, and current IRS instructions to determine the amount available and its proper filing treatment.
Do solar leases and PPAs qualify for the homeowner tax credit?
Generally, the homeowner does not claim the Section 25D credit for equipment owned by a solar leasing company or PPA provider. The third-party owner may be subject to different tax and incentive rules. Homeowners should instead compare contract rates, escalators, maintenance obligations, buyout options, and home-sale provisions.
