Homeowners can't claim the federal residential solar tax credit for a system installed in 2026. The IRS ended the Residential Clean Energy Credit under Section 25D for expenditures made after December 31, 2025. A separate business credit under Section 48E may still be available to an eligible company that owns a solar system and leases it to a homeowner, subject to federal rules and deadlines. That distinction matters when you're comparing solar offers. Some advisers help you find public incentives. Others work for installers, lenders, or solar companies that earn money from the deal. Start with free government resources, then pay for professional advice if your situation calls for it. This guide explains which credit may apply, where to look for reliable help, and what to check before signing a contract.
Which Investment Tax Credit Applies to Homeowners Now?
For a solar system placed in service in 2026, the homeowner can't claim the former residential credit. The business credit belongs to the company that owns the equipment, if the project qualifies. In a lease or power purchase agreement (PPA), that company is usually the solar provider.
Residential credit vs. business credit
Question | Residential credit (§25D) | Business credit (§48E)
|
Who claims it | The homeowner who paid for and owns the system | The owner of the equipment, such as a leasing or PPA company |
Status for installs completed in 2026 | Ended (expenditures after Dec 31, 2025) | Available to eligible owners, subject to rules below |
Rate as IRS states it | Not applicable for 2026 installs | 6% base; 30% if PWA requirements are met or an exception applies, including qualified facilities under 1 MW AC or construction begun before Jan. 29, 2023; bonuses possible |
Solar deadline | Not applicable | Projects starting construction after July 4, 2026 must be placed in service by Dec 31, 2027 |
Leased solar water heating or small wind | Not applicable | Denied when leased to a third party (§48E(i)) |
How a homeowner benefits | Not applicable | Only through contract pricing, if the company passes any value on |
The installation date matters. The IRS says the residential credit doesn't apply to property placed in service after December 31, 2025. Paying a deposit in 2025 won't qualify a system that wasn't fully installed and ready for use until 2026. The business credit has its own rules. Under IRS Notice 2025-42, certain wind and solar projects that begin construction after July 4, 2026, must be placed in service by December 31, 2027, to qualify. Other requirements can apply, so a homeowner shouldn't assume a solar provider automatically qualifies for the credit.
The law also treats some leased equipment differently. Section 48E(i) denies the credit for certain leased solar water-heating property and small wind property. That provision names those categories, not rooftop solar electric panels. Much of the confusion in sales pitches comes from the One Big Beautiful Bill changes. The homeowner credit ended, but a business credit may still be available under separate rules. If a salesperson mentions a 30% credit, ask who claims it and whether the contract reflects any of its value. Don't assume the company will pass the full benefit to you.
What Do Subsidy-Advising Services Cover, and How Are They Paid?
Most solar incentive help comes from four places: free public resources, credentialed tax professionals, installer or lender sales teams, and paid incentive consultants. Each has a different role. Knowing who pays the adviser can help you judge whether the advice is independent.
Compare the main types of help
Provider type | What it covers | How it's usually paid | What it can't do
|
Free public tools (IRS.gov/HomeEnergy, DSIRE, state energy office) | Which credits and programs exist and their rules | Free | Apply rules to your tax return |
CPA, enrolled agent, or tax attorney | Whether a credit applies to you and how it's reported; IRS representation | Flat or hourly fee (get it in writing) | Sell or finance equipment |
Installer or financing company sales team | Quotes, loan or lease terms, program paperwork the company handles | Built into the system price or financing | Give independent tax advice |
Paid incentive consultant | Program research and applications, often for businesses | Engagement or contingency terms (ask) | Provide full IRS representation without an attorney, CPA, or enrolled-agent credential |
Start with the free options. The IRS's home energy credit information explains the federal rules. The DSIRE database lists state and local incentives for renewable energy and efficiency. It provides a useful overview, but its own guidance says to verify details with the agency running each program. Your state energy office is another place to check. The U.S. Department of Energy's State Energy Program supports state energy offices, and the National Association of State Energy Officials maintains a directory to help you find yours. State and utility programs may still matter for a 2026 installation, even though the federal homeowner credit has ended. Check the state incentives available in your area before paying someone to search for them.
When should you pay for professional advice?
A tax professional may help if you're amending a return, carrying forward a credit from an eligible 2025 installation, or reviewing a complex contract. An incentive consultant may also assist with specific program applications. Before paying, ask what the service covers, whether it includes eligibility checks, application support, contract reviews, or IRS representation, and get the fee in writing. For full IRS representation, choose an attorney, CPA, or enrolled agent. Verify credentials through the relevant state licensing board or IRS directory. Avoid tax preparers who charge a percentage of your refund, which the IRS warns against.
If Outages Are the Real Worry: A Separate Backup Budget (EcoFlow TITAN 5000 Classic)
Advisory fees and backup equipment are separate expenses. If outages are a concern, keeping your refrigerator cold, lights on, and router running may matter more than tax credits. Start by listing the essential 120V devices you need to power, then budget for the battery, compatible panel, and installation separately. A storm or utility shutoff can quickly show which devices your household relies on most. The EcoFlow TITAN 5000 Classic is designed to power selected 120V essentials, including a refrigerator, router, and lights. It can recharge from an AC outlet or compatible solar panels connected directly to its solar input within the input specifications. AC coupling with an existing rooftop solar array requires the 120V EcoFlow Smart Home Panel 10 and a CT sensor, with installation by a licensed electrician. A conventional grid-connected rooftop array shuts down during an outage and cannot keep charging the battery through that existing connection. For solar recharging during an outage, use compatible panels connected directly to the battery's solar input. Keep this backup setup separate from solar financing or tax advice.
Set a separate budget for backup power
Keep backup equipment and installation costs separate from solar financing and tax advice. Request written quotes for each item, and check whether your existing solar panels can work with the battery.

The EcoFlow TITAN 5000 Classic has a capacity of 5,017.6Wh, providing around 4,265Wh of usable energy after accounting for an estimated 15% conversion loss. A refrigerator, router, LED lights, and phone and laptop charging could use about 2,200Wh per day, giving you roughly 1.9 days of backup power before recharging. Actual runtime depends on your appliances and usage, while solar recharging varies with sunlight and weather. To estimate your needs more accurately, list the devices you want to power and their daily energy use. This will help when sizing a home backup battery.
How Do Leases, PPAs, and Loans Change Who Gets the Credit?
Buying a system with cash or a solar loan makes you the owner, but a 2026 installation doesn't qualify for the former residential credit. With a lease or PPA, the company owns the equipment and may qualify for the business credit if it meets the applicable rules. Whether any of that value reaches you depends on the contract.
Path | Who owns the system | Who can claim a credit for a 2026 install | Key contract questions
|
Cash purchase | You | No residential credit | Warranty, workmanship, permit and interconnection handling |
Solar loan | You (lender holds a lien or note terms) | No residential credit | Right to cancel, deadline, total cost over the term |
Lease | Leasing company | Company, if eligible under §48E | Payment escalator, early termination fees, who keeps credits and RECs |
PPA | PPA company | Company, if eligible under §48E | Price per kWh and escalator, termination, who keeps credits and RECs |
The Federal Trade Commission says some PPA providers may offer lower rates because they claim the tax credits and incentives, but the benefit passed on to homeowners varies. Ask the company to explain its pricing and put in writing who receives the credits, other incentives, and renewable energy certificates. Check whether the quoted lease price assumes a credit the company hasn't secured, since business credits have construction and installation deadlines. A sales quote alone doesn't prove eligibility. Ownership also affects maintenance, home sales, and end-of-contract terms, so review the trade-offs of leasing versus buying solar and compare the actual contracts.
Which Questions Should You Ask Before Paying an Adviser or Signing a Contract?
Ask who claims each credit, who pays the adviser, and what credentials the adviser holds. Get the answers in writing. If someone promises a government check or guarantees a tax credit without checking your situation, pause before signing.
Use this checklist before you commit
Before signing a contract or paying an adviser, check the details carefully. These questions can help you spot unclear terms, hidden costs, and potential conflicts of interest.
Who claims the federal credit, and does the contract say so?
Does the quoted price depend on a credit the company still needs to qualify for?
Does the adviser work for you, an installer, or a lender?
Is the tax adviser a CPA, enrolled agent, or attorney?
Are there annual payment increases, early termination fees, or cancellation deadlines?
Have you compared detailed bids from several companies?
Watch for these red flags
Be cautious if a salesperson or adviser:
Promises a government tax rebate check in the mail.
Promises a credit even when you don't qualify.
Charges a tax preparation fee based on a percentage of your refund.
Pressures you to sign the same day.
Won't explain who receives the tax credit or how the contract price is set.
You can report suspected solar scams through ReportFraud.ftc.gov. For financing complaints, the Consumer Financial Protection Bureau can help direct consumers to the appropriate process. If a tax adviser is involved, verify the person's credentials and ask for a written description of the work they'll perform. Finally, compare each offer side by side. Comparing solar quotes can help reveal differences in ownership, payment increases, fees, and assumed incentives that may be easy to miss in a sales presentation.
Conclusion
The federal residential solar investment tax credit ended for new systems placed in service after 2025. A business credit may still be available to an eligible system owner, but homeowners shouldn't assume that value will lower their price. Start with free government resources, confirm the rules with a credentialed tax professional when needed, and get credit terms in writing before signing. If outages are your main concern, budget for backup power separately. The EcoFlow TITAN 5000 Classic may fit a household that needs selected 120V essentials to keep running, paired with the compatible 120V EcoFlow Smart Home Panel 10 installed by a licensed electrician. Get written quotes for the equipment and installation, then compare the setup with your actual list of essential devices.
FAQs
Is the 30% solar investment tax credit still available to homeowners?
No. The federal residential credit ended for expenditures made after December 31, 2025. A homeowner with a qualifying system completed in 2025 may still be able to claim the credit on the 2025 return, but a deposit paid in 2025 doesn't qualify a system completed in 2026.
Can a solar leasing company still claim a tax credit on my roof?
It may qualify for the business credit under Section 48E if the project meets the federal rules and deadlines. The homeowner doesn't claim that credit. Any financial benefit passed to the homeowner depends on the contract and pricing.
Do I have to pay someone to find solar incentives?
No. Start with IRS.gov/HomeEnergy, DSIRE, and your state energy office. These resources list federal, state, and local programs. A credentialed tax professional can help determine how a tax rule applies to your return.
Which adviser fee arrangements should make me cautious?
Be wary of tax preparers who charge a percentage of your refund, since the IRS warns against this practice. Also ask whether an adviser receives money from an installer or lender. You should know who pays them before relying on their recommendation.
Does a backup battery I buy separately qualify for the investment tax credit?
Don't assume it does. The former residential credit for home batteries ended for expenditures after 2025. Check the rules for any other program that may apply, and ask a qualified tax professional before making a purchase.
