Solar Power Tax Credit in 2026: How Loans, Leases, PPAs, and PACE Really Compare
The federal residential solar tax credit ended for systems placed in service after December 31, 2025. That change affects homeowners choosing solar financing in 2026. Buying panels with cash, taking out a solar loan, signing a lease, or using a power purchase agreement (PPA) won't give you a new federal homeowner credit for a system completed this year. That doesn't make the financing choice any less important. Some solar loans were designed around a 30% tax credit that borrowers could use to pay down their balance. Without that money, monthly payments may rise under the loan terms. Before signing, compare the total cost, who owns the equipment, and what happens when you sell your home. We'll also cover PACE financing and how to budget separately for outage backup.
Can Any Solar Financing Option Still Earn a Homeowner a Tax Credit in 2026?
No. The federal Residential Clean Energy Credit is no longer available for systems placed in service after December 31, 2025. Homeowners who own a qualifying system completed in 2025 may still claim the credit on their 2025 tax return, subject to the applicable rules. Lease and PPA customers don't claim the equipment owner's credit.
Financing type | Who owns the system | Who could claim a federal credit | Status for a 2026 installation
|
Cash purchase | Homeowner | Homeowner (Section 25D) | Ended for property placed in service after Dec. 31, 2025 |
Solar loan | Homeowner | Homeowner (Section 25D) | Ended for property placed in service after Dec. 31, 2025 |
Lease (monthly or prepaid) | Leasing company | The owner, not the homeowner | Homeowner claims nothing; owner follows business credit rules |
PPA | PPA company | The owner, not the homeowner | Homeowner claims nothing; owner follows business credit rules |
PACE | Homeowner (repays through property tax bill) | Homeowner (Section 25D) | Ended for property placed in service after Dec. 31, 2025 |
The IRS ties eligibility to when the installation is complete, not when you pay a deposit or sign a contract. A payment made in 2025 won't qualify a system that wasn't placed in service until 2026. Review the IRS residential clean energy credit rules before relying on a sales representative's explanation.
Business tax credits follow different rules from the former homeowner credit. If a lease or PPA salesperson mentions a 30% business credit, ask how the company handles that benefit and whether it affects your contract price. Don't assume the company will pass any tax benefit on to you. Since financing won't restore the expired homeowner credit, the next step is to compare ownership, payment terms, and the obligations that come with each option.
How Do Solar Loans, Leases, PPAs, and PACE Differ?
A solar loan or PACE assessment lets you own the system. A lease or PPA leaves ownership with a company. PACE also adds repayment to your property tax bill and can create a lien with priority over your mortgage. Those differences can affect your monthly budget, maintenance responsibilities, and plans to sell the house.
Question | Solar loan | Lease | PPA | PACE
|
Who owns it | You | Company | Company | You |
What you pay | Loan payments (lender sets APR and fees) | Fixed monthly payment; some leases rise each year | Price per unit of power the system produces | Assessment added to your property tax bill |
Payments can rise? | Can re-amortize if a required paydown isn't made (CFPB) | "Under some leases, your monthly payments go up over time" (Treasury) | Check "whether payments go up during the contract term" (Treasury) | Set by the assessment contract; check terms |
Lien or priority | Depends on loan type | Check contract | Check contract | "Takes priority over your mortgage" (Treasury) |
End of term | You own it once paid | May buy at "fair market value"; you don't automatically own it (Treasury) | You don't automatically own it (Treasury) | You own it |
Who maintains | You (warranties may help) | Usually the company (Treasury) | Company | You |
Read the contract instead of relying on the monthly payment shown in a sales presentation. A lease may include yearly increases. A PPA ties charges to the electricity the system produces. A loan may require a large principal payment to avoid a later increase in monthly payments. PACE deserves extra attention because unpaid assessments can put the property at risk.
What Is a Prepaid Lease?
A prepaid lease lets you pay much of the lease cost upfront, sometimes using a third-party lender. The company still owns the equipment during the lease. Paying upfront doesn't turn the arrangement into a purchase or give you the system owner's tax benefits. Participate Energy, for example, describes a prepaid lease with a 25-year initial term and an option to buy the system at fair market value after the initial six-year period. Its terms also describe transfer provisions for a home sale. These details are specific to that provider, so read the current contract before deciding whether the arrangement fits your plans.
Solar PPA vs Lease in One Line Each
With a lease, you generally pay to use the solar equipment, often through a set monthly amount. With a PPA, you pay for the electricity the system produces, usually at a contracted price per kilowatt-hour. Your bill can change with production. Neither option automatically gives you ownership at the end of the contract. Compare the full payment schedule, maintenance terms, transfer rules, and any purchase option before signing. The trade-offs of leasing versus buying can help you prepare questions for each provider.
What Should a Separate Home Backup Budget Include?
Start by listing the battery, any extra batteries, the transfer panel, electrician labor, and permit fees separately. Keep these costs outside your solar financing contract. This makes it easier to see what backup power will cost and decide which equipment you actually need.
Budget for these items
Get a separate quote for each part of your backup setup. Your needs will depend on which devices you want to run and how long you need them to stay on.
Battery unit: Choose one that can handle the essential circuits you want to keep running.
Extra battery packs: Add these only if your runtime estimate shows you need more capacity.
Transfer or smart panel: Include a compatible panel if you want backup power for selected household circuits.
Electrician and permit: Get a written quote from a licensed electrician for installation and any required local permits.
Solar panels (optional): Include them separately if you plan to connect panels to the battery's solar input.
Estimate your backup runtime
A battery's listed capacity isn't all available to power your devices. For planning, use 5,017.6Wh of capacity and allow 15% for conversion losses. That leaves about 4,265Wh of usable energy. If your selected 120V circuits use an average of 250W, the estimate is: 4,265Wh ÷ 250W = about 17 hours. This is only a planning estimate. Actual runtime depends on which devices are running and how much power they draw.
Consider the EcoFlow TITAN 5000 Classic
If your main goal is to keep essential 120V devices running during an outage, the EcoFlow TITAN 5000 Classic is one option to consider. It has a 5,017.6Wh base capacity and can expand to 30kWh with additional batteries. Treat it as a separate purchase, with its own equipment and installation costs. The EcoFlow TITAN 5000 Classic can provide 120V power through its built-in outlets. For backup power to selected household circuits, it works with the compatible 120V EcoFlow Smart Home Panel 10, installed by a licensed electrician. Solar panels can also be connected to its solar input if you choose to add them later.
EcoFlow TITAN 5000 Classic for essential backup
The EcoFlow TITAN 5000 Classic is designed for homes that need backup power for selected 120V essentials, such as a refrigerator, lights, router, or compatible medical devices. For medical devices, follow the device manufacturer's backup-power requirements and verify operation during switchover before relying on this setup. It works with the EcoFlow Smart Home Panel 10 (120V version), which a licensed electrician must install for circuit backup. You don't need solar panels to use a home battery. Many households start by running a home battery without solar, charging it from the grid and adding solar panels later if needed. With backup costs set aside, you can compare solar financing options by looking at their total cost over the full contract term.
How Do You Compare the Overall Cost of Each Option?
Add up every payment over the full contract term, including fees and annual increases. Then compare that total with the cash price and check what you'll own at the end. A low advertised monthly payment can still lead to a much higher total cost.
Solar loans: check the fees and payment changes
Some solar loans add dealer fees to the amount you borrow. The Consumer Financial Protection Bureau (CFPB) has reported that these fees can increase the principal substantially, even when the advertised interest rate looks low. Consider this illustrative example. It uses a $10,000 cash price, a 7% annual interest rate, and a 15-year term. These figures are examples, not current market offers.
Scenario | Principal | Monthly payment | Total paid over 15 years
|
No fee added | $10,000 | About $89.88 | About $16,179 |
30% fee added to principal | $13,000 | About $116.85 | About $21,033 |
In this example, adding $3,000 to the principal increases the total paid by about $4,850 over the loan term. Ask the lender to show the cash price, dealer fees, APR, and total repayment amount on paper. Also ask whether the loan can be re-amortized. Some solar loans were structured around a large principal paydown, often expected to come from the old 30% tax credit. Under certain contracts, monthly payments can increase around the 19th month if the borrower doesn't make that payment. Since a new 2026 installation doesn't qualify for the homeowner credit, make sure you can afford the payment schedule without it.
Leases and PPAs: look for annual increases
A starting payment doesn't tell you what you'll pay over 20 or 25 years. Check the annual increase, often called an escalator, and compare the total across the contract term. Here's an illustrative lease-style payment starting at $100 per month over 25 years:
Yearly increase | Payment in year 25 | Total over 25 years
|
0% | $100.00 | $30,000 |
2% | About $160.84 | About $38,436 |
3.5% | About $228.33 | About $46,740 |
These are examples, not quotes. If your starting payment is $150 instead of $100, multiply the figures by 1.5. For a PPA, calculate the cost using the contracted price per kilowatt-hour and the system's expected production each year. Ask how the provider handles lower-than-expected output and what happens if you sell your home.
PACE: understand the lien before signing
PACE financing lets homeowners repay qualifying improvements through a property tax assessment. That can make the payment structure look different from a regular loan, but the assessment can carry serious consequences. The U.S. Treasury warns that a PACE lien can take priority over a mortgage. Some mortgage agreements prohibit this type of financing, and failure to pay can lead to default or foreclosure. Before signing, total the assessment payments over the full term and ask your mortgage lender whether the arrangement is allowed.
What Protections Apply to Solar Loans, Leases, and PACE?
California homeowners have protections that can help them slow down a sales pitch and check the terms. PACE financing has specific federal and state requirements, while California solar contracts include disclosure and cancellation rules. Read the documents before work starts or money changes hands.
Protection | What it requires | Status and date | Source |
CFPB PACE rule (Regulation Z) | Applies Truth in Lending ability-to-repay rules and Loan Estimate/Closing Disclosure requirements to PACE; PACE isn't a qualified mortgage | Final rule published Jan. 10, 2025; effective March 1, 2026 | |
California PACE ability-to-pay | Program administrator can't approve funding without first determining the owner can pay | Operative April 1, 2018 (SB 242 / AB 1284) | |
California PACE confirm-terms call | Administrator orally confirms key terms in the owner's preferred language, subject to statutory provisions | Operative Jan. 1, 2018 | |
PACE work start | Contractor can't begin before the three-day right to cancel expires (with listed exceptions) | Operative Jan. 1, 2018 | |
PACE pricing | Contractor can't charge more for PACE than for cash | Operative Jan. 1, 2018 | |
PACE administrator licensing | Licensed and examined by DFPI | Operative Jan. 1, 2019 | |
California solar contracts | Solar Energy System Disclosure Document; generally at least three business days to cancel, or five if 65 or older. Different rules may apply to contracts negotiated at the company’s place of business. | Current CPUC guide |
Before signing, watch for large upfront deposits, excessive fees, promotional rates that hide later payment increases, or lenders that don't make a meaningful effort to check affordability. Ask for every promise in writing. Keep copies of the contract, disclosures, and payment schedule. If you suspect a contractor violated the rules, contact the California Contractors State License Board at 800-321-CSLB. For financial misconduct, you can file a complaint with the DFPI. Reviewing the common ways to finance solar side by side can also help you spot fees, escalators, and ownership terms that deserve a closer look.
Conclusion
In 2026, no financing option restores the expired federal solar tax credit for new installations. Before signing, compare the total cost, including loan fees, payment increases, lease or PPA escalators, and PACE lien terms. Check ownership, maintenance responsibilities, and what happens if you sell your home. Read every contract carefully and get unclear terms explained in writing. If you also need outage backup, keep that expense separate from your solar financing. The EcoFlow TITAN 5000 Classic may suit homes that need backup for selected 120V essentials. Request written equipment and installation quotes before making a decision.
FAQs
Can I get the solar tax credit if I lease my panels?
No. The leasing company owns the solar equipment, so any available system-owner tax credit belongs to the company, not you. You can't claim the credit simply because the panels are installed on your home. The federal homeowner credit also ended for systems placed in service after December 31, 2025.
What's the difference between a solar PPA and a lease?
A solar lease usually charges a fixed monthly amount to use the equipment. A power purchase agreement (PPA) charges you for the electricity the system produces, based on a contracted price per kilowatt-hour. With either option, the company owns the system, so check payment terms and contract conditions before signing.
Is PACE financing a tax credit?
No. Property Assessed Clean Energy (PACE) is a financing option that lets you repay eligible improvements through your property tax bill. You own the solar system, but the financing creates a property assessment that can take priority over your mortgage. Ask your mortgage lender about restrictions and review the full repayment terms before agreeing to PACE financing.
Why did some solar loan payments jump after 18 months?
Some loans were structured to re-amortize around the 19th month unless the borrower made a large principal payment. The expected payment was often tied to the former 30% homeowner tax credit. Read the loan terms carefully, especially if you're financing a system installed in 2026.
Is a prepaid solar lease the same as buying?
No. You pay upfront, but the leasing company still owns the system. Some contracts offer a later purchase option at fair market value, so check the timing, price terms, and transfer rules before signing.
