TL:DR: The core difference in solar lease vs PPA vs loan is ownership. With a lease or PPA, a third party owns the panels. With a loan, the homeowner owns them. Leases charge a fixed monthly fee. PPAs charge per kilowatt-hour. Loans build equity but carry debt. Each structure changes costs, tax benefits, home sales, and exit options differently.
What Is the Difference Between a Solar Lease, a PPA, and a Solar Loan?
The three agreements differ in who owns the system and what the homeowner pays for. The ownership question controls almost everything else: tax credits, maintenance, home sales, and how hard the agreement is to exit.
How a Solar Lease Works
A solar lease is an agreement to pay a monthly fee for a provider-owned solar system. The payment stays the same whether the panels produce a lot or a little. Most leases run 20 to 25 years. At the end, the homeowner may renew, remove the system, or buy it at fair market value.
How a Solar PPA Works
A solar power purchase agreement is a contract where the homeowner buys the electricity the panels produce. The provider owns the system and bills a set kilowatt-hour rate. The monthly bill rises and falls with production. The homeowner does not automatically own the system when the PPA ends.
How a Solar Loan Works
A solar loan is financing that lets the homeowner buy the system and repay the lender over time. The homeowner owns the panels from day one. Ownership brings homeowner equity, but it also brings repair costs after warranties expire. Loan terms commonly run 10 to 25 years.
How Do the Three Agreements Compare Side by Side?
A side-by-side solar lease vs PPA vs loan comparison shows one pattern. The table below shows how ownership shifts cost, risk, and flexibility between the homeowner and the provider. Read it as a starting point, because individual contracts vary widely.
| Factor | Solar Lease | Solar PPA | Solar Loan |
| Who owns the panels | Provider | Provider | Homeowner |
| What you pay for | Use of the equipment | Electricity produced | The system itself, plus interest |
| Payment type | Fixed monthly amount | Per kilowatt-hour | Fixed loan payment |
| Payment increases | Possible annual escalator | Possible annual escalator | Usually none, unless re-amortized |
| Who handles repairs | Provider, per contract | Provider, per contract | Homeowner after warranties |
| Low production risk | Homeowner still pays full fee | Bill drops with output | Homeowner still pays loan |
| Selling the home | Transfer or buyout | Transfer or buyout | Payoff or assumption |
| Typical lien or filing | UCC-1 by provider | UCC-1 by provider | Often a UCC-1 by lender |
The production row matters more than most homeowners expect. A PPA customer pays less when panels underperform. A lease customer usually relies on a performance guarantee for any credit. A loan customer carries the full production risk.
How Did the 2026 Tax Credit Change Affect Each Option?
The homeowner solar tax credit ended for systems placed in service after December 31, 2025. The One Big Beautiful Bill Act, signed July 4, 2025, terminated the Section 25D Residential Clean Energy Credit. That change reshaped the solar tax credit picture for 2026 and the solar lease vs. PPA vs. loan math.
For loans, a new system no longer earns the homeowner a federal credit. This matters because many solar loans were built around a 30% credit the homeowner was expected to receive.
For leases and PPAs, the provider may still claim the Section 48E business credit on qualifying systems. That credit generally applies to third-party-owned solar placed in service through 2027, subject to construction-start rules. The provider decides how much of that value, if any, reaches the homeowner’s pricing.
Homeowners who installed in 2025 or earlier should check the Permission to Operate date. That utility approval date often shows whether the system was placed in service in time for the credit.
What Hidden Costs Should You Check in Each Contract?
The most expensive terms usually sit in clauses sales presentations skip. Each agreement type has its own cost trap. The guidance from the Treasury’s solar awareness page recommends confirming payment increases, extra fees, and performance guarantees before signing.
Escalator Clauses in Leases and PPAs
A solar lease escalator raises the payment or kilowatt-hour rate by a fixed percentage every year. Small percentages compound over decades. A 2.9% annual escalator nearly doubles the payment by year 25. A $120 first-year payment would reach about $238 by the final year.
Utility rates may or may not rise at the same pace. If utility rates grow slower than the escalator, projected savings can shrink or disappear.
Dealer Fees and Prepayment Traps in Solar Loans
A solar loan dealer fee is a markup added to the loan principal above the system’s cash price. The CFPB solar financing report found these fees can raise loan principal by 30% or more. Lenders often do not label the fee as a markup.
Many solar loans also expect a large prepayment within the first year or two. That prepayment was often meant to come from the tax credit. If the homeowner skips it, the lender may recalculate the loan and raise the monthly payment.
Performance Guarantees and Production Shortfalls
A performance guarantee promises that the system will produce a minimum amount of electricity. The contract controls how shortfalls are measured and paid. Some guarantees pay a credit once a year. Others require the homeowner to file a claim.
What Happens When You Sell Your Home With Each Agreement?
Selling a house with solar usually requires a transfer, a buyout, or a payoff before closing. The exact path depends on the agreement type and the provider’s approval process.
- Lease or PPA transfer: The buyer signs an assumption agreement and takes over payments. Most providers require the buyer to pass a credit check.
- Solar lease buyout: The seller pays the provider a contract-defined amount to purchase the system. The system then transfers with the house.
- Loan payoff: The seller pays the remaining balance, often from sale proceeds at closing.
- Moving the system: Some contracts allow relocation, but removal and reinstallation costs usually fall on the homeowner.
A UCC-1 fixture filing often appears on the title search. A UCC-1 fixture filing is a public notice that a provider or lender claims an interest in the equipment. It does not always block a sale. However, the title company, such as Tesla, may require it to be released or explained before closing.
Timing creates the most common problem. Provider transfer approvals can take weeks. Requesting the transfer at listing, not after an offer, reduces the risk of a delayed closing.
What Are Your Options If a Solar Agreement Is Not Working?
Options depend on the agreement type, the signing date, state law, and how the contract was sold. No single path fits every homeowner, and none is guaranteed.
| Situation | Lease or PPA | Loan |
| Still within the cancellation window | Written cancellation may be possible | Written cancellation may be possible |
| Payments exceed savings | Buyout or negotiated change | Refinance or payoff |
| System not producing | Performance guarantee claim | Warranty claim with installer |
| Misleading sales claims | Complaint and contract review | Complaint and lender dispute |
| Provider or installer bankruptcy | Payments usually continue to a successor | Loan usually remains owed |
The FTC Cooling-Off Rule may apply to some sales made at the home. It generally allows three business days to cancel. Some states add longer windows. Texas, for example, gives five business days for many residential solar contracts signed on or after June 20, 2025.
Bankruptcy rarely ends an agreement automatically. When Sunnova filed for bankruptcy in June 2025, customers still owed payments while some systems went unrepaired. Loan obligations usually survive an installer’s failure because the lender, not the installer, holds the debt.
What Documents Should You Gather Before Reviewing Your Agreement?
A useful contract review starts with complete paperwork. Missing pages often hide the clauses that decide the outcome.
- The signed agreement: Include every page, addendum, and change order.
- The sales proposal: Keep the savings estimate and any tax credit claims.
- Loan disclosures: Look for the cash price, the amount financed, and the prepayment schedule.
- Utility bills: Gather at least 12 months before and after installation.
- Production data: Download monitoring reports from the system’s app or portal.
- Utility approval letter: Note the Permission to Operate date.
- Written communications: Save emails, texts, and complaint records with the provider.
Comparing the sales proposal against actual bills often reveals the gap between promised and real savings. That gap can matter in a dispute over misleading sales claims.
Which Option Fits Which Homeowner?
The right choice depends on tax situation, plans to move, cash on hand, and tolerance for repair risk. Comparing solar lease vs PPA vs loan on these factors is more useful than comparing monthly payments alone.
- A loan may fit: Owners who plan to stay, want equity, and can verify the cash price against the principal.
- A lease may fit: Homeowners who want predictable payments and provider-handled maintenance, with a low or zero escalator.
- A PPA may fit: Homeowners who want to pay only for actual production and accept a variable monthly bill.
Net metering rules also shape the answer. A utility that credits exported power at a low rate reduces savings under every agreement type.

Frequently Asked Questions About Solar Lease vs PPA vs Loan
Is a solar lease or a PPA better?
Neither is better for every homeowner. A lease offers a predictable monthly fee. A PPA charges only for electricity produced, so bills drop when production drops. The escalator rate and performance guarantee often decide which agreement costs less.
Can I still get the federal solar tax credit with a loan in 2026?
Generally, no, for systems placed in service after December 31, 2025. The homeowner credit under Section 25D ended then. Systems placed in service earlier may still qualify. A tax professional can confirm eligibility.
Does a solar lease hurt home resale value?
A solar lease can complicate a sale because the buyer must qualify and accept the payments. A high escalator or a large remaining balance can discourage buyers. Starting the transfer process early reduces delays at closing.
What is third-party-owned solar?
Third-party-owned solar is a system owned by a company rather than the homeowner. Solar leases and PPAs are the two main forms. The company typically claims available tax credits and handles maintenance under the contract.
Can I get out of a solar contract after the cancellation window closes?
It may be possible, but it is not guaranteed. Common paths include a buyout, a sale transfer, a refinance, or a dispute over misleading sales practices. The outcome depends on the contract terms, state law, and the documented facts.
