By Solar loan vs solar lease comparison: the ultimate 2025 guide for homeowners
Solar loan vs solar lease comparison is one of the most important questions homeowners face when deciding how to finance a solar system. At first glance, both options look similar: you get solar panels, you pay a monthly bill, and you save on electricity. But over 25–30 years, the differences can mean tens of thousands of dollars, easier or harder home sales, and very different levels of control. This guide is written like a mini-book, so you have everything you need in one place to make an informed decision.

Introduction: Why Financing Matters
When most people think of solar, they imagine the panels on the roof and the lower electric bill. But the way you pay for those panels is just as important as the technology itself. A solar system is not just an appliance; it’s a 25- to 35-year investment. The financing method you choose—loan or lease—shapes how much you save, who gets the incentives, and whether you build equity in your system or simply rent the benefits.
In 2025, solar has become mainstream. Millions of homes already have panels, and utilities continue to raise rates. The question is no longer “Should I go solar?” but “How should I pay for it?” For many families, the choice between a loan and a lease is the biggest financial decision they’ll make about their home energy future.
This guide goes beyond simple pros and cons. We’ll explore real examples from different states, explain tax credits in plain language, describe what happens if banks or companies change, and even share how homebuyers react when they see solar panels on a house for sale. By the end, you’ll know which option fits your lifestyle, your finances, and your long-term plans.
Chapter 1: What Is a Solar Loan?
A solar loan is much like a car loan or mortgage. A bank, credit union, or specialized solar finance company provides money for your installation, and you repay it in fixed monthly installments. Terms usually range from 10 to 30 years. Interest rates vary, but many are competitive with home improvement loans. The key is that you own the solar system when you finance it with a loan.
There are two main types of solar loans:
- Secured loans: These are attached to your property, similar to a second mortgage or PACE program. They often have lower rates but may complicate resale or refinancing.
- Unsecured loans: These are based on your credit score and do not use your home as collateral. Interest may be slightly higher, but they are simpler when moving.
Solar loans have some unique features compared to car loans or mortgages. Many have no prepayment penalties, meaning you can pay off the balance early. Some offer interest-only periods while you wait for your tax credit refund, so you’re not burdened with full payments right away. Others allow the loan to be structured to match your utility savings, making the transition smooth.
Here’s a simple case study:
Case study: Maria in Florida
Maria financed a $25,000 solar system with a 25-year loan at $150 per month. Thanks to the 30% federal tax credit, she received $7,500 back at tax time, which she applied toward the loan balance. Her monthly payments roughly matched her old electric bill. After 25 years, her panels will still produce power for another decade, giving her thousands of dollars in nearly free electricity. Best of all, she owns the system outright, and if she sells her home, buyers see the panels as a valuable upgrade.
Advantages of solar loans:
- You keep ownership of the system.
- You qualify for all incentives (federal, state, local).
- You build long-term equity—your payments end, but your panels keep producing.
- You have freedom to choose maintenance providers and upgrade your system.
Disadvantages of solar loans:
- You must qualify based on credit or income.
- You are responsible for maintenance (though warranties often cover major parts).
- Loan payments count toward debt-to-income ratio if you refinance your mortgage.
Chapter 2: What Is a Solar Lease or PPA?
A solar lease, often structured as a Power Purchase Agreement (PPA), is fundamentally different. With a lease, the company owns the panels. You simply pay them for the right to use the energy those panels produce. Lease terms typically last 20 to 25 years. At the end, you may be able to renew, buy the system, or have it removed.
Leases usually come in two forms:
- Fixed monthly lease: You pay a flat fee regardless of how much energy the panels produce.
- PPA (Power Purchase Agreement): You pay per kilowatt-hour (kWh) at a set rate, often lower than your utility price.
Most leases include an annual escalator of 1–3%. That means your payment increases each year. Over two decades, this can add up to thousands of extra dollars. Many homeowners sign leases without realizing how much their payments will grow in year 15 or 20.
On the positive side, leases usually require little or no upfront cost. Approval is easier than for a loan, since the company owns the system. Maintenance, repairs, and monitoring are handled by the provider. If the inverter fails in year 12, you don’t pay for it—the company does. Some leases even guarantee performance, promising to pay you back if the system underproduces.
Case study: David in California
David signed a 25-year lease with no money down. His monthly payment was $140, slightly less than his old electric bill. He liked the fact that maintenance was included, and he didn’t need to worry about repairs. However, after 12 years, when he decided to sell his home, buyers were hesitant to assume the lease. He ended up having to buy out the contract at closing, which reduced his profit on the sale.
Advantages of solar leases:
- $0 down or very low upfront cost.
- Lower credit requirements for approval.
- Maintenance, monitoring, and repairs are included.
- Performance guarantees provide predictability.
Disadvantages of solar leases:
- You never own the system.
- You don’t qualify for tax credits or incentives.
- Payments often escalate each year.
- Resale of your home can be complicated by the lease contract.
Chapter 3: Ownership and Incentives
Ownership is the single biggest financial difference between loans and leases. With a loan, you own the panels and can claim incentives. With a lease, the company owns the panels and takes the incentives for itself. The biggest incentive in 2025 is the 30% federal solar tax credit (ITC), but many states offer additional rebates or credits.
Example: Florida homeowner
A $25,000 system earns a $7,500 federal credit. Net cost = $17,500. Over 25 years, that difference alone can save more than $10,000 compared to a lease. Florida doesn’t offer additional state credits, but homeowners still benefit from the ITC and net metering.
Example: New York homeowner
A $25,000 system earns a $7,500 federal credit plus a 25% state credit up to $5,000. Total benefit = $12,500. Net cost = $12,500. The lease customer in New York pays full price while the lender company pockets the credits.
Example: California homeowner
A $25,000 system earns a $7,500 federal credit plus possible utility rebates. Net cost may be $17,000 or less. In high-rate states like California, the long-term benefit of ownership is even greater.
In every state, ownership means you—not the company—benefit from incentives. This alone often makes loans more attractive for long-term savings.
Chapter 4: Risks, Stability, and Bankruptcy
Loans and leases also carry different risks. With a loan, your risk is mostly personal: you must make payments, and you are responsible for upkeep. With a lease, your risk is tied to the company that owns your system.
Loan risk: If your bank sells your loan, your payment simply transfers to a new servicer. If the bank goes bankrupt, your loan remains valid and is taken over by another institution. Your ownership is never in question.
Lease risk: If your leasing company is sold or goes bankrupt, your contract is considered an asset and is sold to someone else. Payments continue, but service may change. Some homeowners have reported poor support and long waits for maintenance after lease transfers.
Case study: Sungevity bankruptcy
In 2017, Sungevity, a major solar leasing company, filed for bankruptcy. Contracts were sold to investors. Customers still had to pay, but many reported delays and poor communication. This illustrates the danger of depending on a company for 25 years.
Chapter 5: Selling Your Home & Buyer Psychology
One of the most important moments in solar financing is when you sell your home. Buyers react very differently to loans and leases.
Loan: Owned solar is seen as a home upgrade. According to Zillow research, homes with owned solar sell for about 4% more. Buyers appreciate lower bills and like that the system is already paid for. If they don’t want to assume the loan, you can pay it off at closing. The system remains with the home as an asset.
Lease: Leased solar is often a red flag. Buyers must agree to assume the lease. Some do, but many don’t. Real estate agents often report buyers walking away rather than signing a 20-year contract. If the buyer refuses, you may have to buy out the contract or remove the system, both of which cost money.
Buyer psychology matters. Imagine two homes side by side: one with owned solar, one with leased solar. Most buyers choose the owned system, even if the panels look identical, because the financial difference is huge.
Chapter 6: Roof Replacements, Maintenance & End of Contract
Your roof will eventually need repair or replacement. Here’s how it works under each option:
Loan: Since you own the system, you choose the contractor for removal and reinstall. You can shop around, compare bids, and even upgrade during the process. Companies like RemovalReinstall.com specialize in this work. You’re in control.
Lease: You must go through the leasing company’s approved vendors. This means you follow their schedule and pay their prices. If the company is slow or expensive, you have little choice. Many homeowners report delays when roof work becomes urgent.
End of contract: After 25–30 years, the paths diverge. With a loan, you own a system still producing 80–85% of its original power. With a lease, you may be offered renewal, buyout, or removal. After decades of payments, you end up without an owned asset.
Chapter 7: Financial Comparisons & Lifetime Scenarios
Let’s run some lifetime numbers on a $25,000 system.
Loan: Federal tax credit = $7,500. Net cost = $17,500. Monthly loan ~$150. Over 25 years, total cost ~$45,000, but at the end you own the system, and it keeps producing for 5–10 more years at almost no cost. Lifetime benefit = savings of $20,000–$30,000 compared to utility bills.
Lease: $150/month for 25 years = $45,000. No ownership. No tax credits. No savings after contract ends. Lifetime benefit = lower than a loan customer, despite paying the same monthly amount.
In plain terms, loans and leases may start equal, but ownership always wins over time.
Chapter 8: Extended FAQ Library
Can I switch from a lease to a loan?
Not directly. You must buy out your lease, then finance it. This is usually expensive and rarely worth it.
What if I move in year 8?
Loan: you can pay off or transfer the loan. Lease: the buyer must assume the contract, which can scare buyers.
Can I refinance my mortgage with solar?
Yes. With a loan, solar is an improvement and often increases appraisal value. With a lease, lenders may require extra paperwork, which can slow the process.
What happens if I default?
Loan: the bank can place a lien or repossess. Lease: the company can terminate the contract and demand penalties.
Do solar panels increase property taxes?
In most states, no. Solar is tax-exempt even if it increases value. Check your local laws.
Which is better for businesses?
Loans, because businesses can claim tax credits and depreciation. Leases don’t allow this.
Do leases have performance guarantees?
Yes, many leases guarantee a certain amount of energy production. If the system underperforms, the
