Solar Panels vs Solar Lease: Buying, Leasing, or PPA?

The solar industry has a quiet problem: a lot of homeowners who went solar don't fully understand the agreement they signed.

They know their electricity bill went down. But they're not sure if they own their panels, why they can't claim the federal tax credit, and what happens when they try to sell their house.

This article gives you the straight comparison between the three ways to go solar: buying outright (cash or loan), leasing the system, and entering a Power Purchase Agreement (PPA). By the end, you'll know exactly which structure makes financial sense for your situation.

The Three Structures at a Glance

Buying (cash or loan): You own the system. You claim the 30% Federal Investment Tax Credit. Your long-term savings are the greatest. You take on the upfront cost. Solar lease: A solar company owns the panels on your roof. You pay them a fixed monthly amount for using the system. No upfront cost. You do not get the ITC. Power Purchase Agreement (PPA): A solar company owns the panels. Instead of a fixed lease payment, you buy the electricity the panels produce at an agreed per-kWh rate, typically below your utility rate. No upfront cost. You do not get the ITC.

The structure you choose affects your savings, your tax benefits, your home's resale process, and your long-term flexibility. Let's go deeper on each.

Option 1: Buying Your Solar System

Cash Purchase

You pay the full cost of the system upfront. In 2026, a typical residential system runs $18,000 to $35,000 before incentives.

After applying the 30% Federal ITC, your net cost drops by nearly a third:

$25,000 system - $7,500 ITC = $17,500 effective cost
Plus any state rebates or credits on top of that

You own the system completely. Every kWh it produces belongs to you. Every dollar of electricity savings is your dollar. When the system reaches payback (typically 6 to 12 years in sun-rich states), every year after that is pure financial gain.

Best for: Homeowners with sufficient liquid capital who want the maximum long-term return and plan to stay in the home for 10 or more years.

Solar Loan

You own the system but finance it over time. Solar loans typically range from 5 to 25 years at interest rates from 3.99% to 8.99% depending on credit score, loan term, and lender.

The ITC still applies: you still receive the 30% federal credit in year one. Many homeowners use the ITC refund to make a lump-sum payment against the loan principal in year one, reducing the outstanding balance and monthly payment.

Net cash flow in year one: For many systems, the annual electricity savings roughly offset the annual loan payments, creating close to a neutral or slightly positive first-year cash position. The math improves as electricity rates increase. Best for: Homeowners who want ownership benefits (ITC, full savings, no third-party entanglement) but prefer to preserve capital or don't have $20,000 to $35,000 in cash. Watch out for: Dealer fees. Some solar loans include an origination fee paid by the installer to the lender, which is rolled into your loan balance. On a $25,000 loan with a 30% dealer fee, your actual loan balance is $32,500, not $25,000. Ask specifically: "What is the loan amount I will owe after the agreement is signed?" and compare it to the cash purchase price.

Option 2: Solar Lease

A solar company installs panels on your roof and you pay them a fixed monthly amount, typically for 20 to 25 years.

Your lease payment is usually set below your current electricity bill, creating immediate savings. Year-over-year, lease payments typically escalate 1% to 3% annually per the contract.

The ITC situation: Because the solar company owns the system, they claim the 30% Federal ITC, not you. The ITC is a significant portion of why they're willing to install at no upfront cost. They keep that $7,500 credit on a $25,000 system. The savings comparison:

System owner with cash purchase: keeps 100% of electricity savings
Lease customer: saves the difference between their old utility bill and their lease payment, typically 10% to 30% less than the utility rate

Over 25 years, the cumulative savings gap between owning and leasing a system is often $15,000 to $40,000 depending on system size and local electricity rates.

The home sale complication: When you sell your home with a leased solar system, the buyer must either:

1. Assume the remaining lease payments, or

2. You pay the solar company to buy out the lease

Lease buyout prices vary by contract and remaining term. Some leases allow purchase at fair market value after certain periods. Others have buyout formulas that result in $8,000 to $25,000 costs to exit early.

A real estate agent we spoke with noted: "In the past two years, I've seen about one in six solar lease agreements create friction in a home sale. Buyers are sometimes reluctant to assume a long-term payment obligation on a system they didn't choose."

Best for: Homeowners who want the environmental benefit and some electricity savings without any upfront cost, who have little or no federal tax liability (making the ITC less valuable to them), and who plan to sell before the lease complicates things.

Option 3: Power Purchase Agreement (PPA)

A PPA is similar to a lease in that the solar company owns the system. The difference: instead of paying a fixed monthly amount, you pay a per-kWh rate for the electricity the panels produce.

Typical PPA rates in 2026: 8 to 14 cents per kWh, compared to national average utility rates of 14 to 22 cents per kWh depending on your state.

The appeal: On day one, you're buying solar electricity at a discount versus your utility rate. As utility rates rise, that discount grows. The risk: PPA rates also escalate. Typical escalation clauses run 1% to 3% per year. If your utility rate increases faster than your PPA rate, you win. If the utility slows rate increases (unlikely historically, but possible), the deal becomes less favorable over time. The ITC situation: Same as a lease: the solar company keeps the 30% Federal ITC. Home sale implications: Same complexity as a lease. The PPA must either be transferred to the new buyer or bought out. Best for: Homeowners in states with high electricity rates who want immediate savings with zero upfront cost and don't have sufficient federal tax liability to benefit from the ITC directly.

The 30% Federal ITC: Why Ownership Changes Everything

The 30% Federal Investment Tax Credit is the most important financial element of this comparison, and it's the one that swings the math decisively toward ownership.

On a $25,000 system:

Owner (cash or loan): receives $7,500 in federal tax credits
Lease or PPA customer: receives $0

That $7,500 gap is not symbolic. It's a direct dollar-for-dollar reduction in your federal tax bill. Combined with state incentives that often require ownership as well, the total incentive difference between owning and leasing can reach $10,000 to $12,000 on a mid-sized system.

The lease and PPA companies keep those incentives because they own the asset. That's how they make their economics work.

For a homeowner with adequate federal tax liability (most homeowners who pay $5,000 or more in federal taxes per year), this gap is too large to ignore.

The Home Sale Reality: What Solar Appraisers Say

Owned solar panels add measurable value to a home. A Lawrence Berkeley National Laboratory study found that homes with owned solar systems sell for approximately $4 per watt installed, or about $15,000 more on average for a typical residential system.

For a home sale, an owned solar system is an asset listed on the property. The appraiser factors it into the valuation. Buyers value the electricity savings they'll inherit.

A leased system is a liability in the eyes of many buyers, specifically the ongoing payment obligation. Some buyers are enthusiastic about assuming a lease. Others see it as a complication and negotiate a price reduction accordingly, or make the buyout a condition of sale.

This does not mean leased systems kill home sales. In strong solar markets like California and Arizona, buyers are more familiar with lease assumptions. But it does mean the ownership structure affects your flexibility as a seller.

When a Lease or PPA Actually Makes Sense

Despite the ITC disadvantage, leases and PPAs have legitimate use cases:

You have minimal federal tax liability. If you're retired with a low income, have significant deductions, or otherwise owe very little in federal taxes, the 30% ITC has little or no value to you. The lease/PPA model captures the economic benefit and passes some of it to you through a lower electricity rate. Your credit score doesn't qualify you for a favorable solar loan. Solar loan rates below 6% typically require a credit score of 700+. If your credit score is significantly lower, the available loan rates may make ownership less financially attractive, potentially shifting the comparison toward a PPA. You're absolutely certain you'll sell within 5 years. In this scenario, you won't reach the payback period on a purchased system anyway. A zero-upfront PPA that reduces your electricity bill from day one might make more sense than a $15,000 to $20,000 cash outlay you'll never fully recoup. Just factor the potential home sale complexity into your decision. You want zero maintenance responsibility. With a lease or PPA, the system owner (the solar company) is responsible for maintenance and repairs. With owned systems, while equipment is under manufacturer warranty, you may deal with claim processes and wait times.

The Loan to Avoid: The Predatory PACE Loan

PACE (Property Assessed Clean Energy) loans attach to your property tax bill rather than your personal credit. They allow homeowners with lower credit scores to finance solar without a traditional loan.

PACE loans have a problematic history of high interest rates (6% to 10%+), high origination fees, and serious home sale complications. Because the assessment is attached to the property, it becomes a lien that must be resolved before most home sales can close.

Consumer protection agencies in California and Florida have flagged PACE loan abuses extensively. If an installer offers a PACE loan as your primary financing option, get a second opinion on alternative financing before signing.

Decision Guide: Which Option Is Right for You?

Choose cash purchase if:

You have $15,000 to $25,000 available (after ITC), plan to stay 10+ years, and want maximum lifetime return.

Choose a solar loan if:

You want ownership benefits (ITC, full savings) but prefer to preserve capital. Shop for rates under 6% and ask specifically about dealer fees.

Choose a lease or PPA if:

Your federal tax liability is low, your credit disqualifies you from favorable loan rates, or you genuinely want zero upfront cost and are comfortable with the 20 to 25-year agreement and its home-sale implications.

Consider none of the above and wait if:

Your roof needs replacement within 5 years, your home has significant shading that hasn't been properly analyzed, or you're planning to move within 3 years.

The Question Every Solar Salesperson Should Answer

Before signing any solar agreement, ask this question:

"Can you show me the total amount I'll pay over the full term of this agreement versus my projected utility costs over the same period, including all rate escalators in the contract?"

A reputable solar advisor will produce this 25-year financial model without hesitation. If someone is reluctant to show you this comparison or tries to redirect you to monthly savings only, that's a red flag.

The Bottom Line

The "no money down" appeal of leases and PPAs is real. For some homeowners, it's the right call. But for most homeowners with adequate tax liability and access to reasonable financing, purchasing your solar system, whether with cash or a good solar loan, produces meaningfully better long-term results.

The 30% Federal Investment Tax Credit changes the math significantly. Don't sign it away without understanding the trade-off.

The 30% Federal Investment Tax Credit is available for qualifying residential solar installations through 2032 as of this writing. Tax credit availability depends on individual tax circumstances. Consult a qualified tax professional before making decisions based on tax incentives. Solar savings projections depend on local utility rates, solar production, net metering terms, and agreement structure. This article is for informational purposes only.
