Solar lease vs solar loan: what's the difference?
A solar lease and a solar loan both help you use solar with less or no upfront cost—but the ownership and contract rules are different. Here’s what to expect so you can compare offers safely.
Quick answer: who pays for what?
A solar lease (or PPA) is usually a contract where you pay monthly for the energy the solar system produces. You typically don’t own the panels; the provider/owner does.
A solar loan is usually financing that helps you buy the system (or part of the system). You make payments to own the solar equipment over time. Terms and incentives can vary a lot by state and utility.
In both cases, the exact numbers depend on your home, roof, electric bill, local rates, and the contract. No two offers are the same.
Solar lease / PPA: how it usually works
With a solar lease or Power Purchase Agreement (PPA), a provider installs the solar system and you pay for its output—often as a set monthly payment or a per-kWh energy rate.
Because the provider typically owns the system, the federal tax credit is usually claimed by the provider, not you. That trade-off can mean lower upfront cost for you, but it can also mean you may not benefit the same way you would if you owned the system.
Some contracts include payment “escalators” (increases over time). Even a small annual increase can change your total cost over years. Always check: the term length, the monthly payment schedule, and what happens if you move or your roof needs repairs.
Solar loan: how it usually works
With a solar loan, you generally pay down the system cost over time. Many homeowners may finance through a lender or through a provider-arranged program.
If you own the system, you may be in a different position than lease/PPA customers. For example, ownership usually affects who may claim certain incentives. The federal tax credit rules can be complex, and what applies to you depends on how the deal is structured.
A solar loan can offer more control, because you’re typically responsible for ownership-related decisions and maintenance responsibilities vary by contract. You also want to confirm whether the loan has early payoff terms, interest details, and whether there are any fees if you sell your home.
Key differences to compare (before you choose)
When people compare lease vs loan, they often focus on the monthly number first. But the better comparison is the full contract picture.
Here are smart items to look for:
- Who owns the system? (Lease/PPA: usually the provider. Loan: usually you.)
- Who gets incentives? (Often the provider on leases/PPAs, but confirm for your exact contract.)
- Payment increases: Any escalators on leases/PPAs or interest/fees on loans.
- Length of the agreement: Many leases/PPA terms are long (often 15–25+ years). Loans are shorter (often 5–20+ years), but varies.
- Move/sale rules: What happens if you move, refinance, or sell? Transfer rights can be different.
- Maintenance and roof work: Who pays for what if equipment has issues or your roof needs repairs.

What SunWise Lease does (and what it doesn’t)
SunWise Lease is a free service that helps you get matched with vetted local solar providers. We’re not an installer, lessor, or financial advisor, and we don’t give financial advice.
Our goal is to help you understand common options (lease, PPA, and solar loan) and connect you with providers so you can compare offers in your area.
Solar savings and costs vary by home, utility, and state, so we encourage you to collect all numbers in writing and compare multiple quotes. If someone pressures you to sign on the spot, it’s okay to slow down—read the full contract first and ask questions. Some states regulate high-pressure door-to-door or phone sales.
How to decide what’s best for your situation
A lease/PPA can fit people who want lower or no upfront cost and prefer predictable payments—especially if they may not stay in the home for the long term. But you should still plan for possible payment increases and long contract durations.
A solar loan can fit people who want to own the system and potentially benefit more over time, but it often comes with higher upfront cost and you’ll want to understand the full financing terms.

A solar lease/PPA usually means you pay monthly for solar energy while the provider owns the panels, while a solar loan usually means you finance buying the system—compare ownership, incentives, payment increases, and move/sale terms to choose.
