Solar: Buy, Loan, Lease, or PPA, Which Is Best?
Going solar is a big decision, and how you pay for it matters almost as much as the equipment you choose. There are four main ways to finance a home solar system: buying with cash, using a solar loan, signing a lease, or entering a power purchase agreement (PPA). Each one changes who owns the panels, how much you pay upfront, who claims any tax benefits, and how much value you keep over 20 or more years. Here is a plain-English breakdown to help you compare.
The Four Ways to Pay for Solar
1. Cash Purchase
With a cash purchase, you pay the full cost of the system upfront and own it outright from day one. There are no monthly payments and no interest. You keep every dollar of energy savings and any export credits your utility offers. This option usually delivers the best long-term value because you avoid financing costs entirely. The downside is the large upfront expense, which is out of reach for many households.
2. Solar Loan
A solar loan lets you own the system while spreading the cost over time, similar to a car loan or home improvement loan. You still own the panels, so you keep the long-term value and any incentives available to owners. Monthly payments replace the upfront cost, but you will pay interest, and some solar loans carry fees built into the price. Once the loan is paid off, your remaining energy savings are yours to keep for the life of the system.
3. Solar Lease
With a lease, a solar company owns the equipment and installs it on your roof. You pay a fixed monthly amount to use the system, regardless of how much power it produces. You do not own the panels, so you do not qualify for tax credits or incentives that go to the owner. Leases require little or no money down, which appeals to homeowners who want lower upfront cost, but you give up long-term ownership value.
4. Power Purchase Agreement (PPA)
A PPA is similar to a lease, but instead of a fixed monthly fee, you pay for the electricity the system produces at a set rate per kilowatt-hour. The solar company owns and maintains the equipment. Your bill goes up or down with how much the panels generate. Like a lease, a PPA usually needs little upfront cash, but you do not own the system and cannot claim owner incentives yourself.
Who Claims the Tax Credit?
This is where 2026 rules matter. The 30% federal Residential Clean Energy Credit (Section 25D), which homeowners used to claim when they bought solar or batteries, ended after December 31, 2025. If you buy a system now with cash or a loan, that federal credit is no longer available to you.
However, businesses can still use the commercial clean energy investment credit (often called 48E). A solar company that owns the system through a lease or PPA may qualify for that commercial credit. In some cases, the provider passes part of those savings on to you through a lower monthly rate. This does not put money in your pocket directly, and it depends entirely on the company and the contract terms. Incentives change often, so confirm what applies in your state and always consult a qualified tax professional before assuming any benefit.
Comparing Long-Term Value
Ownership almost always wins on long-term value. When you buy with cash or a loan, the system becomes an asset, and studies have generally shown that owned solar can add to a home's value. Once a loan is paid off, your energy savings continue for years with only maintenance costs.
Leases and PPAs lower your barrier to entry but cap your upside. Because a third party owns the equipment, your savings are usually smaller, and the arrangement can complicate a future home sale. Many leases and PPAs include an annual price escalator, meaning your payment rises a set percentage each year. Over 20 years, that can add up.
Pros and Cons at a Glance
- Cash purchase: Best long-term value and full ownership, but the highest upfront cost.
- Solar loan: Ownership with no large upfront payment, but you pay interest and possible fees.
- Lease: Low upfront cost and predictable payment, but no ownership and no owner incentives.
- PPA: Low upfront cost and you pay only for power produced, but no ownership and payments can escalate.
Red Flags in Solar Contracts
Whatever route you choose, read the contract carefully. Watch for these warning signs:
- Steep annual escalators. A high yearly price increase on a lease or PPA can erase your savings over time.
- Vague savings promises. Be skeptical of guaranteed dollar amounts or "free solar" claims. Ask for the assumptions behind any estimate.
- Long or unclear terms. Some contracts run 20 to 25 years. Know your buyout, transfer, and end-of-term options before you sign.
- Liens and home-sale complications. Understand how a lease or PPA transfers to a buyer if you sell your home.
- Pressure tactics. A reputable installer gives you time to review. High-pressure, sign-today sales are a red flag.

Frequently asked questions
Buying with cash or a loan usually delivers more long-term value because you own the system and keep the savings. Leasing lowers your upfront cost but means a company owns the equipment, so you give up ownership value and owner incentives. Your best choice depends on your budget and goals.
The 30% federal Residential Clean Energy Credit (Section 25D) for homeowners ended after December 31, 2025, so it is no longer available for new purchases. A company that owns a leased or PPA system may qualify for the separate commercial credit and could pass some savings to you. Confirm with a tax professional.
With a lease, you pay a fixed monthly amount to use the system no matter how much power it makes. With a PPA, you pay a set rate for each kilowatt-hour the system actually produces, so your bill varies with output. In both, a third party owns the equipment.
Watch for steep annual price escalators, vague or guaranteed savings claims, very long terms, unclear buyout or home-sale transfer rules, and high-pressure sales tactics. Read the full contract and take time to review before signing.
