Solar Lease vs Loan vs Cash Purchase: Which Is Right for You?

Solar financing generally comes down to three paths: pay cash, take out a loan, or use a lease/PPA. Each has a meaningfully different impact on your savings, ownership, and flexibility.

Cash purchase

You pay the full system cost upfront and own the system outright from day one.

Pros:

• Maximizes long-term savings — no interest or lease markup
• You directly claim the federal tax credit yourself
• Simplest to understand, with the fewest ongoing contractual obligations
• Adds straightforward value to your home if you sell

Cons:

• Requires the largest upfront capital
• Ties up funds that might otherwise be invested elsewhere

Solar loan

You borrow to cover the system cost and repay over time, but you own the system just as you would with a cash purchase.

Pros:

• You still own the system and claim the federal tax credit yourself
• No large upfront payment required
• Many loans are structured so monthly payments are comparable to or less than your prior utility bill

Cons:

• Interest costs reduce your net savings compared to cash
• Total cost over the loan term is higher than the cash price

See our financing options overview for more detail on typical loan structures.

Lease or PPA (power purchase agreement)

A third party owns the system installed on your roof; you pay either a fixed monthly lease payment or a per-kWh rate for the electricity it produces (PPA), typically with no upfront cost.

Pros:

• Little to no upfront cost
• The leasing company typically handles maintenance and monitoring
• Can still reduce your monthly electricity costs compared to your utility rate

Cons:

• You don’t own the system, so you can’t claim the federal tax credit — the leasing company does
• Total savings are generally lower than ownership over the system’s lifetime
• Can complicate a home sale, since the lease needs to transfer or be paid off
• Payments may include an annual escalator clause that increases the rate over time

Which one fits your situation?

• If you have the cash available and don’t need it for other priorities, a cash purchase generally maximizes your savings.
• If you want ownership benefits without a large upfront payment, a solar loan is often the middle-ground choice most homeowners land on.
• If you want the simplest possible entry with no upfront cost and don’t mind giving up the tax credit and some long-term savings, a lease or PPA may fit, though it’s worth reading the contract terms carefully — see our guide on questions to ask before signing.

Bottom line

There’s no universally “best” option — it depends on your available capital, how much you value long-term savings versus low upfront cost, and how long you plan to stay in your home. Cash and loan both preserve ownership and the tax credit, making them generally the stronger financial choice when available; lease/PPA trades some savings for zero upfront cost and less responsibility.
