Solar Lease vs Buy: Comparing Leases, PPAs, Solar Loans and Cash

In the solar lease vs buy decision, paying cash usually saves the most, and a fairly priced loan comes next. Leases and power purchase agreements (PPAs) cost little up front but pass much of the benefit to the owner. Watch for dealer fees on solar loans and check how each option affects a future home sale.

There are four common ways to go solar: pay cash, take a loan, sign a lease or sign a PPA. The first two make you the owner. The second two let a company own the panels on your roof while you pay for their use or their power. Each suits a different kind of homeowner.

Solar payment options compared

Paying cash for solar

Paying cash gives you the lowest total cost. There is no interest, no financing fee and no monthly payment, so every dollar of bill savings goes toward paying back your investment. You also own the system outright, which tends to make a home sale simpler.

The drawback is obvious: a large upfront outlay and the opportunity cost of tying up savings. Before draining an emergency fund, make sure you would still have a cushion if something else went wrong.

Some homeowners use home equity instead of savings. If that is your plan, compare the rates, fees and risks in our guide to a cash-out refinance vs. a HELOC. Both use your home as collateral, so missing payments can put the house at risk.

Solar loans and dealer fees

A solar loan lets you own the system without paying up front. You get the ownership benefits, including any state or local incentives, but you pay interest and often fees.

The biggest hidden cost is the dealer fee. Some lenders offer very low advertised rates by charging the installer a fee, which the installer typically adds to the system price. The fee can add a significant percentage to the amount you borrow.

Questions to ask any solar lender:

• What is the cash price, and what is the financed price?
• What is the APR, not just the interest rate?
• Is there a dealer fee, and how much is it?
• Is there a scheduled payment increase if I do not make a lump-sum paydown?
• Is the loan secured by a lien on my home or a fixture filing on the equipment?

Solar leases and power purchase agreements

With a lease or PPA, a company installs and owns the system. You pay either a fixed monthly lease payment or a per-kilowatt-hour rate under a PPA. The provider typically handles monitoring, maintenance and repairs.

These deals appeal to homeowners who want lower bills with little or no upfront cost and no maintenance responsibility. Because the company owns the system, it, not you, claims any tax benefits available to system owners. Federal tax rules for business-owned solar changed differently from the homeowner credit, so third-party-owned offers may be priced differently from owned systems in 2026; ask the provider to show exactly what the price assumes.

Watch the escalator

Many leases and PPAs include an escalator that raises your payment or per-kWh rate every year, often by a set percentage. If your utility's rates rise more slowly than the escalator, your savings can shrink or disappear over a 20- to 25-year contract.

How solar financing affects selling your home

Owned systems paid in full usually transfer with the house like any other fixture. Other arrangements add steps:

• Leases and PPAs: The buyer typically must qualify for and agree to take over the contract. If they will not, you may need to buy it out or, if allowed, pay for removal.
• Solar loans: Depending on how the loan is secured, you may need to pay it off at closing or clear a fixture filing before the sale can complete.
• Appraisals: Owned systems may add value in some markets. Leased systems generally do not count toward the home's appraised value, since you do not own them.

Solar also has insurance implications. Owned panels are generally treated as part of the home, so check your dwelling limit, as explained in how much dwelling coverage you need.

Which solar payment option is right for you?

• Choose cash if you have savings beyond your emergency fund and plan to stay long enough to reach payback.
• Choose a loan if you want ownership without the upfront outlay and can find financing without a large dealer fee.
• Consider a lease or PPA if you want modest savings with no upfront cost and no maintenance, and you have read the escalator and transfer terms carefully.

Start by estimating whether solar is worth it for your home at all, then compare quotes using price per watt before layering in financing.

The bottom line

Buying solar with cash or a fairly priced loan generally delivers the most savings, while leases and PPAs trade savings for convenience. Always compare the cash price with the financed price to expose dealer fees, and read escalator and transfer terms before signing. Recheck any offer built around the 30% federal homeowner credit, which no longer applies to 2026 installs.
