We compare ownership, total cost, fees, service responsibilities, home-sale terms, and 2026 tax rules so the payment fits the plan.
The equipment may look similar on the roof. The financial obligation can be completely different.
Pay the project price upfront and avoid solar-loan interest or lease payments.
Finance a homeowner-owned system through scheduled principal and interest payments.
A third party owns the equipment while you make payments under a long-term agreement.
Exact programs vary. Your written proposal and finance agreement control.
| Decision point | Cash | Loan | Lease |
|---|---|---|---|
| System owner | Homeowner | Homeowner, subject to lender terms | Third-party provider |
| Upfront cost | Highest | Often low or $0 down | Often low or $0 down |
| Ongoing solar payment | None | Principal and interest for the loan term | Monthly or prepaid lease obligation |
| Total-cost drivers | Project price and opportunity cost | Cash price, fees, APR, term, and prepayment | Payment, escalator, term, buyout, and end-of-term terms |
| Maintenance | Homeowner relies on written installer and manufacturer coverage | Same ownership responsibility as cash unless added coverage applies | Provider responsibility as defined by the lease |
| Home sale | Usually transfers with the home | Loan payoff or transfer depends on lender terms | Buyer assumption, prepayment, or buyout depends on the agreement |
| 2026 federal residential credit | The IRS says the Residential Clean Energy Credit is unavailable for property placed in service after December 31, 2025. Verify personal tax questions independently. | ||
The Consumer Financial Protection Bureau has reported that some solar-specific loans included markups and fees that increased the principal substantially above the cash price. That does not mean every loan is a bad choice. It means the comparison must be complete.
The installed price for the same system without solar financing.
The amount you actually borrow after any financing charges are included.
The interest rate and number of years determine far more than the first payment.
The complete scheduled amount paid if the loan runs to the end of its term.
A lease generally charges for use of the solar system. A power purchase agreement generally charges for the electricity the system produces. In both structures, a third party commonly owns the equipment. Read payment changes, minimum-production terms, maintenance, roof work, home-sale transfer, buyout, renewal, and removal provisions before signing.
Florida law provides sales-tax treatment for qualifying solar energy systems and an assessment treatment for qualifying renewable-energy devices. Those state provisions are separate from the federal residential credit that ended for new 2026 projects.
A cash purchase often has the lowest total cost because there is no loan interest or third-party ownership cost, but it requires the largest upfront payment. The best choice still depends on liquidity, opportunity cost, loan terms, and how long you expect to own the home.
Usually, yes. A solar loan generally finances a homeowner-owned system. The lender may hold a security interest, and payoff or transfer requirements vary, so review the credit agreement as carefully as the installation contract.
With a lease, the solar provider or financing company generally owns the system while the homeowner pays for access to it. The owner normally receives any available ownership-based incentives and is responsible for maintenance defined in the agreement.
The IRS currently states that the Residential Clean Energy Credit is not available for property placed in service after December 31, 2025. Do not allow a 2026 payment proposal to assume that credit without independent tax advice.
Availability and final terms depend on the project and finance provider.
