The number most proposals hideAsk for the cash price beside the financed price.
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.
Cash priceThe installed price for the same system without solar financing.
Financed principalThe amount you actually borrow after any financing charges are included.
APR and termThe interest rate and number of years determine far more than the first payment.
Total of paymentsThe complete scheduled amount paid if the loan runs to the end of its term.
Lease and PPA are related, but not identical.
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-specific facts still matter.
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.
