Cash, Loan, or Lease? Compare Solar Financing Without the Fine Print

Ask for two prices

Request the cash price and the financed price for the same equipment and scope. A low promotional interest rate may include a substantial financing fee in the project price. The payment can look attractive while the total cost tells a different story.

The Consumer Financial Protection Bureau reported that some solar-specific loans included markups and fees that increased the loan principal by 30 percent or more above the cash price. The practical response is not to reject every loan; it is to compare the complete borrowing cost and alternative financing sources.

Understand who owns the system

With cash or a typical solar loan, the homeowner owns the system. With a lease or power purchase agreement, a third party commonly owns it. Ownership affects incentives, maintenance duties, insurance questions, home-sale steps, and what happens at the end of the agreement.

A lease usually charges a scheduled amount for use of the system. A PPA usually charges for the electricity produced. Either may include payment increases over time. Ask for the full schedule, not only the first-year rate.

Compare the complete obligation

• Cash price and financed principal
• Interest rate, term, fees, and total of payments
• Whether any payment changes or escalates and when
• Prepayment, buyout, end-of-term, and transfer requirements
• Who owns the system and receives any incentives
• Who pays for service, monitoring, removal, and reinstallation
• What happens during a home sale or roof replacement

No proposal should depend on a tax promise

Solar companies are not your tax advisor. The IRS says the Residential Clean Energy Credit is unavailable for property placed in service after December 31, 2025. A 2026 proposal that automatically assumes a 30% residential federal credit deserves immediate scrutiny. Confirm tax questions independently.
