Solar Financing Dealer Fees: Why the Monthly Payment Can Mislead
Learn how dealer fees and loan structure can change total solar cost, and which numbers to request before comparing a monthly payment.
Quick answer
A low solar payment can come from a long term, a financing charge, or both. Compare the cash price, financed amount, APR, term, total payments, and any dealer fee in writing.
Cash price and financed price are different
The system’s installed cash price is a useful comparison baseline. A loan can add interest and fees, so the financed total should be shown separately rather than hidden inside a monthly number.
APR helps compare loans
Annual percentage rate combines interest and certain finance charges into a standardized borrowing measure. It does not replace reading the full loan agreement, but it helps compare options with different structures.
Request a complete payment schedule
Ask for payment count, monthly payment, total of payments, assumed prepayments, and any payment changes. Do not compare a 25-year payment with a 10-year payment as if they represent the same cost.
Keep energy savings separate
A forecasted utility-bill reduction is not loan income. Compare the financing cost and modeled energy value as separate lines, with assumptions stated clearly.

Frequently asked questions
Is a dealer fee always disclosed?
Ask directly for every finance charge and compare the cash price with the financed amount in writing.
