Solar Loan Comparison: Dealer Fees, APR, and Risk

A solar loan comparison should look beyond the monthly payment. The most expensive loan can appear cheapest when the salesperson emphasizes a low promotional APR while hiding dealer fees, long repayment terms, balloon payments, or assumptions about tax credit recapture.

What To Compare Across Solar Loan Offers

Start with the cash price of the system. Then compare the financed price, APR, finance charge, term length, total of payments, dealer fee, prepayment penalty, lien or security interest, tax credit assumptions, and what happens if you sell the home.

Dealer fees deserve special attention. Some loans advertise a very low interest rate while increasing the principal through a lender-paid or contractor-paid fee that is effectively passed to the homeowner. If the financed price is much higher than the cash price, ask why.

Why Monthly Payment Is a Weak Metric

A 25-year term can make almost any system look affordable. But the total cost may be far above the equipment value, especially if the proposal assumes that the homeowner will apply the federal tax credit to the loan. If the homeowner is not eligible for the full credit, uses it for other needs, or receives it later than expected, the payment can jump.

Compare each loan against an independent credit union, home equity loan, or bank offer when possible. The best solar financing choice is usually the one with the clearest disclosures and lowest total cost, not the one the sales team prefers.

FAQ

What is the most important number in a solar loan?

The total of payments is usually more useful than the advertised monthly payment because it shows the long-term cost of principal, interest, and fees.

Are low APR solar loans always better?

No. A low APR can still be expensive if the system price was inflated through a dealer fee or if the term is stretched over decades.

Where can I learn about specific financing traps?

Use the solar financing scams guide to review dealer fees, PPA escalators, credit reporting, balloon payments, and prepayment penalties.
