Evaluate a solar loan from the written price, disclosures, repayment schedule, and contract—not from a promotional rate or product label. Missing terms remain missing until the seller or creditor provides them.
1. Request same-scope cash and financed prices
The CFPB's solar-financing issue spotlight, published August 7, 2024, says some solar-specific lenders include financing-related fees or markups in the loan principal and that consumers may not receive a clear comparison with the cash price. Request both prices in writing for the same equipment, labor, warranties, and services. A difference deserves an itemized explanation, but it does not by itself prove that a dealer fee exists, that a charge is hidden, or how a charge is treated under applicable law.
2. Keep the note rate and disclosures separate
The contractual interest or note rate drives the supported amortization schedule. APR is a separate comparison disclosure that may include certain fees; the CFPB explains the distinction in its interest-rate and APR guide. Where Regulation Z applies, also compare the disclosed amount financed, finance charge, and total of payments. Do not manufacture one field from another when the contract or disclosure does not provide it.
3. Read voluntary-paydown and reamortization terms exactly
The CFPB report describes consumer concerns about representations and omissions involving optional prepayments. The result depends on the individual agreement. Ask for the baseline payment schedule, any optional paydown amount and deadline, whether the loan reamortizes, and the payment schedule both with and without the paydown. Do not assume a tax credit will fund it, and do not assume every clause causes the same payment change.
4. Check security, transfer, prepayment, and warranty terms
Ask whether the creditor records a lien or fixture filing, what happens during a sale or refinance, whether the obligation can transfer, how release or subordination works, whether any prepayment charge applies, and who remains responsible for equipment and workmanship warranties. These terms vary by lender, product, property, and jurisdiction, so obtain the answers in writing and price the actual agreement.
Reconcile the complete payment ledger
Enter the contractual principal, upfront payment, note rate, frequency, schedule type, and term in the financing comparator. Its modeled total includes the visible closing payment and every visible monthly payment row. Enter APR, amount financed, finance charge, and total of payments only as disclosed comparison fields.
Solar is one piece of a bigger household-finance picture. For decisions that touch your taxes, retirement timeline, or home equity, it can be worth talking to a financial advisor through a directory like AdvisorWorld — alongside primary sources such as DOE, DSIRE, and the IRS.
