Understanding your solar loan calculator results

Monthly payment: This is the amount you’ll pay each month toward your loan.

Total interest paid: This is the interest amount you’ll pay over the lifetime of the loan. Interest rates on solar loans range from about 6% to 36%, and the rate you receive depends on your credit, income, existing debt and other factors. Borrowers with high credit scores and little debt often get the lowest interest rates.

Total payments: This is the amount you’ll pay by the end of the loan, including the loan principal and interest.
