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.
