Open your job roomPaying for your solar system
Three common ways. Compare the total you will repay, not the monthly payment.
- Home equity line of creditBorrow against what your home is worth. Rates are usually lower, but your home secures the loan, and approval takes a few weeks.
- Personal loanNo collateral and a fast answer. Rates are usually higher and you repay sooner.
- Contractor financingMany contractors offer a plan through a lender. Get the rate, fees and total cost in writing, then compare it with your bank.
