    FAQs about Automatic installment payment for photovoltaic cabinetized systems

    Can you finance solar panels without a down payment?

    Fortunately, there are options for financing solar panels that make it possible to benefit from solar energy savings without paying the hefty upfront cost. Many of these also offer little to no down payment, allowing homeowners to make the switch even if they don't have a lump sum of savings to invest.

    How do you pay for a solar system?

    There are three main ways to pay for your home solar system: upfront with cash, a solar loan, or through a lease or power purchase agreement (PPA). If you can't afford to pay for your system out of pocket—or don't want to tie up that capital—solar financing allows you to spread the cost over time through a loan or lease.

    Should you buy solar panels with cash?

    If you have enough saved up, buying solar panels outright with cash payments will provide the greatest savings, for the simple fact that you avoid interest payments that come with solar loans.
