Commercial Financing Options

You can finance your commercial solar PV system two ways. You can purchase it outright with cash or through loans, making you the system owner. Or, you can obtain a lease or power purchase agreement (PPA) held by a third-party owner.

What loans are available to finance a solar PV system?

If you decide to purchase a system, you may use one or a combination of options: cash, property assessed clean energy (PACE) loan or a bank energy efficiency and renewable energy loan.

Property assessed clean energy (PACE) loan – This loan is approved based on the property, and not on personal or business credit. In the event of a property sale, the loan stays with the property and ownership transfers to the new building owner. There are 5-, 10- and 20-year payback periods and the interest will be based on the length of the loan. Check for PACE availability in your county or city. In California, use the CSE PACE Map.

Energy efficiency and renewable energy loan – Typically offered by credit unions or banks, these loans are a secured loan with low interest rates.

What is a lease or a PPA?

Other financing options include leasing a system or entering into a power purchase agreement (PPA). Both mean the system is third-party owned, and you pay per month. In a lease, you pay a fixed monthly rate no matter what your system produces. With a PPA, you pay a fixed amount for each kWh the system produces.

Both leases and PPAs have long contracts (20+ pages), so be sure to read and understand the entire agreement before you sign. The terms for a lease or PPA are usually 20 years.
