When a retail store, winery, or factory thinks about going solar, they often finance through a solar power purchase agreement (solar PPA). Both allow your business to go solar with no up front costs. But if you're in California, there's new way to finance solar with no upfront cost, and it's called Property Assessed Clean Energy or "PACE."
PACE is a win-win for both the business that wants to go solar and the PACE lender. It's a win for the business because it can own a solar system with no upfront costs, get free electricity for 20 years, plus receive any available solar rebates and tax incentives. It's a win for the lender because the PACE loan is paid back through a special tax assessment on the business's property, which makes the loan extremely secure, even from bankruptcy.
