Finance Models – PPAs, Leases, and Asset Finance

For many businesses, the biggest question is how to pay for solar or batteries. Luckily, there are flexible finance models beyond upfront capex. An onsite Power Purchase Agreement (PPA) allows a third party to fund, own, and operate the system. You simply buy the electricity at a fixed p/kWh rate, usually lower than grid power. No upfront spend, no maintenance hassle. A private-wire PPA works similarly but connects your business to a nearby solar farm via a dedicated cable—great if your roof isn’t suitable. Alternatively, asset finance or leasing lets you spread the cost while still retaining ownership and tax benefits. Each route has trade-offs: PPAs suit businesses that want zero capex, while leases and asset finance are better if you want long-term ownership. The right model depends on your cashflow, tax position, and appetite for operating infrastructure.
