What is PPA Model?

The PPA model stands for the Power Purchase Agreement model. Under the PPA model, the power purchaser provides space (land, rooftop, etc.) on which the PPA provider installs and operates a photovoltaic system for free. At the same time, the PPA provider measures the amount of power used and charges accordingly, while the power purchaser pays for the electricity bill.
