Description (excerpt):
Grid parity for photovoltaic (PV) technology is defined as the point where the cost of PV-generated electricity equals the cost of electricity purchased from the grid. Achieving grid parity is a function of many variables, including the solar resources, local electricity prices, and various incentives. In this report, we evaluate some of the key drivers of grid parity both regionally and over time. We begin by considering a base-case scenario, which includes a single set of assumptions for financing, technical performance, and several other factors. We also consider how grid parity may change over time considering the evolution of PV technical performance, financing parameters, electricity prices and rates, and policies.
