Program Overview

The California Solar Initiative (CSI) is designed to promote solar technologies and help lower the cost of solar systems that will serve California’s needs. CSI has set a goal of creating 3,000 megawatts (MW) of new, solar-generated electricity by 2017, moving our state toward a cleaner energy future.

Who Benefits from the Program?

The California Public Utilities Commission (CPUC), through its California Solar Initiative, provides over $2.1 billion in incentives for existing commercial, residential, industrial and agricultural properties.

Incentives

The program is intended to encourage high-performing solar systems, and incentives differ depending on the type of property and size of the system.

Expected Performance-based Buydown (EPBB)

The program provides a one-time, up-front payment based on an estimate of a solar system’s future energy generation performance. Systems with larger capacities receive greater incentives.

Performance-based incentives (PBI)

Performance-based incentives are required for solar projects with a system larger than 30 kilowatts (kW). Monthly incentive payments for five years are based on the actual energy generated by the system as measured by a separate performance meter. Even if solar projects are less than 30 kW, you can apply for this incentive as long as your system is greater than 10 kW.

Incentive Rate

The incentive rate is based on the incentive type—EPBB or PBI, and the relevant customer segment—residential, commercial or government/nonprofit and current incentive step.

The PBI Customer Manual (PDF, 418 KB) has a detailed description of the PBI payment process.
