Commercial Solar Energy Rebates & Credits

The State of California offers substantial rebates for both large and small commercial solar electric systems through the California Solar Initiative (CSI). Depending on the size of your facility, you will qualify for either the Expected Performance Based Buydown (EPBB) or a Performance Based Incentive (PBI) program.. These rebates can cover as much as 40% of the total system cost.

Expected Performance Based Buydown (EPBB)

This program offers upfront rebates for systems less than 100kW in size. The program is part of the California Solar Initiative, which started accepting applications on January 1, 2007

Rebate amounts are determined by a number of factors, including system location, orientation, shading and size. These rebates generally cover 20-35% of the total installed system cost.

Performance Based Incentive Program (PBI)

This program offers rebates based on energy production over the course of 5 years. Rebates are paid to the system owner monthly, based on reported energy production. This program is designed to benefit entities installing larger commercial or public sector projects. Typically, the PBI will cover more than 30% of the installed system cost. For some businesses, this type of program may be more advantageous than the upfront rebate offered by the EPBB. A Borrego Solar Energy Consultant will be able to determine which program is best for you, based on the specifics of your business.

The level of both of these rebate programs will decline as the program reaches scheduled participation milestones. Therefore, the longer a business waits to install a solar electric system, the lower the rebate will be.
