This EPBI calculator is a tool available to participants of the Pacific Power California Solar Incentive Program to determine appropriate incentive amount based on a reasonable expectation of performance for an individual system. The EPBI Calculator has also been created for consumer's to educate themselves on the differences of solar system design and how changes to the PV system's specifications will produce different kilowatt hour results over the course of a year. Please be aware that actual performance of an installed PV system is based on numerous factors, including some factors that may not be considered in the EPBI Calculator. While this calculator relies on industry-standard assumptions, and is driven by NREL's PV Watts v.8 calculator, there may be other factors that affect the output of your PV System.

Notes:

  1. EPBI Incentive = Confirmed Incentive Rate x PPCSIP Rating
  2. CEC-AC System Rating (kilowatts) = Quantity of Modules x PTC Rating of PV Modules x CEC Inverter Efficiency Rating / 1000 (watts/kilowatt)
