What is a CEC-AC watt?
To measure nominal output power of photovoltaic cells or module to determine the system’s rating and subsequent incentive calculation, the Program Administrators will use the California Energy Commission’s CEC_AC rating standards, which are based upon 1,000Watt/m2 solar irradiance, 20 degrees Celcius ambient temperature, and 1 meter/second wind speed. The CEC-AC rating is lower than the Standard Test Conditions (STC.
