Array and AUX Losses
Compute the losses incurred at the power conversion station. These losses are comprised of parasitic loads for inverter cooling, tracker actuator, and auxiliary loads such as the data acquisition system, lighting, etc.
Note the following preconditions before performing the calculations:
a.) The tracker actuator loss PL,Tracker is only applied during daylight hours at Arrays which host one or more tracker DC Fields.
b.) The inverter cooling load loss PL,Cooling is only applied during daylight hours when the inverter is operating.
c.) The auxiliary loss PL,DAS is present for all hours of the day.
1.) Find the power at the input terminal of the Array transformer.
