What it is

The constant power the system's own equipment draws while the system exports above the power threshold: fans, tracker motors, control and monitoring systems. The field is in watts; the API takes kilowatts.

Typical values and how to get it

From the system's auxiliary load list; a few kilowatts per megawatt, more for tracker systems. If not given: 0 kW: no constant auxiliary load.
