Model step
Auxiliaries
The system's own power consumption
Inputs used: Auxiliaries: continuous (fans, etc.), Auxiliaries: from power threshold, Auxiliaries: proportional to power, Auxiliaries: night consumption, Model the auxiliaries
What it is
A PV system consumes part of its own output: inverter and transformer cooling, tracker motors, monitoring, lighting and security. By day the draw has a constant part and a part that follows the output. At night a small draw remains. Tracker systems draw more than fixed ones.
Options
- Day and night draw: the auxiliary draw by day and by night, taken from the system's output
- Do not model: no auxiliary draw, with the entered values kept on the Losses tab
