Potential power irradiance only

This signal calculates the potential power given Irradiance and Capacity. irradiance cut-in and degradation factor are also applied if the corresponding metadata values are available.

Required metadata fields:

Capacity (kW), set per inverter

Optional metadata fields:

Technology

Solar

Equation

For each time step, it is calculated like this:

I is the irradiance for each time step, with cut-in applied if the Availability Irradiance Cut-In metadata field is available

ISTC is irradiance used under Standard Test Conditions (1000 W/m2)

If Degradation factor and Commissioning Date metadata values are available, the degradation will be applied to the resulting potential power.
