modelPVArray
Array of PV modules
Information
Model of a PV Array used in DIgSILENT's implementation of the PV plant. Provides optional inputs of irradiance (E) and temperature (theta). If those inputs are not connected, the model set temperature to 25 °C and irradiance so that it matches the specified initial power production.
