PVArrayValidation presents a ramp DC voltage source in parallel with an instance of the PVArray model. The voltage ramp is configured to sweep from -10 volts to 35 volts in 1 second. This provides the enough voltage range to cover all of the PV array's working range when initialized with default values.
To use the example, simulate the model and start by displaying both voltage and current of the ramp voltage source. A figure like the following should be displayed:
Notice how the variation in the current delivered by the PV array (sinked by the voltage source) reflects the familiar PV module curve.
Modify the values for the irradiance and temperature blocks and see how these changes are reflected in a change in the PV curve, accurately reflecting the effects of these variables in the PV module performance.
