Model of the Photovoltaic Module
Create a model of the PV module connected to a variable resistor. By adjusting the resistance, the voltage levels across the module are varied, allowing for the analysis of its performance under different electrical loads.

Model of the PV module connected to a variable resistor.
Parametrization
Parameterize the model using datasheet values from a commercially available module.

Set model parameters using Wolfram Language to match the module specifications.
Performance Analysis
As irradiance increases, the power produced by the module also increases but begins to decrease rapidly after reaching the maximum power voltage (37.6 V).

The model’s IV curves closely match those provided by the manufacturer, validating the simulation’s accuracy.
