This tutorial describes how to use the solar module physical model.
The physical model of the solar module can take into account variations of the light intensity and
ambient temperature. However, it requires many parameter inputs. Some of the parameters can be
obtained from manufacturer datasheets, while other parameters need to be obtained by trial-and-error.
In order to make it easier for users to define parameters for a particular solar module, a utility tool
called Solar Module (physical model) is provided in the PSIM’s Utility menu. This tutorial describes
how to use this tool through examples.
The solar module physical model has the following parameters:
Number of Cells Ns: Number of solar cells in series in a solar module
2Standard Light Intensity S0: Light intensity under standard test conditions, in W/m . This
2value is normally 1000 W/m .
oRef. Temperature Tref: Temperature under standard test conditions, in C.
Series Resistance Rs: Series resistance of each solar cell, in Ohm.
Shunt Resistance Rsh: Shunt resistance of each solar cell, in Ohm
Short Circuit Current Isc0: Short circuit current of the solar module at the reference
temperature, in A.
Saturation Current Is0: Saturation current of the diode in the model, ...
