A PV module is made up of many cells connected together, and the electrical behavior of PV module is similar to PV cells. Therefore, the PV module parameters are also similar to solar cell parameters.
The voltage from the PV module is determined by the number of solar cells and the current from the module depends primarily on the size of the solar cells. At AM1.5 and under optimum tilt conditions, the current density from a commercial solar cell is approximately between 30 mA/cm 2 to 36 mA/cm 2.
