Using an equivalent circuit model, the output characteristics of a bifacial photovoltaic solar module under various shaded conditions of the back side of the module were analyzed in detail. From the dark current-voltage (I-V) characteristics of bifacial photovoltaic solar cell, the diode parameters were extracted. The extracted diode parameters were applied to the equivalent circuit model for the bifacial photovoltaic solar module, and the solar-module performance was calculated. There was good agreement between the measured and calculated IV characteristics of the bifacial photovoltaic solar module under various shaded conditions.
