In PVsyst, bifacial modules are characterized by their Bifaciality Factor (ϕ), which is defined by the IEC 61724-1 standard as the ratio of the nominal efficiency of the rear side to that of the front side. Remember that the nominal efficiency is simply the nominal Power (under STC) expressed in [kWp], divided by the area of the PV module [m²].
Bifaciality, also known as the bifacial factor or bifacial ratio, measures the ratio of the power generation capabilities of the back and front of bifacial modules under standard testing conditions, playing a vital role in evaluating the performance of bifacial solar panels.
For defining a bifacial module in PVsyst, please use the concerned checkbox in the PV module definition dialog, page "Size and technology". In PVsyst, bifacial modules are characterized by their Bifaciality Factor (ϕ), which is defined by the IEC 61724-1 standard as the ratio of the nominal efficiency of the rear side to that of the front side.
For example, under Standard Testing Conditions (STC), if the test power of the back of a bifacial photovoltaic module is 350 watts and the test power of the front is 500 watts, the calculation for bifaciality would be 350/500 = 70%. This means that the back contributes 70% of the power generation capability compared to the front.
