Technical Brief: Realistic Parameters for Bifacial Modeling

Looking to improve utility-scale bifacial modeling best practices, researchers from Array Technologies, PV Lighthouse, and CFV Labs recently concluded a long-term field study. The  goal was to define current modeling limitations and vaildate inputs based on real-world testing.

Accurate modeling of utility-scale bifacial PV is essential to set realistic expectations for the technology’s performance. Most utility-scale software programs, including PVsyst, use a simplified 2D View Factor model to calculate the irradiance contribution from the rear side of a bifacial module. This technical brief gives you validated inputs for bifacial modeling.
