A modeling-based simulation tool with a graphical user interface (GUI) was developed to predict PV performance of bifacial systems. The model was validated by comparing it with performance data measured from East/West vertical bifacial arrays in different locations. The main outdoor test system is at the Turku University of Applied Sciences (TUAS) in Turku Finland (Lat. 60.44 N, Long. 22.29 E). The aim is to predict the energy yield from this system configuration in northern latitudes. The benefits from E-W vertical bifacial systems have been well documented and include higher energy yields, better load matching, reduction in soiling and snow covering, just to mention a few. Our study focuses on the accuracy of the model to reproduce collected data at the site, by using different sources of meteorological data.
