Abstract: PV systems using bifacial solar modules have shown an increased energy harvest compared to systems with standard, monofacial panels. Due to bifaciality of the modules, the tilt angle, the installation height, the distance between the modules and in particular the ground reflectance have a significant influence on the energy harvest. For bifacial module arrays reflective elements in between the rows might be an option in order to achieve a low light concentration resulting in a further increased energy harvest. A simulation of such conditions is hardly possible; measurements at real systems would require considerable effort. In this work we present results obtained by a measuring setup with rotating mini modules. In particular the influence of the ground reflection was studied by using various grounds and reflecting elements with different shapes. Prior to the analysis of the reflector elements the measurement setup is described and the assignability of results from the miniaturized test array to a corresponding large scale system is demonstrated.
