Popis: PV systems using bifacial modules have gained a lot of interest in recent years. Due to the bifacialty of the modules the energy yield of the systems can be enhanced compared to monofacial ones depending on the installation conditions. While bifaciality enables a larger variety of promising installation options, it is difficult to simulate or to predict the output with sufficient accuracy and a realization of test fields is an extensive task. In this work, we use a miniaturized test rig as an alternative approach for the appraisal of specific installation situations. The small size allows a quick realization of layouts and comparative outdoor power measurements at identical irradiance conditions. By means of this tool, we analyze the performance of PV systems using vertically installed, east/west-orientated, bifacial modules in combination with different grounds in comparison to state-of-the-art, east/west oriented, monofacial PV systems with low tilt angles by means of simulations and measurements. Special emphasis is given to east/west-oriented modules in combination with highly reflecting foils with and without the use of ground sculptures that lead to a weak light concentration effect.
