Miniaturized Model Kit for Yield Measurements of PV Systems — Concept and Application

In a previous work, we have shown that miniaturized test systems can be used to reproduce the energy yield of larger systems accurately. Accordingly, such miniaturized systems can be used to evaluate varying system concepts or to reveal differing properties in direct, comparative measurements. The smaller size enables a considerably increased flexibility and a fast realization compared to full sized test fields. Based on such measurements, optimized system configurations can be found or a yield prediction can be made. This is of interest for PV systems and technologies for which simulation tools with sufficient or validated accuracy are not available. Examples are bifacial modules, particularly with steep tilt angles or Perovskite cell types. In this paper, we report on a commercially available miniaturized model kit to reproduce measurements of PV systems. It is an improved version of the previously used test rig that allows a flexible arrangement of the modules to represent various types of PV systems.
