Performance indices for parallel agriculture and PV usage

Abstract: In 2016, Fraunhofer ISE installed Germany’s largest APV research facility near Lake Constance with a capacity of 194.4 kWp. Experiments were deducted over a crop rotation of potato, celery, clover grass, and winter wheat. In the first
year, the average results amounted to approximately 20% lower yields for both the agricultural and electrical layer leading to a LER of 1.6 or a rise of land use efficiency of 60% which is illustrated in Figure 46.
Since the installation of the pilot plant, with 1.87 the highest LER was observed in the dry and hot summer 2018 for celery, which indicated a 12% rise of yield compared to the reference area.
Regarding the electrical performance of the APV system, ZENIT, a software tool developed by Fraunhofer ISE [63], was employed to simulate the overall electrical yield of a standard GM-PV system implementing a chain of loss models. With
78.1 kWp/m², the installed capacity of the reference scenario was 39% higher compared to the capacity of the APV system.
Due to the application of bifacial modules in the APV system, though, the measured field results of the APV system were only 17% below the simulated results of the GM-PV system
