Bifacial PV system in Aichi Airport-site Demonstrative Research Plant for New Energy Power Generation

NEDO Demonstrative Project of Regional Power Grids with Various New Energies includes several kinds of FC system and PV system with sodium–sulfur battery. One of the PV systems is vertically installed fence-type bifacial PV system, 30 kW for its front surface Pmax. The bifacial PV worked as an outer fence of the global loop in the EXPO 2005 Aichi, Japan. The whole generation system was moved from the site of the EXPO 2005 to the site near the Aichi Airport, and then it re-started its power generation in September 2006 as the Aichi Airport-site Demonstrative Research Plant for New Energy Power Generation, where the bifacial PV array was installed on the ground faced to southwest and northeast. The paper introduces the outline of the plant and describes the evaluation of actual yearly generation of the bifacial PV system.
