The introduction of photovoltaic systems is progressing rapidly with the expansion of demand for renewable energy. However, in recent years, accidents are seen in some systems due to natural disasters caused by strong winds and large typhoons. On the other hand, wind resistance tests have not been established to evaluate the strength of the support structures for PV system. In this paper, we develop the world’s largest test apparatus designed to examine the wind pressure resistance of the ground installed PV system. By using the apparatus, the testing method is reported to evaluate the strength of the support structures for PV system.
