WIND RESISTANCE TEST FOR PHOTOVOLTAIC ARRAY FRAME USING LARGE AIR PRESSURE CHAMBER

Abstract

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 validity of the support structures for PV system. In this paper, we report the result of evaluating the structural strength of a real scale ground installing type solar cell array by wind resistance test using dynamic wind pressure equipment which is the world's largest scale.
