Impact of volcanic ash on CPV system in Miyazaki Japan

Abstract

Recently, large-scale photovoltaic (PV) systems have attracted attention. In the field-operation, the electric power generations of PV systems, including CPV system, are affected by the natural environment such as ambient temperature, snowfall, soiling, etc. In this study, we assessed the impact of the volcanic ash on CPV system, and the output characteristics of the CPV and CIS systems were compared. The output of CIS PV system was drastically decreased by the volcanic ash. On the other hand, in the case of the CPV system, the output was not decreased so much. © 2012 American Institute of Physics.
