Study of performance evaluation of PV array by using power output - Correction of power loss accompanying PV array

摘要

Authors are studying the performance evaluation of the photovoltaic array (PV array) by using the power output. Even if the PV array operates normally, the power output is decreased by various power loss factors. Influence of these loss factors which gave it to the voltage and an electric current was examined, and generated power output corrected for these losses ware used as an evaluation standard of PV array. From these results, it became clear that 90% value of nominal power output must have been able to use for the performance evaluation threshold of PV array by correcting power output.
