The consideration on maximum output point of the photovoltaic power generation system

摘要

In dividing the PV array into unloaded and loaded condition, measurement of irradiance, panel temperature, voltage, current and electric power were made to be the identical time. In this report, the loss in maximum output point of the PV array was quantitatively evaluated using measurement data on September fifth, 2001. As the result, in present state, the mismatching of PV array and power conditioner was 8.0%. In addition, it was proven that the mismatching was improved at 1.0%, when the input voltage was assumed with 285V.
