Abstract:
A photovoltaic power generation system comprising:a solar cell array having a plurality of solar cells electrically connected to each other with a wiring member; a power conditioner for converting an output from the solar cell array into AC power; an insulation transformer provided between the solar cell array and a power system; a ground-fault interrupter provided between the power conditioner and the power system; and a ground-fault detector for detecting a ground-fault of the solar cell array, wherein a part of at least one of an electroactive portion of the plurality of solar cells and an electroactive portion of the wiring member is exposed to the outside, wherein a line of the solar cell array is grounded, wherein the ground-fault detector is provided at the grounded line, and wherein a set current value at which the ground-fault detector judges a ground-fault is larger than a set current value at which the ground-fault interrupter interrupts.
