A solar-battery array comprising a plurality of solar batteries, which is characterized by satisfying the relationship of V2 < 0 and V1 + V2 > 0, where V1 is the voltage to ground of the positive-pole terminal at the time of maximum output of the solar-battery array, and V2 is the voltage to ground of the negative-pole terminal at the time of maximum output of the same and a photovoltaic power generation system having such an array are disclosed, whereby the effects of an electric shock on the human body can lessen even when you touch any electric circuit of the solar-battery arrays. <IMAGE> |
