PHOTOVOLTAIC POWER GENERATION PANEL OR SOLAR CELL ARRAY

PROBLEM TO BE SOLVED: To provide a photovoltaic power generation apparatus capable of enabling, in the case of individual operation, a user or a construction worker to easily check by sight a power generation state thereof outdoors and ensuring electrical safety in combination with an individual operation detection function of an inverter.SOLUTION: A photovoltaic power generation apparatus is configured so that operation display means with a light emitter for displaying an operation state of a photovoltaic power generation panel is electrically connected with an output terminal thereof and provided on or in the vicinity of the photovoltaic power generation panel, while a transfer cut-off signal receiver which outputs a commercial power supply system power failure detection signal to the operation display means in response to a transfer cut-off signal output from a transfer cut-off signal transmitter provided on a commercial power supply system is provided on the commercial power supply system, and the operation display means is driven upon reception of the commercial power supply system power failure detection signal, thus allowing a visual checking of a power generation state of the photovoltaic power generation panel from the outside.
