The present invention relates to a photovoltaic power generation system including a deterioration detection function, wherein heat generation factors can be removed and efficiency deterioration in a power transfer process can be prevented by monitoring the generation of an inverse current and a deterioration state in real time in transferring power, which is generated by a photovoltaic panel, to an inverter, and selectively controlling the transfer path of power outputted from a breaker depending on whether or not the inverse current is detected. More specifically, the photovoltaic power generation system having a junction box including a fuse, the breaker, a diode and an output terminal comprises: a switching circuit arranged at the rear end of the breaker and enabling the output end of the breaker to communicate with either a first line connected to the input end of the diode or a second line connected to the input end of the output terminal by a control signal; a detection part for detecting an inverse current applied to the diode; and an integrated control part for generating the control signal for commanding the output end of the breaker to communicate with the first line if the inverse current is detected as a result of the detection of the detection part, generating the control signal for commanding the output end of the breaker to communicate with the second line if the inverse current is not detected as a result of the detection of the detection part, and transmitting the generated control signal to the switching circuit. |
