PURPOSE: A photovoltaic power generating system is provided to prevent a disconnection or conduction failure by including an extensible cable which connects a solar cell module to a junction box. CONSTITUTION: A cable(300) electrically connects a junction box to a solar cell module. A cable length control unit(400) includes a housing(410), a slide member(420), and a connection cable(430). The connection cable is connected to the slide member and the housing. One end of the connection cable is fixed to a cable fixing member(440). The slide member is movably installed along a vertical direction of the housing. |
