<p>The present invention relates to a photovoltaic power generation system which is a frame assembly including withdrawal grooves and does not need a separate cable work when a cables are installed during a process of installing the photovoltaic power generation system using an assembly-type cable duct frame. The photovoltaic power generation system comprises a plurality of panel units including: solar cell panels which collect sunlight; junction boxes which are fixated on rear sides on the solar cell panels and include a cable; frames comprising side walls, which are vertically arranged along outlines of the solar cell panels and include the withdrawal grooves through which the cables can be withdrawn, reinforcing ribs, which are formed to be horizontally bent from upper end portions of the side walls toward the insides, and rubber packings, which are joined with inner circumferential sides of the withdrawal grooves, are inserted into the insides, and prevent damage to the cable; and ducts which horizontally cross the solar cell panels and cover the reinforcing ribs and the exposed cables joined by volts and nuts. Cables of the panel units adjacent to each other are serially joined with each other in a vertical direction.</p> |
