1. A method of manufacturing a shingled photovoltaic module controllable in length and width, the method comprising:
(a) preparing a bulk silicon substrate on which bus bar electrodes and finger electrodes are formed;
(b) primarily cutting the bulk silicon substrate along first cut lines parallel to the bus bar electrodes by laser scribing to divide the bulk silicon substrate into a plurality of unit cells;
(c) shingled-joining the plurality of unit cells to correspond to a length of each of a plurality of strings to form an intermediate processing junction substrate;
(d) mounting the intermediate processing junction substrate on a substrate fixing jig and secondarily cutting the intermediate processing junction substrate along second cut lines perpendicular to the bus bar electrodes by laser scribing to form the plurality of strings; and
(e) laminating surfaces of the plurality of strings using a protective member to form the photovoltaic module,
wherein the first cut lines are set to correspond to an interval between the bus bar electrodes, and
wherein the second cut lines line are set to correspond to a width of each of the plurality of strings constituting the photovoltaic module.
