Abstract: Disclosed are a high-power shingled photovoltaic string controllable in length and width and a method for manufacturing a module thereof. The method for manufacturing a high-power shingled photovoltaic module comprises the steps of: primarily cutting a bulk silicon substrate along a first cut line parallel to a bus bar electrode using laser scribing, thereby dividing the bulk silicon substrate into unit cells; forming an intermediate processing junction substrate by shingled-joining a plurality of unit cells according to the length of a string; forming the string by secondarily cutting the intermediate processing junction substrate seated on a substrate fixing jig, the intermediate processing junction substrate being cut along a second cut line that is perpendicular to the bus bas electrode and set according to the width of the string; and laminating a protective member on the surfaces of a plurality of strings to form a photovoltaic module.
