US 2021/0343887 A1 · METHOD OF MANUFACTURING SHINGLED SOLAR MODULE AND THE SHINGLED SOLAR MODULE

Abstract

The present disclosure relates to a method of manufacturing shingled solar module and the shingled solar module. The method includes steps of: arranging solar cells and conductive sheets on a top surface of a bottom package feature along a second direction in a shingled manner into a plurality of solar cell strings, wherein the conductive sheets are disposed at trailing ends of the solar cell strings, and the solar cell strings are arranged along a first direction perpendicular to the second direction to form a cell array; arranging a first busbar and a second busbar on a top or a bottom or the cell array, where the first busbar is in contact with main grid lines of the solar cells at initial ends of the respective solar cell strings, and the second busbar is in electrical contact with the conductive sheets of the respective solar cell strings; and laminating a combined feature comprised of the top package feature, the cell array, and the bottom package feature. In the method according to the present disclosure, the arranging step and the shingling step are combined as one step, in which the cells are shingled and arranged directly on the bottom package feature . In this way, the method is advantageous for operation and can be implemented efficiently at low costs.
