The invention relates to the technical field of photovoltaic module production, and particularly discloses a double-glass photovoltaic module manufacturing method, which comprises the following steps of: 1, performing power and current grading on solar cells, and marking the solar cells as different grading levels according to different grading levels; 2, connecting a plurality of solar cells with the same grading level in series to form a cell string through a welding strip; 3, connecting a plurality of battery strings in parallel through a PET plastic package bus bar, and then sequentially stacking the front glass, the upper packaging adhesive film, the battery strings, the lower packaging adhesive film and the back glass for laying; step 4, performing appearance detection and electroluminescence test on the laid product before lamination; and 5, laminating to obtain a laminated piece. According to the invention, the PET plastic package bus bar is adopted to replace a common bus bar, an insulating cushion l
