A method for manufacturing a photovoltaic module, comprising, in the following order: at a stringing workstation, using a stringer to simultaneously solder at least two cell strings, and during a cell soldering process, soldering an interconnecting bar at a predetermined position, wherein the interconnecting bar is configured to connect the at least two cell strings in parallel; at the stringing workstation, performing an inspection on cells in the at least two cell strings to obtain cell images and cell inspection results, wherein the cell inspection results are used to determine whether a cell needs to be repaired, and the inspection comprises an electroluminescence inspection and an appearance inspection or the inspection comprises an electroluminescence inspection, a photoluminescence inspection and an appearance inspection; sending an image of a cell that needs to be repaired to a repair workstation if a cell needs to be repaired; automatically soldering bus bars (61, 62) at heads and tails of the at least two cell strings to form a cell module, wherein the bus bars (61, 62) are configured to connect the heads and the tails of the at least two cell strings in parallel; placing cell modules on a front plate glass in sequence, and marking a cell to be repaired if needed; determining whether a cell that needs to be repaired exists in the cell modules; when a defective cell that needs to be repaired exists in the cell modules, sending a repair procedure instruction, and delivering the front plate glass of carrying the cell modules to the repair workstation according to the repair procedure instruction; when no cell needs to be repaired in the cell modules, delivering the front plate glass of carrying the cell modules to a stacking workstation; at the stacking workstation, soldering together bus bars (71, 72) at tails of two adjacent cell modules (710, 720); laying a backside adhesive film and a backside board; and before laminating, performing a further EL inspection and a further appearance inspection; wherein the step of performing the inspection on the at least two cell strings at the stringing workstation comprises in a cell string soldering process, when an n th cell is soldered, inspecting previous n-1 cells on each cell string, wherein n is an integer or in a cell string soldering process, after an n th interconnecting bar is soldered, inspecting cells between an (n-1) th interconnecting bar and the n th interconnecting bar. at a stringing workstation, using a stringer to simultaneously solder at least two cell strings, and during a cell soldering process, soldering an interconnecting bar at a predetermined position, wherein the interconnecting bar is configured to connect the at least two cell strings in parallel; at the stringing workstation, performing an inspection on cells in the at least two cell strings to obtain cell images and cell inspection results, wherein the cell inspection results are used to determine whether a cell needs to be repaired, and the inspection comprises an electroluminescence inspection and an appearance inspection or the inspection comprises an electroluminescence inspection, a photoluminescence inspection and an appearance inspection; sending an image of a cell that needs to be repaired to a repair workstation if a cell needs to be repaired; automatically soldering bus bars (61, 62) at heads and tails of the at least two cell strings to form a cell module, wherein the bus bars (61, 62) are configured to connect the heads and the tails of the at least two cell strings in parallel; placing cell modules on a front plate glass in sequence, and marking a cell to be repaired if needed; determining whether a cell that needs to be repaired exists in the cell modules; when a defective cell that needs to be repaired exists in the cell modules, sending a repair procedure instruction, and delivering the front plate glass of carrying the cell modules to the repair workstation according to the repair procedure instruction; when no cell needs to be repaired in the cell modules, delivering the front plate glass of carrying the cell modules to a stacking workstation; at the stacking workstation, soldering together bus bars (71, 72) at tails of two adjacent cell modules (710, 720); laying a backside adhesive film and a backside board; and before laminating, performing a further EL inspection and a further appearance inspection; wherein the step of performing the inspection on the at least two cell strings at the stringing workstation comprises in a cell string soldering process, when an n th cell is soldered, inspecting previous n-1 cells on each cell string, wherein n is an integer or in a cell string soldering process, after an n th interconnecting bar is soldered, inspecting cells between an (n-1) th interconnecting bar and the n th interconnecting bar.
