Photovoltaic module and manufacturing method thereof

A method for manufacturing a photovoltaic module, wherein the photovoltaic module comprises

• a laminate including a solder strip;
• and a junction box arranged on a surface of the laminate and including a plate connected to the solder strip by laser soldering;
• wherein the plate has a first region and a second region, in which a region covered by the solder strip on the plate is the first region, and a region not covered by the solder strip on the plate is the second region;
• and wherein a soldering seam formed by the laser soldering includes a first soldering seam and a second soldering seam, the first soldering seam is located in the first region, and the first soldering seam extends through the solder strip into the plate along a thickness direction of the laminate, the second soldering seam is located in the second region, and the second soldering seam extends directly into the plate along the thickness direction of the laminate,
• wherein the method for manufacturing a photovoltaic module comprises:
• providing the laminate;
• arranging the junction box on the laminate so that the solder strip of the laminate extends into the junction box;
• acquiring a position of the plate;
• pressing the solder strip against the plate in the junction box;
• laser-soldering the solder strip and the plate by using a laser head, so that a first soldering seam formed after soldering extends through the solder strip into the plate, and a second soldering seam extends directly into the plate;
• and
• visually inspecting the first soldering seam.
