Abstract
The utility model provides a welding base plate of a photovoltaic assembly. The base plate is provided with a battery string placing area and a guiding line area on a side of the battery string placing area. The guiding line area is provided with a solder strip guiding line and a bus bar guiding line. The base plate of an overlapping area of the solder strip guiding line and the bus bar guiding line, that is an area corresponding to soldering points of the solder strip and the bus bar on the surfaces of the solder strip guiding line and the bus bar guiding line, is hollowed out. Thus, placing positions of the solder strip and the bus bar can be marked by the guiding lines, so an operator can be guided to lay the solder strip and the bus bar according to the guiding lines, and soldering point positions of the solder strip and the bus bar are more standard and accurate. Since the base plate corresponding to the area of the solder strip and the bus bar is hollowed out, the soldering points are hung in the air in welding, and the soldering points do not contact any object, so obvious irregular welding marks would not be generated. The welding base plate is clean, tidy, and beautiful in appearance, and appearance quality of the front surface of the photovoltaic assembly is improved.
