Abstract
The invention relates to a method for connecting photovoltaic module battery pieces. Positive electrode wire outgoing end battery pieces and negative electrode wire outgoing end battery pieces are two adjacent lines of battery pieces located in the middle of a module in the width direction. Bus bars are only located at the wire outing ends of the battery pieces located between the first row and the second row of the module and are connected with a junction box. The positive electrode of each battery piece is connected with the negative electrode of the next battery piece in series through a solder strip in the direction of the row or the line from the wire outgoing end positive electrode battery pieces, and the negative electrode of each battery piece is connected with the positive electrode of the next battery piece in series through a solder strip in the direction of the row or the line from the wire outgoing end positive electrode battery pieces. If the included angle between the connecting directions of three adjacent battery pieces is 90 degrees, the welding direction the solder strip of the electrode on the front side of the second battery piece is perpendicular to the welding direction of the solder strip of the electrode on the back side of the second battery piece. Compared with a traditional connecting mode, the method for connecting the photovoltaic module battery pieces has the advantages that the number of adopted bus bars can be greatly reduced, material cost can be reduced, serial resistance of the module can be reduced, and the purpose of improving the efficiency of the module is achieved.
