<p>Disclosed is a method for manufacturing a solar cell module, wherein connecting performance of a wiring tab is improved by increasing the solder quantity of the wiring tab without requiring additional operations, such as additional soldering. The method is provided with a step wherein one unit is formed by connecting the rear side electrodes of a plurality of solar cells using a rear side wiring tab (21) having a solder layer (21b) provided on the circumference thereof, and a front side wiring tab (20) that connects the front side electrodes of the adjacent units (1, 1) is connected to the rear side wiring tab (21). The method is provided with: a first welding step wherein the rear side wiring tab is connected to each of the rear side electrodes; and a second welding step wherein the front side wiring tab (20) and the rear side wiring tab (21) are connected to each other in a rear side wiring tab (21) region where the solder layer (21b) is not welded in the first welding step.</p> |
