Solar cell panel and method for manufacturing same

A method for manufacturing a solar cell panel, comprising:

• providing a plurality of solar cells including first and second solar cells electrically connected to each other;
• providing a wiring material including a process of increasing yield strength of the wiring material;
• attaching a first extension wiring and a second extension wiring to each of the plurality of solar cells;
• putting the first solar cell as it is, rotating and putting the second solar cell by 180°, and arranging the first extension wiring of the second solar cell on the second extension wiring of the first solar cell so that the first extension wiring of the second solar cell overlap a portion of the first solar cell;
• forming a fixing portion in at least a portion of a connection portion where the first extension wiring and the second extension wiring overlap and are connected to constitute at least one solar cell string;
• and
• laminating a first cover member, a first encapsulant, the at least one solar cell string, a second encapsulant, and a second cover member and applying heat and pressure to the laminated first cover member, first encapsulant, at least one solar cell string, second encapsulant, and second cover member to integrate the stacked first cover member, first encapsulant, at least one solar cell string, second encapsulant, and second cover member.
