As shown in FIG. 4, the conventional manufacturing process of the conventional solar cell module includes the steps of: Teaching S10, string S20, array S30, module setting S40, and lining step S50 can do.

The teabing step S10 is a step of bonding the ribbons 24 to both surfaces of each solar cell 20. That is, when the ribbon 24 is connected to the bus bar 23 and then heated, the soldering alloy layer 26 of the ribbon 24 is melted and the ribbon 24 and the bus bar 23 are soldered.

The string step S20 is a step of forming a string 29 by serially connecting the solar cell 20 to which the ribbon 24 manufactured in the teabing step S10 is connected.

The array step S30 is a step of arranging the string 29 manufactured in the string step S20 in a plurality of rows on the sealing material 16 placed on the glass plate 12, (27), and forming a terminal (28) connected to the outside.

In addition, since the equipment in which the teabing step S10 and the string step S20 of the solar cell 20 are performed and the equipment in which the array step S30 to the lamination step S50 are performed are different from each other, It is necessary to equip various kinds of equipments for transporting the solar cell 20 between the equipments, thereby increasing the cost of equipments to be provided, There is a problem that is required.

As a result, when a solar cell module is manufactured, it may cause a manufacturing defect and an increase in unit price, and may cause durability and reliability when installed in an actual field.
