Abstract: A combined solar cell module includes a solar cell module, an end connection device, and an output connection device. The solar cell module includes first and second connection portions on opposite sides of a substrate, and connection lines which connect solar cells to the first and second connection portions. The first connection portion has a first holding space. The second connection portion has a second holding space corresponding to the first holding space in an up-and-down manner. First and second connection parts are within the first and second holding spaces respectively. At least one of the first and second connection parts is a magnetic material, and another one is a magnetic material or a magnetically attractable material. The end connection device and the first connection portion are detachable and connectable. The output connection device and the second connection portion are detachable and connectable, for outputting current generated by solar cells.
