Combined solar cell module

A combined solar cell module, comprising:

• at least one solar cell module, comprising:
• a substrate having a first opposite side and a second opposite side opposite to each other;
• a plurality of solar cells, located on the substrate;
• a first connection portion, disposed on the first opposite side of the substrate, and having a first holding space therein;
• a second connection portion, disposed on the second opposite side of the substrate, and having a second holding space therein;
• a plurality of first connection parts, respectively disposed in the first holding space;
• a plurality of second connection parts, respectively disposed in the second holding space, wherein a shape of the second holding space disposed with the plurality of second connection parts matches a shape of the first holding space disposed with the plurality of first connection parts in an up-and-down manner, so that exposed surfaces of the plurality of second connection parts correspond to exposed surfaces of the plurality of first connection parts in an up-and-down manner, and at least one of the plurality of first connection parts and the plurality of second connection parts is a magnetic material, and another one of the plurality of first connection parts and the plurality of second connection parts is a magnetic material or a magnetically attractable material;
• and
• a plurality of first connection lines, connecting the plurality of solar cells to the plurality of first connection parts and connecting the plurality of solar cells to the plurality of second connection parts, respectively, so as to transmit current generated by the plurality of solar cells to the plurality of first connection parts and the plurality of second connection parts via the plurality of first connection lines;
• an end connection device, being detachable and connectable to the first connection portion, and configured to electrically connect the plurality of first connection parts;
• and
• an output connection device, being detachable and connectable to the second connection portion, and configured to electrically connect the plurality of second connection parts and output the current generated by the plurality of solar cells.
