By connecting in series and in parallel, a desired output can be obtained.

FIG. 2 shows a state in which the solar cell modules 21, 31, 41 having the above structure are vertically connected and attached to the outer wall 10. In the solar cell module 31, the bent piece 33a is directed upward, and the bent piece 33a is engaged with the recess 46 of one adjacent solar cell module 41 facing the other, and the other adjacent solar cell is inserted into the recess 36. The battery module 21 can be connected by engaging the bent pieces 23a thereof,
It is fixed to the outer wall 10 by bolts 11.

When the solar cell module of the present invention is connected and fixed using the solar cell module, rainwater flows down from above due to the engagement of the bent pieces 23a, 33a having an L-shaped cross section with the recesses 36, 46. At this time, rainwater does not enter between the solar cell modules 21, 31, 41 and the outer wall 10 through the recesses 36, 46, and the durability of the outer wall 10 and the solar cell modules 21, 31, 41 is improved. .
