Then, the solar cell module 2 is attached to the attachment device 3 suspended and held as described above.

Thereafter, while the entire structure is connected to the beam structure 33 by the primary attachment means 15, the beam structure 33 is straddled and suspended outside the handrail 14 with the light receiving surface facing outward. Mounting device 3 for solar cell module device suspended in this manner
Are mounted at four places by using the holding metal fittings 25 by using the paired screw holes 26 on the back surface by operating from the inside of the balcony. The holding member 25 has a cushion material 34 on its back surface.
Are mounted, and have screw insertion holes 35 corresponding to the paired screw holes 26. A screw 37 is screwed into the screw hole 26 on the mounting device 3 side so that the holding metal member 25 straddles the fence structure 36 such as the handrail 14 or the like to fix the solar cell module device. The primary attachment means 15 may be left or removed after fixing.

Removal from the handrail 14 or the like may be performed by performing the above operation in reverse order. However, when the primary mounting means 15 is removed, the primary mounting means 15 must be mounted again and then removed. That is, in this solar cell module device, all of the attachment to the handrails 14 of the balcony can be performed by a simple operation inside the balcony,
Since there is no need to put the body outside the handrail 14 or the like, the mounting or removing operation can be performed safely. In addition, using the primary mounting hole 16, the mounting device 3 after the mounting and the handrail 1 are mounted.
