According to the above-described embodiment, when installing the solar cell module 1, the worker faces the ridge side,
The solar cell modules 1 (metal roofing material 2) are sequentially arranged on the field plate 9 from the ridge side, and the fixing portions 35 of the suspension 5 are fixed to the fields by using the mounting holes of the fixing portions 35 of the suspension 5 with the nails 66. It is fixed to the base plate 9 and the rafter 67. Further, since two positive lead wires 62 and two negative lead wires 63 protrude from the terminal box 53 of the solar cell 4, as shown in FIG. When the batteries 4 are sequentially connected in parallel, for example, the solar cells 4 of the adjacent solar cell modules 1 are connected to the plus-side lead wires 62 and the minus-side lead wires 63 to the connectors 62 a and 6 sequentially.
The connection may be made through the connection 3a, and the solar cell 4 can be connected very easily.
