To provide a method for easily and firmly fixing a roof material in which a solar cell is formed on the surface of a corrugated galvanized plate when fixing the roof material from the surface side of the solar cell, without rainwater intrusion, without peeling a thin film of the solar cell, and without corrosion of the galvanized plate at contact parts with nails and the like.
In order to mounting a solar cell 1 on the surface of a corrugated galvanized plate 2, the corrugated galvanized plate 2, on the surface of which nuts 6 are fixed by forming arc-welding parts 13 or metallic adhesive parts 13, is formed, thereby mounting a spherical silicon solar cell module (output 115 W) on the surface of the corrugated galvanized plate 2 by using the nuts 6. Moreover, styrene foam plates 9 having a shape similar to that of roof tiles are interposed in an intermediate position in a sandwich-shape and the solar cell 1 is formed on the surface of the corrugated galvanized plate 2.
