Then, first, an elastic spacer having an insertion hole is fitted into the shaft portions of the first and second bolts, and then the installation surface is attached to the installation surface according to claim 1, 2, 3 or 5. While mounting the solar cell module, a bolt insertion hole of the first fixing member is formed on the shaft portion of the first bolt, and a bolt insertion hole of the second fixing member is formed on the shaft portion of the second bolt. Respectively, and finally, nuts are screwed onto the shaft portions of the first and second bolts, and the nuts and the first and second bolts are tightened to fasten the first and second fixing members. The solar cell module according to claim 7, wherein How to install. 9. A substantially flat installation surface, with the shaft portion facing upward in advance, the first bolt is located at a position close to the sun, and the second bolt is located at a position distant from the sun, with a predetermined distance from each other. The first elastic spacer having an insertion hole is first fitted into the shaft portions of the first and second bolts, and then the installation surface is attached with the first elastic spacer.
While mounting the solar cell module according to 2, 3, or 5, the bolt insertion hole of the first fixing member is provided on the shaft portion of the first bolt, and the second bolt is provided on the shaft portion of the second bolt. The bolt insertion holes of the fixing member are respectively fitted, and further the second elastic spacer having the insertion holes is fitted, and finally,
A nut is screwed onto a shaft portion of the first and second bolts, and the first and second fixing members are tightened by the nut and the first and second bolts. Item 7. A method for mounting the solar cell module according to item 7.
