PROBLEM TO BE SOLVED: To reduce the number of parts and to shorten the mounting time by a method wherein a fixing piece extending from the frame of a solar cell unit is fixed at a roof structural material by a bolt and the upper part of the bolt is covered with a cover piece protruding from each frame. SOLUTION: A fixing piece protruding from a frame 10 of each unit is directly fixed by a bolt 11, the frame 10 is mounted only through one work process, and the number of parts may be reduced. Further, the fixing part of the frame 10 is covered with a cover piece protruded from the frame 10, penetration of rainwater from above to the bolt hole 19 side for mounting is prevented from occurring, and the waterproofness is improved. In this case, the bolt 11 is inserted through a bolt hole 19 of a press fitment side piece for fixing the frame and further inserted through a slit 21 in the bolt holes 19 formed in a sheathing roof board 6 and a main house 4 to arrange the frame 10. This constitution forms a unit where a solar cell module 28 is premounted on the frame 10, and saves a labor required for site operation. |
