Thereafter, the subunit 10 is moved to the left side, and the left end of the support rail 12 of the subunit 10 comes into contact with the positioning member 35 (see FIGS. 18A and 20).

  Since the subunits 10 are moved slightly during positioning and the ends of the support rails 12 of the subunits 10 adjacent to each other do not contact each other, it is possible to prevent the solar cell module bodies 11 from directly contacting each other. Can be prevented from being damaged by impact.

  Further, the side plate 25 b of the receiving portion 25 has a function of guiding the support rail 12 of each subunit 10. The sub unit 10 is supported at the time of positioning of the solar cell module because both the installation end portions 12d and 12d of the support rail 12 are only supported between the gantry 20 and 20 (receiving portions 25 and 25) on both sides. There is an advantage that the subunit 10 can be easily slid from the mounts 20 and 20 while the rail 12 is guided to the receiving portion 25.

  Further, the side plate 25 b of the receiving portion 25 has a function of guiding the support rail 12 of each subunit 10.

  In the same manner, after a predetermined number of subunits 10 are sequentially placed between the receiving portions 25, 25, they are brought into contact with the rear end of the support rail 12 of the subunit 10 previously positioned.

  Next, the fixture 24 is placed from the back side on the installation end portions 12d and 12d of the support rails 12 and 12 adjacent to each other in the left-right direction X placed and abutted on the placement plate 25a of the receiving portion 25. The placing operation can be performed as follows. In addition, since the positioning member 35 is attached to the receiving part 25, it removes from the receiving part 25 so that the fixing tool 24 may not be disturbed.

  That is, in the vicinity of the mounting end portion 12d of the one support rail 12 mounted on the mounting plate 25a of the receiving portion 25, the opening 12e is surrounded by the folded reinforcing portions 12c and 12c in the support rail 12 and opens downward. Then, the fixing tool 24 is inserted into the opening 12e by being inclined or rotated by 90 ° obliquely in a state along the longitudinal direction (left-right direction X) of the support rail 12. Further, the fixture 24 inserted from the opening 12 e is returned to the original substantially horizontal posture in the support rail 12 and then moved in the left-right direction X to be positioned on the receiving portion 25.

  Further, the through holes 24f of the fixture 24 are fitted from above to the screw portions S1a of the male screw S1 that are screwed into the female screw holes 25e of the receiving portion 25 and project upward, whereby each side plate 24d, 24d is placed on the inner surfaces of the folded reinforcing portions 12c, 12c of the installation ends 12d, 12d of the support rails 12, 12.

  Since the positions of the two female screw holes 24g, 24g of the fixture 24 and the two through holes 25h, 25h of the receiving portion 25 substantially coincide with each other, the screw portions S2a of the two male screws S2, S2 from the lower side of the receiving portion 25 are provided. S2a is passed through the two through holes 25h and 25h of the receiving portion 25 and is screwed into the two female screw holes 24g and 24g of the fixture 24, respectively. Thereby, the installation end portions 12d and 12d of the support rails 12 and 12 can be fixed to the receiving portion 25, that is, the vertical rail 23 (see FIG. 18A).

  Note that the end position where the subunit 10 does not exist next to the support rail 12 in the left-right direction X (the receiving portion 25 fixed to the bases 20, 20 at the left and right ends) is the installation end 11 d at the end position of the support rail 12. Only the receiving part 25 is mounted and the fixture 24 is attached.

  Moreover, in the said embodiment, after mounting the subunit 10 in the receiving part 25, the case where it fixes with the fixing tool 24 was illustrated, However, after positioning each subunit 10 (it mounts the next subunit 10) Before, it is also possible to fix each subunit 10 with a fixture 24. In such a case, a fixing tool 24 that can fix each subunit 10 individually is adopted.

  Then, after the placement work of the subunits 10 in the upper stage portion is completed (see FIG. 21), the placement work of the subunits 10 in the lower stage portion is performed in the same manner as described above (see FIG. 22).

  As described above, the solar cell module installation method according to the present embodiment makes it possible to easily and quickly position the plurality of subunits 10 at predetermined positions on the gantry 20. It is possible to easily and quickly perform the construction work of the photovoltaic power generation system in which 10) is arranged.

  23 to 25 show another embodiment of the receiving portion 25. FIG. 23 is a schematic cross-sectional view showing a state in which the receiving portion 25 is installed on the gantry 20, and FIG. 24 is a schematic perspective view of the state in which the receiving portion is fixed to the vertical rail as viewed obliquely from below. FIG. 25 is a schematic cross-sectional view showing a state where the subunit 10 is fixed to the receiving portion 25.

  In the present embodiment, the positioning member 40 is fixed to the receiving portion 25. In other words, the positioning member 40 is formed in an inverted U shape from a pair of leg portions 40a and 40a fixed and erected on the inner surface of the side plate 25b of the receiving portion 25 and a connecting portion 40b connected to both the leg portions 40a and 40a. It is configured. As shown in FIG. 25, the connecting portion 40b is configured such that the upper end of the support rail 12 (in the vicinity of the main plate 12a) abuts. In the receiving part 25 and the subunit 10 of the present embodiment, the same members as those of the receiving part 25 of the present embodiment are denoted by the same reference numerals, and description thereof is omitted.

  In the present embodiment, the support rail 12 of the subunit 10 is positioned by the positioning member 35 of each receiving portion 25. Thereafter, the same operation as in the above embodiment is performed, and the subunit 10 is fixed to the receiving portion 25 by the fixture 24 (see FIG. 25).

  Since the positioning member 40 according to the present embodiment is configured in an inverted U shape and abuts on the upper end of the support rail 12, when the fixture 24 is attached, a mounting space for the fixture 24 can be secured, and positioning is performed. The member 40 hardly gets in the way. As a result, in this embodiment, the operation of removing the positioning member 40 from the receiving portion 25 is not necessary.

  In addition, the solar cell module may be installed in a plurality of or all of the subunits 10 (solar cell modules) other than performing the placement operation of the subunits 10 in the lower part after the placement work of the subunits 10 in the upper part is completed. ) Is positioned on the gantry 20, and the solar cell module 10 can be fixed by a fixing portion.

  Further, the solar cell module can be installed by positioning the solar cell module 10 on the gantry 20 and fixing the solar cell module 10 to the gantry 20, and then fixing another solar cell module 10 to an arbitrary gantry 20. . Such a solar cell module installation method has an advantage that each solar cell module can be reliably fixed at a predetermined position because the positioned solar cell modules are individually fixed.
