Here, the fixing portion 41 and the pressing portion 42 are connected to each other by the side wall 44 so that the bottom surfaces of the fixing portion 41 and the pressing portion 42 are parallel to each other, and the flange Me of the lower frame Mc of the solar cell module M is pressed by the pressing portion 42. The tip of the flange Me is in contact with the end surface 41a of the fixed portion 41. Further, by increasing the height of the side wall 44, the flange Me can be pressed more firmly by the pressing portion 42.

  The positioning hook 43 is inserted into a positioning hook hole 43 a formed in the vertical rail 2. Since the positioning hook 43 is inserted into the positioning hook hole 43a, the locking tool 40 does not slide down from the vertical rail 2, and the mounting work of the locking tool 40 becomes easy. Further, the positioning hook 43 also functions as a detent portion that prevents the locking tool 40 from rotating.

In addition, since the end face 41a of the fixing portion 41 is in contact with the front end of the flange Me at right angles, the locking tool 40 has good positioning accuracy of the solar cell module M. Therefore, it is possible to use this locking tool 40 instead of the locking portion 10 shown in FIG. Thereby, the cut-and-raised piece 13 which becomes a protrusion is eliminated from the upper flange 2b of the vertical beam 2, and the vertical beam 2 can be easily packed, and there is no damage during transportation.

  The solar cell module installation stand and fixing method of the present invention are useful as an installation stand and fixing method for installing the solar cell module with an inclination angle.
