  The flange portion 7 is provided on the back surface 10b side of the solar cell panel 10 and at a position farther from the solar cell panel 10 than the holding lower piece 6, and is provided to face the outer peripheral portion of the back surface 10b of the solar cell panel 10. It is done. The flange portion 7 is substantially parallel to the back surface 10 b of the solar cell panel 10.

  FIG. 4A is a partial enlarged cross-sectional view in which a portion B shown in FIG. 3 is enlarged. The connection part 8 connects the flange part 7 with respect to the wall part 4 so that rotation is possible. The connecting portion 8 includes a wall portion side connecting portion 15 formed on the wall portion 4 and a flange side connecting portion 16 formed on the flange portion 7.

  The wall part side connection part 15 has the wall part side 1st semicircle part 17 which protrudes toward the inner side (solar cell panel 10 side) of the holding frame 20 from the wall part 4. As shown in FIG. As shown in FIG. 4A, the cross-sectional shape of the wall-side first semicircular portion 17 has a semicircular shape that is convex upward. A plate-like wall-side plate-like portion 18 linearly extending from the tip of the wall-side first semicircular portion 17 toward the center of the semicircular shape exhibited by the wall-side first semicircular portion 17 is formed. . And from the front-end | tip of the wall part side plate-shaped part 18, the wall part side 2nd semicircle part 19 which exhibits the semicircle shape which cross-sectional shape becomes convex toward the outer side of the holding frame 20 is formed.

  Next, although the flange side connection part 16 is demonstrated, the direction used in this description has shown the direction in the state in which the flange part 7 is parallel to the back surface 10b of the solar cell panel 10. FIG. The flange-side connecting portion 16 has a flange-side semicircular portion 23 having a semicircular shape whose cross-sectional shape is convex toward the outside of the holding frame 20.

  The outer diameter of the flange-side semicircle portion 23 is slightly smaller than the inner diameter of the wall-side first semicircle portion 17, and the flange-side semicircle portion 23 is accommodated inside the wall-side first semicircle portion 17. In a state where the flange-side semicircle portion 23 is accommodated inside the wall-side first semicircle portion 17, the center of the wall-side first semicircle portion 17 and the center of the flange-side semicircle portion 23 substantially coincide with each other. Moreover, the outer diameter of the wall side second semicircular portion 19 is slightly smaller than the inner diameter of the flange side semicircular portion 23, and the wall side second semicircular portion 19 is accommodated inside the flange side semicircular portion 23. The

  From one end above the flange-side semicircular portion 23, a flange-side plate-like portion 24 is formed that extends linearly toward the center of the semicircular shape exhibited by the flange-side semicircular portion 23. A connecting portion 25 that connects the flange portion 7 and the flange-side semicircle portion 23 is formed at the other end above the flange-side semicircle portion 23.

  In the present embodiment, a part of the connecting portion 25 is formed into a cylindrical shape including the flange portion 7 so as to ensure the strength of the holding frame 20. Moreover, a part of wall which comprises cylindrical shape among the connection parts 25 becomes the taper wall 25a which approaches inside as it goes below. In addition, you may comprise the connection part 25 so that the flange part 7 and the flange side semicircle part 23 may be connected only with a plate-shaped member.

  By configuring the connecting portion 8 as described above, the flange portion 7 is formed in the direction indicated by the arrow X with the center of the wall side first semicircular portion 17 (the center of the flange side semicircular portion 23) as the rotation center. It can be rotated. Further, in the state shown in FIG. 4A, the tip of the wall-side second semicircular portion 19 and the flange-side plate-like portion 24 are in contact with each other, and the other end of the flange-side semicircular portion 23 and the wall-side plate. The contact with the shape portion 18 restricts the flange portion 7 from rotating in the direction opposite to the direction indicated by the arrow X.

  FIG. 4-2 is a partial enlarged cross-sectional view in which the portion B shown in FIG. 3 is enlarged, and shows a state where the flange portion is perpendicular to the back surface of the solar cell module. By rotating the flange portion 7 in the direction indicated by the arrow X from the state shown in FIG. 4A, the flange portion 7 is brought into a state perpendicular to the back surface 10b of the solar cell panel 10 as shown in FIG. Can do. Thus, by rotating the flange portion 7, the flange portion 7 can be moved to the outside of the wall portion 4. When the flange portion 7 is rotated, the taper wall 25a spreads outward as it goes downward.

  In the state shown in FIG. 4B, the flange portion plate-like portion 18 and the flange-side plate-like portion 24 are in contact with each other, and the lower end of the wall portion 4 and the connecting portion 25 are in contact with each other. 7 is further restricted from rotating in the direction indicated by arrow X. Further, since the rotation axis C of the flange portion 7 is provided on the inner side than the wall portion 4, it is not necessary to provide a rotation mechanism such as the wall portion side connecting portion 15 and the flange side connecting portion 16 on the outer side than the wall portion 4. The part which protrudes from the outer peripheral part of the holding frame 20 can be eliminated.

  FIG. 5 is a diagram illustrating a state in which the solar cell modules 100 are stacked. As shown in FIG. 5, when laminating the solar cell module 100, the flange portion 7 is moved to the outside of the wall portion 4. By moving the flange portion 7 to the outside of the wall portion 4, the flange portion 7 is more than the distance P (see also FIG. 3) between the flange portions 7 when the flange portion 7 is inside the wall portion 4. The distance Q between the flange portions 7 in the state of being outside the portion 4 is larger. Furthermore, since the flange portion 7 is outside the wall portion 4, the distance Q becomes larger than the width R of the outer shape at the upper end of the holding frame 20. That is, the opening area of the lower end of the holding frame 20 is larger than the area of the upper end surface of the solar cell module 100.

  Therefore, when the solar cell module 100 is stacked, the upper end of the lower solar cell module 100 can be inserted between the flange portions 7 of the upper solar cell module 100, and the stacking height can be suppressed. it can. Thereby, more solar cell modules 100 can be loaded in a limited height.

  Further, the flange portion 7 of the upper solar cell module 100 and the holding frame 20 of the lower solar cell module 100 are fitted to each other, so that the stacked solar cell modules 100 are hardly displaced and the transportability is improved. Can be achieved. Moreover, since the upper end of the solar cell module 100 is guided to an appropriate position by the taper wall 25a that expands downward, alignment when the solar cell modules 100 are stacked is facilitated.

  FIG. 6 is a diagram illustrating an installation example of the solar cell module 100. The solar cell module 100 is installed on the rail member 201. The upper end portion of the solar cell module 100 is pressed by the engaging member 202. In this state, the solar cell module 100 is fixed by coupling the engaging member 202 and the rail member 201 with the bolt member 203.

  As described above, since the protruding portion is not provided on the outer peripheral portion of the holding frame 20, the module pitch and the module height can be made the same as when the holding frame without the protruding portion is used. The external dimension of itself can be made the same as the conventional one. Therefore, the engagement member 202 for fixing the solar cell module 100 is not prepared as a dedicated product, and can be shared with the conventional product.

  FIG. 7 is a diagram illustrating another installation example of the solar cell module. As shown in FIG. 7, if a hole 7 a through which a bolt 26 or the like can be penetrated is formed in the flange portion 7, the flange portion 7 is attached to the gantry 300 having a fixing surface perpendicular to the light receiving surface 10 a of the solar cell panel 10. It is also possible to fix via. In this case, since the extending direction of the bolts 26 is parallel to the back surface 10b of the solar cell panel 10, even if a relatively long bolt 26 is used, it does not interfere with the solar cell panel 10. Therefore, when the solar cell module 100 is installed, it is possible to suppress the occurrence of problems such as the solar cell panel 10 being damaged by the bolts 26.

  As mentioned above, the solar cell module concerning this invention is useful for a solar cell module provided with the holding frame holding the outer periphery of a solar cell panel.
