  In the present embodiment, since the solar cell panels 8 are stacked horizontally, useless space is eliminated, the number of solar cell panels 8 that can be accommodated per unit volume increases, and the number of solar cell panels 8 is changed. However, it is not necessary to change the interval between the first wall surface plate material 21 and the second wall surface plate material 22 and the interval between the third wall surface plate material 23 and the fourth wall surface plate material 24. By surrounding the four surrounding surfaces of the stacked solar cell panels 8 with four plates, the lateral displacement of the solar cell panels 8 can be effectively prevented.

  By fastening the first fastening band 51 and the second fastening band 52, the first side wall plate material 21 and the second wall surface plate material 22 are connected to the long side surface 82 d that is the long side surface of the solar cell panel 8. Hold from both sides. Here, when the 1st wall surface board material 21 and the 2nd wall surface board material 22 hold | maintain the side surface by the side of the long side of the solar cell panel 8, compared with the case where the side surface by the side of a short side is hold | maintained reliably Can be held. Further, the force exerted on the solar cell panel 8 by the first wall surface plate material 21 and the second wall surface plate material 22 by tightening the first tightening band 51 and the second tightening band 52 acts in the short side direction of the solar cell panel 8. The bending deformation of the solar cell panel 8 is prevented compared to the case where this force acts in the long side direction of the solar cell panel 8. Further, the third wall surface plate material 23 and the fourth wall surface plate material 24 sandwich the first wall surface plate material 21 and the second wall surface plate material 22 therebetween. Therefore, when the width of the first wall surface plate material 21 and the second wall surface plate material 22 is larger than the length of the long side of the solar cell panel 8, even when the first tightening band 51 and the third tightening band 53 are tightened. The third wall surface plate member 23 and the fourth wall surface plate member 24 are prevented from exerting a force to bend and deform the solar cell panel 8 in the long side direction of the solar cell panel 8.

  When the solar battery panel packing box shown in FIG. 11 is loaded into a truck or container, the fork 68 of the forklift is inserted below the pallet bottom surface 1b in the direction (X direction) indicated by the arrow in the figure to lift the pallet 1. At this time, when the tip of the fork 68 does not reach the innermost second plate member 12, the tip of the fork 68 pushes up the third plate member 13 upward. In the pallet 1, a sufficient space is secured between the solar cell panel main body 81 and the third plate material 13 by the base 16, so that the third plate material 13 pushed up at the tip of the fork 68 moves the solar cell panel main body 81. It is prevented from being damaged.

  If sufficient care is taken not to push up the pallet bottom surface 1b with the fork 68, the solar cell panel 8 may be placed on the pallet top surface 1a without providing the base 16 on the pallet 1.

  Moreover, the packaging box of the solar cell panel shown in FIG. 11 can be stacked in two upper and lower stages. Here, since the top plate 3 is supported by the wall 2, it is possible to prevent the weight of the upper packaging box from acting on the solar cell panel 8 in the lower packaging box. Further, by securing a space between the upper surface plate 3 and the uppermost solar cell panel 8 (or the corrugated board 56 placed thereon), the upper surface plate 3 that is bent and deformed by a load may damage the solar cell panel 8. Is prevented. Stacking the packaging boxes in two upper and lower levels reduces the area for transportation and storage.

  Furthermore, in the solar cell panel packaging box shown in FIG. 11, the outer dimensions are only slightly larger than the dimensions of the stacked solar cell panels, which is advantageous for loading into a standard container. Whether or not a large number of packing boxes can be stacked in a standard container depends on a slight difference in the outer dimensions of the packing box, so the outer dimensions of the packing box should be as small as possible.
