FIG. 1 is a perspective view showing a support structure of a solar cell module according to an embodiment of the present invention, and FIG. 2 is an enlarged view of a main part of the support structure.

  As will be described below, the solar cell module support structure is constructed so as to support a plurality of solar cell modules M at a predetermined light receiving angle with respect to a horizontal plane. A concrete block 10 is installed on the ground on which the solar cell module is disposed, corresponding to the support location of each solar cell module. In this embodiment, the left and right edge portions of the solar cell module are supported at four locations, and the concrete block 10b on the heel side in FIG. 1 is oriented so that the solar cell module is directed to a light receiving angle at which sunlight is efficiently received. Is higher than the concrete block 10a on the front side.

  Hereinafter, for the sake of explanation, the side with the low concrete block 10a (front side in FIG. 1) is referred to as the front, and the side with the high concrete block 10b (back side in FIG. 1) is referred to as the rear. Further, since the solar cell module is tilted back and forth due to this height difference, this direction is referred to as a tilt direction, and the left-right direction of the solar cell module perpendicular to this direction is referred to as a contour direction. A solar cell module is a solar cell (minimum unit of components of a solar cell used for photovoltaic power generation) or a solar cell sub-module (minimum unit of a group of solar cells formed simultaneously on one substrate that cannot be divided). It is the smallest unit of power generation unit enclosed in an envelope for environmental resistance and having a specified output.

  A mounting bracket 20 is installed on each concrete block 10. The mounting bracket 20 includes a holding plate 30 standing on the concrete block M and a support piece 40 held on the holding plate.

  As shown in FIG. 3, the holding plate 30 is formed by bending a flat steel plate, and an inclined direction plate 31 (first direction plate) extending in the inclined direction (first direction) of the solar cell module; A contour plate 32 (second direction plate) is provided which is bent from the inclined direction plate and extends along the contour direction (second direction). The lower portions of the plates 31 and 32 are bent outward to form leg portions 311 and 321. Slits 312 and 322 extending in the horizontal direction are formed in the upper portions of the inclined direction plate 31 and the contour direction plate 32, respectively. Fixing holes 313 and 323 are formed in the leg portions 311 and 312, respectively, and anchor bolts 57 erected on the concrete block 10 are passed through these holes 312 and 322 to fasten the nut 58. A holding plate 30 is fixed to the concrete block 10. Alternatively, fixing plates passed through the holes 313 and 323 may be screwed into the concrete block 10 to fix the holding plate 30 to the concrete block 10.

  The support piece 40 is formed by bending a long and narrow steel plate, and an inclined direction piece 41 (first direction piece) in which the lower portion 411 is supported by a contour plate and extends in the vertical direction and the upper portion 412 extends at the inclination angle; The lower portion 421 is supported by the inclined direction plate and extends in the vertical direction, and the upper portion 422 is distinguished from the contour piece (second direction piece) 42 extending in the contour direction at the tilt angle.

  These support pieces 40 are further differentiated in this embodiment. That is, as shown in FIGS. 4 to 7, the inclined direction piece 41 forms an obtuse angle with respect to the lower direction 411 and the inclined direction piece 41 a in which the upper portion 412 extends at the inclined angle on the side forming an acute angle with the lower portion 411. On the side, the upper part 412 is distinguished from an inclination direction piece 41b extending at the inclination angle. Further, the contour piece 42 includes a contour piece 42a in which an upper portion 422 extending rightward with respect to the lower portion 421 is inclined at the inclination angle, and an upper portion 422 extending leftward with respect to the lower portion 421 is inclined. And the contour direction piece 42b which is inclined.

  These four types of support pieces are arranged with respect to the solar cell module M as follows. That is, the concrete blocks 10 are arranged one by one in the front-rear direction across the two solar cell modules around the boundary between the solar cell modules M adjacent to the left and right. One mounting bracket 20 is placed on each concrete block 10. Therefore, the concrete block 10 and the mounting bracket 20 are arranged at four positions on the edge of one solar cell module M, and the concrete block 10 and the mounting bracket 20 are shared by the solar cell modules adjacent to the left and right. It is in shape.

If this is seen about the solar cell module M0 of the center of FIG. 1, the attachment metal fitting 20 is arrange | positioned as follows.
Mounting bracket 20a located on the right front: [Contour direction plate 32] + [Inclined direction piece 41a in which the upper portion 412 forms an acute angle with respect to the lower portion 411]
Mounting bracket 20b located at the left rear: [Contour direction plate 32] + [Inclined direction piece 41b in which the upper portion 412 forms an obtuse angle with respect to the lower portion 411]
Mounting bracket 20c located on the left front: [inclined direction plate 31] + [contour height piece 42a in which the upper part 422 extends rightward with respect to the lower part 421]
Mounting bracket 20d located at the right rear: [inclined direction plate 31] + [contour direction piece 42b in which the upper part 422 extends leftward with respect to the lower part 421]

  When the ground is deformed due to uneven subsidence or the like, the relative positions of the four concrete blocks 10 change accordingly, and as a result, distortion may occur in various directions. On the other hand, as shown above, four different support forms coexist for one solar cell module M, so that various absorption performances can be exhibited, and high support stability. can get. In addition, in the four types of support forms, the holding plate 30 has a common shape and the installation direction may be changed, so that the manufacturing cost of the mounting bracket 20 is reduced.

These mounting brackets 20a to 20d have the following structure and arrangement in relation to the solar cell modules M1 and M2 located on the right and left of the solar cell module M0 in the center of FIG.
For the solar cell module M1 on the right side,
Mounting bracket 20a: [Inclined direction plate 31] + [Contour height piece 42a in which the upper portion 422 extends to the right with respect to the lower portion 421]
Mounting bracket 20d: [Contour direction plate 32] + [Inclined direction piece 41b in which the upper portion 412 forms an obtuse angle with respect to the lower portion 411]
For the solar cell module M2 on the left side,
Mounting bracket 20b: [Inclined direction plate 31] + [Contour height piece 42b in which the upper portion 422 extends leftward with respect to the lower portion 421]
Mounting bracket 20c: [Contour direction plate 32] + [Inclined direction piece 41a in which the upper portion 412 forms an acute angle with respect to the lower portion 411]

  In this embodiment, the solar cell module M has a size of about 1 m in the contour direction and about 1.5 m in the inclination direction, and the holding plate 30 and the support piece 40 each have a height of about 10 cm. The solar cell module M supported by this support structure is inclined at about 15 degrees with respect to the waterside surface.

  By making the structure and arrangement of the mounting brackets in this way, the mounting brackets 20a and 20c positioned in front of one solar cell module M are bent from the contour direction plate 32 to the front in the inclined direction plate 31, and to the rear. The mounting brackets 20b and 20d located are in a state in which the inclined direction plate 31 is bent backward from the contour direction plate 32. Thereby, when attaching to the solar cell modules M arranged in the left-right direction from the front and the rear, the inclined direction plate 31 is not positioned on the heel side of the contour plate 32, and the operation is performed. It is easy to do.

  Note that the mounting bracket 20 located at the left and right ends of the plurality of solar cell modules M arranged only needs to include only one support piece 40. For example, the mounting brackets 20e and 20f that support the left edge of the solar cell module M2 shown at the left end of FIG. 1 each include only the inclined direction piece 41b and the contour direction piece 42a. Although FIG. 1 shows only one row of solar cell modules M on the left and right, in many cases, the solar cell modules M arranged in the left and right directions are also installed in the same manner on the front or rear side.

  Each of the support pieces 41 and 42 has a plurality of (in this example, five) holes 413 formed in the lower portions 411 and 421, and slits 414 and 424 extending in the extending direction (longitudinal direction) of the upper portions 412 and 422. Is formed.

  As shown in detail in FIG. 8 and FIG. 9, the bolt 51 is passed through one of the slits 312 and 322 of the holding plate 30 and the holes 413 and 423 of the support pieces 41 and 42, and the nut 52 is fastened. 41 and 42 are fixed to the holding plate 30. A flat washer 53 is interposed between these members to be fastened as necessary. A spring washer 54 is interposed between the holding plate 30 and the support piece 40 and between the bolt head of the bolt 51 and the holding plate 30. Then, the fastening torque is adjusted at the time of fastening the bolt, and the bolt 51 is fastened so that it can slide along the slits 312 and 322 with the support pieces 41 and 42 by an external force of a predetermined value or more. The magnitude of the external force that causes sliding is determined according to the assumed amount of ground deformation, the size and weight of the solar cell module, etc., and even if the ground deforms, the solar cell absorbs part or all of it. The module is protected from damage.

  FIG. 9 shows a mounting structure between the mounting bracket 20a and the solar cell module M. As shown in the figure, the solar cell module M has a structure in which a solar cell main body 88 is supported by a frame 80. The frame 80 surrounds the four circumferences of the solar cell body 88 and includes an upper frame 81, an outer frame 82, a step portion 83 projecting inward from the outer frame 82, a lower frame 84, and a filler 85.

  The frame 80 is bolted to the mounting bracket 20. In this regard, FIG. 9 shows an example of the mounting bracket 20a. The bolt 51 is passed through the hole formed in the lower frame 84 of the frame 80 and the slit 424 of the upper support piece 422, and the nut 52 is fastened. Also in this case, a flat washer 53 is interposed between these members to be fastened as necessary. Further, spring washers 54 are interposed between the bolt head of the bolt 51 and the lower frame 84, and between the lower frame 84 and the support piece 40. Then, the fastening torque is adjusted at the time of fastening the bolt, and the bolt 51 is fastened so that it can slide along the slit 424 with the lower frame 84 by an external force of a predetermined value or more.

  The support structure of the solar cell module constructed as described above operates as follows. When ground distortion occurs due to uneven settlement at the installation location of the solar cell module M, the relative positions of the four concrete blocks 10 change. FIG. 10 shows an example of the state in which the bolt 51 is slid along the slit by the external force in this way. Even when the ground fluctuation causes the settlement of one concrete block 10, the solar cell module M is distorted in three dimensions, so that the support location by the mounting bracket 20 is not only in the vertical direction but also in the horizontal direction and the torsional direction. The displacement also reaches the mounting bracket 20 on the other concrete block 10 and acts as an external force. On the other hand, when the external force increases beyond a predetermined value, the mounting bracket 20 has the bolt 51 along the slit between the holding plate 30 and the support piece 40 and between the support piece 40 and the solar cell module M. Slide. Part or all of the external force is absorbed by the sliding, and the solar cell module is prevented from receiving a large external force from the support portion, and stable support is maintained.

  Moreover, since stable support is maintained in this way, it is not necessary to monitor the support state after installation of the solar cell module, or it can be reduced to a very low frequency. This is extremely advantageous in that the necessity of maintenance can be greatly reduced when an extremely large number of solar cell modules are installed as in a large power generation system that supplies electric power to many households.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this, A various change is possible unless it deviates from the meaning. For example, when fixing the support pieces 41 and 42 to the holding plate 30, any one or a plurality of locations between the holding plate 30, the support piece 40, the bolt head of the bolt 51 that fastens them, and the nut 52. A spring washer 54 can be interposed between the two. Further, when the solar cell module M is fixed to the support piece 40, any one or a plurality of locations between the solar cell module M, the support piece 40, the bolt head of the bolt 51 for fastening them, and the nut 52. A spring washer 54 can be interposed between the two.

  In the above-described embodiment, the support piece 40 is classified into the inclined direction piece 41 and the contour direction piece 42, the inclined direction piece 41 is distinguished into those having an acute angle and an obtuse angle, and the contour direction piece 42 is The extension direction is distinguished from right and left. As a result, various strain absorption performances can be exhibited as described above, but if the necessity is low, one or both of the inclined direction piece 41 and the contour direction piece 42 can be used as any one of the specifications. Good. Furthermore, when the degree of necessity for the diversity of strain absorption performance is low, only one of the inclination direction piece 41 and the contour direction piece 42 may be used.

  In addition, the number of mounting brackets that support one solar cell module M is usually four in terms of the stability of the support and the efficiency of work, but this is three, or five or more. You can also The place where the solar cell module is supported by the mounting bracket may be the upper and lower edges, or a combination thereof, in addition to the left and right edges.
