  Hereinafter, a solar cell device PA according to an embodiment of the present invention will be described in detail with reference to the drawings. In addition, about the member of the same name which comprises the solar cell apparatus PA, the same code | symbol shall be attached | subjected and the overlapping description is abbreviate | omitted.

<< First Embodiment >>
As shown in FIG. 1, the solar cell device PA includes a solar cell module 1 corresponding to a structure and a structure mount 2 that stands on the installation surface P. The structure mount 2 supports the solar cell module 1 on the installation surface P. The structure mount 2 includes a foundation 21, a tubular member 22, a beam member 23, and a clamp member 24. The beam member 23 includes a first beam member 23A and a second beam member 23B.

  In the following description, it is assumed that the installation surface P on which the solar cell device PA is installed is a horizontal ground. A coordinate axis parallel to the installation surface P and parallel to the second beam member 23B constituting the solar cell device PA is defined as an X axis, and a direction along the X axis is defined as an X direction. A coordinate axis parallel to the installation surface P and perpendicular to the X axis is defined as a Y axis, and a direction along the Y axis is defined as a Y direction. A coordinate axis parallel to the vertical direction is taken as a Z axis, and a direction along the Z axis is taken as a Z direction. In the following description, the direction against gravity is referred to as “up”, and the direction following gravity is referred to as “down”.

  Next, each member of the solar cell device PA will be described.

<Basic>
The foundation 21 has a function as a foundation of the solar cell device PA. As such a foundation 21, it is good to use the screw pile which is a kind of friction pile. The material of such a screw pile should just be stainless steel, for example. Moreover, a screw pile has a spiral wing-like part in the outer periphery of the pile body of a circular section, for example. Thereby, circumferential friction and drawing resistance are improved. By using such a friction pile for the foundation 21, construction and removal work is easy. Therefore, such a foundation 21 is easy to use on land (for example, farmland) where conditions for permitting temporary diversion are present. Further, the screw pile has an increased pulling resistance when a wind pressure in the blowing direction is applied to the solar cell device PA by the wing-shaped portion. As a result, the strength of the solar cell device PA can be increased.

<Tubular member>
The tubular member 22 is a columnar body arranged on the installation surface P such that the longitudinal direction is perpendicular to the installation surface P. As shown in FIG. 1, a plurality of tubular members 22 are erected on a foundation 21 to support a beam member 23 described later. The tubular member 22 has a first end surface 22a located on the solar cell module 1 side and a second end surface 22b located on the installation surface P side. The first end surface 22 a is located below the solar cell module 1 and is disposed to face the back surface of the solar cell module 1. For example, the tubular member 22 is arranged with an interval of about 5 m so that an agricultural machine can be used below the solar cell module 1. At this time, the height to the upper end of the tubular member 22 is preferably 3 m or more so that the beam member 23 can be disposed at a height of 3 m or more. The tubular member 22 is a rod-shaped steel pipe having an outer diameter of 40 to 80 mm and a thickness of 2 to 6 mm subjected to hot dip galvanization. In addition, after installation of the solar cell device PA, the tubular member 22 may be coated with a corrosion-resistant paint on a portion on the installation surface P side to enhance the corrosion resistance. Thereby, the corrosion etc. by adhesion of the organic substance contained in soil can be reduced.

<Beam members>
The solar cell module 1 is disposed on the beam member 23. In other words, the beam member 23 supports the solar cell module 1 directly or indirectly. The beam member 23 includes a first beam member 23A and a second beam member 23B.

  The first beam member 23A is a long member that is passed over the tubular members 22 arranged in the Y direction with the Y direction as the longitudinal direction. The first beam member 23 </ b> A has a first plate-like portion 23 </ b> Aa that is located below the solar cell module 1 and covers the upper side of the first end surface 22 a of the tubular member 22. Further, the first beam member 23A has a second plate-like portion 23Ab that is connected to the first plate-like portion 23Aa and is fixed to the fixture 24d of the clamp member 24. Specifically, as shown in FIG. 2, the first beam member 23A is a member having an L-shaped cross section in which the first plate-like portion 23Aa and the second plate-like portion 23Ab are connected to be orthogonal to each other. . The first beam member 23A may not have a structure in which the first plate-like portion 23Aa and the second plate-like portion 23Ab are orthogonal to each other. For example, a structure in which the first plate-like portion 23Aa and the second plate-like portion 23Ab intersect at an obtuse angle or an acute angle may be employed. Further, the first plate-like portion 23Aa and the second plate-like portion 23Ab may not be connected at the end portions. For example, the structure where the edge part of 2nd plate-shaped part 23Ab is connected to the center part of 1st plate-shaped part 23Aa may be sufficient.

  The first plate-like portion 23Aa only needs to be positioned so as to cover the first end surfaces 22a of the plurality of tubular members 22. Note that the first plate-like portion 23Aa in the present embodiment is not limited to a flat plate shape as long as it can support a structure, and may be, for example, a partially curved shape. Furthermore, the surface on the solar cell module 1 side and the surface on the installation surface P side of the first plate-like portion 23Aa may be slightly inclined with respect to the XY plane.

  The second plate-like portion 23Ab is connected to a part of the first plate-like portion 23Aa (the end of the first plate-like portion 23Aa in FIG. 3) and extends toward the installation surface P. Further, the second plate-like portion 23Ab may have the same shape as the first plate-like portion 23Aa. The second plate-like portion 23Ab has a through hole 23Ac for inserting a fixture 24d of the clamp member 24 described later.

  The first beam member 23A can be formed by, for example, hot dip galvanizing on steel having an L-shaped cross section formed by extrusion molding. As another material, a steel plate whose surface is plated may be formed by bending.

<Second beam member>
The second beam member 23B is a long member that passes over the plurality of first beam members 23A arranged in the X direction with the X direction as the longitudinal direction. The plurality of second beam members 23B are disposed on the plurality of first beam members 23A at intervals so as to be orthogonal to the longitudinal direction of the first beam member 23A. More specifically, the second beam member 23B is fixed on the first plate-like portion 23Aa of the first beam member 23A by a U-shaped fixing member or the like. Moreover, the solar cell module 1 is arrange | positioned and supported on a pair of 2nd beam member 23B adjacent to a Y direction. Similarly to the tubular member 22, the second beam member 23B can be formed by hot dip galvanizing a steel pipe.

<Clamp member>
The clamp member 24 is a member for inserting and holding the end portion of the tubular member 22 on the first end surface 22a side. As shown in FIG. 3, the clamp member 24 has a main body portion 24a, a grip portion 24c connected to the main body portion 24a via a hinge portion 24b, and a fixture 24d.

  The hinge part 24b has a function of opening and closing while connecting the main body part 24a and the grip part 24c. The fixture 24d is a member having a shaft portion such as a bolt. The fixing tool 24d fixes the main body portion 24a and the grip portion 24c to the through hole 23Ac provided in the second plate-like portion 23Ab of the first beam member 23A, and between the main body portion 24a and the grip portion 24c. The tubular member 22 has a function of tightening and gripping.

  When the fixing member 24d is loosened, the clamp member 24 opens between the main body portion 24a and the grip portion 24c, and the tubular member 22 can be inserted. Accordingly, the clamp member 24 is fixed to the tubular member 22 by inserting the end portion on the first end face 22a side of the tubular member 22 into the hole portion surrounded by the main body portion 24a and the grip portion 24c. Further, the clamp member 24 can rotate in parallel with the surface of the second plate-like portion 23Ab around the shaft portion of the fixture 24d. As a result, the position of the clamp member 24 can be adjusted.

  The tubular member 22 is fastened and fixed between the main body portion 24a and the grip portion 24c by fastening the fixture 24d of the clamp member 24. The tubular member 22 is fixed to the first beam member 23A with the clamp member 24 facing in a predetermined direction. Since the clamp member 24 has the above-described structure, it has two functions of fixing to the first beam member 23A by the fixing tool 24d and fixing the tubular member 22, so that the fixing structure can be simplified. Such a clamp member 24 is formed of a steel material or the like subjected to hot dip galvanization.

  As shown in FIG. 2, the tubular member 22 is attached to a clamp member 24 attached to the second plate-like portion 23Ab of the first beam member 23A by a fixing tool 24d. Further, as viewed from above, the first end face 22a of the tubular member 22 is covered with the first plate-like portion 23Aa of the first beam member 23A. Moreover, you may make it the 1st end surface 22a of the tubular member 22 contact | connect the 1st plate-shaped part 23Aa. Thereby, rainwater etc. become difficult to enter into the tubular member 22, and corrosion of the tubular member 22 can be reduced. On the other hand, the first end surface 22a of the tubular member 22 may be separated from the first plate-like portion 23Aa.

<Solar cell module>
The solar cell module 1 has a solar cell panel 10 as shown in FIG. The solar cell panel 10 has a light receiving surface 10a (front surface) and a back surface 10b of the light receiving surface 10a. Moreover, the solar cell panel 10 is rectangular. Moreover, as shown in FIG. 1, the solar cell panel 10 is inclined and disposed on the structural frame 2.

  The solar cell panel 10 includes a translucent substrate 11, a plurality of solar cell elements 12 disposed at predetermined positions with respect to the translucent substrate 11 and electrically connected to each other, and the periphery of the solar cell elements 12. And a back surface protection member 14 are laminated.

  The solar cell element 12 has a function of converting incident light into electricity. Such a solar cell element 12 includes, for example, a semiconductor substrate made of single crystal silicon or polycrystalline silicon, and electrodes provided on the front surface (upper surface) and the back surface (lower surface) of the semiconductor substrate. The solar cell element 12 having a single crystal silicon substrate or a polycrystalline silicon substrate has, for example, a quadrangular shape in plan view. At this time, the size of one side of the solar cell element 12 is, for example, 100 to 200 mm.

  In addition, the kind in particular of the solar cell element 12 is not restrict | limited. In addition to the above, for example, a thin-film solar cell element in which the photoelectric conversion portion in the solar cell element is made of a material such as amorphous silicon, chalcopyrite such as CIGS, or CdTe may be employed. As the above-described thin-film solar cell element, for example, a glass substrate on which a photoelectric conversion layer made of amorphous silicon, CIGS, CdTe, or the like, a transparent electrode, and the like are appropriately stacked can be used. Such a thin-film solar cell element is obtained by patterning and integrating the photoelectric conversion layer and the transparent electrode on a glass substrate. Therefore, in the thin film solar cell element, the wiring material 16 that connects the plurality of photoelectric conversion layers can be eliminated. Furthermore, the solar cell element 12 may be of a type in which a thin film of amorphous silicon is formed on a single crystal or polycrystalline silicon substrate.

  The filler 13 is provided on both main surface sides of the solar cell element 12. Thereby, the filler 13 has a function of sealing the solar cell element 12. Examples of the filler 13 include thermosetting resins such as transparent ethylene vinyl acetylate copolymers.

  The back surface protection member 14 has a function of protecting the solar cell element 12 and the like from the back surface side. Such a back surface protection member 14 is bonded to the filler 13 located on the back surface side of the solar cell panel 10. As such a back surface protection member 14, for example, PVF (polyvinyl fluoride), PET (polyethylene terephthalate), PEN (polyethylene naphthalate), or a laminate obtained by appropriately selecting these can be used.

  In addition, the back surface protection member 14 is not restricted to the colored thing, You may use glass and a transparent resin material. By using the transparent back surface protection member 14, incident light between the adjacent solar cell elements 12 can be transmitted to the back surface 10 b side of the solar cell panel 10. Thereby, the incident light to places other than the solar cell element 12 can be transmitted to the installation surface P and used for growing crops.

  Further, a frame 15 is attached to the outer periphery of the solar cell panel 10. The frame 15 has a function of improving the load resistance of the solar cell module 1 and protecting it from impact. As such a frame 15, for example, a material obtained by extruding a metal such as an aluminum alloy can be used.

  Further, in the solar cell panel 10, adjacent solar cell elements 12 are electrically connected by a wiring material 16. Specifically, the wiring member 16 electrically connects an electrode located on the surface of one solar cell element 12 and an electrode located on the back surface of the other solar cell element 12. Thereby, the several solar cell element 12 is arranged so that it may be connected in series. Examples of such a wiring member 16 include a copper foil coated with solder.

In the structural mount 2 and the solar cell apparatus PA according to the present embodiment, the first beam member 23A first
Plate-like part 23Aa is arrange | positioned so that the upper side of the 1st end surface 22a of the tubular member 22 may be covered. Thereby, the clamp member 24 fixed to the tubular member 22 by thermal expansion / shrinkage is loosened, and the clamp member 24 moves to the installation surface P side together with the first beam member 23A, the second beam member 23B, and the solar cell module 1. However, since the first plate-like portion 23Aa contacts the first end surface 22a of the tubular member 22, the clamp member 24 is less likely to move than necessary. As a result, the first end surface 22a of the tubular member 22 is less likely to collide with the back surface 10b of the solar cell module 1. Therefore, in this embodiment, the output fall of the solar cell module 1 resulting from the crack of the solar cell element 12 by this collision, etc. can be reduced. Furthermore, in the present embodiment, the dropping off and deformation of the solar cell module 1 that can be caused by excessive deformation of the structural unit mount 2 can be reduced.

  Usually, when constructing the structural mount 2, it takes effort to lift both ends of the first beam member 23A at a time and connect the both ends to the tubular member 22 adjacent in the Y direction by the clamp member 24. In the present embodiment, since the fixture 24d has a shaft portion that passes through the through hole 23Ac of the first beam member 23A, the clamp member 24 can be attached to the first beam member 23A by loosely fastening the fixture 24d. it can. At this time, since the clamp member 24 is rotatable with respect to the first beam member 23A, the workability can be improved. Specifically, as shown in FIG. 5A, one end of the first beam member 23A is loosely tightened on the first end face 22a side of one tubular member 22 adjacent in the Y direction to loosen the first fixture 24d. The beam member 23 </ b> A is rotatable with respect to the tubular member 22 and connected by a clamp member 24. Next, as shown in FIG. 5B, the other end of the first beam member 23A is lifted from the installation surface P while rotating the clamp member 24 attached to one end of the first beam member 23A. Next, the clamp member 24 attached to the other end of the first beam member 23A is connected to a portion on the first end face 22a side to the other tubular member 22 adjacent in the Y direction. Next, the fixtures 24d of the clamp members 24 at both ends of the first beam member 23A are further tightened and tightened.

  As mentioned above, in this embodiment, since the edge part of the 1st beam member 23A can be lifted up one by one, it can construct by one worker and can improve workability.

  Furthermore, since the clamp member 24 is fixed by a fixing tool 24d having a shaft portion, the angle can be freely adjusted by loosening the fixing tool 24d. In addition, the clamp member 24 may be provided with a gap between the first plate-like portion 23Aa and the first end face 22a side of the tubular member 22, so that the tubular member 22 is strictly aligned in the Z direction. It is not necessary. Thereby, workability can be improved.

<< Second Embodiment >>
As shown in FIG. 6, the present embodiment is different from the first embodiment in that the first beam member 23A has a third plate-like portion 23Ad. Specifically, the first beam member 23A has a third plate-like portion 23Ad that is connected to the first plate-like portion 23Aa and extends downward so as to face the second plate-like portion 23Ab. Yes. Further, the second plate-like portion 23Ab and the third plate-like portion 23Ad are located so as to cover the side surface 22c of the end portion of the tubular member 22 on the first end surface 22a side. This makes it easier for the third plate-like portion 23Ad to block the blowing of rainwater into the tubular member 22 and to prevent the rainwater that has been blown from being stored. As a result, corrosion of the tubular member 22 caused by rainwater or the like can be reduced.

  Note that the width of the third plate-like portion 23Ad in the Z direction may be smaller than the width of the second plate-like portion 23Ab in the Z direction. Furthermore, the lower end in the Z direction of the third plate-like portion 23Ad may be positioned above the position in the Z direction of the fixture 24d of the clamp member 24. Accordingly, when the fixture 4 is attached to the second plate-like portion 23Ab by using a tool, the fixing portion can be hardly hidden by the third plate-like portion 23Ad, so that the clamp member 24 can be easily attached to the first beam member 23A. , Workability is improved.

«Third embodiment»
The third embodiment is different from the first embodiment and the second embodiment in that the through hole 23Ac of the first beam member 23A is a long hole as shown in FIG. 7A. Specifically, the longitudinal direction of the first beam member 23A is provided along the Y direction so as to intersect the longitudinal direction of the tubular member 22, and the through hole 23Ac is formed in the second plate-like portion 23Ab of the first beam member 23A. It is a long hole along the Y direction provided.

  Accordingly, the clamp member 24 can be attached with its position adjusted along the Y direction. Therefore, even when the interval between the tubular members 22 adjacent to each other in the Y direction is shifted from the design value at the time of construction, the clamp member 24 Can be attached to the tubular member 22. Thereby, the workability of the structure mount 2 can be enhanced. Further, as shown in FIG. 7B, a plurality of first uneven portions 23Ac1 are provided on the inner periphery of the through hole 23Ac that is long in the Y direction, and a washer having a second uneven portion 25a that engages with the first uneven portion 23Ac1. The member 25 may be used. Specifically, the washer member 25 includes a plate portion 25b, a second uneven portion 25a disposed on the outer periphery of the plate portion 25b, and a hole 25c provided in the plate portion 25b. Thereby, the clamp member 24 moves along the through hole 23Ac of the first beam member 23A due to the thermal expansion / contraction of the member due to the temperature difference after the construction of the structural frame 2 and the structural frame 2 It is possible to reduce the damage caused by the deformation.

  As shown in FIG. 8, the first beam member 23A may be arranged along the Y direction so as to intersect the longitudinal direction of the tubular member 22, and a groove 23Ae may be provided instead of the through hole 23Ac. Specifically, the groove 23Ae is provided on the second plate-like portion 23Ab of the first beam member 23A, and is provided on the surface of the second plate-like portion 23Ab extending in the Y direction and facing the clamp member 24. A fixing tool 24d is inserted and fixed in the groove 23Ae. The groove 23Ae has a wider width in the Z direction on the back side than the opening side, and may have a shape that can engage the head or nut of the bolt constituting the fixture 24d. Thereby, since the clamp member 24 can be arrange | positioned in a free position along the longitudinal direction of the 1st beam member 23A, the work gantry 2 can obtain higher workability.

  In the above-described embodiment, the solar cell module is shown as an example of the structure supported by the structure mount 2, but the structure is not limited thereto. For example, the structure mount 2 can be used as a mount for roofing materials such as a carport.
