[0008] [First Embodiment] The structure of the solar power generation fence 11 according to the first embodiment of the present invention will be described below with reference to Figures 1 to 7.

[0009] Figure 1 is a perspective view showing the structure of the solar power generation fence 11.

[0010] As shown in Figure 1, the solar power generation fence 11 comprises a solar cell sheet 21, a fence member 31, a frame 91, and a wiring cable 93. The solar cell sheet 21 is generally shaped along a plane that includes direction Z, which is the vertically upward direction when the solar power generation fence 11 is installed, and direction X, which is perpendicular to direction Z. The fence members 31 consist of various fence members, including mesh fences, profiled fences, and louver fences. The fence member 31 is generally shaped to follow a plane that includes directions Z and X. Furthermore, the fence member 31 is positioned close to the solar cell sheet 21 along direction Y, which is perpendicular to directions Z and X. The frame 91 supports the outer periphery of the solar cell sheet 21 and the fence member 31. The frame 91 has a lower end portion 92 in the opposite direction of direction Z, and the lower end portion 92 is fixed by embedding it in the ground or bolting it to the foundation structure.

[0011] Figure 2 is a perspective view of area A in Figure 1, showing the structure of the solar power generation fence 11. In Figure 2, the solar cell sheet 21 and the fence member 31 are shown separately for clarity, but in reality, the solar cell sheet 21 and the fence member 31 are placed in close proximity. Figure 3 is a front view of area A in Figure 1, showing the structure of the solar power generation fence 11. Figure 4 is a side view (cross-sectional view) of cross-section BB in Figure 3, showing the structure of the solar power generation fence 11.

[0012] As shown in FIGS. 2 to 4, the solar cell sheet 21 includes a planar base portion 22, a plurality of deformable portions 23 adjacent to the base portion 22 and bendable in a direction outside the main surface (the surface including the X direction and the Z direction) of the base portion 22, and a gap 24 extending at least partially along the boundary between the base portion 22 and the deformable portion 23. The gap 24 separates a part of the boundary between the base portion 22 and the deformable portion 23.

[0013] As shown in FIG. 4, the deformable portion 23 may include a large deformation region 231 adjacent to the base portion 22 and a small deformation region 232 adjacent to the side opposite to the side adjacent to the base portion 22 of the large deformation region 231 and having a greater thickness than the large deformation region 231.

[0014] A reinforcing plate 41 may be joined to the side of the small deformation region 232 where the fence member 31 is located. The reinforcing plate 41 is a member made of a resin material such as polycarbonate, ASA resin, polyvinyl chloride, polyethylene, polypropylene, or a composite material such as a fiber-reinforced resin.

[0015] The thickness of the large deformation region 2 is T1, and the thickness of the small deformation region 232 is T2, and T2 may be greater than T1.

[0016] The members constituting the small deformation region 232 are the solar cell sheet 21 and the reinforcing plate 41, and the number of members in the thickness direction is two. The member constituting the large deformation region 231 is the solar cell sheet 21, and the number of members in the thickness direction is one. Thus, the number of members in the thickness direction constituting the small deformation region 232 may be greater than the number of members in the thickness direction constituting the large deformation region 231.

[0017] The solar cell sheet 21 and the reinforcing plate 41 may be formed of an integral member rather than separate members.

[0018] As shown in Figure 3, the gaps 24 may be provided in three directions when viewed from the deformed portion 23: in direction X, in the opposite direction of direction Z, and in the opposite direction of direction X, and the gaps 24 in each direction may be continuous. That is, the gaps 24 may extend in a U-shape so as to surround the deformed portion 23. The base portion 22 and the deformation portion 23 may be continuous on the side in direction Z when viewed from the deformation portion 23.

[0019] The deformation parts 23 may be arranged two-dimensionally along directions X and Z. For example, a total of four deformation parts 23 may be arranged two-dimensionally within region A, two along direction X and two along direction Z.

[0020] As shown in Figures 2 and 3, the solar cell sheet 21 further includes a power generation unit 26 (the hatched portion shown in the figure), wiring 271, wiring 272, wiring 273, and wiring 274. The power generation unit 26, wiring 271, wiring 272, wiring 273, and wiring 274 may be provided inside the solar cell sheet 21.

[0021] The power generation unit 26 is the part that includes a photoelectric conversion layer in power generation elements such as perovskite solar cells, dye-sensitized solar cells, and organic thin-film solar cells, and converts irradiated sunlight into electrical energy. The power generation unit 26 is provided in at least part of the deformation unit 23.

[0022] As shown in Figure 4, the power generation unit 26 may be provided in at least a portion of the small deformation region 232.

[0023] As shown in Figures 2 to 4, the solar cell sheet 21 has a light-receiving surface 28 on the surface corresponding to the power generation unit 26.

[0024] Multiple power generation units 26 may be arranged two-dimensionally along directions X and Z. For example, a total of four power generation units 26 may be arranged two-dimensionally within region A, with two along direction X and two along direction Z.

[0025] Wiring 273 connects the first terminal (not shown) of each power generation unit 26 to wiring 271. Wiring 274 connects the second terminal (not shown) of each power generation unit 26 to wiring 272. Wire 271 connects each of the wires 273 together, and one end is connected to the wiring cable 93 (Figure 1). Similarly, wire 272 connects each of the wires 274 together, and one end is connected to the wiring cable 93. Wiring 273 and wiring 274 may be provided in part on the base portion 22.

[0026] The wiring structure described above is not limited to the structure described above. For example, at least one of the wires 273 and 274 may connect the first terminal or the second terminal of the power generation unit 26 to the first terminal or the second terminal of the other power generation unit 26. Alternatively, at least one end of the wires 273 and 274 may be connected to the wiring cable 93, or at least one of the wires 271 and 272 may be omitted.

[0027] The wiring cable 93 may be connected to external equipment via a power converter (not shown) or the like.

[0028] When sunlight shines on the light-receiving surface 28, the power generation unit 26 generates electricity, creating a potential difference between the first terminal and the second terminal. This creates a potential difference between wiring 273 and wiring 274, and further, between wiring 271 and wiring 272. Therefore, power can be supplied to external equipment via the wiring cable 93.

[0029] As shown in Figures 2 and 4, the fence member 31 may be constructed by combining a plurality of members 32 extending in direction X and a plurality of members 33 (Figure 2) extending in direction Z in a grid pattern.

[0030] Members 32 and 33 can be made of materials such as carbon steel, alloy steels such as stainless steel, metal materials such as aluminum alloys, titanium alloys, and nickel alloys, resin materials such as polyvinyl chloride, polyethylene, and polypropylene, composite materials such as fiber-reinforced resins, and wood.

[0031] The ventilation holes 34 are located between adjacent members 32 and between adjacent members 33.

[0032] When viewed from the side of the fence member 31 along direction Y, at least a portion of the position corresponding to the ventilation hole 34 overlaps with at least a portion of the position corresponding to the deformed portion 23 (C in Figures 2 and 4). In other words, at least a portion of the ventilation hole 34 is provided in a position corresponding to the deformed portion 23 in direction Y. When viewed from the side of the fence member 31 along direction Y, the position corresponding to the ventilation hole 34 may include the position corresponding to the deformed portion 23. In other words, the ventilation hole 34 may be provided in a region in direction Y that includes the position corresponding to the deformed portion 23.

[0033] The direction in which member 32 extends is not limited to direction X. Also, the direction in which member 33 extends is not limited to direction Z. Member 32 may be omitted. In this case, the ventilation holes 34 are located between adjacent members 33. Member 33 may be omitted. In this case, the ventilation holes 34 are located between adjacent members 32.

[0034] The solar cell sheet 21 and the fence member 31 may be joined together in at least part. For example, the solar cell sheet 21 and the member 32 may be joined together at the joint 36 (Figure 4). Methods of joining include adhesive bonding, bolt fastening, locking structures, and fastening with clamping members.

[0035] Figure 5 is a perspective view showing the state of the solar power generation fence 11 in Figure 2 when a wind load is applied. Figure 6 is a side view (cross-sectional view) showing the state of the solar power generation fence 11 in Figure 4 when a wind load is applied.

[0036] As shown in Figures 5 and 6, when wind W1 (Figure 6) in direction Y hits the right side (Figure 6) of the solar power generation fence 11, the wind W1 passes through the ventilation holes 34 and hits the right side (Figure 6) of the solar cell sheet 21 and reinforcing plate 41. As a result, a wind load in direction Y acts on the deformed portion 23. Due to this wind load, the deformed portion 23 bends in a direction (direction Y) outside the main surface (the surface including directions X and Z) of the base portion 22, and the gap 24 expands. As a result, a ventilation path W2 (Figure 6) that penetrates the solar power generation fence 11 is formed. That is, the gap 24 and the ventilation holes 34 constitute the ventilation path W2 that penetrates the solar power generation fence 11.

[0037] Figure 7 is a side view (cross-sectional view) showing the state of the solar power generation fence 11 in Figure 4 when a wind load is applied.

[0038] As shown in Figure 7, when wind W3, which is in the opposite direction to direction Y, hits the left side of the solar power generation fence 11, wind W3 hits the left side of the solar cell sheet 21. As a result, a wind load in the opposite direction to direction Y acts on the deformed portion 23. If the ventilation holes 34 are located in a region that includes the position corresponding to the deformed portion 23 in direction Y (C in Figures 2 and 4), the wind load can cause the deformed portion 23 to bend in a direction outside the main plane of the base portion 22 and in the direction where the fence member 31 is located (opposite to direction Y), thereby expanding the gap 24. This creates a ventilation path W4 that penetrates the solar power generation fence 11. In other words, the gap 24 and the ventilation holes 34 constitute the ventilation path W4 that penetrates the solar power generation fence 11.

[0039] The effects of the first embodiment described above will be explained below.

[0040] A solar power generation fence 11 comprises a solar cell sheet 21 and a fence member 31 positioned in close proximity to the solar cell sheet 21, wherein the solar cell sheet 21 comprises a base portion 22, a plurality of deformable portions 23 adjacent to the base portion 22 and capable of bending in a direction out of the main plane of the base portion 22 by wind load, a gap 24 extending in at least a part of the boundary between the base portion 22 and the deformable portions 23, a power generation portion 26 provided in at least a part of the deformable portion 23, and the wiring connected to the power generation portion 26, and the fence member 31 comprises ventilation holes 34 provided in a position corresponding to the deformable portions 23 in the direction in which the solar cell sheet 21 and the fence member 31 are positioned.

[0041] Wind W1 in direction Y allows the gaps 24 and ventilation holes 34 to form a ventilation path W2 that penetrates the solar power generation fence 11. This reduces the wind load acting on the solar power generation fence 11, improving its wind pressure resistance and making it possible to provide a solar power generation fence 11 that can be made larger and has greater flexibility in installation location. Furthermore, by providing at least a portion of the power generation unit 26 on the deformable portion 23, the area of ​​the power generation unit 26 can be increased, making it possible to increase the amount of power generated by the power generation unit 26. If the amount of power generated by the power generation unit 26 remains the same, the solar cell sheet 21 can be made smaller, making it possible to improve the wind pressure resistance of the solar power generation fence 11.

[0042] The ventilation holes 34 may be provided in a region that includes a position corresponding to the deformed portion 23 in the arrangement direction of the solar cell sheet 21 and the fence member 31.

[0043] Wind W3 in the opposite direction to direction Y allows the gap 24 and ventilation holes 34 to form a ventilation path W4 that penetrates the solar power generation fence 11. This reduces the wind load acting on the solar power generation fence 11 for winds in both directions W1 and W3, improving the wind pressure resistance of the solar power generation fence 11 and making it possible to provide a solar power generation fence 11 that can be made larger and has greater flexibility in installation location.

[0044] The deformable portion 23 may include a large deformable region 231 adjacent to the base portion 22, and a small deformable region 232 adjacent to the side of the large deformable region 231 opposite to the side adjacent to the base portion 22, and having a greater thickness than the large deformable region 231.

[0045] A large bending moment acts on the position adjacent to the base portion 22 due to the wind load. By providing a large deformation region 231 at this position, the bending of the deformed portion 23 can be increased, and the gap 24 can be enlarged. As a result, the flow resistance of the ventilation path W2 can be reduced. This reduces the wind load acting on the solar power generation fence 11, and makes it possible to improve the wind pressure resistance of the solar power generation fence 11.

[0046] At least a portion of the power generation unit 26 may be provided in the small deformation region 232. In the bent portion of the deformed section 23, bending stress acts on the power generation section 26 provided in that section, corresponding to the deformation. When the thickness T2 of the small deformation region 232 is greater than the thickness T1 of the large deformation region 231, the bending stress acting on the small deformation region 232 can be made smaller compared to the bending stress acting on the large deformation region 231. By providing at least a portion of the power generation section 26 in the small deformation region 232, the area of ​​the power generation section 26 that is subjected to large bending stress during strong winds, etc., can be reduced. This makes it possible to improve the wind pressure resistance of the solar power generation fence 11.

[0047] The number of members in the thickness direction that constitute the small deformation region 232 may be greater than the number of members in the thickness direction that constitute the large deformation region 231. This allows the thickness of the small deformation region 232 to be greater than the thickness of the large deformation region 231 with a simple configuration, making it possible to reduce the cost of the solar power generation fence 11.

[0048] The gap 24 may extend in a U-shape so as to surround the deformed portion 23. This allows for greater bending of the deformed portion 23 and an enlargement of the gap 24. As a result, the flow resistance of the ventilation path W2 can be reduced. This reduces the wind load acting on the solar power generation fence 11 and improves the wind pressure resistance of the solar power generation fence 11.

[0049] The base portion 22 and the deformation portion 23 may be continuous on the vertically upward side. As a result, gravity acting on the deformable portion 23 acts in the direction that extends the deformable portion 23. Consequently, when wind W1 repeatedly hits the solar power generation fence 11, or when wind W1 and wind W3 repeatedly hit it alternately, the deformable portion 23 can stably bend repeatedly.

[0050] The deformation portion 23 may be arranged two-dimensionally along two intersecting directions. This allows the solar power generation fence 11 to be ventilated over a wide area, improving its wind pressure resistance.

[0051] Multiple power generation units 26 may be arranged two-dimensionally along two intersecting directions. This makes it possible to increase the amount of power generated by the power generation unit 26.

[0052] At least a portion of the above wiring may be provided on the base portion 22. This simplifies the wiring structure and makes it possible to reduce the cost of the solar power fence 11.

[0053] The solar cell sheet 21 and the fence member 31 may be connected in at least part of the same area. This makes it possible to increase the strength of the solar cell sheet 21 and the fence member 31 as a single unit, thereby improving the wind pressure resistance of the solar power generation fence 11.

[0054] [Second Embodiment] The structure of the solar power generation fence 12 according to the second embodiment of the present invention will be described below with reference to Figure 8. However, components having the same configuration as those in the first embodiment will be denoted by the same reference numerals, and their descriptions will be omitted as appropriate.

[0055] Figure 8 is a side view (cross-sectional view) showing the state of the solar power generation fence 12 when a wind load is applied, and corresponds to Figure 6 of the solar power generation fence 11.

[0056] As shown in Figure 8, the solar power generation fence 12 comprises two solar cell sheets 21 and a fence member 31. Reinforcement plates 41 may be attached to each of the two solar cell sheets 21.

[0057] The two solar cell sheets 21 are arranged so that the sides opposite to the side where each light-receiving surface 28 is located are in close proximity to each other. The fence member 31 is positioned between the two solar cell sheets 21.

[0058] The deformable portions 23 of the two solar cell sheets 21 may be deformably connected to each other via a connecting portion 51. Alternatively, a reinforcing plate 41 may be interposed between the deformable portion 23 and the connecting portion 51. The connecting portion 51 may be made of a low-elasticity material such as a silicone resin or a polyurethane resin.

[0059] When wind W5 in direction Y hits the right side of the solar power generation fence 12, wind W5 hits the right side of the solar cell sheet 21. As a result, a wind load in direction Y acts on the deformed portion 23 on the right side. This wind load causes the deformed portion 23 on the right side to bend in the direction outside the main plane of the base portion 22 (direction Y), and the gap 24 on the right side expands. Since the left and right deformable sections 23 are connected via the connecting section 51, the left deformable section 23 also bends in the same direction as the right deformable section 23, and the gap 24 on the left side expands. This creates a ventilation path W6 that penetrates the solar power generation fence 12. In other words, the left and right gaps 24 and the ventilation holes 34 constitute the ventilation path W6 that penetrates the solar power generation fence 12.

[0060] The effects of the second embodiment described above will be explained below.

[0061] The solar power generation fence 12 comprises two solar cell sheets 21, and the fence member 31 may be positioned between the two solar cell sheets 21. This makes it possible to increase the amount of power generated by the power generation unit 26 when the solar power generation fence 12 is installed with direction X in the north-south direction, for example, by having sunlight irradiate one light-receiving surface 28 in the morning and the other light-receiving surface 28 in the afternoon.

[0062] The solar power generation fence 12 may be connected in a deformable manner by the deformable portions 23 of two solar cell sheets 21 via a connecting portion 51. This allows the left and right deformable sections 23 to bend in conjunction, and the left and right gaps 24 and ventilation holes 34 to form a ventilation path W6 that penetrates the solar power generation fence 12.

[0063] The connecting portion 51 may be made of a low-elasticity material. This allows the left and right deformable sections 23 to bend in conjunction with each other, resulting in a simple structure. Consequently, the cost of the solar power generation fence 12 can be reduced.

[0064] The following describes some variations of the above embodiments.

[0065] The solar cell sheet 21 is not limited to a shape that generally follows a flat surface, but may also have a shape that follows a curved surface. The fence member 31 is not limited to a shape that generally follows a flat surface, but may also have a shape that follows a curved surface.

[0066] The base portion 22 is not limited to a planar shape, but may also have a curved shape.

[0067] The reinforcing plate 41 may be omitted. The deformed portion 23 may have a uniform thickness. The number of members in the thickness direction that constitute the small deformation region 232 may be the same as the number of members in the thickness direction that constitute the large deformation region 231. Other components besides the solar cell sheet 21 and reinforcing plate 41 may be laminated in the small deformation region 232. Also, other components besides the solar cell sheet 21 may be laminated in the large deformation region 231.

[0068] When viewed from the deformed portion 23, the direction in which the gap 24 is provided is not limited to the three directions of direction X, the opposite direction of direction Z, and the opposite direction of direction X, but may be any of these directions.

[0069] The direction in which the base portion 22 and the deformation portion 23 are continuous is not limited to direction Z, but may be any direction.

[0070] The void 24 is not limited to extending in a U-shape, but may also extend in an L-shape or other shape.

[0071] The deformation portion 23 is not limited to being arranged two-dimensionally along directions X and Z, but may also be arranged two-dimensionally along two intersecting directions, or in a staggered pattern, etc. The power generation unit 26 is not limited to being arranged two-dimensionally along directions X and Z, but may also be arranged two-dimensionally along two intersecting directions, or in a staggered pattern, etc.

[0072] The connection between the solar cell sheet 21 and the fence member 31 is not limited to a configuration in which the solar cell sheet 21 and the member 32 are connected at the connection portion 36. For example, the solar cell sheet 21 and the fence member 31 may be connected with another member interposed between them, or the solar cell sheet 21 and the member 33 may be connected, etc.

[0073] The present invention is not limited to the above embodiments and modifications, and various modifications are possible. [Explanation of Symbols]
