[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 4.

[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 reinforcing 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 vertical direction when the solar power generation fence 11 is installed, and direction X, which is perpendicular to direction Z. The reinforcing member 31 is a plate-shaped member and is laminated with the solar cell sheet 21 in at least a portion of it. The reinforcing member 31 is generally shaped along a plane that includes directions X and Z. The frame 91 supports the outer periphery of the solar cell sheet 21 and the reinforcing 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. 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 Figures 2 to 4, the solar cell sheet 21 comprises a planar first base portion 22, a plurality of first inclined portions 23 adjacent to the first base portion 22 and bending in a direction outside the main surface (the surface including directions X and Z) of the first base portion 22, and a plurality of first through holes 24 extending to at least a portion of the boundary between the first base portion 22 and the first inclined portions 23. The first through-hole 24 separates a portion of the boundary between the first base portion 22 and the first inclined portion 23.

[0013] As shown in Figure 4, the first inclined portion 23 may include a first curved portion 231 adjacent to the first base portion 22, and a first flat portion 232 adjacent to the side of the first curved portion 231 opposite to the side adjacent to the first base portion 22.

[0014] The main surface of the first planar portion 232 is inclined with respect to the main surface of the first base portion 22. The normal direction of the main surface of the first base portion 22 is the direction Y which is orthogonal to the direction X and the direction Z, and the normal direction of the main surface of the first planar portion 232 is the direction P which intersects the direction Y. The angle formed by the direction P and the direction Y is the angle Q, and the angle Q is preferably an acute angle.

[0015] As shown in FIG. 3, the first through-hole 24 may be provided in three directions, namely, the direction X, the opposite direction of the direction Z, and the opposite direction of the direction X, when viewed from the first inclined portion 23, and the first through-holes 24 in each direction may be continuous. That is, the first through-hole 24 may extend in a U-shaped (C-shaped) manner so as to surround the first inclined portion 23. Also, the first base portion 22 and the first inclined portion 23 may be continuous in the direction Z when viewed from the first inclined portion 23.

[0016] The first inclined portion 23 may be two-dimensionally arranged along the direction X and the direction Z. A total of four first inclined portions 23, two along the direction X and two along the direction Z, may be two-dimensionally arranged in the region A.

[0017] As shown in FIGS. 2 to 4, the solar cell sheet 21 further includes a power generation portion 26 (the hatched portion shown in FIGS. 2 and 3), wirings 271, 272, 273, and 274.

[0018] The power generation portion 26 includes a photoelectric conversion layer in a power generation element such as a perovskite solar cell, a dye-sensitized solar cell, or an organic thin-film solar cell, and is a portion that converts irradiated sunlight into electrical energy. At least a part of the power generation portion 26 is provided on the first inclined portion 23. Also, at least a part of the power generation portion 26 may be provided on the first planar portion 232 (FIG. 4). The solar cell sheet 21 includes a light receiving surface 28 on the surface at a position corresponding to the power generation portion 26.

[0019] Multiple power generation units 26 may be arranged two-dimensionally along directions X and Z. Within region A, a total of four power generation units 26 may be arranged two-dimensionally: two along direction X and two along direction Z.

[0020] 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, at least in part, on the first base portion 22.

[0021] 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.

[0022] The wiring cable 93 may be connected to external equipment via a power converter (not shown) or the like.

[0023] 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.

[0024] As shown in Figures 2 to 4, the reinforcing member 31 comprises a planar second base portion 32, at least a portion of which is laminated onto the first base portion 22; a plurality of second inclined portions 33 adjacent to the second base portion 32, bending in a direction outside the main surface of the second base portion 32 (the surface including directions X and Z), and at least a portion of which is laminated onto the first inclined portion 23; and a plurality of second through holes 34 extending to at least a portion of the boundary between the second base portion 32 and the second inclined portions 33 and communicating with the first through hole 24. The second through-hole 34 separates a portion of the boundary between the second base portion 32 and the second inclined portion 33.

[0025] As shown in Figure 3, the second through-holes 34 may be provided in three directions when viewed from the second inclined portion 33: in direction X, in the opposite direction of direction Z, and in the opposite direction of direction X, and the second through-holes 34 in each direction may be continuous. That is, the second through-holes 34 may extend in a U-shape so as to surround the second inclined portion 33.

[0026] As shown in Figures 2 to 4, the second inclined portions 33 may be arranged two-dimensionally along directions X and Z. Within region A, a total of four second inclined portions 33 may be arranged two-dimensionally: two along direction X and two along direction Z.

[0027] The reinforcing member 31 is made of metal materials such as stainless steel, aluminum alloy, titanium alloy, and nickel alloy; resin materials such as polycarbonate and polyethylene terephthalate; or composite materials such as fiber-reinforced resin. The reinforcing member 31 may be formed by applying a load in direction Y or the like to the second inclined portion 33 to the second base portion 32 through plastic deformation or softening bending, thereby deforming the second inclined portion 33 in a direction outside the main plane of the second base portion 32. If the reinforcing member 31 is made of a metal material, it can be easily formed by plastic deformation at room temperature.

[0028] The solar cell sheet 21 may be flexible, and at least a portion of the second base portion 32 may be laminated onto the first base portion 22, and at least a portion of the second inclined portion 33 may be laminated onto the first inclined portion 23, so that the first inclined portion 23 is bent in a direction out of the main plane of the first base portion 22. In this case, at least a portion of the second base portion 32 may be joined to the first base portion 22, and at least a portion of the second inclined portion 33 may be joined to the first inclined portion 23.

[0029] The solar cell sheet 21 may have a shape in which the first inclined portion 23 is bent in a direction outward from the main plane of the first base portion 22. In this case, the reinforcing member 31 may be omitted.

[0030] As shown in Figure 4, when wind in direction Y strikes one side of the solar power generation fence 11, the wind can pass through the second through-hole 34 and the first through-hole 24 to the other side of the solar power generation fence 11, as shown in the ventilation path W1. In other words, the first through-hole 24 and the second through-hole 34 constitute a ventilation path W1 that penetrates the solar power generation fence 11. If the reinforcing member 31 is omitted, the first through-hole 24 constitutes a ventilation path W1 that penetrates the solar power generation fence 11.

[0031] The effects of the first embodiment described above will be explained below.

[0032] The solar power generation fence 11 comprises a solar cell sheet 21 having a first base portion 22, a plurality of first inclined portions 23 adjacent to the first base portion 22 and bending in a direction out of the main plane of the first base portion 22, a plurality of first through holes 24 extending to at least a part of the boundary between the first base portion 22 and the first inclined portions 23, a power generation unit 26 provided at least a part of the first inclined portion 23, and the wiring connected to the power generation unit 26, the first through holes 24 constituting a ventilation path W1. The ventilation path W1 makes it possible to reduce the wind load acting on the solar power generation fence 11 during strong winds, thereby improving the wind pressure resistance of the solar power generation fence 11. This makes it possible to provide a solar power generation fence 11 that can be made larger and has greater flexibility in terms of installation location.

[0033] The solar power generation fence 11 may further include a reinforcing member 31 that is close to the solar cell sheet 21 and has a second through-hole 34 that communicates with the first through-hole 24 to form a ventilation path W1. The ventilation path W1 makes it possible to reduce the wind load acting on the solar power generation fence 11 during strong winds, thereby improving the wind pressure resistance of the solar power generation fence 11. Furthermore, the wind load acting on the solar power generation fence 11 during strong winds can be supported by both the solar cell sheet 21 and the reinforcing member 31, thereby improving the wind pressure resistance of the solar power generation fence 11.

[0034] The reinforcing member 31 is a plate-shaped member and comprises a second base portion 32, at least a part of which is laminated onto the first base portion 22, and a plurality of second inclined portions 33 adjacent to the second base portion 32, bending in a direction out of the main plane of the second base portion 32, and at least a part of which is laminated onto the first inclined portion 23, and the second through hole 34 may extend to at least a part of the boundary between the second base portion 32 and the second inclined portions 33. By forming the reinforcing member 31 through plastic deformation or softening and bending processes, it becomes possible to create a ventilation path W1. Furthermore, it becomes possible to reduce the cost of the solar power generation fence 11.

[0035] The first inclined portion 23 comprises a first curved portion 231 adjacent to the first base portion 22 and a first flat portion 232 adjacent to the side of the first curved portion 231 opposite to the side adjacent to the first base portion 22, and at least a part of the power generation portion 26 may be provided on the first flat portion 232. In the bent portion of the solar cell sheet 21, bending stress acts on the power generation section 26 provided in that portion. During strong winds, this bending stress and the stress due to the wind load superimposed, resulting in high stress. However, by providing at least a portion of the power generation section 26 on the first flat section 232, the area of ​​the power generation section 26 on which the bending stress acts can be reduced. This improves the wind pressure resistance of the solar power generation fence 11.

[0036] The normal direction of the main surface of the first planar portion 232 may intersect the normal direction of the main surface of the first base portion 22 at an acute angle. This makes it possible to reduce the angle between direction P, which is the normal direction of the main surface of the light-receiving surface 28 located on the first planar section 232, and the direction of the sun at noon, when the solar power generation fence 11 is installed with direction X as the east-west direction, thereby increasing 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, thereby improving the wind pressure resistance of the solar power generation fence 11.

[0037] The first through-hole 24 may extend in a U-shape so as to surround the first inclined portion 23. This makes it easier to significantly bend the first inclined portion 23 in a direction outward from the main plane of the first base portion 22, and by enlarging the first through-hole 24, the flow resistance of the ventilation path W1 can be reduced, thereby improving the wind pressure resistance of the solar power generation fence 11.

[0038] The first inclined portion 23 may be arranged two-dimensionally along two intersecting directions. This allows the solar power generation fence 11 to be ventilated uniformly over a wide area, thereby improving the wind pressure resistance of the solar power generation fence 11.

[0039] 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.

[0040] At least a portion of the above wiring may be provided on the first base portion 22. This simplifies the wiring structure and makes it possible to reduce the cost of the solar power fence 11.

[0041] The second through-hole 34 may extend in a U-shape so as to surround the second inclined portion 33. This makes it easier to bend the second inclined portion 33 significantly in the direction outward from the main plane of the second base portion 32, and by enlarging the second through-hole 34, the flow resistance of the ventilation path W1 can be reduced, thereby improving the wind pressure resistance of the solar power generation fence 11.

[0042] The reinforcing member 31 may be made of a metal material. This allows the reinforcing member 31 to be easily formed by plastic deformation at room temperature, enabling further cost reduction of the solar power generation fence 11.

[0043] [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 5. 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.

[0044] Figure 5 is a side view (cross-sectional view) showing the structure of the solar power generation fence 12, and corresponds to Figure 4 of the solar power generation fence 11.

[0045] As shown in Figure 5, the solar power generation fence 12 includes a solar cell sheet 41 and a reinforcing member 51.

[0046] The solar cell sheet 41 comprises a planar first base portion 22, a plurality of first inclined portions 43 adjacent to the first base portion 22 and bent in a direction out of the main plane of the first base portion 22, and a plurality of first through holes 44 extending to at least a portion of the boundary between the first base portion 22 and the first inclined portions 43. The first through-hole 44 separates a portion of the boundary between the first base portion 22 and the first inclined portion 43.

[0047] The first inclined portion 43 may include a first curved portion 431 adjacent to the first base portion 22, and a first flat portion 432 adjacent to the side of the first curved portion 431 opposite to the side adjacent to the first base portion 22.

[0048] The main surface of the first planar portion 432 is substantially parallel to the main surface of the first base portion 22. The normal direction of the main surface of the first base portion 22 is direction Y, and the normal direction of the main surface of the first planar portion 432 is direction R, which is substantially parallel to direction Y.

[0049] The solar cell sheet 41 is equipped with a power generation unit 46.

[0050] The power generation unit 46 is the part that converts irradiated sunlight into electrical energy, and is equipped with a photoelectric conversion layer for power generation elements such as perovskite solar cells, dye-sensitized solar cells, and organic thin-film solar cells. At least a portion of the power generation unit 46 is provided on the first inclined section 43. Furthermore, at least a portion of the power generation unit 46 may be provided on the first planar section 432. The solar cell sheet 41 has a light-receiving surface 48 on its surface at a position corresponding to the power generation unit 46.

[0051] Wiring 273 and wiring 274 (not shown) are connected to the power generation unit 46.

[0052] The reinforcing member 51 is a plate-shaped member. The reinforcing member 51 includes a planar second base portion 32, at least a portion of which is laminated on the first base portion 22; a plurality of second inclined portions 53 adjacent to the second base portion 32, bending in a direction out of the main plane of the second base portion 32, and at least a portion of which is laminated on the first inclined portion 43; and a second through-hole 54 extending to at least a portion of the boundary between the second base portion 32 and the second inclined portions 53 and communicating with the first through-hole 44. The second through-hole 54 separates a portion of the boundary between the second base portion 32 and the second inclined portion 53.

[0053] When wind in direction Y strikes one side of the solar power generation fence 12, the wind can pass through the second through-hole 54 and the first through-hole 44 to the other side of the solar power generation fence 12, as in the ventilation path W2. In other words, the first through-hole 44 and the second through-hole 54 constitute a ventilation path W2 that penetrates the solar power generation fence 12.

[0054] The effects of the second embodiment described above will be explained below.

[0055] The solar power generation fence 12 comprises a solar cell sheet 41 having a first base portion 22, a plurality of first inclined portions 43 adjacent to the first base portion 22 and bending in a direction out of the main plane of the first base portion 22, a plurality of first through holes 44 extending to at least a part of the boundary between the first base portion 22 and the first inclined portions 43, a power generation unit 46 provided at least a part of the first inclined portion 43, and the wiring connected to the power generation unit 46, the first through holes 44 constituting a ventilation path W2. The ventilation path W2 makes it possible to reduce the wind load acting on the solar power generation fence 12 during strong winds, thereby improving the wind pressure resistance of the solar power generation fence 12. This makes it possible to provide a solar power generation fence 12 that can be made larger and has greater flexibility in terms of installation location.

[0056] The normal direction of the main surface of the first planar portion 232 may be substantially parallel to the normal direction of the main surface of the first base portion 22. This makes it possible to suppress the width of the solar power generation fence 12 in direction Y, thereby increasing the flexibility of the installation location of the solar power generation fence 12.

[0057] [Third Embodiment] The structure of the solar power generation fence 13 according to the third embodiment of the present invention will be described below with reference to Figure 6. 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.

[0058] Figure 6 is a side view (cross-sectional view) showing the structure of the solar power generation fence 13, and corresponds to Figure 4 of the solar power generation fence 11.

[0059] As shown in Figure 6, the solar power generation fence 13 includes a solar cell sheet 61 and a reinforcing member 71.

[0060] The solar cell sheet 61 comprises a planar first base portion 22, a plurality of first inclined portions 63 adjacent to the first base portion 22 and bent in a direction out of the main plane of the first base portion 22, and a plurality of first through holes 64 extending to at least a portion of the boundary between the first base portion 22 and each of the first inclined portions 63. The first through-hole 64 separates a portion of the boundary between the first base portion 22 and the first inclined portion 63.

[0061] The first inclined portion 63 has a curved shape in which the entire surface is curved in the same direction. For example, the first inclined portion 63 may be a cylindrical surface as a whole, or its curvature may vary depending on the location.

[0062] The solar cell sheet 61 includes a power generation unit 66.

[0063] The power generation unit 66 is the part that converts irradiated sunlight into electrical energy, and is equipped with a photoelectric conversion layer for power generation elements such as perovskite solar cells, dye-sensitized solar cells, and organic thin-film solar cells. At least a portion of the power generation unit 66 is provided on the first inclined section 63. The solar cell sheet 61 has a light-receiving surface 68 on its surface at a position corresponding to the power generation unit 66.

[0064] Wiring 273 and wiring 274 (not shown) are connected to the power generation unit 66.

[0065] The reinforcing member 71 is a plate-shaped member. The reinforcing member 71 includes a planar second base portion 32, at least a portion of which is laminated on the first base portion 22; a plurality of second inclined portions 73 adjacent to the second base portion 32, bending in a direction out of the main plane of the second base portion 32, and at least a portion of which is laminated on the first inclined portion 63; and a second through-hole 74 extending to at least a portion of the boundary between the second base portion 32 and the second inclined portions 73 and communicating with the first through-hole 64. The second through-hole 74 separates a portion of the boundary between the second base portion 32 and the second inclined portion 73.

[0066] When wind in direction Y strikes one side of the solar power generation fence 13, the wind can pass through the second through-hole 74 and the first through-hole 64 to the other side of the solar power generation fence 13, as in the ventilation path W3. In other words, the first through-hole 64 and the second through-hole 74 constitute a ventilation path W3 that penetrates the solar power generation fence 13.

[0067] The effects of the third embodiment described above will be explained below.

[0068] The solar power generation fence 13 comprises a solar cell sheet 61 having a first base portion 22, a plurality of first inclined portions 63 adjacent to the first base portion 22 and bending in a direction out of the main plane of the first base portion 22, a plurality of first through holes 64 extending to at least a part of the boundary between the first base portion 22 and the first inclined portions 63, a power generation unit 66 provided at least a part of the first inclined portion 63, and the wiring connected to the power generation unit 66, the first through holes 64 constituting a ventilation path W3. The ventilation path W3 makes it possible to reduce the wind load acting on the solar power generation fence 13 during strong winds, thereby improving the wind pressure resistance of the solar power generation fence 13. This makes it possible to provide a solar power generation fence 13 that can be made larger and has greater flexibility in terms of installation location.

[0069] The first inclined portion 63 has a curved shape in which the entire structure curves in the same direction. In the portion of the solar cell sheet 61 that is bent, bending stress acts on the power generation section 66 provided in that portion. During strong winds, this bending stress and the stress due to the wind load superimposed, resulting in high stress. However, since the entire first inclined section 63, on which at least a part of the power generation section 66 is provided, has a curved shape that curves in the same direction, the curvature of the bending of the power generation section 66 can be reduced, and the bending stress on the power generation section 66 can be reduced. This improves the wind pressure resistance of the solar power generation fence 13.

[0070] [Fourth Embodiment] The structure of the solar power generation fence 14 according to the fourth embodiment of the present invention will be described below with reference to Figure 7. 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.

[0071] Figure 7 is a side view (cross-sectional view) showing the structure of the solar power generation fence 14, and corresponds to Figure 4 of the solar power generation fence 11.

[0072] As shown in Figure 7, the solar power generation fence 14 comprises two solar cell sheets 21 and two reinforcing members 31. The two solar cell sheets 21 are arranged so that the faces opposite to the bent side of each first inclined portion 23 are in close proximity to each other. The two reinforcing members 31 are positioned between the two solar cell sheets 21. The number of reinforcing members 31 is not limited to two; it may be one or the like.

[0073] When wind in direction Y strikes one side of the solar power generation fence 14, the wind can pass through the second through-hole 34 and the first through-hole 24 to the other side of the solar power generation fence 14, as in the ventilation path W4. That is, the first through-hole 24 and the second through-hole 34 constitute a ventilation path W4 that penetrates the solar power generation fence 14.

[0074] The effects of the fourth embodiment described above will be explained below.

[0075] The solar power generation fence 14 is equipped with two solar cell sheets 21, and the faces of each solar cell sheet 21 are in close proximity to each other on the side opposite to the side where the first inclined portion 23 is bent. This allows the amount of power generated by the power generation unit 26 to be increased when the solar power generation fence 14 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.

[0076] The solar power generation fence 14 comprises two solar cell sheets 21 and a reinforcing member 31, wherein the faces of each solar cell sheet 21 are close together on the side opposite to the side where the first inclined portion 23 is bent, and the reinforcing member 31 may be located between the two solar cell sheets 21. This makes it possible to support the wind load acting on the solar power generation fence 14 during strong winds with both the solar cell sheet 21 and the reinforcing member 31, thereby improving the wind pressure resistance of the solar power generation fence 14.

[0077] [Fifth Embodiment] The structure of the solar power generation fence 15 according to the fifth 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.

[0078] Figure 8 is a perspective view showing the structure of the solar power generation fence 15, which corresponds to Figure 2 of the solar power generation fence 11.

[0079] As shown in Figure 8, the solar power generation fence 15 includes a solar cell sheet 21 and a reinforcing member 81. The reinforcing member 81 is a mesh fence or a profiled fence and is positioned close to the solar cell sheet 21. (In Figure 8, the solar cell sheet 21 and the reinforcing member 81 are shown separately for clarity, but in reality, the solar cell sheet 21 and the reinforcing member 81 are positioned close to each other.)

[0080] When wind in direction Y strikes one side of the solar power generation fence 15, the wind can pass through the gaps 84 in the mesh fence or the shaped fence and the first through-hole 24 to the other side of the solar power generation fence 15.

[0081] The effects of the fifth embodiment described above will be explained below.

[0082] The solar power generation fence 15 has a reinforcing member 81 which is the mesh fence or profiled fence. The mesh fences and profiled fences mentioned above are widely used and low-cost, which makes it possible to reduce the cost of the solar power generation fence 15.
