Description

[Technical field]

[0001] The present invention relates to a solar power generation panel stand, a solar power generation device, and a method for installing a solar power generation device. [Background technology]

[0002] Photovoltaic power generation panels are usually installed outdoors and are therefore often subjected to wind pressure. When installing photovoltaic power generation panels, they are firmly fixed to an installation surface such as the ground or a roof so that they can withstand wind pressure. The mounting frame that supports the photovoltaic power generation panels is often fixed to a concrete foundation provided on the ground or a roof, as described in Patent Document 1, for example. Patent Document 1 proposes installing a windbreak device to reduce the wind pressure that the photovoltaic power generation panels are subjected to. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2015-059415 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, even if the windbreak device described in Patent Document 1 is installed, it is necessary to lay a concrete foundation and fix the mounting base to it. Laying a concrete foundation requires a lot of work.

[0005] Furthermore, even if a windbreak is installed, wind may get into the space behind the solar panel, i.e., between the solar panel and the installation surface, and the solar panel may be subjected to pressure (negative pressure) from the back. The foundation and mounting frame must be strong enough to withstand such negative pressure. As described in Patent Document 1, even if the windbreak can reduce the weight of the foundation and mounting frame, when installing solar panels on the flat roof of a building, it is still a lot of work to transport the materials for assembling the windbreak and solar panels to the roof.

[0006] Thus, there is a problem that installing a solar panel on a flat roof is very time-consuming. The present invention aims to solve this problem and to provide a solar panel stand or the like that makes it possible to easily install a solar panel on an installation surface such as a flat roof.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The same elements are designated by the same reference numerals throughout the drawings.

[0012] (Embodiment 1) A solar power generation device 100 according to a first embodiment of the present invention is a device that receives sunlight and generates power. As shown in Fig. 1 which is a perspective view, Fig. 2 which is a plan view, and Figs. 3 to 6 which are side cross-sectional views, the solar power generation device 100 includes a plurality of solar power generation panels 101_a to 101_f and a solar power generation panel stand 102 which is characteristic of the present invention.

[0013] Fig. 3 is a side cross-sectional view taken along line III-III in Fig. 2. Figs. 4 to 6 are enlarged views of the portions circled by dashed dotted lines a to c in Fig. 3, respectively.

[0014] In the following description, when there is no need to distinguish between the solar panels 101_a to 101_f, they are simply referred to as solar panels 101. Furthermore, the directions in which the multiple solar panels 101 are arranged are referred to as the front-rear direction and the left-right direction, and the direction perpendicular to these directions is referred to as the up-down direction.

[0015] The photovoltaic power generation panel 101 is a panel that receives sunlight on its surface and generates power. The photovoltaic power generation panel 101 is appropriately connected by electrical wiring (not shown), and the power generated by the photovoltaic power generation panel 101 is supplied to a load or the like through the electrical wiring, a power conditioner (not shown), or the like.

[0016] The photovoltaic power generation panel 101 is generally also called a solar cell, a solar panel, a photovoltaic power generation module, a solar module, etc. In this embodiment, an example in which six photovoltaic power generation panels 101 are installed will be described.

[0017] Each of the solar panels 101 is disposed so that its surface faces upward and forward, and is inclined at an angle of about 8 degrees with respect to the installation surface G, for example.

[0018] A so-called flexible solar panel is preferably used for each of the solar power generation panels 101. A flexible solar panel is a solar power generation panel in which a resin sheet is provided on the surface instead of a glass plate and the periphery is surrounded by a flexible metal (e.g., aluminum) or resin frame. Such a flexible solar panel is flexible and lighter than a glass panel having a glass plate on its surface. Note that the solar power generation panel 101 may be a crystalline glass panel having a glass plate on its surface.

[0019] The size of each of the solar panels 101 may be determined appropriately, but for example, the length is about 300 to 1000 mm, the width is about 2000 mm, and the thickness is about 3 to 5 mm. The weight of each of the solar panels 101 varies depending on the size, but is generally 2 to 6 kg.

[0020] The solar panel stand 102 is a stand for mounting multiple solar panels 101 on an installation surface G, arranged in the front-rear and left-right directions. The installation surface G is a surface that is appropriately set as an area for mounting the multiple solar panels 101. For the solar panel stand 102, a horizontal surface such as the roof surface of a flat roof is suitable as the installation surface G.

[0021] The solar panel stand 102 includes support legs 103 that support each of the multiple solar panels 101, and a cover 104 that closes the gap between the installation surface G and the peripheral edges of the multiple solar panels 101 arranged in a row on the installation surface G.

[0022] Here, the peripheral portions of the multiple solar panels 101 are composed of the ends that make up the front, back, left and right sides of each solar panel 101, and that are not adjacent to other solar panels 101.

[0023] That is, in this embodiment, the solar power generation panels 101_a and 101_b, the solar power generation panels 101_b and 101_c, the solar power generation panels 101_d and 101_e, and the solar power generation panels 101_e and 101_f are adjacent to each other. Therefore, in this embodiment, the right end portions of the solar power generation panels 101_a and 101_d, the left and right end portions of the solar power generation panels 101_b and 101_e, and the left end portions of the solar power generation panels 101_c and 101_f are not included in the peripheral portion of the multiple solar power generation panels 101. Therefore, in this embodiment, the peripheral portion of the multiple solar power generation panels 101 is composed of the left end portions of the solar power generation panels 101_a and 101_d, the front end portions and rear end portions of the solar power generation panels 101_a to 101_f, and the right end portions of the solar power generation panels 101_c and 101_f.

[0024] Here, "adjacent" means closer than a predetermined distance (e.g., several centimeters). The distance that is the criterion for whether the solar panels 101 are adjacent or not is set to, for example, a distance that prevents wind strong enough to blow the solar panels 101 away from passing through the gaps between the solar panels 101 and entering the rear surface of the solar panels 101.

[0025] The support legs 103 have a length in the front-rear direction, and are attached in pairs to each of the solar power generation panels 101. In the solar power generation device 100 according to this embodiment, six solar power generation panels 101 are installed as described above, and therefore six pairs of support legs 103, that is, twelve support legs 103, are provided.

[0026] One of the pair of support legs 103 is attached at a position a predetermined distance away from the left end of the solar power generation panel 101, and the other is attached at a position a predetermined distance away from the right end of the solar power generation panel 101. Note that the pair of support legs 103 may be attached to each of the left end and the right end of the solar power generation panel 101.

[0027] In detail, each of the support legs 103 has a seat plate 105, a first holding member 106, an inclination angle regulating member 107, and a second holding member 108, as shown in FIGS.

[0028] The material of the members 105-108 constituting the support leg 103 is, for example, stainless steel. By using a material that is resistant to rust, such as stainless steel, it is possible to prevent damage due to rust to objects that have been installed in advance on the installation surface G (for example, a waterproof sheet in the case of a flat roof). Note that the material of the members 105-108 constituting the support leg 103 is not limited to stainless steel, and may be appropriately selected from metals, resins, etc.

[0029] The seat panel 105 has a length in the front-rear direction and is a member placed on an installation surface G. As shown in Fig. 7, the seat panel 105 has an installation panel portion 109, a front panel portion 110, a left panel portion 111_L, and a right panel portion 111_R.

[0030] FIG. 7 shows the seat panel 105, where (a) is a plan view, (b) is a front view, (c) is a bottom view, and (d) is a right side view. The left side view of the seat panel 105 is bilaterally symmetrical with the right side view.

[0031] The installation plate 109 is a plate-like portion that extends in an elongated manner from front to back and is generally rectangular with the left and right corners of the front end portion cut out. The bottom surface of the installation plate 109 is installed on the installation surface G. An adhesive area for adhering to the installation surface G is appropriately provided on the bottom surface of the installation plate 109, as shown by the two-dot chain line AA in FIG. 7(d) . The installation plate 109 is adhered to the installation surface G by double-sided tape attached to this adhesive area AA, or by a coated adhesive. In this way, the solar power generation device 100 is fixed to the installation surface G.

[0032] The front plate portion 110 is a portion that extends obliquely upward and rearward from the front end portion of the installation plate portion 109. The front plate portion 110 is provided with holes 112 for fixing the cover 104, which will be described in detail later, with bolts B (see FIG. 4 for the bolts B).

[0033] The right side plate portion 111_R and the left side plate portion 111_L are portions extending upward from the right end and the left end of the installation plate portion 109, respectively.

[0034] Near the front end of each of the right side plate portion 111_R and the left side plate portion 111_L, a hole 113 located on a straight line extending left and right is provided for attaching the first holding member 106. In addition, near the rear end of each of the right side plate portion 111_R and the left side plate portion 111_L, a hole 114 located on a straight line extending left and right is provided for attaching the inclination angle defining member 107.

[0035] Here, the term "vicinity" refers to a range up to a predetermined distance from a reference portion or position, and will be used in the following in the same sense. For example, "vicinity of the front end" refers to a range up to a predetermined distance from the front end. Also, for example, "vicinity of the rear end" refers to a range up to a predetermined distance from the rear end.

[0036] The inclination angle defining member 107 has a base end attached to the rear end of the seat plate 105 and extends upward from the base end to the tip end. The inclination angle of the photovoltaic panel 101 is defined according to the length of the inclination angle defining member 107.

[0037] In addition, in this embodiment, the inclination angle regulating member 107 extends generally straight up. Therefore, the support legs 103 do not protrude rearward beyond the rear end of the solar panel 101, and the solar panel 101 with the support legs 103 attached can be made compact.

[0038] In detail, as shown in FIG. 8, the inclination angle defining member 107 has a back plate portion 115, a right plate portion 116_R, and a left plate portion 116_L.

[0039] 8A, 8B, and 8C are diagrams showing the inclination angle specifying member 107, in which FIG. 8A is a plan view, FIG. 8B is a front view, and FIG. 8C is a right side view. The left side view of the inclination angle specifying member 107 is bilaterally symmetrical with the right side view.

[0040] The back plate portion 115 is a generally rectangular plate-like portion. As shown in Fig. 8(b), the back plate portion 115 has a hole 117 for fixing the cover 104, which will be described in detail later, with a bolt B near the upper end.

[0041] The right plate portion 116_R and the left plate portion 116_L are flat plate-like portions extending forward from the left and right ends of the back plate portion 115. The upper end portion of each of the right plate portion 116_R and the left plate portion 116_L forms a straight line inclined downward and forward at approximately 8 degrees, and a hole 118 is provided near the upper end portion, located on the straight line extending left and right. A hole 119 is provided near the lower end portion of each of the right plate portion 116_R and the left plate portion 116_L, located on the straight line extending left and right.

[0042] The first holding member 106 is a member attached to the front end of the seat plate 105 in order to hold the solar power generation panel 101. The first holding member 106 is attached to the front end of the seat plate 105 so as to be rotatable about an axis in the left-right direction and so as to be detachable.

[0043] In detail, the first holding member 106 has a holding portion 120 and left and right mounting pieces 121_L, 121_R, as shown in FIG.

[0044] Note that Figure 9 shows the first holding member 106, with Figure 9(a) being a plan view, Figure 9(b) being a front view, and Figure 9(c) being a right side view, and the left side view of the first holding member 106 being bilaterally symmetrical with the right side view.

[0045] 9, the holding portion 120 has a support plate portion 122 and an L-shaped portion 123. The support plate portion 122 is a portion having a generally rectangular flat plate shape. The L-shaped portion 123 is a portion that extends upward from the upper surface of the support plate portion 122 and then bends forward.

[0046] The left and right mounting pieces 121_L, 121_R are small pieces extending downward from the left and right ends of the holding part 120. Each of the left and right mounting pieces 121_L, 121_R is provided with a hole 124 near the rear end, the hole 124 being located on a straight line extending left and right.

[0047] The first holding member 106 according to this embodiment is attached to the seat plate 105 with the support plate portion 122 inclined at about 8 degrees so that the L-shaped portion 123 extends upward and then faces rearward. In this way, the holding portion 120 of the first holding member 106 serves as a front end holding portion and surrounds the front end, the front surface, and part of the back surface of the solar power generation panel 101. As a result, the first holding member 106 can hold the solar power generation panel 101 so as to limit the range of movement of the front end of the solar power generation panel 101 in the forward and up-down directions.

[0048] In addition, in the first retaining member 106 according to the present embodiment, the two mounting pieces 121_L, 121_R are disposed between the left side plate portion 111_L and the right side plate portion 111_R of the seat plate 105. An L-shaped pin 125 shown in Fig. 10 is attached in a state in which it penetrates through holes 124 provided in each of the left and right mounting pieces 121_L, 121_R and holes 113 provided in the vicinity of the front end portions of each of the left side plate portion 111_L and the right side plate portion 111_R.

[0049] Here, as shown in FIG. 10, L-shaped pin 125 has a shape in which a rod-shaped member with a circular cross section is bent into an L shape, and has a straight rod-shaped portion 126, a locking portion 127 extending from one end of rod-shaped portion 126 at approximately a right angle to rod-shaped portion 126, and a male thread portion 128 provided in the vicinity of the other end of rod-shaped portion 126.

[0050] By inserting the rod-shaped portion 126 of the L-shaped pin 125 into the holes 124 and 113, the first retaining member 106 can be attached to the front end portion of the seat plate 105 so as to be rotatable about an axis in the left-right direction and so as to be detachable.

[0051] Furthermore, in a state where the first holding member 106 is attached to the seat plate 105, a nut is attached to the male thread portion 128 of the L-shaped pin 125. As a result, the L-shaped pin 125 is caught by the left side plate portion 111_L and the right side plate portion 111_R and stopped by the nut and the locking portion 127 so as not to fall off. Therefore, it is possible to prevent the L-shaped pin 125 from coming off unintentionally by the user and the first holding member 106 from moving away from the seat plate 105.

[0052] The cross-sectional shape of the L-shaped pin 125 may be a polygon or the like as appropriate.

[0053] The second holding member 108 is a member attached to the tip of the inclination angle defining member 107 in order to hold the photovoltaic panel 101, similarly to the first holding member 106. The second holding member 108 is attached to the tip of the inclination angle defining member 107 so as to be rotatable about an axis in the left-right direction and so as to be detachable.

[0054] Second holding member 108 differs from first holding member 106 not only in the location where it is attached but also in the orientation in which it is attached, but its structure is similar to that of first holding member 106 described above (see FIG. 8).

[0055] In detail, the second holding member 108 is attached to the tip end of the inclination angle defining member 107 with its holding portion 120 facing the holding portion 120 of the first holding member 106 across the solar power generation panel 101. This allows the holding portion 120 of the second holding member 108 to function as a rear end holding portion and surround the rear end, front surface, and part of the rear surface of the solar power generation panel 101. As a result, the second holding member 108 can hold the solar power generation panel 101 so as to limit the range of movement of the rear end of the solar power generation panel 101 in the rearward and up-down directions.

[0056] As shown in FIGS. 1 to 6, the cover 104 has a plurality of front plates 129_a to 129_c, a plurality of right side plates 130_a and 130_b, a plurality of left side plates 131_a and 131_b, a plurality of rear plates 132_a to 132_c, and a plurality of connecting plates 133_a to 133_c.

[0057] By using a material that is resistant to rust, such as stainless steel, for the material of the members 129-133 constituting the cover 104, it is possible to prevent damage due to rust to objects that have been placed on the installation surface G in advance. Note that the material of the members 129-133 constituting the cover 104 is not limited to stainless steel, and may be appropriately selected from metals, resins, and the like.

[0058] The front panels 129_a to 129_c are provided corresponding to the solar power generation panels 101_a to 101_c arranged on the left and right sides in the front row, respectively. The front panels 129_a to 129_c close the gaps between the front ends of the solar power generation panels 101_a to 101_c corresponding to each of them and the installation surface G.

[0059] In this embodiment, the multiple front panels 129_a to 129_c are fixed to base plates 105 constituting each of the support legs 103 of the corresponding photovoltaic power generation panels 101_a to 101_c. For example, each of the multiple front panels 129_a to 129_c has a hole, and the multiple front panels 129_a to 129_c are fixed by fitting a bolt B and a nut N inserted into the hole and a hole 112 provided in a front panel portion 110 of the base plate 105.

[0060] In this embodiment, each of the front panels 129_a to 129_c includes an overlapping portion 134 for overlapping and fixing the adjacent front panels 129_a and 129_b, and 129_b and 129_c to each other. This allows the front panels 129_a to 129_c to easily determine their respective left-right positions.

[0061] The right side panels 130_a, 130_b are provided corresponding to the solar power generation panels 101_c, 101_f arranged in the front-rear direction in the rightmost row, respectively. The right side panels 130_a, 130_b close the gaps between the right ends of the solar power generation panels 101_c, 101_f to which they are respectively associated and the installation surface G.

[0062] 1 and 2, in this embodiment, the front right side plate 130_a has holes communicating with holes provided in the front plate 129_c and the connecting plate 133_c, and is fixed by fitting a bolt B and a nut N inserted into these communicating holes. In this way, the front right side plate 130_a is fixed so as to close a gap formed between the right end of the solar power generation panel 101_c, the front plate 129_c, the installation surface G, and the connecting plate 133_c.

[0063] The rear right side plate 130_b has holes that communicate with holes provided in the connecting plate 133_c and the rear plate 132_c, and is fixed by fitting a bolt B and a nut N inserted into these communicating holes. In this way, the rear right side plate 130_b is fixed so as to close a gap formed between the right end of the solar power generation panel 101_f, the connecting plate 133_c, the installation surface G, and the rear plate 132_c.

[0064] The left side plates 131_a and 131_b are provided on the cover 104 symmetrically with the right side plates 130_a and 130_b.

[0065] That is, the left side panels 131_a, 131_b are provided corresponding to the solar power generation panels 101_a, 101_d arranged in the leftmost row in front and rear, respectively. The left side panels 131_a, 131_b close the gaps between the left ends of the solar power generation panels 101_a, 101_d to which they are respectively associated and the installation surface G.

[0066] In this embodiment, the front left side plate 131_a has holes communicating with holes provided in the front plate 129_a and the connecting plate 133_a, and is fixed by fitting a bolt B and a nut N inserted into these communicating holes. In this way, the front left side plate 131_a is fixed so as to close a gap formed between the left end of the solar panel 101_a, the front plate 129_a, the installation surface G, and the connecting plate 133_a.

[0067] The rear left side plate 131_b has holes communicating with holes provided in the connecting plate 133_a and the rear plate 132_a, and is fixed by fitting a bolt B and a nut N inserted into these communicating holes. In this way, the rear left side plate 131_b is fixed so as to close a gap formed between the left end of the solar power generation panel 101_d, the connecting plate 133_a, the installation surface G, and the rear plate 132_a.

[0068] The multiple rear panels 132_a to 132_c are provided corresponding to the solar power generation panels 101_d to 101_f arranged on the left and right sides in the last row, respectively. The multiple rear panels 132_a to 132_c close the gaps between the rear ends of the solar power generation panels 101_d to 101_f to which they are respectively associated and the installation surface G.

[0069] In this embodiment, the multiple rear plates 132_a to 132_c are fixed to inclination angle defining members 107 constituting each of the support legs 103 of the corresponding photovoltaic power generation panels 101_d to 101_f. For example, each of the multiple rear plates 132_a to 132_c has a hole, and the multiple rear plates 132_a to 132_c are fixed by fitting a bolt B and a nut N inserted into this hole and a hole 117 provided in a back plate portion 115 of the inclination angle defining member 107.

[0070] In this embodiment, each of the rear panels 132_a to 132_c includes an overlapping portion 135 for overlapping and fixing the adjacent rear panels 132_a and 132_b, and 132_b and 132_c to each other. This makes it easy to determine the left-right positions of the rear panels 132_a to 132_c relative to each other.

[0071] The multiple connecting plates 133_a to 133_c are provided corresponding to each pair of solar power generation panels 101_a and 101_d, 101_b and 101_e, and 101_c and 101_f arranged in front and behind. The multiple connecting plates 133_a to 133_c connect the solar power generation panels 101_a and 101_d, 101_b and 101_e, and 101_c and 101_f that respectively constitute the corresponding pairs.

[0072] Further, the multiple connecting plates 133_a to 133_c close the gaps between the installation surface G and the rear and front ends of the front and rear photovoltaic panels 101_a and 101_d, 101_b and 101_e, and 101_c and 101_f that respectively form corresponding pairs.

[0073] That is, in this embodiment, for example, the solar power generation panels associated with the multiple connecting plates 133_a are the solar power generation panels 101_a and 101_d arranged in front and behind. The multiple connecting plates 133_a close the gap between the rear end of the front solar power generation panel 101_a of these associated solar panels and the installation surface G. The multiple connecting plates 133_a also close the gap between the front end of the rear solar power generation panel 101_d of these associated solar panels and the installation surface G.

[0074] In this regard, the connecting plate 133_b has a configuration in which the solar power generation panels 101_a and 101_d are replaced with solar power generation panels 101_b and 101_e, respectively, and closes the gap between the rear end of the solar power generation panel 101_b and the installation surface G, and closes the gap between the front end of the solar power generation panel 101_e and the installation surface G. In addition, the connecting plate 133_c has a configuration in which the solar power generation panels 101_a and 101_d are replaced with solar power generation panels 101_c and 101_f, respectively, and closes the gap between the rear end of the solar power generation panel 101_c and the installation surface G, and closes the gap between the front end of the solar power generation panel 101_f and the installation surface G.

[0075] In this embodiment, the multiple connecting plates 133_a to 133_c are fixed to the inclination angle determining members 107 and seat plates 105 that constitute each of the support legs 103 of the front and rear solar power generation panels 101_a and 101_d, 101_b and 101_e, and 101_c and 101_f that form corresponding pairs.

[0076] For example, the multiple connecting plates 133_a to 133_c are fixed to the inclination angle defining members 107 constituting each of the support legs 103 of the front photovoltaic power generation panels 101_a to 101_c of the corresponding pairs. For example, each of the multiple connecting plates 133_a to 133_c has a hole, and is fixed by fitting a bolt B and a nut N inserted into this hole and a hole 117 provided in the back plate portion 115 of the inclination angle defining member 107.

[0077] Furthermore, for example, the multiple connecting plates 133_a to 133_c are fixed to the seat plates 105 constituting the respective support legs 103 of the rear photovoltaic power generation panels 101_a to 101_c of the respective associated pairs. For example, each of the multiple connecting plates 133_a to 133_c has a hole, and is fixed by fitting a bolt B and a nut N inserted into this hole and a hole 112 provided in the front plate portion 110 of the seat plate 105.

[0078] Furthermore, in this embodiment, each of the multiple connecting plates 133_a to 133_c includes an overlapping portion 136 for overlapping and fixing the adjacent connecting plates 133_a and 133_b, and 133_b and 133_c to each other, so that the multiple connecting plates 133_a to 133_c can easily determine their respective left-right positions.

[0079] So far, the configuration of the solar power generation device 100 according to the first embodiment of the present invention has been described. From here, a method for installing the solar power generation device 100 according to the present embodiment will be described.

[0080] 11 is a diagram showing a flow of steps included in a method for installing the solar power generation device 100. Various members constituting the solar power generation device 100, i.e., the multiple solar power generation panels 101_a to 101_f, members constituting the twelve support legs 103, and members constituting the cover 104, are prepared and transported to an installation surface G (step 1).

[0081] The members constituting the support leg 103 include a seat plate 105, a first holding member 106, an inclination angle regulating member 107, a second holding member 108, and bolts B and nuts N for fixing these members. The members constituting the cover 104 include front plates 129_a to 129_c, right side plates 130_a, 130_b, left side plates 131_a, 131_b, rear plates 132_a to 132_c, connecting plates 133_a to 133_c, and bolts B and nuts N for fixing these members.

[0082] For example, when the installation surface G is the surface of a flat roof, it is generally necessary to carry various members constituting the solar power generation device 100 to the rooftop of the building. The solar power generation panel 101 according to this embodiment has the size and weight described above, and therefore can be easily carried using normal elevators and stairs used by residents. Furthermore, the members constituting the support legs 103 and the cover 104 are also sized to correspond to the solar power generation panel 101 and are made of a lightweight material such as stainless steel, and therefore can be easily carried using normal elevators and stairs used by residents.

[0083] Using the members carried in step 1, a pair of support legs 103 are attached to each of the photovoltaic panels 101 (step 2).

[0084] The process of attaching the support legs 103 is detailed below.

[0085] The base end of the inclination angle regulating member 107 having a length is fixed to the rear end of the seat plate 105 with a bolt B and a nut N. After the first holding member 106 is attached to the front end of the seat plate 105 with an L-shaped pin 125, a nut is fitted onto the male thread portion 128 of the L-shaped pin 125. As a result, the first holding member 106 is attached near the front end of the seat plate 105 so as to be rotatable around the L-shaped pin 125.

[0086] The front end of the solar power generation panel 101 is inserted into the holding portion 120 of the first holding member 106, thereby causing the front end of the solar power generation panel 101 to be held by the first holding member 106. The rear end of the solar power generation panel 101 located behind the first holding member 106 is inserted into the holding portion 120 of the second holding member 108, thereby causing the rear end of the solar power generation panel 101 to be held by the second holding member 108. Then, the second holding member 108 is attached to the tip of the inclination angle regulating member 107 with an L-shaped pin 125, and then a nut is fitted onto the male thread portion 128 of the L-shaped pin 125.

[0087] As a result, the front end and rear end of the solar power generation panel 101 are held by the respective holding portions 120 of the first holding member 106 and the second holding member 108 arranged side by side in the front-to-rear direction, thereby attaching the support leg 103 to the solar power generation panel 101. In a similar manner, the other support leg 103 is attached to the solar power generation panel 101. By repeating this, a pair of support legs 103 can be attached to each solar power generation panel 101.

[0088] The method of attaching the support legs 103 to the solar panel 101 described here is merely an example and may be changed as appropriate.

[0089] A reference position O is determined on the installation surface G (step 3). The reference position O is a reference position when arranging the solar power generation panel 101, and is used for positioning the solar power generation panel 101 arranged at an edge, such as the front left, front right, rear left, or rear right. The reference position O according to this embodiment determines the position of the solar power generation panel 101 arranged at the front left (see FIG. 12).

[0090] Using the reference position O, the photovoltaic panel 101 with the support legs 103 is placed (step 4).

[0091] 12, a straight line L1 extending to the right with reference to the reference position O as a reference, and a straight line L2 extending backward with reference to the reference position O as a reference are drawn. These straight lines L1 and L2 are not necessary once the solar power generation panel 101 is installed, so they may be drawn with something that is easy to remove, such as chalk that will naturally disappear with rain. First, the solar power generation panel 101_a is positioned so that the front left corner coincides with the reference position O, and the front end and left end are aligned with the straight lines L1 and L2.

[0092] 13, the solar power generation panel 101_b is arranged next to the right of the solar power generation panel 101_a so that the front end portion is aligned along the straight line L1. Subsequently, the solar power generation panel 101_c is arranged next to the right of the solar power generation panel 101_b so that the front end portion is aligned along the straight line L1.

[0093] Two measurement assistants 137 as shown in FIG. 14 are prepared. As shown in FIG. 15, the measurement assistants 137 are arranged in a predetermined direction so as to contact the rear ends of the support legs 103 of the photovoltaic power generation panel 101_a. The photovoltaic power generation panel 101_d is arranged so that the left side portion is along the straight line L2 and the front ends of the support legs 103 are in contact with the corresponding measurement assistants 137. In this way, by using the measurement assistants 137, the photovoltaic power generation panels 101_a and 101_d arranged in front and behind can be easily arranged at a predetermined interval. It is to be noted that, for example, only one measurement assistant 137 may be used here to adjust the front and rear positions of the support legs 103 one by one.

[0094] The photovoltaic power generation panel 101_e is similarly arranged at a predetermined distance from the photovoltaic power generation panel 101_b to the right of the photovoltaic power generation panel 101_d using the measurement assistant tool 137. Then, the photovoltaic power generation panel 101_f is similarly arranged at a predetermined distance from the photovoltaic power generation panel 101_c to the right of the photovoltaic power generation panel 101_e using the measurement assistant tool 137. In this way, the photovoltaic power generation panels 101_a to 101_f with the support legs 103 are arranged (see FIG. 2, for example). At this time, each time each of the photovoltaic power generation panels 101_a to 101_f is arranged, the bonding area of ​​the seat plate 105 of the support leg 103 attached to each of the photovoltaic power generation panels 101_a to 101_f may be bonded to the ground surface G.

[0095] It should be noted that the method of arranging the solar panel 101 with the support legs 103 described here is merely one example and may be changed as appropriate.

[0096] A cover is attached to close the gap between the peripheral edge of the arranged photovoltaic panels 101_a to 101_f with the support legs 103 and the installation surface G (step 5).

[0097] For example, first, the front plates 129_a to 129_c are attached in order from the left, the connecting plates 133_a to 133_c are attached in order from the left, and the rear plates 132_a to 132_c are attached in order from the left. At this time, the overlapping portions of each are also fixed in an overlapping state. The left side plates 131_a and 131_b and the right side plates 130_a and 130_b are attached. In this way, the cover 104 is attached.

[0098] In this way, the solar power generation device 100 according to this embodiment is installed.

[0099] The photovoltaic panel stand 102 according to this embodiment includes a cover 104 that closes the gap between the installation surface G and the peripheral portion of the multiple photovoltaic panels 101 arranged side by side on the installation surface G. Such a cover 104 makes it difficult for wind to get under the photovoltaic panels 101. As a result, when the wind blows, the photovoltaic panels 101 receive a positive pressure that presses them against the installation surface G, making them less likely to be blown away. This eliminates the need to provide a concrete foundation or the like, making it possible to easily install the photovoltaic panels on the installation surface G, such as a flat roof.

[0100] The members constituting each of the support legs 103 according to this embodiment are common, and therefore it is easy to assemble each of the support legs 103. Furthermore, the members constituting the cover 104 are generally the same in shape and size, and even if the arrangement of the photovoltaic power generation panels 101 is changed in various ways, by repeatedly connecting these members, it is possible to cover the gaps between the peripheral portions of the multiple photovoltaic power generation panels 101 and the installation surface G. Therefore, it becomes possible to easily install the photovoltaic power generation panel stand 102.

[0101] The multiple front plates 129_a to 129_c, multiple rear plates 132_a to 132_c, and multiple connecting plates 133_a to 133_c that constitute the cover 104 in this embodiment are not simply fixed to the support leg 103, but are also fixed to each other by overlapping portions 134 to 136.

[0102] This allows the cover 104 to be integrated into a planar shape, so that even if the cover 104 is installed on an installation surface G that is easily exposed to wind, such as a flat roof, wind is less likely to get under the photovoltaic panel 101. As a result, when the wind blows, the photovoltaic panel 101 is subjected to a positive pressure that presses the photovoltaic panel 101 against the installation surface G, making it even less likely to be blown away.

[0103] In this embodiment, the multiple right side plates 130_a, 130_b and the multiple left side plates 131_a, 131_b are each fixed to the face plates 129_a to 129_c and the connecting plates 133_a to 133_c, or to the rear face plates 132_a to 132_c and the connecting plates 133_a to 133_c.

[0104] This allows the cover 104 to be integrated as a whole, and furthermore, makes it difficult for wind to get under the solar power generation panel 101. As a result, when the wind blows, the solar power generation panel 101 receives a positive pressure that presses the solar power generation panel 101 against the installation surface G as a whole, making it even more difficult for the solar power generation panel 101 to be blown away.

[0105] In the solar panel stand 102 according to this embodiment, the first holding member 106 that holds the front end portion, etc., of the solar panel 101, and the second holding member 108 that holds the rear end portion, etc., are both attached by an L-shaped pin 125. This allows the solar panel 101 to be easily removed by removing the nut of the L-shaped pin 125, and allows the panel 101 to be rotated with the L-shaped pin 125 inserted.

[0106] Therefore, if the front L-shaped pin 125 is removed, the solar power panel 101 can be lifted by rotating it around the rear L-shaped pin 125, and if the rear L-shaped pin 125 is removed, the solar power panel 101 can be lifted by rotating it around the front L-shaped pin 125. That is, with the solar power panel stand 102 according to this embodiment, the solar power panel 101 can be easily lifted from either the front or rear.

[0107] Usually, the solar power generation panel 101 requires work on the rear side thereof for connecting electrical wiring, maintenance, etc. According to this embodiment, the solar power generation panel 101 can be easily lifted from either the front or the rear side depending on the situation of the installation location. Therefore, it becomes possible to easily perform work on the rear side of the solar power generation panel 101, such as connecting electrical wiring and maintenance.

[0108] (Embodiment 2) In the first embodiment, an example has been described in which the solar panels 101_a and 101_d, 101_b and 101_e, and 101_c and 101_f arranged in front and rear are spaced apart from each other by a predetermined distance and inclined in the same direction. In the present embodiment, an example will be described in which a plurality of solar panels 201_a to 201_l are arranged adjacent to each other not only in the left-right direction but also in the front-rear direction, as shown in Fig. 16.

[0109] As shown in Fig. 16 which is a plan view and Fig. 17 which is an enlarged view of a side cross section, a solar power generation device 200 according to this embodiment includes a plurality of solar power generation panels 201_a to 201_l and a solar power generation panel stand 202. The solar power generation panel stand 202 includes a plurality of support legs 103 and a cover 204 similar to those in the first embodiment.

[0110] Each of the multiple photovoltaic panels 201_a to 201_l according to the present embodiment differs from that of the first embodiment in the orientation and number of panels, but may otherwise be similar to the photovoltaic panel 101 according to the first embodiment. The support legs 103 may be attached to each of the photovoltaic panels 201_a to 201_l in pairs, similar to the first embodiment.

[0111] The solar power generation panels 201_a to 201_c and 201_g to 201_i according to the present embodiment are disposed with an inclination of approximately 8 degrees toward the lower front, similar to the solar power generation panels 101_a to 101_c according to embodiment 1. In contrast, the solar power generation panels 201_d to 201_f and 201_j to 201_l are disposed with an inclination of approximately 8 degrees toward the lower rear in this embodiment, in a direction different from that of the solar power generation panels 101_d to 101_f according to embodiment 1.

[0112] 17, the solar power generation panels 201_a to 201_c and the solar power generation panels 201_d to 201_f are arranged such that the inclination angle defining members 107 of the support legs 103 are adjacent to each other. Moreover, the solar power generation panels 201_d to 201_f and the solar power generation panels 201_g to 201_i are arranged such that the front ends of the inclination angle defining members 107 of the support legs 103 are adjacent to each other. Moreover, the solar power generation panels 201_g to 201_i and the solar power generation panels 201_j to 201_l are arranged such that the inclination angle defining members 107 of the support legs 103 are adjacent to each other.

[0113] The cover 204 closes gaps between the peripheral edges of the multiple photovoltaic panels 201_a-201_l with support legs 103 arranged side by side on the installation surface G and the installation surface G. The cover 204 according to the present embodiment has multiple front plates 129_a-129_c similar to those in the first embodiment, and multiple right side plates 230, multiple left side plates 231, multiple rear plates 232_a-232_c, and multiple connecting plates 233_a-233_c different from those in the first embodiment.

[0114] Each of the right side panels 230 generally forms an isosceles triangle when viewed from the right. The right side panels 230 are arranged in correspondence with each pair of two solar panels 201_c and 201_f, and 201_i and 201_l arranged in front and rear with the inclination angle defining members 107 of the support legs 103 adjacent to each other.

[0115] Each of the multiple left side panels 231 also forms a substantially isosceles triangle when viewed from the left, similar to the right side panel 230. The left side panel 231 is disposed in correspondence with each pair of photovoltaic panels 201_a and 201_d, and 201_g and 201_j arranged in front and behind with the inclination angle defining members 107 of the support legs 103 adjacent to each other.

[0116] The rear panels 232_a to 232_c have the same configuration as the front panels 129_a to 129_c, respectively, and are provided in a symmetrical manner. Thus, like the front panels 129_a to 129_c, the rear panels 232_a to 232_c include overlapping portions 235 for overlapping and fixing the adjacent front panels 232_a and 232_b, and 232_b and 232_c to each other.

[0117] The multiple connecting plates 233_a to 233_c connect the solar power generation panels 201_d and 201_g, 201_e and 201_h, and 201_f and 201_i arranged in front and rear such that the front ends of the inclination angle regulating members 107 of the support legs 103 are adjacent to each other. Each of the multiple connecting plates 233_a to 233_c has a different shape when viewed from the side from the multiple connecting plates 133_a to 133_c according to the first embodiment (see FIGS. 3 and 17), but is otherwise configured in a similar manner. Therefore, for example, the multiple connecting plates 233_a to 233_c include overlapping portions 236 for overlapping and fixing the adjacent connecting plates 233_a and 233_b, 233_b and 233_c to each other, similar to the multiple connecting plates 133_a to 133_c according to the first embodiment.

[0118] According to this embodiment, since the inclination angle regulating member 107 of the support leg 103 extends almost straight up, the support leg 103 does not protrude backward, and as a result, the multiple photovoltaic power generation panels 201_a to 201_l can be arranged adjacent to each other in the front-rear and left-right directions. This allows the photovoltaic power generation panels 201_a to 201_l to be arranged more densely than in the first embodiment, where the photovoltaic power generation panels 201_a to 201_l are arranged with gaps in the front-rear direction, that is, when the area of ​​the installation surface G is the same, more photovoltaic power generation panels 201_a to 201_l can be arranged than in the first embodiment. As a result, even if the area of ​​the installation surface G is the same, it is possible to obtain more generated power.

[0119] Although the embodiment and the modified examples of the present invention have been described above, the present invention is not limited to these. For example, the present invention also includes a form in which some or all of the embodiment and the modified examples described so far are appropriately combined, and a form in which the form is appropriately modified.
