DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following, similar elements in all drawings will be designated by the same reference numerals, and duplicate explanations will be omitted. Furthermore, in the description below, previously described reference numerals will be used as necessary.

[0013] Fig. 1 is a front view showing a bihedral photovoltaic power generation system 10 according to a first embodiment of the present invention. Fig. 2 is a perspective view showing a bihedral photovoltaic power generation system 10 according to the first embodiment of the present invention.

[0014] A bihedral photovoltaic power generation system 10 according to a first embodiment of the present invention is a system capable of generating electricity by receiving sunlight from various directions. The bihedral photovoltaic power generation system 10 includes a first solar panel unit 12, a second solar panel unit 14, and a support unit 16.

[0015] The first solar panel unit 12 is a solar panel installed at a predetermined inclination angle α. The first solar panel unit 12 is configured with a plurality of solar cells lined up, and has the function of generating electricity by utilizing the photovoltaic effect using sunlight. Various solar cell configurations are considered, and for example, silicon-based, compound-based, organic-based, quantum dot-based, etc. can be used. In this example, a silicon-based solar cell is configured to be able to emit light not only from the front surface but also from the back surface.

[0016] Here, the predetermined angle α is preferably set to a value between 0° and 35°, and is most preferably set to 35°.

[0017] The second solar panel unit 14 is a solar panel installed at a predetermined angle α so as to face the first solar panel unit 12. Similar to the first solar panel unit 12, the second solar panel unit 14 is configured with multiple solar cells lined up and has the function of generating electricity by utilizing the photovoltaic effect using sunlight. Various solar cell configurations are considered, including silicon-based, compound-based, organic-based, and quantum dot-based solar cells. In this example, a silicon-based solar cell is used, which can emit light not only from the front surface but also from the back surface.

[0018] The support column 16 has an isosceles triangular support portion for supporting the first solar panel portion 12 and the second solar panel portion 14. As shown in Fig. 1, when the dihedral solar power generation system 10 is viewed from the front, it has an isosceles triangular shape, and these triangular support members are arranged in a row in the depth direction and the width direction as shown in Fig. 2.

[0019] The support column 16 has a truss structure that is symmetrical in two triangular regions separated by a perpendicular line drawn from the apex to the base of an isosceles triangle of the support column. Specifically, as shown in Fig. 1, the first truss is a triangle shape formed by support members 16a and 16b corresponding to the equilateral parts for mounting the first solar panel unit 12 and the second solar panel unit 14, and support member 16c corresponding to the base.

[0020] As shown in Figure 1, the first truss has support members 17a and 17b installed as legs at both ends of the bottom support member 16c, and support members 17c and 17d extending downward from the support members 16a and 16b at the center and also functioning as legs.

[0021] Support members 16a and 16b are connected at connecting portion 19a at the apex of the triangle. Support members 17a and 17b are connected at connecting portions 19f and 19g at the intersections of support members 16a, 16b and support member 16c.

[0022] The support members 17c and 17d are connected to the support members 16a and 16b at connecting portions 19b and 19c, and the support members 17c and 17d are connected to the support member 16c at connecting portions 19h and 19i.

[0023] Furthermore, support member 18a is provided on the left side of the two triangular regions so as to bisect the triangle formed by support members 16a, 16c, and 17c from the vertex (connecting portion 19h) toward the base. Support member 18a and support member 16a are connected at connecting portion 19d.

[0024] Support member 18b is provided on the right side of the two triangular regions, dividing the triangle formed by support members 16b, 16c, and 17d in half from the vertex (connecting portion 19i) toward the base. Support member 18b and support member 16b are connected at connecting portion 19e.

[0025] The second truss is a structure that forms the left triangular shape of the two triangular regions shown in Figure 1, and is formed by support members 16a, 17c, and 18a. The third truss is a structure that forms the left triangular shape of the two triangular regions, and is formed by support members 16a, 16c, and 18a.

[0026] The fourth truss is a structure that forms the right triangular shape of the two triangular regions shown in Figure 1, and is formed by support members 16b, 17d, and 18b. The fifth truss is a structure that forms the right triangular shape of the two triangular regions, and is formed by support members 16b, 16c, and 18b.

[0027] The bifacial photovoltaic power generation system 10 of the first embodiment according to the present invention is preferably installed in areas with little snowfall, such as a meadow where grass is harvested to provide livestock feed or compost.

[0028] When installing the solar panels on grassland, it is preferable to graze sheep on the grassland. This reduces maintenance costs by removing weeds that can reduce the power generation efficiency of solar panels. In addition, organic farming is possible using compost such as sheep droppings.

[0029] The advantage of grassland is that it does not require cutting down trees or uproots, it allows for environmentally friendly renewable energy, and it can be used for agriculture (grazing), livestock farming (grazing), and power generation, and it can generate revenue from these businesses.

[0030] Next, a bihedral photovoltaic power generation system 10a according to a second embodiment of the present invention will be described. Figure 3 is a front view showing a bihedral photovoltaic power generation system 10a according to the second embodiment of the present invention. The only difference between bihedral photovoltaic power generation system 10a and bihedral photovoltaic power generation system 10 is the predetermined angle α, and the rest is the same, so the following description will focus on the differences.

[0031] The predetermined angle α is preferably set to a value between 0° and 35°, and in this example, it is set to 15°.

[0032] Like bifacial solar power generation system 10, bifacial solar power generation system 10a of the second embodiment of the present invention is preferably installed in areas with little snow, and more preferably, installed in grassland, and will achieve the same effects as bifacial solar power generation system 10.

[0033] Next, a bihedral photovoltaic power generation system 10b according to a third embodiment of the present invention will be described. Figure 4 is a front view of bihedral photovoltaic power generation system 10b according to the third embodiment of the present invention. The only difference between bihedral photovoltaic power generation system 10b and bihedral photovoltaic power generation system 10 is the predetermined angle α, and the rest is the same, so the following description will focus on the differences.

[0034] The predetermined angle α is preferably set to 35° to 50°, and in this example, it is set to 40°. The ideal installation angle for solar panels is a slight inclination of 30°. However, it is important to note that latitudes vary depending on the region within Japan. For example, Okinawa is at 27° north latitude, while Hokkaido is at 45° north latitude. As a rough guide, it is preferable to set the angle to 18° when installing in Okinawa Prefecture, and 35° when installing in Hokkaido.

[0035] Here, the bifacial photovoltaic power generation system 10b of the third embodiment according to the present invention is preferably installed in a region with heavy snowfall, for example, Hokkaido, where temperatures are low throughout the year and where photovoltaic power generation can be performed at temperatures close to 25°C, the temperature at which photovoltaic power generation is said to be at its best, even in summer.

[0036] Eastern Hokkaido is located at a high latitude, receives a lot of sunlight, and is the easternmost region in Japan in terms of longitude, allowing for the fastest charging times in Japan. Furthermore, the low temperatures allow for efficient power generation. The bifacial solar power generation system 10b is preferably installed in a heavy snowfall area. Here, a "heavy snowfall area" refers to an area that receives a large amount of snowfall in winter, and in Japan's legal system, refers to an area designated specifically under the Act on Special Measures for Heavy Snowfall Areas.

[0037] Next, a third embodiment of a bihedral photovoltaic power generation system 10c according to the present invention will be described. Fig. 5 is a front view of a fourth embodiment of a bihedral photovoltaic power generation system 10c according to the present invention. The only difference between bihedral photovoltaic power generation system 10c and bihedral photovoltaic power generation system 10 is the predetermined angle α, and the rest is the same, so the following description will focus on the differences.

[0038] The predetermined angle α is preferably set to 45° to 70°, and in this example it is set to 70°. In areas with particularly heavy snowfall, it is necessary to provide a certain slope so that snow can slide off even if it accumulates on the solar panel.

[0039] The bifacial solar power generation system 10c of the third embodiment according to the present invention is preferably installed in a particularly heavy snowfall area, for example, Hokkaido. Here, the "particularly heavy snowfall area" refers to a part of a prefecture designated as a heavy snowfall area in accordance with the standards set by the Minister of Land, Infrastructure, Transport and Tourism, the Minister of Internal Affairs and Communications, and the Minister of Agriculture, Forestry and Fisheries after a resolution of the National Land Council, for an area where snowfall is particularly heavy and where the lives of residents are significantly affected by long-term suspension of automobile traffic due to snowfall.

[0040] All of the embodiments of the bifacial solar power generation systems 10, 10a, 10b, and 10c according to the present invention are capable of generating power on two surfaces, the first solar panel unit 12 and the second solar panel unit 14, which are arranged on the equilateral sides of an isosceles triangle, and therefore have the remarkable advantage of being able to ensure sufficient power generation even when the position of the sun changes due to the movement of the sun.

[0041] In all of the embodiments of the bifacial photovoltaic power generation systems 10, 10a, 10b, and 10c according to the present invention, the support poles 16 all have a truss structure, which has the remarkable advantage of allowing for stable installation that is resistant to snow accumulation and crosswinds.

[0042] FIG. 6 is a diagram showing the state of a conventionally used monofacial solar panel unit 8 in bifacial solar power generation systems 10, 10a, 10b, and 10c of all the embodiments of the present invention when subjected to a strong crosswind.

[0043] FIG. 7 is a diagram showing that all of the dihedral photovoltaic power generation systems 10, 10a, 10b, and 10c according to the present invention have a structure that is resistant to crosswinds.

[0044] Here, the fact that bihedral solar power generation systems 10, 10a, 10b, and 10c can be installed stably and with high resistance to crosswinds will be described using Figures 6 and 7. While Figure 7 uses bihedral solar power generation system 10b for explanation, bihedral solar power generation systems 10, 10a, and 10c also provide similar advantages.

[0045] As shown in Figure 6, a conventional single-sided solar panel unit 8 includes a solar panel 8a and a support member 8b. In a single-sided solar panel unit 8, crosswinds blowing from the front surface of the solar panel 8a flow up and down along the panel surface, reducing the risk of the panel collapsing. However, as shown in Figure 6, when the soil is muddy, especially after rain, there is a risk that the wind blowing up from the back of the solar panel 8a may cause the entire panel to collapse, along with the support member 8b.

[0046] In contrast, as shown in Figure 7, the bifacial solar power generation system 10b has five truss structures, and therefore the structure supporting the first solar panel unit 12 and the second solar panel unit 14 is distributed from the support pillars, resulting in the strongest truss structure, which has the advantage of increasing the stability and strength of the panels.

[0047] The support column 16 is equipped with the first solar panel section 12 and the second solar panel section 14, and has an isosceles triangular roof structure, which allows crosswinds from any direction to flow along the panel surface, reducing the risk of collapse. Furthermore, because the system can be stabilized even with shallow support columns, installation costs can be kept low.

[0048] Next, a case where the bihedral photovoltaic power generation system 10b is installed in a heavy snowfall area will be described. Figure 8 is a diagram showing a bihedral photovoltaic power generation system 10b according to a third embodiment of the present invention installed in a heavy snowfall and strong wind area.

[0049] As shown in Fig. 8, bihedral photovoltaic power generation system 10b is installed so that the surface of first solar panel unit 12 faces west and the surface of second solar panel unit 14 faces east. As shown in Fig. 8, bihedral photovoltaic power generation systems 10b are arranged side by side on both ends of the installation area in the east-west direction.

[0050] The monofacial solar panel unit 8 is then installed between the bifacial solar power generation systems 10b, which are arranged in two separate areas, east and west, with the surfaces of the solar panels 8a facing south. The monofacial solar panel units 8 are aligned with a predetermined spacing in the direction of the solar panels. The solar panels 8a of the monofacial solar panel unit 8 are installed at a predetermined inclination angle β.

[0051] With this solar panel arrangement, the bifacial solar power generation system 10b has solar panels facing east-west, which increases the amount of power generated by sunlight in the morning and evening, while the single-facial solar panel unit 8 facing south is located in the center, which increases the amount of power generated during the day. This allows for stable power generation from morning to evening. Furthermore, there is no peak cut due to overloading, so there is no power loss, and power generation efficiency can be increased without putting a strain on the power transmission and distribution system, which has the advantage of not putting a strain on the power transmission lines.

[0052] Furthermore, since the bifacial photovoltaic power generation system 10b can generate power from light incident on both sides, it can also generate power from light reflected off snow.

[0053] Next, a case where a bihedral photovoltaic power generation system 10c is installed in a particularly heavy snowfall area will be described. Fig. 9 is a diagram showing a bihedral photovoltaic power generation system 10c, which is a modified example of the bihedral photovoltaic power generation system 10 of the fourth embodiment of the present invention, installed in a particularly heavy snowfall and strong wind area.

[0054] As shown in Figure 9, the bihedral solar power generation system 10c is installed so that the surface of the first solar panel unit 12 faces west and the surface of the second solar panel unit 14 faces east. As shown in Figure 9, multiple bihedral solar power generation systems 10c are aligned and arranged at predetermined intervals throughout the installation area.

[0055] This solar panel arrangement allows the solar panels to face east-west, increasing the amount of power generated in the morning and evening. Furthermore, the tilt angle of the bifacial solar power generation system 10c is set to 70°, which has the advantage of minimizing the impact of snow in particularly heavy snowfall areas.

[0056] Next, a solar power generation system 20 with a creature-growing function that utilizes bihedral solar power generation system 10a will be described. Fig. 10 is a front view of solar power generation system 20 with a creature-growing function. Fig. 11 is a perspective view of solar power generation system 20 with a creature-growing function. Here, solar power generation system 20 with a creature-growing function will be described as a system that utilizes bihedral solar power generation system 10a, but similar effects can also be achieved with bihedral solar power generation systems 10, 10b, and 10c.

[0057] The solar power generation system 20 with a living organism rearing function includes a bifacial solar power generation system 10a, a fence section 22, and an egg-laying box 24. The solar power generation system 20 with a living organism rearing function is a system that can generate electricity by receiving sunlight from various directions, and has the function of providing an environment in which hens 26 can lay eggs in a stress-free environment.

[0058] As described above, the bifacial solar power generation system 10a includes the first solar panel unit 12, the second solar panel unit 14, and the support unit 16, but detailed description of each element will be omitted as they have been described above. Here, only elements related to the solar power generation system with organism cultivation function 20 will be described. Here, support members 16a, 16b, and 16c are defined as support units that support the first solar panel unit 12 and the second solar panel unit 14.

[0059] As shown in Fig. 10, the bifacial solar power generation system 10a is a house-type facility in which six support parts 16 are arranged at a predetermined interval, and the first solar panel part 12 and the second solar panel part 14 form the roof. As shown in Fig. 11, each support part 16 is provided with an X-shaped connecting member 28 to increase its strength. This allows the six support parts 16 to be kept stably upright.

[0060] In this way, six support parts 16 are erected and connected with connecting members 28 to form a framework on which four rows and eight columns of first solar panel parts 12 and second solar panel parts 14 are installed, creating a greenhouse-type facility, and a rearing space 31 for free-ranging chickens 26 is formed below the support members 16a, 16b within the facility.

[0061] As shown in Figure 10, a fence section 22 is attached to the periphery of the area of ​​the cultivation space 31 partitioned by the six upright support sections 16. The fence section 22 is preferably made of a mesh member having appropriate strength. The fence section 22 covers the periphery of the six support sections 16, thereby providing a measure against damage by birds and animals and against theft.

[0062] As shown in Figure 10, fence sections 22 are provided around most of the periphery of the area of ​​the rearing space 31 divided by the six upright supports 16, but egg-laying boxes 24 are installed in some areas. The egg-laying boxes 24 divide multiple egg-laying spaces so that multiple hens 26 can enter and exit at the same time, and each egg-laying space has a slope that allows eggs laid in it to slide down to the outside so that they can be removed from the outside.

[0063] Next, we will explain the operation of the above-configured solar power generation system with organism cultivation function 20. As described above, the bifacial solar power generation system 10a among the solar power generation system with organism cultivation function 20 can generate electricity efficiently by being installed in, for example, a grassland, and can therefore earn income by selling the generated electricity.

[0064] In addition, according to the solar power generation system 20 with a function of growing living things, chickens 26 can be raised freely in the growing space 31. For example, 2 This allows for a comfortable rearing density of one chicken per hens, allowing for a stress-free environment for the chickens 26. Furthermore, with the solar power generation system 20 with organism rearing function, the first solar panel unit 12 and the second solar panel unit 14 provide adequate shading and protection from rain, allowing the chickens to live stress-free in the spacious rearing space 31 and also to move to the egg-laying boxes 24 when it is time to lay eggs, allowing for a comfortable environment.

[0065] The EU, which is committed to animal welfare, completely banned the use of conventional cage systems for laying hens as of January 1, 2012. Furthermore, some states in the United States have banned the rearing of laying hens in conventional cages, and producer organizations and related parties have established guidelines, indicating that efforts to promote animal welfare are progressing rapidly worldwide. The photovoltaic power generation system with biological rearing function 20 can realize a chicken-friendly rearing environment that takes into consideration international animal welfare standards. Raising chickens in such a natural environment has the advantage of helping them grow up healthy and vigorous.

[0066] As described above, with the solar power generation system with organism rearing function 20, chickens 26 that are animal welfare-conscious grow up healthy and vigorous, which adds value to the eggs and increases their market value. This has the advantage of enabling income from livestock farming in addition to revenue from power generation.

[0067] Next, a solar power generation system 30 with a creature-growing function that utilizes bihedral solar power generation system 10a will be described. Fig. 12 is a perspective view showing solar power generation system 30 with a creature-growing function. Fig. 13 is a diagram showing solar power generation system 30 with a creature-growing function, with wires 25 stretched across supports 16. Fig. 14 is a diagram showing solar power generation system 30 with a creature-growing function, with grapevines running along wires 25 stretched across supports 16. Here, solar power generation system 30 with a creature-growing function will be described as a system that utilizes bihedral solar power generation system 10a, but similar effects can be achieved with bihedral solar power generation systems 10, 10b, and 10c.

[0068] Solar power generation system 30 with organism cultivation function includes bifacial solar power generation system 10a, fence section 22, and wire section 25. Solar power generation system 20 with organism cultivation function is a system that can generate electricity by receiving sunlight from various directions, and has the function of providing an environment for growing vine-like fruits such as grapes 27 and kiwi.

[0069] The solar power generation system with organism cultivation function 30 has almost the same elements as the solar power generation system with organism cultivation function 20, so a detailed explanation will be omitted, and only the elements related to the solar power generation system with organism cultivation function 30 will be explained.

[0070] The solar power generation system with organism cultivation function 30 does not include an egg-laying box 24, and the fence section 22 covers the entire periphery of the cultivation space 31 area defined by the six support sections 16.

[0071] 13 and 14, the wire section 25 is configured by suspending a plurality of wires extending in the depth direction so as to connect the support members 16c of each support section 16. As shown in Fig. 14, by running the vines of grapes 27 over the plurality of wires, the fruits can be positioned at a predetermined height above the ground.

[0072] Next, we will explain the operation of the above-configured solar power generation system with organism cultivation function 30. As mentioned above, the bifacial solar power generation system 10a among the solar power generation system with organism cultivation function 30 can generate electricity efficiently by being installed in, for example, a grassland, and can earn income by selling the generated electricity.

[0073] In addition, according to the solar power generation system 30 with the organism-growing function, the vines of the grapes 27 can be made to crawl simply by erecting the wire part 25 on the support part 16, so that the role of trellis can be fulfilled without providing costly trellis training.

[0074] Furthermore, according to the solar power generation system with organism cultivation function 30, the first solar panel unit 12 and the second solar panel unit 14 provide adequate shade and rain protection, so there is less need to bag vine fruits such as grapes 27. This has the advantage of reducing the labor required for bagging and labor costs.

[0075] Furthermore, the solar power generation system with organism cultivation function 30 is suitable for preventing damage from birds and animals and theft because the perimeter is covered with the fence section 22. In addition, simply installing the wire section 25 on the support section 16 can serve as a trellis, and because the support section 16 stands upright stably, it is resistant to disasters such as typhoons.

[0076] As described above, the solar power generation system with organism cultivation function 30 does not require trellis preparation and can reduce labor costs for bagging, etc., which can increase the profit margin of farming income. This has the advantage of enabling farmers to earn not only revenue from power generation but also farming income. [Explanation of symbols]
