DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] (Solar carport) A solar carport in one embodiment of the present invention comprises a support pillar driven into the ground, a roof portion on which the support pillar is arranged and extended from the support pillar, a number of solar panels arranged on the roof portion, a joint portion that joins a first mounting bracket attached to the support pillar side end of the roof portion and a second mounting bracket attached to the roof portion side end of the support pillar in a position adjustable manner, and a fixing portion that fixes the support pillar to the ground by driving a number of reinforcing piles into the support pillar from a number of different directions, and preferably has a rainwater collector provided along the gaps between adjacent solar panels, and further has other components as necessary.

[0010] The solar carport of one embodiment of the present invention can effectively utilize the upper space (dead space) in parking lots of factories, hospitals, city halls, universities, convenience stores, shopping malls, supermarkets, pachinko parlors, etc. for solar power generation, and can also protect cars and parking lot users from rain, wind, direct sunlight in midsummer, etc.

[0011] <Strut> The pillars are directly driven into the ground of the parking lot. In other words, the pillars themselves are driven directly into the ground without using piles or digging holes. This eliminates the need for concrete, significantly shortens the time it takes to install the pillars, and reduces costs. The method for driving the posts is not particularly limited and can be appropriately selected depending on the purpose. For example, the driving can be performed using a pile driver.

[0012] There are no particular limitations on the material, shape, size, number, structure, etc. of the support columns, and they can be appropriately selected depending on the purpose. The material of the support is not particularly limited and can be appropriately selected depending on the purpose, and examples thereof include metal, wood, ceramics, etc. Among these, metal is preferable from the viewpoint of durability and strength. Examples of the metal include iron, steel, aluminum, aluminum alloy, stainless steel, etc. The shape of the support is not particularly limited and may be appropriately selected depending on the purpose, and examples thereof include a solid or hollow rectangular column, a cylindrical column, a rectangular tube, a rectangular column, etc. In addition, it is preferable that the support has a plurality of ribs in order to improve its strength. There are no particular limitations on the size, number and structure of the supports, and they can be appropriately selected depending on factors such as the size of the roof of the solar carport. In addition, it is preferable that the portion of the support that comes into contact with the ground be treated to prevent corrosion.

[0013] <Roof section> The roof portion is disposed above the parking space, covers the entire surface of the parking space, and is supported by pillars, and a plurality of solar panels are arranged on the roof portion. There are no particular limitations on the shape, size, material, structure, etc. of the roof portion, and they can be appropriately selected depending on the purpose. The roof is shaped like a Y with a support pillar driven into the ground and extending from the support pillar, with the support pillar in the center. This Y-shape improves strength and increases the storage space for cars, allowing more cars to be stored.

[0014] Examples of the material for the roof portion include metal materials such as iron, aluminum, stainless steel, and titanium, and hard resins other than metal materials. Examples of the hard resin material include polyvinyl chloride resin (PVC), polystyrene resin (PS), acrylonitrile-butadiene-styrene copolymer (ABS) resin, and polymethylmethacrylate resin (PMMA) resin.

[0015] The structure of the roof is not particularly limited as long as multiple solar panels can be arranged on the roof, and various structural members can be appropriately selected. For example, the roof may be flat, or may have a stand consisting of multiple vertical bars and multiple horizontal bars perpendicular to the vertical bars. Among these, a stand is preferred because it can reduce weight. Furthermore, when multiple solar panels are arranged on the stand, the stand and the multiple solar panels together form a roof, and function to receive rain, wind, etc. Furthermore, since the stand is located at the end of the solar panel, light can easily enter from the back side, making double-sided power generation possible.

[0016] When the roof portion has a frame, it is preferable that two supports are connected to one of the vertical beams, and a brace structure is formed between the two supports. It is preferable that two supports are connected to each of the multiple vertical beams, and a brace structure is formed between the two supports. The brace structure, also known as a "diagonal brace," is installed on the diagonal of a square formed between two adjacent pillars to prevent deformation of the solar carport. The brace structure plays a role in connecting and transmitting the load of the roof sections on both sides, and as a result of canceling out the moment of the load of the roof sections on both sides, stress can be reduced, and the number of supports can be reduced.

[0017] Furthermore, when the roof portion has a mounting base, it is preferable that one support pillar is connected to one of the vertical beams. By connecting one support pillar to one vertical beam of the mounting base, it is possible to shorten the construction period and reduce costs. When connecting one support pillar to one vertical beam of the mounting base, it is preferable that the fixing portion of the support pillar is fixed to the ground by driving four reinforcing piles into the support pillar from four different directions at approximately the center of the support pillar.

[0018] <Solar panels> The solar panel is disposed on the roof portion and generates solar power. The solar panel includes a plurality of solar cell elements, a first protective member disposed on the light-receiving surface side of the solar cell elements, and a second protective member disposed on the back surface side of the solar cell elements. The solar cell elements are sandwiched between a first protective member and a second protective member and sealed with a filler. The solar cell panel also includes wiring members and the like that are attached to the electrodes of the solar cell elements and connect adjacent solar cell elements to each other.

[0019] A solar panel is equipped with multiple solar cell elements called cells inside. In addition, a terminal box that houses the connection between the lead wires drawn from the edge of the panel and the power lines that output current from the solar panel is attached to the back side of the solar panel with adhesive or other means. The solar cell element includes a photoelectric conversion unit that generates carriers by receiving sunlight. The photoelectric conversion unit has, for example, a light-receiving surface electrode formed on a light-receiving surface and a back surface electrode formed on a back surface.

[0020] The photoelectric conversion unit has a semiconductor substrate such as crystalline silicon (c-Si), gallium arsenide (GaAs), indium phosphide (InP), etc., an amorphous semiconductor layer formed on the substrate, and a transparent conductive layer formed on the amorphous semiconductor layer. Specifically, the structure may include an i-type amorphous silicon layer, a p-type amorphous silicon layer, and a transparent conductive layer formed in this order on the light receiving surface of an n-type single crystal silicon substrate. The transparent conductive layer is preferably made of a transparent conductive oxide such as indium oxide (In2O3), zinc oxide (ZnO), or other metal oxide doped with tin (Sn), antimony (Sb), or the like.

[0021] The electrode is composed of, for example, a plurality of finger portions and a plurality of bus bar portions. The finger portions are thin-line electrodes formed over a wide area on the transparent conductive layer, and the bus bar portions are electrodes that collect carriers from the finger portions. The wiring material is attached to the bus bar portions.

[0022] The first protective member may be, for example, a light-transmitting member such as a glass substrate, a resin substrate, a resin film, etc. Among these, a glass substrate is preferable from the viewpoints of fire resistance, durability, etc. The second protective member may be made of the same material as the first protective member, or may be made of a non-transparent material if light incidence from the back surface side is not anticipated. The first and second protective members may each be a light-transmitting glass substrate.The filler may be, for example, a resin such as ethylene vinyl acetate copolymer (EVA).

[0023] A frame is provided around the edge of the solar panel, and is made of a metal such as iron, stainless steel, or aluminum, with aluminum being preferred from the standpoint of weight reduction. The frame protects the edges of the solar panels and is used to fasten adjacent solar panels together, etc. The frame is configured by combining a plurality of frames and surrounds the solar panels on all four sides.

[0024] <Joint part> The joint joins a first mounting bracket attached to the end of the roof section facing the support pillar and a second mounting bracket attached to the end of the support pillar facing the roof section in an adjustable manner. This makes it easy to connect the roof section and the support pillar even if the support pillar becomes misaligned, reducing the effort and labor required for positioning work.

[0025] There are no particular limitations on the method of attaching the first mounting bracket to the end of the roof section facing the support pillar, and the method can be selected appropriately depending on the purpose. Examples include a method of fixing the first mounting piece of the first mounting bracket to the end of the vertical bar of the roof section using a bolt and nut through the first fixing hole of the first mounting piece, and a method of welding the first mounting piece of the first mounting bracket to the end of the vertical bar of the roof section. There are no particular limitations on the method of attaching the second mounting bracket to the roof side end of the pillar and it can be selected appropriately depending on the purpose. Examples include a method of fixing the second mounting bracket to the roof side end of the pillar using a bolt and nut through the second fixing hole of the second mounting piece of the second mounting bracket, and a method of welding the second mounting piece of the second mounting bracket to the roof side end of the pillar.

[0026] The first mounting bracket has a first long hole formed to be long in the width direction, and the second mounting bracket has a second long hole formed to be long in the rotational direction, and the first mounting bracket and the second mounting bracket are joined with the positions of the first long hole and the second long hole adjusted, and the support and the roof portion are connected by fastening the first long hole and the second long hole with a fastener. The fasteners include, for example, bolts and nuts, screws, rivets, and the like. In the present invention, "joining," "connecting," or "attaching" refers to inserting a bolt into one or more long holes provided in each of a plurality of members and fastening the bolt with a nut, but various other methods can be used as long as they similarly facilitate assembly and disassembly. Alternatively, welding or other methods can be used as needed to increase strength.

[0027] The multiple first long holes of the first mounting bracket are long holes formed long in the fore-and-aft direction (width direction), and allow the position of the joint between the first mounting bracket and the second mounting bracket to be adjusted in the fore-and-aft direction (width direction). The multiple second long holes of the second mounting bracket are long holes formed to be long in the left-right direction (rotational direction), and allow the position of the joint between the first mounting bracket and the second mounting bracket to be adjusted in the left-right direction (rotational direction). The first slots and the second slots are provided in plurality.

[0028] There are no particular limitations on the material, shape, size, structure, etc. of the first mounting metal fitting and the second mounting metal fitting, and they can be appropriately selected depending on the purpose. The material of the first and second mounting fittings is not particularly limited and can be appropriately selected depending on the purpose, and examples thereof include metal, wood, ceramics, etc. Among these, metal is preferable. Examples of the metal include iron, steel, aluminum, aluminum alloy, stainless steel, etc. The shape of the first and second mounting fittings is not particularly limited and may be appropriately selected depending on the purpose. Examples of the shape include a disk shape and a rectangular disk shape. There are no particular limitations on the size and structure of the first and second mounting fittings, and they can be selected appropriately depending on the purpose.

[0029] <Fixed part> The fixing portion fixes the support to the ground by driving a plurality of reinforcing piles from a plurality of different directions. By having the fixing portion, the pull-out strength of the support is improved when the support is directly driven into the ground. As a result, the number of support columns can be reduced. The fixing portion is preferably formed by driving four reinforcing piles into the support from four different directions at the approximately center of the support to fix the support to the ground, in order to further improve the pull-out strength. It is more preferable that the four reinforcing piles are evenly arranged radially around the support. Specifically, a first fixing bracket and a second fixing bracket are attached to the support, and a reinforcing pile is inserted into the guide tube provided on the first and second fixing brackets and driven in to fix the support to the ground. The first and second fixing metal fittings are preferably attached to a portion of the support pole other than the ends, and more preferably attached to approximately the center of the support pole.

[0030] There are no particular limitations on the material, shape, size, structure, etc. of the first fixing metal fitting and the second fixing metal fitting, and they can be appropriately selected depending on the purpose. The material of the first and second fixing metal fittings is not particularly limited and can be appropriately selected depending on the purpose, and examples thereof include metal, wood, ceramics, etc. Among these, metal is preferable from the viewpoint of strength. Examples of the metal include iron, steel, aluminum, aluminum alloy, stainless steel, etc. The size and shape of the first and second fixing metal fittings can be appropriately selected according to the shape and size of the support pole. The structure of the first and second fixing metal fittings is not particularly limited and can be appropriately selected depending on the purpose.

[0031] The method of attaching the first and second fixing brackets to the support is not particularly limited and can be selected appropriately depending on the purpose. Examples include a method of fixing them with bolts and nuts through mounting holes in the first and second fixing brackets and mounting holes in the support, and a method of welding the first and second fixing brackets to the support.

[0032] The first and second fixing brackets are each provided with a guide pipe. The guide pipe serves to guide the reinforcing pile so that it can be driven into the ground at a predetermined angle when the reinforcing pile is driven into the ground. The guide pipes are inclined at different angles from each other. The guide pipes are attached to the first and second fixing brackets by welding or via attachment pieces. The number of guide pipes provided on the first or second fixing metal fitting is preferably 1 or more, more preferably 2 or more. The guide pipes are preferably arranged in different directions relative to the support pillar, and more preferably in a direction in which a plurality of reinforcing piles cross each other when the reinforcing piles are inserted into the guide pipes. The material, shape, size, structure, etc. of the reinforcing pile are not particularly limited and can be appropriately selected according to the purpose. The material of the reinforcing pile can be metal, resin, or other material. The reinforcing pile is a long rod having a predetermined length and having a cylindrical, square pillar, cylindrical, square tube, etc.

[0033] <Rainwater collection> The rainwater collector is provided in the gap between the adjacent solar panels. The rainwater collector can collect raindrops leaking through the gap between the adjacent solar panels and guide them to below the roof, thereby preventing water leakage from the solar carport. The rainwater collector may be provided along the gap between adjacent solar panels, or may be provided across the gap. If the rainwater collector is provided across the gap, it can also be used in cases where the solar panels expand thermally due to changes in temperature, etc., causing the gap to change. The rainwater collected in the rainwater collector flows through the rainwater collector and is drained through a drainage hole provided at the end of the rainwater collector and down a gutter.

[0034] <Other materials> Examples of the other members include a decorative cover and a reinforcing member. The decorative cover is attached to the outer periphery of the solar panel arranged on the roof, and can enhance the design by hiding the frame, rainwater collector, etc. from view. The reinforcing member is connected to the support pillar and supports the roof portion.

[0035] (Manufacturing method of solar carport) A manufacturing method for a solar carport according to one embodiment of the present invention is a manufacturing method for a solar carport according to one embodiment of the present invention, and includes a driving step of driving a support pillar directly into the ground, a joining step of joining a first mounting bracket attached to the support side end of the roof part and a second mounting bracket attached to the roof side end of the support pillar so that the position can be adjusted, and a fixing step of driving a plurality of reinforcing piles into the support pillar from a plurality of different directions to fix the support pillar to the ground, and further includes other steps as necessary.

[0036] In the method for manufacturing a solar carport according to one embodiment of the present invention, the posts are directly cast into the ground, so concrete is not used and the time required for installing the posts can be significantly reduced, which is extremely advantageous in terms of cost. In addition, if the position of the post is misaligned during casting, the position can be adjusted using a first mounting bracket attached to the end of the roof part on the post side and a second mounting bracket attached to the end of the post on the roof side, so that the solar carport can be manufactured very efficiently. Furthermore, by providing a fixing part in the fixing process, the pull-out strength of the post is improved when the post is directly driven into the ground, so the number of posts can be reduced.

[0037] Here, an embodiment of the solar carport of the present invention will be described in detail with reference to the drawings. In each drawing, the same components are given the same reference numerals, and duplicated explanations may be omitted. In addition, the number, position, shape, etc. of the following components are not limited to the present embodiment, and may be the number, position, shape, etc. that are preferable for implementing the present invention.

[0038] <First embodiment> FIG. 1 is a schematic side view showing an example of a solar carport of the present invention, and FIG. 2 is a schematic plan view showing an example of a solar carport of the present invention. The solar carport 10 shown in Figures 1 and 2 has a pair of pillars 11, 11 driven into the ground 18 arranged in the center, a roof portion 12 extending in both left and right directions from the pillars, and a number of solar panels 13 arranged on the roof portion.

[0039] The posts 11 are made of stainless steel and are driven into the ground 18 of the parking lot. In other words, the posts themselves are driven directly into the ground as piles without using piles or digging holes. This eliminates the need for concrete, significantly shortens the time required to install the posts, and is cost-effective.

[0040] As shown in Fig. 1, the roof portion 12 has a base made up of a plurality of vertical beams 14 and a plurality of horizontal beams 15. A plurality of solar panels 13 are arranged on the base. The stand has four equally spaced vertical beams 14 on each side, and four equally spaced horizontal beams 15 on each side (a total of eight), with the vertical beams 14 and horizontal beams 15 being perpendicular to each other. As shown in FIG. 1, two support pillars 11, 11 are connected to one vertical beam 14, and although not shown, two support pillars 11, 11 are also connected to each of the three vertical beams 14 located at the back. The multiple vertical beams 14 are inclined so that the support pillar 11 side is located downward, and the solar panel 13 arranged on the stand is also inclined in the same manner.

[0041] In Fig. 1, 16 is a brace structure, which is installed on the diagonal of a rectangle formed between two supports 11, 11 connected to one vertical beam 14 in order to prevent deformation of the solar carport due to the application of load. The brace structure 16 plays a role in connecting and transmitting the load of the roof portions on both the left and right sides, and as a result of canceling out the moment of the load of the roof portions on both the left and right sides, stress can be reduced, and the number of supports can be reduced. Reference numeral 17 denotes a reinforcing member which is connected to the support pillars 11 and supports the roof portion 12.

[0042] As shown in Figure 3, the solar carport 10 can accommodate two automobiles 100 side by side under the roof portion 13 extending on both the left and right sides, and can also accommodate four automobiles at the back, for a total of six automobiles.

[0043] Solar carports need to be strong enough to not collapse even when subjected to various external loads, such as when the solar panel surface is exposed to strong winds, when the load on the solar panel surface increases due to snow accumulation, or when an earthquake occurs.

[0044] FIG. 4 is a diagram for explaining the basic principle of how snow causes a load to be applied to a solar carport. Moment due to snow load: M = S L (Nm) Formula (1) In the above formula (1), L is the distance (m) from the support pillar part that serves as the fulcrum to the point of application, and S is the snow load (N). Stress degree: σ=M / Z(N / mm 2 )···Formula (2) In the above formula (2), Z is the section modulus of the examined member (mm 3 ), and M represents the moment due to snow load. Therefore, by making the solar carport of one embodiment of the present invention symmetrical at the front and back, and by applying a moment in the opposite direction to the moment M due to the snow load, the stresses can be offset and reduced, thereby allowing the number of pillars to be reduced.

[0045] <Modification 1 of the First Embodiment> FIG. 5 is a schematic side view showing another example of the solar carport of the present invention, and FIG. 6 is a schematic front view showing another example of the solar carport of the present invention. A solar carport 50 shown in Figures 5 and 6 has one support pillar 51 driven into the ground 18, a roof portion 52 extending in both left and right directions from the support pillar 51 arranged in the center, and multiple solar panels 54 arranged on the roof portion. In Figure 5, 55 is a brace, 18 is the ground, and 100 is an automobile. This solar carport 50 has a single support pillar 51 connected to one vertical beam 53 of the frame of the roof portion 52, thereby reducing the number of supports in the entire solar carport, thereby shortening construction time and reducing costs.

[0046] <Modification 2 of the First Embodiment> Fig. 7 is a schematic side view showing another example of the solar carport of the present invention. The solar carport 60 in Fig. 7 has one support 61 driven into the ground 18, a roof 62 extending in one direction from the support 61, and multiple solar panels 64 arranged on the roof. In Fig. 7, 65 is a brace, 18 is the ground, and 100 is an automobile. This solar carport 60 has a roof portion 62 on only one side, which allows space saving and allows for effective use of a small lot.

[0047] <Second embodiment> Figure 8 shows a joint that joins a first mounting bracket attached to the end of the roof part of a solar carport on the pillar side and a second mounting bracket attached to the end of the pillar on the roof side in a position adjustable manner. At the joint 19, the support pillar 11 and the vertical beam 14 of the roof portion are connected. The first mounting bracket 20 and the second mounting bracket 24 are both disk-shaped and made of iron, and by joining them together, it is possible to adjust positional deviations of the support pillar 11 in the rotational direction and the front-rear direction.

This first mounting bracket 20 has a first elongated hole 21, a first mounting piece 22, and a first fixing hole 23. The first mounting bracket 20 is fixed to the end of the vertical beam 14 of the roof portion through the first fixing hole 23 of the first mounting piece 22 with a bolt and nut. The first oblong hole 21 of the first mounting member 20 is an oblong hole formed long in the front-rear direction (width direction), and its position in the direction of the arrow a in FIG. 9A (width direction) is adjustable.

A first fixing metal fitting 41 and a second fixing metal fitting 42 are attached to the support pillar 11 at approximately the center thereof with bolts and nuts. The first fixing metal fitting 41 and the second fixing metal fitting 42 are both made of iron and have a generally U-shape, and are firmly attached to the support pillar 11. The first fixing bracket 41 and the second fixing bracket 42 are each provided with two guide pipes 43, totaling four. The four guide pipes 43 serve to guide the reinforcing piles 44 so that they can be driven into the ground at a predetermined angle when the piles are driven into the ground. The four reinforcing piles 44 are evenly arranged radially around the support 11.

[0052] FIG. 14 is a perspective view showing an example of a first fixing bracket, FIG. 15 is a perspective view showing an example of a second fixing bracket, FIG. 16 is a side view showing an example of the first fixing bracket, and FIG. 17 is a side view showing an example of the second fixing bracket. The first fixing bracket 41 and the second fixing bracket 42 are substantially U-shaped, each having two guide tubes 43, and are attached to the support 11 with bolts and nuts at four first mounting holes 45. The first fixing bracket 41 and the second fixing bracket 42 are joined to each other with bolts and nuts via the support 11 at four second mounting holes 46.

[0053] The left diagram of Fig. 18 is a top view showing an example of a reinforcing pile, and the right diagram of Fig. 18 is a side view showing an example of a reinforcing pile. The reinforcing pile 44 is made of metal and has a cylindrical shape and is a long rod having a predetermined length. 19 is a schematic diagram showing a state in which the support pillar is fixed to the ground with multiple reinforcing piles. The reinforcing piles 44 are inserted through guide pipes 43 provided on the first fixing bracket 41 and the second fixing bracket 42 and driven into the ground to form fixing parts 47, which can prevent the support pillar 11 from being pulled out.

[0054] <Fourth embodiment> Fig. 20 is a diagram showing an example of a rainwater collector in a solar carport. A rainwater collector 30 is provided between multiple solar panels 13 arranged on the roof and adjacent solar panels. This rainwater collector 30 can collect raindrops leaking from gaps 31 between adjacent solar panels 13 and guide them below the sloped roof, preventing water leakage. The rainwater collector 30 may be provided along the gap 31 between adjacent solar panels as shown in FIG. 20, or may be provided across the gap 31 between adjacent solar panels 13 as shown in FIG. As shown in FIG. 21, by providing a rainwater collector 30 spanning the gap 31 between adjacent solar panels 13, it is possible to accommodate cases where the solar panels thermally expand due to exposure to sunlight and the size of the gap changes.
