FIG. DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the following drawings, the same components are denoted by the same reference numerals.

[0009] As shown in FIG. 1 , a solar-cell-equipped carport 10 according to an embodiment of the present disclosure includes a first solar cell array 11 and a second solar cell array 12. The first solar cell array 11 and the second solar cell array 12 may be installed independently of each other. The first solar cell array 11 and the second solar cell array 12 each have the same structure. Features common to both the first solar cell array 11 and the second solar cell array 12 are described below as features of the solar cell array 13.

[0010] 2, the solar cell array 13 includes a power generation unit 14. The solar cell array 13 may further include a plurality of column members 15, a beam member 16, a plurality of rafter members 17, a rain gutter 18, a cap member 19, and a guide member 20.

[0011] The power generation unit 14 includes a plurality of solar cell modules 21. Each solar cell module 21 has a rectangular plate shape. One of the main surfaces of the solar cell module 21 is a light-receiving surface. The main surface is the surface that has the largest area among the planes that define the plate.

[0012] As shown in FIG. 3, the light-receiving surface lrs is defined by a first side s1 and a second side s2 that are perpendicular to each other. The first side s1 may be longer than the second side s2. In the power generating unit 14, the multiple solar cell modules 21 are arranged to be aligned at least along a first direction. The first direction is parallel to the first side s1. In the power generating unit 14, the multiple solar cell modules 21 may also be arranged to be aligned along a second direction. The second direction is parallel to the second side s2. In the power generating unit 14, the multiple solar cell modules 21 may be arranged so that the light-receiving surfaces lrs form the same plane. In the power generating unit 14, the number of solar cell modules 21 aligned along the first direction is preferably four or more.

[0013] A plurality of solar cell modules 21 arranged along the second direction may constitute a string electrically connected in series, and a plurality of solar cell modules 21 arranged along the first direction may each belong to a different string.

[0014] 4, the solar cell module 21 may include a solar cell panel 22 and a frame 23. The solar cell panel 22 may be in the shape of a rectangular plate. The frame 23 may surround the outer edge of the light-receiving surface lrs of the solar cell panel 22.

[0015] As shown in FIG. 5 , the frame 23 may protrude longer on the side opposite the light receiving surface lrs in the normal direction of the light receiving surface lrs than on the light receiving surface lrs side. Specifically, the frame 23 may have side portions 24, a clamping portion 25, and a fixing portion 26. The clamping portion 25 may clamp the vicinity of the outer edge of the main surface of the solar cell panel 22 in the thickness direction of the solar cell panel 22. The clamping portion 25 may have a C-shaped cross section in a direction perpendicular to the normal to the light receiving surface lrs. The side portions 24 may be portions extending from the clamping portion 25 in the direction from the light receiving surface lrs to the back surface. The fixing portion 26 may be frame-shaped when viewed in the normal direction of the light receiving surface lrs. The fixing portion 26 may be a portion having a width inward of the frame at the end of the side portion 24 opposite the light receiving surface lrs.

[0016] 6, the first solar cell array 11 and the second solar cell array 12 are positioned such that a second side s2 located at an end in the first direction of the first solar cell array 11 and a second side s2 located at an end in the first direction of the second solar cell array 12 are substantially parallel to and face each other. Furthermore, the first solar cell array 11 and the second solar cell array 12 are positioned such that a first side s1 of the first solar cell array 11 and a first side s1 of the second solar cell array 12 are substantially parallel to each other when viewed in the vertical direction.

[0017] 1, a distance less than twice the length of the first side s1 of the solar cell module 21 is provided between the first solar cell array 11 and the second solar cell array 12. This distance may further be less than the length of the first side s1. This distance may be more than twice the thickness of the rafter member 17. The thickness of the rafter member 17 may be the length of the solar cell array 13 in a direction perpendicular to the light-receiving surface lrs.

[0018] The power generation unit 14 of the first solar cell array 11 is inclined so that the distance from the horizontal plane decreases as the power generation unit 14 is farther away from the second solar cell array 12. The power generation unit 14 of the second solar cell array 12 is inclined so that the distance from the horizontal plane decreases as the power generation unit 14 is farther away from the first solar cell array 11.

[0019] As shown in FIG. 7, the plurality of column members 15 may be erected on the installation surface is so as to be aligned along the second direction. The installation surface is may be the ground or the like where the solar-cell carport 10 is installed. The installation surface is may be a plane parallel to the horizontal plane, a plane inclined relative to the horizontal plane, or a curved surface. Each column member 15 may be erected by any method. For example, each column member 15 may be erected by pouring it into the ground, embedding it, fixing it to a mounting frame embedded in the installation surface is, or fixing it to a strip foundation or mat foundation. As shown in FIG. 1, the plurality of column members 15 may be erected on the installation surface is so as to be aligned along a direction perpendicular to both the second direction and the vertical direction.

[0020] The column member 15 is, for example, a rod-shaped member having a longitudinal direction. The column member 15 may be a series of steel members, or may be formed by joining multiple steel members by any method such as welding or joints. The column member 15 preferably has a longitudinal direction perpendicular to a horizontal plane, but may also be inclined. The length of each of the multiple column members 15 aligned along a direction perpendicular to both the second direction and the vertical direction may be determined so that the rafter members 17 are inclined with respect to a horizontal plane.

[0021] The girder member 16 may be installed across a plurality of pillar members 15 arranged along the second direction. The girder member 16 may be fixed to the pillar members 15. The girder member 16 may be fixed to the pillar members 15 by any method. For example, the girder member 16 may be fixed by fastening using bolts and nuts, by welding, or by a joint. The girder member 16 may sandwich, for example, a height-adjusting spacer between the girder member 16 and the pillar members 15.

[0022] The girder member 16 may be a columnar member. The girder member 16 may be made of metal. The girder member 16 may be an H-shaped steel beam having an H-shaped cross section perpendicular to the longitudinal direction. The girder member 16 may be a series of steel members, and may be formed by joining multiple steel members by any method such as welding or joints.

[0023] As shown in FIG. 2 , the rafter member 17 may be installed on the girder member 16 so that its longitudinal direction is parallel to the first direction. Specifically, the rafter member 17 may be installed vertically above the girder member 16. The rafter member 17 may be fixed to the girder member 16 by any method. For example, the rafter member 17 may be fixed by fastening with bolts and nuts, by welding, or by a joint. The rafter member 17 may sandwich, for example, a height-adjusting spacer between the rafter member 17 and the girder member 16.

[0024] 8, the multiple rafter members 17 may be spaced apart from one another when viewed vertically from above. Specifically, the multiple rafter members 17 may be spaced apart from one another in the second direction. The interval between the rafter members 17 spaced apart from one another in the second direction may be the length of the second side of the solar cell module 21.

[0025] The rafter member 17 may be a column-shaped member having a longitudinal direction. The rafter member 17 may be made of metal. The rafter member 17 may be an H-shaped steel beam having an H-shaped cross section perpendicular to the longitudinal direction. The rafter member 17 may be a series of steel members, and may be formed by joining multiple steel members by any method such as welding or joints.

[0026] The power generation unit 14 is fixed to the multiple rafter members 17 from vertically above. When viewed vertically from above in the solar cell array 13, the rafter members 17 may be positioned so as to overlap the first sides of each solar cell module 21 constituting the power generation unit 14. The power generation unit 14 may be fixed to the multiple rafter members 17 by fastening them to the fixing portions 26 of the solar cell modules 21 using fastening members such as bolts and nuts. Therefore, as shown in FIG. 7 , different solar cell modules 21 may be fixed to a single rafter member 17 on each side in the second direction. Also, a single solar cell module 21 may be fixed to the rafter members 17 at both ends of the solar cell array 13 in the second direction.

[0027] 9, the rain catcher 18 may have a plate portion 27 and a groove portion 28. The plate portion 27 may be in the shape of a flat plate having a longitudinal direction.

[0028] In the solar cell array 13, the plate portion 27 may be sandwiched between the rafter member 17 and the solar cell module 21. In the solar cell array 13, the plate portion 27 may extend in the same direction as the longitudinal direction of the rafter member 17. In the solar cell array 13, the plate portion 27 may have a width that is longer than the width of the rafter member 17 in the second direction.

[0029] The grooves 28 may be located at both ends in the width direction of the plate portion 27, in other words, in the second direction of the solar cell array 13. The grooves 28 may extend along the longitudinal direction of the plate portion 27. The grooves 28 may be V-shaped when viewed in the longitudinal direction, in other words, in the first direction of the solar cell array 13. The grooves 28 are not limited to being V-shaped when viewed in the longitudinal direction, and may be other shapes such as C-shaped.

[0030] 7, the rain gutter 18 may be provided at least on the rafter members 17 that fix the two solar cell modules 21 in the second direction in the solar cell array 13. Furthermore, the rain gutter 18 may also be provided on the rafter members 17 at both ends in the second direction in the solar cell array 13.

[0031] 2, the cap member 19 may close the gap between two solar cell modules 21 adjacent to each other in the first direction in the solar cell array 13 from the vertically upper side. The cap member 19 may close the gap between two solar cell modules 21 adjacent to each other in the second direction in the solar cell array 13 from the vertically upper side.

[0032] As shown in FIG. 1 , the guide member 20 may be provided near the outer edge of the first solar cell array 11 on the side of the second solar cell array 12. As shown in FIG. 10 , the guide member 20 is specifically a member extending in the second direction and may be provided by being fixed to the rafter members 17 of the first solar cell array 11 using metal fittings or the like so as to connect the multiple rafter members 17 of the first solar cell array 11. Similarly, the guide member 20 may be provided near the outer edge of the second solar cell array 12 on the side of the first solar cell array 11. Furthermore, the guide member 20 is specifically a member extending in the second direction and may be provided by being fixed to the rafter members 17 using metal fittings or the like so as to connect the multiple rafter members 17 of the second solar cell array 12. Note that the guide member 20 may be provided on a member other than the rafter members 17.

[0033] The guide member 20 may be in the form of a plate obtained by bending or curving a flat plate at at least one location. The guide member 20 may be connected to the vertically lower surface of the power generation unit 14 in the solar cell array 13. The guide member 20 may be attached so that the angle of the plate-like main surface relative to the horizontal plane changes and faces vertically upward. By attaching it in this manner, the guide member 20 may be parallel to the second side of the solar cell array 13.

[0034] The carport 10 with solar cells configured as described above includes a first solar cell array 11 and a second solar cell array 12, which are solar cell arrays 13 each having a power generating unit 14 in which a plurality of rectangular, plate-shaped solar cell modules 21, each having a light receiving surface lrs defined by a first side and a second side perpendicular to each other, are arranged so as to be aligned along at least a first direction parallel to the first side, and the first solar cell array 11 and the second solar cell array 12 are arranged such that the second side is located at an end of the first solar cell array 11 in the first direction and the second side is located at an end of the second solar cell array 12 in the first direction. The solar cell arrays 11 and 12 are positioned so that the first and second solar cell arrays 11 and 12 are substantially parallel and facing each other, and the first side of the first solar cell array 11 and the first side of the second solar cell array 12 are substantially parallel when viewed vertically. The first solar cell array 11 and the second solar cell array 12 are spaced apart by a distance less than twice the length of the first side of the solar cell module 21. The power generation unit 14 of the first solar cell array 11 is inclined so that the distance from the horizontal plane decreases with increasing distance from the second solar cell array 12, and the power generation unit 14 of the second solar cell array 12 is inclined so that the distance from the horizontal plane decreases with increasing distance from the first solar cell array 11. In solar cell arrays arranged to form mountains, such as the solar power generation unit described in Patent Document 1, air heated on the vertically lower side of the solar cell array stagnates along the lower surface of the solar cell array near the peaks of the mountains. The stagnation of heated air increases the temperature of the solar cell modules near the mountains, reducing power generation efficiency. Furthermore, the solar cell modules are exposed to high temperatures for long periods of time, which may accelerate degradation of the solar cell modules. To cope with such an event, the carport with solar cells 10 having the above-described configuration uses the chimney effect to discharge the air heated on the backside of the light-receiving surface lrs of the power generating unit 14 of each of the opposing first and second solar cell arrays 11 and 12 from the gap between the first and second solar cell arrays 11 and 12. Therefore, the carport with solar cells 10 can form a strong updraft that discharges hot air vertically upward by causing the air moving due to the chimney effect to meet at the apex.As a result, the solar cell-equipped carport 10 can draw in relatively cool air around the solar cell array 13 to the backside of the power generation unit 14 by discharging heated air. Therefore, the solar cell-equipped carport 10 can cool the solar cell modules 21, thereby reducing a decrease in power generation efficiency. Furthermore, the solar cell-equipped carport 10 having the above-described configuration arranges the power generation units 14 of the opposing first and second solar cell arrays 11 and 12 in a mountain-like configuration, thereby increasing the packing rate of solar cell modules 21 per installation area. Therefore, the solar cell-equipped carport 10 can increase the amount of power generation while effectively utilizing the site area. Furthermore, in the solar cell-equipped carport 10 having the above-described configuration, since the multiple solar cell modules 21 are aligned along the first direction, the air on the backside of the light-receiving surface lrs of the solar cell array 13 is easily heated, increasing the temperature difference with the outside air. Therefore, the solar cell-equipped carport 10 can increase the amount of ventilation on the backside of the solar cell array 13 by increasing the convective air flow rate caused by the temperature difference. As a result, the carport with solar cells 10 further cools the solar cell modules 21, and therefore, the decrease in power generation efficiency can be further reduced.

[0035] Furthermore, in the carport with solar cells 10, the first solar cell array 11 and the second solar cell array 12 are installed independently of each other. With this configuration, the carport with solar cells 10 does not obstruct the updraft passing through the gap between the first solar cell array 11 and the second solar cell array 12. Therefore, the carport with solar cells 10 can cool the solar cell modules 21 to a lower temperature, further reducing the decrease in power generation efficiency.

[0036] In addition, in the solar cell-equipped carport 10, the solar cell array 13 further includes a plurality of pillar members 15 erected on the installation surface is so as to be aligned along a second direction parallel to the second side, a girder member 16 extending across the plurality of pillar members 15, and a plurality of rafter members 17 spaced apart from one another when viewed vertically from above on the girder members 16 so that their longitudinal directions are parallel to the first direction, and the power generation unit 14 is fixed to the plurality of rafter members 17 from vertically above. With this configuration, the solar cell-equipped carport 10 can form an air flow path on the back surface of the power generation unit 14 without being obstructed by the girder members 16. Therefore, the solar cell-equipped carport 10 can improve the flow rate of air exchanged due to the chimney effect.

[0037] Furthermore, in the carport with solar cells 10, the distance between the first solar cell array 11 and the second solar cell array 12 exceeds twice the thickness of the rafter member 17 in a direction perpendicular to the light-receiving surface lrs. In the carport with solar cells 10, an air flow layer, which is a layer the thickness of the rafter member 17, can be formed in one of the solar cell arrays 13. Therefore, in the carport with solar cells 10 having the above-described configuration, the area of ​​the gap between the first solar cell array 11 and the second solar cell array 12 exceeds the sum of the cross-sectional areas of the flow paths defined between the adjacent rafter members 17 in the first solar cell array 11 and the second solar cell array 12. Therefore, the carport with solar cells 10 can reduce the decrease in the flow rate of the rising air current passing through the gap between the first solar cell array 11 and the second solar cell array 12. Therefore, the carport with solar cells 10 can cool the solar cell modules 21 to a lower temperature, further reducing the decrease in power generation efficiency.

[0038] In the solar-cell carport 10, the solar cell array 13 further includes rain gutter 18, which is sandwiched between the rafter members 17 and the solar cell modules 21 and includes a flat plate portion 27 extending in the same direction as the longitudinal direction of the rafter members 17, and includes V-shaped grooves 28 located at both ends of the plate portion 27 in the second direction and viewed from the longitudinal direction. With this configuration, as shown in Fig. 11, between adjacent rain gutter 18 in the second direction, heated air is concentrated near the rear surfaces of the solar cell modules 21 along the slopes of the V-shaped grooves 28, thereby increasing the flow rate and speed of the ascending air current along the rear surface due to the chimney effect.

[0039] In the carport with solar cells 10, the solar cell array 13 further includes a cap member 19 that closes the gap between two adjacent solar cell modules 21 in the first direction from above. This configuration allows the carport with solar cells 10 to reduce upward leakage of air heated behind the light-receiving surface (lrs) of each solar cell module 21 through the gaps between the solar cell modules 21 aligned along the first direction. Therefore, the carport with solar cells 10 can increase the flow rate and speed of the updraft between the first solar cell array 11 and the second solar cell array 12. As a result, the carport with solar cells 10 increases the amount of air entrained in the updraft on the light-receiving surface (lrs) side of the power generation unit 14 of the solar cell array 13, thereby increasing the convection formed on the light-receiving surface (lrs) side. Due to this convection, the carport with solar cells 10 can cool the solar cell array 13 from the light-receiving surface (lrs) side as well.

[0040] In the solar-powered carport 10, the solar cell module 21 includes a rectangular solar cell panel 22 and a frame 23 surrounding the outer edge of the solar cell panel's light-receiving surface (LRS). The frame 23 extends from the opposite side of the light-receiving surface (LRS) in the normal direction of the light-receiving surface (LRS) so that it is longer than the light-receiving surface (LRS) side, and its first side is longer than its second side. The frame 23 can act as a resistance to airflow along the back side of the power generation unit 14 behind the light-receiving surface (LRS). To address this issue, the solar-powered carport 10 with the above-described configuration can reduce the number of frames 23 aligned in the first direction compared to a configuration in which a power generation unit with the same overall size in the first and second directions is formed using solar cell modules whose second side is longer than the first side. Therefore, the solar-powered carport 10 has fewer frames 23 that act as resistance to airflow, thereby reducing the reduction in airflow volume and flow velocity.

[0041] Furthermore, in the carport with solar cells 10, the first solar cell array 11 further has a guide member 20 that extends parallel to the second side near the outer edge on the second solar cell array 12 side and faces vertically upward while changing its angle with respect to the horizontal plane from the vertically below the power generation unit 14 of the first solar cell array 11. With this configuration, the carport with solar cells 10 can increase the flow speed of the updraft that occurs in the gap between the first solar cell array 11 and the second solar cell array 12.

[0042] Furthermore, in the solar cell-equipped carport 10, the solar cell array 13 includes multiple solar cell modules 21 arranged along a second direction parallel to the second side. The solar cell modules 21 arranged along the second direction form strings electrically connected in series, while the solar cell modules 21 arranged along the first direction belong to separate strings. Among the multiple solar cell modules 21 arranged along the first direction, the solar cell modules 21 positioned higher in the vertical direction tend to be warmer than the solar cell modules 21 positioned lower in the vertical direction. Therefore, the power generation efficiency of the solar cell modules 21 positioned lower in the vertical direction tends to be higher than that of the solar cell modules 21 positioned higher in the vertical direction. For multiple solar cell modules 21 constituting a single string, uniform output is preferable to increase the amount of power generated by the string. In response to this issue, the solar cell-equipped carport 10 having the above-described configuration forms a string with multiple solar cell modules 21 whose temperatures are expected to be relatively close to each other, thereby enabling the power generation efficiency of the multiple solar cell modules 21 constituting any given string to approach uniformity. Therefore, the solar cell-equipped carport 10 can increase the overall output of the solar cell array 13.
