Description

[Technical Field]

[0001] The present invention relates to a mounting structure for a solar cell module, and more particularly to a mounting structure for a solar cell module containing a perovskite compound. [Background technology]

[0002] In recent years, the use of power generation systems using solar panels has become widespread with the aim of reducing greenhouse gases such as carbon dioxide. Solar panels are usually installed on the rooftops of buildings to increase power generation efficiency. Various methods are used to install solar panels on rooftops or roofs, such as using screws or adhesives.

[0003] For example, Patent Document 1 discloses a solar cell-mounted metal coping that uses a metal coping installed on the upper end surface of a parapet wall erected along the edge of a building roof. Flexible solar cells are attached to the top end of the metal coping installed at the top of the parapet wall erected along the edge of the building roof. The flexible solar cells are adhered to the top end of the metal coping with an adhesive. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-342573 Summary of the Invention [Problem to be solved by the invention]

[0005] Recently, solar cell panels containing perovskite compounds have been developed. However, perovskite compounds generally have short lifespans and poor durability. Therefore, if they are completely fixed to a roof or rooftop with adhesives or the like, they are difficult to replace.

[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a solar cell module mounting structure that allows for easy replacement of solar cell modules. [Means for solving the problem]

[0007] In response to the above-mentioned problems, the present invention provides a mounting structure for a solar cell module containing a perovskite compound, which is mounted to a wall of a balcony and comprises a protruding portion that protrudes from the wall toward the outside, and a gripping portion that protrudes in a direction intersecting the protruding direction of the protruding portion and grips the solar cell module along the extension direction of the wall, and is characterized in that the gripping portion has a pair of claw portions that detachably clamp and hold the solar cell module from both sides in the thickness direction.

[0008] Here, it is desirable that the wiring extending from the solar cell module and a wiring box accommodating the wiring are housed within the coping.

[0009] The solar cell module is preferably rectangular in shape when viewed from the front, and the gripping portion is adapted to grip either a long side or a short side of the solar cell module. The solar cell module preferably has a solar cell panel, and the surface of the solar cell panel facing the outdoor side is preferably covered with a transparent protective member. [Effects of the Invention]

[0010] The solar cell module mounting structure of the present invention comprises a protruding portion that protrudes from the balcony wall toward the outside, and a gripping portion that grips the solar cell module along the direction in which the wall extends, and the gripping portion has a pair of claws that detachably clamp and hold the solar cell module from both sides in the thickness direction.

[0011] This allows the solar cell module to be installed in a clamped state on the outside of the balcony, which is a part other than the roof. Therefore, when attaching the solar cell module to the gripping part, it is only necessary to slide the solar cell module from above between the pair of claws, making it easy to replace the solar cell module that needs to be replaced due to deterioration over time.

[0012] In addition, the wiring extending from the solar cell module and the wiring box that houses the wiring are housed within the capping board, which prevents the wiring and wiring box of the solar cell module from being exposed to ultraviolet rays, thereby preventing deterioration of the wiring and wiring box of the solar cell module due to ultraviolet rays.

[0013] Furthermore, the solar cell module is formed in a rectangular shape when viewed from the front, and the gripping portion grips either the long side or the short side of the solar cell module. This allows the solar cell module to be attached in a state where it can easily receive sunlight, thereby improving power generation efficiency.

[0014] The solar cell module also has a solar cell panel, the outdoor surface of which is covered with a transparent protective member. This means that the solar cell panel is covered with a weather-resistant and transparent protective member, which prevents damage from flying objects and prevents deterioration of the solar cell panel due to ultraviolet rays.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, an inner wall installation method according to an embodiment of the present invention will be described with reference to the drawings.

[0017] Fig. 1 is a perspective view of a balcony 100 to which a mounting structure according to an embodiment of the present invention is applied. As shown in Fig. 1, the balcony 100 is configured to have a balustrade wall (wall portion) 110 rising from a floor portion (not shown), a headboard 120 covering the upper end of the balustrade wall 110, a plurality of support posts 130 provided above the headboard 120, and balustrade bars 140 provided at the upper ends of the support posts 130.

[0018] The headboard 120 is provided along the extension direction of the balustrade wall 110, and multiple support posts 130 are arranged at intervals on the headboard 120. Multiple solar cell modules 1 are attached to the outdoor side of the balustrade wall 110. Each solar cell module 1 is a thin plate-like member formed into a rectangular shape when viewed from the front and elongated in the vertical direction.

[0019] 2 is a schematic diagram of the solar cell module 1. The solar cell module 1 is formed in a rectangular shape when viewed from the front, and is configured to have a solar cell panel 11 and a frame 12. The solar cell module 1 has a structure in which the solar cell panel 11, which functions as a light receiving surface, is attached to the frame 12. Both the solar cell panel 11 and the frame 12 are formed in a flat plate shape.

[0020] A protective member 13 that covers the surface of the solar cell panel 11 may be attached to the side of the solar cell panel 11 opposite the frame 12. The protective member 13 is, for example, a transparent, flat member made of glass, acrylic, or the like. When the solar cell module 1 having the protective member 13 is attached to the balustrade wall 110, the frame 12, solar cell panel 11, and protective member 13 are arranged in this order from the inside to the outside of the room. A transparent protective layer may be applied to the surface of the solar cell panel 11 as the protective member 13, and a transparent resin hardener that has weather resistance, waterproofing, and physical strength may be applied as a protective material (top coat).

[0021] Fig. 3 is a diagram for explaining the installation state of the solar cell module 1, and Fig. 4 is an enlarged view of part A in Fig. 3. As shown in Fig. 3, the balustrade wall 110 is configured to have an inner wall 111 located on the indoor side, an outer wall 112 located on the outdoor side, and a stud 113 sandwiched between the inner wall 111 and the outer wall 112.

[0022] Here, the solar cell panel 11 has a perovskite solar cell in which an organic-inorganic perovskite compound having a perovskite structure using lead, tin, etc. is used in the photoelectric conversion layer. The perovskite compound is a structure having a perovskite crystal structure or a crystal similar thereto, and is light and highly flexible.

[0023] Perovskite solar cells are less durable than conventional solar cells. Therefore, the solar cell panel 11 needs to be replaced at intervals shorter than the time it takes to rebuild a house. Therefore, the solar cell module 1 having the solar cell panel 11 is not permanently fixed to the exterior wall 112, but is instead attached in a replaceable manner.

[0024] The solar cell module 1 is attached to a mounting member 50 that protrudes from the balustrade wall 110 toward the outside. The mounting member 50 is joined to the exterior wall 112 and studs 113 with joining members 60 such as screws. While Fig. 3 shows an example in which the solar cell module 1 is attached to both sides of the mounting member 50, it may also be attached to only one side of the mounting member 50. The mounting member 50 is attached to the balustrade wall 110 with the solar cell module 1 sandwiched between them from both sides in the thickness direction.

[0025] As shown in Fig. 4, mounting member 50 is configured to have a protruding portion 51 and a pair of gripping portions 52 provided on both sides of protruding portion 51. Protruding portion 51 is provided so as to protrude from exterior wall 112 toward the outside of the room, and is joined to stud 113 via exterior wall 112 by joining member 60.

[0026] The gripping portion 52 has a pair of claws 52a extending along the outer wall 112. The gripping portion 52 is made of an elastically deformable material such as rubber, and the pair of claws 52a, which are elastically deformed when the solar cell module 1 is inserted, elastically return to their original shape to grip the solar cell module 1. The pair of claws 52a grip the long side portions of the solar cell module 1.

[0027] 5 is a side view of the attached solar cell module 1. As shown in FIG. 5, the wiring box 20 is housed in the head board 120 together with wiring (not shown). That is, the wiring box 20 is placed in the space formed by the inner wall 111, the outer wall 112, and the head board 120.

[0028] A support member 70 that supports the solar cell module 1 from below is provided on the outer wall 112. The support member 70 is connected to the outer wall 112 with a connecting member 71 such as a screw. The support member 70 may be provided in an appropriate position taking into consideration the vertical dimensions of the mounting member 50 and the solar cell module 1. The support member 70 supports the lower end 1a of the solar cell module 1 from below, preventing the solar cell module 1 from falling.

[0029] By gripping the solar cell module 1 with the pair of gripping parts 52, the solar cell module 1 is maintained in a removable state without being completely fixed to the outer wall 112 with adhesive. In addition, to prevent the solar cell module 1 from falling, the solar cell module 1 is supported from below by the support member 70.

[0030] 6 is a schematic diagram showing the arrangement of solar cells 10 in a solar cell module 1. The solar cell module 1 has a plurality of solar cells 10, and the solar cells 10 are connected in parallel in a monolithic structure by wiring 21. Note that the solar cells 10 may not be connected in parallel, but may also be connected in series.

[0031] In this way, the mounting structure for the solar cell module 1 of the present invention comprises a protruding portion 51 that protrudes from the balcony railing wall (wall portion) 110 toward the outside of the room, and a gripping portion 52 that grips the solar cell module 1 along the extension direction of the railing wall 110, and the gripping portion 52 has a pair of claw portions 52a that detachably clamp and hold the solar cell module 1 from both sides in the thickness direction.

[0032] Therefore, the solar cell module 1 can be installed in a clamped state on the outside of the balcony, which is a part other than the roof. Therefore, when attaching the solar cell module 1 to the gripping part 52, it is only necessary to slide the solar cell module 1 from above and insert it between the pair of claws 52a, and the solar cell module 1 that needs to be replaced due to deterioration over time can be easily replaced.

[0033] Furthermore, the wiring 21 extending from the solar cell module 1 and the wiring box 20 that houses the wiring 21 are housed within the cap board 120. This prevents the wiring 21 and wiring box 20 of the solar cell module 1 from being exposed to ultraviolet rays, thereby preventing deterioration of the wiring 21 and wiring box 20 of the solar cell module 1 due to ultraviolet rays.

[0034] Furthermore, the solar cell module 1 is formed in a rectangular shape when viewed from the front, and the gripping portion 52 grips either the long side or the short side of the solar cell module 1. This allows the solar cell module 1 to be attached in a state where it can easily receive sunlight, thereby improving power generation efficiency.

[0035] The solar cell module 1 also has a solar cell panel 11, and the outdoor surface of the solar cell panel 11 is covered with a transparent protective member 13. Therefore, the solar cell panel 11 is covered with the weather-resistant and transparent protective member 13. This prevents damage from flying objects and also prevents the solar cell panel 11 from being deteriorated by ultraviolet rays.

[0036] (Variation) Fig. 7(a) is a diagram showing a schematic example of an arrangement of solar cell modules 1A according to a first modified example. As shown in Fig. 7(a), the solar cell module 1A is formed in a rectangular shape when viewed from the front, and has a shape that is long in the vertical direction. Two solar cell modules 1A are arranged side by side on the balustrade wall 110.

[0037] For example, if the entire handrail wall 110 is sufficiently irradiated with sunlight, the solar cell module 1A will be sufficiently irradiated with sunlight at any position on the handrail wall 110, so it is sufficient to arrange the solar cell module 1A with a vertically elongated shape.

[0038] Fig. 7(b) is a diagram showing an example of the arrangement of solar cell modules 1B according to the first modification. As shown in Fig. 7(b), the solar cell module 1B is formed in a rectangular shape when viewed from the front, and has a shape that is long in the horizontal direction. Two solar cell modules 1B are arranged side by side on the balustrade wall 110.

[0039] For example, if the lower side of the handrail wall 110 is covered in shadow and does not receive sufficient sunlight, there is little practical benefit in placing the solar cell module 1B on the lower side of the handrail wall 110, and it is sufficient to place the solar cell module 1B, which has a horizontally elongated shape, on the upper side of the handrail wall 110.

[0040] The embodiments of the present invention have been described above in detail with reference to the drawings, but the specific configuration is not limited to the embodiments, and design changes that do not deviate from the gist of the present invention are included in the present invention.

[0041] For example, in the above embodiment, the pair of claws 52a grips the long side portions of the solar cell module 1, but if the solar cell module 1 has a rectangular shape that is long in the horizontal direction, the pair of claws 52a may grip the short side portions of the solar cell module 1. Furthermore, the shape of the solar cell module 1 is not limited to a rectangular shape, and may be a triangular shape, a square shape, or a polygonal shape with pentagons or more sides.
