Description

Panel holding device and panel holding method

The present invention relates to a panel holding device and a panel holding method.

Solar power generation has long been seen as a promising way to effectively utilize natural energy in response to environmental issues. Silicon (Si)-based solar cell modules are at the core of these technologies, and crystalline and thin-film solar cells are known as types of silicon power generation layers. In addition, a new type of solar cell that uses a material with a crystalline structure called perovskite is also attracting attention.

The technology described in Patent Documents 1 and 2 aims to easily add solar cell modules to existing transparent components, specifically transparent window glass.

The solar cell module of Patent Document 1 is formed by laminating, in that order, a transparent plate-like body, two or more translucent resin intermediate films, and a translucent film equipped with a translucent adhesive layer, with a photovoltaic cell disposed between the two or more resin intermediate films, and the adhesive layer adhered to an existing transparent member for installation. This makes it possible to retrofit the solar cell module by simply attaching it to an existing transparent member.

The solar cell module of Patent Document 2 comprises a solar cell module body configured with photovoltaic power generation cells arranged on the main surface of a transparent plate-like body, and a support member that supports the solar cell module body so that it faces an existing transparent member and supports it at a distance from the transparent member. This makes the solar cell module translucent, allowing it to be easily added to the existing transparent member.

Patent document 3 discloses an invention that relates to a method for attaching a solar cell module built into a substrate such as glass to a large glass surface.

However, in an installation method in which an adhesive layer of a solar cell module is adhered to an existing transparent member, as in Patent Document 1, it is not possible to completely prevent air from entering between the transparent member and the solar cell module during installation, and air bubbles remain between the transparent member and the solar cell module after installation. This causes a problem in that the appearance of the transparent member is deteriorated. In addition, when the entire surface of the solar cell module is directly adhered to the transparent member, it is difficult to remove the solar cell module from the transparent member, which makes it difficult to replace the solar cell module or restore the transparent member to its original state. In addition, the force generated during removal, i.e., the force used to peel the solar cell module body from the transparent member, may damage the solar cell module body or the transparent member.

In addition, in an installation method in which the solar cell module is spaced so as to face an existing transparent member, as in Patent Document 2, in order to attach a support member to the frame on which the transparent member is installed, complicated work such as drilling bolt holes in the frame on all four sides and installing wires is required. In addition, because the solar cell module is isolated from the transparent member, power generation efficiency may be worse than when it is located close to the transparent member.

Furthermore, in both Patent Documents 1 and 2, the wiring cords are exposed between adjacent solar cell modules, leaving room for improvement in terms of appearance.

Also, as shown in Figures 4 and 6 of Patent Document 3, if the solar cell module is surrounded by a frame on all four sides, it is difficult to remove the solar cell module from the frame after installation. Furthermore, if the ends of the solar cell module and the wiring are stored in the same groove, there is a risk that the wiring will be crushed or cut.

The above-mentioned problems are not limited to cases where solar cell modules are installed on existing transparent materials, but can also occur when panels with wiring cords (e.g., light-control glass, glass with built-in LEDs, heat-generating glass, glass with built-in blinds, flat-screen televisions, flat-screen LCD panels, etc.) are installed on existing transparent materials.

The present invention was made in consideration of these circumstances, and aims to provide a panel holding device and a panel holding method that allow panels to be easily added to existing transparent components with a good appearance.

The above object of the present invention can be achieved by the following configuration.

[First embodiment]
FIG 1 is a front view showing an example in which two solar cell modules are installed on an existing window glass using a panel holding device according to a first embodiment. FIG 2 is an exploded perspective view of the panel holding device and two solar cell modules. FIG 3 is a cross-sectional view taken along line III-III in FIG 1. FIG 4 is a cross-sectional view taken along line IV-IV in FIG 1. FIG 5 is a cross-sectional view taken along line V-V in FIG 1. In this specification, the direction of gravity and the up-down direction refer to the up-down direction in FIG 1. The front-back direction refers to the front-back direction of the window glass or the solar cell module, and is the depth direction of the paper in FIG 1. The left-right direction refers to the horizontal direction perpendicular to the direction of gravity and the front-back direction, and is the left-right direction in FIG 1.

As shown in Figures 1 to 5, in this embodiment, two solar cell modules 40 are installed on an existing transparent member, i.e., window glass 30, fixed to a frame portion 20 by a panel holding device 1. The panel holding device 1 has a holder 1A as a first support member and a pair of double-sided adhesive layer bodies 1B as a second support member. In this embodiment, the first support member of the panel holding device 1 is the holder 1A that is placed below the solar cell module 40 and supports the two solar cell modules 40, and the second support members are a pair of double-sided adhesive layer bodies 1B that are placed above the solar cell module 40 and support each of the two solar cell modules 40.

The frame section 20 comprises an upper frame 21 and a lower frame 23 that extend in the left-right direction, and a pair of left and right vertical frames 25, 25 that extend in the direction of gravity to connect the upper frame 21 and the lower frame 23.

The window glass 30 is a rectangular plate glass that is fitted and fixed into an opening surrounded by the upper frame 21, the lower frame 23, and a pair of vertical frames 25, 25. Specifically, the upper edge of the window glass 30 is fitted into a groove (not shown) formed in the upper frame 21, the lower edge is fitted into a groove (not shown) formed in the lower frame 23, and both left and right edges are fitted into grooves (not shown) formed in the pair of vertical frames 25, 25.

The existing transparent member is not limited to the window glass 30, but may be, for example, a transparent resin plate. Examples of transparent resin materials that make up the plate include polycarbonate and acrylic.

The holder 1A and double-sided adhesive layer 1B of the panel holding device 1 are arranged above and below or to the left and right of the existing window glass 30 with a gap between them.

In this embodiment, the holder 1A and the double-sided adhesive layer 1B are spaced apart from each other in the direction of gravity (the vertical direction in FIG. 1), with the holder 1A located on the lower side and the double-sided adhesive layer 1B located on the upper side. However, as will be described later with reference to FIG. 8, the holder 1A may be located on the upper side and the double-sided adhesive layer 1B on the lower side. Also, as will be described later with reference to FIG. 9, the holder 1A may be located on one side, left or right, and the double-sided adhesive layer 1B on the other side, left or right.

The holder 1A and the double-sided adhesive layer 1B are elongated members extending in the left-right direction parallel to the upper frame 21 and the lower frame 23 (see FIG. 1). In the illustrated example, the left-right dimension P of the holder 1A is greater than the sum of the left-right dimensions N of the solar cell modules 40, 2N (P>2N). Therefore, if only one solar cell module 40 is provided, P>N should be satisfied; if three solar cell modules 40 are provided, P>3N should be satisfied; and if n solar cell modules 40 are provided, P>nN should be satisfied.

As shown in Figures 1 to 5, the holder 1A of this embodiment includes a hollow tubular member 50 and a flat member 60 fixed to the window glass 30 side of the tubular member 50.

The holder 1A has a back surface 3 with an adhesive layer 2 that adheres to the surface of the existing window glass 30, a front surface 4 located on the opposite side of the back surface 3, an inner surface 5 (the upper surface when the holder 1A is placed on the lower side) that faces the double-sided adhesive layer 1B, and an outer surface 6 located on the opposite side of the inner surface 5 (the lower surface when the holder 1A is placed on the lower side).

The tubular member 50 is made of, for example, polyvinyl chloride (PVC) and includes a base portion 51 having an opening on the surface 4 side, and a lid portion 52 that closes the opening of the base portion 51. Note that the tubular member 50 is not limited to being made of two members, the base portion 51 and the lid portion 52, but may be made of a single tubular member.

The base portion 51 has a bottom portion 51a disposed on the window glass 30 side (rear surface 3 side), and a pair of walls 51b, 51b extending from both the upper and lower ends of the bottom portion 51a towards the front surface 4 side. An engaged portion 51d having a generally L-shaped cross section is provided on the mutually facing inner surfaces 51c of the pair of walls 51b, 51b. A protrusion 52a formed on the lid portion 52 engages with a groove formed between the inner surface 51c and the engaged portion 51d, thereby fixing the base portion 51 and the lid portion 52 together.

The positional relationship between the base portion 51 and the lid portion 52 may be reversed with respect to the window glass 30. That is, the tubular member 50 in Figures 3 to 5 may be rotated 180 degrees. In this case, the flat member 60 is fixed to the lid portion 52 instead of the base portion 51.

The holder 1A has a storage space 12 capable of storing the wiring cord 45 of the solar cell module 40. That is, the hollow internal space surrounded by the base portion 51 and the lid portion 52 of the tubular member 50 is the storage space 12. The storage space 12 has a generally rectangular cross section, and is formed over the entire longitudinal area of the holder 1A. That is, the storage space 12 passes through the holder 1A in the longitudinal direction.

As shown in the example, when the terminal box 46 is arranged on the lower surface of the solar cell module 40 and the wiring cord 45 is drawn from the terminal box 46, the holder 1A as the first support member is arranged below the solar cell module 40, and the double-sided adhesive layer 1B as the second support member is arranged above the solar cell module 40. Also, as described later using FIG. 8, when the terminal box 46 is arranged on the upper surface of the solar cell module 40 and the wiring cord 45 is drawn from the terminal box 46, the holder 1A as the first support member is arranged above the solar cell module 40, and the double-sided adhesive layer 1B as the second support member is arranged below the solar cell module 40. Also, as described later using FIG. 9, when the terminal box 46 is arranged on one of the left and right sides of the solar cell module 40 and the wiring cord 45 is drawn from the terminal box 46, the holder 1A as the first support member is arranged on one of the left and right sides of the solar cell module 40, and the double-sided adhesive layer 1B as the second support member is arranged on the other left and right sides of the solar cell module 40.

The flat plate member 60 is fixed to the bottom 51a of the base portion 51 by screws 70. Note that the method of fixing the flat plate member 60 to the tubular member 50 is not limited to screw fixing, and may be selected arbitrarily, such as adhesive fixing.

The flat plate member 60 is a flat plate-like member extending in the longitudinal direction of the holder 1A, and is made of aluminum, for example. The vertical dimension of the flat plate member 60 is smaller than the vertical dimension of the tubular member 50, and therefore a first groove portion 7 and a second groove portion 8 are formed above and below the flat plate member 60, as described below.

The back surface of the flat plate member 60 constitutes the back surface 3 of the holder 1A. The back surface 3 is a flat surface whose vertical dimension is smaller than that of the front surface 4, and an adhesive layer 2 is provided on the back surface 3. The adhesive layer 2 is not particularly limited as long as it has an adhesive function, but for example, an acrylic foam double-sided tape can be used. Examples of acrylic foam double-sided tape include VHB (registered trademark) tape and Hyper Joint (registered trademark).

The flat member 60 has an inner surface 61 (upper surface when the holder 1A is placed on the lower side) which faces the double-sided adhesive layer 1B, and an outer surface 63 (lower surface when the holder 1A is placed on the lower side) located on the opposite side to the inner surface 61. The inner surface 61 of the flat member 60 and the base portion 51 of the tubular member 50 define a first groove portion 7. The first groove portion 7 is formed between the holder 1A and the existing window glass 30, and is capable of accommodating the lower end portion of the solar cell module 40. The first groove portion 7 has a rectangular cross section that matches the shape of the solar cell module 40, and is formed over the entire longitudinal area of the holder 1A. In other words, the first groove portion 7 passes through the holder 1A in the longitudinal direction.

As shown in FIG. 5, adhesive A1 may be filled into the first groove 7 in the portion where the lower end of the solar cell module 40 is not housed (for example, the portion between adjacent solar cell modules 40, 40, or the portion between the solar cell module 40 and the vertical frame 25). The adhesive A1 is preferably suitable for bonding a polyvinyl chloride tubular member 50, an aluminum flat member 60, and the window glass 30, and examples of such adhesive include silicone-based sealants and modified silicone-based sealants. The adhesive A1 has a function of bonding and fixing the holder 1A and the window glass 30, and a sealing function of preventing dust and water from entering the first groove 7.

The outer surface 63 of the flat member 60 and the base portion 51 of the tubular member 50 define a second groove portion 8. The second groove portion 8 is formed between the holder 1A and the existing window glass 30. That is, the holder 1A has the second groove portion 8 on the opposite side to the first groove portion 7 across the adhesive layer 2 (rear surface 3). The second groove portion 8 has a rectangular cross section and is formed over the entire longitudinal area of the holder 1A. That is, the second groove portion 8 penetrates the holder 1A in the longitudinal direction.

As shown in FIG. 5, the second groove 8 may be filled with adhesive A2. Note that the adhesive A2 is not shown in FIGS. 3 and 4. The adhesive A2 filled in the second groove 8 bonds the holder 1A to the window glass 30. The adhesive A2 is preferably suitable for bonding the polyvinyl chloride tubular member 50, the aluminum flat plate member 60, and the window glass 30, and examples of the adhesive A2 include silicone-based sealant and modified silicone-based sealant. The adhesive A2 has a function of bonding and fixing the holder 1A to the window glass 30, and a sealing function of preventing dust and water from entering the second groove 8.

The weight of the solar cell module 40 is applied to the holder 1A. Therefore, the holder 1A may be supported from below by the first weight-receiving member 17 and/or the second weight-receiving member 18 so that the holder 1A can withstand the weight.

In the example of FIG. 1, two first weight receiving members 17 that support holder 1A are provided on lower frame 23, spaced apart in the left-right direction. First weight receiving member 17 is fixed to lower frame 23 by fixing means (e.g., screws, adhesive, etc.) not shown, and is a plate-shaped member that extends upward toward holder 1A. The tip of first weight receiving member 17 abuts against the underside of holder 1A, supporting holder 1A. The shape of first weight receiving member 17 is not particularly limited and may be set arbitrarily.

Furthermore, a second weight support member 18 that supports the holder 1A is provided on each of the pair of vertical frames 25. The second weight support member 18 is a plate-shaped member that is fixed to the vertical frames 25 by fixing means (e.g., screws, adhesive, etc.) not shown. The second weight support member 18 abuts against the underside of the holder 1A and supports the holder 1A. The second weight support member 18 may be provided on only one of the pair of vertical frames 25, rather than on both. The shape of the second weight support member 18 is not particularly limited and may be set arbitrarily. The holder 1A may also be placed directly on the lower frame 23, in which case the first weight support member 17 and the second support member 18 can be omitted.

Although not shown, a wire may be provided between the pair of vertical frames 25 as an extension member that extends in the left-right direction to connect the pair of vertical frames 25 and supports the holder 1A. The wire can be stored in the storage space 12. The extension member is not limited to a wire, and any other member such as a pipe may be used as long as it extends in the left-right direction between the pair of vertical frames 25 to connect the pair of vertical frames 25 and supports the holder 1A.

The solar cell module 40 is, for example, a superstrate type solar cell module, and is made by sandwiching multiple cells 47 sealed with a filler between a front cover on the light receiving side (window glass 30 side) and a back cover made of weather-resistant film. The edges of the solar cell module 40 are covered with an edge cover made of rubber such as ethylene propylene diene rubber (EPDM) for waterproofing and dustproofing.

In this embodiment, the underside of the solar cell module 40 has a terminal box 46 to which the end of the interconnector 48 is connected. By arranging the terminal box 46 in this way, the solar cell module 40 can be made thin. The terminal box 46 may be provided on any surface of the solar cell module 40, not just the underside, and may be provided on the top, left, or right surface. Although not shown, the terminal box 46 may be provided in a position that overlaps with the cells 47 of the solar cell module 40 in the front-back direction.

2 to 4, there is a gap between the lower end of the solar cell module 40 and the bottom of the first groove portion 7 of the holder 1A in the vertical direction. A terminal box 46 and a setting block 44 are arranged in this gap. In this embodiment, a pair of setting blocks 44 are arranged on both the left and right sides of the terminal box 46. The setting blocks 44 are made of rubber such as ethylene propylene diene rubber (EPDM), and are arranged so as to fill the gap between the lower end of the solar cell module 40 and the bottom of the first groove portion 7 of the holder 1A. As a result, the lower end of the solar cell module 40 is supported by the bottom of the first groove portion 7 via the setting block 44. The vertical dimension of the setting block 44 is set to be larger than the vertical dimension of the terminal box 46. Therefore, as shown in FIG. 3, a gap exists between the terminal box 46 stored in the first groove portion 7 and the flat plate member 60 located below the terminal box 46, and the terminal box 46 does not come into contact with the bottom of the first groove portion 7, preventing a load from being applied to the terminal box 46.

As shown in FIG. 3, the terminal box 46 of this embodiment has a thickness in the front-back direction (left-right direction in FIG. 3) that is greater than the thickness of the solar cell module 40. The terminal box 46 protrudes toward the window glass 30 side and the tubular member 50 side in the front-back direction beyond the solar cell module 40. In FIG. 3, the protrusion amount of the protruding portion 46a of the terminal box 46 toward the window glass 30 side in the front-back direction is indicated by the symbol A. In addition, a gap of dimension B is interposed in the front-back direction between the protruding portion 46a of the terminal box 46 and the window glass 30. The sum A+B of the protruding amount A and the dimension B is equal to the thickness C of the double-sided adhesive layer 1B in the front-back direction and the dimension D of the gap between the window glass 30 and the solar cell module 40 (A+B=C=D). In other words, by increasing or decreasing the thickness C of the double-sided adhesive layer 1B in the front-back direction, the dimension D (D=C) of the gap between the window glass 30 and the solar cell module 40 can be increased or decreased. In order for the terminal box 46 not to come into contact with the window glass 30 and for the solar cell module 40 to be positioned parallel to the window glass 30, the thickness C in the front-back direction of the double-sided adhesive layer 1B must be greater than the protrusion amount A of the protruding portion 46a of the terminal box 46 (C>A).

As shown in FIG. 3, a wiring cord 45 for outputting electricity generated by the solar cell module 40 to the outside is connected to the terminal box 46. The wiring cord 45 is connected, for example, to both sides of the terminal box 46 in the longitudinal direction (depth direction on the paper in FIG. 3). The terminal boxes 46, 46 of adjacent solar cell modules 40, 40 are connected in series via the wiring cord 45.

Although not shown, a notch (opening) is provided in the base portion 51 in the vertical direction between the flat plate member 60 and the engaged portion 51d. The wiring cord 45 pulled out from the terminal box 46 is stored in the storage space 12 through this notch. The storage space 12 is covered by the base portion 51 and the lid portion 52 except for the area where the notch is provided, so the base portion 51 and the lid portion 52 can be said to be a cover for the storage space 12. The wiring cord 45 is connected to the wiring cord 45 pulled out from the terminal box 46 of another solar cell module 40 inside the storage space 12.

In this way, the wiring cord 45 is stored in the storage space 12 of the holder 1A as the first support member and is not exposed to the outside, so when viewed from the front as shown in Figures 1 and 2, the wiring cord 45 is not exposed between adjacent solar cell modules 40, 40, which gives a good appearance. Furthermore, since a cover (base portion 51 and lid portion 52) is provided on the storage space 12, the wiring cord 45 inside the storage space 12 is not exposed, which gives a good appearance. In addition, the cover prevents water, dust, etc. from entering the storage space 12.

In addition, the panel with the wiring cord is not limited to the solar cell module 40 described above, but may be any plate-shaped body to which a wiring cord is connected, such as light-control glass, glass with built-in LEDs, heat-generating glass, glass with built-in blinds, flat-screen televisions, and flat-screen LCD panels.

As shown in Figures 3 and 4, the double-sided adhesive layer 1B serving as the second support member is an elongated member extending in the left-right direction parallel to the upper frame 21 and the lower frame 23 (see Figure 1). In this embodiment, as shown in Figure 1, the left-right dimension of the double-sided adhesive layer 1B is approximately equal to the left-right dimension N of the solar cell module 40. However, the left-right dimension of the double-sided adhesive layer 1B is not particularly limited. However, from the viewpoint of improving the appearance by making the double-sided adhesive layer 1B invisible from the outside, it is preferable that the left-right dimension of the double-sided adhesive layer 1B be equal to or less than the left-right dimension N of the solar cell module 40.

The double-sided adhesive layer 1B has an adhesive layer 15 that adheres to the existing window glass 30, and also restricts movement of the solar cell module 40 in the out-of-plane direction (directions perpendicular to the up-down and left-right directions; front-to-back directions).

More specifically, the double-sided adhesive layer 1B comprises a flat plate portion 14 extending in the left-right direction (longitudinal direction), an adhesive layer 15 provided on the surface of the plate portion 14 facing the window glass 30 and adhering to the window glass 30, and an adhesive layer 16 provided on the surface of the plate portion 14 facing the solar cell module 40 and adhering to the solar cell module 40.

The material of the plate portion 14 is not particularly limited, but examples include polycarbonate, acrylic, aluminum, etc. Also, acrylic foam double-sided tape can be used for the adhesive layers 15 and 16. Examples of acrylic foam double-sided tape include VHB (registered trademark) tape and Hyper Joint (registered trademark).

As described above with reference to Figure 3, the thickness C of the double-sided adhesive layer 1B in the front-to-back direction is equal to the sum of the protrusion amount A of the protrusion 46a of the terminal box 46 and the dimension B of the gap between the protrusion 46a of the terminal box 46 and the window glass 30 (C = A + B). Therefore, the solar cell module 40 can be installed parallel to the window glass 30 and can be positioned vertically to the ground.

In this embodiment, the double-sided adhesive layer 1B is disposed at a position slightly displaced downward from the upper edge of the solar cell module 40 as shown in Figs. 3 and 4, but the position of the double-sided adhesive layer 1B is not particularly limited. That is, when the holder 1A is disposed below the solar cell module 40 as in this embodiment, the double-sided adhesive layer 1B may be disposed at any position as long as it does not interfere with the holder 1A, the cells 47, etc. That is, the double-sided adhesive layer 1B may be disposed at the left end or the right end of the solar cell module 40. Regardless of the location, the double-sided adhesive layer 1B can restrict the out-of-plane movement of the solar cell module 40, but from the viewpoint of effectively restricting the movement, it is preferable to place it at the upper end of the solar cell module 40 as in the illustrated example.

The solar cell module 40 as described above is installed on the window glass 30 using the panel holding device 1 (holder 1A and double-sided adhesive layer 1B) in the manner described below.

The holder 1A is adhered to the window glass 30. Adhesion is performed by pressing the adhesive layer 2 provided on the back surface 3 of the flat member 60 of the holder 1A towards the window glass 30. If the first weight receiving member 17 and the second weight receiving member 18 are provided (see FIG. 1), the holder 1A is positioned so that its underside is supported by the first weight receiving member 17 and the second weight receiving member 18. If the holder 1A is placed directly on the lower frame 23, the first weight receiving member 17 and the second weight receiving member 18 can be omitted.

5, adhesive A1 is filled into the first groove 7 of the holder 1A in the portion where the lower end 43 of the solar cell module 40 is not housed (for example, the portion between adjacent solar cell modules 40, 40, or the portion between the solar cell module 40 and the vertical frame 25). Adhesive A2 is filled into the second groove 8. Note that the holder 1A of this embodiment only needs to be adhered to the window glass 30 by at least the adhesive layer 2, and as long as the desired adhesive strength can be satisfied by adhesion by the adhesive layer 2, it is not necessary to adhere by the adhesives A1 and A2 filled into the first groove 7 and/or second groove 8.

After the holder 1A is adhesively fixed to the window glass 30 as described above, the lower end of the solar cell module 40 is stored in the first groove portion 7 of the holder 1A. The solar cell module 40 is stored by dropping the lower end into the first groove portion 7 of the holder 1A.

There is a gap between the lower end of the solar cell module 40 and the bottom of the first groove portion 7 in the vertical direction, and a setting block 44 is placed in this gap beforehand. Therefore, the lower end of the solar cell module 40 stored in the first groove portion 7 is supported by the setting block 44.

The terminal box 46 of the solar cell module 40 is stored in the first groove 7 so as to be adjacent to the setting block 44 in the left-right direction. The wiring cord 45 drawn out from the terminal box 46 of the solar cell module 40 is stored in the storage space 12 of the holder 1A.

Then, the upper end of the solar cell module 40 is adhered and fixed to the window glass 30 using the double-sided adhesive layer 1B. This adhesion and fixation may be performed by (i) adhering the double-sided adhesive layer 1B to the window glass 30 in advance and then pressing the solar cell module 40 against the double-sided adhesive layer 1B, or (ii) adhering the double-sided adhesive layer 1B to the solar cell module 40 in advance and then pressing the solar cell module 40 with the double-sided adhesive layer 1B integrated therewith against the window glass 30.

By using the simple process described above, it is possible to add a solar cell module 40 to the window glass 30.

As described above, according to the first embodiment of the present invention, the holder 1A comprises an adhesive layer 2 that adheres to the existing window glass 30, a first groove portion 7 capable of accommodating an end of the solar cell module 40, and a storage space portion 12 capable of accommodating the wiring cord 45, and the double-sided adhesive layer 1B comprises an adhesive layer 15 that adheres to the existing window glass 30 and restricts movement of the solar cell module 40 in an out-of-plane direction.
Therefore, it is possible to provide a panel holding device 1 and a panel holding method that enable the solar cell module 40 to be easily and attractively added to an existing window glass 30 .
That is, in this embodiment, unlike Patent Document 1, an adhesive layer is not provided on the solar cell module, but the holder 1A and the double-sided adhesive layer 1B are provided with adhesive layers 2, 15. Therefore, the solar cell module 40 is only in contact with the window glass 30 or faces the window glass 30 with a small gap therebetween, so no air bubbles are generated between the solar cell module 40 and the window glass 30, and the appearance is good.
Furthermore, when restoring the window glass 30 to its original state, the holder 1A and the double-sided adhesive layer 1B are removed from the window glass 30, and the solar cell module 40 is removed from the holder 1A and the double-sided adhesive layer 1B. Therefore, unlike Patent Document 1, it is not necessary to peel off the entire solar cell module 40 from the window glass 30, and it is sufficient to peel off only the holder 1A and the double-sided adhesive layer 1B, which simplifies the work of restoring the window glass 30 to its original state and reduces the possibility of damage to the window glass 30 and the solar cell module 40.
In addition, since there is no need for complicated construction such as drilling bolt holes in frame members and installing wires as described in Patent Document 2, it is possible to easily install additional solar cell modules 40. Furthermore, unlike Patent Document 2, the solar cell modules 40 face closely to the window glass 30, so that deterioration of power generation efficiency caused by the solar cell modules 40 being separated from the window glass 30 can be prevented.
In addition, since the wiring cord 45 of the solar cell module 40 is stored in the storage space 12 of the holder 1A, it is not exposed between adjacent solar cell modules 40 or between the solar cell module 40 and the vertical frame 25, resulting in a good appearance.

The double-sided adhesive layer 1B serving as the second support member further includes an adhesive layer 16 that adheres to the solar cell module 40. In this way, the solar cell module 40 can be easily fixed to the window glass 30 by double-sided adhesion. Furthermore, the double-sided adhesive layer 1B is placed between the solar cell module 40 and the window glass 30 and is difficult to see from the outside, so it has a good appearance.

In addition, the solar cell module 40 has a terminal box 46 arranged on the underside of the solar cell module 40, which is the surface on the holder 1A side, and a wiring cord 45 is connected to the terminal box 46. The terminal box 46 is stored in the first groove portion 7 of the holder 1A.
Therefore, when viewed from the front as shown in FIG. 1, neither the wiring cord 45 nor the terminal box 46 are exposed to the outside, providing a good appearance.

In addition, the terminal box 46 has a protruding portion 46a that protrudes a protruding amount A beyond the panel toward the existing window glass 30 in the front-to-back direction, and a gap of dimension B is interposed in the front-to-back direction between the protruding portion 46a of the terminal box 46 and the existing window glass 30, and the thickness C of the double-sided adhesive layer 1B in the front-to-back direction is equal to the sum of the protruding amount A of the terminal box and the gap dimension B (C = A + B)).
Therefore, the solar cell module 40 can be installed parallel to the window glass 30 and can be arranged vertically with respect to the ground.

In addition, the storage space 12 is provided with a cover (a base portion 51 and a lid portion 52).
Therefore, the wiring cord 45 is not exposed to the outside, and the appearance is excellent. In addition, the cover prevents water, dust, etc. from entering the storage space 12.

In addition, adhesive A1 is filled in the first groove portion 7 of the holder 1A in the portion where the lower end portion of the solar cell module 40 is not accommodated (for example, the portion between adjacent solar cell modules 40, 40, or the portion between the solar cell module 40 and the vertical frame 25).
Therefore, the adhesive A1 can firmly bond and fix the holder 1A and the window glass 30 together, and also prevents dust and water from entering the first groove portion 7.

In addition, if the tensile shear adhesive strength of adhesive layer 15 of double-sided adhesive layer 1B is P1 (unit: MPa), the tensile shear adhesive strength of adhesive layer 16 of double-sided adhesive layer 1B is P2 (unit: MPa), the specific gravity of solar cell module 40 is K, the thickness of solar cell module 40 is T (unit: mm), the area of solar cell module 40 is S1, the adhesive area of adhesive layer 15 of double-sided adhesive layer 1B is S2, the adhesive area of adhesive layer 16 of double-sided adhesive layer 1B is S3, and the acceleration of gravity is G, then it is preferable that P1 ≧ (1× ^10-6 × K・T・G・S1)/S2, and it is preferable that P2 ≧ (1× ^10-6 × K・T・G・S1)/S3.

Here, the tensile shear adhesive strengths P1, P2 of the adhesive layers 15, 16 of the double-sided adhesive layer 1B are values that can be measured based on the "Test method for tensile shear adhesive strength of rigid adherends" defined in the Japanese Industrial Standard JIS K6850:1999. The thickness T is the thickness of the solar cell module 40 in the front-back direction. The area S1 is the area of the solar cell module 40 as viewed from the front-back direction. The adhesive area S2 is the area of the adhesive layer 15 as viewed from the front-back direction. The adhesive area S3 is the area of the adhesive layer 16 as viewed from the front-back direction.

In the above inequality, (1×10 ⁻⁶ ×K・T・G・S1)/S2 on the right side corresponds to the shear force generated in the adhesive layer 15 by the weight of the solar cell module 40, and (1×10 ⁻⁶ ×K・T・G・S1)/S3 corresponds to the shear force generated in the adhesive layer 16 by the weight of the solar cell module 40. Therefore, as described above, by satisfying P1≧(1×10 ⁻⁶ ×K・T・G・S1)/S2 and P2≧(1×10 ⁻⁶ ×K・T・G・S1)/S3, the tensile shear adhesive strengths P1, P2 exceed the shear force generated in the adhesive layers 15, 16 by the weight of the solar cell module 40, and therefore it is possible to prevent the double-sided adhesive layer 1B from shifting or peeling off.

Furthermore, it is more preferable that the tensile shear bond strengths P1 and P2 are P1 ≧ 0.100 and P2 ≧ 0.100, and it is even more preferable that P1 ≧ 0.500 and P2 ≧ 0.500. This is to reduce the risk of strength reduction due to environmental conditions.

The following Examples 1 to 3 are used to consider desirable values for the tensile shear adhesive strengths P1 and P2 of adhesive layers 15 and 16.

[Example 1]
The various values in Example 1 are as follows:
Tensile shear adhesive strength P1, P2 of adhesive layers 15, 16: 0.590 (unit: MPa)
Specific gravity K of the solar cell module 40: 2.5
Thickness T of the solar cell module 40: 3 (unit: mm)
Gravitational acceleration G: 9.80665 (unit: m/s ² ):
Area S1 of the solar cell module 40: 1.6 (unit: m ² )
Adhesive areas S2 and S3 of adhesive layers 15 and 16: 0.005 (unit: m ² )

In Example 1, the shear force generated in the adhesive layers 15, 16 by the weight of the solar cell module 40 is (1×10 ⁻⁶ ×K.T.G.S1)/S2=(1×10 ⁻⁶ ×K.T.G.S1)/S3=0.0235. The tensile shear bond strengths P2, P3 of the adhesive layers 15, 16 are 0.590, which is greater than 0.0235, and therefore satisfy the required tensile shear bond strengths derived from P1≧(1×10 ⁻⁶ ×K.T.G.S1)/S2 and P2≧(1×10 ⁻⁶ ×K.T.G.S1)/S3, and the double-sided adhesive layer 1B can be prevented from shifting or peeling off.

[Example 2]
Various values in Example 2 are as follows. Values other than P1 and P2 are the same as in Example 1.
Tensile shear adhesive strength P1, P2 of adhesive layers 15, 16: 0.020 (unit: MPa)
Specific gravity K of the solar cell module 40: 2.5
Thickness T of the solar cell module 40: 3 (unit: mm)
Gravitational acceleration G: 9.80665 (unit: m/s ² ):
Area S1 of the solar cell module 40: 1.6 (unit: m ² )
Adhesive areas S2 and S3 of adhesive layers 15 and 16: 0.005 (unit: m ² )

In Example 2, the shear force generated in the adhesive layers 15, 16 by the weight of the solar cell module 40 is (1×10 ⁻⁶ ×K.T.G.S1)/S2=(1×10 ⁻⁶ ×K.T.G.S1)/S3=0.0235. The tensile shear adhesive strengths P2, P3 of the adhesive layers 15, 16 are 0.020, which is less than 0.0235, and therefore do not satisfy the required tensile shear adhesive strengths derived from P1≧(1×10 ⁻⁶ ×K.T.G.S1)/S2 or P2≧(1×10 ⁻⁶ ×K.T.G.S1)/S3, and the double-sided adhesive layer 1B may shift or peel off.

[Example 3]
Various values in Example 3 are as follows. Values other than S2 and S3 are the same as in Example 1.
Tensile shear adhesive strength P1, P2 of adhesive layers 15, 16: 0.590 (unit: MPa)
Specific gravity K of the solar cell module 40: 2.5
Thickness T of the solar cell module 40: 3 (unit: mm)
Gravitational acceleration G: 9.80665 (unit: m/s ² ):
Area S1 of the solar cell module 40: 1.6 (unit: m ² )
Adhesive areas S2 and S3 of adhesive layers 15 and 16: 0.00015 (unit: m ² )

In Example 3, the shear force generated in the adhesive layers 15, 16 by the weight of the solar cell module 40 is (1×10 ⁻⁶ ×K.T.G.S1)/S2=(1×10 ⁻⁶ ×K.T.G.S1)/S3=0.785. The tensile shear adhesive strengths P2, P3 of the adhesive layers 15, 16 are 0.590, which is less than 0.785, and therefore do not satisfy the required tensile shear adhesive strengths derived from P1≧(1×10 ⁻⁶ ×K.T.G.S1)/S2 or P2≧(1×10 ⁻⁶ ×K.T.G.S1)/S3, and the double-sided adhesive layer 1B may shift or peel off.

[Modification of the first embodiment]
In addition, the second support member is not limited to the double-sided adhesive layer 1B as described above, so long as it has an adhesive layer 15 that adheres to the existing window glass 30 and restricts movement of the solar cell module 40 in the out-of-plane direction (directions perpendicular to the up-down and left-right directions; front-to-back directions).

FIG. 6 is a diagram corresponding to FIG. 2 in a modified example of the first embodiment. FIG. 7 is a diagram corresponding to FIG. 3 in a modified example of the first embodiment. As shown in FIGS. 6 and 7, in this embodiment, instead of the double-sided adhesive layer 1B as the second support member, an adhesive layer 15 that adheres to the existing window glass 30 is provided, and a vibration prevention member 1C that restricts the movement of the solar cell module 40 in the out-of-plane direction is used.

As shown in Figures 6 and 7, the upper end of the solar cell module 40 is housed in a groove 9 provided in the anti-vibration member 1C to prevent vibration. The anti-vibration member 1C is a member that extends in the left-right direction (longitudinal direction) and is made of, for example, polyvinyl chloride (PVC). An adhesive layer 15 is provided on the surface of the anti-vibration member 1C facing the window glass 30.

The anti-vibration member 1C has a groove 9 recessed upward from approximately the center in the front-to-back direction on the underside. This groove 9 is a through hole that passes through the anti-vibration member 1C in the longitudinal direction. Therefore, the anti-vibration member 1C is formed with a cross section that is approximately an inverted U-shape with the opening of the first groove 7 on the underside.

The shape of the groove 9 of the anti-vibration member 1C is set to be approximately the same as or slightly larger than the shape of the upper end of the solar cell module 40. Then, the upper end of the solar cell module 40 is stored in the groove 9 of the anti-vibration member 1C, and the anti-vibration member 1C is pressed against the window glass 30, thereby adhesively fixing the solar cell module 40 to the window glass 30.

In this way, the solar cell module 40 can be fixed to the window glass 30 by the anti-vibration member 1C having the adhesive layer 15. In particular, the anti-vibration member 1C clamps the solar cell module 40 stored in the groove portion 9 from the front and back directions, so that it can effectively restrict the movement of the solar cell module 40 in the out-of-plane direction.

[Second embodiment]
FIG. 8 is a front view showing an example in which two solar cell modules are installed on an existing window pane by the panel holding device according to the second embodiment.

As shown in FIG. 8, the panel holding device 1 of this embodiment has a holder 1A that is placed above the solar cell module 40 on the existing window glass 30, and a pair of double-sided adhesive layers 1B, 1B that are placed below the solar cell module 40 on the existing window glass 30. In other words, the holder 1A and pair of double-sided adhesive layers 1B, 1B of the second embodiment are the holder 1A and pair of double-sided adhesive layers 1B, 1B of the first embodiment rotated 180° on the plane in which the window glass 30 and the solar cell module 40 extend. Therefore, detailed explanations of the structures of the holder 1A and double-sided adhesive layer 1B will be omitted.

In this embodiment, the terminal box 46 protrudes upward from the upper edge of the solar cell module 40. To accommodate this terminal box 46, the holder 1A is placed above the solar cell module 40. Note that the setting block 44 that was placed in the first groove portion 7 of the holder 1A in the first embodiment is not provided in this embodiment. This is because the weight of the solar cell module 40 is not applied to the holder 1A that is placed above.

The weight of the solar cell module 40 is supported by the double-sided adhesive layer 1B disposed below. The solar cell module 40 may be placed directly on the lower frame 23, in which case the weight of the solar cell module 40 is also supported by the lower frame 23.

According to the second embodiment, similarly to the first embodiment, the holder 1A comprises an adhesive layer 2 that adheres to the existing window glass 30, a first groove portion 7 capable of accommodating an end of the solar cell module 40, and a storage space portion 12 capable of accommodating the wiring cord 45, and the double-sided adhesive layer 1B comprises an adhesive layer 15 that adheres to the existing window glass 30 and restricts movement of the solar cell module 40 in the out-of-plane direction.
Therefore, it is possible to provide a panel holding device 1 and a panel holding method that allow the solar cell module 40 to be easily and attractively added to an existing window glass 30. Other effects are also similar to those of the first embodiment.

[Third embodiment]
FIG. 9 is a front view showing an example in which two solar cell modules are mounted on an existing window pane by means of a panel holding device according to the third embodiment.

As shown in FIG. 9, the panel holding device 1 of this embodiment has a holder 1A that is positioned to the left of the solar cell module 40 on the existing window glass 30, and a pair of double-sided adhesive layers 1B, 1B that are positioned to the right of the solar cell module 40 on the existing window glass 30.

The holder 1A of this embodiment is the holder 1A and the pair of double-sided adhesive layers 1B, 1B of the first embodiment rotated 90° clockwise in the plane in which the window glass 30 and the solar cell module 40 extend. Therefore, detailed explanations of the structures of the holder 1A and the double-sided adhesive layer 1B are omitted.

In this embodiment, the terminal box 46 protrudes leftward from the left edge of the solar cell module 40. To accommodate this terminal box 46, the holder 1A is positioned to the left of the solar cell module 40.

The lower of the two solar cell modules 40 may be placed directly on the lower frame 23, in which case the weight of that solar cell module 40 is supported by the lower frame 23. The weight of the two solar cell modules 40 is also supported by the adhesive strength of the double-sided adhesive layers 1B, 1B.

According to the third embodiment, similarly to the first embodiment, the holder 1A comprises an adhesive layer 2 that adheres to the existing window glass 30, a first groove portion 7 capable of accommodating an end of the solar cell module 40, and a storage space portion 12 capable of accommodating the wiring cord 45, and the double-sided adhesive layer 1B comprises an adhesive layer 15 that adheres to the existing window glass 30 and restricts movement of the solar cell module 40 in the out-of-plane direction.
Therefore, it is possible to provide a panel holding device 1 and a panel holding method that allow the solar cell module 40 to be easily and attractively added to an existing window glass 30. Other effects are also similar to those of the first embodiment.
