Description

[Technical Field]

[0001] The present invention relates to a solar cell panel mounting structure and installation method. [Background technology]

[0002] Solar cell panels are known that are installed on roofs of ordinary houses, warehouses, buildings, gymnasiums, and other buildings to conserve electricity. This type of solar cell panel is configured as a module with multiple panels connected together. Conventionally, when solar cell panels are installed on roofs, for example, they are installed on metal stands assembled on the roof to ensure that they are not affected by unevenness in the roof and can adequately support the weight of the solar cell panel. Recently, flexible, sheet-shaped, and extremely lightweight solar cell panels have been developed, and these solar cell panels are installed on flat roof surfaces with adhesive (see, for example, Patent Document 1, etc.).

[0017] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a building 5 on which a solar cell panel 100 according to an embodiment of the present invention is installed. The building 5 may be, for example, a livestock barn such as a chicken coop or piggery, a warehouse, a factory, or the like, but is not limited to these. The building 5 has a roof 7 and exterior walls 9. The roof 7 in this embodiment is a gable roof, and is provided on both sides of a ridge 5M with a slope at a predetermined angle. The roof 7 is formed by joining multiple rectangular roof panels 1. Multiple roof panels 1 are joined in the width direction (girder direction), and two roof panels 1 are arranged side by side in the slope direction (flow direction).

[0018] FIG. 2 shows a cross section of the fixing structure at the joint of roof panels 1 adjacent in the width direction (horizontal direction).

[0019] The roof panel 1 is installed on a plurality of purlins 2, and the joint edge 1A on one end (right side) of the roof panel 1 shown on the left side in Fig. 2 is fixed to the purlins 2 with a screw 3. Then, the joint edge 1B on the other end (left side) of the roof panel 1 shown on the right side in Fig. 2 is joined to the joint edge 1A. In this way, the joint edge 1A on one end of the roof panel 1 is fixed with a screw 3, and the joint edge 1B on the other end is joined to the joint edge 1A of the fixed roof panel 1, and this process is repeated until a predetermined number of roof panels 1 are installed in the width direction.

[0020] The roof panel 1 is installed with its vertical direction (longitudinal direction) parallel to the slope direction. In other words, the roof panel 1 is installed so that the edges of the joint ends 1A and 1B extend in the slope direction. The purlins 2 are made of wood or metal channels.

[0021] As shown in Figure 2, roof panel 1 is a metal sandwich panel in which core material 30 made of a predetermined thickness of insulating material is sandwiched between front side surface material 10 and back side surface material 20, both of which are made of thin metal plates. Front side surface material 10 and back side surface material 20 are bonded to both sides of core material 30 with an adhesive. The adhesive is selected depending on the materials of front side surface material 10, back side surface material 20, and core material 30, and for example, a resin-based adhesive such as a urethane-based adhesive or an epoxy-based adhesive is used.

[0022] The material of front side surface material 10 and back side surface material 20 is not limited, but steel plate is suitable, and for example, a hot-dip 55% aluminum-zinc alloy plated steel plate (e.g., galvalume steel plate (registered trademark) such as color galvalume steel plate (registered trademark)) or other color steel plate is used. Front side surface material 10 and back side surface material 20 have a thickness that allows elastic deformation (e.g., approximately 0.35 mm). In this embodiment, of front side surface material 10 and back side surface material 20, at least front side surface material 10 is made of a magnetic metal.

[0023] The core material 30 is made of a lightweight resin foam material with heat insulating properties, such as polystyrene, but the material is not limited to this. The thickness of the core material 30 is, for example, 25 to 100 mm. The overall dimensions of the roof panel 1 are arbitrary and are determined to suit the roof to which it is to be installed, but examples include a vertical length of approximately 1800 to 13000 mm, a width of 400 to 1200 mm, and a thickness of approximately 25 to 300 mm.

[0024] As described above, the joint end 1A of the roof panel 1 is fixed to the purlin material 2 with a screw 3. As shown in Figure 2, the screw 3 penetrates the gutter-shaped portion 6 formed at the joint end 1A and the retaining clip 4, which is fitted into the gutter-shaped portion 6, and is then screwed into the purlin material 2 to fasten it in place. The hole through which the screw 3 penetrates is waterproofed with an appropriate sealing means to prevent water such as rainwater and melted snow from reaching the purlin material 2.

[0025] As shown in Figure 2, between roof panels 1, back-side engaging portion 43 of joint end 1A elastically engages with back-side engaging portion 44 of joint end 1B, and front-side engaging portion 45 of joint end 1B enters under and elastically engages with front-side engaging portion 41. The tip of front-side engaging portion 45 is pressed against waterproof sealing material 49, crimping and sealing. Caulking material 48 is filled in and seals the space between front-side engaging portions 41, 45. In this embodiment, a portion of joint end 1B overlaps the end of back surface material 20 on the back side of joint end 1A, covering the heads of screws 3, so that the heads of screws 3 are not exposed to the front surface (exterior).

[0026] The roof panel 1 constructed as described above has a surface (construction surface) 71 formed by the front side surface material 10 and a back surface 72 formed by the back side surface material 20. The entire surface of the front side surface 71 formed by the front side surface material 10 and the entire surface of the back surface 72 formed by the back side surface material 20 are both flat. "Flat" here means that the surfaces of the surface materials 10, 20 are not deformed into obvious irregularities (corrugated shapes) by bending, pressing, or the like, and remain in the flat state of the metal plate material. In this embodiment, at least the surface 71 of the front side surface material 10 is magnetic.

[0027] As shown in Figure 1, two roof panels 1 are installed side by side in the tilt direction on the roof 7 on one side of the ridge 5M. In the embodiment, the roof 7 is arranged such that the upper end of the lower roof panel 1 in the tilt direction overlaps the lower end of the upper roof panel 1 in the tilt direction. As a result, a step 8 exposed to the outside is formed at the transition point from the upper roof panel 1 to the lower roof panel 1, depending on the panel thickness.

[0028] As shown in FIG. 1, a building 5 of the embodiment has a plurality of solar cell panels 100 installed at arbitrary locations on a roof 7 and an exterior wall 9.

[0029] 3, the solar cell panel 100 of this embodiment is a flexible rectangular sheet-like object that can be bent or rolled by applying a certain degree of deformation force. This solar cell panel 100 has a well-known configuration, including a rectangular panel body 110 that is a power generation section in which a plurality of solar cells arranged in a matrix are laminated with a resin sheet, and a rectangular base sheet 120 attached to the back surface of the panel body 110. The base sheet 120 has a larger area than the panel body 110, and the four outer edges of the base sheet 120 extend beyond the four outer edges of the panel body 110.

[0030] The solar cell panel 100 is installed at any location on the surface 71 of the roof 7 and the wall surface 91 of the exterior wall 9. The surface 71 of the roof 7 and the wall surface 91 of the exterior wall 9 are construction surfaces on which the solar cell panel 100 is installed.

[0031] Fig. 4 is a plan view showing the state in which the solar cell panel 100 is attached to the surface 71 of the roof 7. Fig. 5 is a cross-sectional view taken along line VV in Fig. 4. As shown in Figs. 4 and 5, the solar cell panel 100 is installed by being attached to the surface 71 of the roof panel 1 by the magnetic force of a magnet 210.

[0032] The magnet 210 is a strip-shaped permanent magnet formed into a thin sheet. The magnet 210 has, for example, an adhesive surface on one side, and the adhesive surface is adhered to the back surface (mounting surface) 120a of the base sheet 120, which is the back surface of the solar cell panel 100. In this embodiment, the magnet 210 is arranged around the four peripheries of the back surface 120a of the base sheet 120, i.e., along almost the entire periphery of the outer edges of the four sides of the back surface 120a of the base sheet 120, and is attached to the back surface 120a. The magnet 210 is then attached to the surface 71 of the front side surface material 10 of the magnetic roof panel 1. In this way, the solar cell panel 100 is attached to the surface 71 of the roof panel 1 via the magnet 210.

[0033] The above is the mounting structure of the embodiment in which the solar cell panel 100 is mounted on the surface 71 of the front side material 10 of the roof panel 1 that constitutes the roof 7. The construction method for obtaining this mounting structure includes, for example, the following steps.

[0034] That is, first, magnets 210 are attached to the outer peripheral edge of the back surface 120a of the base sheet 120 of the solar cell panel 100. Here, if possible, magnets 210 may be attached to the surface 71 of the front side material 10 of the roof panel 1, or magnets 210 may be attached appropriately to both the solar cell panel 100 side and the roof panel 1 side so as not to overlap. Next, the solar cell panel 100 is attached to the surface 71 of the roof panel 1 via the magnets 210.

[0035] The above-described structure and method for mounting the solar cell panel 100 on the roof 7 can be similarly adopted when mounting the solar cell panel 100 on the wall surface 91 of the exterior wall 9. That is, the solar cell panel 100 is attached to the wall surface 91 with a magnet 210. The installation method is also the same as that for the roof 7 described above.

[0036] According to the embodiment, when performing maintenance such as repairs or element replacement on the solar cell panel 100 installed on the roof 7 or the exterior wall 9, the solar cell panel 100 can be removed from the installation surface. The solar cell panel 100 can be removed by peeling the solar cell panel 100 together with the magnet 210 from the installation surface against the magnetic force of the magnet 210.

[0037] In this way, the solar cell panel 100 can be removed from the roof 7 or the exterior wall 9, which makes removal easier than with conventional mounting structures in which the solar cell panel is attached with adhesive. This improves the ease of renovation. The power generation section of the removed solar cell panel 100 remains intact, so it can be reused as long as the power generation function is not impaired.

[0038] Figure 6 is a plan view showing a solar cell panel 100 attached to the surface 71 of a roof 7 using an attachment structure of another embodiment. Figure 7 is a cross-sectional view taken along line VII-VII in Figure 6. As shown in Figures 6 and 7, the solar cell panel 100 is attached to the surface 71 of the roof panel 1 by being affixed with a strip-shaped magnet 210 and by being crimped and joined with a plurality of rivets 250 (crimping members, joining members).

[0039] As in the above embodiment, the magnet 210 is arranged around almost the entire periphery of the back surface (mounting surface) 120a of the base sheet 120, which is the back surface of the solar cell panel 100, and is attached to the back surface 120a. The magnet 210 is then attached to the surface 71 of the front side surface material 10 of the roof panel 1.

[0040] The multiple rivets 250 are arranged at approximately equal intervals around the entire outer periphery of the solar cell panel 100. In the embodiment, the multiple rivets 250 are arranged corresponding to the magnets 210, and penetrate the base sheet 120 of the solar cell panel 100, the magnets 210, and the front side surface material 10 of the roof panel 1.

[0041] As shown in Fig. 8, rivet 250 is a so-called blind rivet. This rivet 250 includes a cylindrical member 251 having a flange 251a at the end on the front side (upper side in Fig. 8), and a shaft member 252 that passes through cylindrical member 251 and has a head 252a at the end on the back side (lower side in Fig. 8).

[0042] To crimp and join the solar cell panel 100 to the roof panel 1 using the rivet 250, as shown in FIG. 8(a), a pilot hole 260 is formed in the base sheet 120 of the solar cell panel 100, which is attached to the surface 71 of the roof panel 1 by the magnet 210, the magnet 210, and the front side surface material 10 of the roof panel 1, and the rivet 250 is inserted into the pilot hole 260 from the tip side (the head 252a side of the shaft member 252). The rivet 250 has a cylindrical member 251 and a shaft member 252 that pass through the pilot hole 260, so that the flange 251a can abut against the surface 71 of the roof panel 1, and the rear end of the cylindrical member 251 and the shaft member 252 protrude into the core member 30 inside the front side surface material 10. The shaft member 252 extends from the cylindrical member 251 toward the front side surface.

[0043] Next, using a predetermined pulling tool or the like, shaft member 252 is pulled toward the front surface side of roof 7 (above roof 7) while receiving a reaction force from flange 251a. As a result, as shown in FIGS. 8(b) and 8(c), head 252a of shaft member 252 crushes the end portion on the back surface side of tubular member 251, forming spherical engaging portion 251b, and base sheet 120 of solar cell panel 100, magnet 210, and front side surface material 10 of roof panel 1 are tightly sandwiched and maintained between engaging portion 251b and flange 251a. As a result, base sheet 120 of solar cell panel 100 is crimped and joined to front side surface material 10 of roof panel 1 with rivet 250. After crimping, shaft member 252 breaks in a manner such that the broken portion remains, for example, inside tubular member 251.

[0044] The above is the mounting structure of another embodiment in which the solar cell panel 100 is mounted on the surface 71 of the front side material 10 of the roof panel 1 that constitutes the roof 7. The construction method for obtaining this mounting structure is similar to the above embodiment in that the solar cell panel 100 is attached to the surface 71 of the roof panel 1 with the magnets 210, and then the base sheet 120 of the solar cell panel 100 is crimped and joined to the front side material 10 of the roof panel 1 with the rivets 250.

[0045] The mounting structure and construction method of the other embodiment in which the rivets 250 described above are added can be similarly employed when mounting the solar cell panel 100 on the wall surface 91 of the exterior wall 9. That is, the solar cell panel 100 is attached to the wall surface 91 with the magnets 210, and the base sheet 120 of the solar cell panel 100 is crimped and joined to the wall surface 91 with the rivets 250. The construction method is also the same as in the case of the roof 7 described above. Needless to say, in this case too, the wall surface 91 is made of a magnetic material such as a steel plate.

[0046] Even in this embodiment, when performing maintenance such as repairs or element replacement on the solar cell panel 100 installed on the roof 7 or exterior wall 9, the solar cell panel 100 can be removed from the installation surface. To remove the solar cell panel 100, the rivet 250 is pulled out and the solar cell panel 100 together with the magnet 210 is peeled off from the installation surface. In other words, the solar cell panel 100 is detachably crimped and joined to the installation surface by the rivet 250.

[0047] To remove the rivet 250, for example, the rotary blade of a drill or other drilling tool is rotated and embedded inside the tubular member 251 of the rivet 250 to unite the rotary blade with the tubular member 251, and then the tool is pulled up to remove the tubular member 251 from the front side surface material 10, the magnet 210, and the base sheet 120. Thereafter, the solar cell panel 100 together with the magnet 210 is peeled off from the installation surface.

[0048] In this way, the solar cell panel 100 can be removed from the roof 7 or the exterior wall 9, which makes removal easier than with conventional mounting structures in which the solar cell panel is attached with adhesive. This improves the ease of renovation. The power generation section of the removed solar cell panel 100 remains intact, so it can be reused as long as the power generation function is not impaired.

[0049] According to each of the above-described embodiments, the following effects are achieved. (1) The mounting structure for the solar cell panel 100 according to the embodiment is a structure for mounting the sheet-shaped solar cell panel 100 on a predetermined construction surface of the building 5 (surface 71 of the roof 7, wall surface 91 of the exterior wall 9, etc.), and is characterized in that the solar cell panel 100 is attached to the construction surface by the magnetic force of the magnet 210. This makes it easier to remove the solar cell panel 100 from the construction surface than before, improving the ease of renovation.

[0050] (2) In the mounting structure for the solar cell panel 100 according to the embodiment, the solar cell panel 100 is preferably detachably crimped to the mounting surface using a crimping member such as a rivet 250. This improves the mounting strength, and the mounted state of the solar cell panel 100 is maintained more safely.

[0051] (3) In the mounting structure for the solar cell panel 100 according to the embodiment, the magnet 210 is preferably formed in a strip shape and disposed along at least approximately the entire outer periphery of the back surface 120a, which is the mounting surface facing the installation surface of the solar cell panel 100. This makes it possible to easily prevent the solar cell panel 100 from peeling off or becoming detached from the installation surface, even in the event of strong winds, for example, and the installation state is maintained safely.

[0052] (4) In the mounting structure for the solar cell panel 100 according to the embodiment, it is preferable that a plurality of rivets 250 or other crimping members are arranged at predetermined intervals around at least approximately the entire periphery of the solar cell panel 100. This makes it possible to easily prevent the solar cell panel 100 from peeling off or becoming detached from the installation surface, even in the event of strong winds, for example, and the mounted state is maintained safely.

[0053] (5) In the mounting structure for the solar cell panel 100 according to the embodiment, it is preferable that the rivet 250 or other crimping member penetrates the magnet 210. This reduces the area required to fasten the solar cell panel 100 to the installation surface, thereby reducing the overall area of ​​the solar cell panel 100 without impairing power generation efficiency, and also maintaining the magnet 210 attached to the installation surface.

[0054] (6) In the mounting structure for the solar cell panel 100 according to the embodiment, the installation surface is provided on at least one of the roof 7 and the exterior wall 9. In other words, the solar cell panel 100 can be installed not only on the roof 7 but also on the exterior wall 9.

[0055] (7) The solar cell panel installation method according to the embodiment is an installation method for attaching a sheet-like solar cell panel 100 to a predetermined installation surface of a building 5 (such as the surface 71 of the roof 7 or the wall surface 91 of the exterior wall 9), and is characterized by comprising the steps of attaching a magnet 210 to at least one of the installation surface and the back surface 120a, which is the installation surface of the solar cell panel 100 facing the installation surface, and attaching the solar cell panel 100 to the installation surface via the magnet 210 by the magnetic force of the magnet 210. This makes it easier to remove the solar cell panel 100 from the installation surface than before, improving the ease of renovation.

[0056] (8) In the solar cell panel installation method according to the embodiment, after the step of attaching the solar cell panel to the installation surface via the magnet 210 by the magnetic force of the magnet 210, the solar cell panel 100 is further detachably crimped to the installation surface using a crimping member such as a rivet 250. This improves the installation strength, and the installed state of the solar cell panel 100 is maintained more safely.

[0057] (9) In the solar cell panel installation method according to the embodiment, the installation surface is provided on at least one of the roof 7 and the exterior wall 9. In other words, the solar cell panel 100 can be installed not only on the roof 7 but also on the exterior wall 9.

[0058] The above is an embodiment of the present invention, but the present invention is not limited to the above embodiment and can be modified within the scope of the present invention.

[0059] For example, the magnet 210 may be attached not only to the outer periphery of the rear surface 120a of the solar cell panel 100, but also to any position on the inside away from the outer periphery.

[0060] In the above embodiment, the rivet 250 is positioned in a position corresponding to the magnet 210 so as to penetrate the magnet 210, but the rivet 250 may also be positioned outside or inside the magnet 210 in a planar view of the solar cell panel 100, or both.

[0061] In the other embodiment described above, rivets 250 are used as the connecting members to be combined with magnets 210, but screws may be used as the connecting members instead of rivets 250. Suitable screws include, for example, tex screws such as "Tornado Point" manufactured by Yamahiro Co., Ltd. When screws are used, the screws are fastened using a fastening tool such as a screwdriver. When removing the solar cell panel 100 from the installation surface, the fastening tool is used to turn the screw in the opposite direction to when fastened, thereby loosening the screw and allowing it to be removed from the installation surface. In other words, the solar cell panel 100 can be detachably connected to the installation surface with the screws.

[0062] The solar cell panel 100 may be attached to the installation surface using a combination of a caulking member such as a rivet 250 and a screw. That is, the solar cell panel 100 may be detachably attached using at least one of a caulking member and a screw.

[0063] The roof 7 is made up of a plurality of roof panels 1, but may also be made up of a roof covered with metal plates such as steel plates or metal sheets.

[0064] The building on which the solar cell panel 100 is installed also includes a fence. [Explanation of symbols]
