  The present invention relates to a sheet waterproof solar power generation panel set capable of performing sheet waterproofing construction while installing a solar power generation panel, its construction method and construction structure.

  When a solar power generation system is adopted for a building, for example, as shown in FIG. 16, a pedestal (65) is fixed to the roof material of the building, and a solar power generation panel (60) is attached on the pedestal (65). It is common. However, in this panel mounting structure, a fixing tool such as an anchor nail is passed through the roofing material and fixed to the base for fixing the gantry.

  FIG.1 and FIG.2 is a figure which shows the sheet | seat waterproofing type photovoltaic power generation panel set (1) which is embodiment of this invention. As shown to both figures, this panel set (1) is provided with three photovoltaic power generation panels (10) and the connection sheet | seat (20) which connects these panels (10) as a basic component. ing.

  As shown in FIG. 4, the photovoltaic power generation panel (10) includes a substrate (11), a photovoltaic cell module (12) laminated on the upper surface side of the substrate (11), and a laminated surface on the upper surface side of the photovoltaic cell module (12). And a transparent upper surface protective layer (13) and a lower surface adhesive layer (15) laminated on the lower surface side of the substrate (11).

  As for a board | substrate (11), the steel plate is comprised with metal plates, such as a stainless steel plate. In particular, steel plates are highly rigid, making them ideal as panel substrates, protecting the photovoltaic module (12) being held from stresses such as bending, and ensuring that the photovoltaic module (12) is not damaged. Can be prevented. Furthermore, the board | substrate (11) made from a steel plate is excellent also in adhesiveness with the below-mentioned lower surface adhesive layer (15), and can hold | maintain and fix an adhesive layer (15) reliably.

  In the present invention, the substrate (11) is not limited to the steel plate described above, and any substrate can be used as long as it is made of metal.

  When using a steel plate as a board | substrate (11), it is good to set the thickness to 0.4-1.2 mm. That is, if it is too thin, it will be difficult to ensure sufficient rigidity, and conversely if it is too thick, the overall weight of the panel may be increased, and workability may be reduced.

  Crystalline silicon is used for the photovoltaic module (12). As this silicon, either a single crystal type or a polycrystalline type can be used. In short, any silicon having a crystal structure can be used.

  Crystalline silicon has higher photoelectric conversion efficiency and higher power generation efficiency than, for example, amorphous silicon. For example, even when the panel construction area is small, a large amount of power generation can be secured.

  The upper surface protective layer (13) is used as a protective member for crystalline silicon as the photovoltaic module (12), and can protect the photovoltaic module (12) from external stresses such as impact, thereby improving durability. Can be made.

  As the upper surface protective layer (13), it is preferable to use a resin plate (sheet, film) in consideration of ease of construction by weight reduction and ease of end face processing (formability, workability, etc.), particularly weather resistance. From the viewpoint of transparency, it is more desirable to use a fluorine-based resin film such as an ethylene tetrafluoride ethylene copolymer (ETFE) resin film, a vinyl fluoride (PVF) resin film, or a vinylidene fluoride (PVDF) resin film. . In addition, a polyvinyl chloride (PVC) resin film, an acrylic film, a polycarbonate (PC) film, a polyethylene terephthalate (PET) film (including non-amorphous ones) and the like can also be employed.

  The resin film as the upper surface protective layer (13) has a thickness of 100 to 500 μm, preferably 150 to 300 μm. That is, when this thickness is used, it is possible to reliably improve the workability by reducing the weight while reliably protecting the protective characteristics.

  Further, as the upper surface protective layer (13), a hard layer may be used. That is, when a hard material is used, the surface is difficult to be scratched, clouding can be effectively prevented, and durability can be improved more reliably.

  As the hard upper surface protective layer (13), it is preferable to use, for example, a glass plate. That is, since the glass plate is excellent in impact resistance and scratch resistance, and has excellent chemical resistance with little chemical alteration, the above-mentioned protective properties can be improved.

  When a glass plate is used as the upper surface protective layer (13), a layer having a thickness of 2.0 mm or more is preferably used. That is, by adjusting to this thickness, sufficient strength can be obtained, and scratch resistance and the like can be further improved. In addition, when using a synthetic resin board as an upper surface protective layer (13) and providing hardness, it is good to set thickness to 0.5 mm or more.

  The lower surface adhesive layer (15) is for bonding and fixing the substrate (11), that is, the panel (10) to the connecting sheet (20) described in detail later, and is constituted by a thermoplastic synthetic resin film. . The adhesive layer (15) may be any resin as long as it is made of a resin that can be bonded to the connection sheet (20), but is compatible with the connection sheet (20), particularly the connection sheet. When using what consists of the same composition as (20), adhesive strength with a connection sheet (20) can fully be ensured, and attachment strength with a panel (10) can fully be ensured. . For example, when the connection sheet (20) is made of a polyvinyl chloride resin-based composition, the lower surface adhesive layer (15) is preferably composed of a polyvinyl chloride resin-based composition.

  In order to laminate and adhere the lower surface adhesive layer (15) to the substrate (11), a resin film as the adhesive layer (15) is fused and fixed to a metal plate such as a steel plate as the substrate (11) by a heat laminating method. Thus, the substrate (11) with the adhesive layer can be continuously produced by this thermal laminating method.

  In addition, you may make it form a lower surface adhesive layer (15) only in the part which joins a connection sheet | seat (20).

  In the present embodiment, a filling adhesive (14) as a sealant is used to laminate and integrate the substrate with adhesive layer (11), the photovoltaic module (12), and the surface protective layer (13). That is, with the substrate (11), the photovoltaic module (12), and the surface protective layer (13) laminated in this order, the photovoltaic module (12) is hermetically sealed between the substrate (11) and the surface protective layer (13). The adhesive (14) is filled in the mode to be sealed. Specifically, the adhesive (14) is applied to the upper surface of the substrate (11), and the adhesive (14) is applied to the lower surface of the surface protective layer (13) to protect the upper surface and the surface of the substrate (11). The photovoltaic module (12) is sandwiched between the lower surface of the layer (13), and in this state, is held under pressure until the adhesive (14) is cured. Thereby, a board | substrate with an adhesive layer (11), a photovoltaic cell module (12), and a surface protection layer (13) are connected and integrated in the lamination | stacking state, and a photovoltaic power generation panel (10) is produced.

  As the filling adhesive (14), an appropriate adhesive may be selected in consideration of adhesiveness to the substrate (11), the photovoltaic module (12), and the upper surface protective layer (13). An epoxy resin-based adhesive used as a material can be suitably used.

  On the other hand, as shown in FIG. 1 thru | or FIG. 3, a connection sheet | seat (20) is provided along the outer periphery part of the three photovoltaic power generation panels (10) arrange | positioned in parallel at predetermined intervals, and is a plane. It has a visual ladder shape. That is, the connecting sheet (20) is a belt-like both-side vertical sheet continuously arranged along the edge (both side edges) parallel to the panel arrangement direction (vertical direction) in the outer peripheral edge of the panel (10). A member (21) and a plurality of strip-shaped horizontal sheet members (22) arranged along an edge parallel to a direction (lateral direction) orthogonal to the vertical direction are provided.

  Of the horizontal sheet member (22), the horizontal sheet member (22) arranged along the adjacent panels overlaps and joins the opposite side edge back surfaces of the adjacent panel (10). Is done. Further, the lateral sheet members (22) at both ends have one side edge (inner edge) overlapped and joined to the back side of the outer edge of the panel (10) at both ends, and the other edge (outer edge). ) Are arranged so as to project outward in the vertical direction. In addition, the both side vertical sheet member (21) is joined with one side edge (inner edge) overlapping with the back side of both side edges of each panel (10) and the other side edge (outer edge). It is arranged so as to project outward in the lateral direction. Further, in the overlapping portion of the vertical sheet member (21) and the horizontal sheet member (22), the vertical sheet member (21) is overlapped and joined to the back side of the horizontal sheet member (22).

  The panel (10) and the sheet members (21) and (22) are joined by welding the sheet members (21) and (22) and the lower surface adhesive layer (15) on the back side of the panel with a solvent, hot air, and dielectric heating. In addition, they are joined and integrated by a fusing (welding) process by induction heating and an adhering process by an adhesive (hereinafter simply referred to as “welding process”). Furthermore, the joining between the sheet members (21) and (22) is to join and integrate the sheet members by a welding process.

  Thus, the three photovoltaic power generation panels (10) are connected by the connection sheet (20) to form the photovoltaic power generation panel set (1).

  In this panel set (1), the laterally projecting portions (21a) are formed by the portions projecting outward on both sides outwardly in the lateral direction from both side edges of the panels in the both side longitudinal sheet members (21), and the lateral sheets at both ends are formed. A vertically projecting portion (22a) is formed by a portion of the member (22) projecting outward in the longitudinal direction from both end edges of the panel. In other words, the outer peripheral portions (the overhang portions 21a and 22a) of the connection sheet (20) are arranged in a state of protruding outward from the installation area of the panel (10).

  In this panel set (1), as shown in FIG. 8, three panels (10) are alternately stacked by bending 180 ° with the horizontal sheet member (22) between adjacent panels as a hinge. It is configured to be foldable.

  Moreover, in the panel set (1) of this embodiment, as shown in FIG.1 and FIG.2, it is an electrode terminal in the intermediate position of the both-ends edge (front-and-rear edge) orthogonal to the vertical direction of each photovoltaic power generation panel (10). (16) is provided. Further, corresponding electrode terminals (16), (16) are connected by the cable (30) between the adjacent panels (10), and the outer electrode terminals (16), (16) of the panel (10) are connected to both ends at the both ends. One end of the cable (30) is connected for connection with another panel (10). For example, a flexible printed wiring board is used as the cable (30), and the board can be arranged along the connecting sheet (20) so that wiring can be performed with good fit.

  Here, the connection sheet (20) has waterproofness, and substantially the same waterproof sheet used for the sheet waterproofing method such as a building roof is adopted.

  Specifically, as the connection sheet (20), for example, thermoplastic synthetic resin such as polyvinyl chloride resin, rubber such as butyl rubber, ethylene propylene rubber (EPM), chlorosulfonated polyethylene, and thermoplastic elastomer such as olefin. What was shape | molded in the sheet form is employ | adopted, Especially, what consists of polyolefin-type elastomers, such as a polyvinyl chloride resin, a polyethylene resin, and a polyolefin-type resin, can be mentioned as a suitable example. As the connecting sheet (20), in addition to a single sheet made of a single synthetic resin, a composite sheet in which a plurality of synthetic resins are laminated, or a sheet having a reinforcing layer interposed therebetween can be used.

  The photovoltaic power generation panel set (1) having the above configuration is manufactured, for example, by the following procedure.

  First, as shown in FIG. 5, three photovoltaic power generation panels (10) are arranged in parallel at predetermined intervals in a state where the panels are turned upside down.

  Next, as shown in FIG. 6, the horizontal sheet member (22) is disposed from the back side of the panel along the opposing edges of the adjacent panels (10), and the horizontal direction in the panels (10) at both ends. It arrange | positions from a panel back surface side along the edge part, and a horizontal sheet | seat member (22) and a panel (10) are joined.

  In order to construct this panel set (1), first, as shown in FIG. 8, a plurality of disk-shaped sheet joining plates (52) are arranged at predetermined positions on the roof foundation (51) as a building frame. Each sheet joining plate (52) is fixed on the roof base (51) by penetrating a fixing tool such as a fixing nail through the joining plate (52) and driving it into the roof base (51).

  The roof substrate (1) is typically composed of concrete plates such as reinforced concrete (RC), lightweight foamed concrete (ALC), precast concrete (RC), but the material is not particularly limited. Absent.

  The sheet bonding plate (52) is formed of a resin-coated metal plate, for example, a resin-coated steel plate, in which at least one surface (upper surface) of the metal plate is coated with resin. As described above, the resin to be coated on the sheet bonding plate (52) is a resin composition having the same composition as the connection sheet (20) in consideration of compatibility (adhesiveness) with the connection sheet (20). It is preferable to comprise. For example, when the connection sheet (20) is composed of a polyvinyl chloride resin-based composition, the coating resin for the sheet joining plate (52) is preferably composed of a polyvinyl chloride resin-based composition.

  Next, it arrange | positions in a construction start position in the state which folded the photovoltaic power generation panel set (1).

Compared with the case of fixing, the installation work of the panel (10) can be performed efficiently.

  And in this embodiment, compared with the case where a photovoltaic power generation panel is fixed via a mount frame etc., the connection work between panels can also be performed easily. That is, as in the conventional example of FIG. 16 above, when the photovoltaic power generation panel (60) is fixed to the roof material via the gantry (65), in order to support the panel (60) on the gantry (65), It is necessary to fix the fixing frame (61) to the outer periphery of the panel (60), and it is difficult to provide electrode terminals on the outer peripheral edge of the panel (60). For this reason, generally, a terminal box (62) is provided on the back side of the panel (60), and the cable (63) is pulled out from the terminal box (62) on the back side of the existing panel and then installed. A method of pulling out the cable (63) from the terminal box (62) on the rear side of the newly installed panel to be connected and connecting the cables (63) (63) is adopted. Therefore, it is necessary to perform the wiring work by two persons, an operator who pulls out the cable (63) from the existing panel (60) and an operator who pulls out the cable (63) from the new panel (60). It will be troublesome and will cause a decrease in workability.

  On the other hand, in the panel set (1) of this embodiment, since the back surface side of a panel (10) is attached to a roof base | substrate (51) via a connection sheet | seat (20), the side end surface of a panel (10) The electrode terminal (16) can be provided on the terminal, and the connection work between the terminals (16) and (16) between adjacent panels can be easily and easily performed from the upper surface side of the panel, thereby improving the workability. Can do.

  Furthermore, in this embodiment, it is not necessary to form a terminal box on the back side of the panel, and accordingly, the overall structure can be reduced in size and slim, and the aesthetics can be improved.

  Moreover, in this embodiment, since the part corresponding to the corner | angular corner part of the photovoltaic power generation panel (10) in a connection sheet | seat (20) is joined and fixed to a sheet joining board (52), a photovoltaic power generation panel (10 ) Can be securely fixed to the roof base (51) via the sheet joining plate (52), and the photovoltaic power generation panel (10) can be attached in a stable state with sufficient strength.

  Moreover, since the photovoltaic power generation panel (10) of this embodiment uses crystalline silicon as the photovoltaic module (12), compared with the case where amorphous silicon is used, photoelectric conversion is efficiently performed. It can be performed and high power generation efficiency can be obtained.

  Moreover, since the photovoltaic power generation panel (10) in the panel set (1) of this embodiment forms a protective layer (13) on the surface, generation | occurrence | production of a damage and cloudiness can be prevented effectively, and durability Can be improved. Further, the surface protective layer (13) can prevent damage to the internal photovoltaic cell module (12) against collisions such as scattered objects, and can further improve durability.

  Furthermore, since the solar power generation panel (10) in this embodiment uses a highly rigid steel plate or the like as the substrate (11), bending deformation due to external stress or the like can be prevented, and damage to the photovoltaic module (12) can be prevented. It can prevent more reliably and can improve durability further.

  Moreover, since the panel set (1) of this embodiment can be folded using the connection sheet (20) between panels as a hinge, it can carry and store efficiently in the folded state.

  Further, since the panel set (1) in the folded state can be expanded and constructed, the panel set (1) can be easily aligned and thus laid, as in the conventional sheet waterproofing method.

  Moreover, in this embodiment, since a connection sheet | seat (20) is joined only to the outer periphery part of a panel (10), compared with the case where a connection sheet | seat is provided also in the back surface center of a panel, a connection sheet | seat (20). The amount used (total area) can be reduced, and the cost can be reduced by reducing the material cost. But in this invention, you may make it provide a connection sheet | seat (20) in the whole region including the panel back surface side from the outer periphery part of a panel (10).

  In addition, in this embodiment, although the connection sheet | seat (20) is not provided in the back surface side of the panel (20), since the part is watertight by the panel (20), a connection sheet | seat (20) and a panel ( 10), good waterproofness can be obtained over the entire construction surface.

  Moreover, in this embodiment, since a maintenance check can be performed separately with respect to a photovoltaic power generation panel (10), a connection sheet | seat (20), and a waterproof sheet (55), the maintenance check work is performed efficiently and smoothly. be able to.

  Furthermore, in the panel set (1) of this embodiment, since the clearance gap is formed between each photovoltaic power generation panel (10), each panel (10) and connection sheet | seat (20) are utilized by utilizing the clearance gap. ) Can be performed more efficiently.

  In addition, since this embodiment constructs using the panel set (1) which connected the photovoltaic power generation panel (10) with the connection sheet (20) previously, it is with a connection sheet (20) and a panel (10). The water tightness at the joint can be improved. In other words, if the solar power generation panel (10) and the connection sheet (20) are separated and applied, for example, as shown in FIG. 15, the vertical sheet member (21 of the connection sheet (20) is provided. ) Is laid on the roof base (51), and the horizontal sheet member (22) is further laid on the vertical sheet member (21), and then the photovoltaic power generation panel (10) is mounted on the connecting sheet (20). The construction method that joins to will be adopted. However, in the construction method, a gap (S) may be formed at the intersection of the vertical sheet member (21) and the horizontal sheet member (22) on the back side of the panel (10). This may make it difficult to achieve sufficient water tightness.

  On the other hand, in this embodiment, since a photovoltaic power generation panel (10) is joined beforehand to a connection sheet | seat (20), it can prevent reliably that a clearance gap (S) is formed. . That is, in the present embodiment, as described above, when the panel set (1) is manufactured, the horizontal sheet member is arranged in a state where the panel (10) is inverted and the back surface side is disposed on the upper side as shown in FIG. (22) and the vertical sheet member (21) are joined from the upper side. At the time of joining, the intersecting portions of the sheet members (21) and (22) are pressed from the upper side, thereby the sheet members (21) and (22). ) Can be joined to the panel (10) without a gap. Therefore, as shown in FIG. 3, even when the inverted state is returned to the normal state (the state at the time of construction), a gap is not formed, and sufficient water tightness can be reliably obtained.

  In the above-described embodiment, the case where three solar power generation panels are connected to form a panel set has been described as an example. However, the present invention is not limited thereto, and in the present invention, two or four solar power generation panels are provided. A panel set may be formed by connecting more than one sheet.

  Further, in the above embodiment, the case where the panels are arranged in the vertical direction and connected to form a panel set has been described as an example. However, the present invention is not limited thereto, and in the present invention, the panels are connected in the vertical direction and the horizontal direction. Thus, a panel set may be formed.

  Moreover, in the said embodiment, although the case where the photovoltaic power generation panel set was installed in the roof of a building was demonstrated, in this invention, the installation location of a panel is not specifically limited, For example, it installs in the side wall surface etc. of a building You may do it.

  Moreover, in the said embodiment, although a disk-shaped thing is used as a sheet joining board, this invention is not restricted only to it, For example, as shown in FIG. 13, a strip-like sheet joining board (53) is used. This is also possible. That is, a belt-like sheet joining plate (53) is fixed via a fixing tool along both sides of the laying region of the photovoltaic power generation panel set (1) on the roof base (51), and the panel is attached to the sheet joining plate (53). The connecting sheet (20) of the set (1) is fixed by a welding process. In this configuration as well, the same effect can be obtained as described above.
