Description

  The present invention relates to a snow stop structure for a solar battery panel that is installed on the roof of a building such as a house.

  Conventionally, a solar cell panel (also referred to as a PV panel) is known as one of means for obtaining electric energy. This PV panel is often installed in a place where it is easy to receive solar energy. For example, it is generally installed on the roof of a building such as a house or a building.

  When installing the PV panel on the roof, construction corresponding to each region is performed. For example, in a snowy area, in order to prevent snow accumulated on the PV panel from sliding off from the surface of the PV panel, it is common to install a snow stop fitting or the like on the PV panel. This is because if the snow accumulated on the surface of the PV panel slips, the snow that has fallen may collide with a pedestrian or a car, or the snow that has slipped may jump into the site of the neighboring house. As a specific example of a PV panel having a snow stopper, in a PV panel composed of a light receiving part (solar cell module) and a frame that supports the light receiving part, the snow stopper is directly attached to the frame of the PV panel. A snow stop structure to be attached has been proposed (see, for example, Patent Document 1).

JP-A-8-13725

  However, in the conventional snow stop structure for solar cell panels, since the snow stop fittings are provided on the PV panel itself installed on the roof surface, it is difficult to reduce the load applied to the PV panel due to snow accumulation. Therefore, a load is easily applied to the PV panel, which may cause a failure of the PV panel. In addition, it is difficult to say that the snow stopper itself is fixed stably.

  The present invention has been made in view of the above points, can reduce the load caused by snow on the solar cell panel, and the snow of the solar cell panel can be stably attached for a long period of time. The object is to provide a stop structure.

The snow stop structure of the solar battery panel according to the present invention includes a plurality of pedestals fixed to a roof base, and a roof material in which ridges and flat plate portions are alternately formed in a direction orthogonal to the roof eaves direction. The solar cell panel placed on the roof material, and a snow stop member, the roof material is laid on the roof base so as to cover the pedestal with the ridges, the snow stop member is The roof material is connected to the pedestal with a fixture, and the top portion of the snow stop member is provided so as to protrude upward from the top surface of the solar cell panel. It is characterized by being connected to the plurality of pedestals by a fixing tool with a gap interposed therebetween .

Moreover, it is preferable that the said solar cell panel is in contact with the said snow stop member.
Moreover, it is preferable that the said solar cell panel is spaced apart from the said snow stop member.
The snow stop member includes a snow stop main body, a support piece, and a fixed piece, and the support piece protrudes from one surface of the snow stop main body, and the fixed piece is provided on the snow stop main body. It is preferable that the lower end protrudes in a direction opposite to the support piece .

  According to the snow retaining structure for a solar cell panel of the present invention, the load caused by snow on the solar cell panel can be reduced, and the attachment state of the snow retaining member is also stable over a long period of time.

An example of embodiment of the snow stop structure of the solar cell panel of this invention is shown, (a) is the perspective view, (b) is aa sectional drawing in (a), Comprising: The eaves side of the solar cell panel (C) is a front view from the eaves side of the roof, and is an enlarged view near the snow stop member. It is a perspective view which shows an example of the snow stop member used for the snow stop structure of the solar cell panel of this invention. It is an enlarged view of a part of the cross section showing an example of an embodiment of a roof having a snow stop structure for a solar cell panel of the present invention. It is a one part enlarged view of the cross section of a roof same as the above. It is sectional drawing of the eaves part of a roof, showing an example of other embodiment same as the above. The construction example of the roof which has the snow stop structure of the solar cell panel of this invention is shown, (a) And (b) is the schematic explaining the construction middle.

  Hereinafter, modes for carrying out the present invention will be described.

  As shown in FIGS. 1 (a) to 1 (c), at least a plurality of pedestals 3, 3,... The solar cell panel 20 placed on the roof material 10 and the snow stop member 1 are provided.

  Fig.1 (a) has shown the perspective view which shows a part of roof formed with the snow stop structure of the solar cell panel of this invention, The direction of the block arrow in a figure is the eaves side of a roof The direction from the building toward the building is shown. In addition, the eaves direction of a roof shows the same direction as the inclination direction (water flow direction) of a roof. FIG. 1B is an aa cross-sectional view in FIG. 1A, and is an enlarged view of the vicinity of the eaves-side end portion of the solar cell panel 20. Moreover, FIG.1 (c) shows the front view from the eaves side of a roof. Hereinafter, the snow stop structure of the solar cell panel of the present invention will be described in detail with reference to the embodiment of FIG.

As the roof base 30, for example, a base material formed by laying a base plate on a main building material, or a base material composed of a pier, a waterproof sheet, a base plate, a rafter, or the like can be used. A waterproof sheet may be laid on the roof base 30 as necessary. The pedestal 3 is fixed on the roof base 30. Although the shape of the base 3 is not specifically limited, For example, it can form in cross-sectional substantially hat shape (refer FIG.1 (b) and FIG.1 (c)). The pedestal 3 formed in this way has a base part 3a formed in a substantially inverted U-shaped cross section or a substantially inverted U-shaped cross section, and a flat plate-like shape extending outward from both lower ends of the base part 3a. It has support parts 3b and 3b. The flat support portions 3b and 3b are placed on the roof base 30 so that the extending direction thereof is along the eaves direction, and the pedestal 3 is protruded upward so that the pedestal portion 3a protrudes upward. Has been placed. The pedestal 3a is preferably bent substantially vertically downward from the side edge of the top surface of the pedestal 3a to form a pair of reinforcing pieces 35. In this case, the rigidity of the pedestal 3 is improved because the rigidity is improved. Deformation can be prevented. The base 3 can be formed by, for example, bending a metal plate. Of course, the pedestal 3 may be a rectangular column such as a rectangular parallelepiped or a cube other than the above-described substantially hat-shaped cross section. However, it is preferable to use the pedestal 3 having a substantially hat-shaped cross section in that the attachment state to the roof base 30 is stable and the weight does not become too large.

  The pedestal 3 can be fixed to the roof base 30 with screws or screws. For example, in the case of the pedestal 3 having a substantially hat-shaped cross section as in the embodiment of FIG. 1, screws and screws are driven into the pair of support portions 3 b and 3 b, and the support portions 3 b and 3 b and the roof base 30 are attached. What is necessary is just to penetrate. Although not shown in FIG. 1, a plurality of pedestals 3 can be provided at predetermined intervals along the eaves ridge direction.

  The roofing material 10 is laid on the roof base 30, and as shown in FIG. 1A, the ridges 11 and the flat plate portions 12 are alternately repeated in a direction orthogonal to the eaves ridge direction of the roof. Is formed.

  The ridge portion 11 is formed so that the metal plate is bent and protrudes upward (in a direction opposite to the roof base 30). The protruding line part 11 should just be formed over the substantially full length of the metal roof material 10, for example. The side surface of the ridge 11 may be formed as an inclined surface. That is, the ridge portion 11 may be formed so as to be inclined downward from the top surface side end to the flat plate portion 12. Of course, you may form so that it may hang down to the flat plate part 12 from the top surface side end of the protruding item | line part 11. FIG. In addition, in this specification, the extending | stretching direction of the protruding item | line part 11 is called "the longitudinal direction of the roofing material 10," and the direction orthogonal to the said longitudinal direction in the surface of the roofing material 10 is "the metal roofing material 10's. Sometimes referred to as “lateral direction”. The vertical direction and the eaves building direction are the same direction.

  In the roof material 10, the plurality of ridge portions 11 are arranged substantially parallel to each other. Further, the flat plate portion 12 formed between the adjacent ridge portions 11, 11 is substantially flat and is formed over substantially the entire length of the roof material 10 in the vertical direction.

  As shown in FIG. 1, the roofing material 10 is laid so as to cover the pedestal 3 with the ridges 11. That is, as shown in FIG. 1 (c), the roofing material is so arranged that the back surface side of the top surface of the ridge portion 11 (the top surface of the ridge portion 11a) and the top surface of the base portion 3a overlap each other. 10 is laid. In addition, since it depends on the number of arrangements and arrangement intervals of the pedestals 3, the roof material 10 may have protruding ridges 11 that do not cover the pedestals 3.

  A plurality of the roofing materials 10 are usually laid on the roof base 30, and specifically, the roofing materials 10 are laid while overlapping a part of the adjacent roofing materials 10 one above the other. For example, the roofing materials 10 and 10 adjacent to each other in the direction orthogonal to the eaves building direction include the protruding strips 11 at the side end of one roofing material 10 and the protruding strips 11 at the side end of the other roofing material 10. They may be laid one above the other. When the adjacent roof materials 10 are laid on top of each other in this way, the roof material 10 is stably laid on the roof base 30, and high waterproofness can be secured. The roofing material 10 may be spread over substantially the entire surface of the roof base 30, or may be laid on only a part of the roof base 30 (for example, the central portion except for the vicinity of the peripheral edge). In short, the roof material 10 should just be laid in the area | region where the solar cell panel 20 is mounted at least. The roof material 10 can be fixed to the roof base 30 by using, for example, screws or screws.

  The roofing material 10 can be manufactured by, for example, a known roll forming machine, may be manufactured by a bender processing machine, and end processing may be performed by hemming bending or pressing. The vertical and horizontal dimensions of the roofing material 10 may be appropriately set according to the area of the roof base 30 and the like. For example, the vertical length can be 1000 to 2500 mm, and the horizontal direction can be 300 to 1100 mm.

  On the top surface of the roofing material 10 laid as described above, the solar cell panel 20 is placed so as to bridge the plurality of ridges 11. In this embodiment, the solar cell panel 20 is formed by connecting a plurality of panel units 2 having a substantially rectangular shape in plan view to each other in the eave building direction and the direction orthogonal thereto. In the present embodiment, the four panel units 2 are connected to each other in the eaves-ridge direction and the direction orthogonal thereto so as to form one solar cell panel 20. Of course, in the present invention, the number of panel units 2 to be connected is not limited to the present embodiment. The top surface of the solar cell panel 20 (also referred to as the panel top surface 20a) is formed as a substantially flat surface. Moreover, as each panel unit 2, what is comprised by the light-receiving part (solar cell module) of sunlight as well-known and the frame (reinforcing member) which covers this circumference | surroundings can be used. The frame constituting the panel unit 2 is formed in a box shape having no bottom surface because its peripheral edge is bent substantially vertically downward and falls. The panel unit 2 can be fixedly attached to the roofing material 10 by connecting the frame body and the roofing material 10 with a connecting member such as a screw, as described later (see FIG. 4). You may make it fix using the member 25. FIG.

  The snow stopper member 1 is provided fixed to the roof material 10. Here, the shape and the like of the snow stop member 1 will be described in detail.

FIG. 2 shows an example of the snow stop member 1 that can be used in the present invention.
The snow stop member 1 includes a substantially flat snow stop main body 1a and a substantially flat fixed piece 1b that protrudes in a direction perpendicular to the surface of the snow stop main body 1a from a position near the center of the lower end of the snow stop main body 1a. Are formed in a substantially L shape. A fixing hole 1e for driving a screw, a screw or the like is formed in the vicinity of the approximate center of the fixing piece 1b. The planar shape of the snow stopper main body 1a is not particularly limited, and may be formed in, for example, a substantially rectangular shape. In the following, the direction perpendicular to the surface of the fixed piece 1b is referred to as the “longitudinal direction of the snow stop member 1”.

  The snow stop member 1 may further be formed with a substantially flat support piece 1c. As shown in FIG. 2, the support piece 1 c is formed in a substantially flat plate shape, and protrudes in a direction opposite to the protruding direction of the fixed piece 1 b from the vicinity of the approximate center on one surface of the snow stopper main body 1 a. It is provided as follows. And the support piece 1c is provided so that the surface may be orthogonal to the surface of the fixed piece 1b. Further, the support piece 1c is formed over substantially the entire length in the vertical direction of the snow stopper main body 1a, and the planar shape of the support piece 1c is not particularly limited, but is trapezoidal as shown in FIG. Alternatively, the shape may be a rectangle or a triangle. In the case of a trapezoidal shape, the support piece 1c only needs to be formed so that the longer side of the pair of parallel sides of the trapezoid contacts the snow stopper main body 1a. In addition, as the snow stop member 1 used by this invention, it is not limited to the above forms, It may have another form, A commercially available snow stop metal fitting etc. May be used. Moreover, the snow stopper member 1 may be a piece-shaped (short-length) component as shown in FIG. 2, or may be a component in which the snow-preserving main body 1a is formed long in the lateral direction. .

  As shown to Fig.1 (a), the snow stopper member 1 is provided along the edge part (panel eaves front-end | tip part 21) of the eaves side of the solar cell panel 20, and the snow stopper main body 1a is provided. It is arranged so that the side of the side faces the eaves. The fixing piece 1b is disposed on the convex strip portion 11 of the roof material 10 so as to be opposed to the pedestal 3 via the roof material 10 on the lower side of the solar cell panel 20 (FIG. 1 (b). )reference). The snow stopper main body 1a is disposed so as to face the panel eaves tip 21 and is disposed so that the snow stopper main body 1a stands upright with respect to the roof surface. As shown in FIG. 1, the top part 1f of the snow stop member 1 protrudes above the panel top surface 20a. The snow stopper main body 1a and the panel eaves tip part 21 of the solar cell panel 20 may be in contact with each other, or the snow stopper main body 1a and the solar cell panel 20 may be separated. When separated, a sealing member or the like may be interposed between the snow stop main body 1a and the solar cell panel 20. On the other hand, the lower end side 1d of the support piece 1c is arranged along the extending direction of the ridge portion 11 on the ridge portion top surface 11a.

  The snow stop member 1 can be fixed to the roofing material 10 by a fixing tool 5 such as a screw or a screw. In the embodiment of FIG. 1, the fixing tool 5 is driven into the fixing hole 1e of the fixing piece 1b. Thus, the roof material 10 and the top surface of the base portion 3a of the pedestal 3 are penetrated, and are fixed to the roof material 10 so that the pedestal 3 and the snow stopper member 1 are connected.

  By providing the snow stop member 1 as described above, the surface of the snow stop main body 1a, the surface of the portion protruding above the panel top surface 20a, the snow accumulated on the solar cell panel 20 It will be possible to prevent slipping. In addition, the snow stopper member 1 is not fixed to the solar cell panel 20 but is fixed to the roof material 10 on which the solar cell panel 20 is placed. Even if it takes, the load concerning solar cell panel 20 itself can be reduced. Therefore, it becomes easy to prevent failure of the solar cell panel 20, and the installation state of the solar cell panel 20 can be stabilized over a long period of time.

  Furthermore, since the snow stopper member 1 is connected to the pedestal 3 fixed to the roof base 30 with the roof material 10 interposed, the attachment state of the snow stopper member 1 becomes more stable by such connection. . Therefore, even if a large load due to snow accumulation is applied to the snow stop member 1, it can withstand sufficiently and the snow stop structure is stable over a long period of time. Further, when the snow stop member 1 is provided with the support piece 1c as in the present embodiment, the snow stop body 1a is supported by the support piece 1c, so that the snow stop member 1 is more stable on the roof material 10. It becomes fixed to. In particular, in the snow stop member 1, when the distance from the fixed piece 1b which is a fixed portion to the top 1f of the snow stop main body is long, the bending moment becomes easier to work against the pressure due to snow accumulation, resulting in insufficient strength. However, the lack of strength can be compensated for by having the support piece 1c. Therefore, since the load of snow can be supported also by such a support piece 1c, the above effect can be further enhanced.

  It is preferable that the fixing tool 5 driven into the fixing piece 1b of the snow stop member 1 does not reach the roof base 30 at the tip, and in this case, the waterproofness can be further increased. If the tip of the fixture 5 reaches the roof base 30 and is driven into the roof base 30, rainwater or the like may enter the inside or inside of the roof base 30 through the fixture 5. This is because the infiltration of rainwater can be prevented by using the configuration.

  The protruding height H of the snow stop member top 1f may be designed to prevent the snow from sliding down and to minimize the influence of the power generation efficiency due to the shadow formed on the surface of the solar cell panel 20. Therefore, although the protrusion height H is not particularly limited, for example, if it is 20 to 50 mm, the falling snow on the solar cell panel 20 is sufficiently prevented. The protrusion height H is, as shown in FIG. 1B, the height from the surface of the roof base 30 to the top of the snow stop member 1f and the height from the surface of the roof base 30 to the panel top surface 20a. Indicates the difference.

  In the embodiment of FIG. 1, the snow stop member 1 is provided at only one location along the panel eaves tip 21, but is not limited thereto, and a predetermined interval is provided along the panel eaves tip 21. A plurality of them may be provided, or they may be provided adjacent to each other without any interval. Alternatively, the long snow stop member 1 described above may be used and provided over substantially the entire length of the panel eaves tip 21. In this case, the snow stop effect can be further enhanced.

  As shown in FIG. 3 and FIG. 1A, the snow stopper member 1 is not only the panel eaves tip 21 but also the snow stopper member 1 is interposed between the panel units 2 and 2 constituting the solar cell panel 20. It may be provided. FIG. 3 is a cross-sectional view taken along the line aa in FIG. 1 (a), and shows the vicinity of the snow stop member 1 provided between the panel units 2 and 2 adjacent in the eaves-ridge direction. It is an enlarged view.

  In this embodiment, the support piece 1c of the snow stop member 1 is interposed between the panel units 2 and 2 adjacent to each other in the direction orthogonal to the eave building direction, and the snow is between the panel units 2 and 2 adjacent in the eave building direction. The snow stop member 1 is disposed with the stop main body 1a interposed. Since the support piece 1c is interposed between the panel units 2 and 2, adverse effects such as a decrease in the number of installed solar cell panels 20 due to the provision of the snow stop main body 1a can be suppressed. The other configuration such as the arrangement and fixing of the snow stopper member 1 is the same as that of the snow stopper member 1 described above, and the description thereof will be omitted.

  As described above, by providing the snow stop member 1 between the panel units 2 and 2 adjacent in the eaves-ridge direction, the effect of snow stop can be further enhanced. Of course, it is also possible to provide the snow stop member 1 while leaving a predetermined interval (or adjoining each other without leaving an interval) over substantially the entire length between the panel units 2 and 2 adjacent in the eaves-ridge direction. In this case, the snow stopper member 1 having no support piece 1c may be used as the snow stopper member 1. That is, the snow stop member 1 having the support piece 1c is supported on the cross joint portion where the four panel units 2 are formed adjacent to each other, and is supported on the straight joint portion where the two panel units 2 are formed adjacent to each other. What is necessary is just to use the snow stop member 1 which does not have the piece 1c.

  Here, the other structure of the roof which has the snow stop structure of the solar cell panel of this invention is demonstrated.

  FIG. 4 shows a cut surface along the eaves direction of the roof, and shows an enlarged vicinity of a connection portion between the panel units 2 and 2. When installing the solar cell panel 20 as in this embodiment, the solar cell panel 20 can be connected to the pedestal 3 using the support member 25.

  The support member 25 has a substantially flat panel connection portion 25c and a substantially flat fixing portion 25b bent at a substantially right angle at the lower end of the panel connection portion 25c, and is formed in a substantially L shape. . On the other hand, at the upper end of the panel connecting portion 25c, a pair of engagement pieces 25a, 25a are formed in a substantially m-shaped cross section symmetrically in the left-right direction. The panel connection part 25c is arrange | positioned between the panel units 2 and 2, and the adhering part 25b is arrange | positioned and fixed on the roofing material 10 (projection strip part 11). Further, the engaging piece 25a is hooked and engaged with the engaged piece 2a that can be engaged with the engaging piece 25a formed on the frame of the panel unit 2, and the adjacent panel units 2 and 2 can be connected to each other. I have to. In addition, if the support member 25 is a piece shape, it can provide with two or more between adjacent panel units. The support member 25 may be formed in a long shape. The support member 25 is shown as an example, and of course, other shapes may be used. If the solar cell panel 2 and the roof material 10 are connected to each other, the shape is particularly good. Is not limited.

  A fixing tool 5 such as a screw or a screw is driven into the fixing portion 25b, and the fixing tool 5 covers the fixing portion 25b, the protruding strip portion 11 of the roof material 10, and the top surface of the base portion 3a of the base 3. It penetrates. By providing the fixture 5 in this way, the solar cell panel 20 is fixed to the roofing material 10 while being connected to the base 3.

  The support member 25 can be provided between the panel units 2 and 2 adjacent to each other in the eaves-ridge direction and at a place where the snow stop member 1 is not provided. Further, the snow stopper member 1 and the support member 25 may be provided in parallel between the panel units 2 and 2.

  If it is set as the connection structure using the base 3 as mentioned above, the distance between connection parts can be shortened compared with the case where the solar cell panel 20 and the roof base | substrate 30 are connected directly. For this reason, even if the solar cell panel 20 vibrates due to an external force such as a wind force or an earthquake, the vibration at the connection portion is less likely to be amplified than when the distance between the connection portions is long. As a result, the solar cell panel 20 Therefore, the positional deviation is less likely to occur, and the installation state is stabilized. Furthermore, since the pedestal 3 is firmly fixed to the roof base 30, it is difficult to give a large vibration to the solar cell panel 20. In addition, when installing the solar cell panel 20 on the roofing material 10, the fixture 5 may be driven toward the pedestal 3 immediately below, so that the possibility that the fixture 5 is obliquely inserted is reduced. Therefore, the solar cell panel 20 is more firmly fixed, and the connection is easily performed, so that the workability is excellent.

  Furthermore, since the pedestal 3 is provided on the lower side of the roofing material 10, the roofing material 10 is not easily bent or distorted even when a large weight such as the solar battery panel 20 is placed. Even if an external force is applied, vibration to the solar cell panel 20 is suppressed.

  Further, as in the case of the snow stop member 1, the fixing member 5 is preferably not inserted into the roof base 30, and in this case as well, the waterproofness is improved.

  FIG. 5 shows an example of an embodiment of the roof eaves structure, and the eaves may be waterproofed like this embodiment. FIG. 5 is a cross-section along the eaves direction of the roof, showing a cut surface passing through the snow stop member 1, and is an enlarged view of the vicinity of the eaves of the roof. As in this embodiment, a known eaves cover member 51 may be attached to the eaves. The eaves edge cover member 51 is connected and fixed to a cover support piece 53 fixed on the roof material 10 with a screw or the like, and a bent piece 51a at one end of the eaves edge cover member 51 abuts against the surface of the snow protection body 1a. Is provided. The cover support piece 53 may be connected to the pedestal 3 via the roof material 10 with screws or the like. Further, a well-known draining material 52 may be provided at the eaves of the roof base 30. The draining material 52 may be interposed between the roof base 30 and the support portion 3 b of the pedestal 3. In addition, about another structure, it is the same as that of the structure demonstrated in embodiment of FIG.

  In order to construct the roof having the snow stop structure of the solar cell panel of the present invention, for example, the following method can be used.

  FIG. 6A is a schematic diagram for explaining how the base 3 is attached and fixed to the roof base 30. First, the pedestals 3 are arranged and fixed at predetermined intervals in a direction perpendicular to the eaves direction, and further, the pedestals 3 are sequentially arranged and fixed at predetermined intervals from the respective pedestals 3 to the roof. The base 30 is constructed so that the bases 3 are arranged in a lattice pattern. The position for fixing the pedestal 3 should be determined in advance so that when the solar cell panel 20 is installed, the pedestal 3 is positioned below the solar cell panel 20 in consideration of the size of the solar cell panel 20 to be installed. . Further, when the base 3 is fixed, as shown in FIG. 6A, a fixing member 6 such as a screw may be driven into the pair of support portions 3b. In addition, the draining material 52 can also be attached as needed.

  Next, as shown in FIG. 6B, the roof material 10 is laid so as to cover the pedestal 3 with the ridges 11. In laying the roofing material 10, first, the roofing material 10 is laid at a predetermined position as described above, and then another roofing material 10 is prepared. The other roofing material 10 is laid so that the ridges 11 at the side ends of the roofing material 10 overlap each other vertically. In addition, in FIG.6 (b), although the protruding item | line part 11 in the most side end of one roofing material 10 and the protruding item | line part 11 in the most side end of the other roofing material 10 are piled up mutually, It is not limited to this. That is, by adjusting the overlapping dimension of the roof material 10, the plurality of ridge portions 11 of one roof material 10 may be laid so as to overlap the plurality of ridge portions 11 of the other roof material 10, respectively. Good. Further, in order to facilitate the overlapping of the roof materials 10 with each other, the width of the ridges 11 of the lower roof material 10 is shorter than the width of the ridges 11 of the upper roof material 10. It may be formed.

  Further, since the pedestal 3 shown in FIG. 6 (a) has the projection 3c formed on the top surface of the pedestal 3a, after the roofing material 10 is laid as described above, the roofing material 10 is attached to the roof base. When pressed to the 30 side, the shape of the protruding portion 3 c is transferred to the ridge 11. And since it becomes possible to visually recognize the installation position of the pedestal 3 on the lower side of the roofing material 10 using the transfer pattern of the protrusion 3c as a mark, the solar cell panel 20 and the snow stopper member 1 to be installed thereafter Positioning of the place to be arranged becomes easy.

  After laying the roofing material 10 as described above, the snow stopper 1 is attached and fixed on the roofing material 10. The snow stop member 1 may be attached to a predetermined position in consideration of the installation position and size of the solar cell panel 20 (panel unit 2), and as described above, the transfer pattern of the protrusion 3c of the base 3 Can be used as a landmark. In attaching the snow stopper member 1, the fixing tool 5 is driven into the fixing hole 1 e, and the roof material 10 and the top surface of the base portion 3 a of the base 3 are penetrated to connect the base 3 and the snow stopper member 1. Fix them while connecting. When the snow stop member 1 is provided not only at the panel eaves tip 21 but also at the cross joint (or straight joint) between the panel units 2 and 2, in parallel with the installation of the panel unit 2 on the eaves side. The snow stop member 1 may be attached.

  Moreover, when fixing the solar cell panel 20 using the supporting member 25 like the form of the above-mentioned FIG. 4, it can construct as follows.

  First, the snow stop member 1 and the support member 25 are disposed and fixed at a position where the front end (panel eaves tip portion 21) of the panel unit 2 is disposed. In attaching the support member 25, the fixing tool 5 is driven into the fixing portion 25b, and the convex portion 11 and the top surface of the base portion 3a are penetrated in this order. The attachment of the snow stop member 1 is the same as described above. Next, the panel unit 2 is arranged at a predetermined position. At this time, the engaging piece 25a (only one engaging piece 25a) of the support member 25 fixed in advance as described above is used as the frame of the panel unit 2.
