The pedestal type solar panel is a structure in which a support pedestal is assembled in a frame shape on an existing roof, and the panel itself does not require rain performance as a roof (not considered) ) And rain is dependent on the existing roof.
The roof type solar cell panel has a saddle-like member that allows rainwater to flow down on the base (base plate, steel frame) together with the crosspieces (vertical crosspieces, horizontal crosspieces) or as an integrated crosspiece. In this structure, a solar cell panel is installed on a crosspiece, and the rain is achieved by connecting hook-shaped members.

The gantry-type solar cell panel has an advantage that it can be applied to various roof surfaces, but on the other hand, since it is installed on the roof, it basically requires a roof and has a problem in design. Compared with this, since the solar cell panel of the said roof material type | mold itself comprises a roof surface, it is excellent in the designability.
The structure proposed in Patent Document 1 is an example of the solar cell panel of the roof material type, and a configuration in which a collar portion is formed on a rail-like support member is disclosed.

As described above, the solar energy conversion module surrounds its periphery with a frame material, and various types of seal materials may be integrated around the periphery and held by the frame material via the seal material. The configuration and shape are not limited.
As this solar energy conversion module, any solar cell such as polycrystal, single crystal, and amorphous may be used. Generally, a solar cell is composed of a conductive substrate, a back surface reflection layer, a semiconductor layer as a photoelectric conversion member, and a transparent conductive layer. Examples of the conductive substrate include steel plates, copper, titanium, aluminum, stainless steel, and carbon sheets. In addition, a resin film such as polyester, polyimide, polyethylene naphthalide, and epoxy provided with a conductive layer, ceramics, and the like can also be used. The semiconductor layer is not particularly limited, and a compound semiconductor such as an amorphous silicon semiconductor, a polycrystalline silicon semiconductor, a crystalline silicon semiconductor, or copper indium selenide can be used.

A vertical inner collar 23B and a vertical outer collar 24B are provided.
And the inner rods of the frame material 2A arranged on the water side and the frame material 2B arranged on the one side (= the horizontal inner rod 23A and the vertical inner rod 23B), the outer rods (= the horizontal outer rod 24A and the vertical outer rod)樋 24B) is connected in an inverted L shape.
In addition, in drawing, the edge of the solar cell 10 was shown with the dashed-two dotted line.

The holding portion 21 of the illustrated embodiment is formed in a substantially U shape in each of the frame materials 2A to 2D, and the vertical piece portion 22 is formed in a vertical plane shape.
Further, the inner collar 23 (horizontal inner collar 23A, vertical inner collar 23B) is formed from a substantially horizontal bottom surface and a vertical planar side surface extending inward from the vertical piece portion 22 in the frame materials 2A and 2B, The outer casing 24 (the lateral outer casing 24A and the vertical outer casing 24B) is formed from a substantially horizontal bottom surface and a vertical side surface extending outward from the vertical piece portion 22, respectively.

Further, the frame material 2A disposed on the water side is provided with an engagement receiving portion 25 directed to the water side above the holding portion 21, and the frame piece 2D disposed on the water side has a vertical piece 22. An engaging portion 26 directed toward the water side is provided at the lower end of the head.
Since the engagement receiving portion 25 and the engagement portion 26 are provided as described above, the engagement portion 26 can be engaged with the engagement receiving portion 25 in the laid state as shown in FIG. When connecting in the flow direction, the positioning is properly performed, and it can be temporarily fixed at an appropriate position when fixing the screw, and rainwater and dew condensation water can be reliably guided to the lower solar cell panel 1.

  As shown in FIG. 2, the solar cell panel 1 of the present invention having such a configuration can be easily connected in a columnar shape in the flow direction and in a parallel shape in the direction of travel. , 1 can be led to the reverse L-shaped outer casing 24 (horizontal outer casing 24A, vertical outer casing 24B) along the outer side of the vertical piece 22 and the solar panel 1 Condensed water generated on the back side of the inner wall can be guided to an inverted L-shaped inner rod 23 (horizontal inner rod 23A, vertical inner rod 23B) along the inner side of the vertical piece portion 22, There is no need for a roof as in the case of a solar cell panel, and there is no need to install a separate hook-like member as in the case of a conventional roof material type solar cell panel. It is something that can be done.

Moreover, about each frame material 2A-2D, it prepares as an extrusion type material of the cross-sectional shape as shown in figure, respectively, and each length should just be determined according to the dimension (length and width) of the solar cell 10 to be used, The solar cell panel 1 can be easily formed for any size solar cell 10.
In addition, about attachment (fixation of a corner part) of each frame material 2A-2D, it does not specifically limit, Although it is common to attach with a screw stop etc., you may make it fix by welding etc. Good. Moreover, since the operation | work which attaches each frame material 2A-2D to the periphery of the solar cell 10 and forms the solar cell panel 1 does not need to be performed on-site, and can be implemented in a factory, the operation on-site is performed. It can be minimized. For this reason, it is possible to minimize the noise and other problems that occur in the vicinity of the site.

  Further, in the solar cell panel 1 of the present invention, rainwater entering from the gap between the solar cell panels 1 and 1 travels outside the vertical piece 22 and has an inverted L-shaped outer casing 24 (horizontal outer casing 24A, vertical outer casing 24A). Condensed water that is guided to the outer casing 24B) and is generated on the back side of the solar cell panel 1 travels along the inner side of the vertical piece 22 and has an inverted L-shaped inner casing 23 (horizontal inner casing 23A, vertical inner casing 23B). As is apparent from the side sectional view shown in FIG. 2 (b), these rainwater and dew condensation water have a drainage structure that is connected to lead to the outer casing 24 of the solar cell panel 1 adjacent to the lower stage. Explain what can be built.

  In the illustrated embodiment, the underwater side of the longitudinal inner collar 23B and the longitudinal outer collar 24B formed on the frame material 2B on one side is cut out (= the dimension is shortened) and the edge of the lower solar panel 1 is formed. Since it is arranged above the outer casing 24, the dew condensation water flowing through the vertical inner casing 23B and the rainwater flowing through the vertical outer casing 24B are reliably guided to the outer casing 24 of the lower solar panel 1.

  In this drainage structure, rainwater entering from the gap between the solar cell panels 1 and 1 and dew condensation water generated on the back side of the solar cell panel 1 are drained in separate flow paths, and the conventional roofing material It is not necessary to arrange a separate bowl-like member like a solar cell panel of the type, and it is very easy to construct with only the solar cell panel 1 and does not require various sealing materials, and fulfills rain. Can do.

Furthermore, as shown in FIG. 2C, the solar cell panel 1 of the present invention has a frame material on the other side in the outer casing 24 (vertical outer casing 24B) of the one side frame member 2B at the connecting portion in the left-right direction. The cable 101 is connected in a state where the lower end of the 2C vertical piece portion 22 is located, and extends from the terminal box 102 disposed on the back side of the solar cell panel 1 above the outer casing 24 (vertical outer casing 24B). It is possible to construct a wiring structure in which are connected (linked) vertically and horizontally.
In addition, at the lower end of the vertical piece portion 22 of the frame material 2C on the other side in the illustrated embodiment, a standing portion 221 bent in a substantially horizontal shape is provided on the inner side so as to be stably supported.

In the illustrated embodiment, an attachment portion 27 of the drainage cover 3 is provided at the upper ends of the frame material 2B on one side and the frame material 2C on the other side, and rainwater flows in the flow direction on the upper surface of the drainage cover 3 attached to the attachment portion 27. It was made to flow down.
As long as the drainage cover 3 is attached to the attachment portions 27, 27 formed at the upper ends of the frame members 2B, 2C, the specific configuration, shape, and material are not limited in any way. Thus, the left and right side edges may be bent upward, or may be a simple plate having a certain thickness, and may be made of metal, resin, or elastic rubber.

In this wiring structure, the lower end (standing portion 221) of the vertical piece portion 22 of the frame material 2C on the other side is in the outer flange 24 (vertical outer rod 24B) of the frame material 2B on one side at the connecting portion in the left-right direction. Since the cable 101 of the solar cell panel 1 is connected in the outer casing 24B, the wiring work can be performed near the surface, especially in the case of maintenance or replacement at the time of breakage. Thus, since it is not always necessary to remove the solar cell panel and perform the work as in the case of wiring on the back side, the work can be carried out very easily. As described above, the cables 101 are connected to each other in the flow direction, so that the cable 101 is led from the lower end of the vertical piece portion 22 of the frame material 2B into the lower outer casing 24B, and the lower solar panel. 1 is connected to the cable 101 of the lower solar cell panel 1 by extending the inside of the vertical outer casing 24B.
As described above, in the illustrated embodiment, the cables 101 of the solar cell panels 1 adjacent to each other in the flow direction are connected in the lower vertical casing 24B, and the wiring structure is formed in series in the flow direction (vertical direction). However, the present invention is not limited to this, and the cables 101 of the solar cell panels 1 adjacent in the direction of the girder are connected in the lateral outer casing 24A on the lower side, and the wiring structure is connected in series in the direction of girder (lateral direction). May be formed, or may be connected vertically and horizontally as appropriate.

  In the illustrated embodiment, since the drainage cover 3 is arranged as described above, it is possible to prevent a large amount of rainwater from flowing in when there is a large amount of precipitation such as heavy rain. It is possible to prevent the connected cable 101 from being immersed in rainwater.

In addition, the solar cell panel 1 of the present invention may be connected to be close to each other as shown in FIG.
FIG. 3 shows an example in which the frame material 2B on one side of the left and right sides and the frame material 2C on the other side are close to each other, and the mounting portion 27 and the drainage cover 3 are not provided. Thus, it can also be said that the connection part of the panel adjacent to right and left in the state which does not need to connect the cable 101. FIG.
However, in the case of connecting the solar cell panels 1 to the left and right, it is common that a predetermined work interval is required and an operator inserts a hand or a jig into the interval to perform the connection work. Connection work cannot be performed in close proximity.
Therefore, this FIG. 3 can also be said to be a mode in which the space between the left and right frame members 2B and 2C is not used as a connection space for the cable 101.
