However, in Patent Document 1 and the like, it is easy to connect the cables of the exterior panels adjacent in the flow direction, but there is a problem that the connection can be made only at the end when connecting in the left-right direction. Therefore, the cable wiring work at the time of construction is troublesome, and the work is extremely troublesome when the panel itself is accidentally damaged or periodically replaced.
Accordingly, the present invention provides a solar energy conversion module-integrated exterior structure that does not cause a problem in the above-described conventional method (structure), that is, can easily connect a cable of a lateral exterior panel. Objective.

The present invention has been proposed in view of the above, and in an exterior structure in which a panel material integrally provided with a solar energy conversion module is connected in a flow direction and a left-right direction, a vertical support for supporting left and right side edges of the panel material. a supporting member, between the seat member to have a support portion for supporting the fixed portion and the drainage member to the underlying, holds the drain member that is disposed in the flow direction, a back side of the drainage member a plurality The present invention relates to a solar energy conversion module-integrated exterior structure, characterized in that a space for passing a cable is formed at an interval between receiving members disposed at locations .

Further, the present invention provides a solar energy characterized in that, in the exterior structure described above , a fixing tool is driven by receiving a raised portion provided on a drainage member on a raised support portion also serving as a connecting portion provided on a seat member. A conversion module integrated exterior structure is also proposed.

Since the solar energy conversion module integrated exterior structure of the present invention has formed a space for passing the cable on the back side of the drainage member arranged in the flow direction, the drainage member does not hinder the wiring of the cable, The cable of the solar energy conversion module of the panel material adjacent in the left-right direction can be easily connected.
Therefore, the cable wiring work at the time of construction is extremely easy, and when the panel material itself is accidentally damaged or periodically replaced, the work can be easily performed.

  In particular, in an exterior structure including an exterior structure including a solar cell module and a general exterior structure not including a solar energy conversion module, the joint portion can be accommodated without a special structure.

Further, on the back side of the drain member, the case of providing the fixing portion of the base, a seat member having a supporting portion for supporting the drainage member member arrangement on its upper side a plurality of locations, the seat member is passed through the cable In order to play the role of a spacer that forms a space for the cable, the cable can be passed through the arrangement interval of the receiving member.

In addition, when the raised portion provided on the drainage member is supported by the raised support portion that also serves as the connection portion provided on the seat member and the fixture is driven , the displacement of the drainage member in the flow direction is prevented. DOO Ri Na, since the ridge-like supporting portion are fitted on the back side of the raised portion, stably drain member is disposed.

It is a side view which shows the state where another Example of the exterior structure of this invention adjoins the exterior structure which is not equipped with a solar energy conversion module.

The panel material applied to the exterior structure of the present invention has a configuration in which a solar energy conversion module (hereinafter referred to as a solar cell) is integrally provided, for example, a solar cell on a face plate portion of a known metal vertical casing material. Even in the case where the two are integrated in a laminated shape, a side edge cap made of a resin molding material or the like is integrated with the periphery of the solar cell that is long in the flow direction as in the illustrated embodiment to be described later, and the periphery is made of a support material or the like. The frame material may be used to surround the frame material, and the configuration and shape thereof are not particularly limited.
As the solar cell, any one such as polycrystalline, single crystal, amorphous, etc. 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. For example, recently proposed amorphous silicon solar cells having flexibility are preferable because they are extremely thin and lightweight.
The exterior structure of the present invention has the above-mentioned configuration “connecting the panel material in the flow direction and the left-right direction”, and the specific connection method (connection structure) is not particularly limited. .

  Moreover, the drainage member applied to the exterior structure of this invention points out what is distribute | arranged to a flow direction. That is, the members arranged in the left-right direction are distinguished as “running water members”. As a drainage member arranged in the flow direction, a threading material continuous in the flow direction is generally used. However, if drainage can be drained without leaking, a plurality of standard materials are connected in the flow direction. There may be. In addition, the drainage member may be a simple bowl-shaped material, or a configuration that also serves as a vertical support material that holds the side edges of the panel material, that is, a configuration that uses a vertical support material that includes a drainage portion that is continuous in the flow direction. However, the structure which connects the drainage part of a some vertical support material to a flow direction may be sufficient, and the structure and shape in particular are not limited.

And the space for letting a cable pass is formed in the back surface side of the drainage member arranged in the flow direction. Specifically, for example, a receiving member that is a piece material is interposed on the back side of a drainage member (or drainage part) that is a threading material. The seat member is not particularly limited in its configuration and shape as long as it has a fixing portion to the base and a drainage member disposed on the upper side or a support portion that supports a member having the drainage portion. .
In this way, the receiving member only needs to have a height through which the cable passes when combined with the drainage member (or drainage part), but the roof material (exterior surface) to be covered does not include solar cells. When a roof panel is installed, the intrusion water into the drainage member (or drainage part) is smoothed by setting the height of the space to be equal to or higher than the height of the roof material or the roof panel located under the water. Can be discharged onto the lower roofing material or roof panel.

The seat member is desirably provided with a connecting portion for fixing a drainage member or a member having a drainage portion as in the reference examples of FIGS. 1 and 2 described later. In this case, the drainage member is displaced in the flow direction. Movement will be prevented.
