Description

  The present invention reduces the load on the foundation and existing roof (existing housing) at the time of new construction, and reduces the cost by making the panel with a simple configuration, and lays the solar cell panel on the exterior surface easily and inexpensively. The present invention relates to a solar cell panel that can be used and an exterior structure using the same.

In recent years, the social importance of solar cell systems has been widely recognized. However, in order to actually introduce a solar cell system, for example, a method of integrating a solar cell panel into a roof material itself, and a roof surface A method of fixing a mounting member such as a support base and assembling a solar cell panel thereon is known.
The method of integrating a thin film silicon solar cell typified by amorphous silicon into the roof material itself does not have strength by itself, so it is integrated with the exterior material and constructed in the same manner as the exterior material. The technology to manufacture the material and the technology to manufacture the solar cell panel are necessary, and it is not suitable for any base, and it is necessary to make the base structure in accordance with it to lay the integrated exterior material As a result, it was expensive.
On the other hand, the method of assembling the solar cell panel by fixing the support frame to the roof surface is a structure in which the solar cell panel is installed on the existing roof by assembling the support frame in a frame shape. In many cases, the number of points increases, and it takes time and effort to manage the members, and the overall weight of the support frame and the solar cell panel is a heavy burden on the structure (frame or existing building).

  In recent years, solar cells have been developed that are lightweight and flexible modules like the thin film silicon solar cells described above, and that can be handled in the same way as a thick sheet or in the same way as a normal metal plate. However, since the amount of power generation has been increased, there is a demand for a device that can be easily applied (installed) to various existing roofs.

  Therefore, the present invention reduces the load on the base and the existing roof (existing housing) at the time of new installation, reduces the cost by making the panel with a simple configuration, and lays the solar cell panel on the exterior surface easily and inexpensively. For the purpose.

  The present invention has been proposed in view of the above, and includes a panel body provided with a solar energy conversion module in the face plate portion, and provided with a molding portion at least on the opposite side edge of the face plate portion, and attached to the molding portion of the panel body. A solar cell panel comprising a mounting member, wherein the molded part of the panel body has a folded part folded to the back side, and the mounting member includes a support part for supporting the molded part of the panel body; And a fixing portion to the base, and the back surface side of each facing molding portion of the panel body is supported by the supporting portion of the mounting member, and the molding portion is engaged with the mounting member and integrated. It is related with the solar cell panel characterized by these.

  Further, the present invention is characterized in that, in the solar cell panel, the face plate portion of the panel main body is supported from the back surface, and a reinforcing material having an upward convex receiving portion is disposed so as to straddle between the molding portions. We also propose a solar cell panel.

  Furthermore, the present invention also proposes an exterior structure using a solar cell panel, wherein the solar cell panel is laid so as to be convex upward with respect to the base surface.

The solar cell panel of the present invention has a structure in which a mounting member is integrated with a panel body provided with a solar energy conversion module in a face plate portion, and does not require a support frame as in the prior art and is also an integrated mounting member. It can be installed and installed very easily simply by fixing to the roof base, and can be installed on any base roof, such as a vertical surface.
Therefore, the solar cell panel of the present invention reduces the load on the foundation and the existing roof (existing housing) at the time of new installation, reduces the cost by making the panel with a simple configuration, and makes the solar cell panel inexpensive and simple. Can be laid on the exterior surface.

  Further, when the face plate portion of the panel main body is supported from the back surface and the reinforcing material having the support portion in an upward convex shape is disposed so as to straddle between the molding portions, it is desirable because the face plate portion can be maintained in a curved shape.

  Furthermore, in the exterior structure using the solar cell panel of the present invention, since the solar cell panel is laid so as to be convex upward with respect to the base surface, an exterior structure with high cross-sectional performance can be obtained. And it can apply easily irrespective of a new installation or the existing roof, and since it contributes greatly to introduction of a solar cell, the burden of the existing electric power company can be prevented.
