  However, in the structure of Patent Document 1, the water-side frame (32) and the water-side frame (33) are used. In the structure of Patent Document 2, the water-side frame (11) and the water-side frame (12) are used. Since the frame material has a complicated configuration, these frame materials are special, and an increase in cost is inevitable.

  Further, in the structure of Patent Document 3, the support frame 1 is not physically fixed in the structure of Patent Document 4 and the frame body 1 and the frame body 1 are not physically fixed. It is integrated by fixing the covers 11 and 3 that cover the lower end of the solar cell module, rainwater flowing down on the module is blocked, and dirt, dust, etc. contained in the rainwater easily accumulate. It was a thing. As a result, dirt adheres to the module surface, and the performance is lowered, and the water-stopping material in the frame part is easily deteriorated.

  Therefore, the present invention provides a solar cell module that can reliably and easily fix the underwater side end of the solar cell module integrally without causing an increase in cost due to the use of a special member (frame). The purpose is to propose the structure and installation method.

  The present invention has been proposed in view of the above, and rail materials having support portions on which a solar cell module on the water side and the water side can be placed are arranged at predetermined intervals, and solar cells are provided between the rail materials.

  The installation structure of the solar cell module of the present invention is such that the lower end of the solar cell module is integrally fixed by the rail material and the mounting member, and the rail material and the mounting member to be used are extremely simple. Since it is a simple member and does not require a special frame material as in the prior art (Patent Documents 1 and 2), the cost can be reduced. Moreover, since the cover material is not used as in the prior art (Patent Documents 3 and 4), the rainwater flowing down on the module is not dammed, and the soil, dust, etc. contained in the rainwater are not deposited and are negative. It is possible to reinforce the strength improvement during the pressure action and the displacement stop in the flow direction. Therefore, the module surface can be maintained beautifully, and performance degradation such as power generation efficiency is not caused. Moreover, since the solar cell module is integrated with the rail member by the mounting member, the solar cell module can be easily replaced by attaching and detaching the mounting member.

In the structure in which the battery module is laid, the solar cell module laid on the water side of the rail material is mounted on the rail material on the back surface of the water-side end, and the surface of the solar battery module is engaged with the rail material. The mounting members are arranged at regular intervals with respect to the longitudinal direction of the rail material, and are integrated by engaging with the rail material from above.

The solar cell module used in the present invention only needs to be a panel made of a silicon-based, compound-based, organic-based solar cell, etc., and subjected to water sealing and waterproofing treatment at the periphery (small edge) as the module. However, it is preferable that there is no projection such as a frame at least in the direction intersecting the flow direction so as not to block rainwater flowing down the surface of the solar cell module. In order to increase the amount of power generation, a double-sided light reception (power generation) type solar cell may be used. In this case, a reflector may be interposed below the solar cell module.
Of the edges in the flow direction, the back surface of the water-side end is placed on the water-side support of the rail material, and the surface of the water-side end is engaged with the rail material. And is integrated (fixed) in a sandwiched manner from above and below.

The rail material used in the present invention has a water-side support portion and a water-side support portion that support an edge in the flow direction of the solar cell module, and an engaged portion that engages a mounting member described later. However, the specific configuration and other configurations are not particularly limited, and may be any shape or configuration, and may be composed of a single member or a plurality of members. But you can.
For example, regarding the water-side support portion and the water-side support portion, in the illustrated embodiment described later, since the solar cell module is adjacent in the flow direction, the water-side support portion and the water-side support portion are Although the level was formed in the level | step difference equivalent to the thickness of a solar cell module, it does not specifically limit.

The rail material is desirably a long material having the same cross section in the length direction as in the illustrated embodiment described later. In this case, the solar cell module to be used can be appropriately shaped (cut) according to the length dimension in the carry direction, and any size solar cell module can be handled very easily.
Further, it is desirable that the rail member has a support piece that protrudes to the underwater side as in the illustrated embodiment described later, in addition to the support portion described above.
