Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof having a solar cell module in which a tile material and a solar cell module are installed on a roof surface.

[0002]

2. Description of the Related Art In recent years, the number of houses in which a solar cell module is installed on a roof to obtain electric power by solar power generation is increasing. In this type of house, when installing the solar cell module on the roof, it is desirable in terms of appearance to give a sense of unity between the solar cell module and the tile material.

Therefore, a plurality of pedestals are attached to the roof surface along the roof inclination direction, and the eave-side end of the ridge-side solar cell module and the ridge-side end of the eave-side solar cell module are overlapped. There is a structure in which a large number of solar cell modules are installed on a gantry, similarly to the surrounding tile material.

[0004]

However, in the above structure, since the solar cell modules are arranged side by side in a rectangular space surrounded by a partition member or a decorative member mounted on the roof surface, the partition member or the solar cell module is not provided. The tile material and the solar cell module were separated by the decorative material, and it was not possible to install them with a sense of unity therebetween. For this reason, the whole roof lacked a sense of unity, and the appearance was worse.

As described above, the tile material and the solar cell module are installed in a state of being separated from each other because the tile material and the solar cell module are continuously connected in the roof inclination direction, the girder direction, or the beam direction without a sense of incompatibility. This is because the technology for installation has not been established.

In particular, it is difficult to effectively dispose the solar cell modules over a wide area when the solar cell modules are installed in a rectangular space with respect to a roof surface such as a triangular or trapezoidal roof. It is difficult to secure sufficient power generation. Moreover, for roofs such as triangles and trapezoids,
If the photovoltaic module is installed in a square shape, the appearance of the photovoltaic module becomes worse.

[0007] In view of the above, the present invention has been made to solve the above-mentioned disadvantages, and to continuously install a tile material and a solar cell module without separating them, and to effectively install a solar cell module according to the shape of a roof surface. It is an object of the present invention to provide a roof provided with a solar cell module that can improve design and power generation efficiency by being arranged.

[0008]

A tile in which the length of the roof inclining direction is set to 0.5 m to 0.7 m is a roof in which these are installed on an inclined roof surface. Tiles, one of which is located on the ridge side, is installed in a stepwise manner so that it is placed on the other ridge side end which is located on the eave side, and the tiles are adjacent in the girder direction or the beam direction. The material and the solar cell module are arranged side by side such that their upper surfaces are substantially flush.

Then, by shifting the ends of the rectangular solar cell modules adjacent to the roof tilt direction along the roof tilt direction from each other in the girder direction or the beam row direction, a plurality of solar cell modules are formed into a roof surface shape. They are arranged together. Specifically, a square roof solar cell module that is adjacent to the roof ridge on the corner ridge side and the corner ridge side end along the roof sloping direction is stepped along the corner ridge It is arranged so that it becomes.

As is apparent from the above description, according to the present invention, the length of the roof tile in the roof tilt direction is set to be substantially equal to the length of the solar cell module in the roof tilt direction. Since these tiles and the solar cell module are installed continuously without being separated, a sense of unity is provided between the tile and the solar cell module, and the entire roof has a unified feeling. The appearance can be improved, so that the design can be improved.

In addition, since the length of the roof material in the roof tilt direction is adjusted to match the length of the solar cell module in the roof tilt direction, the design of an existing solar cell module is changed. It can be used as it is without any modification, and the design change can be completed on the tile material side having a simple structure, and the cost can be reduced.

Further, the solar cell modules adjacent to each other in the roof inclination direction are shifted from each other in the girder direction or the beam direction.
Since the solar cell modules are arranged according to the shape of the roof surface, for example, the solar cell modules can be effectively arranged even on a roof surface such as a triangular or trapezoidal shape of a wing roof, further improving the appearance. It is possible to obtain good power generation while ensuring a sufficient light receiving area.

Furthermore, if several types of solar cell modules having different lengths in the row direction or the beam direction are used, a variety of arrangements can be made by appropriately combining these, and a roof surface having a complicated shape can be obtained. Therefore, the solar cell module can be effectively arranged according to the shape.
