Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof installation panel installed adjacent to a solar energy conversion panel on a roof.

[0002]

BACKGROUND ART Conventionally, there is a solar energy conversion device such as a solar cell or a solar heat collector that converts solar energy and uses it as electricity or hot water. In this device, a solar energy conversion panel having a solar energy conversion function is mounted on a roof. is set up. This solar energy conversion panel,
For example, a solar cell panel attaches a vertical frame and a horizontal frame to the periphery of a waterproof case containing a predetermined number of solar cells,
The vertical frame supports a rail-shaped support member fixed along the downward slope of the roof (see Japanese Patent Application Laid-Open No. H7-180310). The solar cell panel needs to radiate heat in order to prevent a decrease in power generation efficiency due to a rise in temperature, and the space between the solar cell panel and the roof base material is a ventilation layer for promoting heat radiation.

[0003] The solar cell panel is preferably arranged on the entire roof surface in order to increase the amount of power generation. Since the solar cell panel has a rectangular shape in a plane, it is used for a gable type roof having a rectangular roof surface. Installing a flat rectangular solar cell panel on a specially shaped roof with a sloped side where the roof surface forms an acute angle with the roof down direction, such as a ridge-type or gabled-roof type roof, is a triangle where panels cannot be installed This is not preferable in terms of the appearance of the roof because a dead space occurs.

Similarly, in a roof provided with a dormer, an inclined side is formed at an interface between the dormer and the roof at an acute angle to the downward direction of the roof, so that a triangular dead space in which a flat rectangular panel cannot be installed is formed. Installing a flat rectangular solar panel on this roof will result in
The appearance of the roof will be impaired. Therefore, conventionally, there is a roof structure in which a non-planar rectangular solar cell panel is disposed adjacent to a planar rectangular solar cell panel (see JP-A-7-90939).

[0005]

In the conventional example described in Japanese Patent Application Laid-Open No. 7-90939, although the roof is covered with flat rectangular and flat solar cell panels, there is an advantage that the amount of power generation is large, but the solar cell is advantageous. The installation cost of the roof is high due to the large number of panels to be installed and the preparation of a plurality of types of solar cell panels. In particular, because the flat-shaped solar panels are placed in a dead space with a relatively small installation area, their size is also reduced, and the types and number of solar panels are increased compared to the benefits obtained from power generation. There is a disadvantage that the accompanying disadvantages increase.

SUMMARY OF THE INVENTION An object of the present invention is to provide a solar power conversion panel on a specially shaped roof, such as a ridge roof, so that the entire surface of the roof is covered to improve the appearance and reduce the construction cost of the roof. It is to provide a panel for roof installation.

[0007]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to achieve the above-mentioned object by using a panel of irregular shape in a plane arranged adjacent to a solar energy conversion panel as a dummy panel. Specifically, the roof installation panel of the present invention will be described with reference to the accompanying drawings. As shown in FIG. A roof installation panel (5, 15) arranged adjacent to a planar rectangular solar energy conversion panel (4) having a function, the first edge (7) being joined to the solar energy conversion panel (4) and extending along the roof down direction; 19 and a second edge 9, 20 connected to the first edges 7 and 19 and corresponding to the inclined sides 1A and 1C, respectively, and the surface appearance thereof is the solar energy conversion panel. 4 is substantially the same as the surface appearance, and
It is a dummy panel having no solar energy conversion function.

In the present invention having this structure, the solar energy conversion panel 4 is arranged at the center of the roof, and the inclined side 1A of the roof is provided.
Roof installation panels 5, 15 are arranged in the vicinity, and these panels 4, 5, 15 cover the entire surface of the roof. When arranging the roof installation panels 5 and 15, the first edges 7 and 19 are aligned with the edge 7 of the adjacent solar energy conversion panel 4, and the second edges 9 and 20 are aligned with the inclined side 1A. This eliminates a dead space where the panels 4, 5, and 15 are not arranged on a specially-shaped roof such as a ridge, and improves the appearance. In addition, since the roof installation panels 5 and 15 are dummy panels, the production cost is much lower than that of the solar energy conversion panel, so that the roof construction cost can be reduced.

Here, in the present invention, the roof installation panels 5 and 15 are substantially triangular in plan, substantially trapezoidal in plan, and other shapes other than rectangular in plan. When the ventilation layer is formed between the roof and the roof, both side portions of the panel serve as support portions to the roof. However, if the roof installation panel is formed in a substantially trapezoidal plane, the support portion becomes longer, and the roof installation panel 5, 15 can be securely mounted. In addition, roof installation panels 5, 1
5 may be such that its bottom is attached to the roof base material 2 and its surface constitutes the roof surface. In this structure, the roof installation panels 5 and 15 themselves constitute the roof material, and the appearance of the roof is improved. On the contrary,
The roof installation panels 5 and 15 may have a structure in which the bottom is attached to a roof material that is installed in advance. In this structure, it can be retrofitted to the roof of an already constructed building together with solar energy conversion panels.
