Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof material for mounting solar cells.

[0001]

2. Description of the Related Art Conventionally, in order to mount a solar cell on a roof, a solar cell unit fixed to an aluminum frame is integrally installed on a roof with a general roof tile,
There has been a method in which a roof material (solar battery) having solar cells formed on the back surface of a glass substrate is directly nailed and fixed to a base plate.

[0002]

However, in the case where the above-mentioned solar cell unit is integrally installed, there is a possibility that rain leakage may occur due to the load and wind pressure of the unit and that the appearance of the building is impaired. The roof material with battery cells formed has the drawbacks that not only there is a risk of being stomped on by the worker during construction and the risk of the worker slipping, but also the subsequent maintenance (replacement work, etc.) is difficult. It was Furthermore, since it is thatched in the early stage of construction work, there is a drawback that the glass surface becomes dirty and the initial performance cannot be exhibited when spray-coating other parts in the subsequent process. An object of the present invention is to eliminate the above-mentioned conventional drawbacks.

[0003]

In order to achieve this object, the solar cell mounting roof material according to the present invention is characterized in that an engaging portion and an engaged portion capable of connecting vertically adjacent roof plate materials are provided. The roof plate member is formed at the upper end and the lower end, respectively, and a battery engaging portion that engages with the upper end of the solar cell is formed at the upper portion of the roof plate member, and the locking piece that receives the lower end of the solar cell is the roof plate member. Is provided with a connector portion that is detachable from the output terminal of the solar cell in the state of being locked with the lower end portion of the solar cell. In the above-mentioned configuration, it is preferable that an insertion hole is formed between the roof plate and the base plate in the vertically adjacent direction while the roof plate is attached to the base plate. Further, it is preferable that a sealing member for preventing rainwater from entering is provided at an engaging portion of the roof plate member that engages with an upper end portion of the solar cell.

[0004]

When the solar cell is attached to the roof, first, the roof plate material is roofed on the base plate, and the solar cell can be detachably attached to the roof plate material. In detail,
At the beginning of the construction work, the intrusion of rainwater is avoided by engaging the engaging and engaged parts of the roof plate with the engaging and engaged parts separately at the upper and lower ends with each other. In order to do so, the roofing boards that are adjacent to each other in the vertical direction are connected to each other and attached to the base plate. At the final stage after the processes such as spray painting, the solar cell is mounted on the roof plate by engaging the upper end of the solar cell with the battery engaging part formed on the upper part of the roof plate and connecting the terminals and the solar cell. The lower end of the roof plate is received by a locking piece that locks to the lower end of the roof plate material. With the above-mentioned configuration, with the roof plate material attached to the base plate, if an insertion hole in the vertically adjacent direction of the roof plate material is formed between the roof plate material and the base plate, ventilation is performed through the insertion hole. By doing so, the solar cell can be cooled and the power generation efficiency can be increased. Furthermore, by providing a sealing material that prevents the entry of rainwater into the engaging portion that engages with the upper end portion of the solar cell, rainwater may enter between the roof plate material and the solar cell to prevent leakage of electricity or corrosion of the solar cell. It can be prevented from occurring.

[0005]

According to the present invention, it is possible to mount a solar cell on a roof without causing rain leaks or spoiling the appearance of a building, and the solar cell mounting construction has been completed. Since it can be done later, it is possible to provide a roof material for solar cell installation that can greatly reduce the chances of operator's trampling damage and the risk of the operator slipping down, and the subsequent maintenance (replacement work, etc.) is extremely easy. It was

EXAMPLES Examples will be described below. As shown in FIG. 1 to FIG. 3, the roof material for mounting a solar cell includes an engaging portion 2 and an engaged portion 3 that can connect vertically adjacent metallic roof plate materials 1 to each other, and an upper end portion and a lower end portion thereof. Formed on the roof plate 1 separately, and a battery engaging portion 4 that engages with the upper end of the solar cell 5 is formed on the upper part of the roof plate 1 and a locking piece 6 that receives the lower end of the solar cell 5 is formed on the roof plate 1. The solar cell 5 is provided with a connector portion CN which is detachable from the output terminal P of the solar cell 5 in a locked state.

[0007] More specifically, the roof sheet material 1 is configured such that the upper end portion of a horizontally long rectangular sheet metal is bent upward to form a U-shape in cross section to form the engaging portions 2 and 4, and the lower end portion is on the lower surface side. The engaged portion 3 is formed by being bent inward. Similarly, the left and right ends of the sheet metal are bent to the lower surface side to form the engaging portions 7 and 8 for connecting the roof sheet materials 1 adjacent to each other on the left and right
The locking piece 10 is inserted and locked over the engaging portions 7 and 8. That is, the locking piece 10 has a function as a waterproof gutter. A connector CN for extracting the electrode of the solar cell 5 to the outside is provided at the rising portion 2A of the engaging portion 2, and an insertion hole H is formed at the falling portion 2B of the engaging portion 2 and further below it. The end face is bent as a mounting face to the base plate 9.

In the solar cell 5, a plurality of horizontally long solar cells 5B are similarly arranged vertically and horizontally on the back surface of a translucent horizontally long rectangular glass substrate 5A and bonded together with a filling adhesive. Connect the cells in series and put 2 in the upper center.
The book electrode 5C is attached so as to project.

A plurality of the roof plate materials 1 are attached to the left and right sides and attached to the lowermost end of the base plate 7, and a plurality of the roof plate materials 1 which are also engaged to the left and right sides are attached while engaging the upper side thereof. It has been roofed. The roof plate material 1

Prevents infiltration of rainwater between parts. The locking piece 6 is formed by bending a small-width plate-shaped member into a U-shape in cross section, and the bottom end is bent upward so that the bent portion 6A and the engaged portion 3 are locked. It is configured as follows. The locking piece 6 receives the lower end portion of the solar cell 5 in two lateral directions.

Another embodiment will be described below. In the above embodiment, the solar cell 5 is a crystalline silicon solar cell, but the type of solar cell is not limited to this, and may be, for example, an amorphous silicon solar cell formed directly on the glass substrate 5A. In the above embodiment, the locking piece 6 has been described as being configured to receive the lower end portion of the solar cell 5 at two locations in the lateral direction, but the number is not limited to two locations and is arbitrary. In the above-described embodiment, the lower end surface of the insertion hole H formed in the falling portion 2B of the engaging portion 2 is bent as a mounting surface to the base plate 9 and nailed and fixed to that portion. As shown in FIG. 4, the nailing may be directly fixed from above the engaging portion 2 that is bent and formed in a U-shape in cross section. In the above-mentioned embodiment, the description was given of the rising portion 2A of the engaging portion 2 provided with the connector CN for extracting the electrode of the solar cell 5 to the outside, but as shown in FIG. 5, the rising portion 2A and the falling portion 2A fall. It is formed so as to be separated from the portion 2B, and its falling portion 2B
