DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile with a solar cell.

[0002]

2. Description of the Related Art Conventionally, various methods have been considered for installing a solar cell on a roof of a house or the like and utilizing electric energy of the solar cell by sunlight. For example, JP-A-5-243
It is known to install a panel-shaped solar cell unit on a roof, as described in Japanese Patent Application Publication No. 598 or the like. Also, Japanese Patent Application Laid-Open No. 57-68445 and
As described in Japanese Patent No. 28524, a tile with a solar cell on which a solar cell is mounted is known. In such a tile with a solar cell, the solar cell is bonded and fixed to the tile main body with an adhesive.

[0003]

However, as described in Japanese Unexamined Patent Publication No. 5-243598, the installation of a panel-shaped solar cell unit on a roof is performed by installing the solar cell unit on the roof. In this case, there is a disadvantage in that the process of waterproofing the seam with the surrounding roof requires a lot of man-hours, resulting in an increase in cost.

Also, as described in Japanese Patent Application Laid-Open No. 57-68445, a tile with a solar cell on which a solar cell is mounted can be laid in the same manner as a normal tile, so that a special waterproof treatment is required. However, since the solar cell is bonded and fixed to the tile main body with an adhesive, there is a disadvantage that the solar cell is easily detached from the tile main body due to a difference in expansion coefficient between the tile main body and the solar cell.

The present invention has been made in view of such a problem in a conventional tile with a solar cell and the like. It is an object of the present invention to solve the above-mentioned problem and to reduce the solar cell from the tile main body. An object of the present invention is to provide a roof tile with a solar cell which is not likely to come off.

[0006]

In order to achieve the above object, in the tile with solar cells according to the first aspect of the present invention, the solar cell is mounted in a concave portion provided substantially at the center of the tile body. A tile with a solar cell, wherein a flat part of a fixing member formed of a curved part or a bent part and a flat part is attached to a periphery of a concave part of a tile body, and a solar cell is formed by a tip of the curved part or the bent part of the fixing part. Are fixed to the roof tile body.

In the tile with a solar cell according to the second aspect of the present invention, the solar cell is mounted in a concave portion provided substantially at the center of the tile main body, and one end of a fixing bracket is attached to a periphery of the concave portion of the tile main body. A solar cell-attached tile in which the solar cell is locked to the tile body by the other end of the fixing member, wherein a cushioning material is interposed between the tile fixing member and the solar cell. is there.

According to a third aspect of the present invention, there is provided a tile with a solar cell, wherein the solar cell is mounted in a concave portion provided at a substantially central portion of the tile main body. An anchor insertion hole is provided around the concave portion provided in the portion, the fixing bracket is attached to the tile body via the anchor inserted in the anchor insertion hole, and the solar cell is fixed by the fixing metal. It is a feature.

In the present invention, the material of the tile body is
What has been conventionally used as a material of a tile can be used as it is, and is not particularly limited. For example, a sintered material such as clay, a hydraulic inorganic material such as cement and gypsum, a compressed slate Metals such as stainless steel, aluminum, and copper, synthetic resins such as FRP, polycarbonate, and acrylic resin, or composite materials in which such materials are appropriately combined can be used.

The solar cell may be a solar cell which has been conventionally used as a solar cell, and is not particularly limited. For example, the solar cell may be made of a silicon-based semiconductor or a compound-based semiconductor. Monocrystalline or polycrystalline crystalline semiconductors, amorphous semiconductors, etc. can be used, and the surface of these solar cells is, for example, surface protected with excellent transparency, such as ordinary glass or tempered glass, or an acrylic resin plate. The material may be coated.

[0011] The material of the fixing bracket is not particularly limited, but preferably has an appropriate elasticity enough to press the solar cell against the roof tile body and fix it. For example, a stainless steel plate, a galvanized steel plate, a vinyl chloride resin coating A steel plate, a surface-treated aluminum plate or the like can be suitably used, and the thickness thereof is preferably about 0.1 mm to 10 mm.

According to the first and second aspects of the present invention, as a means for attaching the fixing bracket around the concave portion of the tile body, a fixing hole may be formed by drilling a mounting hole at one end of the fixing bracket.
It may be bonded by an adhesive.

As the cushioning material according to the second aspect, it is desirable to use an elastic sheet having high water resistance, for example, butyl rubber, chloroprene acrylo rubber, ethylene propylene rubber, silicone rubber, fluorine rubber, and the like can be used.
The thickness is preferably about 0.1 to 5 mm.
If it is less than 1 mm, the cushioning effect may not be expected, and if it exceeds 5 mm, the function of fixing may be reduced.

According to the third aspect of the present invention, by providing the anchor insertion hole in advance at the time of forming the roof tile body, the number of steps can be reduced as compared with the case where the anchor insertion hole is later provided. In particular, when the roof tile body is made of an inorganic material, it is disadvantageous to form an anchor insertion hole with a drill or the like because of the number of working steps, the life of the drill, and the dimensional accuracy of the hole. Also, when the tile body is thin, drilling with a drill or the like, as described below, requires special skill so as not to penetrate the tile body,
It is more advantageous to provide an anchor insertion hole during molding.

It is preferable that the anchor insertion hole is provided so as not to penetrate the roof tile main body in order to ensure waterproofness. The depth of the anchor insertion hole is appropriately determined in consideration of the strength of the roof tile body and the mounting strength of the anchor.

A solar cell is inserted into the concave portion of the roof tile body in which the anchor is inserted into the anchor insertion hole, and a fixing bracket for fixing the solar cell can be mounted by screwing a screw or the like into the anchor position.

In the second and third aspects of the present invention, the fixing bracket is not particularly limited as long as it can fix the solar cell to the tile body, and may be, for example, a flat plate. As described in item 1, it may be composed of a curved portion or a bent portion and a flat plate portion.

[Function] In the roof tile with solar cells according to the first aspect of the present invention, the flat part of the fixing bracket formed by the curved part or the bent part and the flat part is attached to the periphery of the concave part of the tile body and fixed. Since the solar cell is fixed to the tile body by the tip of the curved or bent part of the metal fitting, the solar cell is pressed and fixed to the tile body by the elastic restoring force of the fixing metal, and the position is maintained. It can flexibly respond to changes in the shape of the main body over time and shocks such as earthquakes.

In the roof tile with a solar cell according to the second aspect of the present invention, since the cushioning material is interposed between the fixing bracket and the solar cell, an impact force is applied to the fixing bracket at the time of laying or the like. Even without damaging the solar cells.

According to the third aspect of the present invention, there is provided a roof tile with a solar cell, wherein an anchor insertion hole is provided around a concave portion provided substantially at the center of the roof body, and the anchor inserted into the anchor insertion hole. Since the fixing bracket is attached to the periphery of the tile main body through the, the fixing work of the solar cell to the tile main body is easy and there is no variation.
