Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell tile structure in which a solar cell tile incorporating a solar cell that generates power when exposed to sunlight is attached to a wall surface of a building.

[0002]

2. Description of the Related Art It is common to all people that the best solution to global environmental problems is a solar cell that generates power when exposed to sunlight. However, the major drawback of the solar cell is that the energy density of sunlight is low,
The power generation efficiency of the solar cell is low, and a large installation area is required to generate a large amount of electric power.

On the other hand, there is an attempt to manufacture a large-area solar cell panel for use in electric power, but all of them have a structure in which the solar cell is fitted in a sturdy frame body, which increases the manufacturing cost. Weight has also increased and has not reached the mass production range.

Further, no specific proposal has been made yet to mount such a large number of solar cell panels.

[0005]

In view of the above problems, the present invention forms a large-area solar cell panel in the shape of a tile to be mounted on the wall surface of a building, and the solar cell tile can be simply and easily formed. It is intended to provide a solar cell tile structure which has high workability and can be mounted on a wall surface.

[0006]

According to the present invention, a solar cell tile main body having a solar cell provided on the back surface of a substrate made of a light-transmissive material such as glass is extended from the back surface side of its opposing end side. A mounting tongue is provided, the main body is fixed to the mounting rail juxtaposed on the surface of the building through the mounting tongue, and a fixing portion between the mounting tongue and the mounting rail is covered along the mounting rail. Covered with a cover.

[0007]

According to the present invention, the solar cell tile can be easily attached to the wall surface of the building with high workability.

Covered and protected.

FIG. 4 shows a cross-sectional view of another embodiment of the present invention. The tile body 1 has solar cells 3, 3, ... On the back surface of the light transmissive substrate 2 as in the case of FIG. The attachment tongues 4, 4, ... As in the case of FIG. 1 are not provided in this embodiment. Reference numerals 6 and 6 denote mounting rails having an H-shaped cross section which are horizontally mounted at predetermined intervals on the surface of a building having an inclined surface such as a house or an artificial dam, and are formed by extrusion molding a metal such as aluminum. ing. The depth of the H-shaped groove in each of the upper and lower directions is important. That is, the depth d of the H-shaped downward groove 7 is set to be larger than the depth D of the upward groove 8, and the vertical direction of the tile main body 1 inserted across the opposed grooves 7 and 8 is set. The length L in the direction is determined by the H-shaped mounting rails 6 facing each other,
It is set to be larger than the space K of the surface of 6 at least larger than the depth D of the upward groove 8.

By thus relating the depths d and D of the grooves 7 and 8, the vertical length L of the tile main body 1 and the surface distance K of the opposing rails 6 and 6, the tile main body 1 has a sliding door. Similar to the case of fitting, first the upper H-shaped rail 6-1
After the upper side of the tile main body 1 is fitted into the downward groove 7 of the solar cell tile main body, the lower side of the tile main body 1 is fitted into the upward groove 8 of the lower H-shaped rail 6-2. 1 is fixed to the opposing mounting rails 6,6.

FIG. 5 shows a structure in which the mounting structure shown in FIG. 4 is slightly modified. The difference from the case of FIG. 4 is that the mounting tongue similar to the structure of FIG. .. are provided, and the mounting tongues 4, 4, ... Are fitted and fixed in the upward grooves 8 and the downward grooves 7 of the mounting rails 6, 6 facing each other.

FIG. 6 is a modification of FIG. 5, in which notches 9 and 9 are provided in the downward groove 7 of the upper mounting rail 6-1.
The mounting tongues 4 and 4 provided upward from the tile main body 1 are fitted into the notches 9 and 9 (FIG. 6A), and then the tile main body 1 is shifted to the left or right (FIG. 6A).
B), the tile body 1 is fixed to the mounting rails 6, 6.

FIG. 7 shows still another embodiment of the structure of the present invention. In this embodiment, rails 10 and 10 having a U-shaped cross section are mounted upward on an inclined wall surface so that the lower side of the tile main body 1 is attached. After fitting in the upward groove of the lower rail 10-2, the upper side of the tile body 1 is brought into contact with the upper rail 10-1 and screwed 11.

FIG. 8 is a modification of the embodiment shown in FIG. 7, in which mounting tongues 4 and 4 are provided on the upper and lower sides of the tile main body 1, and the tile main body 1 is provided via the mounting tongues 4 and 4. Are fixed to the mounting rails 10 and 10. Incidentally, in the case of the embodiments shown in FIGS. 7 and 8, it is desirable from the standpoint of durability and the like that the 11 screw-fastening points are covered with a cover (not shown).

[0016]

According to the present invention, the solar cell tile can be mounted on the wall surface of the building with good workability and easily, and the mounting state is highly reliable, and the stable mounting state can be maintained for a long period of time. To be done.
