[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof tile with a solar cell, more specifically, a roof tile made of a translucent material, and the roof panel is provided with sufficient lighting for the solar cell on the back side thereof. The present invention relates to a technique that attempts to achieve inward lighting.

[0002]

2. Description of the Related Art Conventionally, a roof tile with a solar cell has a solar cell attached to the back surface of a flat roof tile made of a translucent material.

[0003]

However, in the case of such a structure, there is a problem that the solar cell attached to the back surface is sufficiently illuminated, but the indoor illumination is not sufficient. Moreover, since the conventional roof tile with a solar cell has a flat plate shape, it is difficult to enhance the appearance.

The present invention has been made in view of the above problems, and an object thereof is not only to illuminate the solar cell on the back surface but also to illuminate indoors and enhance the appearance. There is an attempt to provide roof tiles with solar cells.

[0005]

According to the present invention, the eaves side roof tile portion 1a arranged on the eaves side and the ridge side roof tile portion 1b arranged on the ridges side are formed in series with a step on the standing wall 1c. Along with
The eaves side roof tile portion 1a, the ridge side roof tile portion 1b, and the standing wall 1c are formed of a translucent material, and the eaves side roof tile portion 1a and the ridge side roof tile portion 1b are formed.
The solar cell 2 is attached to the back surface of the above.

[0006]

As described above, the eaves side roof tile portion 1a arranged on the eaves side and the ridge side roof tile portion 1b arranged on the ridges side are formed in series with the rising wall 1c at a step, and the roof side roof tiles are formed. The portion 1a, the ridge side roof tile portion 1b, and the standing wall 1c are formed of a translucent material,
The solar cell 2 is provided on the back surface of the eaves-side tile portion 1a and the ridge-side tile portion 1b.
By providing the solar cell 2 attached to the backsides of the eaves-side tile portion 1a and the ridge-side tile portion 1b, the solar cell 2 attached to the rear surface of the eaves-side tile portion 1a and the ridge-side tile portion 1b can be sufficiently erected. The wall 1c is adapted to illuminate indoors and to enhance the appearance at the step due to the standing wall 1c.

Embodiments of the present invention will be described in detail below with reference to the drawings. A long rail R having a groove 5 open laterally and on both sides is laid in parallel on a roof substrate 3 such as a rafter or a field board 4 laid on the main roof. The long rail R is laid in the eaves ridge direction. Although the cross-sectional shape of the long rail R is formed in a substantially E-shape, the shape and form thereof can be variously changed.
Thus, the facing grooves 5 on the parallel long rails R
Both ends of the roof tile material 1x are slidably inserted into the roof tile material 1x to be roofed.

A part of the roof tile material 1x is the roof tile 1 with a solar cell. Hereinafter, the configuration will be described in detail. That is, as shown in FIG. 1, the eaves side roof tile portion 1 arranged on the eaves side.
a and a ridge-side tile portion 1b arranged on the ridge side are formed in series with a step by a standing wall 1c, and in the embodiment, the ridge-side tile portion is further provided on the ridge-side tile portion 1b. 1b is formed in series through the upright wall 1c. The eaves side roof tile portion 1a and the ridge side roof tiles portion 1b, 1b are formed of a transparent material such as glass, and the standing walls 1c, 1c are also formed of a transparent material, and these are formed in series. It is formed as a stepped roof tile 1. And the solar cell 2 is attached to the back surface of the eaves side roof tile part 1a and the ridge side roof tiles part 1b, 1b.

As described above, the eaves side tile portion 1 arranged on the eaves side
a, the ridge-side roof tile portions 1b, 1b arranged on the ridge side are formed in series with the standing wall 1c at different steps, and the eaves-side roof tile portion 1a, the ridge-side roof tile portions 1b, 1b, and the standing wall 1c. Are made of a translucent material, and the eaves side roof tile portion 1a and the ridge side roof tile portion 1 are formed.
By attaching the solar cell 2 to the back surface of b, the roof tile portion 1
a and the ridge-side roof tiles 1b, 1b, while the solar cell 2 attached to the back surface of the solar cell 2 is sufficiently illuminated, the intermediate standing wall 1
In c and 1c, daylight is taken indoors, and the appearance is enhanced at the step due to the standing walls 1c and 1c.

When the roof tile 1 and the roof tile material 1x are inserted into the concave groove 5 of the long rail R which is opposed to the roof tile 1, and the roof tile material 1x is installed between the roof tile 1 and the roof tile material 1x, the roof tile 3 is provided between the roof tile 1 and the roof tile material 1x. A gap d corresponding to the thickness of the lower piece Ra of the long rail R is formed, and a ventilation path is formed in this gap d, so that the durability of the roof substrate 3 and the like can be improved. The long rail R is laid over the entire length in the eaves direction, but the long rail R may be a single piece or a divided piece.
Then, as shown in FIG. 3, the eaves end plate 7 is fixed to the eaves side end of the long rail R by a fixing screw 8, and the eaves end plate 7 has an eaves roof tile 9 having a substantially L-shaped cross section. The roof tile 1 and the roof tile material 1x that are fixed and are installed on the ridge side from this are prevented from coming out.

Roof tile materials 1x other than those provided with solar cells 2
Is formed in the shape of a flat roof tile, and a protrusion 1d is formed on the lower surface thereof as shown in FIG. 2 so that the overlapping margin of the roof roof tile 1 and the flat roof tile material 1x can be determined. The solar cell 2 can be used, for example, by providing a ridge ventilation fan in the ridge to drive it, or by opening and closing a solenoid valve of a solar water heater on the roof or driving a pump. It can be used for various things.

EFFECT OF THE INVENTION As described above, the present invention forms the eaves side roof tile portion disposed on the eaves side and the ridge side roof tiles portion disposed on the ridge side by forming a step with the standing wall, and The eaves side roof tiles, the ridges side roofs and the standing walls are made of a translucent material, and solar cells are attached to the backs of the eaves side roofs and the roof side roofs. The solar cells attached to the back side of the roof can be fully illuminated, while indoor lighting can be performed on the standing wall between the eaves side tile and the ridge side tiles, and the appearance can be enhanced at the step due to the standing wall. There is an advantage that you can.
