2. Description of the Related Art In recent years, due to global environmental problems, great expectations have been placed on solar cells which are installed outdoors to generate photovoltaic power. As a familiar application, a concept has been proposed in which a solar cell is installed on the roof of a general house, and the power generated by the solar cell covers daytime power consumption.

[0003] On the other hand, most of the roofs of ordinary houses are made of Japanese houses and are made of Japanese tiles.
To install the solar cells, as shown in FIGS. . . Is hung on one roof, and the lower end corner of the solar cell unit 12 is pulled and fixed with wires 13 from below one inclined surface of the roof, and the solar cell unit 12 is fixed. Is pulled over the roof ridge 15 from the other inclined surface of the roof by the wires 14, 14.

[0004]

However, since the solar cell unit formed by connecting a large number of solar cell panels described above is formed in a flat plate shape, the solar cell unit is installed along a slope when installed on a roof. Can be provided,
In the vicinity of the building, there is a gap between the photovoltaic unit and the roof because the solar cell unit needs to climb over the building. If the top corner of the unit is fixed to the roof by pulling it over the ridge with wires, there is a problem that the tiles are damaged, the installation is unstable, and the solar cell unit slides down.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has a solar cell unit in which a large number of solar cell panels that generate electricity by receiving sunlight are connected. The connecting angle of at least one connecting portion of the solar cell panel can be freely set, and when this solar cell unit is installed on one inclined surface of the ridge roof of a Japanese house, at least one connecting portion of the solar cell panel is provided. At an angle along the roof ridge, pull the lower end of the solar cell unit with a wire from below one of the slopes of the roof, and fix the upper end of the solar cell unit over the ridge. It is pulled and fixed by wire from the other slope of the roof .

[0006]

According to the present invention, the solar cell unit can be stably installed on the roof of a Japanese house, and a large load is not applied to the wire for attaching the unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments according to the present invention will be described in detail with reference to the drawings. 1 and 2 are a perspective view and a side view showing a solar cell unit of the solar cell system according to the present invention. Reference numeral 1 denotes a solar cell panel that generates power when receiving sunlight, and is formed of single crystal, polycrystal, or amorphous silicon, and has a length of 985 mm, a width of 445 mm, and a thickness of 3
The solar cell panel 1 has a flat plate shape of about 5 mm, and is formed by connecting four sheets. Reference numerals 2, 2, 3, and 3 denote support frames, which support both ends of the solar cell panels 1, 1, 1, 1 by pressing them from the solar light receiving surface side of the solar cell panels 1, 1, 1, 1. Pressing piece 4 having a width of about 10 mm,
4, 4 and 4, and the supporting frames 2 and 2 are configured by connecting three solar cell panels 1, and the supporting frames 3 and 3 support one solar cell panel 1. It is. The supporting frames 2 and 3 corresponding to the side surfaces of the solar cell panels 1, 1, 1, 1 are provided with metal fittings 5, which are flat connecting parts. , 6 so that the screw holes can be set horizontally or vertically so that the connection angles of the support frames 2 and 3 can be freely set. The length is set shorter than the diameter of the screws 6,6. Thus, the solar cell panel 1,
The solar cell unit 7 is formed by integrating 1, 1 and 1 with the use of the frames 2 and 3 and the metal fittings 5 constituting the connecting portion.

In this solar cell unit 7, after assembling on the ground, it is hung on a roof. At the time of transportation, the screws 6, 6 attached to the metal fittings 5 are firmly fastened so that the metal fittings 5 are not loosened, so that they can be easily lifted. The suspended solar cell unit 7 is installed along one inclined surface of the roof of the ridge, and a screw hole in the metal fitting 5 which is a connecting portion of the support frames 2 and 3 near the ridge 15 so as to match the angle. The screws 6, 6 are loosened and moved left and right to adjust the angles of the support frames 2, 3.

After the solar cell unit 7 is placed on the roof in this way, as shown in FIG.
The lower end of the solar cell unit is pulled and fixed with a wire 8 from below one inclined surface of the roof, and the upper end of the solar cell unit 7 is
By pulling and fixing with the wire 9 from the other inclined surface of the roof in a state exceeding 5, it is possible to obtain a solar cell system along the roof ridge 15.

FIGS. 4, 5 and 6 show another embodiment of the solar cell system according to the present invention, in which the solar cell panel 1 of the solar cell unit 7 does not go over the ridge 15 and the slope of the roof is not inclined. At the upper two corners of the solar cell unit 7, there are provided ridge-over fittings 10 for passing over the roof ridge 15. The ridge crossing bracket 10 has an L-shape formed of two support rods at the corners of the solar cell unit 7 and is attached to the two support rods with screws, and a hole for attaching the wire 9 to the top of the L-shape. Provided, 27
Even if it is pulled and fixed from any direction of 0 °, it is hardly deformed. The lower end of the solar cell unit 7 provided with such a ridge crossing fitting 10 is pulled and fixed to the wire 8 from below one inclined surface of the roof, and the upper end of the solar cell unit 7 is attached with the wire 9 to the ridge crossing fitting 10. Thereby, the wire 9 is pulled and fixed from the other inclined surface of the roof. In this way, the solar cell unit 7 can be stably installed using the wire without damaging the roof tile, and a stable solar cell system can be obtained on the slope of the roof.

[0011]

According to the present invention, it is possible to freely set the connection angle of at least one connection portion of the solar cell panels constituting the solar cell unit, and to install this solar cell unit on the roof of a Japanese house. When installing on one slope, fix the angle of at least one connection part of the solar cell panel at an angle along the roof ridge, and wire the lower end of the solar cell unit from below one slope of the roof. In addition, the solar cell unit is pulled and fixed with wires from the other slope of the roof with the upper end of the solar cell unit over the ridge, so the solar cell unit is stably installed on the sloped roof of a Japanese house Can prevent damage due to wind pressure, and does not place a heavy burden on the wires that attach the unit, and there is no risk of damaging the roof tiles.
