Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure having a solar cell.

[0002]

2. Description of the Related Art Conventionally, it has been practiced to install a plurality of solar cells on the roof of a building structure such as a house and supply electric power to the house from the solar cells to save energy.

[0003]

By the way, the solar cell is
If you heat yourself excessively, energy conversion efficiency tends to decrease, so take measures to escape heat (heat dissipation),
A means for surely preventing a decrease in energy conversion efficiency is needed.

[0004]

The present invention has been made in order to achieve the above-mentioned object, and on the upper surface of the base panel stretched from the ridge side to the eaves side along the slope of the roof,
In a roof structure including solar cells in which solar cell panels are mounted side by side from the ridge side to the eaves side, a ventilation layer is formed between the base panel and the solar cell panel, and a ventilation layer and the outdoors are provided on the eaves side. It is characterized in that upper and lower eaves drainage plates that communicate with each other are provided, and a ventilation gallery is installed between these drainage plates.

[0005]

According to the present invention, the air flow through the ventilation layer through the ventilation gallery dissipates heat in the solar cell and suppresses the temperature rise, and the energy conversion efficiency of the solar cell is always kept high and a stable power supply is provided. Can be achieved. In addition, the ventilation louver makes it difficult for rainwater, dust, and the like to enter the ventilation layer, and also secures the intervals between the draining plates.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a schematic cross section of a roof structure of a house to which an embodiment of the present invention is applied, from a ridge M to an eaves N. Reference numeral 1 in FIG. 1 is a rectangular solar cell according to the present invention. The roof panel 1 is a roof panel 1 that forms a roof Y with its longitudinal direction extending from the ridge M to the eaves N.

The roof panel 1 with solar cells is constructed by arranging a plurality of solar cell panels 3 on a rectangular base panel 2. The plurality of solar cell panels 3 are
A panel in which a large number of solar cells 3a are arranged is supported by a lattice-shaped frame 4, and the frame 4 extends from the ridge M along the eaves N as shown in FIG. It is mounted and fixed on the support member 14 thus formed. The support member 14 forms a ventilation layer 5 between the eaves N and the ridge M between each solar cell panel 1 and the base panel. The ventilation layer 5 communicates with the ridge ventilation hardware 6 that constitutes the ridge M.

Here, in the eaves N, as shown in FIG. 2, a predetermined length is provided between the solar cell panel 3 closest to the eaves N side and the tip of the eaves N, and the entire length of the eaves N is there. An eaves plywood 7 is stretched over the frame 4, and an eaves drainer plate 8 on the upper side is further stretched over the plywood 7. In addition, a lower eaves draining plate 9 is stretched on the upper surface of the tip of the base panel 2 on the eaves N side. These draining plates 8 and 9 are bent further downward than the inclination of the roof Y at their tips, and their openings 10 face the inside of a gutter 11 provided at the eaves N. The opening 10 is closed by a ventilation gallery 12 having a large number of ventilation holes.

In the above roof structure, the wind blown outdoors flows into the ridge ventilation hardware 6 from the ventilation holes of the ventilation louver 12 provided at the eaves N, through the ventilation layer 5 of the roof panel 1,
From here it is discharged again outdoors. The flow of the wind (air) dissipates heat and suppresses the temperature rise of the solar cell panel 3, and as a result, the energy conversion efficiency of the solar cell is always kept high and stable power supply is achieved.
In addition, the ventilation louver 12 which is an intake port of air to the ventilation layer 5 prevents rainwater, dust and the like from entering the ventilation layer 5, and also serves as a spacer for ensuring a constant interval between the upper and lower eaves drainage plates 8 and 9. Perform a function.

[0011]

As described above, according to the roof structure provided with the solar cell of the present invention, the ventilation layer is formed between the base panel and the solar cell panel, and the ventilation layer is communicated with the outdoors at the eaves. The upper and lower eaves draining plates to be provided are provided, and a ventilation gallery is mounted between these draining plates.By the air flow through the ventilation layer through the ventilation gallery,
The heat dissipation of the solar cell is suppressed, the temperature rise is suppressed, the energy conversion efficiency of the solar cell is constantly maintained high, and a stable power supply can be achieved. This has the effect of ensuring the spacing between the plates.
