Hence, intrusion of fire from the eaves front side or the roof face side to the solar battery panel can be prevented and the gas of the filler of the solar battery body 12 in the production process or in use can be removed because of the gap between the solar battery body 12 and the noncombustible member 19.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell roof structure and a solar cell panel, and can be used, for example, in a building such as a house.

[0002]

2. Description of the Related Art Conventionally, solar energy has been known as energy that does not adversely affect the environment and ecosystems. To utilize this solar energy, solar cells have been installed on roofs of houses and the like. I have. In installing a solar cell on a roof, a waterproof solar cell panel containing a solar cell, which is a solar cell, is used to prevent an accident such as electric leakage or short circuit due to water or the like. Such a solar cell panel is standardized in dimensions and the like so that a predetermined voltage and power can be obtained by one sheet, and a predetermined number of solar cells are arranged inside. The solar cell glass is disposed on the upper surface of the solar cell via an adhesive member such as EVA (ethylene vinyl acetate), which is a component of the solar cell panel.

[0003] Such a solar cell panel is attached to a roof surface with a gap formed between the solar cell panel and the roof surface. This gap communicates with the outside, and the air inside the gap can circulate with the outside air. Therefore, when the temperature of the solar cell panel becomes high, the solar cell panel is cooled by the air circulating in the gap, so that the power generation efficiency of the solar cell panel does not decrease.

[0004]

By the way, in the event of a fire in a house, a solar cell roof with a solar cell panel attached thereto is heated by EVA due to fire heat from the eaves or the roof surface.
May start burning. Then, while the EVA burns, it flows out of the gap between the solar cell panel and the roof surface and flows to the outside, and as a result, there is a possibility that the EVA may spread to a neighboring house. Therefore, there is a plan to make the solar cell panel nonflammable. As an example, it is conceivable to attach an incombustible material such as an iron plate to the lower surface of the solar cell.

However, in this case, there is an inconvenience if the non-combustible material comes into close contact with the solar cell. That is, gas is generated from EVA at the time of manufacturing a solar cell. If curing is performed for a period until the gas completely escapes and then the solar cell panel is manufactured, the manufacturing period becomes long, and there is a problem that an accurate manufacturing process cannot be formed. Even if it is installed after curing to some extent, gas may be generated during use of the solar cell panel, which is a problem.

SUMMARY OF THE INVENTION An object of the present invention is to provide a solar cell roof structure and a solar cell panel which can prevent fire from entering from the eaves side or the roof surface side and can release gas from the solar cell filler. is there.
