Description

The present invention relates to a roof structure in which a building material-integrated solar cell module is attached to a roofing board.

BACKGROUND ART A building material-integrated solar cell module that has a function as a building material (tile) in addition to a function as a solar cell has been known (for example, Patent Document 1).
Because this solar cell module is installed directly on a fixed structure such as a roof board without intervening roof tiles, it has an appearance that is integrated with other roof tiles, etc. It has a better design than battery modules.

JP2017-218866A

However, since solar cell modules that are integrated into building materials are directly fixed to roof boards, etc. without using roof tiles, if the solar cell panel ignites due to some kind of malfunction, the fire can spread from the solar cell module side to the fixed structure side. there is a possibility.
Furthermore, since a building material-integrated solar cell module is used as a building material (tile), it needs to be more rigid than a normal solar cell module that is fixed to a roof tile.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a roof structure that is safer than conventional roof structures and in which solar cell modules are less likely to deform. Another object of the present invention is to provide a solar cell module that is safer and less susceptible to deformation than conventional solar cell modules.

The solar cell module has two side wall portions bent and extending toward the solar cell panel, and the solar cell module includes a rear surface of the solar cell panel, the mounting wall portion, and an enclosure surrounded by the two side wall portions. The surrounding space is a roof structure that is open in the direction of the eaves.

The term "most part of the back surface of the solar panel" as used herein refers to 60% or more of the back surface.

According to this aspect, most of the back side of the solar panel is covered with a metal reinforcement, so even if the solar panel catches fire, the fire will be blocked by the reinforcement and the solar panel will be able to escape from the side. Fire does not easily spread to the roof board side. Moreover, according to this aspect, since most of the back surface of the solar cell panel is covered and reinforced by the metal reinforcing portion, the solar cell panel is difficult to deform.
According to this aspect, since the reinforcing portion also functions as a pedestal for tilting the solar cell panel at a predetermined angle, the installation area of the solar cell panel per unit area of the roof board can be reduced. In addition, a terraced roof with excellent design can be constructed.
According to this aspect, since the enclosed space is open toward the eaves, the enclosed space can function as a flow path through which rainwater and the like pass.
