The Building-Integrated Photovoltaics (hereinafter, BIPV) system is a building-integrated photovoltaic power generation system, in which photovoltaic modules form the outer shell of a building, such as walls, windows, and roofs, to produce electricity in an eco-friendly manner. In particular, the exterior wall type BIPV system, in which the BIPV system is applied to the exterior wall of a building, can replace expensive building exterior materials, thereby securing economic feasibility.

Conventionally, an exterior wall type BIPV system was formed using a curtain wall method. In general, it is preferable to form an order wall for the outer wall of a building for thermal insulation. However, the conventional curtain wall method has a problem in that it is difficult to form an order wall due to spatial characteristics.

Accordingly, recently, a method of attaching a photovoltaic module to an outer wall using a piece is used. Patent Document 1 discloses a method of installing a Z-bar on an exterior wall and fixing a solar module to a module pedestal installed on the Z-bar as an external wall building-integrated photovoltaic power generation device.

However, in the method using a piece as described above, when an earthquake occurs, the joint between the piece and other adjacent pieces is damaged, and there is no configuration to bind the plurality of photovoltaic modules disposed adjacent to each other. There is a problem that the solar module can be easily damaged. In addition, there is a problem in that it is difficult to shorten the construction period and the construction process is increased because a skilled worker must construct it meticulously in order to prevent separation and separation of the photovoltaic module.
