- the present invention relates to a fixing device for fixing a solar cell module to an installation surface such as a roof, and a method for fixing a solar cell module using the fixing device.
- solar cells have been installed in various places such as public facilities and general households due to environmental concerns and policies. Since solar cells use sunlight, they are installed outdoors, such as on roofs and rooftops. In order to make effective use of the installable surface, multiple solar cell modules (also called solar cell panels) are placed side by side. A group of solar cell arrays is often formed.
- the solar cell module Since the solar cell module is installed on the installation surface such as the roof or roof of the house, it is necessary to firmly fix the solar cell module to the installation surface using a fixing device composed of a gantry or a cross member so as not to be blown away by wind and rain.
- the installation cost is important as well as the power generation efficiency of the solar cell module.
- This installation cost is influenced not only by the price of the solar cell module itself, but also by the construction time of an operator who installs the solar cell module on the installation surface.

- Two drain holes 237 are formed at the lower ends of the end covers 230 and 230a to drain the water that has flowed into the base 111 of the first mount 110.
- the fixing device 100 supports two opposing side portions (first side portion 26 and second side portion 27) of the solar cell module using the first mount 110 and the second mount 150. It is a structure to do. Since the other two side portions other than the first side portion 26 and the second side portion 27 of the solar cell module are not supported, the load performance of the solar cell module is the four side portions surrounding the solar cell module. It is inferior compared with the case where all support.
- the fixing device 100 of this embodiment may further include a support rail 240 (support member) that supports the lower surface of the solar cell module 20.
- the installation method of the support rail 240 is not limited thereto, and the support rail 240 may be directly arranged on the installation surface 10. Further, the first frame 110 and the second frame 150 may be arranged between the two first frames 110 or between the two first frames 110.
