Description

Photovoltaic Module The present invention relates to a solar cell module. A solar cell module may include a laminate containing a solar cell that converts light energy into electrical energy by the photoelectric effect, and a module frame that supports the laminate. Since the module frame accounts for a significant portion of the weight of a solar cell module, various methods are being proposed to reduce its weight. For example, lightweight materials such as aluminum can be used to reduce the weight of the module frame. Although modular frames made of aluminum are relatively lightweight, they face the problem of being difficult to manufacture in various shapes due to limitations associated with the aluminum forming process. Accordingly, there is a demand for methods to reduce the weight of existing steel frames. FIG. 1 is a perspective view of a solar cell module according to one embodiment of the present invention. FIG. 2 is an exploded perspective view of a part of a solar cell module according to one embodiment of the present invention. FIG. 3 is a cross-sectional view of a module frame according to a first embodiment of the present invention.
