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. Recently, efforts to research and develop materials for module frames are becoming increasingly concrete in order to address the characteristics of the frame, which accounts for a significant portion of the weight within solar modules, and to reduce the cost of solar modules. In the case of steel module frames, they are generally made of two layers of ternary galvanized steel and a hemming method is applied at the point where the two layers meet, and as a result, the stiffness against torsional loads is very low.
