Abstract: The present invention relates to a solar cell module and, more specifically, to a solar cell module in which solar cells are disposed to partially overlap each other so as to increase a space occupancy ratio of the solar cells and which is capable of solving safety and structural problems caused by the solar cells being disposed to overlap each other. In the solar cell module according to the present invention, the solar cells are disposed to partially overlap each other, thereby reducing a reactive power region and concurrently increasing a space occupancy ratio of the solar cells to increase power generation efficiency. In addition, a gap between portions at which the solar cells overlap each other is reduced to considerably reduce an incidence rate of cracks and damage, thereby improving stability and structural performance.
