NOVELTY - The device has a module base formed in an upper portion of a mount frame (3). Several sheets of a solar cell module (5) are arranged in a module base (4) toward the top in a light-receiving surface (5a). A base packing (6) is inserted between the mount frame and a foundation (2), and the clearance gap is formed between the mount frame and foundation, while forming module base of mount frame using coppiced timber. The base packing is made smaller than mount frame. The step portion of undercut is formed on the bottom face of the mount frame and the side surface of base packing.    USE - Solar power generation device installed in rooftop, ground and seashore area.    ADVANTAGE - The mount frame is formed using the timber, so that the damage of mount frame by salt when the device is installed in the seashore area can be prevented, thus the prolonged use of the device can be achieved. The energy consumption and environmental load for manufacturing solar power generation device can be reduced. The base packing is inserted between the mount frame and foundation, and the clearance gap is formed between the mount frame and the foundation, so that the permeation of water content from foundation side to mount frame side can be prevented, thus the influence of solar cell module by rain water can be prevented, even if the mount frame is made of wood. The number of components used in the device can be reduced, thus the device can be installed easily. The module base can be used as the roof to prevent rain water and damping of mount frame. The module base can be used windbreak of the solar cell module with respect to the strong wind sprayed from the reverse direction, thus the swelling of solar cell module on the back side with respect to the strong wind sprayed from the light-receiving surface side can be prevented.
