NOVELTY - The system has a mount frame (10) arranged in a horizontal installation surface. A cover body (20) covers a clearance gap from circumference of an inclined electric power generation module (P) to the installation surface. The electric power generation module is pressed by the installation surface with wind pressure, which blows against the electric power generation module. The mount frame is arranged by a foundation frame (11) arranged with the installation surface in parallel manner. A connection frame is supportably fixed to a front end of the electric power generation module.    USE - Mount frame system for installing a solar power generation module on a rooftop of a high-rise building. Can also be used for installing a solar power generation module on a ground.    ADVANTAGE - The cover body covers the clearance gap from the circumference of the electric power generation module to the installation surface, so that lift which suppresses inflow of wind entering into a bottom part of the mount frame and applied to the electric power generation module is reduced. The electric power generation module is pressed by the installation surface with wind pressure, which blows against the electric power generation module, so that the system is light in weight, electric power generation module installation is made to be stable with respect to strong wind and need of an anchor bolt and a block can be avoided. The system is provided with the foundation frame, so that the system can be installed in an easy manner. The system is provided with a blowing up prevention piece that prevents the electric power generation module from being blown up the mount frame, so that stability of the mount frame can be improved and possibility of detaching the mount frame from the installation surface can be performed effectively when the strong wind blows, thus simplifying structure of the mount frame making conveyance and assembly to be easy, and hence installing the electric power generation module on a rooftop of a high-rise building is performed in an easy manner. The mount frame is simultaneously mounted with the electric power generation module and the cover body simultaneous in pair with electric power generation module, so that width and shape of an installation position and arbitrary numbers of the electric power generation module can be installed conveniently. The electric power generation module can be installed without coating with water resistant protective layer, so that the electric power generation module is prevented from being damaged. The mount frame and the installation surface can be integrated together, so that high waterproof effect is achieved.    DETAILED DESCRIPTION - The cover body is made of synthetic resin material, metal material such as highly corrosion-resistant galvanized-steel-sheet material and carbonium steel material, iron material, aluminum material, stainless steel material or reinforced plastic material.
