NOVELTY - The mount frame (2) is provided with an electric power generation panel and a frame segment that is provided in a circumference of an electric power generation panel which produces electric power by light receiving sunlight, and supports the electric power generation panel. A heat medium distribution portion (11) distributes a thermal medium in inside, when the frame is fixed so that heat transfer is possible. A frame mounting portion (14a,14b) mounts the frame. The heat-medium distribution portion is provided directly under the frame mounting portion.    USE - Mount frame for supportably fixing solar power generation modules in installation surface of roof of building.    ADVANTAGE - The heat transfer of the heat of the solar power generation module can be carried out by heat-medium distribution portion, so that the frame of a solar power generation module can be made into the structure which can be heat-collected only by fixing to the mount frame for solar power generation modules. The solar power generation module can be cooled, and the heat collecting can be perform easily from the frame of a solar power generation module, so that both the heat collecting efficiency of a heat-medium distribution portion and generating efficiency of a solar power generation module can be improved. An electric power generation and heat collecting can be performed simultaneously, the electric power generation amount can be maintained without decreasing the number of installation of a solar power generation module. Since the provided structure requires only few installation areas to collect the heat, the installation cost can be significantly reduced, without affecting the number of installation of a solar power generation module which are arranged in parallel with the existing solar collector. Since an external appearance can be maintained, design value is not impaired. The heat-transfer distance of the frame of a solar power generation module and a heat-medium distribution portion can be made short, so that the heat collecting efficiency of a heat-medium distribution portion can be improved.
