The heat in the heat collecting part 5 is conveyed to the inside of the heat collecting part 5 by being communicated with the inside of the heat collecting part 5 by natural convection and forcedly flowing. Heat is prevented from being trapped, and the solar cell panel 2 can be cooled even more efficiently. Further, in this case, the air flow discharged from the heat collecting unit 5 is guided to, for example, a heat collecting tank and is used for hot air heating or the like, so that the efficiency of using solar heat can be further increased.
