Solar energy condensation photovoltaic structure on north-slope roof

The utility model discloses a solar energy condensation photovoltaic structure on a north-slope roof, which comprises a solar energy photovoltaic panel and a compound parabolic collector (CPC) condensation reflecting device installed on the inclined plane of the north-slope roof, wherein the CPC condensation reflecting device comprises a compound parabolic reflection surface; the solar energy photovoltaic panel is vertically arranged on the inclined plane of the roof below the CPC condensation reflecting device; and the compound parabolic reflection surface of the CPC condensation reflecting device is used for reflecting incident sunlight to the accepting surface of the solar energy photovoltaic panel. According to the solar energy condensation photovoltaic structure on the north-slope roof, the problem that the north slope of the traditional building roof is difficult to put a solar energy collector is solved. In a peculiar arrangement mode, the north slope of the building can realize the purpose of collecti
