The invention relates to the photovoltaic power generation technology, and aims at providing a compact double reflection-type photovoltaic condenser based on compound eyes. The compact double reflection-type photovoltaic condenser based on the compound eyes comprises a photovoltaic cell and an optical collector, wherein the upper surface of the optical collector comprises a free curved surface and a refraction curved surface, the lower surface of the optical collector comprises a transmission plane and a reflection plane, the center of the refraction curved surface and the center of the reflection plane are positioned at the same vertical position, the center of the free curved surface and the center of the transmission plane are positioned at the same vertical position, and the free curved surface is arranged at a focal position of the refraction curved surface; and the photovoltaic cell is arranged outside the optical collector and adjoins to the transmission plane, the photovoltaic cell is positioned at a focal position of the free curved surface, and the aperture of the transmission plane is larger than that of the photovoltaic cell. The compact double reflection-type photovoltaic condenser has the advantages that the photovoltaic conversion efficiency of the photovoltaic cell is improved, the service life of the photovoltaic cell is prolonged, an optical plastic PMMA (polymethyl methacrylate) is adopted and is prone to injection molding and processing, light in weight and applicable to large-scale processing, and the processing cost is reduced.
