Abstract

The invention discloses a solar power generation apparatus. The solar power generation apparatus comprises a supporting base, wherein the supporting base is connected with a supporting inclined plate; a speed reducer is fixedly mounted on the supporting inclined plate; a stepper motor is fixedly mounted on the speed reducer; the output shaft of the speed reducer is connected with a polar shaft; one end of the polar shaft is rotationally connected with a fixed sleeve; a linear motor is fixedly mounted on the fixed sleeve; the output shaft of the linear motor is rotationally connected with a power generation assembly; the power generation assembly comprises a frame body; a tapered groove is formed in the frame body; multiple light cones for focusing solar rays are mounted in the tapered groove in an array manner; Fresnel lenses are mounted on the upper surfaces of the light cones; solar cell chips are mounted at the bottoms of the light cones; an aluminium substrate is mounted at the bottoms of the solar cell chips; a radiating plate is tightly adhered to the bottom of the aluminium substrate; and an insulator is mounted below the radiating plate. The solar power generation apparatus provided by the invention can realize solar tracking power generation; and meanwhile, the power generation assembly is small in volume, light in the overall weight, and stable in operation.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a solar power generation device. Background technique [0002] In recent years, the rapid development of renewable energy technologies based on solar energy and wind energy, especially based on solar power generation technology, has provided new broad prospects for solving energy problems in the future. In order to further reduce costs, the research on solar concentrating systems has been intensified. At present, concentrating solar power generation technology is mainly reflected in CPV concentrating photovoltaics. [0003] Concentrating photovoltaic (CPV) is a representative of new solar power generation technology. Because of its high photoelectric conversion efficiency, CPV occupies a smaller area than concentrated solar thermal power generation, and has huge room for development in the future. It can be used to build large-scale solar power g...

Problems solved by technology

[0004] Although the efficiency of concentrated photovoltaic power generation is much higher than that of photovoltaic panels, concentrated photovoltaic power generation is not easy to miniaturize, especially the thickness is not easy to make thin; this leads to the large volume of concentrated photovoltaic power generation devices with tracking components , heavy weight, unstable operation, and cannot generate electricity reliably
