Problems solved by technology

However, from a technical point of view, the uniformity of the concentrated light intensity of the Fresnel lens on a specific surface is relatively poor.
From an industrial point of view, compared to reflective methods, the cost of special lenses is still higher than the cost of reflective mirrors with high reflectivity

Abstract

The invention discloses a reflective light-gathering solar photovoltaic power generation assembly with double parabolic cylinders, which comprises a primary light reflecting body, a secondary light reflecting body, a transparent protection cover plate, a photovoltaic battery, a conductive connecting line, a basal plate of a heat radiator and a frame package. A primary parabolic cylinder reflector is arranged on the primary light reflecting body, and a secondary parabolic cylinder reflector is arranged on the secondary light reflecting body. By the proper combined arrangement and use of the two parabolic cylinder reflectors, light-gathering irradiation which has the same radiation intensity and has the same included angle with the surface of the photovoltaic battery is formed at the surface of the photovoltaic battery, so that the photoelectric transformation efficiency of a common photovoltaic battery in unit area is enhanced, the light-gathering ratio of higher times is even reached, and the aim of using less photovoltaic batteries under a condition of given power is achieved, thereby lowering the total cost of a photovoltaic power generation system. The assembly can be used for one-dimensional inclined shaft tracking, can enhance the power generation capacity by tracking and also plays the role of lowering the total cost of the photovoltaic power generation system.

Description

technical field [0001] The invention relates to a structure of a photoelectric conversion module of a concentrating photovoltaic system, which belongs to the technical field of solar energy utilization, in particular to a double parabolic cylindrical reflective concentrating solar photovoltaic power generation assembly. Background technique [0002] The development of new energy and renewable clean energy is a common issue faced by the whole world. In the development and utilization of new energy, photovoltaic power generation has attracted much attention. At present, photovoltaic power generation mainly adopts ordinary flat-panel photovoltaic power generation system. Ordinary flat-panel photovoltaic power generation systems directly place flat-panel solar cell components towards low-latitude regions (at a certain angle to the ground), and form solar photovoltaic arrays in series and parallel to achieve the purpose of using solar power to generate electricity. In an ordinar...
