Cassegrain structure-based high-power solar concentrator array system

Abstract

The invention belongs to the field of solar photovoltaic power generation technology application, and aims to provide a Cassegrain structure-based high-power solar concentrator array system. Due to a bionic structure of apertures of concentrators, the concentrators are seamlessly distributed in an array manner. The system comprises a cubic base and a plurality of Cassegrain structure-based solar concentrators of which the apertures are regularly hexagonal, wherein each Cassegrain structure-based solar concentrator comprises a regularly hexagonal parabolic concave surface reflector, an annular heat radiation sheet, a silica gel gasket, a fixed substrate, a solar battery, a light unifying column, a dual curved convex surface reflector and a planar glass cover board; and a plurality of the honeycomb-type Cassegrain structure-based solar concentrators can be spliced seamlessly. According to the system, green energy can be used fully, and fossil energy danger and ecological environment deterioration can be effectively relieved.

Description

technical field [0001] The invention relates to the application field of solar photovoltaic power generation technology, in particular to a solar concentrator seamless array system based on a Cassegrain structure. Background technique [0002] With the development of industry, the pollution of fossil energy to the ecological environment is becoming more and more serious. Therefore, the use of green energy to replace fossil energy has become a hot spot of concern. As a kind of green energy, solar energy has been widely used in the fields of power generation and heat supply due to its inexhaustible and inexhaustible advantages. However, the low energy flux density of solar radiation to the earth's surface is a disadvantageous factor for the use of solar energy. In order to improve the utilization rate of solar energy and reduce the cost of solar power generation, various concentrators have been developed. At present, the processing and testing technology of large-aperture opt...

The public date is 2010.06.02, the public patent number is CN101719738A "High Efficiency Solar Concentrating Photovoltaic System" and the public date is 2011.06.01, the public patent number is CN201854212 "Closed Spherical Cavity Lighting Concentration Multiplication Solar Power Generation Device" and other patents The calibers of the solar concentrators are all circular. This circular caliber is limited by its own shape and cannot achieve seamless arraying between the concentrators.

This slit concentrator array reduces the efficiency of solar energy utilization, and the structure is bulky, which increases the burden on the two-dimensional solar tracking system and increases the cost of solar energy utilization, which is not conducive to the development of solar energy industrialization
