Embodiment Construction

[0027] List an example below and in conjunction with accompanying drawing the present invention is described in detail:

[0028] Such as figure 1 and figure 2 As shown, a trough-type uniform concentrating single-axis tracking solar photovoltaic power generation device of the present invention is composed of a power generation part composed of two solar panels back to back, a concentrating part composed of a uniform concentrating mirror and a liftable support frame. The tracking part consists of;

[0029] The power generation part is composed of a first solar cell panel 1 and a second solar cell panel 2 fixed on the support plate 4, the side of the first solar cell panel 1 and the second solar cell panel 2 receiving sunlight faces outward, and the backlight One side faces inward, forming a back-to-back parallel structure. The long sides of the first solar cell panel 1 and the second solar cell panel 2 are placed in a north-south direction and symmetrical about the central ax...

Abstract

The invention relates to a groove type light condensing single axis tracking solar photovoltaic power generating device. The groove type light condensing single axis tracking solar photovoltaic power generating device is formed by a power generating portion which is formed by two solar cell panels back to back, a light condensing portion which is formed by uniform light condensing reflectors and a tracking portion which is formed by a lifting supporting frame. According to the groove type light condensing single axis tracking solar photovoltaic power generating device, occupied area is reduced due to the fact that the power generating portion adopts the back-to-back structure and the photovoltaic power generating capacity is indirectly increased; the light condensing portion can enable sunlight to uniformly fall on the solar cell panel after the sunlight is reflected, the energy converting efficiency from solar energy to electric energy and the service life of the solar cell panel are obviously improved; the tracking portion can achieve that the south-north direction is in the best inclination angle and the east-west direction tracks the sun in a single axis mode according to different geographic position conditions, the power generating efficiency is increased substantially, and the solar photovoltaic power generating costs are reduced.

Description

technical field [0001] The invention belongs to the technical field of photoelectric conversion of solar energy, and in particular relates to a trough-type uniform concentrating single-axis tracking solar photovoltaic power generation device. Background technique [0002] Solar energy is rich in resources and widely distributed, and is regarded as the most promising renewable energy in the 21st century. Solar photovoltaic power generation is a technology that relies on the photovoltaic effect and uses solar panels to directly convert solar energy into electrical energy. In China, which is rich in solar energy resources, the potential for its development and utilization is very broad, but due to the high price of solar panel manufacturing materials, the cost of power generation is difficult to compare with traditional power generation. In order to increase the solar energy obtained per unit area, further improve the utilization rate of solar cells and reduce the cost of powe...
