Problems solved by technology

At present, most of the small solar power generation devices are fixed devices. The solar photovoltaic panels adopt a fixed angle and position, and cannot automatically move with the sun. Most of the time, the sunlight is irradiated on the photovoltaic panels obliquely. Most of the photoelectric conversion efficiency is about 4%-6%,

Embodiment Construction

[0014] In order to further illustrate the technical means and effects adopted by the present invention to achieve the intended invention purpose, the specific implementation, structure, characteristics and effects of the tracking solar power generation device proposed according to the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] In order to effectively improve the power generation efficiency of the solar battery panel 1, the present invention adopts a photosensitive element automatic tracking device in the east-west direction of the solar battery 1, and the solar battery panel 1 is fixed with a photoreceptor 10 and a baffle plate 9. At this time, the shadow of the baffle plate 9 falls on the west side of the photoreceptor 10 and the east side of the baffle plate 9 receives light, thereby generating a voltage difference output signal, which is controlled by the controller. When irradiated on the solar panel 1, the sh...

Abstract

The invention relates to an automatic tracking solar power generating device, comprising a solar cell and a solar cell bracket, wherein the solar cell is arranged on the solar cell bracket; a photoreceptor is arranged in the east-west direction above the solar cell; the photoreceptor output a signal by means of blocking of a baffle; and the output signal is used for controlling a stepping motor rotating horizontally. The stepping motor drives the solar cell bracket by a gear and semicircular racks so as to carry out swivel adjustment on the east-west angle of the solar cell. The elevation angle of the solar cell bracket and the sun is changed by expansion of an expansion device due to increase and decrease of pressure caused by phase change of an energy-storing medium. Therefore, omnibearing tracking of solar power generation is realized and the sunlight utilization ratio is improved by 30%-50% compared with that obtained by a fixed solar power generating device.

Description

technical field [0001] The invention relates to a tracking device for solar power generation, which belongs to the technical field of solar power generation equipment. Background technique [0002] Solar energy is a non-polluting clean energy. Today, when the whole people pay attention to environmental protection, various devices and equipment using solar energy are emerging. At present, most of the small solar power generation devices are fixed devices. The solar photovoltaic panel adopts a fixed angle and position, and cannot automatically move with the sun. Most of the photoelectric conversion efficiency is about 4%-6%, and 30%-50% of the sunlight is wasted. Although there is also a solar power generation device equipped with a sunlight tracking device, the structure is relatively complicated, and the tracking device itself consumes a lot of energy, thereby affecting the power generation efficiency and popularization of the solar power generation tracking device.
