Problems solved by technology

Photovoltaic power generation systems can provide more electric energy by using sun-tracking devices. However, only a small number of photovoltaic power generation systems in my country have adopted sun-tracking devices. The devices that have been implemented have disadvantages such as complex structure, difficult implementation, and low tracking accuracy, so that they cannot be widely used. use

Embodiment Construction

[0048] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0049] In the embodiment of the present invention, figure 1 , 2 A solar device shown includes a solar panel 1, a solar azimuth tracking device 2, a solar height tracking device 3, and a fixed bracket 4. The solar azimuth tracking device 2 is mounted on the fixed bracket 4 through a rotating bearing and is based on the sun. The azimuth angle of the light adjusts the inclination angle of the solar panel 1 through overall rotation. The sun azimuth tracking device 2 includes an azimuth shaft 201, an azimuth rotating gear 202 concentrically fixed with the azimuth shaft 201, and a meshing transmission...

Abstract

The invention discloses a solar device and a control method thereof and relates to the technical field of solar power generation. The solar device comprises solar battery panels, solar-azimuth tracking devices, solar-altitude tracking devices and fixed brackets, wherein the solar-azimuth tracking devices are arranged on the fixed brackets by rotary bearings and can adjust the inclination angles ofthe solar battery panels by whole rotation on the basis of solar azimuth angle; the solar-altitude tracking devices are fixed on the solar-azimuth tracking devices and can adjust the pitch angles ofthe solar battery panels on the basis of solar altitude angle. The solar device disclosed by the invention has the beneficial effects that the solar azimuth can be tracked by high accuracy; meanwhile,by adoption of a modular transmission structure, convenience is brought for expansion of the solar battery panels, and even under the condition of a large quantity of solar battery panels, highly-consistent movement of all the solar battery panels can be still realized only by 2 motors, so that the maximum solar-energy utilization efficiency is realized.

Description

Technical field [0001] The invention belongs to the technical field of wireless solar power generation, and particularly relates to a solar device and a control method thereof. Background technique [0002] The main function of photovoltaic power generation system is to convert solar radiation energy into electrical energy. The sun tracking device is a solar light intensity azimuth tracking component that improves the efficiency of the photovoltaic power generation system. The function is to make the solar photovoltaic panel always face the sun vertically, so that the solar panel can obtain the maximum solar radiation energy. The photovoltaic power generation system adopts the sun tracking device to provide more power. However, currently only a few photovoltaic power generation systems in my country use the sun tracking device. The implementation of the device has the disadvantages of complex structure, difficult implementation, and low tracking accuracy, so that it is not univer...
