Embodiment 1

[0035] This preferred embodiment provides a tracking method for a solar tracker, figure 1 A preferred flowchart showing the method, as figure 1 As shown, the method includes the following steps:

[0036]S102, control the solar panel of the solar tracker to move to the first position according to the current time parameters and the location of the solar tracker; preferably, determine the position of the sun according to the latitude and longitude of the location and the current date and time, and determine the position of the sun Afterwards, move the solar panel to a plane perpendicular to the incident rays of the sun, or called the first position. Preferably, the position of the sun can be calculated according to the built-in program of the solar tracker controller, or the corresponding data table of the relationship between the sun position and the region and time parameters can be established in advance, and the position of the sun can be determined according to the table l...

Embodiment 2

[0047] Based on the tracking method of the solar tracker in the above-mentioned embodiment 1, this embodiment provides a tracking device for the solar tracker, specifically, figure 2 Show a kind of preferred structural diagram of this device, this device comprises:

[0048] The control unit 202 is used to control the solar panel of the solar tracker to move to the first position according to the current time parameters and the location of the solar tracker; preferably, the position of the sun is determined according to the latitude and longitude of the location and the current date and time, After determining the position of the sun, the solar panel is moved to a plane perpendicular to the incident rays of the sun, or referred to as the first position. Preferably, the position of the sun can be calculated according to the built-in program of the solar tracker controller, or the corresponding data table of the relationship between the sun position and the region and time param...

Abstract

The invention provides a tracking method and device for a solar tracker. The method includes: controlling a solar panel of the solar tracker to move to a first place according to the current time parameters and the current position of the solar tracker; determining the second position of the solar panel according to the parameters obtained by a solar angle sensor of the solar tracker; judging whether the corresponding angle difference of the second position and the first position is in the preset angle range; rectifying the corresponding angle of the first position subject to the corresponding angle of the second position when the corresponding angle difference of the second position and the first position is in the preset angle range according to judgment. By means of the tracking method and the tracking device, the problem that the system is unstable caused by the fact that the hybrid control solar tracker in the prior art is greatly influenced by the environment, and the effect of improving the stability of the solar tracker is improved.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to a tracking method and device for a solar tracker. Background technique [0002] Traditional solar panels have a fixed angle and orientation, which cannot fully and effectively utilize solar energy. If the solar panel can track the sun to ensure that the incident angle of sunlight is perpendicular to the solar panel, the utilization efficiency of the solar energy of the solar panel can be improved. The emergence of solar trackers has solved the above problems well. The solar tracker can track the sun and improve the utilization rate of solar energy. [0003] In the existing solar tracker, there are mainly the following three control methods: [0004] 1) Calculation method: through the local latitude and longitude and time, the controller calculates the angle corresponding to each specific time, and then controls the entire device to rotate to a suitable position. The controller can ...
