Device for automatically tracing sun by solar cell panel based on geomagnetic field and control method

Abstract

The invention provides a device for automatically tracing the sun a solar cell panel. In the device, the solar cell panel can be vertically and rotatably arranged at the inner side of a U-shaped bracket through a vertical rotation structure, the bottom of the U-shaped bracket can be horizontally and rotatably arranged on a horizontal rotation structure, and the vertical rotation structure and the horizontal rotation structure are respectively connected with a control unit. The method comprises the following steps of detecting geomagnetic field signals in real time by analyzing a sensor collection unit, determining the direction of the sun relative to a cell panel carrier and revising a horizontal direction rotation angle of the cell panel; and revising the horizontal direction rotation angle of the cell panel and regulating a pitching rotation angle of the cell panel to keep the cell panel just face the sun through current time signals output by a clock chip. The invention enables the solar cell panel to always just face the sun, greatly enhances the utilization ratio of solar energy, can be used for fixing solar energy carriers including solar street lamps and solar roof power generation systems, can also be used for movable solar energy carriers such as solar vehicles, and greatly expands the application range of the device.

Description

technical field [0001] The invention relates to a solar battery panel, in particular to a device and a control method for the solar battery panel to automatically track the sun so as to keep the solar battery panel facing the sun all the time so as to improve the utilization rate of solar energy. Background technique [0002] At present, in the installation and use of solar cells, the installation method is fixed and directly installed on the carrier, but the position of the sun is in different directions with the change of time and the movement of the position of the carrier, so the sunlight cannot always shine directly on the solar panel. , resulting in invisible loss of solar energy. And the power loss and corresponding cost increase caused by this method are becoming more and more prominent with the rapid development of solar energy technology. Therefore, in order to promote solar cells on a larger scale, it is increasingly important to improve the utilization rate of s...
