Abstract

The invention relates to a solar tracker. The solar tracker comprises a mechanical part and a control part, wherein the mechanical part comprises a supporting shell body and a horizontal movement device arranged in the supporting shell body, and the control part is arranged at the internal bottom of the supporting shell body; and the control part comprises a sampling circuit, an analog amplifying circuit, an analog-to-digital conversion circuit, a singlechip signal processing system and a stepping motor drive circuit, wherein the sampling circuit is connected with a solar panel and is used for sampling instant charging current of the solar panel so as to obtain an analog current signal, the signal is converted into a digital signal through the analog amplifying circuit and the analog-to-digital conversion circuit and stored to the singlechip signal processing system, and the singlechip signal processing system is connected with the horizontal movement device through the stepping motor drive circuit so as to control the work of the horizontal movement device. According to the solar tracker, the sampling circuit is adopted to detect the instant charging current of the solar panel, the photoelectric conversion effect of the solar panel is truly reflected, and the solar panel is enabled to be always in the best photoelectric conversion state, so that the regulation accuracy is high.

Description

technical field [0001] The invention relates to a solar tracker, in particular to a solar tracker which adjusts the position of the solar panel by detecting the photoelectric conversion effect of the entire solar panel. Background technique [0002] Due to the global energy shortage, people are prompted to look for new alternative energy sources. In the current development of renewable resources, solar energy is an inexhaustible clean energy that is not limited by regions and can be used wherever there is sunshine. At present, all solar equipment uses solar panels (photovoltaic panels) to convert solar energy into electrical energy. The panels are fixed and have a certain inclination. Due to the influence of the earth's rotation and revolution, fixedly placed solar panels cannot change their angles according to changes in light, and the utilization rate is low. In order to optimize the utilization of solar energy by the solar panel, the solar panel needs to be installed on...
