Problems solved by technology

At the same time, solar energy is also unstable. Because the earth's surface is affected by day and night, seasons, geographical latitude, and random changing climate and natural conditions, the solar energy reaching a certain point is intermittent, and the direction and intensity of sunlight change continuously with time. These defects limit the large-scale development and utilization of solar energy resources

Abstract

The invention relates to a novel double-axis type sun tracking system control circuit which is mainly composed of a tracking module, a single chip microcomputer controller and a driving module. The tracking module is composed of a photoelectric detection module and a sun angle tracking module. A global position system (GPS) module provides required data for the sun angle tracking module. The photoelectric detection is conducted through a photoelectric sensor. The driving module drives a stepping motor 1 and a stepping motor 2 to run to control a rotating disc to rotate in the horizontal direction and the vertical direction to achieve automatic sun tracking. The wind speed and direction, and the illumination intensity and the solar battery parameters are detected in real time during tracking. A double-axis type automatic sun tracking system is adopted, the photoelectric tracking and the sun angle tracking are adopted, the system is stable, and the accuracy is higher.

Description

technical field [0001] The invention relates to the field of a solar power generation device, in particular to a control circuit of a novel dual-axis sun tracking system. Background technique [0002] The total amount of solar energy resources is very large. It is not only a primary energy source, but also a renewable energy source. It is a three-dimensional clean energy that is free to use and does not need to be transported. However, solar energy is dispersed. Although the total amount of solar radiation reaching the earth's surface is huge, its energy flux density is low. There is only about 1000W of solar energy per square meter on the ground. At the same time, solar energy is also unstable. Because the earth's surface is affected by day and night, seasons, geographical latitude, and random changing climate and natural conditions, the solar energy reaching a certain point is intermittent, and the direction and intensity of sunlight change continuously with time. These ...
