Abstract

The invention relates to a solar tracking device and a control method. The solar tracking device is provided with a base and a motor fixed on the base through a bolt, a support is fixedly connected to an output shaft of the motor, a solar panel is arranged on the support in a supporting mode, the bottom edge of the solar panel is in contact connection with the base through balls, the solar tracking device further comprises a controller for controlling the motor to work, the signal input end of the controller is connected with an output electrode of the solar panel through a wire, the power output end of the controller is connected with the power input end of the motor through a power line, and the control signal output end of the controller is connected with the control signal input end of the motor through a signal line. The control method includes the steps of conducting angle adjustment according to the output power of the solar panel, and controlling sunlight to perpendicularly irradiate the solar panel always. According to the solar tracking device and the control method, the solar power generation rate can be improved, more than 20% of power can be generated compared with solar cells at the fixed positions, a system is simple and easy to achieve, convenience is brought to use, the performance cost ratio is high, and the electric power cost of remote areas, power shortage areas and temporary power utilization conditions can be effectively reduced.

Description

technical field [0001] The present invention relates to a solar energy system. In particular, it relates to a solar tracking device and a control method for a photovoltaic off-grid power generation system. Background technique [0002] In today's increasingly scarce energy and increasingly serious environmental pollution, finding new and clean energy has become the focus of scientists around the world, among which the use of solar energy is the cleanest and most reasonable. With the maturity of technology and the improvement of technology, the solar photovoltaic industry can be commercialized, its cost is getting lower and lower, and its efficiency is getting higher and higher, which can basically meet the needs of daily life. [0003] Solar cells can use solar energy with maximum efficiency only when sunlight is irradiated vertically on the solar panel. In order to solve this problem, a solar tracking device is now available to ensure that the sunlight is irradiated vertic...
