Abstract

The invention provides a sun position sensor for a single-axis solar tracking control system. The sun position sensor comprises a shell, a circuit board, a V-shaped baffle plate, at least two and an even number of light sensitive elements with photoconductive effects and a transparent cover, wherein the circuit board is positioned in the shell; a sealed cavity is formed by the shell and the transparent cover; the circuit board is arranged in the shell; the baffle plate is fixedly arranged in the middle of a bottom plate of the shell with an opening facing upwards; the light sensitive elements are symmetrically arranged on two sides of the baffle plate respectively, and are electrically connected with the circuit board; when light rays shoot at right angles from right above, the light sensitive elements cannot receive direct light rays, and the light intensity received by the light sensitive elements on the two sides is consistent; when the light rays irradiate obliquely, light sensitive elements positioned on one side of the baffle plate receive the direct light rays, and the light sensitive elements on the other side cannot receive the direct light rays. By adopting the sun position sensor for the single-axis tracking control system, the detection accuracy and sensitivity of the sensor are increased, high-accuracy tracking of the sunlight position is ensured, and a solar cell panel can gain maximum light intensity.

Description

technical field [0001] The invention relates to the technical field of solar tracking, in particular to a sun position sensor for a single-axis solar tracking control system. Background technique [0002] Concentrating photovoltaic devices and tracking photovoltaic systems need to continuously track and capture the sun's position. The basic principle is to use the output changes of optoelectronic devices to track the direction of the sun's shading changes. [0003] The sensors used in the traditional single-axis solar tracking control system generally have problems such as complex structure and low precision. For example, an existing single-axis photovoltaic power generation system uses a tracking light sensor, which includes a triangular bracket composed of a horizontal base plate and two inclined plates, and two plates mounted in parallel on the two inclined plates and used to filter sunlight The filter lens, the two photoresistors that convert the sunlight filtered by th...
