Solar tracker

Abstract

The invention provides a solar tracker and belongs to the field of solar collection equipment. The solar tracker comprises a sliding seat. A sun-exposure panel is installed at the upper end of the sliding seat, the four directions of the sun-exposure panel are provided with a temperature sensor respectively, and the temperature sensors are connected with a temperature analysis module connected to a motor control module. The solar tracker is capable of tracking the sun so as to guarantee that the solar collection side directly faces the sunlight, and the solar tracker is simple in structure and low in cost.

Description

technical field [0001] The invention relates to the field of solar energy collection equipment, in particular to a solar tracker that can automatically determine the direct sunlight direction and track the sun. Background technique [0002] With the rapid development of world industry, the energy problem is becoming more and more serious. Therefore, the development of energy-saving technology and new energy has become a major project for the sustainable development of mankind. Among them, technologies such as wind energy, tidal energy, and solar energy have been industrialized and achieved good energy-saving results. Especially for solar energy technology, it mainly consists of two aspects: solar water heaters and photovoltaic power generation. The former has been popularized by ordinary people, while the latter is widely seen in power plants, street lamps, and enterprises. [0003] For the field of solar energy technology, its solar energy collection efficiency is an ext...

Problems solved by technology

One is to use a set of clock-type mechanical system that can be pre-adjusted to drive the photovoltaic panel to rotate in real time as the time of the day passes. This kind of system is usually debugged by the debugging master during installation according to the longitude and latitude of each place. After the debugging is completed, The tracking system operates in real time according to the principle of the clock system, and drives the photovoltaic panels in real time to ensure that they are facing the sun in real time. This kind of system is usually more troublesome to install. Once the location is moved, professionals need to re-adjust the tracking system, which is very inconvenient , and tracking is not available on mobile devices

The second is the sensing tracking system. Its main principle is that multiple photoelectric sensors are distributed around a tracking head, and the position of the sun is calculated according to the current difference fed back by each photoelectric sensor. The problem with this type of system is that each photoelectric sensor The lighting area of ​​the sensor is very limited, basically it is point lighting, and due to various reasons, the sunlight varies greatly at each point, so the sensing accuracy of the photoelectric sensor is very limited
