What is the photovoltaic intelligent tracking system? What are the advantages of generating electricity?

Technological innovation promotes the improvement of requirements such as photovoltaic reception, conversion rate, and total power generation. The photovoltaic intelligent tracking system greatly increases the amount of solar radiation received by the photovoltaic array, which promotes the overall power generation of the photovoltaic system. According to a report by a market research company, the global solar automatic tracking system market is expected to reach USD 75.4 by 2023.

Photovoltaic Intelligent Tracking System

1. The principle of photovoltaic intelligent tracking system

The principle of photovoltaic tracking system is actually very easy to understand, because the irradiation angle of the sun is changing all the time. If the tracking technology is applied to the traditional fixed photovoltaic panel, it will not be fixed in one place, but will change with the change of the sun like a sunflower. The solar radiation energy is increased, which further promotes the overall power generation of the power station.

2. What is the photovoltaic intelligent tracking system

Because of the autobiographical movement of the earth, compared with the fixed solar photovoltaic power generation system, the sun rises and sets every day in spring, summer, autumn and winter, and the illumination angle of the sun changes all the time. Only by effectively ensuring that the solar panels can always face the sun, can power generation be guaranteed. Efficiency is at its best.

At present, the photovoltaic intelligent tracking system calculates the angle of the sun at different times of each day according to the longitude and latitude of the placement point, and stores the sun position at each time of the year in PLC, single-chip computer or computer software, that is, by calculating Sun position to achieve tracking.

The theory of computer data needs to be based on the data and settings of the latitude and longitude area of ​​the earth. After installation, it is inconvenient to move and disassemble. After moving the original data and parameters, it has to be reset. The principle, technology, circuit, and equipment are more complicated. Professionals do it.

3. The advantages of photovoltaic intelligent tracking system in power generation

Affected by the earth's rotation and revolution, a fixed point on the earth rotates with the sun's cycle throughout the year, causing the angle of illumination to change constantly. The installation of photovoltaic tracking system is to maintain the change of solar panels with the change of the sun, increase the amount of solar radiation received by the photovoltaic array, and further increase the overall power generation of the solar photovoltaic power generation system.

According to the adjustment angle of the bracket, the photovoltaic tracking system can be divided into three categories, namely flat single-axis, inclined single-axis and dual-axis trackers. According to the calculation, the double shaft can increase the power generation by 40% at most, the inclined single shaft can increase the power generation by 20%-25%, and the flat single shaft can increase the power generation by 10%-20%. Among them, the reliability risk of flat uniaxial is relatively low, while the risk of inclined uniaxial and biaxial is relatively high.

From the perspective of the comprehensive cost performance of the three products of flat single axis, inclined single axis and dual axis tracking system, the flat single axis has more advantages.

China has a vast territory and complex and diverse climatic conditions. Different regions adopt different photovoltaic intelligent tracking systems, and the proportion of increased power generation varies greatly. In general, the higher the latitude, the better the light conditions, and the greater the percentage of improvement: in most areas within 25° north latitude, the increase in power generation is less than 30%; while in the northwest above 35° to 40° north latitude, the light conditions are better. In the region, the power generation can be increased by 35% to 40%.
