How to choose a smart PV tracking bracket?

The principle of the smart photovoltaic tracker is to make the solar panel change with the angle of the sun and always face the sun, so that the sun's rays shine directly on the solar panel power unit. The use of solar trackers can maximize the power generation efficiency of solar PV modules. How to choose intelligent tracking bracket and fixed photovoltaic bracket every day?


In terms of power station investment, it is necessary to consider the cost and profit factors of the power station, whether to choose a photovoltaic intelligent monitoring bracket or a fixed bracket. If the construction is to increase the cost of the site by 20%, it should ensure that the production capacity is increased by more than 30%, so that the traceability system will have considerable benefits. Therefore, for medium to large projects, the benefits of using smart PV tracking media are very substantial. Intelligent trackers are generally divided into two categories according to the different driving methods: one is automatic tracking of motor control; The second is tracking through physical thermal expansion techniques (passive tracking).


Through optical computer software, mechanical structure testing, and theoretical combing in recent years, the tracker has formed a mature control system. Therefore, astronomical/digital software combined with simple mechanical system management (active tracking) is commonly used to develop professional and reliable products. Active tracking training is currently a good technical and economical approach compared to other solutions.


In addition, the requirements of the PV smart tracking bracket are similar to those of other fixed brackets, and the requirements are also stringent: the robust structure is conducive to withstanding wind pressure, snow pressure, earthquakes, dirt and corrosion, and it has been able to operate in typical environments for more than 25 years. In addition, all support and monitoring systems must comply with certain standards of the project location, including structure, components, compression specifications, environmental indicators, etc. These metrics are forcing tracker manufacturers to conduct more and more research to find better solar tracking support system solutions.


The sensor-based solar emission energy tracking method is called the photovoltaic intelligent tracking support system, so the accuracy of solar tracking can be guaranteed. However, the limitations are also relatively large, and it is only suitable for sunny days. The method of tracking solar ephemeris data associated with the coordinates of the installation site is called an astronomical algorithm. This mode of operation guarantees higher output power and centralized installation of the power plant. This tracking method is also suitable for cloudy conditions and can provide accurate tracking.
