I. What is PV tracking system?
PV tracking system is a device that adjusts the spatial angle of the PV module plane through the joint action of mechanical, electrical and electronic circuits and procedures to achieve tracking of incident sunlight in order to improve the power generation of PV modules, also known as sunward tracking system, sun-chasing tracking system and sun tracker.
Second, what is the PV reverse tracking system
PV reverse tracking system is actually when the adjacent components in the photovoltaic array is blocked by the reverse adjustment to eliminate the shadow blocking device.
Three, the role and significance of PV reverse tracking
As the PV tracking system is to achieve the tracking of the sunlight incidence angle, so as to achieve the maximum amount of radiation received by the PV module. Usually PV arrays are closely arranged, in order to achieve the maximum income of the PV power plant will not make the array spacing is very large, therefore, if the PV tracking process is only mechanical forward adjustment, then in the PV tracking process the back row of the array will inevitably be blocked by the array from the front row, and in order to eliminate this blocking, it is necessary to make the PV tracking system reverse adjustment, so that the PV array between The PV tracking system needs to be adjusted in the opposite direction so that the PV arrays do not block each other.
It is because of such a positive and negative regulation that the PV tracking system can ensure that there is no shading between the arrays, but also to achieve the maximum radiation received by the PV power plant, so as to achieve the maximum revenue of the tracking PV power plant.
To sum up, the role of PV reverse tracking is to provide a negative feedback to the PV tracking system, so that the PV tracking system can be both positive and negative regulation, so as to maximize the benefits of PV tracking system.
