Photovoltaic tracking system

At present, there are three kinds of solar photovoltaic automatic tracking systems that are widely used, including horizontal single-axis tracking, tilt-latitude angle-inclined single-axis tracking and dual-axis tracking. Among them, horizontal single-axis tracking and tilting single-axis tracking have only one rotational degree of freedom, and dual-axis tracking has two rotational degrees of freedom. The tracking control strategy adopted by the three tracking systems is an active tracking control strategy, which calculates the position of the sun in the sky and controls the orientation of the photovoltaic array. This active photovoltaic automatic tracking system can be better applied to the environment with more frost, snow and sand, and can also work reliably in unattended photovoltaic power plants. From the perspective of whether the tracking is continuous, the developed photovoltaic automatic tracking system adopts the step tracking method. Compared with the continuous tracking method, the step tracking method can greatly reduce the energy consumption of the tracking system itself.

A properly designed photovoltaic tracking system can increase the efficiency of the entire system by 40%, while the power consumption of the motor itself is only 20kwh a year, and the cost is low and installation is convenient.
