A Single Axis Solar Tracker is an intelligent solar mounting system that automatically rotates photovoltaic (PV) modules from east to west throughout the day, allowing the panels to follow the sun's movement. Compared with fixed-tilt mounting systems, a single-axis tracker significantly increases solar energy capture and improves the overall performance of photovoltaic power plants.
As global demand for renewable energy continues to grow, utility-scale solar projects increasingly adopt horizontal single-axis trackers to maximize electricity generation while reducing the Levelized Cost of Energy (LCOE).
The working principle of a single-axis solar tracker is based on continuously adjusting the orientation of solar panels to maintain the optimal angle toward sunlight.
Kseng Energy's tracker combines an astronomical algorithm with AI-based closed-loop control, enabling the system to calculate the sun's position in real time and automatically drive the tracker to the most efficient angle.
The system mainly consists of:
Solar PV modules
Torque tube
Drive motor
Slewing drive
Controller
Sensors
Communication system
During sunrise, the tracker begins rotating from the east. Throughout the day, the controller continuously adjusts the panel position according to the sun's trajectory. At sunset, the tracker automatically returns to its initial position, preparing for the next day.
This intelligent tracking process maximizes daily solar irradiation and minimizes energy loss caused by suboptimal panel angles.
According to the Kseng Energy technical specifications, the Single Axis Solar Tracker provides outstanding performance for utility-scale solar farms.
