What is Solar Tracker Technology?

How Does Solar Tracker Technology Work?

Solar tracker technology is a remarkable innovation that enables solar panels to automatically orient themselves for optimal energy capture by following the sun’s trajectory throughout the day. This dynamic functionality sets solar trackers apart from fixed-tilt systems, allowing them to harness solar energy more efficiently.

The core principle behind solar tracker technology is to continuously adjust the position of the solar panels to optimize sunlight exposure, thereby maximizing energy production. This is achieved through the use of advanced control systems that regulate the movement of the panels in alignment with the sun’s path.

There are primarily two types of solar tracker mechanisms:

  • Single-Axis Solar Trackers: These trackers adjust the orientation of the solar panels along one axis, either in the north-south or east-west direction, to track the sun’s apparent movement across the sky.
  • Dual-Axis Solar Trackers: These trackers employ a more sophisticated approach by adjusting the solar panels along both the north-south and east-west axes, allowing for precise tracking of the sun’s position throughout the day and across different seasons.

The choice between single-axis and dual-axis trackers depends on factors such as location, available space, and specific energy generation requirements. Both types of trackers offer distinct advantages and are suitable for different applications.

Furthermore, solar tracker mechanisms can be designed based on astronomical algorithms or utilize light sensors for accurate solar tracking. In addition, advancements in solar tracker technology have led to the development of smart trackers equipped with built-in intelligence to adapt to various weather conditions and optimize energy capture.
