A solar tracker is a system, not just a mechanical structure. The solar tracking system market includes the mechanical drive (rotator), the controller (CPU), the sensors (for sun position or wind), and the communication network (to connect trackers). The solar tracking system market for "slew drives" (worm gear) are the most common mechanical drive. The solar tracking system market for "hydraulic" and "electric" actuators are also used. The solar tracking system market for "centralized" vs. "decentralized" control architectures is a design choice.

The broader solar pv tracker market includes these systems. The solar tracking system market for "controllers" receive commands from a central computer (SCADA) and send them to the drive. The solar tracking system market for "wireless" communication (Zigbee, LoRa) between trackers reduces wiring. The solar tracking system market for "daisy-chain" wired communication is also common. The solar tracking system market for "algorithm" is stored in the controller.

The solar tracking system market for "sensors" include "inclinometers" (to measure tilt angle), "wind sensors" (anemometers), and "sun sensors" (photodiodes). The solar tracking system market for "limit switches" prevent over-rotation. The solar tracking system market for "parking" sensors locate the home position. The solar tracking system market for "safety" sensors (e.g., for maintenance) are also used.

The solar tracking system market for "power" for the trackers is usually taken from the solar array (DC). The solar tracking system market for "battery" backup ensures the tracker can stow in high winds at night. The solar tracking system market for "standby" power consumption is a concern.

The solar tracking system market for "software" includes the central control platform (SCADA) that monitors all trackers. The solar tracking system market for "data" logging records tracker position, wind speed, and any faults. The solar tracking system market for "remote" access allows troubleshooting from anywhere.

Looking ahead, the solar tracking system market will see the adoption of "AI" for predictive maintenance. The solar tracking system market for "edge" computing (processing data on the tracker) will reduce bandwidth. The solar tracking system market for "cybersecurity" for the control network will be important.
