PV Tracking Systems: Systems enabling maximum solar panel energy generation. 

PV tracking systems, in a general sense, encompass all technologies designed to move a solar panel array to follow the sun. This broad category includes single-axis, dual-axis, and other specialized tracking mechanisms.

Working Principle: Trackers utilize a control system that can be either "open-loop" (using a pre-programmed algorithm based on location and time) or "closed-loop" (using light sensors to detect the sun's position in real time). This system sends signals to motors or actuators, which physically move the panels.

Key Components: The core components of any PV tracking system include the mechanical structure (racking), the drive system (motors or linear actuators), the control unit (controller and sensors), and the power source.

Market Growth Drivers: The adoption of PV tracking systems is being driven by the global push for renewable energy, falling costs of solar technology, and the desire to increase the efficiency and economic viability of solar projects.
