Fixed-tilt PV systems serve as a baseline, with single-axis trackers achieving 20–35% higher energy yield, and dual-axis trackers offering energy gains ranging from 30% to 45% depending on geographic and climatic conditions. When installing a photovoltaic system, the choice of panel tilt is a key aspect in optimizing energy production. While the traditional tilt of about 30-33° is designed to maximize solar irradiation during the middle hours of the day, vertical installation (90°) offers unique advantages, especially. The study systematically classifies solar trackers based on tracking axes (fixed, single-axis, and dual-axis), drive mechanisms (active, passive, semi-passive, manual, and chronological), and control strategies (open-loop, closed-loop, hybrid, and AI-based). The axis can be horizontal (most common), tilted, or even vertical. The surface can be rotated around each axis (tilted) to achieve an appropriate angle with respect to the. Horizontal single axis trackers (HSAT) rotate on a single fixed axis with motor-powered tubes. They capture significantly more energy than fixed systems while maintaining relatively moderate complexity and cost.
