An automatic solar tracking system (STS) is an emerging technology that rotates a solar panel or solar concentrator to various positions throughout the day by monitoring the current position and path of the sun.
The performance of the dual-axis photovoltaic tracking system outperforms that of the stationary systems by more than 27% based on the overall system efficiency. Under diverse weather conditions, the efficiency of the scheduled-based solar tracking systems was enhanced by 4.2% compared with that of the light-dependent resistor-based solar trackers.
Automatic STS rely on accurate sun tracking, which can be affected by environmental factors such as clouds, haze, and shading from nearby structures or vegetation. These factors can impact the system's ability to track the sun accurately and affect energy generation.
The main aim of any automatic STS is to maximize the amount of sunlight that the solar concentrator or module will receive, resulting in the maximization of the overall energy outputs of the system. Solar tracking can be performed in two ways: single-axis tracking and double-axis tracking.
The solar energy market is represented mainly by PV panels, the capacity of which is increasing annually as they are relied upon as a promising alternative to fossil fuels (Ali et al. 2025;
