Currently, research into automatic solar trackers is on the rise, as solar energy is abundant in nature, but its use in a highly efficient way is still lacking. This paper provides a detailed literature review and highlights some key advancements and challenges associated with state-of-the-art automatic solar tracking systems.
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 most studied tracker is an azimuth-altitude dual-axis solar tracking system. This type of solar tracker can capture more sunlight during the day, which results in higher energy output. Such a tracker can automatically adapt to seasonal changes in the tilt of the Sun, which is a great advantage compared to other types.
These efforts emphasize the significance of enhancing solar panel efficiency and energy production with sophisticated tracking and control systems. Recent developments in solar tracker systems include exploring different module geometries, materials, and tracking mechanisms to boost efficiency.
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 active method of controlling a solar tracker is a complex system based on the use of programmable controllers, various optical sensors, mathematical models for calculating the coordinates of the Sun and navigation sensors. This methodology enables accurate and efficient solar tracking, allowing for maximum solar energy capture (Fig. 6) .
