Recent developments in solar tracker systems include exploring different module geometries, materials, and tracking mechanisms to boost efficiency. Single-axis and dual-axis tracking systems are widely used, with dual-axis systems offering greater efficiency and accuracy.
Solar tracking systems (TS) improve the efficiency of photovoltaic modules by dynamically adjusting their orientation to follow the path of the sun. The target of this paper is, therefore, to give an extensive review of the technical and economic aspects of the solar TS, covering the design aspects, difficulties, and prospects.
Solar trackers move the payload towards the sun throughout the day. In this paper different types of tracking systems are reviewed and their pros and cons are discussed in detail. The results presented in this review confirm that the azimuth and altitude dual axis tracking system is more efficient compared to other tracking systems.
Their comparison of curves from these different solar tracking systems showed that the increase in annual radiation gain from the double axis tracker, vertical axis tracker and tilted axis tracker over the fixed tilt system were 30%, 18% and 11% respectively.
Conclusion and future outlook Solar trackers are compact solar energy collecting systems that are used to increase the amount of collectible solar energy of the PV systems by tracking the position of the sun across the sky at all times.
Developed a prototype of a DAS tracking system with IoT integrated controller that outperforms fixed solar systems by 9.4 % (Koodalsamy et al., 2023). Electronics and mechanics are the two main components of the system.
