Application of solar tracking systems for enhancing the energy yield of photovoltaic modules: a review

Abstract

This paper presents a classification of solar trackers, their types, and the advantages and disadvantages of various algorithms for tracking the Sun’s daily movement. It is demonstrated that ensuring an optimal tilt angle of photovoltaic modules is one of the primary factors influencing the amount of electricity generated by solar power plants. Moreover, the economic benefits of their use are significant, as an increase in the generated electricity can enhance the profitability of investments in generation systems. The conducted studies indicate that efficiency improvements depend on the classification of the selected tracker based on its degrees of freedom, the tracking algorithm, and the installation site.
