Intelligent Sun-Tracking System for Efficiency Maximization of Photovoltaic Energy Production

This paper focuses on the optimization of the electric energy production by photovoltaic cells through the development of an intelligent sun-tracking system. The developed tracking system is innovative in relation to the usual sun tracking systems available in the market. In fact, the developed solution has many advantages in relation to similar existing devices, as this system is autonomous regarding the information needed to process the optimal orientation and is intelligent in a way that it performs on-line monitoring of the photovoltaic energy production. An experimental prototype was built and field results have proven the good performance of the developed tracking system.
