Análise de eficiência de painel fotovoltaico com sistema tracker seguidor solar

Abstract

Increasing the efficiency of solar capture in photovoltaic panels can be obtained through automated systems of solar trackers. The present study aims to measure efficiency gain in a solar tracker solar panel system compared to a traditional fixed system. To carry out the work, a prototype of an automated solar tracker and a data collection system were developed, both on Arduino platforms, allowing a direct comparison between the energy generation of a solar tracker and a fixed photovoltaic panel. The prototype showed significant power gains during the day, especially in the first and last hours of sunshine. Featuring up to 30% gains in some periods of the day. It is concluded that a photovoltaic system with solar tracker can be a good option to guarantee an increase of energy capture efficiency in cases that an optimization of the system is necessary.
