Automação de correção de incidência solar em módulos fotovoltaicos

Abstract

The follow-up of solar energy has been increasingly used, both in homes and in industries and in agriculture, but the need to increase energy efficiency has been highlighted in recent years, but with high costs, in this context, the objective was to develop a solar declination correction prototype for a photovoltaic system capable of being supported by low-cost rechargeable batteries. The study consisted in assembling a prototype of a photovoltaic structure where its angulation was corrected during the day, the entire development of the experiment was conducted in the automation and electrotechnical laboratory, where all hardware components and all software development were tested. Efficiency tests were conducted outside the laboratory, seeking to ensure that the solar incidence correction prototype and the fixed system use the same energy consumption, testing them with temperature sensors. At the end of the tests, the solar incidence correction system obtained a significant difference when compared to the fixed system. The incidence correction system proved to be efficient when making adjustments during the day, but in its data collection the system that remained fixed had a longer data collection time.
