Novo radiômetro solar em topologia fly-eye produzido por manufatura aditiva

Abstract

The use of solar generation has been increasingly widespread in Brazil in recent years due to it being a clean generation method, as well as the fact that Brazil is located in a region where solar irradiance is conducive to electricity production. For a photovoltaic system to perform well, the choice of location for its installation is crucial. This work proposes a solar radiometer with a fly-eye topology, resembling the eye of a fly. This technique, which draws inspiration from nature for technological development, is called biomimetics. The developed radiometer is of a reduced scale, allowing for greater mobility of the equipment and versatility of the structure since it is modeled using additive manufacturing and is easy to assemble and disassemble. It also includes a commercial pyranometer as a self-calibrator for the cells. With this equipment, it is possible to understand the dynamics of solar radiation during different times of the year and to confirm that the location where a photovoltaic generation system is intended to be installed is favorable for achieving the expected system performance. This equipment is an improvement on the work of student Lucas Barbosa da Silva.
