Proposta de implantação de um sistema de energia solar fotovoltaica no estacionamento da faculdade de tecnologia: uso para redução de consumo de energia e para laboratório

Abstract

There is a worldwide trend today in electricity generation through photovoltaic solar sources, combining the use of a renewable and clean source with the reduction of installation costs. In this work, a photovoltaic solar energy system was proposed and designed to supply electricity to the Faculty of Technology of the Federal University of Amazonas and supply the lamps in the corridors of the unit. For this, on-grid (system connected to the local electrical grid) and off-grid (system independent from the local electrical grid) configurations are taken. Furthermore, the presented system uses AutoCAD software for the design of the solar panels arrangement, used in 4 different technologies and models: conventional monocrystalline (Canadian HiKu6 Mono CS6W-545MS), conventional polycrystalline (Canadian HiKu Perc Poly CS3W-440P ), half-cell (BYD MLK-36 Monofacial Perc half-cell 540W) and bifacial (BYD MLTK-36 Bifacial 540W). In addition, the sizing of the load to be fed by the off-grid system was carried out based on the replacement of existing AC (alternating current, in Portuguese alternating current) lamps by DC (direct current, in Portuguese direct current) lamps of equivalent power of the CP-T812-18W model. With the system proposed here, a reduction in monthly energy consumption in the unit of about 37,408 kWh/month and a reduction in CO2 equivalent gas emissions of 43.28% in the atmosphere is expected; becoming a laboratory so that students can evaluate and learn about the different technologies of solar cells or the type of connection possible.
