Resumo: The demand for energy and the pressure for reducing environmental impacts is increasing in developing countries, mainly in agricultural areas. The generation of electricity from photovoltaic panels can be economically and environmentally advantageous as a source of renewable energy and the ability to reach remote consumers. The present study aimed to evaluate the performance of a photovoltaic system equipped with a sun-tracking device, comparing to a fixed panel. The test compared two panels of a photovoltaic cell system, one used a rotation module in two-axis, and the other a fixed one (control), for capturing solar energy throughout the day in a tropical region of Brazil. Solar energy data were obtained in the two photovoltaic panels with data continuously recorded six months, with a weather characteristic of high cloudiness and rainfall indexes. The commissioning of the tested photovoltaic panels was done on bright days. Power results indicated that the two-axis tracker system was useful during the test, presenting an increase of 26% when compared to the fixed panel. It was found that when the cloudiness and the rain index are very high, the sun tracking system might not be as efficient as foreseen. Rainfall and cloudiness index are essential factors for determining the feasibility of using a tracker device in tropical regions.

La generación de electricidad a partir de paneles solares fotovoltaicos puede ser ventajosa económica y ambientalmente como fuente de energía renovable, además de la capacidad de llegar a consumidores en ubicaciones remotas. El presente estudio tuvo como objetivo evaluar el rendimiento de un sistema fotovoltaico equipado con un dispositivo de seguimiento solar en comparación con el panel fijo. Se han implementado dos sistemas fotovoltaicos, uno de los cuales usaba un módulo de rotación de dos ejes y el otro era fijo (control), para capturar energía solar durante todo el día en una región tropical de Brasil. Los datos de energía solar se obtuvieron de los dos paneles fotovoltaicos, con registro constante durante seis meses, lo que demostró una característica climática de altos niveles de nubosidad y precipitación para el período. La puesta en marcha de los paneles fotovoltaicos analizados se realizó en días claros. Los resultados de potencia indicaron que el sistema de seguimiento con dos ejes fue efectivo durante la prueba, mostrando un aumento del 26% en comparación con el panel fijo. Se confirmó que, cuando la nubosidad y el índice de lluvia son muy altas, es posible que el sistema de seguimiento solar no sea tan eficiente como se predijo. La lluvia y la nubosidad son factores esenciales para determinar la viabilidad de utilizar un dispositivo de rastreo en las regiones tropicales.A demanda por energia e a pressão para reduzir os impactos ambientais estão aumentando nos países em desenvolvimento, principalmente nas áreas agrícolas. A geração de eletricidade a partir de painéis fotovoltaicos pode ser econômica e ambientalmente vantajosa como fonte de energia renovável, além da capacidade de alcançar consumidores em locais remotos. O presente estudo teve como objetivo avaliar o desempenho de um sistema fotovoltaico equipado com um dispositivo de rastreamento solar em comparação com o painel fixo. O teste comparou dois painéis de um sistema de células fotovoltaicas, sendo que um utilizou um módulo de rotação em dois eixos e outro era fixo (controle), para captar energia solar ao longo do dia em uma região tropical do Brasil. Os dados de energia solar foram obtidos nos dois painéis fotovoltaicos, com gravação constante por seis meses, o que demonstrou uma característica climática de altos índices de nebulosidade e precipitação para o período. O comissionamento dos painéis fotovoltaicos testados foi realizado em dias claros. Os resultados de potência indicaram que o sistema rastreador com dois eixos foi eficaz durante o teste, apresentando um aumento de 26% quando comparado ao painel fixo. Verificou-se que, quando a nebulosidade e o índice de chuva são muito altos, o sistema de rastreamento solar pode não ser tão eficiente quanto o previsto. As chuvas e o índice de nebulosidade são fatores essenciais para determinar a viabilidade do uso de um dispositivo rastreador em regiões tropicais.Research, Society and Development2020-11-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/963710.33448/rsd-v9i11.9637Research, Society and Development; Vol. 9 No. 11; e1029119637Research, Society and Development; Vol. 9 Núm. 11; e1029119637Research, Society and Development; v. 9 n. 11; e10291196372525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIenghttps://rsdjournal.org/index.php/rsd/article/view/9637/8575Copyright (c) 2020 Filipe de Souza Lins; Vinicius A. da Silva; Irenilza de Alencar Nääs; Nilsa Duarte da Silva Lima; Mário César da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessLins, Filipe de Souza Silva, Vinicius A. da Nääs, Irenilza de Alencar Lima, Nilsa Duarte da Silva Silva, Mário César da 2020-12-10T23:37:57Zoai:ojs.pkp.sfu.ca:article/9637Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:31:51.823770Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
