ESTUDO DA EFICIÊNCIA ENERGÉTICA DE CÉLULAS FOTOVOLTAICAS EM FUNÇÃO DA RADIAÇÃO SOLAR NO CENTRO-OESTE BRASILEIRO

Amaury de Souza, Flavio Aristone

Resumo


Para o presente trabalho foi desenvolvido um estudo de um sistema fotovoltaico, com armazenamento de energia, na Universidade Federal de Mato Grosso do Sul, Campus Campo Grande, durante o ano de 2014. Foi avaliada a eficiência de painéis fotovoltaicos em função dos valores da componente de radiação solar global no plano horizontal de incidência; das temperaturas ambiente e de operação do painel; e da tensão e corrente do sistema fotovoltaico. Os resultados mostram que a eficiência média mensal oscilou entre 8,65 e 9,17%, com média anual de 8,84%. O módulo apresentou eficiência média 50% inferior aos valores propostos pelos fabricantes.

Palavras-chave: Eficiência Fotovoltaica Celular; Radiação Solar; Conversão da Irradiação Solar; Temperatura da Célula Fotovoltaica.


STUDY OF ENERGETIC EFFICIENCY OF PHOTOVOLTAIC CELLS AS A FUNCTION OF SOLAR RADIATION IN BRAZIL’S MIDWEST REGION

ABSTRACT
In this paper, we developed a study of a photovoltaic system (PV) with energy storage installed at the Federal University of Mato Grosso do Sul, campus of Campo Grande, during 2014. It has been evaluated the efficiency of photovoltaic panels according to the data of the solar radiation components in the horizontal plane of incidence, the local and operating temperatures, and the current - voltage response of the PV system. The results show that the average monthly efficiency oscillated between 8.65% and 9.17%, with an annual average of 8.84%. The modules showed an average efficiency that is 50% smaller compared to the values provided by manufacturers.

Keywords: Photovoltaic Cell Efficiency; Solar Irradiation; Conversion of Solar Irradiation; Photovoltaic Cell Temperature.

RESUMEN
En el presente trabajo se ha desarrollado un estudio para un sistema fotovoltaico con almacenamiento de energía, durante el año 2014 en el campus de Campo Grande de la Universidad Federal de Mato Grosso do Sul. Se evaluó la eficiencia de paneles fotovoltaicos en función de los valores de la componente de radiación solar global en el plano horizontal de incidencia; de las temperaturas ambiente y de funcionamiento del panel; y de la tensión y corriente generada en el sistema fotovoltaico. Los resultados muestran que la eficiencia media mensual osciló entre 8.65% y 9.17%, con una media anual de 8.84%. El módulo ha presentado una eficiencia media 50% inferior a los valores propuestos por los fabricantes.

Palabras clave: Eficiencia de Células Fotovoltaicas; Irradiación Solar; Conversión de Irradiación Solar; Temperatura de las Células Fotovoltaicas.
