Resumo: | This work presents a performance study of a hybrid photovoltaic/thermal system (PVT), comparing it with a traditional photovoltaic system (PV). The electrical and thermal power, efficiency and energy produced by the systems were analyzed. The photovoltaic module (PV) used was the MSX 77 of the SOLAREX brand, composed of polycrystalline solar cells, whose peak power is 77 Watts. The PVT system analyzed was of the type PVT-liquid, composed of the same PV module and a flat solar collector of the plate type, the water supply of the collector was of the type forced by gravity. In order to determine the characteristic curves of the PV module and, consequently, the maximum electrical power generated, a load bank formed by power resistors was developed. The thermal power was quantified by measuring the water flow that fed the collector and the temperature difference of the inlet and outlet water. With the powers and solar radiation incident on the systems, the efficiencies were determined. The PVT system reduced the temperature of the PV module, increasing the efficiency of electrical generation, providing an increase in the order of 6.9% in the average daily electrical energy. The PVT system, in addition to providing an increase in electrical energy, also provides thermal energy with a higher efficiency than electrical. The heated water can be used to feed water heating systems for bathing, helping to reduce the consumption of electricity in a home. |

Se analizó la potencia eléctrica y térmica, la eficiencia y la energía producida por los sistemas. El módulo fotovoltaico (PV) utilizado fue el MSX 77 de la marca SOLAREX, compuesto por células solares policristalinas, cuya potencia máxima es de 77 Watts. El sistema PVT analizado fue del tipo PVT-líquido, compuesto por el mismo módulo fotovoltaico y un colector solar plano del tipo placa, el suministro de agua del colector fue del tipo forzado por gravedad. Para determinar las curvas características del módulo fotovoltaico y, en consecuencia, la potencia eléctrica máxima generada, se desarrolló un banco de carga formado por resistencias de potencia. La potencia térmica se cuantificó midiendo el caudal de agua que alimentaba el colector y la diferencia de temperatura del agua de entrada y salida. Con los potencias y la radiación solar incidente en los sistemas, se determinaron las eficiencias. El sistema PVT redujo la temperatura del módulo fotovoltaico, aumentando la eficiencia de la generación eléctrica, proporcionando un aumento del orden del 6,9% en la energía eléctrica diaria promedio. El sistema PVT, además de proporcionar un aumento de la energía eléctrica, también proporciona energía térmica con una eficiencia superior a la eléctrica. El agua calentada se puede utilizar para alimentar sistemas de calentamiento de agua para el baño, lo que ayuda a reducir el consumo de electricidad en un hogar.Este trabalho apresenta um estudo de desempenho de um sistema híbrido fotovoltaico/térmico (PVT), comparando-o com um sistema fotovoltaico tradicional (PV). Foram analisadas a potência elétrica e térmica, a eficiência e a energia produzida pelos sistemas. O módulo fotovoltaico (PV) utilizado foi o MSX 77 da marca SOLAREX, composto por células solares policristalinas, cuja potência de pico é de 77 Watts. O sistema PVT analisado foi do tipo PVT-líquido, composto pelo mesmo módulo PV e um coletor solar plano do tipo placa, a alimentação de água do coletor foi do tipo forçada por gravidade. Para determinar as curvas características do módulo PV e por consequência a potência elétrica máxima gerada, foi desenvolvido um banco de carga formado por resistores de potência. A potência térmica foi quantificada aferindo a vazão da água que alimentava o coletor e a diferença de temperatura da água de entrada e saída. Com as potências e a radiação solar incidente sobre os sistemas, foram determinadas as eficiências. O sistema PVT proporcionou a redução da temperatura do módulo PV, aumentando a eficiência de geração elétrica, proporcionando um aumento na ordem dos 6,9% na energia elétrica média diária. O sistema PVT além de proporcionar um aumento de energia elétrica, ainda fornece energia térmica com uma eficiência superior à elétrica. A água aquecida pode ser utilizada para alimentar sistemas de aquecimento de água para banho, contribuindo para redução do consumo de energia elétrica de uma residência.Research, Society and Development2021-06-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1615610.33448/rsd-v10i7.16156Research, Society and Development; Vol. 10 No. 7; e1210716156Research, Society and Development; Vol. 10 Núm. 7; e1210716156Research, Society and Development; v. 10 n. 7; e12107161562525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/16156/14479Copyright (c) 2021 Ramon Rudá Brito Medeiros; Arthur Vila Nova Albuquerque Lima; Gutembergy Ferreira Diniz; Vinicius Mafra Melo; Luiz Guilherme Meira de Souza; Kelly Cristiane Gomes da Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessMedeiros, Ramon Rudá BritoLima, Arthur Vila Nova AlbuquerqueDiniz, Gutembergy FerreiraMelo, Vinicius MafraSouza, Luiz Guilherme Meira deSilva, Kelly Cristiane Gomes da2021-07-18T21:07:03Zoai:ojs.pkp.sfu.ca:article/16156Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:36:47.386587Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
