Acesso em:.https://repositorio.ufpa.br/handle/2011/10452With the increasing demand for electricity worldwide, renewable energy sources are increasingly acquiring space in the world’s energy matrix. In this context, photovoltaic energy has stood out with high growth rates. However, it is necessary to have means to evaluate the performance of the photovoltaic modules. This can be done by means of its characteristic I-V curve, from which the module’s electrical parameters can be evaluated and used as an indicator of possible manufacturing faults, connection or shading. The use of solar simulators is a faster and more reliable to obtain such I-V curve. However, the high costs of a simulator limits access to such measurement, moreover, it is limited to measure only a single PV module. This work seeks to evaluate a methodology for the I-V curve acquisition under outdoor conditions by using two capacitive loads and a reference module as irradiance and temperature sensor. The standard test conditions are obtained by means of IEC 60891 procedures. Silicon technology modules were tested and their results were compared with indoor measurement, using the solar simulator located at GEDAE/UFPA solar laboratory. The results indicated that, depending on which calculation method and considerations related to temperature, this can be a suitable methodology for the measurement of a photovoltaic module.Acesso AbertoMedição a sol-realSimulador solarExtrapolação de curva I-VOutdoor measurementSolar simulatorI-V curve extrapolationDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::SISTEMAS ELETRICOS DE POTENCIA::MEDICAO, CONTROLE, CORRECAO E PROTECAO DE SISTEMAS ELETRICOS DE POTENCIASISTEMAS DE POTÊNCIASISTEMAS DE ENERGIA ELÉTRICA
