Abstract
The photovoltaic (PV) module operating temperature influences its electrical efficiency, a fundamental parameter for PV power forecasting. The present research is divided into two stages and aims to use some classic models, based on the temporal analysis of the data, applying them to the meteorological conditions of Fortaleza, Ceará, to predict the PV module operating temperature in a real arrangement. Initially, our study uses the programming language R to build linear regression plots based on the data. In the second step, the R programming language is used to estimate possible operating temperature values of the PV module based on the input data: solar irradiation, wind speed, ambient temperature and the PV module structure material. The influence of wind speed on the PV plant is analyzed, as it acts as a natural cooler for PV cells. It is important to note that both the position of the PV modules in relation to the wind and the magnitude of the wind speed influence the operating temperature. The models are tested with data from the Alternative Energies Laboratory of the Federal University of Ceará (LEA - UFC), checking for each model which are the predictors and the operating temperature of the PV module, as each model has an application depending on humidity, irradiation, magnitude of wind speed and PV module material. Based on the models results, a graphical analysis is proposed in order to compare their performance and improve the algorithm in R, so that the PV module operating temperature value can be more quickly and objectively applied.
