Abstract
The aim of this work was realized an energy balanced, using collected parameters in an experimental project and perform an electrical and thermal analysis of a photovoltaic panel. Developed a photovoltaic panel, through the manufacture of its components, being installed thermocouples behind the solar cells and on top of the glass to determine respectively the temperature in the cells and the temperature on the surface. The other data were made through the compact meteorological station and two pyranometers that measured the ambient temperature, wind speed, the horizontal global radiation and the global tilted radiation with an inclination equal to latitude in Brasília-DF. To register the voltage data used if an open circuit system connected directly in the Datalogger. The efficiency of a photovoltaic panel is influenced by solar radiation and temperature. Therefore, it is important to perform analysis of the energy balance to cover all its components. It was possible to verify the temperature variations in the cell through three different methods: collected by the experimental apparatus, calculated by the mathematical model and calculated by Kalogirou (2016). The results showed a great approximation with the Kalogirou equations. The methodology is based on data collection in an experimental project and analysis will be developed through the software MATLAB® R2016a.
