Abstract
The present work consists of designing and performing an experimental analysis of a photovoltaic (PV) system with solar tracking mirrors for taking advantage of the direct and diffuse solar radiation. The solar system is installed in the northwest region of the state of São Paulo. V-trough photovoltaic (PV) concentrator systems are designed to increase solar input to photovoltaic cells but an increase in the cell temperature can occur by increasing the incidence of solar radiation on the photovoltaic assembly. The study aims to analyze the temperature distribution and the occurrence of hot spots - points with temperature higher than the Nominal Operation Cell Temperature (NOCT) - in the photovoltaic panel caused by the effect of the solar concentration. The analysis takes into account the temperature in the photovoltaic cells, the local meteorological data and also the voltage and current generated by the PV system. Based on the results and analysis, it will be possible to verify if this V-trough photovoltaic (PV) concentrator system reduces the useful life of a commercial PV module, and to develop new technologies for an optimized use of solar energy by using low-cost devices.
