Abstract

The purpose of the present work was to develop the study of an autonomous photovoltaic system, with storage of energy, installed in the Agro-meteorological Experimental Station of Universidade Estadual do Oeste do Paraná, State of Paraná, Campus Cascavel, at 24º 59´ latitude south, 53º26 longitude west, 682 meters of altitude, under real field conditions, during the year 2002. Efficacy of the photovoltaic panels has been evaluated under real field conditions, as well as to determine its characteristic linear fit. A 'micrologger' Campbell Scientific-INC model CR10X was used to acquire data, and it was programmed to accomplish a reading per second in each channel and to store the arithmetic average of data from five minutes of operational temperature of the panel, photovoltaic system tension and current. According to results, it could determined that the panel characteristic linear fit in real field conditions shows 24% less field than standard STC (Standard Test Conditions)
