Increasing installation of grid-connected photovoltaic (PV) energy systems demand more accurate prediction of their operational performance. Argentina has prompted the research that aims to establish the relationships between output efficiencies and weather parameters. The direct use of efficiency figures quoted by PV manufacturers, normally based on measurements taken in clean laboratory environments of 25°C and at standard air density, is often not appropriate as field studies have demonstrated the actual outputs could be reduced by as much as 60% in dusty or polluted climate without regular cleaning. The experimental investigations and case study took place in the city of Mar del Plata in the southeast of Argentina. First, outdoor field measurements were taken and then a statistical evaluation of weather parameters and system outputs from the actual PV installation was produced for a whole year. The results obtained are then compared with irradiation data provided by the National Renewable Energy Laboratory (NREL) and deviations between those estimations and experimental data is presented.
