Solar irradiance variability introduces limitations to photovoltaic (PV) solar energy production because it hinders energy dispatch. Therefore, their quantification is important for large-scale development of PV systems and their relative contribution to the electrical grid. Argentina has a significant potential for solar energy generation, with anextensive territory receiving an average annual irradia tion of 5 kWh/m2 /day. Furthermore, it is supported by public policies and regulations that promote the transition to renewable energy sources. This study quantified short -term variability (minute, 10-minute, and hourly) using the standard deviation of changes in the clear sky index (kc). Time series for 2019 and 2020 were analyzed at six stations from the Argentine solar radiation network Saver-Net. Average nominal variabilities of 0.09, 0.13, and 0.15 was found for 1 min, 10 min, and 1 h, respectively. These values suggest an intermediate variability in solar resources across the territory.
