Global solar radiation is a key input to investigate power generation potential of photovoltaic plants and other solar energy applications. However, ground measurements are punctual, scarce and scattered in Argentina. For this reason, the scientific community and the solar energy devices installers mostly use statistical methods to estimate global solar radiation for a particular location. On the other hand, the accelerated development of satellites in the last decades propose satellite based radiation data as a choice to handle this lack of information. In this study, we evaluate global solar radiation from the reanalysis dataset (ERA-5) provided by the European Centre for Medium-Range Weather Forecasts (ECMWF). This data is compared with data generated using statistical methods and with data from 7 pyranometers. The study covers the province of Santiago del Estero, located in North Argentina, and considers the period of time from 2010 to 2016.
