Fifty-four broadband clear-sky models for computation of global solar irradiance on horizontal surfaces are tested by using measured data from Romania (South-Eastern Europe). The input data to the models consist of surface meteorological data, column integrated data and data derived from satellite measurements. The testing procedure is performed in twenty-one steps for two different sites in Romania. The models accuracy is reported for various sets of input data. No model ranked %26quot;the best%26quot; for all sets of input data. However, some of the models were ranked among the best for most of the testing steps, and thus performed significantly better than others. These %26quot;better%26quot; models are, on an equal footing, ESRA3, Ineichen, METSTAT and REST2 (version 8.1). The next %26quot;better%26quot; models are, on an equal footing, Bird, CEM and Paulescu and Schlett. Details about the accuracy of each model are found in the Electronic Supplementary Content for all testing steps.
