This study aimed to analyze the accuracy of daily series of global solar radiation, simulated by the weather generator PGECLIMA_R, in the State of Parana, Brazil. For this purpose, there were used historical series of 30 years from 28 different localities, spatially well distributed, so as to represent the entire State. There were five replications for each localitie, allowing to compare the monthly average observed and simulated data to test the accuracy of the generator PGECLIMA_R through statistical analysis of the coefficients of Pearson correlation index ";;r";;, Willmott agreement index ";;d";;, confidence index ";;c";;, the mean bias error (MBE), the root mean square error (RMSE) and the mean absolute error (MAE). The comparison between data generated by PGECLIMA_R and historical data demonstrated a very satisfactory performance of this weather generator for estimating global solar radiation in almost all studied localities.
