Solar energy, 2011•ElsevierIn this work, a new approach that contains two phases is used to predict the hourly solar
radiation series. In the detrending phase, several models are applied to remove the non-
stationary trend lying in the solar radiation series. To judge the goodness of different
detrending models, the Augmented Dickey–Fuller method is applied to test the stationarity of
the residual. The optimal model is used to detrend the solar radiation series. In the

In this work, a new approach that contains two phases is used to predict the hourly solar radiation series. In the detrending phase, several models are applied to remove the non-stationary trend lying in the solar radiation series. To judge the goodness of different detrending models, the Augmented Dickey–Fuller method is applied to test the stationarity of the residual. The optimal model is used to detrend the solar radiation series. In the prediction phase, the Autoregressive and Moving Average (ARMA) model is used to predict the stationary residual series. Furthermore, the controversial Time Delay Neural Network (TDNN) is applied to do the prediction. Because ARMA and TDNN have their own strength respectively, a novel hybrid model that combines both the ARMA and TDNN, is applied to produce better prediction. The simulation result shows that this hybrid model can take the advantages of both ARMA and TDNN and give excellent result.
