Solar radiation prediction is a nonlinear and non-stationary process. It's hard to model with a single method. A wavelet neural network model was set in this paper. The nonlinear process of solar radiation was forecasted by neural network and the non-stationary process of solar radiation was decomposed into quasi-stationary at different frequency scales by multi-scale characteristics of wavelet transform. The model was trained with temperature, clearness index, and phase space reconstruction
