- Wavelets widely applied in filtering the data and help to forecast in many separate fields. In this study, Daubechies Wavelet was used to study hourly solar radiation in Baku city, Azerbaijan. The results demonstrated that timing of global radiation changes have a periodical and non-linear nature. Apparently, the level 5 is sufficient enough, despite the fact that wavelet was extended to level 12 originally. Analysis presented that original series interval is 4 and series stayed unchanged. Also, it was indicated that the original signal is restored on the basis of wavelet factor d1-d5, trends should first be removed from the original series.
