“…These include the model proposed by Rietveld [28] relating a and b to n=N, and the one proposed by Glover and McCullogh [21] relating a to latitude. The former is widely misinterpreted [17] and the latter is rated poorly [36][37][38]. To our knowledge, no one has ever used Z or P alone in the parameter model, but according to our results, they could be used with confidence.…”

The main objective of this research is to analyze the monthly average daily of global (H), beams (B) and diffuses (D) solar irradiance on a horizontal surface at four selected sites (El-Kharga, Hurghada in Egypt and Dammam, Hail in Saudi Arabia) during the period time from 1980 to 2020. The empirical models between (H/H o ) and meteorological parameters along with the values of (MBE), (RMSE), MPE, R 2 and the t-Test statics are discussed. The results in this study indicate good agreement between observed and calculated values of total solar energy and diffuse solar fraction. The results for south facing surfaces of the (RMSE) for different slope at different models in the present research are discussions. Nine different models between isotropic and anisotropic used to estimate the diffuse solar radiation on a tilted surface at selected sites in this study. The absolute relative values of RMSE for the southfacing surface ranges from 7 to 41.3 at El-Kharga and Hurghada sites, Egypt in the present study for Koronakis and Stevenand Unsworth (SU) models respectively. The values of (RMSE), for the south-facing surface ranges from 9.3 to 39.7 at Dammam and Hail sites, Saudi Arabia in the present research for Koronakis and Klucher models respectively. For west-facing surface the values of RMSE range from 11.2 to 47.3 for Badescu and Koronakis models at El-Kharga and Hurghada sites, Egypt respectively, while values of RMSE range from 6.5 to 38.5 for Klucher and Reindl et al. models at Dammam and Hail sites, Saudi Arabia. The models Koronakis, Klucher and Stevenand Unsworth (SU) models are given the most accurate estimate for the south-facing surface, and Badescu, Koronakis, Klucher and Reindl et al. models are good performs better estimated for the west-facing surface.

“…The mathematical models of regression AutoRegressive (AR), Moving Average (MA) and AutoRegressive Moving Average (ARMA) are among the more used. These models are in general developed using the Second Order Statistics (SOS) or the High Order Statistics (HOS) techniques mainly applicable for stationary processes [1][2][3][4][5][6].…”

The main goal of this investigation is to use the fuzzy systems of Takagi Sugeno (TS) for modelling the daily solar radiation data. The Takagi-Sugeno models are a non-linear techniques, defined by a set of If- Then rules, each of which establishes a local linear input-output relationship between the variables of the model. The TS fuzzy model is trained using data of daily solar radiation recorded on a horizontal surface in Dakhla in Morocco. The predicting results indicate that the Takagi-Sugeno fuzzy model gives a good accuracy of approximately 96 % and a root mean square error lower than 6 %. In addition, the performances of the identified TS fuzzy model are then compared to a linear model using the SOS techniques. The results show the effectiveness of the non linear model.
