Rezumat: This paper presents a taxonomy and evaluation of models for forecasting and estimation of various solar irradiation components received at ground; the aim is to compensate for the lack of measures in meteorological stations throughout the country. The chosen models have been proposed in the literature by scientists and researchers. These models are a function of the main meteorological parameters such as relative humidity, temperature, pressure, as well as geographical parameters of the site considered as longitude, latitude and altitude, they also depend to some astronomic parameters like the day number and the solar constant. Three models were studied and simulated for the aim to estimate the solar radiation components at ground level. Finally, comparisons are carried out between the obtained results through simulation and measured values actually found in some Algerian sites where such measurements are possible and available. The aim is to establish the criteria for selecting models according to the geographic and meteorological conditions. The obtained results through simulation of the three models, give good estimate of solar components where errors between the calculated values and those measured are negligible. We can say that the chosen models are good for estimation of solar radiation at ground.
