The meteorological condition and in the tendency to underestimate the radiation absorption by cloud cover. Regression and MOS techniques, such as Mosrh [3], improve the forecast of solar radiation, although they need historical set of measurements of solar radiation for the prediction site. Satellite short wave radiation data, if used as reference historical data, can be a valid alternative for the application of MOS techniques.Furthermore, an ensemble of regression formulas, with satellite data as reference historical data, can give an additional improvement of the quality of the forecast.
