Direct solar radiation measured with a pyrheliometer installed at the meteorological station of Sidi Bou Said (Northern Tunisia) is used to investigate the atmospheric turbidity using Linke's factor. The obtained results indicate high variability of the diurnal and seasonal components of...

The solar systems technology offers a promising method for the large scale use of solar energy in the southern zone of Algeria. The magnitude of solar radiation is the most important parameter for sizing these systems. The chief goal of this investigation is to contribute to the national efforts...
