Preliminary analysis of ground based measured solar data from sauran sta station at Umlazi, South Africa

This paper presents the preliminary analysis of ground-based measurements solar data in Umlazi, South Africa. From this analysis, data statistics and statistic models for the global horizontal irradiance (GHI), the direct horizontal irradiance (DHI) and the ultraviolet radiations (UVR) are obtained for Durban and surrounding areas. Those results can be used in the design and analysis of solar systems and can also be used as referential parameters for further assessment of solar energy potentials for those areas.
