ABSTRACT
Global and diffuse solar radiation studies have been carried out for upper Sindh (Jacobabad) to assess the applicability of solar energy utilization for these areas. The global and diffuse solar radiation was carried out using sunshine hour data. The result obtained shows the variation of direct and diffuse component of solar radiation in summer and winter months. In Jacobabad areas the diffuse radiations is maximum during the month of July and August and minimum during the months of November, December and January. The cloudiness index KT values indicate the clear sky in the month of January to June and September to December for Jacobabad. From the studies it has been found that with the exception of monsoon months July and August solar energy can be utilized throughout the year for Jacobabad.
