Estimation of global solar radiation in the Indonesian climatic region

摘要

In this paper the monthly average daily global solar radiation correlation applicable to the Indonesian climatic region is presented. The correlation developed is based on the meteorologi- Cal data collected from seven meteorological stations, namely: Banjarbaru, Denpasar, Jakarta, Kupang, Manado, Palembang and Semarang. The correlation developed evolves from the Sayigh's "Universal Formula" with a slight modification in the form of a correction factor (I_CF) to suit the Indonesian climatic conditions.
