Abstract

This study focused on the measurement of global solar radiation at the Presco Campus of Ebonyi State University, Abakaliki-Nigeria (06°N, 08°E, 43.9 m) in the month of September, 2015. The variability in global solar radiation was measured using a daystar meter on 30 min, hourly, daily, weekly and monthly scales. GPS global positioning instrument No. 13467763 was also used in determining the elevation and position of the area where the experiment was carried out. The results showed that the peak of the hourly average global insolation was 2.25 W/m2. In a clear partially bright sunny day, the daily average of global solar radiation was 627.44 W/m2 while the daily average of irradiation on a cloudy day was 384.19 W/m2. On a weekly scale, the average irradiation was 2.95 W/m2 whereas on a monthly scale, the average was 11.79 KW/m2 for the month of September, 2015.
