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.
Highlights
The global solar radiation is of economic importance as renewable energy alternatives and this has made the study of solar radiation and its measurement very paramount in physics and science in general
Solar radiation is the total frequency spectrum of electromagnetic radiation produced by the sun
The measurement was taken in 30 min interval from 6.00 am to 6.00 pm for the duration of four weeks in September 2015, starting from Monday to Sunday respectively in each week
Summary
The global solar radiation is of economic importance as renewable energy alternatives and this has made the study of solar radiation and its measurement very paramount in physics and science in general. Radiation is the transmission of energy through space. The radiation transmitted consists of particles or waves. Solar radiation is the total frequency spectrum of electromagnetic radiation produced by the sun. This radiation can be in form of direct and diffuse radiation. Several fusion reactions have been suggested to supply the energy radiated by the sun of which the most important is the combination of four proteins to form helium nucleus (Tiwari, 2006)
