Abstract

Estimations of global solar radiation based on a model of using normalized clearness index and normalized sunshine duration for a period of up to 25 years (1985-2010) for Ikeja (06.39°N, 03.20°E), Enugu (06.280N, 07.350E), and Kano (12.03 N, 08.32E), Nigeria for each climatological stations were established. The monthly average total solar radiation was also estimated. The reliability index of the calculation varies from 2.4 to 2.6 percent. The overall results show that for Kano, the received radiation on the plane surface is higher than for Ikeja and Enugu.

Highlights

Solar radiation is the energy that comes from the sun which generate huge amount of energy through the process of nuclear fusion
The global solar radiation on horizontal surface at the location of interest is the most critical input parameter employed in the design and prediction of the performance of solar energy device. (Hussain, et al, 1999)
The accuracy of the estimated values was tested by calculating the Mean Bias Error (MBE), Root Mean Square Error (RMSE), and Mean Percentage Error (MPE)

Summary

Introduction

Solar radiation is the energy that comes from the sun which generate huge amount of energy through the process of nuclear fusion. The global solar radiation on horizontal surface at the location of interest is the most critical input parameter employed in the design and prediction of the performance of solar energy device. The solar radiation reaching the earth’s surface depends on the climatic condition of the specific site location, and this is essential for accurate prediction and design of a solar energy system (Burari and Sambo, 2001).
