Predicted and Measured Global Solar Radiation in Maiduguri, Nigeria
Subject area: Science,Engineering and Technology · Area of research: Applied Physics
Abstract
A model for estimating sunshine hours from some meteorological parameters was developed. Ten years (2001 ? 2010) period of Sunshine hour and Solar radiation at Maiduguri, Nigeria (11.85o N, longitude is 13.08?E) was analyzed. A correlation equation of the Angstrom type was developed to predict the monthly mean daily global solar radiation incident on a horizontal surface in Maiduguri, Nigeria: H ?_m/H ?_o = 0.34+0.42S ?/S ?_o . Thestatistical error estimations such as RMSE, MPE and MBE used to test the correlation between the measured global solar radiation and the calculated global solar radiation. The RMSE was found to be 0.05 as low as expected, the MBE was also found to be 0.015 and MPE to be 0.062 values are low. The developed model can be used in estimating global solar radiation for Maiduguri and other locations with similar climatic conditions.
