Estimation of the Global Solar Radiation in Okura Kogi State Using Angstrom-Prescott Model

Abstract

This research is aimed at estimating Global Solar radiation data in Okura Kogi State using the sunshine hour data obtained from Anyigba. Angstrom Prescott model was used to estimate the global solar radiation for Anyigba using the latitude of the area which is 7.4809 and the sunshine hour, after the which the Global Solar radiation data in Okura, Kogi State (Latitude 7.4146) was estimated The Angstrom Prescott model for Okura was found to be = (0.2325+0.6655(S/s0). Where the regression coefficient a and b were found to be 0.2325 and 0.6655 respectively. The result was validated using a 6years global solar radiation data between years 2011 to 2016.
