Abstract

Information on the availability of global solar radiation of a given geographical location is an essential factor in developing suitable solar energy system and devices for various applications. In this project, data for daily relative humidity, maximum and minimum temperatures were used to estimate mean global solar radiation in Gusau city, Nigeria. The daily relative humidity, maximum and minimum temperature were measured for period of 6 years (2015 - 2020) from which the monthly mean values were determined. Angstrom-Prescott model was then used to estimate the global solar radiation based on the monthly mean sunshine hours. The values of global solar radiation for Gusau ranged from 16.1676 - 21.6536 MJm-2day-1 under the period of study with mean value of 18.8015 MJm-2day-1. These values can be utilized in the design and performance of solar energy systems in Gusau.
