Analysis of Solar Energy Potential Using Sunshine Based Model

Abstract

Solar photovoltaics are in recent times being used to replace fuel-based lighting and off-grid electrical needs. This study presents the evaluation of solar photovoltaic power systems in Dirashe Woreda of Ethiopia. The study was performed to assess and analysis the data which were acquired from the selected site. A descriptive survey was used to assess the information gathered. Empirical models were used to forecast the radiation based on sunshine hours. The linear monthly average solar radiation of the study site was calculated using data from the National Aeronautics and Space Administration (NASA). The study also includes an estimate of the study area’s solar energy resource based on primary data collected between January and December 2019. Finally, an equation using Angstrom-Prescott Model was derived for the study area.
