Solar energy potential assessment at four typical locations in Ethiopia
(English)In: Energy for Sustainable DevelopmentArticle in journal (Refereed) Submitted
As a continuation of the study into wind energy potential previously completed, solar energy potential at the same four locations in Ethiopia has been investigated. These are Addis Ababa, 09” 02’N, 38” 42’E, 2408 m (AMSL); Mekele, 13” 33’N, 39” 30’E, 2130 m; Nazret 08:32N, 39:22E, 1690 m; and Debrezeit, 08”44’N, 39” 02’E 1850 m. As in the case of the wind data no radiation data has been properly recorded to evaluate the sola renergy potential of the country, except for in one single location, Addis Ababa. However, sunshine duration data has been collected over a relatively long period of time. Therefore, this study is based on sunshine duration data collected over more than 10 years at the specified locations and also on software and satellite interpolated data obtained from sources outside the country. A thorough literature survey has been carried out and different models by different authors have been investigated. After analyzing the data using well known equations taken from standard text books, the results obtained are given in the form of solar radiation plots for all locations. This study is the second stage in the assessment of the feasibility of a hybrid standalone electricity supply system to remotely located communities detached from the main grid.
