The Potential of Hybrid Solar-Wind Electricity Generation in Ghana

Abstract

In this work the potential of harnessing electricity from solar and wind sources in Ghana is evaluated both quantitatively and qualitatively. In this regard solar, wind and other relevant data were collected (over a period of one year) from various parts of Ghana. Detailed assessment of the capacity or potential of power production from hybrid solar-wind sources is done with the use of empirical mathematical formulae and the PRO VITUS model incorporated in the ̳ENERGY X‘ software. The various characteristics of wind, solar and available energy resources for the five locations over a one year period have been studied too. The annual mean wind speed at a height of 10 m above ground level for five locations namely Accra, Kumasi, Takoradi, Sunyani and Tamale are 2.38 ms -1 1 2.18 ms -1 and 2.47 solar radiations are 228.71 Wm -2 Wm -2 and 231.63 Wm -2 , 2.39 ms -1 , 2.38 ms - ms -1 respectively and their corresponding annual mean 187.69 Wm -2 236.58 Wm -2 200.99 . Thus, the five sites hold potential for hybrid solar-wind energy exploitation.
