Selective Allocation of Distributed Photovoltaic Systems Using Experimental Data from Tropical Areas

In this study, the solar irradiance of four different localities in the Far North province of Cameroon was assessed with a view to selecting a site for a large-scale photovoltaic array. The global radiation extrapolation method is used to evaluate the solar potential in the four localities. To verify the reliability of the chosen method, the coefficient of determination is calculated to estimate the difference between the real-time experimental method and the theoretical method based on the statistical test. So, the Root Mean Square Error, the Mean Absolute Relative Error and the Coefficient of determination are calculated, in order to make a conjecture on the performance of the proposed method. The localities of Muidere, Bougaye, Youaye and Hoyo were chosen on the basis of the availability of sunlight in these areas. The results obtained also demonstrate the feasibility of implementing the system, taking into account the real data extracted from the site.
