ABSTRACT
The subject of this paper is to present a methodology and a decision-making software tool, integrated into a Geographic Information System (GIS), that brings out the all-important role of geographic location and distribution of households in the choice of electrification systems, in particular that of photovoltaics, for Decentralised Rural Electrification. The methodology and the tool can be discribed in three steps: 1. acquisition and extraction of households location from different graphical data sources (maps, satellite pictures, etc.), 2. the taking into account of the households' spatial distribution and creation of homogeneous « density zones ». 3. comparison cost of three electrification solutions for each « density zone » created: Solar Home Systems, generator set connected to a local grid, connection to the national grid.
