Photovoltaic Water Pumping System Site Suitability Analysis Using AHP GIS method In Southern Algeria

Abstract

This paper presents an application of geographic information system (GIS) combined with AHP (Analytic hierarchy process) approach in remote area, for mapping suitable areas for PV pumping ( the photovoltaic) plants in Ghardaïa region –southern of Algeria. In order to select a different site suitable for the application, we use often Multi criteria evaluation methods, seven defined criteria have been analyzed, including solar radiation, altitude, water’s areas, waters lines, population vegetal cover, distance from roads and ground water. The analytic hierarchy process (AHP) approach is mostly used to determine the normalized Weight in order that to establish their importance in the selection site. A siting suitability map was generated to identify those areas that are most suitable for solar PV pumping plant.
