GIS-based photovoltaic solar farms site selection using ELECTRE-TRI: Evaluating the case for Torre Pacheco, Murcia, Southeast of Spain

The GIS provides a cartographic and alphanumeric database, including two factors of distinct nature: restrictions and criteria. The restrictions are entered into the GIS using layers defined from the current legislation (urban land, undeveloped land, special protection areas for birds, community sites, infrastructures, etc.), which reduce the study area by eliminating those areas in which photovoltaic solar farms cannot be implemented. The criteria are organized into a tree to be used for assessing the greater or lesser capacity to install photovoltaic solar farms. These criteria are introduced into the GIS, taking into account weather, environmental, location, and terrain evaluation aspects.
