===Geographical potential using GIS===
In order to assess
various aspects of the PV system implementation, a geographical representation of the variables is necessary. Local level spatial disparities are necessary to assess to find places lacking infrastructure and technology for broadband access (Grubesic and Murray 2001).
Among the geo-processing capabilities of GIS perhaps the most useful is the overlay function. GIS has shown its usefulness in rural and urban planning, sustainable development, and identifying site specific locations
(Refs). The different layers, including electric networks, broadband networks, and population density , can be synced to identify rural locations for technology dissemination. The geographical information system (GIS), ArcGIS, was used to organize spatial variables to find cells, of resolution 1 km2, that is appropriate for standalone PV system installation. We computed the locations of remote sites for SAPV installation from creating 6 layers incorporating buffers from the electric grid and broadband access at 500m, 1,000m, and >1,000m (Muselli et al. 1999). Additionally, a layer of population density is used to interpret potential market and impact.
