Abstract
Accessing subsequent use of energy is a keyαα to prosperity and sovereignty. Energy system needs to be transformed from fossil-fuels to renewable energy efficient technologies. It is vital to harness the highest possible amount of solar energy due to long sunshine hours and high insulation levels in Pakistan. The study aims to identify potential sites for solar energy in Gilgit Baltistan Pakistan using Geographical Information System and Analytical Hierarchy process. Three main factors Environmental (distance from residential areas and land use), Economic (aspect, slope, and proximity to transmission lines and roads) and Physical (solar irradiance) were considered and weights were assigned to these factors based on their relative importance. The results reveal that Gilgit Baltistan has potential for solar power development as it receives solar radiation greater than 4 kWh/m2/day from April to September. Land suitability analysis has revealed that 10% (6706 km2) and 9% (5590.08 km2) of the area are very highly suitable for harnessing solar potential sites in Gilgit Baltistan using Pakistan Meteorological Department data and National Renewable Energy Laboratory solar data respectively. While District Diamir has 15% and 13%, Gilgit has 14% and 13%) and Ghizer has 11% and 12% potential for Photo Voltaic solar power systems installation based on both Pakistan Meteorological Department and National Renewable Energy Laboratory solar data. This study supports the decision makers and investors to look into the possibility for installation of Photo Voltaic solar energy systems.
