This document describes a project that used GIS to map and compare the solar energy potential of Kenya and Pakistan. The objectives were to map the main factors influencing solar energy generation in both countries, reclassify these factors by their influence on potential, and combine the factors to map overall potential. Data on solar radiation, cloud cover, accessibility, land cover and other factors were analyzed for each country. The factors were reclassified and weighted overlay was used to create potential maps. Results showed that 72% of Kenyan land and 50% of Pakistani land had high potential, though clouds and snow in Pakistan's Himalayas limited potential there relative to Kenya.
