Areas in Tibet have some of the world’s highest photovoltaic energy potential due to high altitude and low temperatures. High altitude correlates with high solar irradiation and low temperatures increase the efficiency of photovoltaic elements. We performed a GIS Boolean sieve-mapping analysis based on elevation, slope, aspect, protected areas and land cover to determine suitable areas for large-scale solar power production. Our analysis revealed that suitable areas are mostly small (less than 1 km^2) and scattered and only constitue a total of 36 km^2, which is far below the 12000 km^2 necessary to power all of China. However, altering different aspects of the analysis and including higher resolution datasets might increase the amount of suitable area.
