In this comprehensive guide, we explore how geography, climate, and technology influence solar energy generation, and how you can estimate the solar potential in your area. With energy prices rising and power reliability becoming increasingly uncertain, understanding your local solar potential is more valuable than ever. The truth is, almost every region receives some degree of sunlight year-round—but how much you can harvest depends on where you live and how you. Explore solar resource data via our online geospatial tools and downloadable maps and data sets. Access our tools to explore solar geospatial data for the contiguous United States and several international regions and countries. However a generic solar resource map may not show the complete picture. In the Regional Solar Energy Potential Study, we analyze not only solar. Welcome to Global Solar Atlas v2. Select sites, draw rectangles or polygons by clicking the respective map controls. Ranking 2nd in the nation, Texas has 48. 2 GW installed and is expected to continue to grow. Solar energy development has been concentrated in the Atlantic and West regions of the United States, especially in California, North Carolina, and Massachusetts.
