With ample land, strong solar potential, and new federal funding streams, rural solar development is on the rise. From farms to fairgrounds, small towns to tribal lands, solar is becoming a critical tool for resilience, economic growth, and local energy independence. . Energy poverty is a pressing issue in rural communities, where grid infrastructure may be limited or non-existent. Solar power offers a viable solution by harnessing the abundant energy from the sun. These challenges include the lack of grid. . Alternative energy sources such as wind, geothermal, hydro and solar have grown increasingly popular as ways to reduce greenhouse gas emissions and strengthen the grid by decentralizing power production. In Sub-Saharan Africa, for instance, an estimated 600 million people do not have electricity.
