Solar energy stands at the forefront of renewable energy sources, benefiting significantly from a range of federal incentives designed to accelerate its development and deployment. The support from federal programs not only enhances technological advancements but also makes solar energy more accessible and affordable for a broader spectrum of users, from individual homeowners to large industrial enterprises. The Solar Energy Technologies Office (SETO), part of the Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE), is pivotal in this transformation.
