Through the Solar Energy Evolution and Diffusion Studies (SEEDS) Funding Opportunity Announcement (FOA), the Department of Energy will invest up to $9 million over three years to support research on solar energy innovation dynamics and technology adoption patterns. SEEDS supports the development of a diversity of analytical, numerical, and conceptual tools and methods; implementation of pilot test strategies for modifying current business and policy practices; and assessment of pilot tests outcomes for impact and scalability. Through SEEDS, the Department of Energy seeks to launch a series of systematic investigations that will result in viable methods for dramatically transforming the operations of solar researchers, manufacturers, developers, installers, and policymakers. Selected research efforts will be performed in tandem with industry partners to ensure that results can be applied, tested, and modified in real time.
