The document discusses the growth of solar power capacity in Germany, particularly from small-scale, citizen-led projects. It notes that solar capacity has grown fastest in rural communities with strong social networks, where people team up to build solar projects that benefit the community. While most solar capacity is currently in rural areas, there is untapped potential on city rooftops. The document outlines a model for citizen-led solar projects, involving initiation, planning, funding, and management. It also describes support resources and networks that have helped propagate this community solar model across Germany.
