Photovoltaic systems make solar energy an alternative energy source for some landscape design applications. The most notable of these applications are in landscape lighting, and the most efficient are in remote areas where they are also most cost-efficient. Site-specific design of these systems requires a technical understanding of their components, along with typical siting issues of sun angles and shading from trees. The expertise of landscape architects in addressing these site issues makes it possible for more progressive professionals to take on the lead role in designing solar-powered landscapes
