A solar tree is a structure incorporating solar energy technology on a single pillar, like a tree trunk. It may be a soalr art work or a functional power generator.
Solar trees are intended to bring visibility to solar technology and to enhance the landscape and architecture they complement, usually in a commercial or public context. An objective of many solar tree installations is to promote awareness, understanding, and adoption of renewable energy. They are not typically used as a primary source of energy for a property—that role is accomplished by rooftop solar systems. Solar trees are complementary to rooftop solar systems, or other green building measures, symbolizing these larger investments and their environmental benefit.
Solar trees may build awareness and interest in solar technology and also provide shade and meeting places.
