The document describes a solar tree, which is a structure that uses multiple solar panels arranged like a tree to generate solar energy efficiently in a small space. A solar tree functions like an actual tree, with solar panels as leaves that convert sunlight into electricity. It provides several advantages over traditional solar panel installations by taking up less land area while generating the same or higher amounts of power. The document also discusses the history of solar energy technology, parts of a solar tree, applications, and advantages and disadvantages of the solar tree design.
