This document discusses solar trees, which are decorative structures that produce solar energy. A solar tree uses multiple solar panels arranged in the shape of a tree to generate renewable electricity. It has components like solar panels, a long tower, batteries, and stems connecting the panels. The panels are arranged in a spiralling phyllotaxy pattern to ensure each cell receives equal sunlight, increasing efficiency. Solar trees have advantages like producing energy with less land use and no air pollution, but disadvantages include high costs and potential hazards to wildlife. They can power applications like street lights, homes, industries, and electric vehicle charging.
