A solar tree is a structure that uses solar panels arranged like a tree to generate renewable energy and electricity. It has multiple solar panels mounted on a tall pole to maximize energy production using minimal land. The panels convert sunlight into electrical energy through the photovoltaic effect. Solar trees have applications for street lighting, domestic and industrial power supply, and can help rural areas gain electricity access in an eco-friendly and renewable way. While their installation has high initial costs, solar trees provide environmental and economic benefits over traditional solar power systems.
