Solar Trees are made of a metal structure and have solar panels at the top instead of branches of real tree. Solar energy is collected by Solar panel and converts it into electricity and uses it for batteries, charging of mobile phones, portable computers and tablets. The panels and lighting use this collected energy.
Developed by MIT engineers, SolarSkin is a thin film specially coated with ultra-durable graphics and integrated onto high efficiency solar panels. The technology employs selective light filtration to simultaneously display an image and transmit sunlight to the underlying solar cells with minimal loss in efficiency.
