Surrounding the main feature of the EXPO 2020, the Sustainability Pavilion are 18 E-Trees, or Energy Trees. These trees harness the energy of the sun using solar photovoltaic panels placed on the branches. The trees vary in height, reaching up to 15m high. The tree top PV panels are inclined and adjust to the position of the sun, always facing it, to maximize their energy production. Waagner Biro designed and built the trees and their hubs, including the gear box and transition between both elements.
