The product is made of concrete, teak wood, and stainless steel. The energy is provided entirely by mono-crystalline solar cells. These are located 3 meters above ground for less shading and on a 30° angle for a higher efficiency. They are also set on security glass allowing people to immediately recognize their presence.
The energy bank is either a simple battery system or a grid-tied system located under the seat.
For easy use and direction there is a green light layer on the top that shows from a distance when there is energy available in the system, as well as providing dim lighting to the closer area.
