Scania is putting together a trailer covered in solar cells and using that energy to power a plug-in hybrid truck. Like a previous collaboration, Scania will be working with Ernst Express again with this new venture. The 18-meter trailer will be covered in a total area of 140 square meters of solar cells. These cells will be along the top and sides of the trailer, covering the majority of available space. New sources of energy for big trucks can help save on fuel and put out fewer emissions into our air. Click the link below to learn more about this project.
