An eco-friendly and low-cost electric car with integrated photovoltaic cells

July 2018
Gallery Sion 1
Gallery Sion 1


With 248 separate solar cells integrated into the chassis of the car, the Sion can charge itself for up to 34km a day in European weather conditions – enough for city commuters.

The Sion aims to make electric mobility more affordable and available for a much lower cost and in a market where lack of charging infrastructure and perceived limited range is deterring its uptake. Its characteristics include simple and cost-effective manufacturing by a third party, bi-directional charging (it generates and also provides energy), a range of 250 km on a full charge, and maintenance and mobility services. Furthermore it is shatterproof, light and particularly weather resistant thanks to a polycarbonate layer on the solar cells.
