Like the Netherlands based Lightyear solar car start-up, Germany based solar electric car start-up, Sono Motors GmbH is also looking to change e-mobility with the use of solar cells on its self-charging solar electric vehicle (SEV), called the Sion

The company was founded in 2016 by Jona Christians and Laurin Hahn with a vision to realise a future free of fossil fuels, with only electric and shared transportation.  Between 2016 and 2017, the Munich based company conducted crowdfunding campaigns and raised EUR 2 million.  It has come a long way since then, and in January 2020, the start-up raised EUR 50 million in 50 days.

  • The all-electric front-wheel drive car is equipped with 248 integrated solar cells (monocrystalline silicon cells).  These cells are placed on the hood, fender, sides, roof and rear of the vehicle. At peak performance, the solar cells can generate up to 1.2 kilowatts.  The solar cells are protected by a robust, scratch-resistant polymer. 
  • The solar electric car has a 35 kWh lithium-ion EV battery.  The battery will be available to rent, lease or outright purchase.

  • Features will include, anti-lock braking system, ESP with traction control, electronic power steering, infotainment system with integrated connectivity and mobility services/ goSono systems (powerSharing, rideSharing, carSharing).
  • The EV will come with a standard warranty of 2 years or 100,000 kms.
  • The solar electric car will be manufactured in Europe (Sweden) using 100% renewable energy.  Total number of Sion SEVs to be manufactured are 257,000.   So far the solar electric vehicle manufacturer claims to have received 13,000 pre-orders. Production will commence second half 2021.
