Frequently Asked Questions

The Sion is an innovative vehicle that additionally charges its battery using energy from the sun. In the course of series development, the solar integration was further optimized by our team of experts. Solar cells integrated into the body make it possible to use the Sion for several days without having to recharge it.

A total of 456 half cells can generate up to 1.2 kilowatts at peak power. This energy can generate power for 112 km on average (up to 245 km) of additional driving range per week. In a year, that's on average 5,800 kilometers of emission- and cost-free range. Solar integration allows you to cover a large percentage of your average daily mileage using solar energy alone. For the solar cells, we use monocrystalline silicon cells that are integrated into the vehicle's body. Selecting the right material is our top priority. The components used must meet the following requirements: A service life of at least eight years, resistance to environmental influences such as UV rays and water, break resistance and a low weight. Usually, solar cells are laminated onto a 2 - 5 mm thick glass. However, glass has a comparatively high weight and only low break resistance. We therefore use polymer as substrate material. It is light, resistant and significantly more break-proof than glass.

If you experience a minor collision, you should first of all check to see whether and to what extent the cells in the affected panel are damaged. There is a layer of polymer that provides the solar cells underneath with the best possible protection against impact and damage, such as scratches. Unlike glass, polymer is shatterproof and makes our solar modules significantly more durable than traditional panels. Therefore, you should check the damaged module to see if it is still functioning and only replace it if it is genuinely in need of replacement.

The solar cells integrated into the body of the Sion can add up to 245 km (112 km on average) of driving range per week through solar energy to the car’s battery. In order to make the most efficient use of sunshine hours throughout the day, charging via solar integration will be possible whilst driving.
