Solar Integration in Vehicles

Reduce fuel consumption, become less dependent on the power grid and save CO2-emissions.

Your Potential Energy Savings

In the coming years, energy prices will only rise. Reach out to us to learn how you can save energy with our solar technology. Here are a few use cases with calculations based on best meteorological conditions in our homebase Munich, Germany.


Solar integration for a 12-meter bus to feed energy into auxiliary systems, e.g. HVAC or as a range extender for e-buses*. Solar integration on half of the roof and sides covering a diesel bus:

  • up to 100% of the energy demand covered by solar
  • up to 70% energy cost savings compared to diesel engine

Trailers & Trucks

Solar integration for large trailers of 13+ meters to feed energy to a refrigeration system or as a range extender for e-trucks*. Solar integration on roof and sides for a reefer truck:

  • up to 100% of the energy demand** covered by solar
  • up to 80% energy cost savings compared to diesel engine

Light Electric Vehicles

Solar integration for light electric vehicles to extend range. Solar integration on the roof and sides of vehicles:

  • up to 45 km per day of additional range
  • potential independence from charging infrastructure***
  • up to 43 % energy cost savings compared to the power grid
*Solar modules can be integrated into electric and diesel vehicles. Not all possible use cases are shown here.
**Energy demand defines the energy [kWh] needed to run the refrigeration unit of the truck for one day. With the peak conditions we can reach up to 100% of this energy demand. The yearly average of energy earnings is approx 50% of the energy demand.
***This is based on a daily mileage of 25 km for light vehicles.

Blog Article: Here Is How Our Solar Technology Could Change the Energy Supply in Mobility 

Solar technology has been around for 180 years, even though back then it was dismissed by many scientists due to the domination of energy technologies based on the burning of coal. However, as Bob Dylan famously sang in the 1960s, “the times they are a-changing”, and the Sion’s solar technology might be one example of many.
