The solar roof as an eco-innovation
It does not matter if vehicles are powered by a combustion engine or an electric/hybrid drive: both require electricity – either for the drivetrain or for ancillary devices (navigation, entertainment etc.).
Back in 1989, Webasto had already launched series production of a vehicle with a solar roof which generates electricity using integrated solar cells.
With combustion engines, electrical energy is primarily used to power auxiliary units, such as a vehicle's auxiliary ventilation system. With electric and hybrid vehicles, the energy generated by the solar cells can be stored in the vehicle's powertrain battery, thereby contributing to charging the battery.
The European Union approved our solar roofs as an eco-innovation in 2013. This seal of approval is given to pioneering vehicle-specific technologies that have been proven to reduce the CO2 emissions of new vehicles. Automobile manufacturers can offset this CO2 saving against the fuel consumption of the overall fleet.
