Hyundai and Kia reveal roof-mounted solar charging system technology

The eco-friendly solar-based charging system charges a vehicle’s battery using solar panels on its roof or body, improves mileage and reduces CO2 emissions

Hyundai and Kia Motors both stated that that technology will be introduced on selected Hyundai Motor Group vehicles. Electricity- generating solar panels will be incorporated into the roof or hood of the vehicles, will support internal combustion, hybrid and battery electric vehicles with additional electrical power, increasing fuel efficiency and range.

The technology is developed to be the vehicle’s main power source, and is expected to improve mileage and reduce CO2 emissions. It will be able to charge batters of not only eco-vehicles but also of internal combustion engine (ICE) vehicles, thereby improving fuel efficiency.

Hyundai Motor Group is developing three types of solar roof charging systems: The first-generation silicon solar roof system, the second-generation semi-transparent solar roof system, and the third-generation lightweight solar-lid on the vehicle’s body.

The first-generation solar roof system, which will be applied to hybrid models, includes a structure of mass-produced silicon solar panels that are mounted on an ordinary roof. This system can charge 30-60% of the battery per day, depending on the weather and environment conditions.

The second-generation semi-transparent solar roof system will be applied to vehicles with ICE, for the first time in the world. They will provide transmission panel. The semi-transparent solar panels are applied to a panoramic sunroof, maintaining transparency whilst charging an electric vehicle’s battery or an additional battery mounted on an internal combustion engine vehicle.

Hyundai plans to launch the first generation of this technology into its vehicles after 2019 to help meet global regulations targets and improve vehicle fuel efficiency.
