Solar roof panels for Koreans
Hyundai Motor and Kia Motors have announced that they plan to introduce solar charging on certain vehicles after 2019 to help meet global regulatory targets and improve vehicle efficiency. The system would be embedded in the roof or the hood of the vehicle to support its main power source as a strategy for improving mileage and reducing carbon-dioxide emissions. The system could be used to charge battery-electric and hybrid vehicles, as well as vehicles with internal combustion engines.
Hyundai Motor Group has indicated that it is set to develop three types of solar charging systems, including a first-generation silicon solar roof system, a second-generation semi-transparent solar roof system, and a third-generation lightweight solar lid on the vehicle's body.
Hyundai estimates that a 100-watt solar panel could produce 100 watts per hour of energy in 1 Sun standards (Summer noon, 1000 W/㎡ intensity of radiation). The generated power is converted to standard voltage by a voltage controller and stored in the battery or used to lower loads from the vehicle's AC generator.
