The Korean automaker hasn't specified which models will be available with the system, but the hybrid versions of the Hyundai Sonata and Ioniq, as well as the Kia Optima and Niro, seem to be good bets.

The first-generation system will be applied to hybrid models, and will feature a structure of silicon solar panels that are integrated into a standard auto roof.

Electricity-generating solar panels will be incorporated into the roof or the hood of vehicles and will support internal combustion, hybrid and battery electric vehicles with additional electrical power, increasing fuel efficiency and range.

Korean auto manufacturer Hyundai will adopt solar panel charging technology for electric and hybrid vehicles from next year, including cars released under the Kia brand.

Hyundai and Kia branded vehicles will gain improved mileage, reduced Carbon dioxide emissions and improved fuel efficiency in the case of hybrid and petrol cars, it is claimed.

The second is for vehicles with internal combustion engines and can be used in panoramic sunroofs, letting light through to driver and passengers while topping up the auto battery. It's capable of charging 30-60 percent of the battery during a day, depending on the weather.

The third stage, which is now the subject of a pilot study, will see fuller integration of solar panels into the vehicle structure, on both the roof and hood.

Hyundai says the first vehicles from it and Kia Motors to launch using the first-generation solar panels will arrive after 2019. Power generated from this type of roof could be used for the air conditioning and seat heating systems. The panels will charge the main battery or an auxiliary battery included as part of the system while blending more naturally into the sunroof structure. It integrates into a panoramic sunroof to simultaneously let light in and charge the vehicle's battery.

For cars with ICEs, a semi-transparent solar roof will be used, which is being described as a world-first.

When a 100W solar panel is equipped, it can produce up to 100Wh of energy (in ideal conditions: summer noon, 1000 W/m2 intensity of radiation).
