Hyundai Launches First Car with Solar Roof Charging System

Hyundai Motor’s solar roof charging system makes its debut on the New Sonata Hybrid. The system supports the vehicle’s electric power source, improving fuel efficiency and reducing CO2 emissions. This eco-friendly technology will provide vehicles with additional electrical power, as well as increasing fuel efficiency and driving range.

In the coming years, Hyundai will roll out the technology to other vehicles across its range. This is the latest application of a smart solution from Hyundai advancing the mobility industry towards a more sustainable future.

“Solar roof technology is a good example of how Hyundai Motor is moving towards becoming a clean mobility provider. The technology allows our customers to actively tackle emissions issue. We are striving to further expand the application of the technology beyond eco-friendly vehicle line up to vehicles with internal combustion engine,” stated Heui Won Yang Senior Vice President and Head of Body Tech Unit of Hyundai Motor Group.

The solar roof system includes a structure of silicon solar panels that are mounted on the car’s roof. Being able to charge even while driving, the solar roof system can charge 30 to 60 per cent of the battery per day. With 6 hours of daily charging, it is expected to increase drivers’ travel distance by an extra 1,300 km annually.

The electricity from the solar panel is not used directly by any of the systems in the car. It is converted to the standard voltage by the controller, then stored in the battery. Hyundai Motor took not only efficiency but also design into account while developing the solar charging system.

“While the solar roof system currently plays a supporting role, it opens up perspectives for vehicles that no longer need fossil fuel to operate,” Yang concluded.

The New Sonata Hybrid

The New Sonata Hybrid is equipped with the world’s first Active Shift Control (ASC) technology and solar roof charging system. It boasts a hybrid-exclusive design with enhanced dynamic elements, as well as a Smartstream G2.0 GDi HEV engine and 6-speed hybrid transmission. Hyundai’s new model also supports a ‘Digital Key’ function via a dedicated smartphone app.

The New Sonata is now on sale in Korea and will soon be sold in North America. Hyundai currently has no plans to expand sales of this model to the European market.
