Hyundai Launches Solar Roof Charging System

Hyundai is launching its first car with a solar roof charging system. The company says the technology will provide vehicles with additional electrical power, as well as increasing fuel efficiency and driving range.

The solar roof charging system will first feature in the latest generation Sonata Hybrid to support the vehicle’s electric power source, improving fuel efficiency and reducing CO2 emissions. In the coming years, Hyundai says it will roll out the technology to other vehicles across its range.

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

Hyundai says the solar roof can charge 30 to 60 per cent of the battery per day with 6 hours of daily charging, and is capable of functioning while the car is in motion. Hyundai expects the roof to increase drivers’ travel distance by an extra 1300km annually.

The system is composed of a solar panel and a controller. Electricity is produced when solar energy – photons of light from the sun – activates the panel’s surface. The electron-hole pairs in silicon cells are then created, and the photons are converted into electricity. The electricity is then converted to the right voltage by the controller, and then stored in the battery.

The new Sonata is now on sale in Korea and will soon be sold in North America. Hyundai says it currently has no plans to expand sales to the European market.
