[2021 Green Energy Expo Interview] Hyundai Energy Solutions expects 5km drive with 4-hour solar roof charge

Hyundai Energy Solution participated in the International Green Energy Expo 2021 held at EXCO, Daegu from April 28 (Wed) to 30 (Fri) and introduced its 250W solar roof model.

In this exhibition, the company exhibited a 250W solar roof which has a 25% increase in output compared to existing products by applying high-efficiency cell and high-power module technology, revealing a mobility energy solution that combines solar energy and vehicles.

Hyundai Energy Solutions entered the solar power business in 2004 and produced photovoltaic cells and modules in Korea, and is also solidifying its position as a total photovoltaic solution provider by continuously expanding the photovoltaic solution business. Hyundai Energy Solutions is advocating the strategy to maximize safety by incorporating a large number of offshore structure design and corrosion prevention technologies of the affiliated offshore plant company Hyundai Heavy Industries to its own solar modules.

At the Green Energy Expo exhibition hall, AVING News met Hyundai Energy Solution’s Senior Researcher Kim Mun-seok to interview on solar roof.

Q1. About solar roof

A. Kim: Solar roof is a product that is installed on the roof of an electric vehicle to charge energy with batteries through solar power generation to further increase the mileage. The previous photovoltaic module installed in Prius had a low output. But, Hyundai’s solar roof can further increase its output by integrating the latest module technologies such as half-cut, multi-wire, and high-transitive module technology. Thanks to this, the output is maximized compared to the previous Prius model.

Q2. In what way is solar roof applied to automobiles? What is the effect when equipped?

A. Kim: Applying solar energy to automobiles is a task we are facing.  As shown at the exhibition, a concept car that can incorporate sunlight into all possible areas was created. In future development, a solar system optimized for vehicles will be applied.

Moving onto the electric vehicle era, the concept of fuel economy is changing to the concept of how much distance can be traveled with how much power rather than the conventional fuel economy concept. When only the roof is installed, it is expected that about 5km more can be driven when charging solar power for about 4 hours a day.

Q3. Future plans

A. Kim: We are currently discussing for development and cooperation with commercial vehicle companies. Also, if a vehicle model that can use solar roof technology is decided in the near future, we will do our best to ensure smooth delivery.

The 18th International Green Energy Expo is Korea’s largest, one of Asia’s top 3 and the world’s top 10 new and renewable energy exhibitions, and the only exhibition jointly organized by the four major associations. The exhibition covers △Solar power △ESS (energy storage system) & battery △Smart grid technology △Wind power and △New and renewable energy. This exhibition is hosted by Daegu Metropolitan City and Gyeongsangbuk-do and organized by EXCO, KNREA, KOPIA, KWEIA, and KHIA.
