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

Hyundai Energy Solution participated in theInternational Green Energy Expo 2021 held at EXCO, Daegu from April 28 (Wed) to30 (Fri) and introduced its 250W solar roof model.

In this exhibition, the company exhibited a250W solar roof which has a 25% increase in output compared to existingproducts 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 solarpower business in 2004 and produced photovoltaic cells and modules in Korea,and is also solidifying its position as a total photovoltaic solution providerby continuously expanding the photovoltaic solution business. Hyundai EnergySolutions is advocating the strategy to maximize safety by incorporating alarge number of offshore structure design and corrosion prevention technologiesof the affiliated offshore plant company Hyundai Heavy Industries to its ownsolar modules.

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

Q1. About solar roof

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

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

A. Kim: Applying solar energy toautomobiles is a task we are facing.  Asshown at the exhibition, a concept car that can incorporate sunlight into allpossible areas was created. In future development, a solar system optimized forvehicles will be applied.

Moving onto the electric vehicle era, theconcept of fuel economy is changing to the concept of how much distance can betraveled 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 bedriven when charging solar power for about 4 hours a day.

Q3. Future plans

A. Kim: We are currently discussing fordevelopment and cooperation with commercial vehicle companies. Also, if avehicle 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 isKorea’s largest, one of Asia’s top 3 and the world’s top 10 new and renewableenergy exhibitions, and the only exhibition jointly organized by the four majorassociations. 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 andorganized by EXCO, KNREA, KOPIA, KWEIA, and KHIA.
