LG Electronics participated in theInternational Green Energy Expo 2021 held at EXCO, Daegu from April 28 (Wed) to30 (Fri) and introduced Neon R, its new neon H bifacial by using the N-typecell. N-type cells are mainly used for premium solar modules due to their highefficiency.

While ESG (environmental, social, andgovernance) has emerged as a topic of survival for global companies, LGElectronics plans to establish itself as an eco-friendly partner by launchingnew high-efficiency solar modules.

At the Green Energy Expo exhibition hall,AVING News met LG Electronics’ Solar Power Marketing Senior Researcher ChoiJeong-gyu to interview on Neon H.

Q1. Company introduction

A. Choi: Since LG Electronics starteddeveloping solar power in 1985, it began mass production in 2010 and hasestablished itself as a manufacturing company that sells solar power around theworld. Based on the technology used for home appliances in the past, thecompany develops and sells durable solar power products that are stable andlast a long time.

Q2. Introduction of flagship products

A. Choi: There are largely N-type andP-type solar products. The P-type is divided into general cells, and the N-typehas increased power generation with double-sided power generation structurethat receives light from both front and back.

LG Electronics is the only company in Koreato make products with N-type cells. N-type is widely sold for home use not onlyin Korea but also abroad. There are two types of N-type lineups, reduced powergeneration modules and double-sided power generation modules, and LGElectronics' strengths are incorporated into them.

In this exhibition, we released the newproduct Neon H bi-facial using N-type cells and Neon R. Using half-cuttechnology, the resistance value was lowered to increase the output. Based onthis safety, we have a high level of product warranty and output warranty. TheN-type product's output warranty is 25 years and is a free warranty thatmaintains the performance of up to 90.6% of the initial output. The productwarranty is also available for up to 25 years. Through this, we can operate astable solar power business from a long-term perspective and obtain higherprofits.

Q3. What is the reason for the high output guarantee?

A. Choi: LG's own technology is used inN-type product. It is the cello technology that increases power efficiency andminimizes power reduction through 12 bus bars. Also, the characteristic ofN-type products is that the output volume is increased through double-sidedpower generation. As a result, N-type products can maintain over 90%performance and have a 25-year warranty.

Q4. Product strengths and examples

A. Choi: LG’s Building IntegratedPhotoVoltaic (BIPV) is made with its own Back Contact Cell. The back contactcell, which maximizes the front output by turning the front electrode to therear, is both functional and has aesthetical values.

We also contribute to improving theaesthetics of the building exterior as an exterior material by introducing aback contact cell with an electrode located on the back side into BIPV. Withthese BIPV products, we built the first Zero Energy House in Korea. Zero EnergyHouse is made with its own BIPV ESS products. Electricity generated throughBIPV is stored in ESS and used in daily life. Zero Energy House uses all theelectricity necessary for daily life only with sunlight without any extra cost.

Q5. What kind of product is solar car roof?

A. Choi: We provide various solutionsthrough various technologies that utilize solar power as well as solar modules,ESS, and BIPV. One of them is solar car roof, the customizable product which wedeveloped.

It was manufactured as N-type, and providepower to drive a vehicle by generating electricity through a cell. This is dueto the high power generation and efficiency that only the N-type has.

Q6. Future plans

A. Choi: We are doing our best to developproducts that has higher output and is also aesthetics by using back contactcells. We will take one step at a time to make a new and renewable energysociety and new and renewable energy management.

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.
