Top Solar participated in the InternationalGreen Energy Expo 2021 held at EXCO, Daegu from April 28 (Wed) to 30 (Fri) andintroduced the solar power plant construction and 1MW-class all-in-one system.

Since its establishment in 2002, Top Solar,a company that creates light and energy, has been showing remarkableachievements in the field of new and renewable energy such as solar powergeneration business and solar power-linked ESS power generation business as asolar power EPC company.

Top Solar developed an analysis model ofthe power generation forecasting system scheduled to be introduced in thesecond half of this year based on big data through the operation of 1,400 solarpower plants through the overall reorganization of the O&M business fieldthis year. Through this, Top Solar will predict bad weather and open up newpaths for all regions in Korea.

At the Green Energy Expo exhibition hall,AVING News met Planning Purchase Office Manager Lee Yun-sang to interview onthe development of solar power generation business.

Q1. Company Overview

A. Lee: Top Solar is a company thatprovides total solutions related to solar power, providing everything from A toZ related to solar power, from business development to construction, licensing,self-manufacturing, PF financing, and O&M.

Up to now, Top Solar's solar power plantconstruction capacity had been 800MW with direct management and process from2002 to 2020. In addition, the ESS system achieved 1.1GWh performancecumulatively. Based on this much construction ability, experience, andknow-how, it is in a leading position in the domestic market.

Q2. Flagship products at the exhibition

A. Lee: At this 2021 International GreenEnergy Expo exhibition, we have showcased the Solar Force lineup, which boastssuperior technology.

In the past, switchgear and inverter hadbeen delivered separately. But, Top Solar provides an all-in-one type solutionin which the inverter and switchboard are integrated into one. Thanks to this,we were able to reduce the air. Also, we have showcased the product with adouble-sided reflector optimized for a double-sided module.

Q3. Specialized advantages of Solar Force

A. Lee: Solar Force is a solar reflectorjointly developed by POSCO C&C-KCC and Top Solar on April 21.

We increased the reflectance by maximizing the light reflection. Also, it boasts unbeatable durability by applying POSCO's PosMAC, which does not generate rust at all. Thanks to this, we were able to maximize power generation.

Q4. Recently, fire from ESS is becoming a big issue. How does Top Solar ensure safety?

A. Lee: So far, Top Solar has accumulatedmuch experience while constructing 150 ESS systems rating 1.1GWh. Only thecompanies with a high understanding in batteries should carry out constructionby following the systematic construction procedures, but due to timeconstraints and pressure for completion, many constructions are under qualification,and this often leads to fire.

Top Solar strictly complies with thestandards and construction procedures of electrical safety construction. TheESS battery enclosure is designed specifically for temperature, humidity, anddust resistance, and the cause of fire is minimized by separating and isolatingall facilities other than the battery.

Also, we have installed a fireextinguishing facility in the battery compartment, and we designed it toprevent the spread of fire as much as possible by installing the batterycompartment temperature detector and smoke detector. Glass wool panels, whichare non-combustible materials, were used for the battery compartmentinsulation, and the air conditioning system is a 2N1 system that was designedto protect the temperature of the battery compartment even if one airconditioning system is turned off.

Q5. The level of Korea’s solar system, and what are the advantages of solar power over other power generators

A. Lee: Korea started solar power in 2007,but at that time, there was almost no solar power products. Most of theproducts sold were from foreign companies, and most of the Korean companiesthat were making solar power products were small.

However, tremendous results came out withina short period of time, and now, there are a lot of global companies that areleading the global market. Top Solar also recorded great growth in theEngineering Procurement Construction (EPC) field. In 2020, it entered Cambodiaand built a solar power plant, and installed solar power in Vietnam and thePhilippines.

The company’s solar power constructioncapabilities and price competitiveness laid the foundation for growth in bothKorean market and also the overseas market.

Q6. When comparing wind power and solar power, what is good about solar power?

A. Lee: The biggest advantage of solarpower is that it can be installed regardless of location and time. However,wind power plants have regional restrictions, and there are civil complaintsdue to the sound of blades cutting through the wind.

Considering this point, we can say thatsolar power is suitable for Korea.

Q7. Future plans

A. Lee: Top Solar is planning to develop alarge-scale solar system. In 2020 alone, about 300MW solar power plant wasconstructed. This year, we are targeting about 500MW. Also, we will do our bestto ensure that small businesses do not suffer damage related to theinstallation of solar power plants.

The 18th International Green Energy Expo isKorea’s largest, one of Asia’s top 3 and the world’s top 10 new and renewable energyexhibitions, and the only exhibition jointly organized by the four majorassociations. The exhibition will cover △Solar power △ESS (energy storagesystem) & battery △Smart grid technology △Wind power and △New and renewableenergy. This exhibition is hosted by Daegu Metropolitan City and Gyeongsangbuk-doand organized by EXCO, KNREA, KOPIA, KWEIA, and KHIA.
