With the recent rise in environmental pollution issues, movements to reduce carbon emissions are increasing worldwide., Interest in renewable energy is also increasing. There is. Environmentally friendly renewable energy is solar energy, Geothermal energy, Bio energy , Energy that is converted into renewable energy such as marine energy and used.

In particular, interest in BIPV, which produces solar energy among new and renewable energy sources, is growing. BIPV is a building-integrated photovoltaic module that supports building energy self-sufficiency by playing the role of building subsidiary materials and generating electricity through sunlight at the same time. Help. As a result, BIPVthe demand for BIPV is increasing.

SG Energy is developing and producing BIPV modules, since its establishment, >BIPV is said to be growing in the market. I met Jinseop Lee, CEO of SG Energy, to hear more details.

Please introduce your company

SG Energy established in 2019is a building-integrated photovoltaic module(BIPV) specialized manufacturing company. .

Since its establishment, it has ranked 4 in domestic sales volume for 4 consecutive years 1, and with the expansion of the manufacturing line at the beginning of this year, It boasts a quick response to domestic BIPV manufacturing volume by massively expanding production manpower. Also, an anti-reflective color released in 20203< span>BIPV The module is recognized for reliability such as power generation, discoloration, exfoliation.

Please explain the main business details

SG Energy's main businessBIPV The module is a building external photovoltaic power generation system that uses the building envelope as a solar panel. In addition to generating electricity from sunlight and supplying it to consumers, solar modules are used as building exterior materials to reduce construction costs, It is used as a design element that increases value.

As for general solar modules, it is difficult for SMEs to gain competitiveness due to the preoccupation of domestic large companies and Chinese companies that supply high-efficiency modules with unit price competitiveness and standardized modules through mass production. However, BIPV The module is an on-site customized production product that is close to small-lot production of various products, so even small and medium-sized businesses can gain competitiveness. So, based on its quick response and accumulated technology, BIPV established a bridgehead to preoccupy the market.

Color as a building exterior materialBIPV As for modules, products with excellent harmony with buildings eventually lead to marketability. So, in the product development stage, SG Energy focused on selecting textures and colors that can harmonize well with buildings. It is currently receiving much love in the construction market as it has been developed with a pastel tone color and texture most similar to composite panels used for building exterior materials.

In addition, we have secured the technology to implement various colors to harmonize with the building, Basically 10< span>color BIPV modules have been released and production of BIPV modules of all colors is possible according to customer's request do.

Color BIPV The factors that determine the unit price of a module are the unit price of colored glass and the rate of output degradation. Through these two factors, it is no exaggeration to say that the ease of entry into the color module market is secured BIPV . SG Energy's color BIPV The power generation efficiency of the module is 88% BIPV remarkably improved efficiency compared to existing color products, This efficiency improvement is unit price competitiveness and ease of market entry.

The other company's color BIPV The module penetrates the color and the light reaches the solar cell, resulting in output variation for each color . However, such color BIPV The output deviation of the module affects the durability of the product along with the power loss of the photovoltaic system span>. On the other hand, SG Energy's color BIPV module applies a technique to prevent output deviation for each color, so it provides the same output without output deviation in all colors. . Therefore, it can be said that it is very easy to configure the system.

If you have any future goals or directions

current color BIPV module is normal BIPV about 2.5< /span>The cornerstone for entering the market has been laid, It is expected that it will take time for it to be generalized due to the high cost yet span>. So, SG Energy aims to generalize color BIPV modules through efficiency improvement and product standardization to secure unit price competitiveness. .

Launched colors BIPV The module is a G/T type of product, Limited to application of exterior building materials that do not require insulation performance such as composite panels and marble. However, as the mandatory supply ratio increases every year, high efficiency of products is required to cover the mandatory supply ratio. So, color BIPV modules through the development of a curtain wall type high-insulation color solar system in the spandrel section or non-vision section of the glass construction finish section. .

In addition, BIPV The module has a major drawback of loss of power generation due to the limitation of installation angle. So, SG Energy developed a high-performance BIPV module with power generation improvement technology to create economical value as a power generation device. < span>BIPV We want to stand at the center of manufacturing companies.
