BIPV market is broad

With the development of steel structure technology and the application of steel frame system, the envelope no longer needs to bear the load, thus promoting the development of lightweight envelope such as glass curtain wall. Under the dual-carbon goal, the requirements for green buildings will continue to increase. As an important part of building energy conservation, the BIPV market has a broad prospect. With the high relevance of the engineering side, steel structure enterprises will expand their business and layout the BIPV business. Business extension, actively layout the photovoltaic building integration (BIPV) business. Photovoltaic building integration is a concept of applying solar power generation in the building field. It is different from the way that BAPV installs photovoltaic power generation equipment on the building surface and uses the building as the support carrier of photovoltaic array. BIPV combines photovoltaic modules with building materials to make photovoltaic modules become part of the building envelope. BAPV is commonly used in building roofs that do not occupy additional space. In contrast, BIPV, which replaces curtain walls, has higher requirements for photovoltaic modules. In addition to meeting the power generation function, it also needs to take into account the basic functional requirements of building structures such as fire protection and thermal insulation.

With the continuous progress of photovoltaic power generation technology, the continuous growth of installed capacity, and the rapid decline of construction costs, centralized photovoltaic power stations have fully entered the "era of parity" since 2021, and no longer need financial subsidies. The rapid decline of PV costs has laid a necessary foundation for the large-scale development of PV building integration.

The state encourages the development of PV building integration, and the BIPV market has broad prospects. In October 2021, the State Council issued the "Action Plan for Carbon Peak by 2030", proposing that by 2025, the photovoltaic coverage rate of new public buildings and plant roofs should strive to reach 50%. In March 2022, the Ministry of Housing and Urban-Rural Development issued the "Fourteenth Five-Year Plan" for the Development of Building Energy Efficiency and Green Buildings, which required the active promotion of building photovoltaic applications, encouraged the government to invest in public welfare buildings to strengthen solar photovoltaic applications, and proposed the goal of adding 50 million kilowatts of solar photovoltaic installed capacity of buildings nationwide by 2025. In addition, many local governments have issued local subsidy policies for PV building integration. Under the background of carbon peak and carbon neutrality, the gradual implementation of the policy documents has laid a solid foundation for the integration of photovoltaic buildings, and the market prospect of BIPV is very broad.

The industry leader accelerated the layout of the BIPV market. Seiko steel structure entered the BIPV market in 2014, continuously strengthened the research and development of low-carbon buildings and professional technologies, and developed a variety of green building products, with first-mover advantages. The revenue of the subsidiary Seiko Energy in 2021 reached 510 million yuan, accounting for 3.4% of the total revenue of the year, and the net profit was 20 million yuan, accounting for 2.9% of the net profit of the year; Southeast Grid was established in 2021 and Zhejiang Southeast Grid Foster Carbon Neutralization Technology Co., Ltd. was jointly established with Foster New Energy Development Co., Ltd. In September 2022, a strategic cooperation agreement was signed with Daycare Photovoltaics to jointly develop and produce high-end photovoltaic modules for personalized BIPV building scenarios; Hangxiao Steel Structure increased the capital and shares of Hete Optoelectronics in April 2022, and continued to promote the expansion of BIPV business based on its perovskite advantages.
