Park Il-joon, 2nd Vice Minister of Trade, Industry and Energy, visited the integrated photovoltaic (BIPV) demonstration complex of the Seoul Energy Corporation building on October 11 to check the status of the operation and encouraged efforts to cultivate a full industrial ecosystem and create. new markets.
BIPV does not require a separate site or external structure, it is compatible with architectural design, so it is relatively easy to ensure acceptability, and it can be applied to horizontal and vertical surfaces in a variety of ways, so it is suitable for a domestic environment with a narrow land area and many tall buildings.
This site visit was conducted to check the competitiveness of Korean companies and domestic conditions If BIPV is activated, it is expected to contribute greatly to the expansion of zero-energy buildings and distributed power sources in the city, and to the improvement and saving of energy. in buildings.
Vice Minister Park Il-joon said, “Unlike general solar power, in the BIPV industry, high value-added technology and design-based product competitiveness are more important than economies of scale. To this end, relevant organizations preemptively reorganize the system and support strengthening the competitiveness of the industrial ecosystem.”
In this regard, the Ministry of Trade, Industry and Energy has prepared a ‘BIPV Industry Ecosystem Revitalization Plan’ to support ensuring competitiveness in the BIPV industry, focusing on high added value technologies, by gathering opinions from industry and experts.
An intensive BIPV training plan was prepared
The global BIPV market is expected to more than triple from 1.6GW in 2021 to 5.6GW in 2026. The initial market is mainly formed in the US and Europe, with supply expected to expand in China , India and Australia. In particular, France, China and Switzerland promote subsidy policies specific to BIPV, and subsidies are paid up to twice as much as for general solar power.
Solar power construction in Korea accounts for 32% of the total solar power, but BIPV is only 31MW, which is focused on public institutions. If the zero energy building certification is fully extended to private buildings in 2025, BIPV distribution is expected to expand greatly.
Currently, a commercialization and initial market is being formed that focuses on 10 manufacturers and contractors, and support is provided mainly for mandatory installation, zero energy buildings, and installation support.
Inadequate construction standards related to BIPV and KS certification are identified as difficulties in activating the BIPV industry ecosystem. Besides the general definition of BIPV, there is no separate classification standard according to the type of installation, so the difference between BAPV is not clear. In addition, there is no mandatory regulation for KS certification, so when building a module that has received KS certification for general solar power, the performance test for building materials is omitted.
The capacity-oriented deployment system and the distributed support system are also raised as barriers to BIPV deployment. In the case of REC, the same weight is given according to the installed capacity regardless of the type of solar power construction, and it is difficult to adopt BIPV with low economic efficiency.
Accordingly, the Ministry of Industry, under the vision of “turning the urban construction forest into a smart power plant in the horizontal and vertical” as a vision, establishes a BIPV accreditation system, strengthens institutional support to create initial market, supports high value -added technology innovation, and expands BIPV application from the design stage.
Classification criteria according to location, shape, function, etc. are prepared so that they can be clearly distinguished from BAPV and types of building installations. A committee made up of related experts is implemented to check and improve from time to time. In addition, it comprehensively presents standards and performance guidelines under the laws relating to architecture and electricity that must be followed in the design and construction of all types.
BIPV KS certification is mandatory for safety and structural performance verification. When supporting government supply projects, etc., it will be mandatory to use BIPV KS certified modules (KS C 8577), and it will be improved so that they can receive the performance test for building materials required for BIPV.
In order to strengthen institutional support for the creation of the initial market, the subsidy support will be reorganized with a focus on BIPV. Subsidy support is preferentially provided to local governments that actively promote the spread of BIPV, such as implementing local government-led BIPV delivery projects.
By analyzing the installation difficulty and economic feasibility by type of BIPV, the incentives for installing BIPV, such as adjusting and subdividing the solar correction coefficient, will be strengthened, and the installation area will be expanded in the sector public by gradually expanding the application. area, target buildings, and introducing mandatory external walls.
After securing sufficient installation case data, a plan to improve REC weights for BIPV will be prepared through research services, and a separate weighting for BIPV will be reviewed.
In connection with the public housing supply project and the creation of a zero energy pilot complex, the pilot and demonstration projects relevant to BIPV will be expanded. In addition, in order to build up the history of BIPV in the public sector by supporting the progress in procurement, comprehensive guidelines are prepared on the registration procedure for outstanding procurement products, performance standards, examination system, and specification method.
Intensive support for market-making research and development. Through this, by 2026, △module cost reduction of 28%, △module lifetime of 12%, △facility utilization rate of 17%, etc. will be achieved. In particular, it realizes a reduction in maintenance and replacement costs by developing BIPV modules and materials that ensure long-term reliability for more than 25 years.
Establishing an open BIPV DB and design tool related to Building Information Modeling (BIM). In accordance with the expansion of mandatory BIPV design, an open library service is implemented by developing DB domestic BIPV product information and an optimal design algorithm.
In addition, incentives and incentives will be expanded so that BIPV can be actively applied from an architectural design. BIPV design work is added to the scope of engineering design work of the public sector procurement project to prepare the basis for the price calculation. In the long term, we will prepare a BIPV design incentive payment system and review pilot support for design offices and architectural offices when BIPV facilities are reflected in buildings.
