At this year’s National Two Meetings, carbon peak and carbon neutrality were included in the government work report for the first time. From the specific details to various fields, my country’s building carbon emissions accounted for more than 1/3 of the total carbon emissions. Building carbon emission reduction will be an important way to achieve carbon neutrality.

Building Integrated Photovoltaics (BIPV) is a technology that integrates solar power (photovoltaic) products into buildings. The generated electricity can also be used by buildings. It has truly realized the common development of building green and economy. The form of carbon reduction is one of the effective ways to solve the carbon emissions of buildings. Therefore, promoting the large-scale market application of BIPV has an important role and significance for the achievement of my country's carbon neutrality goal.

On March 24, a reporter from "China Building Materials News" walked into Longji New Energy Co., Ltd.'s first old factory building renovation (BIPV) project. This BIPV project, built on the roof of the Shaanxi Thomson Power Technology Co., Ltd. plant, has a total installed capacity of 226 kilowatts. A total of 1,708 pieces of 135 watt roof modules have been installed. The estimated power generation capacity in the first year is about 250,000 kWh and the total power generation in 25 years. The amount is about 5.63 million kWh. In 25 years, a total of 1931 tons of standard coal can be saved, 5349 tons of carbon dioxide emissions and 161 tons of sulfur dioxide emissions can be reduced, which has played a demonstrative role in achieving the building carbon reduction target.

It is understood that Longi is a leading enterprise in the domestic photovoltaic industry and has been paying close attention to the development of the BIPV industry for many years. Since its subsidiary Longi New Energy launched the Longding BIPV product solution last year, it has successively completed and delivered a number of BIPV projects for customers. The plant of the Thomson BIPV project visited this time has been in use for 8 years. Rain leakage and damage have brought many inconveniences to the production and safety of the enterprise. After the program design of Longi New Energy, the company will not affect the normal production and operation of the enterprise. Realize both roof renovation and long-term green development of clean energy and electricity. The Wuxi Liancheng Kex project, which was officially delivered on January 8, is the first prefabricated BIPV application case in Jiangsu Province. The project capacity is 1.6MW and the average annual power generation is about 1.48 million kWh. It not only reduces electricity costs, but also helps Enterprises have reduced carbon emissions, and in the context of my country's full implementation of carbon neutrality goals, adjustment of energy structure, and promotion of the development of green buildings, it has brought an exemplary role for the low-carbon development of high-end manufacturing in Jiangsu and even East China.

Take Longji shares as an example. In terms of production capacity, it already has a 1GW capacity plan. As the market further expands in the future, it will expand accordingly. It is believed that during the "14th Five-Year Plan" period, my country's BIPV industry will achieve great development in the application end, manufacturing end, and power consumption.

In terms of policies, Shanghai recently issued the "Implementation Opinions on the City’s 14th Five-Year Plan on Accelerating the Promotion of New City Planning and Construction". In terms of optimizing the energy supply structure and supporting Shanghai’s first carbon peak, distributed photovoltaics have become a “key point”. ". In addition, nearly 20 provinces and cities including Beijing, Shandong, Zhejiang, Jiangsu, Henan, Shanxi, Yunnan, Fujian, and Chongqing have issued policies to support the development of distributed photovoltaics. Zhejiang Province has proposed that during the "14th Five-Year Plan" period, 13 million kilowatts of photovoltaic power will be added, and building-integrated photovoltaic power generation systems will be actively developed and applied. It can be foreseen that BIPV will usher in a period of rapid development in the future.

During the two sessions this year, in order to help the development of the BIPV industry, the All-China Federation of Industry and Commerce and many representatives of the National People's Congress also put forward relevant policies to promote the development of the BIPV industry. Among them, the proposal of the All-China Federation of Industry and Commerce proposes to increase policy support, improve national and industry standards, set clear building energy-saving development goals, give a certain degree of differentiated electricity price subsidies, and encourage local governments to carry out BIPV pilot city construction. opinion.

In response to this proposal, Chen Pengfei, general manager of Longji New Energy, expressed in an interview that he hopes that the BIPV industry will be included in the "14th Five-Year" renewable energy development plan and "14th Five-Year" building as a new type of clean energy application mode and building application mode. Industry development plans can clearly state in the form of policies a certain proportion of energy self-sufficiency in certain newly built and renovated and expanded buildings, and specify some BIPV applications in the form of policies in public buildings, encourage high-energy-consuming buildings to use BIPV products, and give a certain degree Photovoltaic or green construction subsidies.

In order to achieve a better integration of BIPV and buildings, Chen Pengfei believes that the previous BIPV industry has always been dominated by photovoltaic technology thinking, and always wanted to use photovoltaic modules to replace building materials. BIPV led by this thinking is "patching" "It is necessary to form a consensus that the first attribute of BIPV products is building materials.
