In the context of carbon neutralization, the large-scale market application of BIPV is of great significance
at this year's national two sessions, carbon peak and carbon neutralization were written into the government work report for the first time. From the specific details to various fields, China's construction carbon emissions account for more than 1/3 of the total carbon emissions, so solving the construction carbon emission reduction will be an important way to achieve carbon neutralization
photovoltaic building integration (BIPV) is a technology that integrates solar power generation (PV) products into buildings. The generated power can also be provided to buildings, which truly realizes the common development of building green and economy. Among many forms of building carbon reduction, it is one of the effective ways to solve building carbon emissions. Therefore, promoting the large-scale market application of BIPV plays an important role and significance in achieving the goal of carbon neutrality in China
on March 24, China Building Materials News entered the first photovoltaic building integration (BIPV) project of Longji new energy Co., Ltd. The BIPV project, built on the roof of the plant of Shaanxi Thomson Power Technology Co., Ltd., has a total installed capacity of 226kw, a total of 1708 pieces of 135 single tile roofed components, and is expected to generate about 250000 kwh of power in the first year, with a total power generation of about 5.63 million kwh in 25 years. A total of 1931 tons of standard coal can be saved in 25 years, 5349 tons of carbon dioxide emissions can be reduced, and 161 tons of sulfur dioxide emissions can be reduced, It has played an important role in achieving the goal of building carbon reduction. The continuous improvement of the concentration or monopoly of the demonstration industry is an important trend in the development of biomedical materials industry
it is understood that Longji Co., Ltd. is a leading enterprise in the domestic photovoltaic industry, and has been paying great attention to the development of BIPV industry for many years. Since its subsidiary Longshi temporarily shut down and worked again after the water temperature fell last year, Zhongji new energy company has successively completed and delivered a number of BIPV projects for customers since it launched Longding BIPV product solutions. The Thomson BIPV plant visited this time has been in use for 8 years, and the rain leakage and damage have brought many inconveniences to the production and safety of the enterprise. Through the scheme design of Longji new energy, without affecting the normal production and operation of the enterprise, the enterprise can realize the roof renovation and transformation and the long-term green development of clean energy power. The Wuxi Liancheng Kekes project, officially delivered on January 8, is the first assembled BIPV application case in Jiangsu Province. The project capacity is 1.6MW, and the annual average power generation is about 1.48 million kwh. It not only reduces the cost of electricity, but also helps enterprises reduce carbon emissions. Under the background of China's full implementation of the carbon neutralization goal, adjusting the energy structure, and promoting the development of green buildings, It will play an exemplary role in the low-carbon development of high-end manufacturing industry in Jiangsu and even East China
taking Longji as an example, it has 1GW capacity planning in terms of capacity, and will expand accordingly with the further expansion of the market in the future. It is believed that during the "14th five year plan" period, China's BIPV industry will achieve great development in application end, manufacturing end, power consumption and other links
in terms of policies, Shanghai recently issued the "Implementation Opinions on accelerating the planning and construction of new towns during the 14th five year plan". In terms of optimizing the energy supply structure and supporting Shanghai to take the lead in reaching the peak of carbon, distributed photovoltaic has become the "focus". 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 photovoltaic. Zhejiang Province proposed that during the "14th five year plan" period, 13 million kilowatts of photovoltaic power generation will be added, and actively develop and apply the building integrated photovoltaic power generation system. It can be predicted 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 BIPV industry, the all China Federation of industry and Commerce and a number of deputies to the National People's Congress also mentioned that the progress of plastic granulator technology is closely related to the development of the whole national economy, and put forward relevant policies to promote the development of BIPV industry. Among them, the proposal of the all China Federation of industry and Commerce proposed to strengthen policy support, improve national and industrial standards, set clear development goals for building energy efficiency, give a certain degree of differentiated electricity price subsidies, and encourage local governments to carry out the construction of BIPV pilot cities
in response to this proposal, Chen Pengfei, general manager of Longji new energy company, said in an interview that he hoped that the BIPV industry, as a new clean energy application mode and building application mode, would be included in the "14th five year plan" renewable energy development plan and the "14th five year plan" construction industry development plan, and that it would be able to clearly put forward in the form of policies to clarify the proportion of energy self-sufficiency in certain new and reconstructed buildings, Define some BIPV applications in public buildings in the form of policies, encourage the application of BIPV products in high energy consuming buildings, and give a certain degree of photovoltaic or green building subsidies
in order to realize the better integration of BIPV and buildings, Chen Pengfei believes that the previous BIPV industry has always been dominated by the technical thinking of photovoltaic, and always wants to use photovoltaic modules to replace building materials. Under this thinking, BIPV is "patching", and a consensus must be formed that the first attribute of BIPV products is building materials
"At present, although the BIPV industry has entered the fast lane of development, there are still some problems to be solved. First, BIPV is still a new industry, and the market acceptance and recognition need to be improved. Second, the standards and specifications are not perfect. At present, the national standards, industrial standards and related specifications of BIPV products, basic research and Utilization Research of construction and promotion, and the collaborative construction of standard atlas of technological development are still missing, and the market The access system also needs to be improved; Third, policy support still needs to be strengthened. At present, the BIPV industry is still in the early stage of development and needs certain policy support and differentiated subsidy support. "
for the risks that may be faced in the process of promoting development, Chen Pengfei suggested, "we should strengthen market access, establish industry standards, and promote the application of high-quality products; at the same time, enterprises in the industry should also strengthen technology research and development and quality control, promote advanced and high-quality photovoltaic products to the society, and prevent fake and inferior products from disturbing the market order."
