Domestic BIPV is ready to start, open a new era of photovoltaic application According to the "building energy efficiency and green number of development" 13th Five-Year Plan ", by 2020 building ultra-low energy consumption, near zero energy building projects reach more than 10 million square meters. BIPV (photovoltaic building integration) is a key technical factor to solve the energy demand of near-zero energy buildings. With the rapid reduction of the cost of photovoltaic industry chain in recent years, photovoltaic buildings have the value of commercial application. From the early household photovoltaic to BIPV, the industry from policy dependence to the era of no subsidies, the rise of spontaneous market demand will open a broad space for the development of BIPV. However, when it comes to the technical aspects of BIPV, many common problems in the industry still need to be further overcome. From manufacturing to construction to operation and maintenance, there are thousands of domestic photovoltaic companies in all aspects, but there are only a handful of BIPV companies, and several of them are traditional construction companies. Globally, although there has been a certain degree of advancement in the concept and standards of BIPV, fewer companies have actually focused on BIPV. The research on BIPV application scenarios is actually not in-depth, and the level of research is uneven. Recently, Beijing issued the "Interim Measures for the Management of Municipal incentive Funds for prefabricated Buildings, green Buildings, and Green Ecological Demonstration Zone Projects in Beijing" (Beijing Construction Law (2020) No. 4), adding prefabricated building incentive policies, improving green building incentive standards, and supporting green construction development. According to the measures, the projects that meet the special standards and obtain the two-star and three-star green building operation marks are respectively given 50 yuan/square meter and 80 yuan/square meter incentive funds, and the high incentive for a single green building project does not exceed 8 million yuan (the original incentive standard is 22.5 yuan /㎡ for two-star projects and 40 yuan /㎡ for three-star buildings). The construction unit or the owner unit can log in the "Beijing Green Building Incentive Fund Declaration System" in the online office hall of the Beijing Municipal Commission of Housing and Urban and Rural Development before the end of May each year to make online declaration.

In contrast, the proportion of photovoltaic buildings in photovoltaic applications in Europe is rising year by year, but in the long run, the future of China's photovoltaic building integration market is still immeasurable. The emergence of photovoltaic building integration is not a coincidence, but based on mature photovoltaic power generation technology, it can also be said to be an important form of photovoltaic technology application, simply put, the solar photovoltaic array installed on the outer surface of the building envelope to provide electricity. According to the form, photovoltaic building integration can be divided into two categories: one is the combination of photovoltaic array and building; The other is the integration of photovoltaic arrays and buildings. We commonly have photoelectric tile roof, photoelectric curtain wall and photoelectric lighting roof. Because the combination of photovoltaic array and building does not occupy additional ground space, it is the best installation way for photovoltaic power generation systems to be widely used in cities, so it has received much attention. According to the data released by the European Industry Association recently, photovoltaic buildings account for 80% of the entire photovoltaic application in Europe, from the growth cycle of products, China's photovoltaic building integration market is still in the market introduction stage, from 2016 onwards, there are enterprises began to engage in photovoltaic tiles, photovoltaic curtain wall and other applications of the production and manufacturing, 531 policy after the introduction of the photovoltaic market fell sharply. For the photovoltaic building integration market may be the starting point of a new market, the market is in the blue ocean stage, it is good for enterprises, and it is worth digging deep. Photovoltaic building integration building is favored by everyone, mainly depends on these advantages 1. The building can provide enough area for the photovoltaic system, and does not need to occupy another land area. Therefore, in recent years, with the rise of the distributed photovoltaic power generation market, urban and rural roofs and other related buildings have become the application objects of photovoltaic power generation, and have begun to promote it nationwide. 2. The support structure of the photovoltaic system can be combined with the building structure to reduce the cost of the photovoltaic system infrastructure. (3) Photovoltaic power generation combined with buildings, photovoltaic power generation can be used for the daily load of buildings, and can be connected to the nearby grid, for the owner to save electricity, but also to obtain additional income, but also can play a role in energy saving and emission reduction. 4. Photovoltaic array can replace conventional building materials in the application of BIPV, saving construction costs, and also saving costs for photovoltaic system installation. 5. The combination of photovoltaic power generation and buildings gives the buildings new vitality, enhances the force of the buildings, and drives the progress of human society and promotes the development of science and technology at a deeper level. From passive to active, the concept of energy utilization to change the amount of photovoltaic industry in China, although ranked first in the world, but the market recognition of photovoltaic buildings is still relatively low, a huge number of building resources to be fully utilized. In fact, the combination of solar energy and architecture is to make solar energy an organic part of the building, putting advanced solar energy.
