Reporter: Hello, Mr. Qian, can you first introduce the difference between BIPV and bapv?
Qian Jing: bapv, the module is the module, and the roof is the roof. The module does not undertake the function of building materials, that is, power generation; BIPV is a "building material type" photovoltaic building. As a part of the external structure of the building, BIPV can not only generate power, but also have the functions of building components and building materials.
Reporter: is the product made of superimposed components on the color steel tile BIPV?
Qian Jing: not strictly, it can be called atypical BIPV, because it still has a layer of colored steel tiles, rather than components directly used as the roof. Just like one, food is food, rice is rice, and the other is covered rice, with vegetables on it. They are sold together as a standard meal.
Reporter: then why not develop a real BIPV that can be directly used as a roof?
Qian Jing: to be a component of building materials, we need to sacrifice the surface area of the component to meet the weather resistance, safety, waterproof, ventilation, firmness and tightness of the combination mode required by the properties of building materials. At the same time, the process is special, the scale is not strong, and even sometimes it needs customization, and the cost can not come down, so BIPV has no advantage. If the traditional frameless double glass module is transformed into a standardized product, it can reflect the advantages of BIPV, that is, synchronous design and construction, in one step to avoid secondary construction and trampling.
Reporter: I saw the BIPV module of Jingke on SNEC last year. What kind of BIPV is Jingke? Can you introduce it?
Qian Jing: there are two bipvs exhibited by Jingke last year. One is curtain wall and the other is roof. The curtain wall is truly opaque BIPV, which can be directly used as power generation curtain wall or added outside the existing wall. The roof product is the atypical BIPV just mentioned. It belongs to the mainstream BIPV roof. Compared with similar products,. First, the efficiency is high. Generally, the BIPV efficiency is 14-15%, and the BIPV of Jingke is about 19%. Second, it has strong waterproof reliability. Jingke BIPV roof system mainly adopts hydrophobic frameless double glass BIPV components, main water tank and waterproof seal to form a roof waterproof and drainage system. Reliable structural glue is used to fix and seal between components without perforation connection, so as to avoid the hidden danger of water leakage. The system design also has an anti vibration system, which can effectively prevent the action of high-frequency wind load on the beach. Third, compared with traditional component installation, the cost of system support / bridge and fixed pressure block can be almost ignored, so Jingke's BIPV will have the advantage of initial installation cost. Fourth, the two in one product has clear structural stress, uniform stress and high structural safety; Of course, Jingke's black BIPV roof products are very beautiful and beautiful.
Reporter: now many industries want to enter BIPV and take a share, including photovoltaic enterprises, curtain walls, steel structures, waterproof materials, roof structures, or color steel tiles. Compared with them, what are the advantages of Jingke as a photovoltaic enterprise in BIPV?
Qian Jing: each has its own advantages. It depends on what you think of BIPV, whether it is mainly power generation, supplemented by building materials, or building materials, supplemented by power generation. If the latter, you don't need to consider BIPV, just cover the traditional components outside the traditional building materials; If building materials products that focus on power generation and pay attention to power generation efficiency, photovoltaic enterprises have advantages to lead product development, but building collaborative technology should be fully considered. This is also the advantage of atypical BIPV. This dilemma is well solved.
Reporter: what do you think of the prospect and potential of BIPV market?
Qian Jing: Industrial and commercial new roofs are the largest potential market, but this market is also challenged by traditional components. If BIPV calculates that the initial installation investment and kwh cost in Russia are less than those of traditional component applications, this product will still fail. Therefore, Jingke will continue to improve our BIPV with better efficiency and lower cost, which can be directly used as roof.
Reporter: is there any risk in the future of BIPV market?
Qian Jing: one risk is that its advantages over traditional components are not obvious. The other is that the business model is not clear, and the investment willingness of investors is not high.
Reporter: how to evaluate Tesla's solar tile?
Qian Jing: it's a good-looking product, but it's not efficient. It's suitable for residential villas, not for Industry and commerce, so the market capacity is small; The price is high. Most of the residential roofs in China are self built houses in rural areas, which does not match the consumption concept of the audience. However, the brand effect and promotion strategy are very good, which also drives China's BIPV to a certain extent.
