During the 14th Five-Year Plan period, China will continue to optimize the development layout of wind power and solar power generation, and give full support to the development of distributed wind power and photovoltaic while continuing to promote the construction of centralized bases. It clearly points out the following requirements: "Promoting the energy revolution", "building an ecological civilization system, promoting the overall green transformation of economic and social development", "accelerating the green and low-carbon development", and "comprehensively improving the efficiency of resource utilization", which points out the direction for the sustainable and healthy development of the energy industry. Vigorously promote the development of distributed photovoltaic power generation, which is beneficial to promote the sustained and healthy development of strategic emerging industries, to optimize the energy structure, to ensure the safety of national energy strategy, to improve the ecological environment, the transformation of the mode of urban and rural energy-using, is conducive to improve efficiency and competitiveness of solar power, electricity, conducive to the implementation of steady growth, structural adjustment, promote the reform, the livelihood policies, Foster new economic growth points.
For the photovoltaic industry, it is also of far-reaching significance. It is not only the beginning year of comprehensive parity, but also the beginning year of "carbon peak and carbon neutrality" proposed by General Secretary Xi Jinping. In recent years, China's photovoltaic industry has made full use of its technological foundation and industrial supporting advantages to develop rapidly, gradually gaining international competitive advantages and consolidating the world's most complete photovoltaic industry chain.
China pv Industry Association: China has the most complete pv industry chain in the world
In recent years, China's photovoltaic industry has made full use of its own technological foundation and industrial supporting advantages to develop rapidly, gradually gaining international competitive advantages and continuously consolidating, and has the world's most complete photovoltaic industry chain. The unique competitive advantage of China's photovoltaic industry is an important guarantee for the continuous expansion of the scale of China's photovoltaic industry, the continuous improvement of the technical level, and the continuous reduction of manufacturing costs. It is the comprehensive technological progress of China's photovoltaic industry chain that has created the brilliant achievements of China's photovoltaic industry so far.
In photovoltaic building integration, solar power generation (PV) products are combined or integrated into a building. According to the different ways of photovoltaic array and Building combination, the integration of photovoltaic Building can be divided into two categories: one is the combination of photovoltaic system and Building BAPV(Building Attached PV). Sealed, packaged pv modules are installed on the roof of a building and then connected to the power grid via inverters and controls. In this way, the photovoltaic system is attached to the building, which acts as the carrier of the photovoltaic system and plays a supporting role. The other is photovoltaic modules integrated into buildings (BIPV). In this way, photovoltaic modules appear as a building material and become an integral part of the building. This can not only develop and apply new energy, but also with decoration, beautification as a whole, to achieve energy conservation and environmental protection. This combination of BIPV, because photovoltaic modules are also part of the building, involving photovoltaic modules, so put forward higher requirements for sealant.
Photovoltaic building sealant, mainly for the application of BIPV combination form. The temperature of photovoltaic modules in the use process is higher than that of ordinary curtain wall glass, which requires that the sealant used in photovoltaic buildings must have very good high temperature resistance and can work for a long time under high temperature conditions. At the same time, the high temperature of photovoltaic modules also leads to the need for higher displacement capacity of sealant to meet the joint displacement caused by the expansion of temperature difference. Secondly, the materials that sealant needs to contact and bond in photovoltaic buildings are not only glass and aluminum, but also PPO junction box, PET/TPT/TPE battery backplane, wire and wire sheath, conductive film, film clip and so on.
This put forward very high requirements for the adhesive and compatibility of sealant. On the one hand to bond a variety of materials, on the other hand can not produce adverse physical and chemical reactions with any material. In addition, photovoltaic buildings also require sealant with good electrical insulation.
For the development of solar photovoltaic industry, Junchuan 1011 solar cell module sealant is a thixotropic single-component organic silica gel suitable for the bonding and sealing of solar cell modules. Excellent electrical insulation, high temperature resistance, water resistance, uv resistance, ozone resistance, humidity and heat aging. Good bonding performance, can maintain long-term sealing, can be suitable for different construction sites need to meet. The selection of professional and good photovoltaic rubber products can boost the new future development of photovoltaic industry.
