[Tianchang—report to you! ] Helping carbon peak to achieve carbon neutrality——Tianda New Energy

Helping to achieve carbon neutrality ——Tianda New Energy Tianda Group is a manufacturing-oriented industrial company founded in 1975. After nearly 50 years of steady development, it has formed the leading industries of biomedicine, plastic materials, precision copper, composite aluminum and photovoltaic modules. Under the group, there are subsidiaries such as General Biology, Tianda Environmental Protection, Tianda Petrochemical, Tianda Copper, Tianda Aluminum and Tianda New Energy. Tianda Group achieved sales revenue of 27.395 billion yuan in 2021 and was selected as one of the top 500 private enterprises in China and one of the top 500 manufacturing enterprises in China. 1678792024258605.png Tianda Group originated in Tianchang and has its roots in Tianchang. In recent years, after Tianda Copper 250,000 tons of precision copper processing project and Tianda Petrochemical 300,000 tons of polypropylene project started operation, Tianda New Energy was born to meet the national goal of achieving double carbon. Tianda New Energy is located in Chuzhou High-tech Zone, Tianchang City, focusing on the research and development, production and sales of photovoltaic modules and photovoltaic power generation systems. The first phase of the PV module production project covers an area of nearly 230 mu, which will be put into operation while under construction, and is expected to achieve 5GW annual production capacity and mass production in 2023. 1678792045313694.png Tianda New Energy introduces professional talents in R&D, production, technology and sales from head enterprises in the industry, uses international advanced automatic production lines and high-end equipment, and uses large-size high-efficiency cells such as 182mm and 210mm as a guide for mainstream market demand, providing mainstream specification products to meet various application scenarios, with several technical advantages: 1. Half-sheet technology: With half-sheet cell technology, it not only has higher conversion efficiency, but also has lower rated operating temperature (NOCT). Compared with the full-cell module, the working temperature of half-cell module is 2-3℃ lower, while its hot spot temperature is 10-20℃ lower than the full-cell module. In addition, half-cell modules also have lower shadow shading loss. 2. Multi-grid technology: With MBB cell technology, the conversion efficiency of the cell can be improved, and at the same time, the impact of broken grids and hidden cracks on the module performance is reduced. The cell is designed with circular weld strips, and the IAM performance is better than conventional flat weld strips when the light is obliquely incident. And more main grids with smaller diameter round tape design, can reduce the impact of stress, can effectively improve the module's high and low temperature resistance and mechanical load performance. 3. White EVA application technology: The use of white EVA for the lower encapsulation material of the module can effectively improve the reflection of the cell spacing and string spacing light in the module, thus enhancing the sunlight utilization and increasing the module power. In general, the relative conversion efficiency of single-glass module with white EVA can be increased by 0.5%-0.7%, and the relative conversion efficiency of double-glass module with white EVA can be increased by about 1%-1.2%. In addition, white EVA can also effectively block ultraviolet rays and play a protective role for the backplane, thus improving the reliability of the formation. 4. plate interconnection technology: plate interconnection components, also known as high-density components, through innovative design ideas, on the basis of conventional processes, the gap between the component cells compressed to the extreme, to achieve efficient use of space components, and at the same time, through the improvement of the use of the battery, more optimized components working temperature, improve the ability to resist hot spots, so that the components have high conversion efficiency, high reliability and other superior features. The development of PV modules is a continuous process of pursuing manufacturing cost reduction, efficiency and efficiency, while continuing to work hard for customers' power generation revenue improvement, and improving performance indicators has reached a bottleneck, from "string" to "plate", from "This is the inevitable trend of development. 5. non-destructive cutting: Compared with the traditional laser melting cutting, non-destructive cutting uses continuous laser to heat the cell and assisted by atomization cooling, forming a temperature gradient which causes thermal stress leading to cracking of the cell. This cutting method can not only effectively reduce the micro-crack at the cell cutting mouth, enhance the parallel resistance of the cell, effectively reduce the leakage current, and the cutting surface is very smooth, and the mechanical strength of the cut cell is close to that of the uncut cell. 6. Other optimization technologies: The following optimization of module process and materials improve the conversion efficiency and reliability of the module. Adopt high-transmission glass to increase the light transmission rate and improve the weather resistance of the module. Optimize adhesive film and backsheet to improve module power and reliability. Optimize cell cutting process to reduce laser damage and improve product reliability. Select TOPCon cells to improve module conversion efficiency. Optional innovative rail bezel design for smaller module weight, easier installation and better mechanical load performance. 1678792069288476.png In addition to the production and sales of high-efficiency PV modules with leading technology and reliable quality, backed by the qualification, strength and integrity of Tianda Group, Tianda Green Power, a subsidiary of Tianda New Energy, has built a skilled and experienced rooftop PV power plant design, installation, operation and maintenance team to provide reliable one-stop services and system solutions for industrial and commercial customers, such as general contract construction and full investment operation and maintenance. We use Tianda New Energy's high-efficiency photovoltaic module products, intelligent and digital engineering implementation capabilities, and whole-life operation and maintenance to ensure that owners and users share high returns steadily and continuously while using green and clean energy. At present, Tianda Green Power has started various forms of cooperation with many industrial and commercial enterprises in the city, and is expanding and promoting to the provincial, national and global markets. 1678792084640180.png On April 19, 2021, China's National Energy Administration "Notice on Matters Relating to the Development and Construction of Wind Power and Photovoltaic Power Generation in 2021 (Draft for Comments)" pointed out that: "In-depth implementation of General Secretary Xi Jinping's important remarks on the new strategy of energy security, the implementation of carbon peak, carbon neutral goals, as well as 2030 non-fossil energy accounted for about 25% of primary energy consumption, the total installed capacity of wind and solar power generation reached more than 1.2 billion kilowatts and other tasks ......", to achieve carbon neutral goals by 2060, photovoltaic wind power has the greatest potential, followed by nuclear power. 1678792113280034.png Looking into the future, Tianda New Energy will enter the new energy sector with photovoltaic modules as the entry point, and will start various forms of cooperation with professional enterprises in the photovoltaic industry chain and innovative companies in the new energy field with pragmatic innovation and win-win cooperation, continuously expand the diversified scale application scenarios of photovoltaic technology, actively investigate and intend to layout photovoltaic building integration, photovoltaic hydrogen production, energy storage and other fields to build a new energy ecosystem faster and better. 1678792131480705.png Tianda New Energy adheres to the development strategy of "Specialization, Excellence and Internationalization", carries forward the enterprise spirit of "Virtue and Integrity, Dedication and Excellence", adheres to the business philosophy of "Customer First, Practical Work and Innovation", devotes to the production and supply of zero carbon emission photovoltaic clean energy, promotes the green and low carbon development of the region's economy and the transformation of energy structure, helps to achieve the goal of "Double Carbon", and makes Tianda's due contribution to the living environment of human beings and the economic development of the region! 1678792147411124-min.png
