Suntech Group showed up with all members at SNEC 2020
2020-08-08

On August 8th, 2020, the 14th International Photovoltaic Power Generation and Smart Energy Conference & Exhibition (SNEC) was opened in SHANGHAI New International Expo Centre. All companies from Suntech Group attended the exhibition together. Wuxi Suntech Power Co., Ltd., Jiangsu Shunfeng Photovoltaic Technology Co., Ltd., and Rietech New Energy Science & Technology Co., Ltd. exhibited a variety of new products, demonstrating the advantages of vertical integration in a group and introducing a new brand concept to connect the entire industry chain.

 

Wuxi Suntech Power Co., Ltd.

Since its establishment in 2001, Suntech has experienced twenty years of development and achieved great success in the renewable energy industry. Suntech has been developing with good momentum these years. Supported by an excellent global brand reputation, overseas shipments have increased year by year and reached new records. As of 2020 Q1, Suntech has a cumulative shipment of more than 22GW of PV modules to 100 countries, ranked top 10 among all brands in the solar energy sector globally. On August 1st, Suntech announced that the 1.5GW high-efficiency module expansion in the Wuxi module manufacturing facility was officially put into production. With a total investment of 490 million RMB, the new 1.5GW high-standard smart module manufacturing facility which covers an area of 150,000 square meters has been set up. The newly installed equipment will improve the production efficiency for modules. At present, Suntech’s new production line has covered all mainstream technologies for products in the market. It is compatible with multi-busbar cells of various formats from 166mm to 182mm, fitting 78-cell solar modules, as well as the upgrade space for 210mm large format cells. Suntech will keep upgrading the Wuxi manufacturing facility with intelligent technology later this year, and is committed to creating a national pilot demonstration project of intelligent manufacturing and a national project of intelligent manufacturing with comprehensive standardization and application of new modes, which will enable the Wuxi manufacturing facility to achieve AI intelligent inspection and IV automatic testing as well as other technological improvements.

 

Suntech is always devoted to promoting conversion efficiency of PV products. With the fierce competition in the industry, while continuously pursuing the reduction of module costs, it puts more and more effort in R&D of new technologies and the improvement of production processes. By virtue of the state-of-the-art technical advantages and the excellent manufacturing level, Suntech launched a new generation of modules of ultra-high power--- the “Ultra” series at this exhibition. Being named as “Ultra”, the new generation represents the “supreme”, demonstrating Suntech’s ultimate ingenuity in keeping up with the development of the times. The series includes module products of various formats silicon cells like 166/182/210mm, with the highest power exceeding 605W+. Equipped with mature technologies such as half-cut cell, multi-busbar, bifacial, high-density cell interconnect technology and high-efficiency welding strip technologies, Suntech has a particularly optimized structure design and owns the exclusive patent that while guaranteeing the super mechanical load capacity of products, the products can still be light, with the weight over 22.3% lower than that of mainstream products of the same specifications in the market. Suntech adheres to the idea of human-friendly design, and has optimized the module in size, weight and system compatibility to achieve higher matching performance for terminals, lower LCOE, and more benefits to customers.

 

Jiangsu Shunfeng Photovoltaic Technology Co., Ltd.

Founded in 2005, Shunfeng Photovoltaic is a high-tech enterprise focusing on R&D, production and sales of high-performance solar cells. In 2018, Shunfeng Photovoltaic invested in a capacity expansion for high-efficiency solar cells with a production capacity of 1.5GW. The annual production capacity reached 3GW, among which the production capacity of high-efficiency monocrystalline PERC, P-type bifacial PERC, and N-TOPCon have altogether reached 2GW. The production line is capable of producing cells of various sizes such as 156mm, 158mm, 166mm, 18Xmm, etc. Shunfeng Photovoltaic has a good reputation in the industry in terms of high conversion efficiency and high reliability. Ahead of the whole industry, the company is the first to implement 100% visual inspection and EL testing, which can achieve zero micro crack loss in cells. In addition, its cell products have passed double PID (potential induced degradation) testing and reliability testing which guarantees 25 years’ power output of modules. Shunfeng Photovoltaic’s professional equipment can realize precise color separation and Shunfeng Photovoltaic itself is the preferred cell brand for black modules in the industry. For 15 years, Shunfeng Photovoltaic has promoted the application of high-efficiency cell technology in the global PV market by virtue of its high-efficiency products and high-quality services, creating more value for global customers.

 

In this exhibition, Shunfeng Photovoltaic presented four types of high-efficiency solar cell products, two of which are 158mm size monocrystalline PERC and 166mm size monocrystalline PERC bifacial cells developed on the base of a PERC technology platform. Shunfeng Photovoltaic’s conventional monocrystalline PERC cells are optimized through diffusion, SE, and metallization processes. The current mainstream conversion efficiency for mass production can reach 22.8%. Combining the half-cell and MBB design, 166mm size cells can meet the needs of 460W high-power modules. As for bifacial PERC cells, through changing the cell structure, its front conversion efficiency reaches 22.8% and its bifacial ability exceeds 75%. With the help of double-glass modules, the generated power can increase by 5%-10%. The average conversion efficiency of polycrystalline solar cells can reach up to 19%, which can meet the requirements of packaging 280W modules. The new N-TOPCon cell currently has a front conversion efficiency of 24.1% and bifacial ability exceeds 90%, demonstrating outstanding advantages such as high cost performance and no LID (Light Induced Degradation).

 

Rietech New Energy Science & Technology Co., Ltd.

Established in June 2007, Rietech New Energy is a national key high-tech enterprise focusing on the R&D and production of solar grade multi wafers. The company adheres to the business philosophy of “increasing value for customers in upstream and downstream supply chains”, with a total investment of more than 5 billion yuan. The two R&D and production factories are located in Yangzhong Economic Development Zone in Zhenjiang City and Yangzhou Integrated Free Trade Zone. Rietech attaches great importance to the R&D of key technologies for silicon wafers for solar cells, and has made major breakthroughs in core equipment, advanced production technology, and frontier technologies. It is the first enterprise in the industry to conduct R&D of quasi-mono silicon wafer technology, introducing a diamond wire cutting machine, and having realized R&D and mass production of poly full-melt technology.

 

At this exhibition, Rietech exhibited a variety of silicon wafer products. As for Reitech R3 high-efficiency polysilicon wafers, Rietech R&D platform ensures the continuous improvement of wafer performance. Rietech has been focusing on a full-melt casting process which ensures low oxygen content in silicon wafers and avoids black edges. The mature co-doping technology ensures narrower resistivity distribution and more cell efficiency gain for PERC processes. As for the Rietech Medium Efficiency Multi Wafer, the efficiency is higher than 19% while LID is lower than 0.8%. In addition, Rietech launched its new generation of Cast Mono wafers in the exhibition, which has advantages of low dislocation density, low oxygen content, and an all size (158.75/166/167.75/182/210mm) manufacture ability. N type Cast Mono wafers with 145μm thickness and customized resistivity range are also available.

 

In 2020, Suntech Group has started the projects of 5GW and 2GW module production in Yangzhou and Zhenjiang respectively. The projects improved the cooperation between all members and highlighted the advantages of the group’s vertical integration through the collaboration of each company’s management, technology, capital, channel, and brand. This lead to a higher quality of group development. The realization of the target production capacity at the end of 2020 will further satisfy the global photovoltaic (PV) market’s demand for high-quality, high-reliability PV modules, thus enhancing the competitiveness of Suntech modules in domestic and foreign markets.
