High-Voltage, High-Power Inverters & Medium-to-High-Power Energy Storage Inverters: A combined investment of RMB 632 million ($86.58 million) will expand inverter production capacity to meet the demands of large-scale ground-mounted power stations and the commercial and industrial energy storage market
Shanghai R&D Center: An investment of RMB 250 million ($34.25 million) will establish a high-level laboratory to drive innovation in energy storage technologies
In November 2024, Solis received the First Prize for Scientific and Technological Progress in Electric Power in the 2024 China Electric Power Science and Technology Awards (see China Solar PV News Snippets).
Tandem solar cell maker HIKING PV has commenced construction on a 250 MW perovskite tandem cell manufacturing fab. Located in Zhongshan City, Guangdong Province, the project boasts a total investment of RMB 10 billion ($1,369.86 million) to establish a 250 MW TOPCon/perovskite tandem cell production line. In January 2024, HIKING PV signed an agreement with Zhongshan Investment Holding Group Co., Ltd. and Zhongshan Torch Industrial Group to develop an integrated R&D and manufacturing base in Zhongshan focused on a 7 GW perovskite/crystalline silicon tandem cell and module facility, which was planned to be slated to be implemented in three phases, with a total planned investment of RMB 50 billion ($6.85 billion).
In June 2024, Hiking PV announced that it had completed the development of tandem cells from small size (1 cm²) to full size (see China Solar PV News Snippets).
Taian JinenU Solar, a holding subsidiary of JinenU Solar, has filed a lawsuit with the Wuxi Intermediate People’s Court against SUNTECH, its parent company SF-PV, and China Orient Asset Management (International) Holdings Limited over a dispute concerning the creditor’s right of rescission. The case is scheduled to be heard in March 2025. In December 2023, JinenU Solar founder Fei Wu assumed the position of chairman of SUNTECH; by the end of 2024, Wu Fei announced his resignation from the role, indirectly confirming that SUNTECH has been placed under trusteeship by Xiamen Jianfa Group. According to the timeline, Wu Fei initiated litigation against SUNTECH shortly after stepping down.
In addition to this lawsuit with JinenU Solar, SUNTECH and SF-PV are defendants in several other litigation cases, with plaintiffs including solar equipment manufacturer Autoway, ribbon manufacturer YourBuddy, and encapsulant material maker SVECK, among others.
Leading US-based electric vehicle and energy storage manufacturer Tesla’s Shanghai-based energy storage super factory held a commissioning ceremony, during which the first ultra-large commercial electrochemical energy storage system (ESS) Megapack successfully rolled off the production line. This is Tesla’s first energy storage super factory outside its domestic market. Covering an area of approximately 200,000 m2, the facility is planned to have an annual production capacity of 10,000 Megapack systems, with ramp-up scheduled to begin in the first quarter of 2025. Once fully operational, the factory will be capable of producing nearly 40 GWh of Megapack energy storage systems per year. Its products are intended for global distribution, which will help alleviate worldwide supply constraints for Tesla’s Megapack systems.
