China’s Ministry of Industry and Information Technology (MIIT) has initiated a special energy conservation supervision campaign for the polysilicon sector in 2025. The campaign will inspect polysilicon manufacturers based on mandatory national energy consumption limits, energy efficiency standards, as well as benchmark and baseline levels. A total of 41 companies will be inspected as part of this exercise, including industry leaders such as Tongwei Group’s Sichuan Yongxiang, Daqo New Energy, and GCL. It will focus on core industrial equipment, and companies with inefficient equipment that fail to meet mandatory efficiency thresholds will be required to rectify the issue by law. Non-compliant firms or those failing to rectify in time will face regulatory actions in accordance with relevant laws and regulations.
Last month, China’s State Administration for Market Regulation and the Ministry of Industry and Information Technology (MIIT) jointly released an action plan for the PV industry with a focus on developing key metrology technologies (see China Solar PV News Snippets).
PV mounting system manufacturer VG Solar is planning to build a new production facility with an annual output capacity of 4 GW for solar tracking systems. The plant will be located in Jiaxing, Zhejiang Province, with a total investment of RMB 400 million ($55.56 million). The facility will be spread over 28,119 m2 and is designed to produce 80,000 sets of solar tracking brackets annually. The company has already submitted environmental assessment and construction application documents to the local government.
Leading PV and ESS supplier JinkoSolar has announced that it is accelerating the mass production of its high-power TOPCon solar modules above 640 W. During a recent roadshow, the company said its Shangrao and Shanxi facilities have completed capacity upgrades. The company expects 640 W+ products to account for 40% to 50% of its total production capacity. In 2026, most capacity will support mainstream modules rated at 650 W to 670 W. The company has already started partial deliveries of modules over 640 W in Q3 this year, and anticipates that most orders next year will shift to these high-power models. JinkoSolar expects its advanced production lines to reach approximately 670 W next year and potentially achieve 680 W to 700 W in the next 2 to 3 years.
Earlier this month, JinkoSolar announced that cumulative shipments of its Tiger Neo series TOPCon module series have surpassed 200 GW. At SNEC 2025, JinkoSolar showcased its Tiger Neo 3.0 series module, rated at 670 W power and 24.8% efficiency (see JinkoSolar Unveils Tiger Neo 3.0 Module At SNEC 2025).
Leading energy developer China Huaneng is developing an integrated energy base that combines coal-fired power with renewable energy in Shanxi Province. According to local media, the project – located in Shuozhou City – is taking in a total investment of over RMB 30 billion ($4.17 billion) and a planned capacity of over 6 GW. Construction of the 2×1 GW ultra-supercritical air-cooled coal power units began at the end of July. The base also includes a planned 4 GW of renewable energy capacity. Once fully operational by 2028, the project aims to integrate coal and renewable sources for optimized grid dispatch, with clean energy expected to account for about 50% of total output.
Recently, the ‘world’s first’ international standard in the field of PV DC systems, titled IEC TR 63534 ED1:2025 - Distributed Photovoltaic Access to Low Voltage Direct Current Systems and Use Cases, was published (see China Solar PV News Snippets).
According to the latest data from the National Energy Administration (NEA), China issued a total of 278 million green electricity certificates (GECs) in June 2025, up 29.33% from May. These were issued to 198,700 renewable energy projects, including 6,994 solar PV projects and 11,078 wind power projects. From January to June, the NEA issued a cumulative 1.371 billion GECs, with 27,964 certificates for solar and 57,630 for wind.
On the trading side, 60.91 million GECs were transacted nationwide in June, including 23.64 million from solar and 29.27 million from wind. In total, 348 million GECs were traded in the first half of the year, including 144.58 million for solar and 176.21 million for wind.
Earlier this year, China’s NDRC, NEA, along with 4 other government departments, jointly issued guidelines to establish a high-quality GEC market and facilitate the rational pricing of GECs to reflect the environmental value of green electricity (see China Solar PV News Snippets).
