Two gigawatt-scale solar power plants at the Yalong River integrated hydro-wind-solar base have been commissioned. The 1 GW Suorong PV plant, located in Litang County, Garzê Tibetan Autonomous Prefecture, Sichuan Province, is a hydro-solar complementary project. The second project, the 1 GW Chabulang PV plant, is located in Muli County, Liangshan Yi Autonomous Prefecture, Sichuan.
Both projects were developed and constructed by the State Development & Investment Group (SDIC). The construction sites have an average altitude of around 4,400 meters, with Chabulang recognized as the largest ultra-high-altitude mountainous PV project in China to have entered operation to date.
With the commissioning of these 2 plants, the total operational clean energy capacity of the Yalong River integrated clean energy base now stands at 23 GW, with a further 12 GW currently under construction.
In December 2025, the Aba Rangtang Puxi II PV project, built by POWERCHINA, was connected its first 102.56 MW generation block to the grid (see China Solar PV News Snippets).
Back-contact (BC) cell and module manufacturer AIKO has announced that its ABC STELLAR 66 dual-glass module has obtained explosion-proof test certification from TÜV SÜD. The company claims it is the world’s first BC module to receive this certification.
AIKO stated that the module complies with the GB 3836.3 standard and leverages its cell architecture and copper interconnection design to ensure long-term electrical stability under mechanical stress and harsh operating conditions. The company further highlighted that BC modules' inherent resistance to hotspot risks enhances safety and system stability in flammable, explosive, and other extreme application environments.
Last month, AIKO announced that Ruijing Energy (Beihai) Co., Ltd., a subsidiary established by AIKO and Skyworth’s joint venture in Beihai, Guangxi Province, is advancing construction of its 5 GW high-efficiency BC module R&D and manufacturing base (see China Solar PV News Snippets).
China’s National Intellectual Property Administration (CNIPA) and the Ministry of Industry and Information Technology (MIIT) have jointly released a document titled ‘Opinions on Further Strengthening Intellectual Property Protection in the Photovoltaic Industry.’ The document aims to achieve tangible progress in using intellectual property (IP) protection to support healthy development in the PV sector by 2027.
Key measures include establishing an IP infringement risk monitoring mechanism from upstream raw material processing to module manufacturing; legally prohibiting the import and export of PV products that infringe IP rights; and requiring state-owned enterprises to take administrative rulings or effective court judgments on IP infringement as key references in procurement and tendering processes, in order to prevent the manufacture, sale, and use of infringing PV products.
Solar module and backsheet manufacturer Jolywood announced that its subsidiary, Taizhou Jolywood, has secured a PV module supply contract from Ganzi Xiangcheng Zhexineng Photovoltaic Power Generation Co., Ltd. Under the contract, Jolywood will supply a total of 207.57 MW of n-type PV modules for the Ganzi Xiangcheng Gongzha Phase II solar power project. The total contract value is RMB 154.12 million.
In October 2025, Jolywood revealed plans to gradually upgrade part of its 16 GW TOPCon cell factory in Shanxi province to produce back-contact cells (see China Solar PV News Snippets).
DintoSolar, a subsidiary of State Power Investment Corporation (SPIC), has delivered 200 MW of heterojunction (HJT) modules to China Huadian’s Shandong subsidiary. The modules, with rated power of 715 W and 720 W, will be used in China Huadian’s distributed rooftop PV projects in Shandong Province.
DintoSolar stated that it has planned to expand its HJT cell and module production capacity to 15 GW annually, and has already achieved the application of silver-free technology in mass production.
