The world’s first fully recycled solar module has been officially launched, spearheaded by the China Green Supply Chain Alliance PV Committee, with participation from Trinasolar and multiple industry partners. This fully recycled TOPCon 210N-66 module measures 2,384 mm in height and 1,303 mm in width, achieving a conversion efficiency of 20.7% and a power output exceeding 645 W.
Trinasolar collaborated with RESOLAR to dismantle end-of-life solar modules, recovering aluminum frames, glass, silicon materials, and silver paste. These recycled materials were then processed by partners such as Yonz Technology and Flat Glass Group (FGG) to manufacture regenerated PV aluminum frames, recycled glass panels, and recycled silver paste. The module also features 100% renewable enclosures for junction boxes, lead-free ribbons, alcohol-free silicone, and a TPO thermoplastic encapsulant supplied by Sinopoly Materials, enabling easy dismantling and recycling.
Last month, Trinasolar’s Vertex N 2000V high-voltage 210 series modules earned the ‘world's first’ UL 61730 2000V certification (see China Solar PV News Snippets).
Sigenergy Technology Co., Ltd., a manufacturer of photovoltaic-storage products, has officially submitted its prospectus to the Hong Kong Stock Exchange, with the aim of a Main Board listing. CITIC Securities and BNP Paribas serve as joint sponsors for the offering.
Founded in 2022, Sigenergy focuses on the distributed energy storage sector. According to the prospectus, as of February 2025, the company’s projected annual production capacity for inverters and energy storage batteries stands at 90,000 units and 1.8 GWh, respectively. Starting with no revenues in 2022, the company reported revenues of RMB 58.3 million ($8.07 million) in 2023 and RMB 699.7 million ($96.78 million) for the first 9 months of 2024. Meanwhile, the company reported a net loss of RMB 76.19 million ($10.54 million) in 2022 and RMB 373 million ($51.61 million) in 2023. However, losses improved in 2024, narrowing to RMB 53.35 million ($7.38 million).
The prospectus highlights Sigenergy’s flagship product, SigenStor, which it claims to be the world's first AI-powered all-in-one PV-storage-charging solution. The system integrates a solar inverter, DC charger for electric vehicles, power conversion system (PCS), battery pack, and energy management system (EMS). Sigenergy claims this product accounts for over 90% of the company’s total revenue, giving it a leadership position in the global stackable all-in-one distributed energy storage system (DESS) market.
Tongwei Group’s polysilicon manufacturing subsidiary, Sichuan Yongxiang New Energy, has released a public notice soliciting opinions on the environmental impact report for its Phase II technological upgrade project in Leshan City, Sichuan Province. The project, with a total investment of RMB 400 million ($55.34 million), aims to enhance existing process parameters while adding a 10,000-ton-per-year high-purity polysilicon production line and a 10,000-ton-per-year granular silicon pilot line. Upon completion, Yongxiang’s total polysilicon production capacity will reach 101,000 tons per year, including 90,000 tons of solar-grade polysilicon, 10,000 tons of solar-grade granular silicon, and 1,000 tons of electronic-grade polysilicon.
Regarding the 10,000-ton-per-year granular silicon pilot line, local media speculates that the technology aligns with GCL Tech’s granular silicon process. However, Tongwei clarified, stating, "This granular silicon project is an R&D initiative designed to enhance the competitiveness of rod silicon. The core processes, key parameters, and quality control systems have an independent technological pathway, fundamentally differing from other industry solutions."
Tongwei recently announced that its THC 210 HJT module, measuring 2384 × 1303 mm, has achieved a power output of 783.2 W and a conversion efficiency of over 25.21% (see China Solar PV News Snippets).
Major energy developer China Huaneng has announced that it is advancing the construction of an integrated clean energy base in the Lancang River Basin, targeting a total installed capacity of 90 GW. The region currently has 32 GW of installed and under-construction hydropower capacity, with plans to integrate an additional 55 GW of new energy capacity.
Multiple ±800 kV ultra-high-voltage (UHV) transmission lines have already been established to facilitate west-to-east electricity transmission. Through a hybrid "hydro-wind-solar" approach, China Huaneng aims to enhance transmission efficiency and improve grid stability for renewable energy. The Manwan Hydro-Solar Hybrid Project in Yunnan Province, which is part of the base, serves as a model demonstration, leveraging hydropower's rapid regulation capabilities to smooth out fluctuations in solar power generation. In 2023, the project generated 276 GWh of solar electricity, equivalent to an additional 3 million m3 of daily reservoir storage.
Recently, China Huaneng formed a consortium with JA Solar and others to jointly develop a desertification control and wind-solar integrated project in Xin Barag Left Banner, Inner Mongolia (see China Solar PV News Snippets).
China Three Gorges Corporation (CTG) has announced the winners of its second batch of 2024 centralized procurement for fixed solar mounting systems. The bidding process, covering approximately 2 GW of solar projects with an estimated weight of 80,000 tons, focused solely on fixed, non-adjustable solar mounting structures, excluding adjustable and tracking products.
The 4 winning companies and their respective bid amounts are:
Arctech: RMB 474.13 million ($65.59 million)
Suzhou Lunan Fastening System Co, Ltd.: RMB 440.07 million ($60.87 million)
Jiangsu Guohua Tube Tower Manufacture Co., Ltd. (GTT): RMB 462.59 million ($63.99 million)
Suzhou Baojia New Energy Technology Co., Ltd.: RMB 468.12 million ($64.75 million)
These suppliers will provide essential structural components for CTG’s large-scale solar power projects.
