Trinasolar’s energy storage arm Trina Storage has released a white paper that explores innovations in energy storage cells, emphasizing extended cycle life, high performance, and enhanced safety. It highlights the industry's shift toward large-capacity, long-lifespan cells to deliver scalable, cost-effective solutions, alongside material advancements in electrolytes, separators, and structural designs to boost safety and efficiency. The paper also underscores the importance of rigorous testing and adherence to international safety standards, ensuring reliability in modern energy systems.
In December 2024, Trina Storage collaborated with TÜV NORD to publish a detailed white paper addressing safety and reliability in energy storage systems (see China Solar PV News Snippets).
Leading polysilicon supplier GCL Technology has released a report listing its achievements in 2024. The company produced 269,200 tons and shipped 281,900 tons of granular silicon in 2024. The average production cash cost for the year was RMB 33.52/kg, with the Q4 cost reduced to RMB 28.17/kg. GCL Tech also fully exited investments related to Siemens process polysilicon, focusing exclusively on developing its granular silicon business.
In September 2024, the GCL Group company announced that the granular silicon produced at its Leshan base received carbon footprint certification ADEME (see China Solar PV News Snippets).
The bid results for the first phase of the 3 GW (AC) Hongsibao Renewable Energy Base Solar project by Hunan Energy Group have been announced. Phase 1 of the procurement includes 1.2 GW of bifacial double-glass n-type modules with a power output of 615 Wp or higher. LONGi secured the top spot as the preferred bidder with a bid price of RMB 0.705/W ($0.097/W). JA Solar and Tongwei Solar were named the second and third preferred bidders, with bid prices of RMB 0.705/W ($0.097/W) and RMB 0.699/W ($0.096/W), respectively.
Perovskite solar cell manufacturer Renshine Solar, in collaboration with Nanjing University, has published its latest research in the field of all-perovskite tandem solar cells in Nature Materials. The paper, titled All-perovskite tandem solar cells achieving >29% efficiency with improved (100)-orientation in wide-bandgap perovskites, details the development of a wide-bandgap perovskite film with enhanced (100)-orientation, which suppresses non-radiative recombination. The resulting wide-bandgap (1.78 eV) perovskite solar cells achieved an open-circuit voltage of 1.373 V and a fill factor of 84.7%. The certified power conversion efficiency of the all-perovskite tandem solar cell was 29.1%, with an open-circuit voltage of 2.21 V under maximum power point conditions.
Late last year, RenShine’s single-junction perovskite solar module, measuring 1.2 x 0.6 m with a total area of 0.72 m2, achieved a conversion efficiency of 19.27% (see China Solar PV News Snippets).
Solar tracker manufacturer Arctech Solar has reported its preliminary results for FY2024. The company’s net profit of approximately RMB 635 million ($89.34 million) for 2024 was an increase of 84.04% year-on-year (YoY). Arctech attributes its strong performance to robust global solar market growth and rising demand for ground-mounted solar systems overseas. As of December 31, 2024, the company held orders worth RMB 4.65 billion ($638.88 million), including RMB 3.5 billion ($480.88 million) for tracking systems and RMB 1.15 billion ($158 million) for other products.
In November 2024, Artech Solar expanded its business scope to include the integration of energy storage systems, charging and swapping systems, smart cleaning robots and accessories, new building materials, and lightweight construction materials (see China Solar PV News Snippets).
