GCL Technology announced that its production facility in Baotou, Inner Mongolia, has received certification from the French Environment and Energy Management Agency (ADEME) for its granular silicon product, with a verified carbon footprint of 14.441 kgCO₂e/kg.
The company states this new record marks a 42% reduction from the 24.913 kgCO₂e/kg value certified for its Leshan facility in August 2024. GCL Tech attributed this reduction to its proprietary silane fluidized bed technology, which enables low energy consumption and high yield while eliminating the need for ingot crushing, thus offering a disruptive advantage over traditional ingot-based silicon processes.
Recently, as part of its Q1 2025 unaudited results, GCL Tech reported strong profit margins for its granular silicon product (see China Solar PV News Snippets).
ABC cell and module manufacturer AIKO has signed an investment agreement with Skyworth PV and the government of Baise City, Guangxi, to establish a joint venture (JV). The new entity will develop the Skyworth-AIKO (Baise) Southwest ABC Cell Manufacturing Base. The new JV will be established with a registered capital of RMB 1 billion ($137 million). Skyworth PV, through a subsidiary, will hold 55%, AIKO will hold 25%, and the remaining 20% will be held by the Baise municipal government or a designated state-owned investment company.
AIKO will provide the JV with a comprehensive technical consulting service package, including production line setup, commissioning, and process optimization for a total service fee of RMB 200 million ($27.40 million).
According to local media outlet Youjiang Daily, Baise City is advancing a 5 GW BC cell factory with a total planned investment of RMB 4.1 billion ($561.64 million), expected to enter production in the second half of 2025.
JinkoSolar’s storage arm, Jinko ESS, has launched its new-generation SunTera G3 6.25 MWh energy storage system (ESS), with global deliveries scheduled to begin in Q4 2025.
SunTera G3 features a 6.251 MWh rated capacity, over 10,000 cycles, and more than 95% round-trip efficiency, significantly improving energy output over its lifecycle. The company has equipped the system with IP55 ingress protection, C5 anti-corrosion rating, and is capable of operating at altitudes up to 4,000 meters, making it suitable for extreme environments.
Earlier this year, Jinko ESS maintained its spot on BloombergNEF’s (BNEF) Tier 1 Energy Storage Provider List for Q1 2025 (see China Solar PV News Snippets).
Solar cell and module manufacturer DAS Solar will undergo a change in controlling shareholder. Quzhou Industrial Holding Group Co., Ltd., a state-owned real estate development enterprise in Quzhou, Zhejiang Province, will become the controlling shareholder through a 17.46% equity acquisition via its subsidiary.
Following the transaction, Quzhou Industrial plans to enter into a voting rights entrustment agreement with DAS Solar Chairman Yong Liu and his concerted parties. Before the transaction, Yong Liu controlled 29.03% of voting rights. After the deal, Quzhou Industrial Holding will control a minimum 34.05% of voting rights, thereby becoming the actual controller of DAS Solar.
Microinverter and energy storage manufacturer Hoymiles has introduced 2 new products: the HoyUltra 2 C&I liquid-cooled storage system and the HPCS2500 grid-forming converter.
HoyUltra 2 features 90.3% round-trip efficiency and over 88.4% equivalent cycle efficiency. Using next-gen 314 Ah cells, it achieves a 21.4% increase in energy density. With Hoymiles’ proprietary EMS, it supports cloud-edge control, automatic islanding, and boasts over 99% system availability.
The HPCS2500, built for grid-scale applications, offers 1.5x 10-second overload and stable performance in grids with SCR as low as 1.0. Its ‘liquid cooling + top air exhaust’ design enhances thermal management. With a footprint of just 1.4 m², it delivers 45% higher power density than its predecessor.
