Xinrui An, R&D Manager at Jietai Solar (JTPV), will be presenting on the topic titled Advancing n-Type Module Power to 650 W and Beyond on Day 3 of the TaiyangNews High-Efficiency Solar Technologies 2025 Conference. The Conference will focus on TOPCon technology on December 9, 2025, followed by Heterojunction on December 10, 2025.
Join us to hear from global leaders shaping the future of high-efficiency PV and the next leap in solar manufacturing.

GCL System Integration (GCL SI), the solar cell and module manufacturing arm of GCL Group, is planning to upgrade one of its TOPCon cell lines to support back-contact (BC) cell production.
According to a recently published environmental assessment, GCL SI operates 10 GW of high-efficiency TOPCon cell capacity at its Wuhu facility in Anhui Province. The company intends to retrofit 2 GW of this capacity by introducing processes such as laser film-opening. After the upgrade, the line will produce GCL SI’s GPC cells based on BC technology, which will use the company’s patterned precision-doping passivated contact technology.
In October, GCL SI cancelled its planned private-placement fundraising of up to RMB 4.842 billion (see China Solar PV News Snippets).
Huizhou Tanhe New Energy Management Technology Co., Ltd., a subsidiary of TCL Solar, has completed registration of its first green directed asset-backed note (ABN) with the National Association of Financial Market Institutional Investors (NAFMII), with a total approved quota of RMB 500 million. The first tranche amounts to RMB 187 million.
The ABN is backed by high-quality C&I distributed PV assets under TCL Solar. The proceeds from the issuance will be used for the construction of new PV plants, O&M upgrades of existing projects, expansion of new production capacity, and technology R&D.
Earlier this year, TCL Solar, together with a Zhongrong Group subsidiary, brought online the Yangjiang Yichuan 125 MW/250 MWh user-side energy storage power station (see China Solar PV News Snippets).
Huawei Digital Power, a subsidiary of Huawei, announced that it has completed a fire test for its grid-forming, liquid-cooled C&I energy storage solution, witnessed by TÜV Rheinland and conducted in accordance with the latest UL9540A:2025 standard.
The test triggered thermal runaway in 60 cells simultaneously via full-pack overcharging. Following the open-door combustion method defined in UL9540A:2025, the test maximized oxygen supply, with all battery packs charged to 100% SOC.
Results showed that even when the fire zone reached 961°C, the highest cell temperature in adjacent cabinets was only 45.3°C, far below the cell venting threshold. The recorded peak heat release rate (HRR) was 3 MW, no cross-cabinet propagation occurred, and the fire self-extinguished in under 3 hours.
The Guizhou Provincial Energy Administration has released a draft for public comment on the management measures for solar PV and wind projects.
The draft requires provincial authorities to set annual construction plans for centralized wind and solar projects based on development targets and grid absorption capacity. It mandates that PV projects must adopt advanced technologies and use modules with a minimum conversion efficiency of 22.3%.
The document also calls for maximizing the use of low-value land such as landfills and subsidence areas, while promoting PV-plus-agriculture, PV-plus-forestry, and PV-plus-tea plantation models. Additionally, it encourages equipment upgrades for PV projects that have been in operation for eight years or longer.
