While the reliability of PV modules remains a non-negotiable priority for the solar industry, testing organizations do report quality challenges. Modules produced in 2025 are expected to perform in the field for decades, and every design and material decision can have a lasting impact on performance and resilience. Ensuring that innovations in efficiency and cost reduction are matched by equal attention to reliability is essential for maintaining the industry’s credibility.
The TaiyangNews Virtual Conference on Reliable PV Module Design brings together experts to discuss how reliable PV module design and mass production can be achieved amid the pressures of rapid innovation and significant costs. Scheduled for Thursday, November 6, 2025,
Xinrui An, R&D Manager at JTPV, will be speaking on the topic Jietai Solar: Bringing Reliability and Efficiency to PV Modules at the event.
Registration for the event is free and can be done here.
According to the Economic and Information Technology Bureau of Longyou County, Quzhou City, Zhejiang Province, Zhejiang Xinruiteng Intelligent Technology Co., Ltd. has filed to build a factory capable of producing 50 sets of perovskite production equipment annually. The company, established in September 2025 and wholly owned by Hong Kong-based Shengji Ltd., plans to invest $21.11 million in equipment, such as slot-die coating and ALD systems. Construction is scheduled to begin in November 2025 with a completion target of January 2026.
GCL SI, the solar cell and module manufacturing arm of the GCL Group, announced it is voluntarily cancelling its planned private-placement fundraising of up to RMB 4.842 billion ($681 million). This fundraising effort aimed to support the expansion of high-efficiency cell manufacturing capacity to 10 GW in Wuhu, Anhui Province, as well as working capital needs. The company cited the current PV industry’s cyclical and structural adjustment environment as the reason for termination.
Meanwhile, in its Q3 2025 results, GCL SI reported revenues of RMB 4.00 billion ($562.07 million), an increase of 3.12% year-over-year (YoY). However, the company reported a net loss (excl. non-recurring items) of RMB 235.03 million ($33.08 million) for the quarter, compared to a profit of RMB 22.48 million ($3.16 million) in Q3 last year.
Leading solar manufacturer LONGi’s Hi-MO X10 lightweight PV module has received Grade AAA certification from TÜV Rheinland, based on standard 2PfG 2992/08.24 designed for lightweight PV modules (flexible, semi-rigid, and rigid structures). Grade AAA represents the highest level in the certification, intended for high-reliability projects. LONGi states that the Hi-MO X10 lightweight module utilizes its HPBC 2.0 technology, achieving a power output of up to 560 W and a conversion efficiency of 24.8%. With a weight of 7.2 kg/m2, it is promoted for low-load rooftops such as old factory buildings, lightweight steel roofs, and grid-frame structures.
Last month, LONGi’s Hi-MO X10 ‘Triple Protection’ module received joint validation from CPVT, TÜV Rheinland, and CGC (see China Solar PV News Snippets).
Tongwei Co., Ltd., the parent of Tongwei Solar, announced Q3 2025 revenues of RMB 24.09 billion ($3.39 billion), roughly flat YoY. While revenue held steady, losses narrowed sharply: net loss (excl. non-recurring items) dropped from RMB 859.16 million ($120.78 million) in Q3 2024 to RMB 442.23 million ($62.17 million) in Q3 2025.
For the first 9 months, the company recorded revenues of RMB 64.60 billion ($9.09 billion), down 5.38% YoY. Its net loss (excl. non-recurring items) for the period totaled RMB 5.47 billion ($770 million), down 35.5% YoY.
In September, Tongwei Solar’s Meishan plant was added to the Global Lighthouse Network 2025 (see China Solar PV News Snippets).
