Leading integrated PV manufacturer Tongwei’s Photovoltaic Technology Center has announced that its THC-G12 heterojunction (HJT) module has achieved a TÜV-verified maximum power output of 790.8 W. Tongwei says that this is its 11th HJT power record since 2023, surpassing its recent record of 783.2 W in February 2024 record (see China Solar PV News Snippets).
According to Tongwei, this breakthrough was achieved through advanced rear passivation, edge optimization, and fine-line technology at the cell level. At the module level, innovations such as Tongwei's 908 0BB interconnection technology, ultra-high flux light utilization, and ultra-low loss wire transmission contributed to achieving a full-area module efficiency of 25.46%, which is said to be the highest third-party verified efficiency for crystalline silicon modules.
Solar and lithium battery equipment manufacturer LEAD announced that it has won an order for high-efficiency back-contact (BC) module production line equipment from a leading PV company. The order includes screen-printing equipment, BC cell stringer, and related products. The company reported that its cumulative BC equipment shipments have now exceeded 30 GW.
LEAD highlighted that its new busbar shaping process for BC module string welding machines effectively resolves cell warping issues after single-sided welding. Additionally, its new welding technology replaces traditional infrared welding, reducing energy consumption by over 50%.
Last month, LEAD Group subsidiary Leadmicro announced that it had shipped its new independently-developed Edge Passivation 2.0 equipment for validation at a customer site (see China Solar PV News Snippets).
Global solar and energy storage solutions provider Trinasolar has signed an ESG-linked loan agreement with Industrial Bank. The company says this is China's first loan with interest rate incentives tied to environmental, social, and governance (ESG) performance. According to the agreement, Trinasolar's ESG performance dynamically influences its loan interest rate, enabling the company to lower financing costs by enhancing its sustainability efforts. The company noted that this performance-based interest rate mechanism translates ESG metrics into quantifiable economic value, demonstrating financial institutions' recognition of its ESG efforts.
