【Core Technology Advantages】

·High-Efficiency SHJ Solar Cells:The panels integrate Silicon Heterojunction (HJT) solar cells with a conversion efficiency of ≥ 25 % under standard test conditions (1 000 W/m²). HJT technology delivers excellent low-irradiance performance, typically generating more than 10 % additional energy compared with conventional cell technologies under overcast or high-altitude diffuse-light conditions.

·Flexible Silver-Wire Interconnection:Solar cells within the panel are interconnected via a proprietary flexible silver-wire structure that significantly enhances mechanical reliability and provides superior resistance to cell cracking and mechanical impact.

·No-weld contact: Forms an ohmic contact with the TCO layer on the cell surface; no welding required..

·40× current area: Provides 40× larger current-conduction area compared with conventional ribbon welding interconnection, enabling current to bypass damaged regions even in the event of micro-cracks — thereby minimizing power loss..
