Key features:
• N-type i-TOPCon cells: Designed for efficient light conversion, including lower-light operating conditions.
• Dual-glass construction: Glass protects both faces of the cell assembly, with reduced exposure of a polymer backsheet.
• Temperature performance: The −0.29%/°C power coefficient helps limit output loss as cell temperature rises.
• Long-term power cover: The specified degradation allowance is 1% in the first year and 0.4% annually from years two to 30.
• System integration: Designed for use with mainstream solar components, subject to electrical and mounting compatibility.
