Trina Solar Vertex Monocrystalline Silicon N-type Bifacial Solar Panels 715-740W 23.8% Efficiency Photovoltaic PV Module

1. Core Technology & Performance

Built on Trina’s 210mm cell platform and i-TOPCon Ultra technology, the TSM-NEG21C.20 series achieves power ratings from 715W to 740W with efficiencies ranging from 23.0% to 23.8%. Key performance highlights include:

Half-Cut & Non-Destructive Cutting: 132 half-cut cells reduce series resistance losses, mitigate hotspots, and minimize microcrack risks, enhancing long-term reliability and power stability.
Low Voltage Architecture: Optimized electrical design increases string power output, enabling fewer strings per inverter and significant BOS cost savings (typically 2–6% reduction in system-level costs).
Superior Energy Yield: A low temperature coefficient of -0.29%/°C minimizes power loss in high-temperature environments, while industry-leading low-light response and bifaciality (≥80%) deliver extra energy gains of 10–20% from albedo reflection in field conditions.
