Core Advantages

  • Half-Cell

    The power output of a bifacial half-cell module increases and energy yield is higher under high irradiance conditions because of low working current.

  • Mechanical Load

    Framed module, front/back side maximum static loading 5400/2400 Pa, makes it suitable for tracker mounts.

  • High Rating

    Glass and junction box, with high voltage grade, supports 1500V systems.

  • Bifacial Energy Yield

    Additional power generation from the backside of bifacial modules increases the overall energy yield, which has been verified by customers and third-party testing organizations.

  • Multi-busbar Design

    Our nine-busbar design improves current collection capability.

  • Low Degradation

    Anti-LID, anti-PID, 1st year degradation ≤2%, linear degradation ≤0.45%/year

  • Standard Module

    Our standard module is fully compatible with mainstream inverters and trackers, with no system matching issues.

  • Gallium-doped Technology

    Gallium-doped technology overcomes LID degradation and guarantees the long-term power generation of the module.

Sucessful Cases

LONGi’s high-efficiency modules have been deployed around the globe in just about every application possible across a wide range of climate conditions, including grasslands, farmlands, deserts, mountains, lakes and reservoirs, residential and commercial rooftops.
