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. The solar modules benefit customers and communities with advantages such as greater efficiency and performance, lower light degradation and better reliability.
- 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.
Multi-busbar Design
Our nine-busbar design improves current collection capability.
Mechanical Load
Framed module, front/back side maximum static loading 5400/2400 Pa, makes it suitable for tracker mounts.
Low Degradation
Anti-LID, anti-PID, 1st year degradation ≤2%, linear degradation ≤0.45%/year
High Rating
Glass and junction box, with high voltage grade, supports 1500V systems.
Standard Module
Our standard module is fully compatible with mainstream inverters and trackers, with no system matching issues.
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.
Gallium-doped Technology
Gallium-doped technology overcomes LID degradation and guarantees the long-term power generation of the module.
