• Smart Soldering - Uniform smart soldering increases the power and efficiency of the module, and improves the power load capacity.

• Optimized Module Size - Large-format modules with M10 wafer size use dual-glass and frame packaging to ensure module strength.

• Smart Module Packaging and Logistics- Smart module packaging solutions are used to achieve high reliability, low-cost transportation and logistics.

• Optimized Electrical Parameters- The working current is about 13A, which is perfectly adapted to mainstream string inverters.

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

• 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.
