Core Advantages

TOPCON Cells

TOPCon technology,higher power, overcomes LID and PID degradation.

Smart Soldering

Uniform smart soldering increases the power and efficiency of the module, and improves the power load capacity.

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.

Electrically Compatible

Lower Operating current,Good for distributed generation applications; Matches with various inverters and optimizers; Avoids wiring loss.

Smart Module Packaging and Logistics

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