Product Feature:

High power output

Up to 21.3% efficiency for Mono cell and 20.0% efficiency for Poly cell, one of the highest performing crystalline cells on the market.

More bus bars
Four or five bus bars boosts current collection over the entire cell area, leading to higher fill factors and MORE POWER.

Excellent anti-PID performance
PID-resistant under the conditions: 85°C, 85% humidity, -1000V, 96 hours.

Lower power loss through encapsulation
Appropriate electrical performance parameters (high voltage and low voltage)  
Current evaluation and positive tolerance for the cell performance compensation guarantee a very low loss from cells to modules

Excellent solderability
Application of double-printing technology in production improves solderability.
