Poly solar panel 72 cells 320W-330W


IP68 Junction Box, Connector
IP68 Junction Box and Connector have a high degree of waterproof, effectively resist the harsh environment

15A current
The junction box carries a current of 15A, ensuring high current flow through the modules

Super strong frame
Glue-spilled tank has a double-layer waterproof, cross-section with hook-shaped aluminum frame, enhanced by 10% of the mechanical load strength

Current division
The module refines the current division, thus effectively reducing the loss of up to 2% due to mismatch and increasing the power output of the system

Salt spray, Ammonia and PID test
Excellent salt spray resistance, anti-ammonia and anti PID, TUV, SUD certification approved

Strong Mechanical load capacity
Passed the 2400pa wind load and 5400pa snow load test, ensuring that the module has a stable mechanical life

Color Classification
Modules are packaged according to color classification, to achieve consistent appearance after installation
