330W Poly Solar Module


Product origin :Xingtai, China

Delivery time :With 10 days after getting deposit

Supply capacity :4x40'HQ per day

SB 5BB design module reduce cell series resistance and stress between cell interconnectors improves module and module conversion efficiency;
High power output of more than 330 W and module efficiency up to 17.5% which has been verified by TUV Rheinland;
Anti-reflective and anti-soiling surface reduce power loss from dirt and dust;
Outstanding performance in low-light irradiance environments. Module contains element but does not supply power to external load&has bypass diode for array shading protection;
Positive power tolerance:0+3%
100% EL double-inspection ensures modules are defects free;
Modules binned by current to improve system performance;
Potential induced Degradation(PID) Resistant
Excellent mechanical load resistance: Certified to withstand high wind loads(2400Pa)and snow load(5400Pa)
