450W Mono Solar Panel with Solar Module Half Cell Sliver Topcon Allblack

Product Description GKA72M-166 450Watt  Mono Crystalline ModuleSolar panel cell: 6BB 166mm*166mmProduct ParametersKEY FEATURES6 Busbar Solar Cell: 6 busbar solar cell design module improves efficiency and offers a better aesthetic appearance, making it perfect for rooftop installation. High Efficiency:Higher module conversion efficiency(up to 24.67%) benefit from Passivated Emmiter Rear Contact (PERC) technologyPID Resistance:GAMKO modules pass PID test, limited power degradation by PID test is guaranteed for mass production. Low-light Performance:Advanced glass and surface texturing allow for excellent performance in low-light environments. Severe Weather Resilience:Certified to withstand: wind load (2400 Pascal) and snow load (5400 Pascal).Durability against extreme environmental conditions:High salt mist and ammonia resistance certifified by TUV NORD.Temperature efficient:Improved temperature coefficient decreases power loss during high temperatures.Our AdvantagesGAMKOGAMKO SOLAR MODULE BOMCELLS:JINKO,GCL,TONGWEI,LONGI TEMPERED GLASS: AVIC SANXIN EVA: FIRST EVA BACKSHEETS: JOLYWOOD JUNCTION BOX: QC,RENHE SILICON GEL:TONSAN FRAME: CHINA ALUMINUM AMKO SOLAR MODULE BOMGAMKO QUALITY CONTROLGAMKO QUALITY CONTROLGAMKO QU    GAMKO QUALITY CONTROLCONTROLGAMKO QUALITY CON*2 EL testing avoid cells cracking of each solar module. *2 Power flflash testing avoid false welding and insufficient power of each module.* Packing tightly with angle protection avoid transportation broken. *Zurich Quality Insurance cover all Gamko solar module 30 years.Nominal Power (Pmax)                                                             420W                        430W                        440W                        450W                        460W      Open Circuit Voltage ( VOC )50.6V50.8V51.0V51.2V51.4V      Short Circuit Current (ISC )10.58A10.70A10.82A10.94A11.06A      Voltage at Nominal Power (Vmp)42.0V42.2V42.4V42.6V42.8V      Current at Nominal Power (Imp )10.00A10.19A10.37A10.56A10.75A      Module Efficiency (%)19.29%19.75%20.21%20.66%21.12%      Operating Temperature-40°C to +85°C      Maximum System Voltage1000VDC /1500VDC      Fire Resistance RatingType 1(in accordance with 1703)/Class C(IEC61730)      Maximum Series Fuse Rating20A  *STC: lrradiance 1000W/m2 ,, Cell temperature 25°C, AM1.5        ELECTRICAL CHARACTERISTICS AT NOCT      Nominal Power (Pmax)311W318W326W329W333W      Open Circuit Voltage (VOC)46.6V47.1V47.7V47.7V47.8V      Short Circuit Current (ISC )8.57A8.67A8.77A8.86A8.95A      Voltage at Nominal Power (Vmp)37.8V38.3V38.7V38.8V38.8V      Current at Nominal Power (Imp)8.20A8.30A8.39A8.48A8.56A  *NOCT: Irradiance 800W/m2, Ambient temperature 20°C, Wind Speed 1 m/s        MECHANICAL CHARACTERISTICS      Cell type                                                       Mono 166x166mm Nominal Operating Cell Temperature (NOCT)     45°C±2°C      Number of cells      144(6x24)    Temperature Coefficients of Pmax-0.39%/ºC      Module dimensions2108x1048x35mm    Temperature Coefficients of VOC-0.30%/ºC      Weight25kg    Temperature Coefficients of ISC0.0.06%/      Front cover3.2mm,Anti-Reflection Coating,Tempered Glass       FrameAnodized Aluminium Alloy      PACKAGING      Junction boxIP67 Rated    Standard packaging31pcs/pallet      CableTV 1×4.0mm2,Length:300mm or Customized  Length    Module quantity per 20'container285pcs      ConnectorPV Connector (compatible)    Module quantity per 40'container570pcs(GP)/682pcs(HQ)COMPANY PROFILE Gamko energy, Worldwide Energy and Manufacturer, is a professional solar module manufacturer with a 10-year experience in  production and quality control since 2008. Gamko is also a provider of technical services for solar power plant(on-grid and off-grid), including technical design, installation and maintenance, for customers all over the world.In August 2013, Gamko adjusted its strategy and started to cooperate with the top-level factories in Taiwan, South Korea and USA to produce GAmko modules. With the best and most advanced production equipment in different countries, In 2018, we have a production capacity of 700MW.FAQ:Q:We like to buy your panels, cause the price is good, but the price is not most important, I don't like to buy the trash, how do I know your solar panel have a good quality, everybody say they are A grade panels, how I can trust you?A:Firstly, we make new panels not stock panel, we will providing the flash test report,Series number, Power rates , voltage, current all mentioned on the flash test report for individual solar panel, The stock panel have no any database. You don't know if they are defective or broken panels. But its not enough. Please ask Gamko provide the flash test photo and EL photo for each panel.Q:I am also worry about my payment safe, How can you guarantee me 100% payment security?A:if you do worry about the payment safety so either I, lets do "Alibaba Trade Assurance Payment" for both safetyQ:How do you comply with your warranty terms if the sola
