With P-type cells, the base layer is doped with boron, which has one electron less than silicon. This creates an electron hole and the positive charge carriers predominate. In N-type cells, the base layer is doped with phosphorus. This has one electron more than silicon. This doping generates free electrons.The higher efficiency of N-type cells is caused by these free electrons. They are also responsible for the extremely low power losses and prevent phenomena such as PID and LID. Electrical SpecificationsModel of Solar PanelGSM570M10-144HCGSM575M10-144HCGSM580M10-144HCGSM585M10-144HCGSM590M10-144HCPeak Power Watts-Pmax(Wp)*570W575W580W585W590WMaximum Power Voltage-Vmpp(V)42.0742.2242.3742.5242.67Maximum Power Current-Impp(A)13.5513.6213.6913.7613.83Open Circuit Voltage-Voc(V)50.7450.8851.0251.1651.30Short Circuit Current-Isc(A)14.3114.3914.4714.5514.63Module Efficiency (%)22.0622.2522.4422.6422.84Power Output Tolerance-Pmax(W)0~+5Temperature Coefficient of Pmax-0.3%/ºCTemperature Coefficient of Voc-0.25%/ºCTemperature Coefficient of Isc0.046%/ºCSTCIrradiance 1000W/m2, Cell Temperature 25, Air Mass AM1.5 Packaging2279*1134*35mm / 29.4KG31 pieces / pallet, 620 pieces / 40HC ProductionMore than 3GW production capacity per year166mm, 182mm, 210mm solar panel production lineStrict quality control proceduresExport more than 160 countriesOEM service accept  QC Sysyem100% Solar Cells SortingColor and performance selectionTo ensure the production of high-quality cells, sort out unqualified products such as appearance defects, internal defects, and lack of process performance.Middle TestEVA and appearance inspection  Ensure PT / EVA size meets technical requirementsEnsure that the product is free of scratches, creases, debris, etc.Overall inspectionPV Module appearanceEnsure that the product has no color difference and no burrs.Make its reach Grade A standard.EL TestingSolar panel power inspection  Ensure that there are no cracks or defects inside the module.Ensure that the power meets customer standards. Project CasesCompanyWhy Choose GREENSUN Solar?1.We have professional photovoltaic partners in 20+ countries.2.Overseas warehouses in US and EU to provide more convenient and efficient services.3.Complete certifications and competitive prices.Q&AFAQ.1.What's your payment terms?TT,Letter of Credit,Paypal,Western Union etc. Could you send free sample?Your sample fee will be returned when your place next order.2.Can we print our own logo?Yes absolutely.3.What are the advantages of your company?We are factory ,now we control low margins for developing customers , price ,quality and service will never let customers down!!April 6th 2023 /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
