These monocrystalline solar modules are the right solution for an island system with their high power output and robust construction. Even when the sky is cloudy, the monocrystalline modules deliver a high energy yield.High efficiency: 50W of power for 4 hours of full sun exposure in one day, equivalent to 200Wh per day. This means that a 12V 20Ah device can be fully charged.Robust design: positive tolerance guarantee (0-3%); Withstanding wind (2400Pa) and snow loads (5400Pa) and IP65 junction box offers complete protection against environmental factors and low-pressure water jets.Tips for connectionStep 1: Please connect solar controller with battery firstStep 2: Then please connect the controller to the solar panelStep 3: To finish is the connection between the charge controller and the battery50W 12V solar panel monocrystallineRated power Pmax 50 wattsVoltage at rated power Vpmax 18 voltsOpen circuit voltage Voc 20 voltsShort circuit current Isc 0.37 ampsCurrent at nominal power Ipmax 0.33 ampsTemperature range -45°C to +85°CTolerance +/-5%Dimensions: 435*200*2.5mmLegal Notice1.
