Description

Physical CharacteristicsMaterial: Polycrystalline Silicon Class:Grade ASize: 157mm*157mmThickness:180umFront:Five Silver busbars,anisotropically texturized surface with dark blue silicon nitride anti-reflection coating.Back: Full-surface aluminum BSF, Silver / Aluminum soldering pads.Electrical CharacteristicsEfficiency: 18.4%. Maximum Power(Pmax): 4.5WMaximum Power Point Voltage(Vmpp):0.540VMaximum Power Point Current(Impp):8.333AOpen circuit voltage(Voc):0.635VShort circuit current(Isc):8.797AConnection way: The blue side connect "-" (negative), white side connect "+"(positive). In order to ensure enough power, Suggest use photovoltaic tabbing wire to connect it. Note: 1. Because the output power of solar panels depends on solar irradiance and solar panel temperature and other factors Therefore, the measurement of solar panels need under standard conditions (STC). The standard conditions defined as: air quality AM1.5, light intensity 1000W/m2, temperature 25'. 2. Under this condition, the maximum output power by the solar panel is called the peak power. In many cases, the peak power of the module is usually measured by solar simulator.
