??Details OfÿPolycrystalline Solar Panelÿ(25W?310W)CNBM Solar photovoltaic (PV)module is designed for large electrical power requirements.It is the optimal choice for both on-grid and off-grid power systems.CNBM Solar panel offers high performance of power per square foot of solar array.Poly- or multicrystalline silicon(poly-Si or mc-Si): made from cast square ingots ? large blocks of molten silicon carefully cooled and solidified.Poly-Si cells are less expensive to produce than single crystal silicon cells, but are less efficient.US DOE data shows that there were a higher number of multicrystalline sales than monocrystalline silicon sales.ÿMain Features of Polycrystalline Solar Panelÿ(25W?310W)I Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.II Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.III EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.IVÿ AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.V Junction box: Multi function junction box with water proof.VI Long lifetime: ò25 years; Less power decrease.VII Good performance of preventing from atrocious weather such as wind and hails.ÿTemperature Coefficient of Polycrystalline Solar Panelÿ(25W?310W)NOCT47?ñ2?Temperature Coefficients of Isc (%/?)0.064Temperature Coefficients of Voc (%/?)-0.33Temperature Coefficients of Pmp (%/?)-0.45ÿOperating Temperature?40 øC to +85øCStorage Temperature?40 øC to +85øCMax System Voltage700VÿProducts Guarantee2 yrs free from defects in materials and workmanshipPerformance GuaranteeNo less than 90% within 10yrs and no less than 80% within 20yrsCertificatesISO, TUV, CEÿStandard Test Conditions of Polycrystalline Solar Panelÿ(25W?310W) The opto-electrical specifications shown below are stabilized values being measured at Standard Test Conditions of multicrystalline silicon Solar Panel, Irradiance: 1000W/m2, Spectrum: AM1.5 at 25øC, The info below is subject to manufacturing tolerances.
