Specification of  Solar Polycrystalline(270W-290W)

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.


Characteristics of Polycrystalline Silicon Solar Panel

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.

IV.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: ≥25 years; Less power decrease.

VII.Good performance of preventing from atrocious weather such as wind and hails.

VIII.Resisting moisture and etching effectively, not effected by geology.

IX.The certificate issued by international authority: UL, TUV, IEC, VDE, CE.


Standard Test Conditions of Polycrystalline Silicon Solar Panel

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 25°C, The info below is subject to manufacturing tolerances. Where appropriate minutes of measurement are available and are used for the dimensioning of the installation.
