Solar Polycrystalline Panels (25W-35W)
Introduction of Solar Polycrystalline Panels (25W-35W)
Solar polycrystalline panels 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 Solar Polycrystalline Panels (25W-35W)
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. .
