Details Of Polycrystalline Solar Panel (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.


Main Features of Polycrystalline Solar Panel (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.

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.
