MULTICRYSTALLINE SILICON SOLAR MODULE
The multicrystalline silicon solar modules are composed of solar cells with the average conversion efficiency above 15%, EVA sheet, solar glass and Tedlar (TPT) back sheet compounded from fluoric-plastic and dacron. The module adopts reliable welding technology and high-vacuum heating lamination process and is equipped with anticorrosion-treated aluminum alloy frame and watertight terminal box, According with IEC61215 and the II grade standard electrically. As a result, it takes on a rational structure, has an ultraviolet aging resistance.
Design the characteristics:
Even under the condition that the light is dim,
the multicrystalline silicon solar cell of above
15% of the efficiency can produce the electricity
greatly in the greatest power output;
Power output match with the most ideal solar module
With defended and reflected membrane and high transparent
glass, the module can increase the energy greatly;
Firm frame reliably:
Only for 46mm thick extremely thin positive pole
anticorrosion-treated aluminum frame;
Safety glass and protect back sheet can avoid damage and
water;
Pour into the terminal box that the silicon froze the glue;
Utilize EVA and TPT can prevent water entering effectively.
Seamless system conformity:
On the frame opens has 4 - 6 holes, is easy to install in all systems structure;
Provides the standard MC attachment and the 1m long electric cable;
Has 3 diodes in the joint box, greatly reduced the system power loss which camouflaged from the module.
