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.
