Cells in: the high efficiency (more than 14.5%) of polycrystalline silicon solar energy piece of packaging, ensure that solar panels power generation power enough.


the added with ultraviolet agent, antioxidants and curing agent of the thickness of 0.78 mm high quality EVA film as a solar cell layer with glass, TPT sealants and the connection between the agent. Has the high light transmittance and anti-aging capability.


solar cells covering the back of fluorine plastic film-white, the reflection action of sunlight, so the component slightly increased efficiency, and because of its high infrared emissivity, still can reduce the working temperature of components, and also improve the efficiency of the components. Of course, the fluorine plastic packaging materials with first solar cell required ageing resistance, corrosion resistance, airtight, and other basic requirements



 the aluminum alloy frame has high intensity, mechanical impact resistance ability.
