Solar panels are made of monocrystalline or polycrystalline silicon solar cells, series connection or parallel connection, then hot-pressed and sealed by tempering glass and EVA,TPT, equipped with aluminum alloy frame.

1. Tempering glass
Low iron tempered glass(also named white glass), common thickness 3.2 mm or 4 mm, the transmittance is up to 90% , This glass also resists UV light radiation, and its transmittance is not falling.

2. EVA 
EVA is a kind of hot melt adhesive, the thickness between 0.4 mm - 0.6 mm, smooth surface, uniform thickness,

3. soler cell
Solar cell is the smallest unit of the photoelectric conversion, its working voltage is about 0.5 V,

4. back veneer
Back veneer is that the protective material of the back of solar panels, including TPT, BBF, DNP, etc.

5. junction box
Junction box is generally is made of ABS, adding anti-aging agent and resist UV radiation agent.

6. aluminum alloy frame
Frame adopts hard aluminum alloy, thickness of surface oxidation layer is more than 10 micron, it can ensure 25 years'
