Description of every parts:
1.Junction Box in proof-water with TUV Certificate

2.Solar Cable & Connector with TUV Certificate

4.Toughed Glass: The glass is super white cloth grain of toughened glass , the thickness of 3.2mm , the solar cell spectral response range of wavelengths (320-1100 nm), light transmittance over 91% , Ultraviolet light radiation , light transmittance is not falling .Toughened glass is made of components can withstand 25 mm in diameter of hockey hit at a speed of 23 m/s.

5.EVA: 0.5 mm thickness with high quality EVA film as sealant of solar cell and and the connection between the glass, TPT agent. With high light transmittance and anti-aging ability. Solar cell encapsulation of EVA film after curing performance requirements:
Light transmittance is greater than 91% ; Crosslinking degree is during from 70 to 90% ; Peel strength (N/cm), glass/film is more than 30 ; TPT/film is more than 15 ; Temperature resistance is from - 40° C to 85° C.

6.TPT BackSheet: the back of the solar panel, ageing resistance , corrosion resistance , resistance to ultraviolet radiation, airtight, etc. Basic requirements.

7.Frame: aluminum alloy frame with high intensit , mechanical shock resistance ability.Strong, lightweight aluminum frame design with reinforced sealing and load hold to prevent freezing and warping, and stand against high wind.
