Solar Cable & Connector: 4 m² with MC4 connector with TUV Certificate
1.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.
2. 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 90% ; Crosslinking degree is more than 65-85% ; Peel strength (N/cm), glass/film is more than 30 ; TPT/film is more than 15 ; Temperature resistance , high temperature 85° C , low temperature - 40° C .,
3. TPT Back-Sheet: the back of the solar panel, ageing resistance , corrosion resistance , resistance to ultraviolet radiation, airtight, etc. Basic requirements.
4. 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.
