Components & Mechanical Data

Junction Box in proof-water with TUV Certificate
Bypass Diode Rated 15A
Solar Cable & Connector: 4 m� 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.

Under Standard Test Conditions(STC): Irradiance of 1000W/m2, Am1.5 and 25� C cell temperature
Operating Temperature: -40 ~ +85� C
Storage Temperature: -40 ~ +85�
