Description of every parts:
1. Junction Box in proof-water with TUV Certificate
2. Bypass Diode Rated 45V&15A
3. Solar Cable & Connector: 4m² MC 4connector 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.

HOW KELAN SOLAR DO QUANLITY CONTROL?
-Vertically integrated production line from silicon ingot- silicon
wafers- solar cell- solar modules assembly with highly automatic
-90% equipment is imported from Europe, USA, Japan;
-Production line are certified by America company DNV KEMA;
-Strategic cooperation with TUV, randomly checking for production
line, making sure the production line is under the best situation;
-More than 4 quality control points in each production process;
-All the staff went through strict training and testing before
-All the equipment do calibration every 24 hours;
-R &D center focus on high efficiency solar cells and
stable,higher output solar panels;
-Strictly raw material checking for raw silicon, glass, backsheet,
EVA, Junction Box, etc.
