1) High module conversion efficiency, through superior
2) 0 to +5W positive tolerance for mainstream products
3) Certified to withstand high wind loads and snow loads
4) Anodized aluminum is mainly for improving corrosion resistance
5) Anti-reflective, Highly transparent, low iron tempered glass
6) Excellent performance under low light environment
Benefits of the solar panel
25-year performance warranty
10-year product warranty
1. All solar module produces without any aberration or bubble.
2. Back sheet is TPT&PET, and the thickness is 0.3mm.
3. The thickness of EVA is 0.4mm,better than other company use
0.3mm or 0.35mm.We use new EVA material, not the overdue, the
overdue EVA will influence the performance and lifespan of solar
4. New aluminum with 1.00mm thickness, high hardness, good impact
resistance. Some company will use bad recycle aluminum.
5. Tempered glass with 3.2mm has advantages of high strength,
impact resistance,good light transmittance.
6. The solar cells made in Taiwan, high efficiency, low
attenuation,the attenuation is less than 10% within 5 years and
less than 15% within 10 years.
7. The junction box has good waterproof, good anti-aging,PV wire.
The PV wire is good for anti-aging and anti-corrosion, it's better
than the normal wire.
8. Package by 7 layers thick carton, moisture proof and
anti-cracking. Two pieces in one carton, easy to delivery.

Poly Solar Panel
A polycrystalline solar module is made from a block of silicon that
has multiple crystals. These panels are square in shape, and may
have a surface that looks some what like a mosaic. This mix of
different crystals makes the polycrystalline module a good
performing type of cell. Polycrystalline solar panels historically
have been a popular choice.
Translucency of normal luminance is increased by 2%
Module efficiency is increased by 2%
Service life is as long as 25 years (30 years optional)
High Efficiency PV Cells
Color sorting ensure consistent apperance on each module
Silver or black frames are optional
Boost bearing capability and prolong service life
Serrated-clip design tensile strength
Seal-lip designglue injection
Conventional standalone edition and engineering custom edition
Quality diode ensures module running safety
IP67 protection level
Long service life
Anti-aging EVA, excellent weathering resistance TPT
