Solar energy is green environmental source which is unlimited, clean and pollution-free and reproducible. Photovoltaic 

energy, which generates power from solar energy, is considered as one of the most important new energy in 21st century. It 

has incomparable cleanliness, high security, relative universality and adequacy of energy, long lifespan, maintenance-free 

and other advantages which are not owned by conventional energy.
Solar module
1. Lifespan: 20-25 years
2. Solar module adopts high-transmittance and low-iron tempered glass. Back side adopts white TPT or PET substrate.
3. Imported mono-crystalline solar cells are adopted and the average conversion rate is over 16%.
4. Component’s border: it is made of anodized high-quality aluminum alloy. The thickness of surface alumina film is 25um. 
5. Tempered glass: component’s surface glass is low-iron tempered glass(iron content is less than 0.02%). Thickness: 3.2mm; 

transmittance>92%
6. Sealing material: it is sealed by imported anti-aging and good weather resistant high-quality material. It will not age or 

crack between -50℃ and 50℃
7. Dust-proof junction box: high-quality material is used to make junction box’s shell and inner insulating material. 

Galvanized copper electrode material is used to make terminal. It has good leakproofness, waterproofness, salt resistance and 

moisture resistance.
