1. Better appearance 
Without the visual impact of the  welding strips on the front-side, the pure beauty of the solar cells is perfectly presented. 

2. High power generation efficiency 
There is no metal  welding strips on the front-side of the module. The power generation area of the front-side increases by 2.5%. 

3. No light pollution 
The light reflectivity of the module is only 1.7% due to no  welding strip technology on the front-side. It reduces light pollution to the environment and neighbors. 

4. No hot spot effect when be blocked 
Using unique all back contact technology, the the positive and negative metal electrodes flow normally on the back-side when be blocked, reducing the risk of hot spots. 

5. Long warranty of 25 years 
The encapsulating materials use TPE backsheet, which is covered with PVF (Tedlar) film and use improved EPE film, ensuring service life of 25 years. 

6. Better performance in low light scenes 
No shield of metal electrodes on the front-side enables a spectral absorption range of 300nm-1200nm, which extends the working time. The maximum power generation gain is 2.01%.
