AmpleSun ASF sells well in Australia, Europe, South Africa, South and North America.

Amorphous silicon thin film solar panel, with TUV/ UL/ CE/ RoHS/ IEC/ CQC/ ISO/ SFEC/ CEC approval. have many advantages with high quality production process and raw materials: 

General advantages:

1. Good environment adaptability, less sensitive to installation angle, more suitable for vertical installation in BIPV.

2. Excellent performance.

3. 30% lighter than double-glass type.

4. Framed with aluminium makes ASF more solid.

5. Good looking, well match the buildings or as a constituent part.

6. Free from defects for 5 year with regular use, maintain more than 90% of Max. power for 10 years and 80% for 25 years.

Technical advantages:

1. Low temperature coefficient: 

Normally, the electricity performance of photovoltaic module is measured by STC standard. However, the temperature of solar module, operating in the sun, can be much higher than atmosphere temperature.

With the temperature increase, module power will decrease accordingly. Temperature coefficient for thin film silicon solar cell is 0.2%/0c, and that of crystalline solar cell is -0.5%/0c. That means, when the module is worked on 500c condition, compare to the efficiency reached on 250c test standard , thin film silicon solar module will loose around 5%, and the loss for crystalline will be around 12.5%. 

In conclusion, even the STC efficiency of thin film silicon solar cell is low, the efficiency in actual operation condition is not far away to that of crystalline solar cell.

2. Good weak light performance: 

The performance of thin film silicon solar cell is better than that of crystalline solar cell in the weak light condition. 

Solar power system with crystalline solar module will not generate power in the late afternoon. However, solar power system with thin film silicon solar cell still generates power.

Furthermore, thin film silicon has gentle current-voltage curve. This characteristic makes it easier to pick-up the most electricity power.
