Buy High Efficiency Taiwan bifacial Mono 3BB Solar Cells in Stock for Bifacial Solar Panels Making

High photoelectric conversion efficiency and reliability. A unique technology is used during the diffusion process to ensure uniformity. Its external uniformity is controlled with the use of an advanced PECVD forming technology, giving each solar cell its smooth surface coated dark blue silicon nitride antireflection coating. A high-quality metal paste is applied to each cell's back and lining to guarantee good electrical conductivity, reliable electrode absorption and adhesion. High-precise PSG etching and texturing makes each cell easier for post-production welding and laser cutting.

Q: What are the brand names of the solar cells Winsway distributes?
A: They include Taiwan NSP, Motech, Gintech, Tsec, E-ton,Sunrise and China Mainland brands such as Hanwha, Jinko, JA, Germany SolarWorld as well as USA brand Sunpower.

Q: For European market, how to avoid Anti-dumping tariff in European customs?
A: We imported solar cells from Taiwan. We provide Certificate of Taiwan Origin to cover Taiwan manufacturers that they are in "white list" according to COMMISSION IMPLEMENTING REGULATION (EU) 2016/185 of 11 February 2016. We are professional in such process to avoid high amount of anti-dumping tariff to benefit customers a lot.

Q: How about your solar cells monthly capacity?
A: More than 20MW.

Q: Is there any warranty for your solar cells?
A: Solar cells belong to fragile cargos, so normally there is no warranty. Our stand practice is when you receive our solar cells, please check it carefully at once. Any problems shall be timely feedback to us within 3 days with clear pictures and detailed report. We will check and confirm the problems and make up compensation for clients in the first time.

Q: How about the power scope of your solar modules?
A: Poly crystalline solar modules: 5w-310w

     Mono crystalline solar modules: 5w-330w

Q: Can you customize the solar panels for us?
A: Yes, but you should send us your requirement of the panels, such as the power, dimention, and Voltage you need.

Q: what’s your monthly capacity of solar modules?
A: Over 15MW

Q: How about the warranty of your solar modules?
A: - 25 years for OEM A grade.
     - 10 years for stock panels.

Q: How do I know what watts solar cells needed for making a 250w solar panel? 
A: Usually, it is 60pcs cells for a 250W solar panel. Then take this formula as a reference: module watts×1.02÷60. 250×1.02÷60=4.25W. 4.25W is single cell's power.
