Product Details

 

---The average front conversion efficiency is above 19.10%.

---5BB design gets higher FF, lower Rs, and higher efficiency.

---Large size wafer, the effective illumination area is larger, and the power of the modules is significantly increased.

---CIR process decreases the LID/LeTID, makes sure the stable power output.

---Hot-spot inspection strictly, avoids loss of efficiency and reliability.

--AOI makes sure the better color uniformity of cells and modules.

Company Profile

Our Yongfeng is a professional manufacturer focusing on the solar panel and solar cell for 15 years.

 

Our company has developed into one of the main suppliers of solar panels and solar cells in China ,our factory have a

very strong production capacity that we can produce over 4,000 pcs for each model every day . 

We buy silicon wafer to make solar cells ,then make solar panels by ourselves ,so we have price advantages then other

factories and have formed a relatively complete middle-stream and down-stream solar power industrial chain.

Our sunjetpower plans to build most influential solar PV brand and bring best quality solar panels to our clients .
