7> Communication with customers
A: Hello, Can you help me ? What’s the different from N type and P
B: Dear, We are ZOCEN SOLAR factory in China. Pleasure to help you.
During Diffusion process, B ion will be added for N type and P ion
will be added for latter; The former lifespan is much longer than
latter and also the efficiency is much higher.
A:At first cooperation, we want to test samples quality, do you
approve samples order?
How is your minimum order?
B:Yes, of course, we accept samples order begin. Minimum order is
A: How long time for 30,000pcs 156 x 156mm(6") Monocrystalline
A:Which shipping partner is available to UK?
B: DHL, UPS, TNT, FEDEX, EMS are okay. Which shiping cost is cheaper and speed is good, i will
suggestion to you. 3-4 days can arrive UK.
A: How long is your quality guarantee period
B: in usually,solar cell guarantee is 25 year.
A:Great, TKS. Do it.
8> Why choose ZOCEN SOLAR?
Jieyang Zocen Group Co., Ltd. is one of the leading manufacturer in
solar cells, solar panels and solar power system development,
production, sales and service. The company owns high level quality
management system and modern working environment.
Totally different from other crystalline solar cell in China, Zocen
solar focus on N type crystalline solar cell, which enjoy high
conversion efficiency and long lifespan. Due to its special and
difficult production process, we are the only 2 manufacurer of this
crystalline solar type in China and the largest solar cell
manufacturer in Guangdong province.
All of our customers had made remarkable progress and established
long-term business relationships with ZOCNE SOLAR in the pass. And
we firmly believe that there will be more promising in the
following couple of years based on our excellent R&D, stringent
QC and good service with Super high quality and new product.
