Jiangsu CASI Solar Co., Ltd. Quality Control

"Being a 11 years worker in solar battery industry, I was confused every time

when I faced to a huge price competition that whether should we use

low quality raw materials or even add glass or stones to reach high weight?

We stick to high level materials at last because of our neighbor battery factory

shut up because of fire disaster of batteries which installed only 1 year.

During the past 11 years, we OEM for many famous brands home and abroad

and won an excellent reputation because of not only much cheaper price than same quality

in the market, but also less after-sales. We make sure stable quality from 3 aspects.

Let's see one by one."
