How to control quality?
 - Vertically integrated production line from silicon ingot- silicon wafers- solar cell- solar modules assembly  with highly automatic production line;
 - 90% equipment is imported from Europe, USA, Japan;
 - Production line are certified by America company DNV KEMA;
 - Strategic cooperation with TUV, randomly checking for production line, making sure the production line is  under the best situation;
 - More than 4 quality control points in each production process;
 - All the staff went through strict training and testing before start work;
 - All the equipment do calibration every 24 hours;
 - R &D center focus on high efficiency solar cells and stable, higher output solar panels;
