On March 4, the Administrative Examination and Approval Bureau of the Yangzhou Economic and Technological Development Zone officially approved the TOPCon Generation-2 and BC (Back Contact) product upgrade and transformation project for Yangzhou Canadian Solar Battery Co., Ltd.
According to the announcement, the developer of this upgrade and transformation project is Yangzhou Canadian Solar Battery Co., Ltd. The construction site is located in the Yangzhou Economic and Technological Development Zone in Yangzhou City, Jiangsu Province, specifically south of Wuzhou Road, east of the Mapo River, west of South Canal Road, and north of the Shengli River.
