In order to realize high utilization rate and efficiency, British Solar divide the PV module production process into different technological modules all of which are relatively independent and highly associated. By studying all these modules precise, the company finally improves the overall reliability and design quality of the products and make production line configuration and model change easy. The production workshop provided with over 40 production line optimization patents can avoid artificial human errors effectively and ensure the operation precision of all production links from incoming inspection to packaging; it also saves the production data for problem follow-up.
