For small and medium-sized PV manufacturers, mismatched production procedures and incomplete quality checks are primary causes of low finished product yield. The 5-100MW semi-automatic PV module production line is designed with flexible process compatibility, perfectly adapting to the iterative production of mainstream high-efficiency cells including TOPCon and HJT. It balances manual fine-tuning and mechanical precision to meet customized and standardized manufacturing demands.#PV production process#
Stable batch production relies on the coordinated operation of core mainstream equipment in welding and defect detection links. Standardized equipment configuration can effectively eliminate defective modules caused by manual operation errors and process deviations. As a professional PV manufacturing solution provider, Yoha Solar configures matched core production and testing equipment for semi-automatic lines to realize full-process quality control.#PV manufacturing solution#
Cell string welding is the core foundation of module assembly. The standard semi-automatic string welding machine adopted by the production line ensures uniform welding firmness between cells, avoiding common defects such as virtual welding and cold welding. It adapts to various mainstream cell sizes, providing stable structural support for subsequent packaging procedures.#PV string welding#
