For cell and module manufacturing, MES can create a data thread across work orders, process revisions, equipment, material lots and product serial numbers, recording inputs, outputs, parameters and inspections at key steps. Across sites or lines, standardize identifiers, definitions and genealogy rules first, then configure workflows for local equipment and process differences.
Visual inspection, EL inspection, power testing and packing information can be recorded according to the factory’s quality system. Cell processes can also capture parameters and inspection results based on equipment capability. When a quality issue occurs, complete genealogy helps trace a finished product back to operations, equipment and material lots.
Inox Solar describes a solar business spanning cell and module manufacturing, as well as EPC and project operations. MES can coordinate with connected systems while keeping a clear role: manage shop-floor execution and product genealogy, and provide reliable data to planning, warehousing and quality processes through standard interfaces. Final scope should be phased around the actual factory and project agreement.
