Quality control plays a crucial role in the manufacturing of PV modules. The process is highly intricate and involves several components, such as silicon cells, glass, and wiring. While the production process involves collaboration with multiple suppliers and manufacturers, making quality control challenging.
The FQC refers to quality control of finished PV modules after they are cured. It mainly involves visual inspection, electroluminescence imaging, I-V measurement, ground resistance test and insulation test.
