The process of connecting multiple PV cells together is called stringing. Cells are arranged together using automated stringing equipment (stringer with two robots and inspection units) employing pre-programmable software.

At this stage, the layup inspects the strings coming from tabber and stringer using artificial vision and accurately positions them over the glass +EVA substrate.

Visual inspection is carried out to eliminate any environmental, and electro-mechanical risk the completed modules may have. It is also done to evaluate design and production quality.

After a round of pre-lamination testing, the PV laminator bonds the multiple layers of material with thermoplastic films. Further, a vacuum process ensures the complete encapsulation of the photovoltaic materials. The interconnected solar PV cells are laminated with clear polymer-like material in highly automated laminators.
