Lineup of crystalline silicon PV module manufacturing equipment

NPC provides a wide range of equipment and engineering technologies for crystalline silicon module manufacturing. We have been continuing R&D since 1994, and have delivered optimized equipment to various customers worldwide. Utilizing our experience, we are making efforts to further develop technologies and adapt to new materials. In recent years, we have also provided equipment for manufacturing special purpose PV modules such as for satellites and shingling.

About Shingling

Shingling technology eliminates gaps between cells and the need for interconnecting ribbons so more solar cells are exposed to the sunlight and the resistive losses are reduced which make the module efficiency improve. Shingled modules are widely used in BIPV products such as residential roofs because of its beautiful appearance and higher efficiency even in a limited installation area.
