The driving force of the new era of photovoltaic new energy change comes from the iteration of new process technology that can continuously increase efficiency and reduce cost, which also means the upgrading and replacement of a series of key photovoltaic manufacturing equipment.

As with the vast majority of manufacturing, core electrical automation and digital technologies are the key factors that currently constitute the advancement of equipment. Choosing a reliable, efficient, flexible, open, low-cost automation technology route with future digital transformation genes for photovoltaic manufacturing equipment will light the “light” on the road to the comprehensive rise of China’s photovoltaic manufacturing.

For decades, Beckhoff has been adhering to the innovative line of PC-based control technology, from industrial PCS, fieldbus components, drive technology, automation software to control cabinet automation solutions and machine vision solutions, Beckhoff has been working hard on this open road of new automation technologies. It is one of the world’s top suppliers in the field of PC automation control.

With industrial PC (including embedded PC) as the control core, EtherCAT high-speed Ethernet bus as the backbone architecture, servo drive as the motion actuator, TwinCAT software as the engineering platform and digital core, the photovoltaic manufacturing full chain solution has become a kind of technical model established by Beckhoff in the photovoltaic field.

From the mainstream single-crystal PERC cells to many process iteration routes of N-type high-efficiency batteries, the continuous reduction of photovoltaic manufacturing costs is still a top priority. With this solution from Befo, the production cost of solar silicon rods, solar cells and photovoltaic modules can be significantly reduced – whether it is silicon rod growth, surface processing and wafer cutting in silicon wafer manufacturing, fleecing, diffusion, etching, anti-reflective coating, screen printing and separation in cell manufacturing, or series welding, lamination, and other application scenarios in module manufacturing. All bring modular, scalable, open, reliable and future-proof competitive advantages.

Beckhoff’s PC-based open control technology is modular and scalable, making it particularly suitable for the automation of various processes involved in the growth, cutting, quality control and surface treatment of silicon rods, as well as the connection of individual production modules.
