**Quick answer:** The SC-20D is the dual-laser upgrade of the SC-20A, built for higher cutting throughput on the same cell formats. It runs two laser heads to cut 166 mm to 210 mm cells with a kerf near 0.05 mm, and serves module lines from 5 MW to 1 GW. Doubling the heads rather than raising the power of a single head is deliberate: cutting speed is limited by how fast the beam can travel without introducing thermal damage, so a second head raises throughput without pushing any single cut harder. The SC-20D takes up more floor length than the SC-20A and needs a matching layout allowance. If your line is limited by cell cutting rather than stringing, this is the station to look at first.

## Product Introduction

The **SC-20D Full Automatic Solar Cell [Laser Cutting](https://www.ooitech.com/SC-20P-Automatic-Solar-Cell-Laser-Cutting-Machine-High-Precision-BC-Cell-Processing-Equipment.html) Machine** is a higher-end upgraded model based on the proven **SC-20A platform**. It is **specially designed for shingled solar cell production**, and its core advantage is the **dual-laser-head design**, with **two laser units working simultaneously** to deliver higher throughput, more stable cutting performance, and better suitability for shingled cell processing in modern photovoltaic manufacturing lines.

The complete system integrates multiple sophisticated components including **A/B dual loading boxes**, automated loading robotic arms, precision positioning mechanisms, cutting workbench, X/Y cutting motion modules, dual fiber laser systems, optical path systems, unloading robotic arms, and finished product storage boxes. The equipment operates through a seamless automated workflow: the loading robotic arm picks solar cells from the loading box to the cutting workbench, where the positioning mechanism precisely aligns the cells. After positioning, the cells move to the cutting area where the X/Y cutting modules and dual laser heads work in coordination to complete cell division with higher efficiency. Finally, the cut cells are positioned and transferred to the corresponding storage boxes.

As a leading solution from **Ooitech** ([www.ooitech.com](http://www.ooitech.com)), specializing in 5MW to 1GW solar panel production line equipment, this machine embodies our commitment to delivering cutting-edge technology for the solar manufacturing industry.
