Frequently Asked Questions (FAQ)
What is the annual production capacity of this solar line?
The production line is configurable for capacities ranging from 100MW to 600MW per year.
Which types of solar cells can this equipment process?
It is compatible with all modern cell types including Perc, Topcon, HJT, IBC, HBC, and Sunpower, with sizes ranging from 156mm to 230mm.
How does the EL Tester help in quality control?
The EL Tester identifies invisible defects such as micro-cracks, broken finger wires, and cold solder joints that cannot be seen by the naked eye.
Does the line support double-glass module production?
Yes, the system is fully compatible with regular 60/72 cell modules as well as double-glass and half-cell modules.
Is the NDC (Non-Destructive Cutting) machine essential?
The NDC machine is highly recommended for high-efficiency cells as it uses thermal laser separation to cut cells without damaging the edges, preserving cell integrity.
What kind of after-sales support is provided for international clients?
We offer comprehensive customer site installation and remote technical support to ensure smooth operation of the production line.
