ENGINEERING CONSIDERATIONS
What to define before the trial.
Coating durability
Black busbar approval can include heat exposure, cross-cut adhesion and pencil-hardness checks.
Segment positioning
Round and flat section lengths must be coordinated with cell format, string layout and winding orientation.
QUALIFICATION PATH
From requirement to approved supply.
Use the customer's real cell, flux and production equipment to turn representative material data into an approved supply window.
- 01Select reflective, black or segmented platform
- 02Define geometry and appearance criteria

TECHNICAL FAQ
Questions buyers ask before sampling.
Can reflective groove geometry be customized?
Representative geometry is listed above. Customer-specific optical and dimensional requirements can be reviewed during specification definition.
How is black coating checked?
Representative checks include 380°C for 5 seconds, cross-cut grade 1 and pencil hardness of at least H, subject to the final agreement.
Which cell formats can segmented ribbon support?
The platform is intended for application-specific designs including common 182 mm and 210 mm cell formats.
