Process
1
Glass Loading & EVA Sheet Placement
Tempered, high-transparency solar glass is automatically loaded, and covered with the first layer of EVA (encapsulant) film.
2
Cell Cutting, Tabbing & Stringing
Cells are laser-cut using NDC technology to reduce stress and avoid micro-cracks. The half-cells are then tabbed and stringed automatically for better performance.
3
Robotic layup
Robotic arms accurately place the cell strings onto the EVA/glass layer, ensuring proper alignment and spacing.
4
Auto bussing & Tapping
production line and highly information-integrated production mode, Astronergy enables the monitoring
5
Second EVA & Backsheet Placement
A second EVA layer is placed over the cell array, followed by an automated backsheet application to seal the rear side of the module.
6
Lamination
The entire module sandwich is sealed in a vacuum laminator. Controlled heat and pressure bond the layers into a single durable structure.
7
Edge Trimming & Framing
Post-lamination, excess EVA and backsheet are trimmed. Aluminum frames are installed and sealed using automatic framing systems.
8
Junction Box Installation
The junction box, with integrated bypass diodes, is attached, soldered, and bonded. It is cured to ensure long-term protection against moisture and electrical leakage.
9
Sun Simulation & EL Testing
Each panel undergoes EL testing to detect hidden cracks, flash testing to measure electrical performance (Voc, Isc, Pmax), and Hi-Pot & grounding tests to ensure insulation and safety as per IEC standards.
10
Automated Sorting & Packaging
Modules are sorted by power bin and visually inspected. Robotic packaging systems stack and secure the modules for shipping, ensuring safe and damage-free delivery.
