Technical Advantages
High-Efficiency Integrated Automation
The Ooitech solar panel production line achieves an overall cycle time of 25 seconds per module across all process stations, enabling continuous high-volume output with minimal bottlenecks. The modular architecture allows individual stations to be serviced or upgraded without halting the entire line. The string layout robot delivers CCD vision-corrected positioning with accuracy of ±0.3 mm, while the framing and glass handling robots ensure ±1 mm placement precision throughout assembly.
Broad Module Compatibility
The production line is engineered to handle a wide range of module formats without major reconfiguration. It supports G1, M6, M10, and M12 cell sizes across standard framed, half-cell framed, and bifacial double-glass module types. Compatible technologies include PERC, TOPCon, IBC, ABC, HPBC, and shingled cell designs. Module dimensions from 1640 mm to 2500 mm in length and 992 mm to 1400 mm in width are fully supported, with format switching achievable in 10 minutes or less.
Intelligent Control and MES Integration
Every station on the production line includes a standard Ethernet data interface supporting MES connectivity. The system collects and reports operator information, equipment status, process parameters, maintenance records, and module traceability data linked to individual barcodes. MES data can be used to automatically adjust equipment parameters with authorized permission. All software is provided with annotated PLC programs, HMI programs, and electrical drawings, with lifetime free software upgrades.
Reliability and Safety Engineering
Equipment uptime across the line is guaranteed at 98% or above under full production conditions. Every machine incorporates multi-layer safety protections: short-circuit breakers on all motor loads, interlock guards on all service doors, safety light curtains at operator stations, pneumatic protective guards at glass infeed points, and tri-color alarm indicators with buzzers throughout. Emergency stop switches use 24 V low-voltage power supply with protective covers to prevent accidental activation.
Precision Conveyor System
The anodized aluminum conveyor framework maintains a maximum vibration amplitude below 1.5 g throughout the line. Green canvas synchronous belts are used upstream of the laminator for gentler module handling, while high-temperature-resistant green PU synchronous belts are used downstream to prevent belt marking on coated glass surfaces. Neighboring conveyor section height deviation is controlled within 2 mm, and transition points between stations use cushioned rubber rollers to eliminate surface scratching.
Advanced Process Stations
Dedicated specialized stations address the most demanding process steps. The bifacial edge sealing machine maintains tape edge placement error within 0.5 mm and prevents post-lamination EVA void defects. The junction box auto-soldering machine uses CCD-guided positioning with ±0.2 mm repeat accuracy and automatic tip cleaning cycles. The corner grinding machine controls grinding depth deviation within ±0.2 mm with vibration below 1.5 g to eliminate micro-crack risk. The insulation and hi-pot tester performs 6 kVDC testing in compliance with IEC 61730 with barcode-triggered automatic test sequencing.
Product Applications

Half-Cell Modules - Half-cell framed modules in all compatible size ranges are supported across the full line from glass loading through framing and testing. The line can simultaneously run standard and half-cell modules in mixed-flow mode.
Bifacial Double-Glass Modules - The line includes dedicated stations for bifacial glass splitting, second-glass lamination, and edge sealing specifically engineered for frameless and framed bifacial double-glass module construction.
Shingled Modules - Shingled cell string layouts are supported by the CCD-corrected robot layout station with programmable inter-cell spacing adjustable from 1 mm to 10 mm.
Production Capacity Range
Ooitech configures and delivers solar panel production lines for manufacturers across a broad range of annual production targets. Single-line configurations typically target 50 MW to 200 MW per year. Multi-line parallel configurations with shared testing and sorting infrastructure are available for 200 MW to 1 GW scale facilities. The modular design enables capacity expansion by adding process stations or parallel lines without disrupting existing production.
Target Customers
This production line solution is suitable for new solar module manufacturers establishing greenfield factories, existing manufacturers upgrading from manual or semi-automatic lines to full automation, contract manufacturers seeking to add new module technology compatibility, and solar project developers vertically integrating module manufacturing capacity. Ooitech provides complete factory planning support from equipment layout design through installation, commissioning, operator training, and ongoing after-sales service.
