Quali lity ty Cont ntro rol
EMS- Electronic Management System
- 16 in-line quality control points in module workshop
- Precise data-recording & supervision for all the manufacturing QC points
Product Traceability Control
- Tracking card with unique barcodes tracing from module back to ingot
- SAP process traceability system with 26-year data storage.
- 40 in quality checkpoints in the entire process
Employ Electroluminescence Test (EL) to inspect for potentially defective cells.

Micr cro-crac cracking ng
Portable EL Microcracking can lead to hotspot, power degradation and snail trails Generally the snail-trails will happen after more than half a year on-site, through simulation we can predict the probability and severity . Microcrack & Snail-trails Simulation

Hot Spot Elimination
Cell Shading condition Maxim temperature from test Delta Mc-Si Full cell 115.4 / ½ half cell 96.0 19.4 Mono PERC Full cell 122.4 / ½ half cell 98.0 24.4
- Current, thus
Power of half-cell is halved
- Lower Power
dissipated on shaded cell
- Around 20°C
lower temp. In hot spot test
- Less risk for
