Solar Panel Manufacturing

High-Efficiency, Sustainable Photovoltaic Module Production

Strategic Goals

Efficiency & Quality

High-efficiency output (>21% for mono-PERC/TOPCon)
Zero-defect manufacturing with high throughput
Lowest cost-per-watt production

Sustainability & Scalability

Environmental compliance (low carbon, waste recycling)
Scalable production with robust QA/QC systems

Key Pillars

Precision Quality Control

Incoming material inspection (cells, glass, EVA, backsheets)
EL imaging for microcrack detection
IV testing for efficiency and performance
AI-driven defect detection systems

Lean Automated Production

Automated tabbing, stringing, lamination, framing
SMED for quick machine changeovers
OEE tracking for downtime and quality yield

Sustainability & Digitalization

Silicon wafer recycling and wastewater reuse
MES and IoT for traceability and predictive maintenance
ISO 14001 and RoHS/REACH compliance
