How V-Trust Controls Solar Cell Quality
V-Trust delivers comprehensive solar cell inspection services, ensuring consistent product quality and regulatory compliance. Our quality control solutions cover all stages of smartphone production, including Sample Checks, Production Monitoring, During Production Inspection, Pre-Shipment Inspection, and Container Loading Supervision, reducing the risk of product failures and costly recalls.
Sample Check
Our engineers evaluate solar cell samples for conversion efficiency, material integrity, and safety compliance in certified labs. We verify cell grading, junction box waterproofing, and EL (electroluminescence) imaging results, ensuring performance aligns with technical specifications before mass production.
Production Monitoring
We conduct on-site oversight during critical stages like cell stringing, lamination, and framing. Our team tracks soldering quality, EVA film adhesion, and glass alignment to prevent delamination or micro-cracks before mass production advances.
During Production Inspection
Once at least 10% of the smartphone order is completed, we inspect randomized units for:
- Cell layup accuracy and tabbing integrity
- PID (Potential Induced Degradation) susceptibility
- Frame corner strength and grounding continuity
- Preliminary IV curve performance
This intercepts critical defects before full production completion.
Pre-Shipment Inspection
Before shipping, we perform full validation to confirm:
- Glass impact resistance and anti-reflective coating
- Junction box waterproofing and cable gauge
- Packaging durability
- Certification labels and documentation
Container Loading Supervision
We verify pallet stacking, moisture barrier installation, and battery component segregation. Container floor conditions and secure lashing are monitored to prevent glass breakage or corrosion during transit.
