These inspections can be performed at various stages, including: Apart from our quality control inspections for solar PV, we provide a variety of vendor assessment services.
One effective method is to conduct a during-production inspection. This quality check thoroughly inspects each panel's materials, manufacturing process, and performance characteristics to ensure they meet the required standards. Ensuring the quality of solar panels during production inspection is important for multiple reasons:
Needless to say, it is imperative that solar panels are not only manufactured using high-quality components but that they also undergo stringent quality control inspections – whether through an in-house QC inspection or a third-party inspection – before shipment.
In a single inspection step, CELL-Q checks every solar cell's print quality and anti-reflection coating. Any print and color defects on all cell technologies are reliably detected.
