Solar BOS Inspection Checklist
A buyer-side inspection checklist for solar BOS orders, covering product matching, dimensions, electrical ratings, labeling, packing, photo evidence and loading readiness.
Quick Answer
A strong BOS inspection checks product identity, key dimensions, electrical ratings, labeling, carton/pallet condition, quantity, wiring layout for assembled boxes and shipment photos before cargo release.
Inspection Scope Matrix
Different BOS product groups need different QC evidence.
| Product Group | Inspection Focus | Photo Evidence | Buyer Check |

Solar BOS Inspection Checklist FAQ
When should inspection requirements be sent?
Inspection requirements should be included in the RFQ or PO so the supplier prepares labels, packing and photo evidence before production ends.
Is photo inspection enough for BOS orders?
For many repeat orders it can be enough, but first orders, high-value items and assembled boxes may need sample checks or third-party inspection.
What is most important for mixed BOS shipments?
Clear SKU separation, carton labels, pallet labels, packing list consistency and loading photos are critical for mixed shipments.
