Catch transport damage before installation - responsibility assigned, not argued.

Damage between the factory and your site is invisible until energisation. Sinovoltaics inspects your modules on delivery and compares them - per serial number - against their factory EL images, so transport and handling damage is documented before a single module reaches the racks.
[Schedule an on-arrival inspection]

What on-arrival inspection covers
Post-shipment (on-arrival) inspection verifies the condition of PV modules at delivery - combining visual checks and electroluminescence imaging at the warehouse, port or project site - to document transport and handling damage before installation, while responsibility can still be established.

Included:

  • EL + visual inspection on delivery - at EU warehouses, ports or project sites
  • Sampling per contract AQL - or 100% sorting of suspect batches when packaging, pallets or early samples show damage
  • SELMA comparison against the factory EL images of the same serial numbers
  • Damage documentation with evidence - transport vs handling vs manufacturing, photo- and EL-documented per module
  • Fast batch release - accept/reject decisions at delivery speed, protecting your installation schedule


Deliverables: batch release report, per-module defect list with serial numbers, claim-ready evidence package for carrier, EPC or manufacturer claims.

The window that closes at installation
Every stakeholder’s liability changes the moment a module is mounted:

  • Before installation, damage is provably the manufacturer’s, carrier’s or handler’s problem - if you have evidence.
  • After installation, every party points at the installer, and the installer points back.

Modules cross oceans, change hands at ports, warehouses and laydown areas, and are moved by crews under schedule pressure. Microcracks from any of these steps are invisible to the eye and dormant in year-one performance - then grow under thermal cycling into the yield losses and hotspots of years three to ten.

An on-arrival inspection is the last moment this damage is cheap to fix: reject, replace or claim - before racking.

Factory twin comparison: the responsibility machine

Where Sinovoltaics inspected your modules at the factory, every on-arrival EL image is matched by SELMA against the factory image of the same serial number:

  • Defect present at factory → manufacturing issue → module warranty claim
  • Defect new on arrival → transport/handling → carrier or logistics claim
  • Clean on arrival → your baseline for construction QA and annual health checks


This is the difference between “the modules are damaged” and “these 214 modules were damaged after leaving the factory and before delivery - here is the evidence per serial number.”

When you need this

  • A module delivery is scheduled and your contract has an acceptance window
  • Packaging, pallets or containers show visible damage on arrival
  • You are storing modules at a warehouse before construction
  • The EPC and supplier disagree about who damaged what
  • Your lender or insurer requires incoming-goods verification


Engagement model
Per-project, volume-priced. Standard add-on to every Sinovoltaics factory QA contract - the final step of the supervised supply chain and the first step of your field quality file.

The claim window closes when racking starts. Inspect first. → Schedule an on-arrival inspection

Frequently asked questions

  • How fast can a batch be released? Inspection is scheduled to your delivery calendar; accept/reject decisions per batch are typically same-day or next-day, so trucks and installation crews are not held up.
  • What share of shipments show transport damage? Industry field data consistently shows transport and handling among the most common sources of cell cracking. The rate varies with packaging, route and handling - which is exactly why per-delivery evidence matters more than averages.




All three. Unloading monitoring and in-warehouse inspection with sorting are often the most efficient approach - suspect batches are quarantined without touching site logistics.

  • Can this run without factory EL images? Yes. On-arrival EL then serves as the earliest baseline for all future comparisons - still decisively better than installing unverified modules.
