Build Witnessing

SolarBuyer build witnessing is designed to independently verify the materials and components used to assemble solar products for reliability testing. This is important to ensure the results of reliability testing can be reliably linked to a known set of materials and components.

The materials and components can later be referred to in supply contracts or checked during assembly of specific products for actual projects. This helps to ensure the reliability of shipped product matches the expectations set by testing.

In contrast, there is no material or component verification required for solar products built for IEC or UL certification type testing – even though certification is based on testing specific materials and components that are declared in writing by the manufacturer in advance of testing.

Build witnessing typically includes in-factory recording and verification of:

  • Certification conformance
  • Bill(s) of materials
  • Process parameters
  • Product metrics
  • QA-QC results
  • Flash test data
  • Electroluminescence images
  • Safety testing
  • Visual inspection

SolarBuyer will witness production, selects samples for laboratory testing, wraps the selected samples in tamper-proof security tape and provides a report detailing the results of the witness.
