What is Production Monitoring?

Production Monitoring is often referred to as a During Production Inspection (DUPRO) or In-line Inspection. Production Monitoring allows you to oversee the manufacturing of PV components from A to Z.

Our Production Monitoring services involve:

  • Primary material conformity verification
  • Compliance to Standard Operating Procedures (SOPs)
  • Monitoring of internal quality control system
  • Statistical tracking of defects and reworks
  • Production and testing equipment maintenance and calibration
  • Environmental conditions for each production area
  • Overall monitoring of production abnormalities

What are the advantages of Production Monitoring?

Inspecting your PV components during manufacturing stage offers the following advantages:

  • Improve and optimize the various production stages 
  • early identification and correction of deviations and quality problems

  • Gain full insight on your PV product quality already during manufacturing

  • Reduce your costs: prevent any recalls / damage of your reputation by replacement of defect PV components prior to shipment

  • Quality inspections on-site at solar factories

How is Production Monitoring performed?

Sinovoltaics typically performs Production Monitoring for solar module purchases of 3MW+, and it's usually combined with Pre-Shipment Inspections.

Production Monitoring starts from day 1 of production, and you can count on our Quality Engineers to be present throughout the entire production process.

Production Monitoring is executed according to the following procedure:

  • Client orders Production Monitoring with Sinovoltaics and the inspection is scheduled with the factory.
  • As soon as production starts, our team of PV Quality Engineers will arrive on-site at the factory to review the entire manufacturing process.
  • Any deviations and quality problems found will be directly solved on-site and communicated with our client.
  • A detailed inspection report will be issued within 2-3 working days.

What other PV-specialized quality inspection services do we offer?

Sinovoltaics' PV component inspections can be conducted at all stages of the manufacturing process. Production Monitoring is usually complemented by an Pre-Shipment Inspection, and Packing and Loading Supervision.  Sinovoltaics offers the following inspections:
