PV plant and modules inspections China

PV factory and PV module inspections in China by local teams

Are you a PV power plant owner or an EPC and planning to purchase solar panels from China? Then it can be important to realize that the value of the PV modules is almost half of the value of the solar power plant investments. The solar panels will have to endure hard and continuously changing outdoor conditions for a period of over 25 years and bad components are relatively hard to replace. Therefore PV Factory inspection can be of great importance to your future power plant. The advantages can be tremendous: Increase Pmax from day 1, lower degradation rate, less and later incidental failures, longer effective lifespan.

Factory Inspection of PV modules in China

Increase Pmax from day 1, lower degradation rates, les and later incidental failures, longer effective lifespan.

The prevention or timely detection of poor or underperforming PV modules has some very important benefits for the PV modules in your upcoming power plant:

  1. Increase Pmax from day 1
  2. Lower degradation rate
  3. Less and later incidental failures
  4. Longer effective lifespan

The payback period of a factory inspection for PV modules from China is usually less than 1 year. A complete factory inspection consists of a number of components, but it is also possible to make a selection from these:

  1. Audit PV production plant
  2. Inline Production supervision
  3. EL review
  4. Third Party Lab testing
  5. Pre-shipment inspection PV modules
  6. Truck Loading inspection
  7. Possible to do a Site Acceptance Test (SAT) in the ports of Rotterdam and Valencia before customs

Audit PV production plant in China

Determine production readiness and weakest links.

During an audit of the PV plant, the entire production process is being analyzed in order to determine production readiness and weakest links. A QAP/QCP will be installed with control points and tests. QMS will imply actual ISO implementation. The equipment will be calibrated and all key materials will be sample tested.

Inline PV production supervision in China

Red flagged risks, EL image review and third party lab testing.

During the inline PV production supervision stage, the BOM will be verified. Risks will be identified from serial defects (red flagged) and EL images will be reviewed during production. The PV modules will be tested in house as well as by a third party lab.

Pre shipment inspection PV modules in China

Eliminate microcracks in the solar panel, pv soldering defects and other problems

The PV modules to be shipped are randomly tested according to ISO 2859-1 on the basis of visual inspection, safety inspection (high voltage no short circuit), EL testing and Flash testing. Thanks to these tests, several problems can be prevented, from so-called microcracks in the solar panel to pv soldering defects and other problems.

Optional: a Site Acceptance Test (SAT) in the ports of Rotterdam and Valencia before customs

A Site Acceptance Test in the harbor prior to passing the Dutch customs can save a lot of time and issues as there has not been a change of ownership yet.

The Eternal Sun group together with its companies OdinSpire, Spire Ibera is able to provide a Site Acceptance Test (SAT) in the ports of Valencia and Rotterdam. In the harbor of Rotterdam alone about 80% of all PV modules destined for the European market pass through. A Site Acceptance Test in the harbor prior to passing the Dutch customs can save a lot of time and issues as there has not been a change of ownership yet.
