Quality Control System

Can be summarized as follows:

  • SUNFARMING quality controllers regularly check the production and do final inspection of the modules in the partner factories
  • In co-operation with TÜV Rheinland and the Photovoltaik Institut Berlin, we check samples of each container and undertake additional tests
  • By an extensive and detailed online monitoring, we supervise the module quality long-term
  • Insured transport with a German forwarder ex-works to final destination
  • We only purchase modules with plus tolerance
  • We randomly take out test modules of each container and undertake STC-(performance) tests in an external test institute like the TÜV
  • In each partner factory we have a reference module calibrated by TÜV for the calibration of the manufacturers flash machine

  • Re-insurance of the performance warranty
  • Certificates IEC/EN 61215, IEC/EN 61730-1,2, MCS, UL, CE
