Q CELLS QUALITY STANDARDS


Q CELLS QUALITY ASSURANCE

  • The strictest quality assurance for ultimate reliability
  • Three additional quality assurance programs instead of just one initial certification test.
  • Q.PRO G2: Best polycrystalline module in the 2013 and 2014 PHOTON Yield Measurement

QUALITY ASSURANCE TOOLS FOR PRODUCTION CONTROL

To meet the high demands of HQC, 3 tools are introduced in all manufacturing facilities

Permanent presence of HQC engineers on-site (supervised by German QM engineers)

Quality Sampling (supervised by German QM engineers)

  • Increased sampling at the module manufacturer site
  • 1 % visual inspection and wet leakage testing of total production per line daily
  • Daily 1 pcs for Grounding test / Reverse current test / High pot test
  • HQC on-site sampling

Quality Monitoring

  • Every month a random sample of 20 modules are tested by HQC Testing of OSC (optical sorting criteria)
  • Testing of performance (flash-test/ EL-inspection)
  • Determination of resistivity (wet leakage /high pot -test)
  • Quarterly 6 modules are tested for long-term stability (TC400/DH1500/PID)
  • More strict limit value for performance loss after all tests: max.5 % (IEC: 8 %)

PRODUCT QUALITY

HQC QUALITY PROGRAM

TEST HARDER

  • HQC qualification of products
  • HQC material tests
  • Q.Tested for modules
  • ISTA test for packaging

TEST CONTINUOUSLY

  • Q. Sampling
  • Q. Monitoring
  • Q.Tested quarterly reports

TEST MORE REALISTICALLY

  • Develop new, more realistic tests e.g. tilt snow load test
