LABORATORY TESTING

LABORATORY TEST

QPV has its own facilities to perform quality control tests on photovoltaic modules, for their qualification prior to their installation in a project or to verify their operation at a later stage. The tests included are:

EFFICIENCY PROTOCOLS

  • Single-facial module maximum power test
  • Maximum power testing of bifacial modules
  • Bifaciality measurement
  • Calibration of monofacial reference modules
  • Calibration of bifacial reference modules
  • LID test
  • PID test
  • Visual inspection
  • Thermographic inspection
  • Electroluminescence
  • Measurement of coefficients of variation with temperature
  • Electrical insulation test
  • Wet leakage current test

The above tests can be performed on both monofacial and bifacial modules and shall be performed in a manner consistent with international standards.
