PV MODULES’ QUALITY CONTROL

OBJECTIVE

Analysis of the PV modules’ performance before and after their reception in the field.
We verify if there is any manufacturing, transport or installation defect, and guarantee their production capacity.

PROCEDURE

  • Visual inspection according to international standards and the manufacturer’s requirements.
  • Electroluminescence tests and revision of any possible defects.
  • I-V tests under real sun conditions and calculation of the STC parameters.
  • Electric isolation and withstanding tests.
  • Light Induced Degradation (LID) test.
  • Potential Induced Degradation (PID) test.
