CALIBRATION OF PV REFERENCE MODULES

OBJECTIVE

Calibration of PV modules as irradiance and temperature sensors to be used as reference in the field.
We guarantee the traceability to international primary references and the lowest result uncertainty.

PROCEDURE

  • Electroluminescence tests for physical defects detection.
  • Stabilization and calculation of the degradation due to initial exposition to the light (LID).
  • I-V test under real sun conditions and calculation of the STC parameters.
  • Measurement of the variation coefficients with irradiance and temperature.
  • Traceability referred to international primary references.
