Light and elevated temperature induced\degradation (LETID) test-Detection (PV Module)

• Temperature: 75±3℃
• Current: 2*(Isc-Impp)
• Time: 162 +8/-0h per cycle

•If the sample testing process has already entered the regeneration stage, stop the current injection:

-The hourly average value of the measured voltage corrected for temperature exceeds the sum of the minimum dark voltages

- Or the temperature-corrected dark voltage in the dark voltage diagram has reached the minimum value for 10 consecutive hour

•The final power should meet :

 Pfinal ≥ 0.97 × PBO × (1 - r[%] / 100)
