Behavior of Interconnect-Failed PV Modules Under Standard Test Conditions and Actual Operation Conditions

Comparisons of indoor measurements under standard test conditions (STC) and outdoor measurements under actual operation conditions of ten-year-used interconnect-failed PV modules were described. In the indoor measurements under STC, no sample modules showed the output power degradation of more than 20% from the rated power. In the outdoor measurements of the sample modules, the open-circuit voltage decreased in a discrete value with a half volt...
