IEC 63126:2020/CR1:2022 Guidelines for qualifying PV modules, components and materials for operation at high temperatures. | Status: Superseded, Withdrawn

1 Scope This document defines additional testing requirements for modules deployed under conditions leading to higher module temperature which are beyond the scope of IEC 61215‑1 and IEC 61730‑1 and the relevant component standards, IEC 62790 and IEC 62852. The testing conditions specified in IEC 61215‑2 and IEC 61730‑2 (and the relevant component standards IEC 62790 and IEC 62852) assumed that these standards are applicable for module deployment where the 98th percentile temperature (T98th), that is the temperature that a module would be expected to equal or exceed for 175,2 h per year, is less than 70 °C.

NOTE 175,2 h represents 2 % of a total year as some thermal failure modes are a function of time at temperature and not sensitive to day-only or night-only exposure.

This document defines two temperature regimes, temperature level 1 and temperature level 2, which were designed considering deployment in environments with mounting configurations such that the T98th is less than or equal to 80 °C for temperature level 1, and less than or equal to 90 °C for temperature level 2. This document provides recommended additional testing conditions within the IEC 61215 series, IEC 61730 series, IEC 62790 and IEC 62852 for module operation in temperature levels 1 and 2.
