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 98^th percentile temperature (T_98th), 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.

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 T_98th 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.
