Guidelines for qualifying PV modules, components and materials for operation at high temperatures1 Scope This document defines additional testing requirements for modules deployed under conditions leading to higher module temperature which are beyond the scope of IEC 612151 and IEC 617301 and the relevant component standards, IEC 62790 and IEC 62852. The testing conditions specified in IEC 612152 and IEC 617302 (and the relevant component standards IEC 62790 and IEC 62852) assumed that these standards are applicable for module deployment where
