Annex 1

Criteria of Test and Evaluation Basis The requirements for testing base upon the state of technology and recognized technical regulations of VDE and DIN-standards as well as international standards, which may be partially used for the definition of the tests. Furthermore, the long-term experiences in fields of testing and certification of the TÜV Rheinland Group incorporate in the assessment. The following standards are applied directly or indirectly or are used as technical basis for the measurements to be performed. PV-Module
