Decision: This Decision Sheet sets forth a uniform approach to maintain the certification of PV modules that have, or will, undergo modification from the articles originally certified. Changes in material selection, components and manufacturing process can impact electrical performance and reliability of the modified product. The recommended test sequences given below have been selected to identify adverse changes to the modified product. Those products meeting the requirements of the relevant standard after retesting are considered to be compliant and will be issued an amended CB Conformity Assessment Certificate and an Amended Technical Report Form. The number of samples to be included in the retesting program and the pass/fail criteria is to be taken from the standard originally used to certify the product (either IEC 61215 or IEC 61646). The document is organized by major modification headings and specific supporting examples. Following this is the recommended retesting sequence with parenthetical reference to the specific clauses of the relevant IEC standards. For the modifications listed below, the Qualification Approval tests in IEC 61215 and IEC 61646 shall be used as a guideline by the National Certification Body (NCB) and Certification Body Testing Laboratory (CBTL). For the modifications listed below, the Qualification Approval tests in IEC 61215 and IEC 61646 shall be used as a gu
