This paper presents the main aspects of implementing a laboratory for testing qualification and approval related to crystalline silicon terrestrial photovoltaic devices. . Kiwa PVEL's Product Qualification Program (PQP) and Scorecard are the global solar industry's trusted resources for PV module reliability and performance data. In this 11th edition of the Scorecard, Kiwa PVEL is proud to showcase a broad range of Top Performer manufacturers and module model types. . NREL is a national laboratory of the U. Department of Energy Office of Energy Efficiency & Renewable Energy Operated by the Alliance for Sustainable Energy, LLC. gov/publications. Qualification testing is a short-duration (typically, 60-90 days) accelerated testing protocol, and it may be considered as a minimum requirement to undertake reliability testing. The goal of qualification testing is to identify the initial short-term. . Field failures in advanced modules can be catastrophic, with some studies documenting power losses from 5% to over 50% due to material-related degradation. The core question is no longer what materials to use, but how to qualify them to ensure 25-year reliability in the real world. . NLR's photovoltaic (PV) reliability and system performance research focuses on R&D to improve PV technologies and more accurately predict system performance over time. Our PV reliability research and development provides companies with the information they need to improve PV product lifetime. .
