Photovoltaic ModulesUnderstanding What Photovoltaic Testing Means to the Bottom Line

Photovoltaic modules are designed to meet the reliability and safety requirements of national and international test standards.

Qualification testing is a set of well-defined accelerated stress tests – irradiation, environmental, mechanical and electrical – with strict pass-fail criteria based on functionality/performance, safety/insulation, and visual requirements. 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 and the goal is to identify the initial short-term reliability issues in the field.

While the qualification testing and certification is primarily driven by marketplace requirements, safety testing, however, is a regulatory requirement where the modules are assessed for the prevention of electrical shock, fire hazards, and personal injury due to electrical, mechanical, and environmental stresses in the field.
