Testing the Reliability and Safety of Photovoltaic Modules: Failure Rates and Temperature Effects

PV Module ReliabilityUnderstanding 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.
