Testing PV Module Reliability

Testing PV Module Reliability

Many globally recognized testing laboratories currently employ qualification testing as a means to identify initial short-term reliability issues in the module's design and construction. The demand for this testing is driven by marketplace requirements and is mandatory in all of Europe, Japan and parts of Asia. Qualification testing attempts to identify in advance the design and construction errors that can result in reducing the module's performance or causing failure over its lifetime. Many common failure mechanisms, such as broken interconnects, moisture ingress, delaminations, microcracks, hot spots, ground faults and structural failures can be uncovered through qualification testing. This type of testing is a 65- to 90-day process designed to accelerate and induce many of the same failure mechanisms to which the module is subjected in the field. Qualification tests ar...
