Acceleration Factor prediction for accelerated life testing of photovoltaic (PV) modules plays a major role in estimating the reliability of modules in field. Accelerated stress tests are designed in such a way that the test replicates the failure mechanism that the module experiences outdoor. However, in most cases of PV modules, complete data on degradation measurement (from

Abstract The reliability of photovoltaics is commonly studied at the module level. Many reliability problems originate from module attributes, such as metal interconnections to cells, junction boxes. However, significant work in reliability can also be done prior to module design. Testing for reliability earlier in the research cycle increases the probability of avoiding common
