Abstract
A method is presented to quantify thermal fatigue in the CPV die-attach from meteorological data. A comparative; study between cities demonstrates a significant difference in the accumulated damage. These differences are most; sensitive to the number of larger (..Delta..T) thermal cycles experienced for a location. High frequency data (<1/min) may; be required to most accurately employ this method
