Evaluation of the SOPHIA CPV module round robin on power rating at CSOC

As the SOPHIA round robin aims for comparing different power rating methods, all partners agreed to use the same measurement guideline. This guideline considers the module alignment, the data requirement and the duration of data collection. Three methods to calculate the rated power from measurement data based on regression, averaging or translation are already evaluated using data of the first four partners. Initial results show maximum deviations in the rated power output between the test labs of less than about four per cent for the investigated rating methods.
