Popis:	29th European Photovoltaic Solar Energy Conference and Exhibition; 2609-2611 In large multi-megawatt photovoltaic generator plants, usually there exists a fine grained monitoring system that logs various parameters relevant to the generation, operation and maintenance of the arrays. Usually, with a reasonable amount of similar units in the plant, failure detection can be performed by continuous comparison of individual parts, e.g. comparison of all strings’ DC powers. Thereby, time-constant deviation factors are expected, e.g. by different power rating or measurement sensor calibration constants. This exhibits influence of various effects on the production power of the plant.
