摘要
In order to detect power production degradation of a solar power plant (SPP) with at least one photovoltaic module (PVM), by which the detection of power production degradation, affected for instance by long term aging or soiling of the photovoltaic module of the solar power plant, is automated and carried out sensorless, it is proposed to determine the degradation by calibrating local measurements of data related to module/plant-internal parameters (PT) such as irradiance I and temperature T or electric power P and temperature as measurement data (MDI,ti, MDT,ti, MDP,ti against irradiance reference data (RDI,ti) for instance satellite data in the form of weather data for the same time and then analyze a variation of the calibration.
