Abstract: A photovoltaic (PV) power generation system is described. The system includes at least one PV module comprising a plurality of PV cells, a plurality of sensors, and a processing device communicatively coupled to the plurality of sensors. The processing device is configured to determine a power output each of the plurality of PV cells, receive data from the plurality of sensors, and identify a faulty sensor within the plurality of sensors based at least partially on the determined power output and the received data.

Abstract: A method for monitoring a wind turbine is provided. An operating parameter, including a parameter value and a data quality value, is created by a controller. The parameter value is based on a signal received by the controller from a source. The data quality value indicates the source and/or a reliability of the parameter value. The operating parameter is processed based on the data quality value. Processing may include, for example, creating a graphical representation of the operating parameter or assigning a weight to the operating parameter for use in a calculation.
