Monitoring device, solar power generation device, monitoring system, and monitoring method

摘要

The monitoring device (1) stores, for each of the plurality of divided periods, a reference value for the generated power of the solar cell panel (2) at a time when the solar cell panel (2) is not shaded in a clear sky state ( 11) and the measurement value in which the time information indicating the time when the measurement value of the generated power of the solar battery panel (2) is generated and the period information indicating the divided period in which the measurement value is generated are associated with each other. An acquisition unit (13), an estimation unit (14) for estimating a weather condition at the installation location of the solar battery panel (2), a measurement value acquired by the acquisition unit (13), period information and time information of the measurement value And a determination unit (15) that performs an abnormality determination process that determines that the solar cell panel (2) is abnormal when the measured value is less than the reference value. 15) is an estimation unit (1 An abnormality determination process using the measured values estimated weather state is generated at the date and time is sunny in).
