IoT A Diagnosis Syetem of Photovoltaic Generation Based on IoT

摘要

The present invention relates to a photovoltaic power generation diagnosis system and, more specifically, to an IoT-based photovoltaic power generation diagnosis system which compares a difference of a power generation amount within grouped photovoltaic power generation devices through trend analysis of the power generation amount during the same period in the past through machine learning using artificial intelligence and the like rather than state diagnosis through comparison of an actual power generation amount with a calculated power generation predictive value of a specific photovoltaic power generation device so as to diagnose a state of the specific photovoltaic power generation device, thereby increasing accuracy of the state diagnosis. Collection of data for abnormality diagnosis is performed by using an IoT network so as to perform installation and operation of the system at a low cost and perform quick transmission and reception of the data. Moreover, the IoT-based photovoltaic power generation diagnosis system comprises a photovoltaic power generation device and a diagnosis server.
