As the IoT environment, in which all objects are connected and information is shared, is being expanded, new services are being applied to the traditional energy services gradually. In this paper, the PhotoVoltaic(PV) monitoring system, which is required to develop efficient management service for Solar power generation system, was developed by applying IoT technology and it shows that it is possible to construct an efficient monitoring system at low cost. For the IoT based PV monitoring system, we developed IoT gateway based on inexpensive Raspberry pi hardware and adopted the Message Queuing Telemetry Transfer (MQTT) protocol at IoT gateway and Smart Phone. And also we can down the cost by using the Smart Utility Network(SUN) communication of the license-exempt band which is sub-1Ghz band. In the future, we are going to develop optimal database system and data analysis tools for this IoT Gateway and its performance will be verified.
