Abstract— In this research, we offer a graphical user interface (GUI) that is both effective and efficient in order to control and monitor in real time the DC power that is generated by solar panels and the DC power that is used by load both locally and remotely. The server and the client both have their own graphical user interface (GUI). While the client GUI may be accessed by using a web browser from any part of the world, the server computer must be located close to the solar panels in order to monitor and manage activities locally. An authorised person can monitor and control all operations from any location in the world. LabVIEW and LabVIEW UI builder are used to create the graphical user interfaces for the server and client, while Arduino Uno, current and voltage sensors, relays, and a charge controller are utilised in the development of the hardware. It is possible to record and access a database file in order to do historical research on a renewable energy source (RES) system. The monitoring interface employs real-time measurement results in order to produce graphs displaying power, current, and voltage. This will also assist to improve the performance of the solar system that is currently in place, as well as the performance of other alternative sources of energy. This graphical user interface for the monitoring of the system displays graphs and metres for measuring voltage, current, and power output and consumption. The controlling function allows the solar system to be turned on or off, as well as increasing or decreasing energy consumption and generation, and switching to another system that is available..
