The requirement for energy is increasing day by day throughout the world. Renewable energy plays a crucial role in fulfilling the energy requirement over nonrenewable energy due to its eco-friendly nature. Among different sources of renewable energy, solar acts as a major source due to its abundant availability. Due to the lesser efficiency of solar photovoltaic (PV) systems, an appropriate maintenance and monitoring is required. In recent years of research Internet of Things (IoT) is used to monitor and detect faults in solar PV systems. In this article, an IoT based solar monitoring and fault detection system is proposed. In the proposed system, voltage, current, and power of the solar PV system is continuously monitored and stored in the cloud for future and further analysis. From the monitored values, if any deviations found means it will be tracked and intimated to the operating personnel. The faults are identified and resolved immediately. In future, the proposed system is further can be improved for automatic fault rectification.
