The solar parks are now quickly becoming one of the most significant renewable form of energy systems, hence there is a pressing need for more streamlined use of the aid they provide, as well as error discernment and performance difficulties. The Internet Of Things (IoT) technology attempts to bridge the gap by providing low-priced, modest and long-term results for solar park efficiency. We describe a monitoring and alerting system in this project that is employed in the early identification of Potential Induced Degradation (PID) and Hotspots failures, which can result in a considerable reduction in solar panel performance. Certain practical characteristics like as temperature, voltage, and humidity are continually monitored at the panel level in order to do this. It is mainly focused on the installation of Internet Of Things for remote monitoring and performance evaluation of a solar facility. This will make preventative maintenance, solar panel defect detection, and real-time monitoring much easier. Solar towns, smart villages, micro grids, and solar street lighting are just a few of the possibilities for this technology. In the present-day scenario, use of renewable energy has increased at a higher rate than at any previous time in history. The proposed system calls for an online display of solar energy's power use as a sustainable energy source. This monitoring is carried out with the help of an Arduino and an IoT server.
