The main aim of this project is to implement solar tracker system and failure detection. The sun is tracked by using Light Dependent Resistor’s and its position changed in such a way that it generates efficient power output as compared to fixed panel. The solar panel is moved with the help of servomotor, so that sun’s light is able to remain aligned with the solar panel .Power failure detection is recognized by with the help of IOT platform i.e., Blynk App. Blynk app is used to identifying the voltages of solar panel and sensors respectively. This project is low at cost andproductive.ESP32micro controller has bluetooth and wifi connectivity option to communicates with mobile to the IoT platform, where data restored, processed and can be accessed using a computer or any smart device from anywhere. The system updates data from sensors to IoT server for every10 seconds. The stored data can be used for further analysis climate, to reduce pollution, save energy and provide an overall living environment enhancement for smart city applications.
