This project presents an open hardware or software test bench for solar tracker and fault detection .The suggested prototype runs a dual axis sun tracker and fault detection on an Arduino Uno, an open source prototyping platform with user-friendly hardware and software. It is built on a solar tracker, which rotates automatically to follow the sun using four LDR sensors and two servo motors. Solar power facilities need to be watched over for optimum power output and to find the problem’s origin .This helps to assess the solar plant’s efficiency in terms of power output while keeping a look out for dust accumulation and loose solar panel connections that lower the panels’ power output. We suggested a technique to locate panel imperfections and tracking.

The solar panels are placed at an angle towards the sun by a solar tracker. It is a sophisticated sun-monitoring device that has the ability to rotate the panels to follow the sun’s path across the sky. It makes it easier for the panel system to capture the most sunlight and maximise energy output. The use of a solar energy tracker has numerous benefits. A solar energy monitoring and fault detection solution is crucial when it comes to solar power systems if you want to keep your system producing effective results. You get access to useful data insights when you monitor the functioning of your solar system and look for faults. The appropriate solar monitoring system for your solar array must be installed. It is quite dependable and aids in reducing energy consumption in general.
