The renewable energy source is a non-depleting energy source, which is abundantly present in our climate. At present, the existing research areas are focused on renewable energy sources. This source of energy is clean and pollution-free. The only significant problem associated with this is its performance and profitability. We come across several solar panels every day. Those panels are fixed. We took this further on with tracking devices to solar panels. These solar tracking devices come in fixed structures with a single axis and dual axis. The Dual-axis tracking mechanism is quite effective as it is capable of capturing more irradiance than the other. These are capable of shifting the system in various co-ordinates of latitudes and longitudes according to the position of the sun. Fixed axis devices are capable of capturing the maximum intensity of the sun for one particular moment throughout the day when the sun is at zenith. These trackers are powered by small solar cells that provide motion to the panel according to the location of the sun. Also, it is not recommended to use solar trackers with small PV arrays because of the energy consumption of the driving systems, which vary from 2% to 3% of the energy increase delivered by the solar trackers. This paper intended to review different solar tracking system that increases the solar power output. A solar tracking system, using a photovoltaic device to monitor the changing solar position, is disclosed. The photovoltaic device is automatically overridden when the sun ceases to be the brightest point in the sky, for instance during times of partial cloud cover, and the machine attempts to attain the brightest spot in preference to the sun.  The override system is clock-driven and moves the tracking system to approximate the solar position so that when the sun re-energizes as the brightest object in the sky, the photo-voltaic device can immediately reacquire the sun.
