Abstract
Solar energy is becoming one of the most expanding renewable energy it is getting more prominence. Sun trackers can substantially improve the electricity production of a photovoltaic (PV) system. This paper proposes a novel design of a dual-axis solar tracking PV system that utilizes the feedback control theory along with a four-quadrant light-dependent resistor (LDR) sensor and simple electronic circuits to provide robust system performance. Our project will include the design and construction of a microcontroller-based solar panel tracking system. In hardware development we utilize LDR’s as sensors and two servo motors to direct the position of the solar panel. Dual-axis solar tracking allows more energy to be produced because the solar array is able to remain aligned perpendicular to the sun. In this paper to make better analysis Dual axis solar tracker is implemented for standalone system and simulation analysis is performed on the grid-connected PV station. To perform the experimental analysis the data is collected from Meteorology of Asmara and NASA. Comparative results have been presented between static and automatic solar dual-axis stand-alone systems. Moreover, comparison will be made among the output power results of our system with the conventional (Static) solar system. Simulation results have presented for the grid integrated system which shows better performance results.

Energy is the main factor in the development of a nation
Single-axis trackers are placed into the following classifications: horizontal single-axis tracker (HSAT), vertical single-axis tracker (VSAT), tilted singleaxis tracker (TSAT), and polar aligned single-axis tracker (PASAT)[4]
Sunil Kumar Jilledi et al.: Design and Simulation of Dual Axis Solar Tracker for Optimum Solar Energy Absorption mention that a TSAT at a tilt angle of 5° increases the annual collection radiation by 10% compared to an HSAT
Summary
Energy is the main factor in the development of a nation. An enormous amount of energy is extracted, converted, distributed and consumed in the global society daily. If a solar module or device is turned to face the sun throughout the day, its energy output increases Single-axis trackers are placed into the following classifications: horizontal single-axis tracker (HSAT), vertical single-axis tracker (VSAT), tilted singleaxis tracker (TSAT), and polar aligned single-axis tracker (PASAT)[4] These terms don’t seem to be used in most articles discussing tracking methods. Sunil Kumar Jilledi et al.: Design and Simulation of Dual Axis Solar Tracker for Optimum Solar Energy Absorption mention that a TSAT at a tilt angle of 5° increases the annual collection radiation by 10% compared to an HSAT. Dual-axis trackers allow for optimum solar energy levels due to their ability to follow the Sun vertically and horizontally. Dual-axis solar trackers have both a horizontal and vertical axis trackers they can track the sun's apparent motion virtually anywhere in the world
