Sun-powered vitality is fast becoming a substantial approach for renewable energy source assets. The sun is a plentiful source of vitality, and this sun- powered vitality may be effectively dealt with by employing sunlight-based photovoltaic cells and photovoltaic impact to convert sun- powered energy into electrical vitality. The solar tracking system maximizes the power generation of solar system by following the sun through panels throughout the day, optimizing the angle at which panels receive solar radiation. Compared to stable solar panels, a solar tracking system using solar panel linear actuators or gear motors can increase the efficiency of solar panels by 25% to 40%. The transformation efficiency of any sun-based application increases when the modules are consistently adjusted to the optimal edge as the sun crosses the sky. A dual-axis tracker allows panels to move on two axes, both north-south and east-west parallel. This paper presents the design and implementation of a dual-axis solar panel based on the Arduino microcontroller. Keywords-- Arduino UNO, LDR, Servo motor, Solar panel, Solar tracker INTRODUCTION The exploitation of coal, oil, natural gas, and other mineral resources and the development of nuclear energy are all aimed at meeting energy needs. At the same time, the carbon dioxide produced by the use of mineral energy has caused a global greenhouse effect. The use of this energy source has many side effects. Solar energy, wind energy, tidal energy, and other new energy all use the innate energy of nature. The process of using them is basically collection, so these are clean energy. More and more countries and regions value its development and use and increase investment. Among these clean energy sources, solar energy is the most used, the most stable, and the most convenient [1]. The sun is a numerous source of vitality, and this sun-powered vitality may be effectively dealt with by using sun-oriented photovoltaic cells and photovoltaic impact to convert vitality into electrical vitality. However, the transformation capability of a standard PV cell is limited. The major reason for this is because the output of PV cells is dependent on the light intensity, and with the sun's location in the sky changing constantly, the efficiency of a solar panel would be much lower at a specific time of day and year. Solar PV cells are most productive when they are perpendicular to the sun and least productive when they are parallel to the sun. As a result, solar panels are necessary to increase energy output while also improving efficiency. Through the programming-based arrangement, the sun-based tracker also provided a valuable solution for poor nations to easily coordinate it into their nearby planetary system. The analysis discovered that using a stepper motor allows for precise tracking of the sun and the LDR resistors needed to determine the solar- powered light force [2]. Experts predicted that incorporating a global positioning framework with a sun-oriented board will provide precise and appropriate responses to meet the demands of the force in a variety of operating scenarios. A solar-powered global positioning framework designed with microcontrollers and LDRs to follow the sun and modify its location as needed to increase energy production. The
