Solar energy is rapidly becoming an alternative means of electricity source. Fossil fuels are seriously depleting, thus the need for alternative energy sources is a necessity. To make effective use of solar energy, its efficiency must be maximized. A feasible approach to maximizing the power output of a solar array is sun tracking. This paper, therefore, presents the design and construction of a solar tracking system that positions the solar PV panel in proper orientation with the sun to always receive direct radiation. The prototype is designed around a programmed microcontroller which controls the system by communicating with the sensors and motor driver based on the movement of the sun. Automatic Sun Tracking System is a hybrid hardware/software prototype, which automatically provides the best alignment of solar panel with the sun, to get maximum output (electricity). By doing this, the efficiency of the panel can be increased by as much as 15-25%.
Microcontroller Based Dual Axis Sun Tracking System for Maximum Solar Energy Generation
Solar energy is becoming a promising renewable energy technology. Conventional fixed solar panel with a certain angle limits there area of sun exposure due to rotation of Earth. The automatic solar tracking system solves this problem. In this paper a dual axis solar tracker is designed and implemented to track the sun in both azimuth and altitude axes by using an AVR microcontroller. The implemented system consists mainly of the ATmega 328 controller, DC motors, light sensors and relays. The results show that the designed low cost sun tracker increases the output power generation efficiency by 25-30 % as compared with the fixed panel systems. The effect of temperature and panel covering by colored cellophane, on the performance of the designed system is also studied. The temperature and the colored cellophanes decrease the output power of the solar panel.

The phrase the sun is the source of all energy implies that solar energy is an essential element for the earth. Sun-powered vitality is fast becoming a substantial approach for renewable energy source assets. The sun is a plentiful source of vitality, and this sunpowered vitality may be effectively dealt with by employing sunlight-based photovoltaic cells and photovoltaic impact to convert sunpowered 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.

INTRODUCTION The global warming problem has at present drawn worldwide public consideration to issues connected to energy preservation and alternate energy. A few energy preservation strategies, for example, energy, reusing and energy collecting procedures, have been proposed to lessen pointless vitality squander from commercial apparatus. What's more, elective energy, for example, wind, warm or sunlight based energy is renewable and addresses pollution issues. The solar energy introduces the benefits of low cost and contamination free qualities [1]. These are keys to comprehending compounding a global calamity crisis and decreasing ozone harming substance emanations. Along these lines, this renewable energy has been increasing expanding prevalence in various nations. Solar based energy in future to may be the most proficient decision as to energy generation. However, despite everything it exceeds different sorts of energy, for example coal, atomic, and gas, energy, since it causes zero contamination, and takes into consideration simple upkeep. In fossil fuel reserves day by day is very depleting and Price of fossil fuels is increasing very fast. This energy is very affected for our health, air population, environment, emission of the greenhouse [2]. So in the future, need several thoughts for electric energy. Some researchers they are getting alternative way for clean energy development. They are getting renewable energy (solar energy, wind energy, bio-mass energy) sources. So, solar energy is considered as one of the best renewable energy sources [3]. In solar energy the solar panel tracking system plays an important role in achieving maximum efficiency in solar power generation [4].

A Microcontroller Based Dual Axis Tracking System for Solar Panel
2019 3rd International Conference on Electrical, Computer & Telecommunication Engineering (ICECTE)
Solar energy is one of the most promising renewable energy resources that recently have become broader in current technology. This paper presents the technique how Ohm’s law and power equation applies to generate more energy from solar photovoltaic (PV) panels. To implement automatic dual axis and a polar single axis solar tracker system is used. It contains a locked vertical axis and a flexible horizontal axis, which is regulated by a motor. To get the maximum power output and highest efficiency, trackers always track the sun and change panel position accordingly. The tracker automatically changes its position after every 2 to 3 degrees of misalignment, to prevent the power loss created by running motor continuously. The light intensities of both sides were compared by the sensors and move the panels towards the light. The panel continuously moves until the tracker detects the equal light falls on both sides. This project helps to improve the solar irradiance of the panel.

Solar energy is a form of renewable energy that is generated through the use of solar panels. However, since solar panels are usually stationary, they don't always align with the sun's position as it changes throughout the day. This can result in lower energy output. To address this issue, a solar tracking system has been developed. A solar tracker is a system that automatically adjusts the position of the solar panel to track the sun's movement and maximize the power output. This paper reviews different types of tracking mechanisms used in solar tracking systems. There are two main types of solar trackers: singleaxis and dual-axis trackers. Single-axis trackers are suitable for areas around the equator where there is less variation in the sun's position. On the other hand, dual-axis trackers are better suited for regions where the sun's movement is tracked from east to west throughout the day and from east to north or south throughout the seasons. This paper aims to review various tracking mechanisms used in solar tracking systems. The objective is to explore different types of mechanisms that can improve the efficiency of solar panels by enabling them to constantly align with the sun's position.
