Abstracts: The dual threats of energy depletion and global warming place the development of methods for harnessing renewable energy resources at the centre of public interest. Solar energy is one of the most promising renewable energy resources. Sun trackers can substantially improve the electricity production of a photovoltaic (PV) system. By using normal solar tracker one can utilize solar energy but having low efficiency. By using Dual Solar Tracker we can increase the efficiency of pay loads such as photovoltaic cell. Dual Solar Tracker has two degree of freedoms (D.O.F). Since we all know that sun has continuously changing angles throughout a whole year. Hence Dual Solar Tracker can rotate in both directions. It can follow the sun at any angle, which results in increment in efficiency of photovoltaic cell. Our aim is to obtain maximum electricity through a natural way and we carry a success with the help of proper guidance.
The renewable energy sector is rapidly gaining ground as a new growth area for many countries with the great potential it presents ecologically and economically. Solar energy plays an important role as a primary source of energy, especially for the rural area. This article presents the design and development of the Arduino high efficiency dual axis solar tracking system. In addition, the ultimate goal of this project is to track the maximum solar source to power the solar panel. The project is divided into two stages, which are the development of hardware and software. In hardware development, five light-dependent resistors (LDRs) have been used to capture the maximum light source. Two servo motors have been used to move the solar panel to the maximum location of the light source by LDR. In addition, the code is constructed using the C programming language and directed to the Arduino UNO controller. The efficiency of the system has been tested and compared to the static solar panel at various time intervals, and shows that the system reacts best at 10-minute intervals with a constant voltage generated. Therefore, the system has been tested working to capture the maximum source of sunlight for high efficiency solar utilization applications.
