SOLAR TRACKING SYSTEM A DESIDERATUM USING LDR AND MICROCONTROLLER PACKAGE

The renewable-energy sector is fast gaining ground as a new growth area for numerous countries with the vast potential it presents environmentally and economically. Solar energy plays an important role as a primary source of energy, especially for rural area. This paper presents the design and development of high-efficiency dual-axis solar tracking system using Arduino platform. Furthermore, the ultimate objective of this project is to trace the maximum sunlight source to power the solar panel. The project is divided into two stages, which are hardware and software development. In hardware development, four light dependent resistor (LDR) has been used for capturing maximum light source and two servo motors have been used to move the solar panel at maximum light source location by sensing LDR. Moreover, the code is constructed using C programming language and targeted to Arduino UNO controller. Therefore, the system has been proven working for capturing the maximum sunlight source for high efficiency solar harvesting applications
