EXPERIMENTAL STUDY ON THE OPTIMUM HARVESTING OF SUNLIGHT FOR AN EFFICIENT SOLAR ENERGY SYSTEMAbstract:Reducing high energy consumption and the associated cost are significant to our daily life,especially with the current economy. The paper presents the work done for the capstone seniordesign project and its subsequent improvement and consolidation. The objective of the project isto develop an efficient solar energy system with an automated solar tracker for the optimumharvesting of sunlight. This project also exemplifies the integration of various aspects ofengineering technology curriculum including the automation, product and process design,design for manufacturability and design for durability concepts.The solar tracker is used to maximize the absorption of the solar power by adjusting the panelautomatically to be perpendicular to the sun’s ray. This is done by using photo-sensors tomeasure the irradiance of the sun and providing a feedback signal on the current position of thepanel. The position of the solar panel is automatically aligned to the direction of the sun’s raysby calculating both the seasonal movement and current location of the sun. The panel orientationis processed by the use of two linear actuators, the first one control the azimuth move (season)and the second one the zenith move (day).The solar tracker system is divided into two parts the hardware and the control. In the hardware,the base is designed and fabricated to mount the solar panel and the micro-controller. The controlprogramming was developed using C++ language. The system is designed to be robust andlightweight for enhanced durability and mobility.The paper will present the technological aspects of developing a dual axis control for theautomated solar tracking system for the optimum harvesting of solar energy. The lateralintegration of the various pedagogical aspects of engineering technology curriculum includingthe concepts in automation and product and process design will also be discussed in detail.
