Abstract: Energy is one of the building blocks of modern society. The growth of the modern society has been fueled by cheap, abundant energy resources. Solar energy is a form of renewable energy which is available abundantly and collected unreservedly. In this thesis the application of solar energy using parabolic trough is analyzed. Parabolic trough technology is currently the most extended solar system for electricity production or steam generation for industrial processes. It is basically composed of a collector field which converts solar irradiation into thermal energy and a conventional thermal to electric conversion Rankine cycle. The prototype of the parabolic trough concentrating solar is collector manufactured using the available materials and equipment in the workshop of Mechanical Engineering Department at AAiT. The prototype is designed using SolidWorks and analyzed in Cosmos software. The thesis work elaborates in detail the steps undertaken in the fabrication of the parabolic trough and other accessory parts used in the experimental setup such as heat exchanger design and pump selection. An experimental setup has been developed to investigate the performance of the parabolic trough. Measurements of total direct radiation on the plane of the collector, ambient temperature, wind speed, water flow rate, inlet and outlet temperatures of the water inside the absorber tube are collected and employed in studying the performance of the parabolic trough. A data logger and a computer were employed for data acquisition and the outputs of the experiment are illustrated with the help of graphs plotted using the data logger data import-wizard and Matlab software. Finally, the efficiency which is used as a measure of performance is calculated. In addition, the experimental results are compared with the result obtained using a mathematical model.
