Design Development of Parabolic Trough Solar Concentrator for Water Heating
Abstract— In this paper a survey of parabolic trough solar concentrator and its application for heating water is provided. Initially, an overview of environmental related problems to the use of conventional sources of energy is presented and benefits offered by renewable energy systems are outlined. An introduction of flat-plate collector and its characteristics are compared with parabolic trough solar collector, and the corresponding results are obtained for PTC. This is followed by an optical, thermal and thermodynamic analysis of the collectors and description of the methods used to evaluate their performance. A tracking system is used to track the sun rays so as to get the maximum intensity which would be used for a wide range of application and provide significant benefits, therefore, they should be used wherever possible.
