| Summary: | This research deals with optimum design of parabolic solar collector with exergy analysis, a mathematical model built to reach the optimum design for the parabolic trough solar collector by three main parts. The first part concentrated on optimal design depends on the measured values of the solar intensity radiation fell on the city of Kirkuk and to obtain solar absorbed radiation, while the second part revolves on energy analysis of parabolic solar collector, and the final part was carried out exergy analysis of parabolic trough solar collector. The exergy efficiency took as a measurement to found the optimum operation condition (inlet water temperature and mass flow rate) and design parameter (concentration ratio, length solar collector and width solar collector). The design depended on the climatic conditions of the city of Kirkuk after it measured, also it show’s the importance of using exergy analysis in the design by studying the impact of some of the basic transactions of the solar system.
