A Comparative Study of the Productivity and Efficiency of Thermo-Solar Collector Models in Different Climatological Conditions in Some Regions in Yemen

Abstract

This research studies and analyzes the flat heating solar collectors, the focus solar concentrators and the parabolic cylinder concentrators in order to provide a solution to some environmental problems and the decrease of oil so as to invest operating the heating systems in Yemen. A method has been used to calculate solar heating power of meter square of effective surface, production and efficiency of usage in several zones in Yemen: Sana'a, sa'ada, Aden, Hodeida, Sayon, Ma'rib, and Rayyan. The research concludes that flat heating solar collectors, the focus solar concentrators and the parabolic cylinder concentrators have the following results: The heating power for each is 49-241W/m2, 153-792W/m2 , 350-2240. W/m2, respectively. The production solar energy stations of the above mentioned are: 1.4-9 Mj/m2, 5-30 Mj/m2 , 10-81 Mj/m2 , and the usage ratio of the productive power is 52-96% , 49-96% 45-95% . This indicates the potentiality of using these collectors and concentrators in different zones in Yemen.
