Abstract
In this paper the performance of a flat-plate solar collector for water heating is analyzed under the weather condition of Sebha in the south of Libya. The effect of collector components' properties, including cover type, absorber plate type, and tilt angle, is predicted. Two days of 21 January and 21 July, at a clock of 13 were selected the analyzing. The working fluid is water, and its circulation is by thermosyphon. By applying the control equations through a matlab computer program, the results show that for the three types of collector's covers, glass, polycarbonate, and polytetrafluoroethylene, the last one gave the best efficiency. For collector with the absorber plates of black copper have the higher efficiency than those with the copper and iron absorber plates. The collector tilt angle selected was 27o for the required flow rate.
