Abstract

A research has conducted on "Fabrication of Flat Plate Collector as a Solar Energy Water Heater with One and Two Covers”, using the experimental methods. The experiments were done by putting two types of solar collector on the area that the solar beam can falls freely that perpendicularly to the surface of the collectors. The measurement were carried out on the intensity of solar radiation coming, hot water temperature and the lost heat by using equipment of a simple pylheliometer and a mercury thermometer. This measurements were done in 60 minutes interval every day for 14 days of observation. The results obtained for both types of flat plate collectors produced 66 liters of water every day. The two tier covered flat plate collector reached the highest temperature of 95o C, which was higher than its of the single-tier covered flat plate collector of 84o C. This result was due to the more layers cover the less heat that lost through the top surface of the flat plate collector. The highest temperature of the hot water that accommodated in the tank was 51o C for the double layer collector lid and 47° C for the one layer of collector lid
