Abstract: The performance of two discrete solar heating systems have been studied. One of the collector systems was designed to track the sun while the other was to remain stationary. A 30 day performance test for both collectors was carried out on clear days and a semi-cloudy days. The study revealed that for the experimental period and under the same conditions the tracking and non-tracking collector indicated mean values of the useful heat gain of 290 and 220 W m 2, overall heat loss coefficient of the collectors being 2.5 and 5.8W m 2K, while the mean thermal efficiencies of the collectors were 56 and 43%, respectively.
