The objective of this study is to make a comparative study of the operation performance of different type of solar collectors. A flat-plate collector, a single-glazed evacuated collector and a double-glazed evacuated collector are used in this study. These 3 type of collectors are connected in series in the order of a flat-plate collector, a single-glazed evacuated collector and a double-glazed evacuated collector. This experimental facility is a kind of a solar system with a controller, a heat exchanger, a storage tank and a circulation pump. Each collector has a different collection area(flat-plate collector-6.00m² total area/5.61m² aperture area, double-glazed evacuated collector-6.04m² total area/4.92m² aperture area, single-glazed evacuated collector-7.65m² total area/5.61m² aperture area) and its performance characteristic respectively. The experiments have been demonstrated at around 70?C operating temperature(flat-plate collector inlet temperature). The thermal collecting efficiencies of each collector are obtained under the different insolation and operation condition as a result.
