Three types of solar system for hot water supply of middle temperature over 80℃ are developed. The collection performance between a collector with non-reflective pair-glass of high temperature and the other two collectors with normal single-glass was compared each other. Collector A of normal-glass, collector B of non-reflective pair-glass and collector C of vacuumed pair-glass were prepared for the test. A solar system, which consisted of the collector B, was simulated under the Sapporo weather conditions due to METPV-2 data. As the result, a heat transfer coefficient of the collector A was 3.27W/m^2K, and those of the collectors B was 2.51W/m^2K and C was 1.71W/m^2K respectively. The rate of the heat transfer coefficient for the collector B to the collector A was 77%, and however, that of the collector C to the collector A was decreased to 52%.
