The thermal performance of solar systems for hot water service usually depends on the solar collectors. Evacuated tube solar collector with heat pipe has been developed to improve the thermal efficiency of solar energy collector. In solar energy system, collector modules should be arranged in series and/or parallel pattern. The experiment is carried out to investigate the thermal performance for the module of solar collector in series and parallel, respectively. The results from this study will be presented as the basic data for the arranging pattern of many solar collectors.
