The application of solar energy in the form of solar water heating (SWH) system is most popular and useful for domestic, commercial and industrial purposes in Palestine, but it is found that the application of its depends on using different types of SWH systems. This paper investigates experimentally the performance of flat plate collectors (FPC) and evacuated tube collectors (ETC), which are the most common use in Palestine. A three locally made solar water heating systems, with 0.48m2 serpentine type flat plate collector(S-FPC), 0.48m2 parallel type flat plate collector(PFPC) and 0.31m2 U-Pipe evacuated tube collector (ETC) were installed on the rooftop of Energy Research Center building at Al-Najah National University, in Nablus (32.227099N, 35.222209E), Palestine. The data were gathered in 3 months of the same weather conditions during May , June and July 2019. Then the performance of each system was studied and compared with others. The results show that the daily energy collected by S-FPC is 1015 Wh/m2 , 1415 Wh/m2 for P-FPC and 1854 Wh/m2 for ETC. The system efficiencies were 26%, 38% and 49% respectively for S-FPC, P-FPC and ETC. Keywords: Solar water heating, performance analysis, weather conditions, economical analysis .
