Abstract
[Abstract]: The domestic evacuated tube solar collector (ETC) can easily achieve during its operation relatively high water temperature levels approaching 100 oC. Operating the collector at such high temperatures induce considerable losses in form of latent heat working to evaporate the water into steam and excessive heat losses due to the wide difference to the ambient temperature. This paper presents an analysis based on field measurments taken over a prolonged field test aiming to identify the impact of water-discharge temperature on the performance of the subject ETC. Ways of improving collector efficiency and energy yield by adjusting the water-discharge temperature are discussed. During the assessment the water temperature has been set at different levels from 25 to 98 oC before being discharged to the user.
