This study has been undertaken for the characterization and to study the effect of composite-based nanofluids on thermos-thermal conversion in solar evacuated tube water heating systems. Enhancement in solar radiation absorption leading in the direction of the optimum heat transfer rate. Ultimately which is resulted in effective and efficient heat transfer. This paper is an exploration of harvesting solar energy through the usage of nanofluid-based evacuated tube solar collector. The synthesis of TiO2:CuO:Cr2O3 based nanofluid made of equal proportions of nanoparticles, prepared by the ultrasonic probe method. The most affecting parameter stability of nanofluid has been checked for different time intervals. Various important properties of nanofluid have been studied and observed shown remarkable improvement in thermal properties. The derived results can lead towards the development of highly efficient domestic solar water heating systems in replacement of water.
